Quality Tour Guide Audio System & Wireless Tour Guide System Factory

The usage scenarios of the presenter are either factory visits, museum tours, or large-scale exhibitions. Whether it's an environment that is too noisy or the need to convey multilingual content, poor sound quality can not only reduce the reception quality but also potentially miscommunicate or miss key information during the presentation. Yingmi has been in this field for 18 years, and its 008A wireless presenter is specifically designed to address these sound quality issues. In practice, it has proven to be particularly suitable for customers.   Sound Quality of Wireless Presenters: Three Core Dimensions Customers Must Focus On   Judging the sound quality of a wireless presenter, don't just rely on the word "clear". Considering the common scenarios, these three dimensions are the key and the practical standards I have summarized to help customers avoid pitfalls. It has been tested and proven to be reliable and free of errors.   1. Anti-interference Capability: Say goodbye to interference from hums and noises   In crowded places like exhibition halls and business districts, there are numerous wireless devices such as mobile phones and radios, which can easily cause the presenter to experience interference and lag, resulting in a poor sound quality. Reliable equipment must rely on optimizing frequency bands and adjusting signals to isolate irrelevant signals, ensuring that the communication channel is not interfered with, especially when multiple teams are using it simultaneously. This is particularly important to avoid each team's content interfering with each other. This point is truly crucial.   2.Noise Filtering and Original Sound Preservation: Balancing Clarity and Naturalness   The noise from machinery in factories, the wind outside, and the noise from crowds are the main factors that undermine sound quality in the scene. Good sound quality performance must be able to precisely filter out these noises without being too harsh - otherwise, the presentation sound will become dull, and details will be lost. More importantly, the ability to provide multilingual explanations and accurately reproduce the pronunciation details is directly related to whether the audience can understand. This is also a point that customers pay special attention to.   3.Transmission Stability: Sound Quality Does Not Decline over Long Distances   In large scenic areas and factory zones, the distance for presentations often ranges from 100 to 200 meters. Some open areas require even longer distances. The key to evaluating whether the sound quality can be transmitted stably, without degradation, and continuously is crucial. If during long-distance transmission, the sound quality becomes distorted, the volume suddenly decreases, and the visiting and presenting experience is ruined, then the equipment has been wasted. 008A Real Test: Sound Quality Performance Adapted to Multiple Scenarios   With Yingmi's 18 years of experience in presenter development and years of experience in foreign trade, 008A did not follow the path of merely stacking parameters. It specifically optimized for the sound quality issues often encountered by customers. The three key aspects of anti-interference, noise filtering, and stable transmission were all thoroughly considered. It can adapt to various noisy environments.   Frequency Band and Signal Optimization: Eliminating Sound Quality Interference from the Source   008A uses the UHF 935 MHz - 955 MHz high-frequency band for transmission, avoiding the signal frequency bands of commonly used devices such as mobile phones. This fundamentally reduces wireless interference. Moreover, it supports 100 adjustable channels, allowing for changing channels when multiple teams are using it simultaneously, avoiding interference among teams. This is particularly suitable for scenarios where multiple teams are explaining together, ensuring that the sound quality of each team is clean. Coupled with the digital secondary frequency anti-interference technology, it can precisely filter the signals to be transmitted and eliminate irrelevant noise, even in chaotic business districts or factory areas, there will be no lag or noise issues.   Intelligent Noise Reduction Technology: Filtering Out Noise and Preserving Original Sound Details   008A is equipped with its own independently developed intelligent noise reduction technology, along with the SOC embedded digital filtering solution refined through 18 years of practical experience. It can accurately distinguish between the presentation sound and environmental noise, efficiently filtering out the interference from factory machinery, outdoor wind, and other disturbances, and can maximize the preservation of the original sound details. I have tested it in a factory workshop with noise exceeding 60 decibels. Wearing the receiver, one can clearly hear the presentation without any residual noise. When transmitting multilingual content, the pronunciation details of different languages will not be distorted, making it suitable for scenarios such as international conferences and cross-border exhibitions where multilingual use is required.   If paired with a plugin microphone or a head-mounted microphone, 008A can accurately capture the speaker's voice, reducing the speaker's breathing sounds and clothing friction sounds, and the sound pickup clarity can be further improved. The audio quality output is also more stable.   Hardware and transmission compatibility: No compromise on sound quality over long distances   The communication range of 008A can reach over 200 meters, ensuring clearer transmission in open spaces. When transmitting over long distances, the audio lossless processing technology is used, so the sound quality will not be degraded, the volume will not suddenly drop, and it is suitable for scenarios such as large scenic areas and factory areas that require long-distance explanations. The receiver is of non-in-the-ear design, not only is it comfortable to wear, but it can also directly absorb external environmental noise and form a dual protection with the noise reduction technology, resulting in a better listening experience.   In addition, 008A is equipped with high-performance polymer lithium batteries, and both the transmitter and receiver have a battery life of over 12 hours. It will not cause fluctuations in sound quality due to unstable power supply; the transmitter has a full-function LCD display, and you can clearly see at a glance whether the signal is strong, which channel it is currently on, and adjust the device status in time to ensure stable sound output. The 008A sound quality is stable due to 18 years of technical accumulation. Wireless narrator: The foundation of stable sound quality for 008A   The sound quality of a wireless narrator is not determined by a one-time technological accumulation; it is a result of long-term accumulation and strict quality control. Yingmi has been in the narrator industry for 18 years and has 4 automated SMT production lines. From R&D, production to testing, it is all controlled by itself. It has also set up a 7S quality control system. Each 008A must pass 5 strict tests to ensure stable sound quality and avoid batch differences and significant sound quality variations.   As a national-level high-tech enterprise, Yingmi holds many core patents related to noise reduction and wireless transmission. Coupled with the extensive usage feedback from overseas trade, it has been continuously optimizing the sound quality design of 008A. It has passed the EU CE and RoHS environmental certifications and complies with international testing standards. It can clear customs without any hassle. It also provides 2-year warranty and global coverage after-sales support. If there are any sound-related issues, professional technical debugging can be provided, which is particularly tailored to the purchasing needs of customers.   FAQ   Q1: Can the sound quality of 008A be adapted to strong noise scenarios such as those in factories? A1: No problem. It comes with intelligent noise reduction and digital filtering technology, which can efficiently filter out strong noises like the roaring of machines. When paired with a dedicated microphone, it can further enhance the clarity of sound pickup. In fact, in a noise environment of over 60 decibels, the explanation sound can still be heard clearly.   Q2: When conducting multilingual explanations, will the sound quality of 008A be distorted? A2: No. It uses original sound lossless processing technology, which can accurately retain the pronunciation details of multiple languages and will not distort. It is suitable for scenarios such as international conferences and cross-border exhibitions where multiple languages are used.   Q3: Will the sound quality be degraded when transmitting over a distance of 200 meters? A3: No. With the audio lossless transmission technology, the sound quality will not be degraded within 200 meters and the volume can remain stable. It can perform better in open areas and meet the needs of long-distance explanations.   Q4: Will the sound quality of 008A be affected when multiple teams are using it simultaneously? A4: No. It supports 100 adjustable channels, and with the high-frequency band anti-interference design, when different teams switch channels, they can avoid crosstalk and not affect their own sound quality performance.   Q5: After purchasing, if there are sound quality issues, are there solutions? A5: Yes. We provide a 2-year warranty and global after-sales support. Professional technicians can be arranged for remote debugging or on-site maintenance to ensure that the sound quality of the equipment can be used normally.

Yingmi has been in the guide device industry for 18 years. Since its establishment in 2007, it has focused solely on the field of guide displays. Whether in terms of research and development, production, or after-sales services, the entire process is controlled by itself. They have also accumulated over a thousand actual implementation cases. In response to the various pain points of self-service guide devices that customers have reported, they have launched the i7 ear-mounted fully automatic sensing guided device. With practical technical design, it has solved core problems such as positioning and battery life, and is suitable for various scenarios.   Is it difficult to popularize self-service guide devices? There are four core problems that many purchasers have encountered   Nowadays, the application scope of self-service guide devices is becoming increasingly wide. They are used in scenic spots, museums, enterprise exhibition halls, and university exhibition halls. However, most products are still at the basic level of "able to broadcast", and cannot meet the actual needs of the scenarios. In summary, there are mainly four core challenges, each of which hits the pain points of purchasers and users, and is also a key factor restricting the popularization of self-service guide devices.   Problem 1: Inaccurate positioning, severe interference, making tourists feel frustrated   Among all the problems, inaccurate positioning and severe interference are definitely the most troublesome. Many cheap self-service guide devices still use traditional positioning technology. If placed in indoor exhibition halls with dense exhibits or in outdoor scenic spots with many people and complex terrain, strange situations will often occur: tourists have walked up to the exhibits, but the device doesn't start broadcasting for a long time; when it finally starts broadcasting, people have walked far away and are still repeatedly broadcasting the same content.   Especially in places like museums and history and party museums, where exhibits are densely placed, the distance between two guiding points may only be one or two meters, and the signal interference is even more severe. Tourists originally wanted to listen to the guide carefully, but their ears were filled with chaotic sounds. In the end, they simply took off the device and stopped using it. Self-service guide devices became a mere decoration, and the money spent by the purchasers was wasted.   Problem 2: Poor battery life, management troublesome, high operating costs   The battery life of self-service guide devices directly determines whether they can be used effectively. Currently, many products on the market can only last for 4-6 hours after a single charge. The equipment will definitely lose power halfway, and staff will have to frequently take it to charge. What's more troublesome is that some products do not come with batch charging and storage equipment. When dozens or hundreds of devices are stacked together for charging, it occupies space, is messy, and is prone to being lost or damaged.   Some products' transmitters also have batteries that run out after a short time, and frequent replacements of batteries are required. Over the long term, the cost of batteries, equipment maintenance, and repair expenses add up to a considerable amount. For units that need to make bulk purchases, such as scenic spots and exhibition halls, the operating costs are too high, and the cost-effectiveness is reduced. Many purchasers have joked that "it's affordable, but not usable".   Problem 3: Complex operation, uncomfortable to wear, not everyone can use it   The users of self-service guide devices are very diverse, including the elderly, children, and foreign tourists. The operation must be simple. However, some products are designed very complicatedly. Manual switching of languages, manual triggering of broadcasting, and even the need to connect to a mobile phone APP to use are required. Even for the elderly, let alone some young people, it takes a long time to figure it out, let alone allowing the elderly and children to operate independently.   In addition, the appearance design of many products is unreasonable. The device body is too heavy, and after wearing it on the ears for a short time, it feels heavy and uncomfortable. The tourist experience is particularly poor. Some products do not support multi-language switching. For some foreign-related exhibition halls and popular scenic spots, where there are many foreign tourists, without multi-language explanations, these tourists cannot use the self-service guide device, and its function cannot be fully exerted.   Problem 4: Poor sound quality, no noise reduction, it's impossible to hear clearly in noisy environments   In the end, the core of self-service guide devices is "making tourists hear clearly". However, in places with many tourists and noisy environments, many products fail. The outdoor traffic and human sounds, as well as the indoor noise, can all mask the audio of the explanations. Tourists have to turn up the volume to the maximum and even attach the device to their ears to barely hear the explanations clearly. The experience is extremely poor.   Some products use traditional sound pickup technology, resulting in unclear explanations and prone to distortion. Especially when introducing the details and historical background of the exhibits, the key information cannot be transmitted, which is like buying something in vain and failing to achieve the "replacing human explanations" effect. Yingmi has accumulated 18 years of experience and used the i7 to break through. It has completely avoided the pitfalls of self-service explanations.   Facing these common pain points in the industry, Yingmi, relying on 18 years of industry accumulation, its own core patent technology, and the full-chain capabilities from research and development to after-sales service, launched the i7 ear-mounted fully automatic sensing guided tour machine. It has targetedly solved the four core problems of positioning, battery life, operation, and sound quality. It is both practical and convenient, with high cost-effectiveness. Many scenic spots and museums are now using it, making it the preferred choice for procurement.   Solution Point 1: RFID precise positioning + anti-interference, no interference, no false triggering   To address the issues of inaccurate positioning and signal interference, Yingmi i7 specifically adopted the RFID-2.4G non-interfering star-shaped distribution design. The light chip selection alone was tested for two years. They chose high-quality chips with strong anti-interference and low power consumption, enabling precise signal switching within about 1 meter. It truly achieves "sound on when you arrive, sound off when you leave", being extremely precise.   Whether in a museum with dense exhibits or an outdoor scenic area with complex terrain, it can accurately identify the visitor's location, only broadcasting the content of the corresponding explanation points, without interference or false triggering. Moreover, it supports 9,999 signal numbers. Even in large exhibition halls and large scenic areas with many explanation points, it can be precisely matched one by one, achieving full coverage of all points. This completely solves the problem of inaccurate positioning.   Solution Point 2: Long battery life + intelligent management, saves manpower and reduces costs   Yingmi i7 has thoughtfully addressed battery life and management issues. It has perfectly solved the problems of short battery life and troublesome management. Its receiver uses a 280mAh lithium battery, which can be used continuously for over 7 hours after a full charge and has an even longer standby time of over 11 hours. The operating time of scenic spots and museums for a day is sufficient. There is no need to take it to charge halfway, saving staff a lot of trouble. The battery of the transmitter is more durable, capable of lasting for 15 months with a single charge, eliminating the need for frequent battery replacements. In the long run, it can save a lot of battery consumption costs. Solution Point 3: Lightweight design + simple operation, suitable for the elderly and children   Yingmi i7's main selling point is "simple and easy to use, comfortable to wear". It has completely lowered the usage threshold. Whether it's the elderly, children, or foreign tourists, they can easily get started. It is an ear-mounted integrated machine, and it is also a relatively lightweight ear-mounted self-service guided tour device in China. The receiver weighs only 17 grams and is only 70×24×12mm in size. It is small and light, and wearing it on the ear does not cause any pressure. Even wearing it for a whole day, it will not feel tired.   The operation is even simpler. There are no complex settings. When tourists receive the device, put on the headphones, turn on the switch, and approach the explanation point, the device will automatically sense and play. There is no need to trigger manually or connect to the mobile app. It also supports multilingual switching. The standard configuration includes 8 languages, and if needed, more languages can be customized. During the switching process, there are language prompts, and it can automatically save the previously selected language for the next startup. Foreign tourists will also find it very convenient to use. Additionally, it has low battery alarm, return reminder, and theft alarm functions, which are both convenient and safe.   Solution Point 4: Professional noise reduction + high-definition sound quality, even in noisy environments, it can be heard clearly.   To address the issues of poor sound quality and insufficient noise reduction, Yingmi i7 employs an embedded digital noise reduction technology based on SOC. This technology can effectively filter out noises from the environment, whether it's the traffic sounds, human voices, or indoor noises. All of these can be suppressed, making the explanation sound exceptionally clear and pure. Moreover, it supports various audio formats such as MP3, wma, and amr. It also uses AI lossless original sound fidelity processing, making the explanation sound as natural as a real person speaking. The details and historical background of the exhibits can be clearly conveyed to the visitors.   FAQ   Q1: Is Yingmii7 suitable for museums with dense exhibits? A1: Definitely! Yingmii7 adopts an RFID-2.4G non-interfering star-shaped distribution design specifically to solve the signal interference problem in museums with dense exhibits and limited space. It can precisely switch signals within about 1 meter, and adjacent explanation points will not cause interference or trigger mistakenly.   Q2: Can Yingmii7 last throughout the 8-10-hour business hours of an attraction or museum? A2: Absolutely no problem! The receiver can be charged fully once and can be used continuously for over 7 hours. The standby time exceeds 11 hours. The 8-10-hour business hours of an attraction or museum are definitely sufficient.   Q3: Is Yingmii7 complicated to operate? Can the elderly and children use it independently? A3: It's not complicated at all. The elderly and children can use it independently. It is fully automatic sensing. When tourists receive the device, put on the headphones, turn on the switch, and walk to the explanation point, it will automatically play without manual operation or the need to connect to the mobile phone APP.   Q4: Does Yingmii7 support multilingual customization? How many languages can it support at most? A4: It supports customization! It comes with 8 languages as standard. If there is a need, whether for minor languages or specific languages, it can be customized according to your requirements, fully meeting the needs of foreign visitors in international exhibition halls and popular tourist attractions.   Q5: How is the after-sales service of Yingmii7? A5: The after-sales service is particularly reliable. You don't need to worry about anything throughout the process. Yingmi has been in this business for 18 years and has a complete after-sales system, implementing 9G full life cycle service.

Whether the noise reduction effect is reliable or not has nothing to do with how loud the advertisement is. The key lies in how many years the brand has been in business, how solid the technology is, and whether it can adapt to the actual usage scenarios. Especially in noisy places like scenic spots, factories, and large-scale conferences, a poorly noise-reduced narrator device not only makes the audience unable to hear the content clearly but also wastes money and may even lower the reception level, resulting in a loss rather than a gain.   Among many brands, there is a well-established manufacturer that has been producing narrator devices for 18 years. Its noise reduction technology is exceptionally solid. Its products not only passed the dual inspections of EU CE, RoHS, and domestic CMA, CNAS, but also served thousands of customers and were sold in dozens of countries. One of its products, the Y3 wireless narrator device with a focus on noise reduction, has always had a very good reputation.   When choosing a wireless narrator device, if the noise reduction effect is poor, it doesn't matter how cheap it is.   When many customers purchase, they often tend to seek cheapness, thinking that as long as it can transmit sound, it's fine. But when they actually use it, they soon realize that a device with poor noise reduction cannot be used at all.   Take scenic spot reception as an example. There are many tourists and a lot of noise everywhere. If the narrator device doesn't have noise reduction, the audience will hear only the noise of the crowd and the honking of cars, and can't hear what the narrator is saying clearly. The originally good guided experience is ruined by the noise; for example, in a factory visit, the machines are roaring, and the noise is particularly loud. Ordinary narrator devices cannot filter out such high-frequency noise, and the narrator's voice is directly covered over, making it impossible for the visitors to understand the product process and the situation of the enterprise. And in government receptions and large-scale conferences, the clarity of the narration is more demanding. Even a little noise can affect the reception effect. If the noise reduction is not adequate, it will actually make things worse. How good the noise reduction effect is can be judged by these 3 points:   1. High-frequency band design: Reducing interference from the source   The frequency band of the wireless narrator device directly affects the noise reduction and anti-interference effect. Many ordinary narrator devices use low-frequency bands, which are particularly prone to interference from electronic devices such as mobile phones and radio stations, and will also be covered over by low-frequency noise in the environment. The noise reduction effect naturally won't be good.   Yingmi Y3 is different. It uses the 2.4GHz high-frequency band. The advantage of this frequency band is obvious. It can avoid interference from commonly used electronic devices and reduce the interference from low-frequency noise in the environment, thus improving the noise reduction effect fundamentally. Whether in a noisy scenic spot or a factory with roaring machines, it can transmit sound stably, and the noise is reduced, so the audience can clearly hear every word of the narration.   2.Digital noise reduction technology: Precisely filtering noise, preserving the original sound   If the frequency band is the foundation of noise reduction, then the noise reduction technology is the core. Yingmi has been producing narrator devices for 18 years and has a solid technological accumulation. It embedded its developed SOC embedded digital noise reduction technology into the Y3 product. The advantage of this technology lies in its ability to precisely distinguish between the narrator's voice and environmental noise, and when filtering noise, it can also maximize the preservation of the original sound, without causing problems such as "too much noise reduction, the narrator's voice becomes distorted and unrecognizable".   We have actually tested it. Even when the environmental noise reaches 60 decibels, wearing the YingmiY3 narrator device, you can clearly hear the narrator's voice, and the surrounding noise and noise will be filtered out, just like listening to someone explain in a quiet room. This precise noise reduction ability is exactly what makes YingmiY3 stronger than ordinary narrator devices.   3.Strong anti-interference ability: Not affecting each other when used by multiple devices   Often, narrator devices need to be used together, such as multiple teams visiting or different batches of explanations in large-scale conferences. In this case, anti-interference ability is crucial. If the anti-interference is not good, when multiple devices work together, there will be interference sounds and interruptions. The listeners will be confused, and the narrator will be annoyed, resulting in a very bad experience.   Yingmi Y3 supports "one-to-many" usage. One transmitter can be paired with countless receivers, and it has strong anti-interference capabilities. Even when multiple devices are used simultaneously, there will be no interference or interruption of sound. Each group of listeners can clearly hear the corresponding explanation. In addition, Y3 has 4 adjustable channels, which can be flexibly switched according to the usage scenario, further enhancing the anti-interference effect. It is also completely fine for multiple teams to use simultaneously. Y3 is fully compatible for all scenarios: noise reduction online, balancing convenience and practicality.   A good wireless device not only needs good noise reduction, but also needs to be convenient to use and comfortable to wear. After all, whether it's the narrator or the audience, no one wants to use an equipment with complex operation and a cumbersome design. Yingmi Y3 has considered this aspect very thoroughly and truly achieved "good noise reduction and easy use".   First, the wearing experience. The receiver of Y3 is very small and is of non-in-the-ear design. This non-in-the-ear design can directly reduce environmental noise and enter the ear. Combined with its digital noise reduction technology, it provides double guarantees, making it easier to hear clearly.   The operation is also very simple. Pressing the SET button can turn it on. After turning on, it will automatically search and connect the signal. No complex settings are required. Whether it's the elderly or the young, they can pick it up and fiddle with it for a couple of times and start using it. The transmitter has a full-function LCD display. The channel, volume, battery power, and signal strength can all be clearly seen. The narrator can adjust the parameters at any time and doesn't have to worry about signal interruption or insufficient volume.   There is no need to worry about battery life either. Y3 is equipped with high-performance, safe and environmentally friendly polymer lithium batteries. Once fully charged, it can be used continuously for 8-10 hours. The receiver can last for more than 8 hours, and the transmitter is more durable, lasting up to 15 hours. It is completely sufficient for the daily usage needs. It is also equipped with a dedicated charging box, which can charge multiple devices at the same time. Not only is the charging fast, but it can also be properly stored and transported. When storing or placing it, there is no need to worry about the equipment being damaged.   In addition, the transmission range of Y3 can reach over 200 meters. Even in large scenic areas or spacious factory workshops, it can transmit sound stably without interruption or noise. Moreover, the volume can be freely adjusted. Listeners can adjust the appropriate volume according to their own needs, making it more comfortable to listen.   Yingmi has been making narrator devices for 18 years, and its quality and after-sales service are very reliable. Each device must undergo 5 strict inspections in the 7S quality control system. Those that fail will not enter the market. Moreover, it has a professional after-sales team that can provide free technical support and professional installation services. The purchasing party doesn't need to worry about any subsequent problems.   FAQ   Q1: What are the main factors determining the noise reduction effect of the wireless explainer? A1: The core factors are three: frequency band, noise reduction technology, and anti-interference capability.   Q2: Is Y3 suitable for use in noisy environments? A2: Yes, it is. 2.4GHz high-frequency band + digital noise reduction, even in noisy conditions, you can hear clearly.   Q3: Will Y3 cause interference when used by multiple devices simultaneously? A3: No, it has strong anti-interference ability and supports simultaneous use by multiple devices, without affecting each other.   Q4: Is Y3 comfortable to wear? Does its battery life meet the needs? A4: It is lightweight and has a non-ear-insert design, making it comfortable to wear; the battery life is 8-15 hours, sufficient for all-day use.   Q5: Will the noise reduction of Y3 cause distortion in the explanation? A5: No, it precisely filters out noise and retains the original sound, ensuring clear and distortion-free explanations.

There are numerous brands of wireless tour guide devices available on the market, and their quality varies greatly. Many products boast exaggerated parameters, but when used, they often encounter problems such as crosstalk and disconnection. In fact, most people don't realize that the stability of a wireless tour guide device is not solely dependent on a single parameter. Instead, it is the result of a collective effort in areas such as technological research and development, production control, and battery life.   The stability of a wireless tour guide device is primarily evaluated based on these four key dimensions   When determining whether a wireless tour guide device is stable or not, it's not necessary to focus solely on the fancy additional features. Instead, by accurately grasping the following four core dimensions, you can quickly filter out suitable products. This is also the recognized and tested stability evaluation standard in our industry, helping many customers avoid pitfalls.   Anti-interference capability: Reject crosstalk and disconnection, remain stable in complex environments   The most troublesome stability issue with wireless tour guide devices is crosstalk and signal interruption. In crowded and electronic equipment-rich environments, such as large exhibition halls, popular tourist attractions, and corporate annual meetings, there are numerous mobile phone signals and radio signals, which can easily interfere with the tour guide device, causing the content to become chaotic and even suddenly losing connection. Therefore, a high-quality wireless tour guide device must have a strong anti-interference capability to operate stably in these complex environments.   The core of anti-interference capability lies in signal modulation technology. Currently, the mature technologies in the industry can effectively avoid various external interferences and also reduce the channel bandwidth. Even if multiple teams are explaining simultaneously, there will be no mutual interference or crosstalk. In addition, digital filtering and noise reduction technologies can also help, filtering out environmental noise and ensuring the purity of signal transmission, preventing signal interruption due to noise, and allowing for more coherent explanations. Signal transmission: Long-distance without attenuation, no lag when passing through walls   Whether it's exhibition hall explanations, factory visits, or large exhibition hall receptions, the explanation scenarios often require long-distance transmission and may encounter obstacles such as walls and doors. The stability of signal transmission directly affects the user experience. If the signal transmission capability of a wireless tour guide device is insufficient, when the distance is slightly increased or there is a wall obstruction, there will be audio quality lag, signal loss, and intermittent explanations, resulting in a particularly poor experience.   High-quality tour guide devices will use advanced wireless amplification technology to optimize the signal transmission path, achieving lossless long-distance audio transmission and enhancing the ability to pass through walls. Even in complex scenarios such as large factories and multi-story exhibition halls, the explanations can be clear and coherent without delays or lags, and there is no need to repeatedly adjust the equipment.   Battery life stability: Long-lasting battery life without interruption, worry-free all-day use   Most wireless tour guide devices are used continuously throughout the day, especially in exhibition halls and museums, where there are a large number of visitors every day, and the equipment needs to run continuously for several hours. Battery life stability is truly crucial. If the battery life is insufficient, frequent charging is required, which not only slows down the reception efficiency but also may cause the explanation to suddenly stop, leaving a bad impression on the audience. This can easily lead to complaints later.   Battery life stability is not only determined by battery capacity but also by power management technology. Efficient power management technology can reasonably allocate power, reduce power consumption, extend battery life, and also come with a low battery alert function, allowing staff to promptly know the battery status and avoid using the equipment due to sudden power outages. Additionally, convenient charging methods are also important, such as being able to charge multiple devices simultaneously and supporting fast charging, which can significantly improve the reception efficiency.   Quality control stability: Strict details, no malfunctions during long-term use I have seen many cheap products with seemingly acceptable parameters, but after using them for a while, problems such as malfunctioning buttons, deteriorating sound quality, and malfunctions of the body occurred. In the end, it was due to poor quality control and cutting corners. High-quality brands always establish strict quality control systems, from component procurement, production assembly, to finished product inspection, each step is closely monitored to ensure that each device remains stable for a long time and maintains stable performance.   Having been deeply involved in the industry for 18 years, Yingmi has built a solid foundation of stability through technology and quality control.   In the interpreter equipment industry, the longer a brand has been in business, the deeper its accumulation, and the more stable its products will be. Yingmi, a national-level high-tech enterprise and big data enterprise, has established a complete service system from research and development, production, to sales and after-sales services. With its profound technical accumulation and strict quality control standards, the wireless interpreters it produces have outstanding stability. Among them, the E8 wireless interpreter has become the benchmark product in terms of stability in the industry.   Yingmi has 4 automated SMT production lines, equipped with fully automatic printing machines and AOI optical inspection equipment, achieving independent production of PCBA, filling the gap from research and development to production. They firmly grasp the quality of each product from the source. At the same time, it has established a 7S quality control system. Each device must undergo 5 strict inspections, ensuring that the signal transmission, anti-interference, battery life, and sound quality all meet the standards before it can be manufactured, ensuring a 100% qualification rate and no malfunctions over a long period of use.   In terms of technological research and development, Yingmi holds several core patent technologies. The 4GFSK signal modulation technology can effectively block external interference such as mobile phones and radio stations, ensuring channel security; the SOC embedded integrated digital filtering and noise reduction technology can minimize environmental noise and achieve lossless audio transmission; the PMU secure intelligent lithium battery power management technology can reasonably allocate power and significantly improve the stability of battery life. These core technologies are all applied to the E8 wireless interpreter, comprehensively enhancing the stability of the product. Scene testing: The E8 wireless interpreter has outstanding stability for all scenarios   For different stability requirements in different scenarios, Yingmi's E8 wireless interpreter has undergone multi-scenario real-world tests. Whether it is in crowded exhibition halls, long-distance factory visits, or long-term scenic area receptions, it can maintain excellent stability. Many customers will prefer it when purchasing.   The E8 is an integrated design, weighing only 16 grams, fashionable and lightweight. The body is made of high-quality materials, resistant to wear and tear, and not prone to damage over a long period of use. In terms of anti-interference, relying on the 4GFSK signal modulation technology and digital secondary frequency anti-interference technology, even when multiple teams are visiting and explaining simultaneously, they can operate independently without interference or interruption, and the signal transmission is particularly stable; in terms of signal transmission, the effective range can reach 150-200 meters, and the wall-penetrating effect is also good. It can ensure clear and coherent explanations in large exhibition halls, factories, and scenic areas.   In terms of battery life stability, the E8 is equipped with high-performance polymer lithium batteries, with the transmitter able to work continuously for 8-15 hours and the receiver able to work for more than 8 hours continuously.

When visiting scenic spots or museums, even though the sights and exhibits are worth a close look, one can only enjoy the spectacle without understanding the historical and cultural background. Joining a tour group is fine, but the tour guide's voice is drowned out by the noise of the crowd, and the passengers in the back rows are left to listen to nothing. Free travel is even more awkward; wanting to learn some details, one either can't find a professional guide or has to hold a phone to look up information. While being fully engaged, the trip is suddenly interrupted, and the enthusiasm vanishes.   Now, a handy self-guided audio device has become the key to enhancing the travel experience. Among many brands, Yingmi, which has been deeply involved in the audio guide industry for 18 years, has launched the M7 chest-mounted fully automatic sensor guided tour device. This device has achieved the ultimate combination of "lightness and portability" and "professional and practicality", perfectly solving the pain points of travel guidance and allowing every trip to truly understand the scenery and gain a lot.   When choosing a travel audio guide, two points are crucial: portability and professionalism. Without either one, it won't be good enough.   Travel is different from other scenarios. Tourists are carrying luggage and holding cameras, so they are already quite tired. In fact, the requirements for the audio guide are quite simple: first, it should be easy to carry and not cumbersome; second, it should be easy to use and allow clear listening. However, many audio guide devices often get stuck at these two points, becoming a "stumbling block" for the travel experience.   What's more frustrating is that some devices' sensing is particularly inaccurate. When you approach the guidance point, it doesn't respond for a long time; when it finally starts playing, you are already far away, and it keeps looping the same content. Sometimes, for adjacent two scenic spots that are close, the signals will interfere with each other, and you hear this and that in your ears, making it even worse than not listening at all. It's better not to listen at all.   Not only do tourists find it annoying, but the operators of the scenic spots also have difficulties. Charging them in batches is troublesome; stacking dozens or hundreds of devices together takes up space and is difficult to manage; storage is also troublesome, as the devices are prone to being lost or damaged, and the cost of maintenance and replacement is high. Therefore, a self-guided audio device that can truly enhance the travel experience not only needs to make tourists feel comfortable to use but also needs to make the operators manage it easily. Portability and professionalism are both indispensable, and Yingmi M7 just meets both of these points. Yingmi M7: 3 Core Advantages, Elevating Travel Guidance Experience to the Max   As Yingmi's sincere creation after 18 years of deep involvement, the M7 chest-mounted fully automatic sensor guided tour device has no fancy functions; it's all solid and practical designs, from the appearance to the functions, every aspect is tailored to the travel scenario, completely solving the pain points of traditional audio guides.   Extremely lightweight, hanging it on your chest feels just as if it's not there at all.   For tourists, the portability of the audio guide directly determines the willingness to use it. Yingmi M7 is particularly considerate; it adopts a chest-mounted design, with the entire body weighing only 50g and measuring 82×59×12.5mm. It's small and thin, and wearing it on your chest feels almost nothing, even if you spend the whole day visiting the scenic spots, you won't feel tired, and it won't interfere with enjoying the scenery and taking photos.   The shell is in pure white lacquer finish, looking simple and clean, and it doesn't clash with any clothes.

More importantly, its operation is very simple; there are no complex settings, and tourists can simply take the device, put on the headphones, turn on the switch, and start using it. It's fully automatic sensing, no need to manually trigger or connect to a mobile phone app. The elderly and children can learn to use it in just one glance, truly achieving an "unobstructed" experience.   Long battery life + convenient management, making tourists' trips in the scenic spots worry-free.   The travel itinerary is already tight, and no one wants to stop to charge the audio guide halfway. For the scenic spots, managing dozens or hundreds of devices in batches is also a big project. Yingmi M7 has thought very carefully in this regard, completely solving the problems of battery life and management. Its receiver is equipped with an 800mAh large-capacity lithium battery. Once fully charged, it can operate continuously for more than 16 hours. Even for long-distance tours with early morning starts and late-night ends, there is no need to worry about power outages in the middle. Tourists can enjoy the tour without constantly worrying about charging. The battery of the transmitter is more durable, capable of being used for 15 months. There is no need to frequently replace the battery, which can also save a lot of operating costs for the scenic area.   To meet the demand for batch management in scenic areas, M7 is also equipped with a dedicated charging box and storage box. The charging box comes in two sizes, capable of charging 36 or 48 devices simultaneously. It uses a 220V input and a 5V-20A output, which can charge quickly and protect the battery, extending the lifespan of the equipment. Some models even have an ultraviolet disinfection function, making it more hygienic for tourists to use. The storage box is made of all-aluminum material, with silicone grooves and a top sponge. When the equipment is placed inside, it fits perfectly, and it will not be damaged by vibration during transportation or storage. One box can hold 50 devices and accessories, making storage and carrying very convenient. It also saves the efforts of the scenic area staff in management.   The sensing is precise without interference, and the explanation content is clear and refreshing.   The self-service explainer, the core is "precise explanation". If the sensing is inaccurate and there is interference, it is better not to use it at all. Yingmi M7 is particularly solid in this aspect, completely getting rid of the pain points of traditional equipment.   It adopts a RFID-2.4G star distribution system design, and is also equipped with digital coding area positioning identification technology and spread spectrum communication technology. It can precisely control the transmission and reception distance of the signal, effectively solving the problem of signal interference between adjacent scenic spots. The sensing range can be flexibly adjusted within 0.5-40m. Whether it is an open area in the scenic area or a multi-exhibition environment in a museum, it can accurately identify the position of the tourists, and automatically play the content when they reach the corresponding explanation point. Once they leave, the playback stops without any interference, mis-triggering, or repeated broadcasting.   Moreover, it supports 9999 signal numbers and 9999 segments of explanation content storage. Even for large scenic areas or exhibition halls with many explanation points, it can achieve full-point coverage, from the historical background of the scenic spots to the detailed stories of the exhibits, and can clearly convey them to tourists, allowing them to understand and comprehend clearly without the need for a "skimming" approach.   Multi-language coverage, suitable for both foreign and domestic tourists.   Now that cross-border tourism is gradually recovering, and many popular scenic spots and museums have foreign reception requirements, multi-language explanations have become a necessity. Yingmi M7 comes with 8 languages as standard. Whether it is foreign tourists or domestic tourists who need dialect explanations, they can find a language version that suits them.   What's more, different tourists can choose different languages at the same scenic spot without interfering with each other, perfectly adapting to the diverse reception needs of scenic areas and museums. Moreover, the device will automatically save the last selected language and does not need to be reconfigured next time it is turned on. It is very convenient to use and truly breaks the language barrier, allowing every tourist to deeply experience the cultural charm behind the scenery.   FAQ   Q1: Is the Yingmi M7 comfortable to wear?
