Quality Tour Guide Audio System & Wireless Tour Guide System Factory

Many customers who purchase wireless audio guide devices will privately ask: Does this brand have its own R&D team? After all, a brand without R&D capabilities will have problems with its products within half a year. Either the products won't be compatible with the local voltage or language, or it will be impossible to upgrade the functions later. For those customers who need to use it for a long time and adapt to international scenarios, choosing an audio guide device is essentially choosing a "brand with R&D capabilities" - one that can solve practical problems and keep up with technological updates.   Ⅰ.Brands with strong R&D capabilities all have "hard tags"   Not all brands dare to claim they have R&D capabilities. The truly reliable ones all escape these four hard standards. Customers should remember these points and directly match them when choosing, and it will be correct every time.   1. Core patents as the foundation: Don't do "dummy patents", but have patents that can truly solve problems   The first step in R&D capability is to have something that can be showcased - not just a few appearance patents to pad the numbers, but practical patents that can solve industry pain points. For example, key technologies such as anti-interference, noise reduction, and automatic sensing, the more such patents there are, the more solid the brand's R&D foundation is.   2.Have an independent production system: Full control from R&D to production   Just having technology in the laboratory is not enough; being able to turn that technology into a stable and usable product is the real ability. Brands with R&D capabilities usually have their own production factories, being able to control the entire process - from R&D design, component purchase, to production assembly and quality inspection, all under their own control, avoiding "good results in the laboratory, but problems in mass production".   3.Can continuously iterate technology: Follow market demands   The industry is constantly changing, and so are the demands - such as multi-language support, global voltage compatibility, automatic sensing for scenic spots, and industrial-grade noise reduction for enterprises. Brands with strong R&D capabilities can quickly respond to these demands and launch new products, rather than having one product sell well for several years and ignoring market feedback.   4.Obtain all international certifications: Technology meets global standards   R&D capability is not something that can be blown out of the water; it must be recognized by international authoritative institutions. For example, EU CE, RoHS certification, China CMA, CNAS testing, having these certifications means that the product's technology, safety, and environmental protection meet global standards, which is also a "hard endorsement" of R&D strength.   Ⅱ.Yingmi's R&D hard strength: Works well from the laboratory to the global stage   The reason Yingmi was selected by international museum high-level forums, the SCO International Judicial Conference, and the Suzhou Taihu Scenic Area, etc., is mainly because it has concentrated its efforts on R&D for 18 years and has achieved the above four hard standards to the extreme. Its R&D is not "paper talk", but can truly solve customers' practical problems.   1. Specialized in R&D: National-level qualifications + real core patents   Since its establishment, Yingmi has been dedicated to R&D of audio guide devices. Now it is a national high-tech enterprise and a big data enterprise. Up to now, it has many utility model patents and computer software copyrights, and these core patents can solve industry pain points - such as "a multi-channel anti-interference wireless audio guide device system" and "location technology for intelligent sensing audio guide device", not "futile patent" for show purposes.   More importantly, Yingmi's R&D team is not a temporary assembly of people, but all veteran engineers in fields such as electronic engineering, software algorithms, and acoustic technology. It also invests a lot of money in R&D each year. Just in 2024, R&D investment accounted for more than 18% of sales, much higher than the industry average.   2.Core technology: Solving the difficulties of audio guide devices   The "H4 four major technical advantages" independently developed by Yingmi precisely address the core needs of domestic and foreign customers. Each item can show the R&D strength:   The first is the SOC embedded integrated digital filtering and noise reduction technology - it addresses the issue of unclear sound in noisy environments. Even in factory workshops or popular tourist attractions where it's noisy, this technology can filter out environmental noise and ensure that the ambient sounds are eliminated, allowing the audio to be heard clearly. The second is the PMU secure intelligent lithium battery power management technology - it specifically developed explosion-proof and long-lasting lithium batteries. For example, the E8 team's speaker system, the transmitter can last for over 18 hours, and the receiver can last for 8 to 10 hours, making it suitable for high-intensity use throughout the day. The third is the ERGO ergonomic design - considering that people will wear it for a long time, Yingmi developed an earpiece device weighing only 17g. After wearing it for a long time, the ears won't hurt, and it's also convenient to carry in a pocket. The fourth is the HM8.0 multilingual sharing platform - small language customization can be done, and the audio quality algorithm can be optimized to restore the pronunciation characteristics of the language, making it particularly suitable for international scenarios.   3.Own SMT factory: Research results not "lost"   Many brands have research and development technologies but no own production capacity. They have to outsource production to factories, which often leads to situations where "the results are good in the laboratory, but fail in mass production". Yingmi has already invested money to build its own SMT surface mount technology assembly factory (Hefei Speedy Electronics), achieving independent production of PCBA. From research and design, purchasing components, to production assembly and quality inspection, the entire process is controlled by itself, without having to follow others' instructions.   Every new product developed will go through five tests and six challenges in its own factory - tests such as high temperature, low temperature, vibration, and drop, all must be passed to ensure that the products produced in large quantities have the same quality as the laboratory samples. Take its i7 automatic sensing speaker system for example, during the research and development stage, the "precise positioning sensing" problem was overcome, and during production, strict quality control was carried out. After being sent to global tourist attractions in large quantities, the feedback was very good, saying that "the sensing accuracy rate is almost 100%".   III. Whether the research is good, you can tell from the product   Whether the research capability is good can ultimately be judged by how the product performs. Yingmi's two core products are the "living proof" of the research strength, particularly suitable for different scenarios of customers:   1. i7 automatic sensing speaker system: "Research good" for tourism scenarios   This is a "lightweight wonder" specifically made by Yingmi for scenic spots and museums. It weighs only 17g and has an integrated earpiece design, making it very comfortable to wear. The core highlight is its own-developed RFID intelligent positioning technology, with a sensing distance that is very accurate, ranging from 0.5 to 35 meters, and the explanations will automatically play when the tourists approach the scenic spot, neither too early nor too late; it can store 9999 explanations, and the language switching is very convenient, and it will automatically save the last used language and start with the usual language when turned on next time, without the need to repeatedly adjust.   What shows the research details even more is that it also has built-in low battery reminder, return reminder, and anti-theft alarm functions, solving the major problems of scenic area management; in addition, the digital noise reduction technology ensures that even in noisy tourist attractions, the explanations can be heard clearly. Now this product has been sold to many countries in Europe and Asia, becoming the preferred choice for many overseas tourist attractions.   2.E8 team presentation system: "Stable King" for high-end scenarios   For international conferences and enterprise visits of high-end scenarios, Yingmi developed the E8 team presentation system. The core is its own anti-interference technology and long battery life technology. It uses U-band high-frequency radio waves + 4GFSK signal modulation technology, which can open 200 independent channels, even if 100 teams use it together, there will be no interference; the communication distance can reach 200 meters, whether in large factories or open tourist attractions, the signal is very stable. The transmitter of its device can last for over 18 hours, and the receiver can last for 8 to 10 hours. When combined with Yingmi's own developed contact-type charging box, it can charge in batches quickly and safely, with an added ultraviolet disinfection function. It has been used for explanations at the International Judicial Conference of the Shanghai Cooperation Organization and the Bentley Automobile Exhibition. Throughout the process, there was no interference or interruption. This is precisely due to its solid research and development capabilities.   Ⅳ.To be honest: Choosing a research and development-oriented brand means choosing "long-term peace of mind".   For customers, purchasing a wireless audio guide device is not a one-time transaction. The subsequent adaptation, maintenance, and function upgrades all require the brand to support them. Yingmi's research and development capabilities not only ensure that it is easy to use now but also solve the subsequent concerns - for example, if customization for a minority language is needed, its R&D team can quickly optimize it; if it needs to be adapted to the local voltage, it has already prepared a wide-voltage module; if later on, the intelligent functions need to be upgraded, its technological iteration ability can also keep up.   There is no need to worry about "which brand has research and development capabilities". Yingmi's national-level qualifications, core patents, own factory, and global cases can all prove its research and development strength. Choosing it is not just buying a product; it is more like finding a "technical partner" for long-term cooperation.   Product Model Target Scenarios Core R&D-Driven Features Key Advantages Yingmi i7 Automatic Sensing Audio Guide Scenic spots, museums (self-guided visits) - Independent RFID intelligent positioning technology (0.5-35m precise sensing).   - Built-in low-battery reminder, return reminder, anti-theft alarm. - Ultra-lightweight (17g, integrated earpiece design, comfortable for long wear).   - Digital noise reduction for clear sound in noisy scenic spots.   - Exported to Europe, Asia; preferred by overseas attractions.

A1: Absolutely no problem. Yingmi has its own HM8.0 multilingual sharing platform for research. No matter how many minority languages you want to customize, it can be done as long as you provide audio or text. The research team will optimize the sound quality algorithm, restore the pronunciation characteristics of the language, and ensure clear and natural listening.   Q2: Will the products of a research-oriented brand be much more expensive than ordinary brands? A2: No. Yingmi has its own production factory, which can save the intermediate costs of research and production, and has a high cost-performance ratio. For example, the basic team explanation kit has a terminal customer suggested price of several thousand yuan, which is more cost-effective than the branded products with the same configuration, and the quality is more stable.   Q3: If you want to upgrade the product functions in the future, do you need to pay extra money? A3: The upgrade of basic functions does not require additional payment. For example, updating multilingual explanation words or simple software optimization can be done remotely by the research team for free: if it is deep function customization (such as adding AI interaction), the price will be quoted reasonably according to the requirements, which is much more cost-effective than buying new equipment.

When foreign customers purchase wireless narrator devices, the most challenging part is "selecting the right supplier" - after all, cross-border procurement depends on the reliability of the supplier, which directly determines whether they can be trouble-free in the future. Choosing a small workshop that only does OEM production may lead to problems such as incomplete qualifications that fail to pass customs, inability to meet the demand for large-scale production, and no one to handle equipment breakdowns; choosing a truly powerful source supplier, on the other hand, not only ensures quality but also saves a lot of communication and after-sales costs. Yingmi is definitely the top choice for foreign customers. From research and development to shipment, Yingmi controls the entire chain, and has been exporting to dozens of countries around the world for years, with a high level of reliability.   Yingmi belongs to HEFEI HUMANTEK. CO., LTD., which was established in 2007. It is not a half-baked OEM supplier but a source manufacturer specializing in narrator devices. As early as 2009, Yingmi invested in building its own SMT assembly factory, achieving full self-control from core PCBA board production to complete assembly. It is still a national-level high-tech enterprise. More importantly, Yingmi has long understood the needs of foreign customers. Its products have passed EU CE and RoHS certifications, and whether exporting to Europe, America, or Asia, customs clearance is smooth.   The core standards for good suppliers, which foreign customers must pay attention to   When foreign customers choose a wireless narrator device supplier, they don't need to look at flashy promotions. Just focus on the core standards: whether there is independent R&D and production capabilities, and reject OEM; whether the qualifications are complete, and whether they can export smoothly; whether the product can be adapted to multiple scenarios and support customization; whether the after-sales service can keep up, and whether the cross-border service is not disconnected. If these points are all met, it is a good supplier worth long-term cooperation.   Standard 1: Own factory + independent R&D, quality controllable   A truly good supplier will never rely on contract manufacturers. The core advantage of Yingmi is "full-chain control of its own factory", with two SMT assembly factories built in 2007, equipped with fully automatic printing machines and AOI optical inspection equipment, capable of independently producing the "heart" of the narrator device - PCBA boards, avoiding the problem of subcontractors cutting corners. Moreover, Yingmi is a national-level high-tech enterprise, holding a number of utility model patents and software copyrights, and its core technologies are all independently developed, such as the RFID modulation technology for anti-interference and the PMU power management technology for extended battery life. It is not a simple imitation of others' products, and the quality and stability are more guaranteed.   Standard 2: Complete qualifications, no compliance risks in export   When foreign customers are worried about "incomplete qualifications failing customs clearance", good suppliers must solve compliance issues in advance. Yingmi not only passed ISO9001, 4001 three-party certifications, but also obtained EU CE, RoHS certifications for all exported products, as well as Chinese CMA, CNAS dual testing reports. These certifications were not done through third-party agencies, but were actually passed based on the production process and quality control system of its own factory. Now it has been exporting to dozens of countries around the world for years, and has never encountered any problems due to qualification issues.   Standard 3: Complete product matrix, support customization for multiple scenarios   The requirements for narrator devices vary in different scenarios. Good suppliers must have a rich product matrix and be able to support customization. Yingmi covers all scenarios such as team narration, self-service guidance, and area narration, and can find suitable products for everything from scenic area team reception, museum self-service visits, to VIP reception in enterprise exhibition halls. More importantly, Yingmi offers customization services - such as customizing equipment with brand LOGO for enterprise exhibition halls, waterproof and sunproof sensing labels for outdoor scenic areas, and multi-language narration content for multinational customers. These can precisely meet special needs.   Why is Yingmi the top choice for foreign customers? It all depends on the strong capabilities   Yingmi has been able to consistently rank high on the purchase lists of foreign customers not by chance, but by meeting the needs of foreign customers at every step, from research and development, production to service. They truly achieved the goal of "one-time cooperation, worry-free for many years".   The seamless connection between R&D and production, and stable batch supply   Yingmi's R&D team and production team are in the same park, and the efficiency of technology implementation is extremely high. For example, when foreign customers requested "a more lightweight self-service guide machine", after the R&D team determined the solution, the production team could adjust the production line on the same day and quickly produce samples. The batch production cycle was also short - for regular orders, it could be delivered within 7-10 days, and for customized orders, it could be completed within 15-20 days. Now, Yingmi has 4 automated production lines, with a monthly production capacity of over 20,000 units. Even for large orders of thousands of units, they can be delivered on time without any "delivery delay" issues.   The product details are fully packed, suitable for global scenarios   Yingmi's products have already undergone tests in different global scenarios: in the high-temperature and high-humidity scenic areas of Laos, the equipment can operate stably; in the multi-language museums in Europe, it supports the storage of multiple explanation words and is compatible with minority languages; in large international conferences, the anti-interference technology can ensure that multiple teams can use it simultaneously without interference. Moreover, the product details are particularly thoughtful, such as the sensing labels supporting multiple numbers, which can match each exhibit in the museum; the charging box has an ultraviolet disinfection function, which complies with foreign hygiene standards; the equipment weight is generally controlled within 50g, making it comfortable to wear without causing pressure on the body.   Precise selection for different scenarios, these two products are worth choosing without hesitation   Yingmi's product portfolio is very comprehensive.

When many foreign customers purchase wireless narrators, they all have a common confusion: among so many brands, which one truly has market competitiveness? Choosing a small brand either doesn't fit the rules of the overseas market and the customs clearance is troublesome; or the product breaks down within half a year and the after-sales service is hard to find; or the product can't meet the scene requirements and wastes costs.   Judging the competitiveness of a brand is impossible without all the core dimensions.   For foreign customers, choosing a competitive brand of wireless narrators doesn't require blind comparison. Focus on these points and you can quickly screen out reliable options.   1. Overseas market adaptability - Can it smoothly "enter" the market?   This is the most basic competitiveness. The brand must understand the rules of the overseas market, such as having to pass the certification of the target region (like EU CE, RoHS), and the product must support multiple languages and be compatible with the local voltage. If these are not achieved, even if it is cheap, it won't be useful, and customs clearance will be blocked, and the subsequent use will also be troublesome.   2.Full-chain self-strength - Can the production capacity and quality be stable?   Competitive brands will never rely on assembly by contract manufacturers. Only by building your own production line and controlling the production of core components can you ensure stable production capacity (no delays in large-scale purchases) and controllable quality (no batch failures). Small brands rely on contract manufacturers, not only will their production capacity be limited, but the quality control also depends on the factory, and it can't be said to be competitive at all.   3.Core technology and quality control - Can the product be "used long and well"   The core of the wireless narrator is "clear, stable, and resistant to interference". Competitive brands have their own core technologies, such as noise reduction and interference resistance technologies; they also have strict quality control systems to ensure that the equipment can operate stably in different scenarios such as high temperature and humidity. This directly determines the user experience and lifespan of the product.   4.Service and cases - Can there be "no worries" in the future   Overseas purchasing is most afraid of a lack of after-sales service. Competitive brands have a complete overseas service system, such as remote technical guidance and cross-border repair support; at the same time, they have a rich history of overseas cases, proving that the product can be adapted to different countries' scenarios, which is also the best endorsement of strength.   The core competitiveness of Yingmi: Full pull through from overseas adaptability to service Yingmi belongs to HEFEI HUMANTEK. CO., LTD. It was established in 2007 and has been dedicated to making narrators for 18 years. It has been able to establish a foothold in the global market by achieving all the above competitiveness to the extreme.   Competitiveness 1: Deeply adapt to the overseas market, and customs clearance and use are hassle-free   Yingmi has long understood the rules of the overseas market. All wireless narrators have passed the EU CE, RoHS environmental protection certifications, as well as domestic CMA, CNAS dual testing certifications. They can smoothly clear customs and export to dozens of countries in Europe, Southeast Asia, and America. For different voltage standards in different countries (such as 110V and 220V), custom-made charging equipment can be customized, and no additional modification is needed.   Multilingual support is also well in place. The M7, C7, etc. models of Yingmi support more than 8 languages for switching and can be customized for small languages, with the ability to store multiple segments of explanations, which is sufficient for receiving international tourists or serving people of different languages in local areas. Many overseas scenic spots have reported that Yingmi's multilingual function is more accurate and stable than many of its competitors.   Competitiveness 2: Core technology + strict quality control, product strength is resilient   Yingmi has 4 core patent technologies, such as SOC embedded integrated digital filtering, noise reduction technology, which can effectively filter the environmental noise in scenic spots and exhibition halls, making the narrator sound purer; The PMU secure intelligent lithium battery power management technology not only enables devices to have a longer battery life (the self-guided tour machine can work for at least 10 hours, and the team guide device can remain on standby for over 11 hours), but also has explosion-proof features, allowing it to be used with confidence in complex environments.   The quality control is even more stringent, adopting the 7S product quality control system. Each device undergoes 5 strict inspections from component entry to finished product production - signal stability, noise reduction effect, high and low temperature adaptability, battery life, etc., all must pass. Just like the Xiangkun Temple scenic area in Vientiane, located in the tropics with high humidity and rainfall, Yingmi's self-guided explanation equipment has been installed for several years and still operates stably without any major failures.   Competitiveness 3: Complete overseas services + rich cases, with strong after-sales support   Yingmi's "9G full life cycle service" has a good reputation among overseas customers: pre-sales response within 90 seconds, free sample testing can be provided, and 1000+ real cases can be referenced; during the middle sales process, on-site investigation of the site can be conducted (local teams can be coordinated for overseas large customers), and urgent orders can be dispatched on the same day; after-sales support provides remote technical guidance, and if on-site maintenance is needed, cross-border services can be coordinated. Previously, Yingmi has provided cross-border installation and maintenance for the Xiangkun Temple scenic area in Vientiane.   In terms of cases, it is even more outstanding. Yingmi has served high-level international museum forums, the highest judicial conference of the Shanghai Cooperation Organization, and has provided equipment to multiple scenic areas and museums in France, Germany, Malaysia, etc. Globally, it has served over 7,000 customers. These cases are proof of strength and also make overseas customers more confident in purchasing.   Core product recommendation, covering mainstream overseas usage scenarios   Based on the common needs of overseas customers, two competitive products from Yingmi are recommended, which can be adapted to both scenic area team reception and individual tourist services.   Recommendation 1: K8 Team Guide System - The preferred choice for overseas scenic areas and enterprises   This product is particularly suitable for overseas scenic areas, enterprise exhibition halls, and government receptions. It adopts an ear-catching integrated design without ear insertion, with a receiver weight of only 22 grams. Tourists won't feel tired after wearing it for a whole day. The non-ear-insertion design is also more hygienic, avoiding the risk of multiple people sharing.   The core advantages are highly compatible with overseas scenarios: using the 790-830 MHz high-frequency band for transmission, with extremely strong anti-interference capabilities, even if multiple teams are giving explanations in the scenic area at the same time, they can each give their own explanations without interference; the automatic frequency synchronization function allows tourists to use the device immediately after turning it on without manual channel adjustment, saving the guide's time; after charging, it can be used continuously for 7-8 hours, meeting the needs of all-day reception; the touch charging box is made of metal, safe without fire hazards, and can charge and store multiple devices at once, making management convenient.   It has passed a complete set of international certifications, supports multilingual explanations, and can customize logos and packaging according to overseas customer needs. Many overseas scenic areas have reported that this device's durability and stability are much better than competing products at the same price.   Recommendation 2: M7C Self-guided Sensing Tour Machine - A must-have for overseas independent travelers   If the overseas scenic area is mainly for independent travelers, this self-guided tour machine is definitely a must-have. It adopts the RFID-2.4G star distribution system design, supporting automatic sensing and NFC point touch modes: when tourists approach in areas with long distances, the explanation will be automatically played; in exhibition halls with dense exhibits, touching the tag can accurately listen, without any sensing interference.   The highlights for overseas adaptation: supports 8 language switches, automatically restoring the last selected language when the device is turned on next time, making it convenient for foreign tourists to use; the chest-worn design is very lightweight, not tiring after wearing for a whole day, with durable power, and no problem with all-day touring; it can store multiple explanations, whether it's the history, legends of the scenic area, or folk culture, it can provide detailed explanations. It has also obtained the EU CE and RoHS certifications, making the export clearance process stress-free. Currently, it has been put into use in multiple scenic areas in Southeast Asia.   FAQ   1. Can Yingmi Speaker Adapter be compatible with different voltage and plug standards in various overseas countries? Answer: Yes.

Many customers have fallen into the "incompliant certification" trap when purchasing wireless audio guide devices - either the products couldn't pass customs when delivered to the local area, or they were found to not meet environmental or safety standards when used, and in the end, they had to return and rework, incurring significant losses. To be honest, for customers, choosing a wireless audio guide device should start with checking the "quality certification", as this is not only the "passport" for export but also a "calming factor" for product quality.   What customers must know: Quality certification is the essential threshold   The first type: International basic certifications - To export smoothly, these two certificates are the bottom line.   This is the most basic and crucial certification, directly determining whether the product can enter the target market. For example, to export to Europe, CE safety certification and RoHS environmental protection certification must be present; the former ensures safety when used, and the latter limits harmful substances in the product; if exporting to other regions, it must also comply with the corresponding basic standards in the local area. Without these certifications, the product simply cannot pass customs, let alone be sold or used locally.   The second type: Quality inspection certification - Whether the product is durable depends on this   Basic certification is just the entry point; the quality and usability of the product also depend on professional inspection certification. For example, the CMA metrology certification and CNAS laboratory accreditation in China, these two certifications have strict requirements for the signal stability, noise reduction effect, and battery life of the product, and even its performance in high and low temperature environments. Products that pass these certifications generally have good quality. Especially in scenarios with high frequency usage such as scenic spots and museums, the durability of the equipment directly affects the subsequent costs.   The third type: Industry qualification certification - Whether the brand is reliable can be known by this   In addition to the product's own certification, the brand's industry qualifications can also reflect its strength from an indirect perspective. For example, national high-tech enterprises, ISO9001 quality management system certification, and ISO4001 environmental management system certification. These qualifications are not easily obtained; brands must meet high standards in every step of research and development, production, and quality control, and small workshops simply cannot achieve this. Choosing a brand with such qualifications ensures more stable supply and after-sales services.   Yingmi: Comprehensive certification and strict quality control, quality can withstand global inspection   Yingmi is a brand under Hefei Weima Information Technology. Since its establishment in 2007, it has been dedicated to making audio guide devices for 18 years and has long been engaged in foreign trade business. It is particularly clear about the strict requirements for certification in the market. Now, Yingmi not only has all the basic international certifications but also a bunch of high-end industry qualifications. Many customers include international museum forums and SCO meetings of this high-end occasion.   Comprehensive core certification, no obstacles in export   All wireless audio guide devices under Yingmi have successfully obtained the EU CE certification and RoHS environmental protection certification, meeting the requirements of the European market; at the same time, they have also passed the domestic CMA and CNAS dual inspections, and the quality can withstand professional institutions' criticism. Due to the comprehensive certification, Yingmi's products have been able to smoothly sell to dozens of countries such as France, Germany, Malaysia, and Indonesia, with no customs clearance issues and good customer feedback.   What is even more remarkable is that Yingmi has also passed ISO9001 quality management system and ISO4001 environmental management system certifications, and it is also a national high-tech enterprise and a big data enterprise. These qualifications are not bought with money; behind them is Yingmi's strict control at every step of research and development, production, and quality control, which gives customers more peace of mind when purchasing.   Certification is not just for show: 7S quality control + core technology, this is the solid support   Yingmi's certification is not just for show; it is supported by a solid quality control system and core technology. The company has established a strict 7S quality control process. From the time the parts are warehoused to the time the finished products are manufactured and shipped out, each piece of equipment must pass at least five tests - checking the stability of the signal, the effectiveness of noise reduction, the battery life, and whether it can withstand high and low temperature environments. All these aspects must be tested to ensure that the equipment can operate stably in any environment, whether it is the hot and humid conditions of a scenic area or the enclosed environment of a museum.   There are also its own technical features. Yingmi has several independent patents. For example, the SOC embedded integrated digital filtering and noise reduction technology can filter out environmental noise completely, making the explanation sound clearer. There is also the PMU safe intelligent lithium battery power management technology, which not only has a long battery life but also is explosion-proof, making it safer to use. These technologies, combined with strict quality control, ensure that Yingmi's products not only "meet the certification standards", but also perform better in practice than expected.   Two high-compatible products are recommended, covering most usage scenarios.   Based on the common needs of customers, we recommend Yingmi's two certified products that are easy to use and suitable for most scenarios, whether it is for scenic areas, museums, or corporate receptions.   Recommendation 1: 007B Automatic Induction Interpretation System - Closed-eye Entry for Scenic Areas/Museums   This is Yingmi's classic model, specially designed for scenic areas and museums. It has all the necessary certifications such as CE, RoHS, CMA, and CNAS. Well-known scenic areas and museums like Gulangyu in Xiamen and Henan Museum are all using it. It uses RFID modulation technology and digital on-demand mode, with extremely strong anti-interference capabilities. Tourists can carry the device into the scenic area and, without manual operation, it will automatically play the explanation at the corresponding scenic spot as they walk to it.   The advantages are very practical: a 2.8-inch true-color screen, combined with high-definition built-in speakers, can be easily used by the elderly and children; it supports eight languages for display, and if other languages are needed, they can be added in advance, making it completely problem-free for receiving international tourists; the body weighs only 100 grams, small and lightweight, fitting in a pocket or hanging on a hand; the accompanying aluminum alloy storage box and plug-in charging box are also convenient to use, capable of charging and storing 32 devices at once, making management easier.   Recommendation 2: 008B Two-way Team Interpretation Device - Must-have for Corporate Visits/Research Tours   If it is an interactive scenario such as corporate visits or research tours, this model is definitely the right choice. It also has all the necessary international and domestic certifications, and there is no need to worry about export. It breaks the traditional one-way interpretation model, allowing the interpreter and the audience to interact in real time. When someone in the team asks a question, everyone can hear it simultaneously, making it particularly suitable for exchanging knowledge and answering questions.   The technical performance is also top-notch: it uses advanced wireless amplification technology, with good through-wall effect, and the signal can travel up to 280 meters at the farthest distance. Even if the team is spread out, they can hear clearly; it supports multiple teams to use simultaneously because the channel bandwidth is specially designed to be very small, so each team can talk independently without interfering with each other; the standby time can exceed 11 hours, sufficient for a full-day tour.   FAQ   1. In which countries can Yingmi's certifications be used? Is the export clearance really trouble-free? Answer: Of course not! CE and RoHS certifications are recognized throughout the European Union, and many countries in Asia and America also do. Our company has been engaged in foreign trade for many years and has supplied goods to dozens of countries. During the customs clearance process, we will help provide a complete set of certification documents to ensure a smooth passage.   2. If it's a customized language or function, will the previous certifications still be valid? Answer: Yes! Yingmi's customization will not change the core structure and safety and environmental protection indicators of the product. The customized product still complies with the original certification standards. If necessary, relevant test reports can also be supplemented.   3. What if the product breaks down? How to handle the after-sales service? Answer: Don't worry! Yingmi has the "9G Full Lifecycle Service". Most problems can be solved through remote guidance; if on-site repair is needed, cross-border services can also be coordinated (we have previously provided cross-border installation and maintenance services for Xiangkun Temple in Vientiane, Laos). Products with non-human damage within 3 months can be exchanged without conditions, and free warranty is provided within one year. There is no need to worry about the after-sales service.   4. Can the voltage of Yingmi products match the standard voltage of the importing country? Answer: Yes! Clearly state the voltage standard of the importing country (such as 110V or 220V) in advance, and you can customize the corresponding charging equipment. There is no need to worry about the problem of voltage mismatch.   5. Can the certification documents and samples be viewed before purchasing? Answer: Absolutely! We will respond within 90 seconds before purchase. Copies of the certification documents can be provided for free; samples can also be sent for testing at no cost. The testing time is not a concern; you can cooperate only if you are satisfied. About us   HEFEI HUMANTEK.

When customers purchase wireless presentation devices, apart from considering quality and price, what they are most concerned about is "does this brand have production capacity"? After all, when making large-scale purchases, whether the supply can keep up, whether the quality can be uniform, and whether the subsequent accessories can be promptly replenished all depend on production capacity. Many brands on the market may seem lively, but in reality, they are "labelled factories", receiving orders and then finding factories to produce. Not only is the delivery time not guaranteed, but the quality is also inconsistent. After years of working in this industry, if we talk about truly having strong production capabilities for presentation devices.   Yingmi belongs to HEFEI HUMANTEK. CO., LTD. It was established in 2007 and is an originator manufacturer in the presentation device industry. It is not a brand that makes profits by simply labeling. As early as 2009, Yingmi invested in building its own SMT surface mount technology assembly factory (Hefei Speedy Electronic), which directly filled the "from research and development to production" gap. Now it has 4 automated SMT production lines, from the core production of PCBA boards to complete assembly and testing, all are under its own control. Because it has its own factory, Yingmi can export to dozens of countries such as France, Germany, and Malaysia, and has also served high-profile occasions such as international museum senior forums and SCO meetings. Its production capacity and quality control have been tested in the global market.   A brand with production capacity   When customers judge whether a brand has production capacity, they don't need to look at flashy promotions. Just focus on the key points: does it have its own factory and core production line; is the research and development independent and can it be implemented in production; does it have a complete quality control system; can large-scale orders be responded to quickly and supply be stable. If these points are met, it is truly a brand with production strength.   Key 1: Own factory + core production line, reject reliance on label factories   A brand with true production capacity will never rely on label factories. The core advantage of Yingmi is "full-chain control of its own factory", the SMT surface mount technology assembly factory it built in 2009 was equipped with fully automatic printing machines and AOI optical detection equipment, capable of independently producing the core components of presentation devices - PCBA boards - which are the "heart" of presentation devices. Independent production can control the quality from the source and also be flexible in adjusting production capacity. Now Yingmi's factory can achieve the entire production process from chip welding, component assembly, to finished product testing and packaging, with 4 automated production lines, with a monthly production capacity of over 20,000 units. Even large orders from customers can be responded to quickly.   Key 2: Independent research and development, technology can be directly implemented in production   Production capacity is not "just assembly", it also needs to be able to implement independently developed technologies. Yingmi is a national-level high-tech enterprise, holding several utility model patents and computer software copyrights. The core technologies are all independently developed, such as SOC embedded integrated digital noise reduction technology, PMU safe intelligent lithium battery power management technology. These technologies are not just on paper, but can be accurately transformed into products through its own factory.   Key 3: Strict quality control system, each device passes "multiple tests"   A brand with strong production capabilities must have a complete quality control system - after all, in large-scale production, quality consistency is more important than anything else. Yingmi implements the 7S quality control system, and before each presentation device leaves the factory, it must undergo 5 tests: signal stability test, battery life test, anti-interference ability test, wear resistance and drop test, as well as high and low temperature environment test. For products exported to Europe, additional tests such as CE and RoHS certification related tests must be conducted to ensure compliance with international standards. Such strict quality control can only be achieved by having your own factory. Most contract factories merely follow a simple assembly process and cannot achieve full-process inspection.   Yingmi's production strength: From R&D to shipment, everything is under its own control.   Yingmi's ability to establish a firm foothold in the global market is due to its "production capacity without compromise". From the R&D laboratory to the production line and then to the shipping warehouse, every step is controlled by itself. This is the core reason why customers are willing to cooperate long-term.   Self-owned factory as a guarantee, flexible production capacity adjustment   Yingmi's SMT factory not only can produce PCBA boards but also can achieve integrated production of complete machines. It does not rely on external suppliers. For example, during peak production periods, the factory can immediately add production lines, with a maximum monthly production capacity of up to 30,000 units; when facing small-batch customized orders, it can flexibly adjust the production plan without refusing or delaying due to small order quantities. This flexible production capacity adjustment ability is something that contract factory models' brands simply cannot match - most contract factories only accept large-batch orders, and small-batch customization not only has high prices but also no guarantee of delivery time.   Full qualifications support, no pressure for exports worldwide   A brand with production capacity can surely handle the compliance requirements of different countries smoothly. Yingmi has obtained ISO9001, 4001 three certifications, and all exported products can obtain EU CE, RoHS certifications, as well as Chinese CMA, CNAS dual testing reports. These certifications are not done by third-party agencies but are based on the production process and quality control system of the self-owned factory, which are actually passed. Therefore, when products are exported to any country in the world, they can smoothly pass customs inspections without any compliance issues.   High cost-effectiveness choice: Stable and good products supported by production strength   Yingmi, with the advantage of its self-owned factory, has created multiple audio guides suitable for different scenarios, especially these two models, with production processes and quality control fully optimized, making them particularly suitable for large-scale purchases by customers.   Team reception preferred choice: L8 team audio guide system, more convenient for large-scale use   L8 is specially designed by Yingmi for team scenarios such as scenic spots and conferences. It becomes a hit due to the precise production control of the self-owned factory. It uses the UHF663-694 MHz high-frequency band, has strong anti-interference capabilities, supports 102 channel adjustment, and even when 20 teams are using it simultaneously, there is no interference - this is due to Yingmi's self-developed digital anti-interference technology, combined with the strict quality control of the factory for chip soldering, to achieve stable transmission.   Production details reveal strength: The L8 transmitter weighs only 48g, and the receiver weighs 16g. The body uses high-strength lightweight materials, this "light and durable" balance was achieved through repeated testing of materials and molds by the factory; the charging box is made of all-aluminum material, with built-in silicone grooves, which can precisely fit each device, and this is also customized by the self-owned factory for batch production, with extremely high quality consistency. More importantly, the L8 can last for more than 8 hours, and the lithium battery used is assembled by the factory from purchased cells, ensuring safety and stable battery life. Whether it is large-scale procurement by scenic spots or long-term use by conference companies, you can place orders with confidence.   Outdoor/long-distance preferred choice: 008A ear-mounted audio guide, durable and sturdy   If you need long-distance outdoor guidance, 008A is definitely the first choice. Its production process fully complies with industrial standards. 008A uses a 935 MHz - 955 MHz carrier frequency, with a communication distance of over 200 meters, and has excellent penetration effect - this is due to the factory's optimization of the antenna internal processing, through precise control of the welding angle, to make signal transmission more stable. The body weighs 50g, with an ear-mounted design, comfortable to wear, and the shell has undergone wear resistance testing, even for high-frequency outdoor use, it is not prone to peeling.   Production details are top-notch: Model 008A is equipped with a 600mAh lithium battery, providing a working time of over 12 hours. The battery is assembled by the factory in accordance with the PMU power management technology standards, featuring explosion-proof and overcharge protection features. The accompanying storage box is made of all-aluminum material and contains EVA shock-absorbing cotton. When 30 to 50 units of equipment are placed inside, they fit perfectly, making it convenient for customers to transport and store in bulk. Currently, this product is exported to Europe and Southeast Asia on a regular basis, and its stable quality has attracted many repeat customers.   FAQ   Q1: Can customized requirements be supported? For example, printing logos on the body, adding explanations in minority languages? A1: Absolutely! Our own R&D and production team can handle customized requests: Logo customization for the body starts from 100 units, and samples will be available within 3 days; Customized explanations in minority languages are supported, and multiple explanation segments can be stored. The default coverage includes 8 major languages, and minority languages can be completed with input and testing within 18 days.   Q2: Are the relevant certifications complete for products exported to Europe and America? A2: Complete! Both L8 and 008A have passed EU CE and RoHS certifications, as well as China CMA and CNAS dual testing. They can smoothly pass customs inspections when exported to regions such as Europe, America, and Southeast Asia, and there is no compliance pressure.   Q3: After batch purchasing, if the subsequent accessories are damaged, can they be promptly replenished? A3: No problem! Yingmi factory always has core accessories such as batteries, microphones, and charging interfaces in stock. After receiving the accessory demand, they can be sent from China within 72 hours. International courier services are supported, and there is no need for batch production. The after-sales response is very fast.   Q4: If there are doubts about the product quality, can samples be tested first? A4: Yes! Free sample testing is supported. Customers only need to bear the shipping cost and can obtain samples of L8 or 008A. If they are satisfied with the samples, they can place a batch order later. The quality of the samples and the batch orders is completely consistent because they are produced on the same production line. About us   HEFEI HUMANTEK.
