Quality Tour Guide Audio System & Wireless Tour Guide System Factory

When international tour guides lead tours, they often face difficulties choosing wireless audio devices - multiple teams sharing the same audio equipment causes interference, making it hard for tourists to hear the explanations clearly; the device's battery life doesn't last the entire day, and power outages are embarrassing; tourists complain about ear pain after wearing it for a long time, and there are continuous complaints; even when they receive the device, they find that it doesn't have international certification, making customs clearance a problem. In fact, for tour guides, a good tour guide audio device doesn't need to be overly fancy; the core features are "resistant to interference, long battery life, comfortable to wear, international-compatible, and easy to maintain after-sales service".   Ⅰ.Choosing an audio device for tour guiding   Tour guiding scenarios are very special - crowded and noisy scenic spots, fixed team routes, a wide age range of tourists, and cross-national use. Ordinary audio devices are prone to show shortcomings in these aspects. The pain points reported by international tour guides are mainly concentrated in these 4 points. Brands that fail to solve these problems will not be selected.   1. Poor interference resistance: Multiple teams sharing the same audio equipment causes interference and chaos in the explanation rhythm   Hotspots and museums have dozens of teams every day. If the audio device doesn't have good interference resistance, team A tourists can hear team B's explanations. The tour guide is explaining local history, and the noise mixes in other tour guides' explanations of the scenic spot legends. The tourists' experience is poor, and the tour guide has to repeat repeatedly, wasting effort. This is the most troublesome problem for tour guides and the primary criterion for judging the quality of the audio device.   2.Poor battery life: Midway through the tour, frequent charging is required   International tour guides lead tours for 6-8 hours or more, and sometimes even 10-12 hours. If the audio device's battery life is only 4-5 hours, they have to find a place to charge, which not only delays the itinerary but also has to carry a bunch of chargers, adding extra burdens. Especially when conducting tours outdoors, finding power sources is difficult, and power outages are a fatal problem.   3.Uncomfortable wearing: Tourists complaining after wearing for a long time, affecting the tour guiding experience   Tourists follow the tour guide for a whole day. If the audio device is heavy and has an in-ear design, after wearing it for a long time, the ears will hurt and feel stuffy, easily causing resistance and even removing it halfway. Especially for elderly tourists and children, they have higher requirements for wearing comfort.   4.Poor international compatibility: Difficulty in customs clearance, voltage mismatch, and inability to use upon arrival   International tour guides are most worried about "the device not working when it arrives": without international certifications such as EU CE or RoHS, it may be detained during customs clearance; the charging voltage is incompatible, and 220V in Europe and 110V in America cannot be used universally; the instructions are all in Chinese, making it impossible to explain the operation to tourists, and these problems can completely disrupt the tour guiding rhythm.   5.Why Yingmi is the preferred choice for international tour guides? Core advantages hit the demand   Yingmi has become the fixed choice for tour guides in many international tourism routes, such as Suzhou Taihu Scenic Area, Jiangxi Longhu Mountain, and Xiangkun Temple in Vientiane, Laos. It has also been exported to multiple regions in Europe, America, and Asia. The core reason is that it has completely solved the pain points of tour guiding, hitting the needs of international tour guides in every aspect.   Ⅱ. Advanced interference resistance technology: Even in the same scenic spot with 100 teams leading tours, there will be no interference   Yingmi has optimized interference resistance technology for tour guiding scenarios. The 008A and K8 models commonly used by tour guides all adopt 4GFSK signal modulation technology, with a 200k ultra-small channel bandwidth, which can open 100 independent channels. In simple terms, even if 100 teams are leading tours in the same scenic spot at the same time, there will be no interference.   More importantly, the signal stability is the key. The communication distance of 008A can reach up to 280 meters, with excellent wall-penetrating effect. Even if the tour guide is leading tours in the small alleys of the scenic spot or tourists temporarily leave to take photos, they can clearly hear the explanation. K8 also supports automatic frequency matching, and tourists can match the tour guide's transmitter as soon as they turn on the receiver, without the need for manual adjustment, saving a lot of trouble.   1.Long-lasting battery life + durability: No pressure for all-day tours Yingmi fully understands the endurance anxiety of tour guides.   It adopts the PMU safe and intelligent lithium battery power management technology. Most of its receivers can have a battery life of 7-8 hours, and the transmitter can last for over 15 hours. Even when taking a full-day tour, there is no need for charging in the middle. Combined with a dedicated charging box, batch charging is fast and safe. After the tour guide finishes the tour, they can simply put the equipment into the charging box, and it can be used the next day. The durability also stands the test of time. Yingmi has its own SMT surface mount factory (Hefei Suichang Electronics), with a fully controllable process from research and development to production. Each device must undergo 5 strict tests, including high temperature, low temperature, vibration, etc. Tour guides are bound to bump into things during the tour, but even if the equipment accidentally falls on the ground, it is unlikely to break, making it particularly suitable for frequent tours.   2.Comfort Design: Tourists won't complain after wearing for a whole day   Yingmi has deeply studied the wearing requirements of tour guides. Most of its devices adopt Ergo ergonomic design. For example, the popular R8 ear-pendant guide device is non-in-the-ear design, weighing only 22g. Even after wearing for a long time, tourists won't feel pain in their ears, and it also solves the hygiene problem of in-the-ear devices - after all, tour guides need to serve different tourists, and hygiene is extremely important.   The E8 integrated guide device is even lighter, weighing only 16g. The integrated design is fashionable and compact, making it convenient for tourists to carry, even when taking a family tour, children won't feel burdened when wearing it.   III. How to Choose for Different Tour Scenarios? Yingmi Models Match Precisely   The scenarios and requirements for tour guides are different - for long-distance bus tours and small group tours, the selected equipment will definitely be different. Based on the common scenarios of international tour guides, these models can precisely match:   1. Long-distance bus tours and outdoor scenic area tours: Choose the 008A wireless guide device   This is the "mainstay" for outdoor tours. The communication range can reach up to 280 meters, even if the tour guide is giving a speech on the bus, tourists can still hear clearly when they move briefly on the ground; the sound transmission effect is first-class, and it won't lose sound in scenarios such as visiting ancient cities and temples with multiple buildings; its durability is particularly good, with full dust-proof and anti-drop performance, it can handle outdoor wind and sand, and light rain; the package is flexible, one transmitter can connect multiple receivers, suitable for different-sized teams, and many tour guides of multinational outdoor tours have been using this model for years.   2.Frequent tours, emphasizing comfort: Choose the R8 ear-pendant guide device   If the tour guide takes tours every day, comfort during wearing is the core requirement. Choosing R8 is definitely the right choice. The non-in-the-ear ear-pendant design solves the problem of pain from long-term wearing and hygiene issues. Tourists' feedback is "wearing for a whole day is the same as not wearing at all"; the sound quality is clear, equipped with SOC embedded integrated digital noise reduction technology, which can precisely filter out the noisy sounds in the scenic area, making the explanation sound clearer.   Its operation is also simple. The receiver automatically synchronizes when turned on, and the tour guide doesn't need to spend time teaching tourists to operate, saving a lot of energy. 3.Multiple teams parallel, large group reception: Choose the K8 team guide system   If the tour guide is leading a large group of dozens of people or in a popular scenic area with other teams, the K8 is the best choice. It can open multiple independent channels, even if multiple teams are leading tours simultaneously, there will be no interference; it supports one-to-many explanations, one transmitter can connect countless receivers, and it can automatically synchronize, making it easy to handle large group receptions.   Many tour guides in Suzhou Taihu Scenic Area use this device for tours every day, receiving multiple large groups, and there have never been problems of interference or sound loss, with an excellent reputation.   IV. Finally, to be honest: Tour guides choose guide devices, reliability is more important than anything else   For international tour guides, the tour guide device is not a "small accessory", but a core tool to ensure tour quality. Choosing the right brand can save a lot of trouble - no need to worry about interference, no need to be anxious about battery life, no need to worry about customs clearance, just focus on giving explanations.   Yingmi has accumulated years of industry experience, covering everything from anti-interference technology to comfortable design, from international certifications to cross-border after-sales services. Every step is tailored to the needs of tour guides leading groups. Whether it's leading outdoor tours, boutique tours, large groups, or multiple groups operating simultaneously, there are corresponding solutions. There is no need to worry about "which one is better". The practical experience of many international tour guides has proved that choosing Yingmi will make the tour planning much more convenient.   Product Model Target Scenarios Core Features Key Advantages Yingmi 008A Wireless Guide Device Long-distance bus tours, outdoor scenic areas (ancient cities, temples), harsh environments 280m max communication distance; strong wall-penetrating ability   Dust-proof, drop-resistant, slight water-proof (handles wind, sand, light rain)   One transmitter connects multiple receivers (flexible for different team sizes) Ideal for outdoor tours with scattered tourists   Durable for frequent use in harsh conditions Yingmi R8 Ear-Pendant Guide Device Daily tours, boutique small-group tours, comfort-focused scenarios 22g lightweight, non-in-ear design (hygienic, no ear pain)   SOC embedded integrated digital noise reduction (clear sound in noisy scenic spots)   Automatic synchronization (no user training needed) Perfect for tour guides leading daily tours   High tourist satisfaction with wearing comfort Yingmi K8 Team Guide System Large-group reception (dozens of people), popular scenic spots with multiple parallel teams 100 independent channels (no interference with multiple teams)   One-to-many explanation (supports countless receivers)   Automatic frequency matching (easy for large groups) Trusted by Suzhou Taihu Scenic Area for daily large-group reception   Solves interference in crowded scenic spots Yingmi E8 Integrated Guide Device Family tours, small groups, fashion-focused users 16g ultra-lightweight, integrated compact design   Fashionable appearance (suitable for all ages)   Clear sound quality with noise reduction technology Convenient for family travel (children won’t feel burdened)   Easy to carry and operate   FAQ   Q1: Can the Yingmi interpreter be exported to our country?

When foreign tourists visit Chinese scenic spots, the most troublesome issues are language barriers and unclear explanations - following the tour guide and getting stuck in a crowd, with noise overwhelming the explanations; wanting to freely explore but not being able to understand the stories behind the attractions. For scenic spot operators, choosing a reliable wireless tour guide device is the key to solving these problems. However, many people are confused: should they choose a trader or an origin factory? The answer is simple: The wireless tour guide devices for scenic spots need to be robust, stable, adaptable to different scenarios, and also need to meet the needs of global tourists. Only an origin factory can achieve all these.   In the field of wireless tour guide devices for scenic spots, the Yingmi brand under HEFEI HUMANTEK. CO., LTD. is a genuine origin factory. Since its establishment in 2007, Yingmi has focused solely on making tour guide devices and has deeply cultivated the industry for many years. It has its own SMT assembly factory and 4 automated production lines. It controls the entire chain from research and development, production to sales and after-sales services. The products have passed EU CE, RoHS certifications, and are exported to dozens of countries in Europe, America, and Asia. It has served over 4,000 scenic spots and has become the preferred choice for many scenic spots worldwide.   Why are origin factories more reliable when choosing wireless tour guide devices for scenic spots?   For scenic spots, especially those that receive international tourists, wireless tour guide devices are not "one-time consumer goods" but core equipment for long-term services. Choosing an origin factory essentially means choosing convenience, stability, and long-term guarantee. These points are particularly important for foreign customers.   Advantage 1: Dual guarantees of compliance and production capacity, no worries about stockouts or rejection   Foreign customers are most concerned about two things: one is that the product is not compliant and cannot pass customs; the other is that there is a shortage of products when making large-scale purchases, which delays the operation of the scenic spot. Yingmi, as an origin factory, has already solved these two problems. All scenic spot series tour guide devices have passed EU CE, RoHS certifications, as well as Chinese CMA and CNAS dual standard tests. When exported to countries like France, Germany, and Malaysia, they pass customs smoothly. It has its own 4 automated SMT production lines. Even if the scenic spot orders thousands of devices at a time, they can be delivered on time, and there is no need to worry about stockouts during peak seasons.   Advantage 2: Technology controlled by oneself, adaptable to complex scenic spot scenarios   Scenic spot scenarios are too complex: crowded and noisy, spacious, with indoor exhibition halls and outdoor paths. Ordinary tour guide devices are prone to interference, unclear sound, and signal disconnection problems. Yingmi, as an origin factory, has its own R&D team. Core technologies are all independently developed. For example, the unique SOC embedded integrated digital noise reduction technology can filter out the crowd noise and wind noise, ensuring clear explanations even when there are many people. 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, meeting the safety requirements of scenic spots. Unlike traders, who can only sell ready-made products, they cannot optimize problems specifically when encountering issues.   Advantage 3: Strong after-sales support, and worry-free cross-border services   Tour guide devices are used every day, and there will inevitably be wear and tear. Inadequate after-sales services will directly affect the service of the scenic spot. Yingmi, as an origin factory, has no worries about after-sales: it provides 24-hour multilingual customer service. Even foreign customers can communicate in English, French, or German without problems; it supports cross-border repair, and the faulty equipment can be repaired within 10 working days, and emergency replacements can be provided when needed; products have a 3-month warranty period, and if there are quality issues, they can be replaced directly; within one year, they can be repaired free of charge. Unlike traders' "outsourced after-sales", Yingmi's after-sales service is much more reliable.   Yingmi: A genuine origin factory for scenic spot tour guide devices, with visible hard power   Yingmi has become a choice for many global tourist attractions, not because of the advertising hype, but because every step, from research and development to production and service, is carried out with great diligence, fully meeting the core standards of the original manufacturer.   Integrated R&D and production: From chips to finished products, the entire process is controlled by themselves.   Yingmi invested in the SMT assembly factory in Hefei, Shoucheng Electronics, as early as 2010, achieving independent production of PCBA, filling the gap from research and development to production. In simple terms, from the core chips to the final audio guide products, everything is controlled by themselves, without relying on external contract manufacturers. This can ensure stable product quality and quickly adjust product parameters according to the needs of the tourist attractions. For example, to meet the demand of multiple teams giving explanations simultaneously at the tourist attractions, Yingmi developed digital secondary frequency anti-interference technology with a 200k ultra-small channel bandwidth. Multiple teams can use it without interference. This is the technical advantage of the original manufacturer.   There are enough customer cases: Validation by tourist attractions, with cooperation all over the world.     Whether the strength is good or not, it is decided by the customers. Yingmi has served tourist attractions all over the world, including the 5A-level scenic spots in Suzhou Taihu Lake, Jiangxi Longhu Mountain Scenic Area, Xiamen Gulangyu Scenic Area, and Jiangsu Tianmu Lake Scenic Area, which have been using Yingmi's audio guides for a long time. The Laoxian Xiangkun Temple tourist attraction in Laos also specifically hired Yingmi to install self-service audio guiding equipment. Even high-end events such as international museum senior forums and SCO meetings chose Yingmi to provide guiding services. Receiving recognition from so many professional customers is more persuasive than any advertisement.   Selecting the right product for the tourist attraction scenarios makes Yingmi's solution highly adaptable.   The needs of different tourist attractions are different: some have a large number of tour groups, some have a large number of independent travelers, some have indoor exhibition halls, and some are large outdoor tourist attractions. Yingmi, as the original manufacturer, has developed multiple products specifically for different tourist attractions, and can find an adaptable solution for any type of tourist attraction.   Tourist attraction with dense teams: E8/K8 team audio guiding system, no interference for multiple teams   For tourist attractions with a large number of tour groups, such as Suzhou Taihu Lake and Jiangxi Longhu Mountain, Yingmi's E8 or K8 team audio guiding system is tailor-made. The E8 receiver is only 25 grams, with an earpiece design that does not distinguish left and right ears, and is comfortable even after long use by tourists; it adopts U-band high-frequency radio wave technology, with extremely strong anti-interference ability, and the transmission distance can reach 200 meters. Even if tourists are scattered for taking photos, they can still hear the guide's instructions such as "There is a steep slope ahead, pay attention to your footing" and "The assembly time will be extended by 10 minutes".   The K8 team audio guiding system is more suitable for tourist attractions with high quality requirements. It adopts an in-earless earpiece design integrated with the headband, weighing only 22 grams, and is comfortable and hygienic to wear. The biggest advantage is automatic frequency matching, with the receiver starting to match the transmitter as soon as it is powered on, without the need for manual channel adjustment; it also has an LCD display, allowing you to clearly see the battery level, channel, and volume, and the main speaker can pre-store explanations, and you can play them directly when tired, saving a lot of trouble. The professional contact-type charging box is made of metal, safe and without any hidden dangers, and can charge up to dozens of units at once, making it very convenient for tourist attraction management.   Tourist attraction with a large number of independent travelers: i7 earpiece/ M7 neckband automatic sensing audio guide machine   The i7 and M7 two types of self-service audio guiding machines from Yingmi are very suitable for tourist attractions with a large number of independent travelers. The i7 earpiece weighs only 20 grams and is hardly noticeable when hung on the ear, without affecting taking photos or carrying a hiking stick; it adopts advanced RFID automatic sensing technology, and when tourists reach the corresponding scenic spot, they do not need to make any movements, the device will automatically play the explanation, such as when reaching the top of the viewing platform, it will automatically explain the formation history of the mountains, and when reaching the stream side, it will explain the story of the water source.   The M7 neckband audio guiding machine is more suitable for long-term visiting tourist attractions. The 50-gram neckband design is very lightweight and can last for 16 hours of use throughout the day. It also supports automatic sensing. Moreover, it can be adjusted through the APP for speaking speed and language switching. Foreign tourists can listen to the explanations in their native language without having to painstakingly translate the text. The accompanying all-aluminum storage box can hold 30 devices and is also shockproof. This makes transportation and storage in the scenic area much more convenient.   FAQ   Q1: Can Yingmi's audio guide system obtain the EU certification? Is it compliant for use in European scenic areas? A1: Absolutely! All the scenic area series audio guides have passed the EU CE and RoHS certifications, and have also undergone dual inspections in China's CMA and CNAS. Currently, they are exported to European countries such as France, Germany, and the United Kingdom on a regular basis, and there are no issues when passing through customs.   Q2: With a large number of people and noisy environments in scenic areas, will there be interference or unclear sound during the explanation? A2: No! Yingmi adopts SOC embedded integrated digital noise reduction technology and digital secondary frequency anti-interference technology. It can effectively filter environmental noise and other signal interference. Even if multiple teams are explaining simultaneously, there will be no interference, and the sound quality is clear and pure. In an environment of 85 decibels, it can still be heard clearly.   Q3: Can custom-made small-language explanations for scenic areas be provided? Is the switching convenient? A3: Yes, customizations are possible! The default supports 8 mainstream languages, and small-language options such as Arabic and Portuguese can be customized as needed. The switching is very simple. The equipment has international universal icons and can be switched with one click. It also supports language memory, and there is no need to reconfigure when starting up next time.   Q4: For bulk purchases, how long is the delivery cycle? Can it guarantee supply during peak seasons? A4: Yingmi has 4 automated SMT production lines and is self-manufactured in its own factory. Regular orders can be delivered within 7-10 days. Large orders can be discussed in advance, and it can fully guarantee supply during peak seasons without any shortage.   Q5: After foreign scenic areas make purchases, is the after-sales maintenance and technical support convenient? A5: Extremely convenient! We provide 24-hour multilingual customer service, supporting communication in languages such as English, French, and German. The equipment supports cross-border repair. After receiving the faulty equipment, the repair will be completed within 10 working days.

The most frustrating thing when visiting a museum is undoubtedly the situation where you have to squeeze into a crowd with a tour guide, while your ears are filled with noise, making it impossible to understand the story behind the exhibits. When encountering foreign tourists, language barriers prevent you from understanding the exhibits, and you can only stare at the relics blankly. If several groups of visitors gather together, the various audio guides create a chaotic noise, completely ruining your mood to enjoy the exhibition. For museums, purchasing a wireless tour guide device is not difficult, but choosing the right manufacturer behind it is the challenge. After all, the manufacturer's qualifications, technical reliability, and ability to adapt to the special scenarios of the museum directly determine the quality of the subsequent services. Especially for international museums that receive global visitors, choosing the right manufacturer requires a critical eye.   In the field of museum wireless tour guide devices, the Yingmi brand under HEFEI HUMANTEK. CO., LTD.a technology information company, has been a well-established brand for many years since its establishment in 2007. Yingmi has focused solely on making tour guide devices since then. Its products have passed hard certifications such as EU CE and RoHS, and are shipped to various parts of Europe, America, and Asia on a regular basis. Large museums like Henan Museum and Guizhou Provincial Museum, as well as high-end events such as the International Museum Forum, all use its equipment. Yingmi has served over 4,000 museums worldwide, firmly establishing its reputation based on its solid track record.   When choosing a museum wireless tour guide device manufacturer, you must pay close attention to these hard indicators.   Indicator 1: Compliance certifications must not be lacking. Special attention should be paid to international exhibitions.   Whether it's foreign museums or those in China that receive international visitors, they place great importance on product compliance - if the product fails to pass the certification of the target market, even the most advanced equipment won't be able to enter. Reliable manufacturers have already obtained all these certifications, such as EU CE certification and RoHS environmental protection certification. These two are the "passports" for products to enter Europe. Yingmi has been engaged in foreign trade business for a long time and knows the pain points of international customers. All museum series products have passed EU double certification, as well as Chinese CMA and CNAS dual testing. Now when shipping to countries like France, Germany, and the UK, customs clearance is smooth without any concerns about compliance issues.   Indicator 2: A good manufacturer must be able to solve the special difficulties of the museum   The museum environment is extremely special: the exhibits are closely packed in the exhibition hall, multiple teams are visiting simultaneously, and quiet viewing is required. This means the tour guide device must be resistant to interference, not cause noise crossover, and be able to provide precise explanations. If the manufacturer only uses a universal model device to deceive, it will not be able to solve the problem. For example, in a densely-packed exhibition hall, it is necessary to avoid the situation where "while listening to the explanation of this exhibit, another one suddenly comes up". When facing tourists from different countries, the language switch should be convenient; when multiple teams are visiting, even if tourists are scattered taking photos, they should still be able to hear the explanation clearly. Yingmi has thoroughly understood these pain points and has optimized each product specifically to adapt to the needs of museums.   Indicator 3: Reliable after-sales and production capacity, and long-term use is reassuring   Museum tour guide devices are used every day, and there will inevitably be wear and tear. If the after-sales service is not up to par, it will only delay operations. Especially for foreign customers, they are most afraid of equipment breaking down and being unable to contact anyone, or having to wait for half a month for repairs. Additionally, large museums often purchase dozens or hundreds of units at a time, and if the manufacturer's production capacity is insufficient, it will not be possible. Yingmi has its own SMT soldering factory with 4 automated production lines. Even for large orders, it can deliver on time. The after-sales service is more considerate, with 24-hour multilingual customer service online. If there are quality issues with the equipment within 3 months, it can be replaced directly. For repairs within one year, it is free of charge. If two repairs are not satisfactory, a new one will be replaced. If the equipment of foreign customers breaks down, they can get it repaired internationally within 10 days. If they urgently need it, they can also get a spare device.   Yingmi: A manufacturer specializing in museum audio guides. Its advantages lie in its innovative ideas.   Yingmi has been recognized by so many museums not through advertising, but by meeting the technical, product and service requirements of each museum.   Strong qualifications: Years of accumulation, honors and certifications are all real.   Yingmi has been in the audio guide industry for many years, and its qualifications are definitely outstanding in the industry. Not only do it have titles like National High-tech Enterprise and Big Data Enterprise, but it has also passed ISO9001 and 4001 certifications. It holds many utility patents and software copyrights, which itself indicates strong enterprise strength. Over the years, besides serving 5A scenic spots and national museums in China, it has also appeared on several CCTV programs, and even became the designated audio guide equipment for international museum high-level forums. The reputation is built through actual services.   Technology: Specifically solves the problems of museum audio guides   Yingmi's technology does not play tricks. It is all aimed at solving the actual problems of museums. For example, its unique digital filtering and noise reduction technology can filter out the noise in the exhibition hall and the interference from other equipment. Even if several teams are visiting simultaneously, there will be no interference, and the audio of the guide can be heard clearly. The lithium battery management technology used not only has a long battery life but is also explosion-proof, meeting the safety requirements of museums. There is also a multilingual sharing platform, which is very convenient to switch languages. Whether it is mainstream languages or minority languages, it can be easily adapted.   The products are very practical: Museum-specific, covering different scenarios   Yingmi did not create a "one-size-fits-all" universal model. Instead, it developed a complete set of products based on the different needs of museums. Whether it is independent travelers, group visits, or exhibition areas with dense exhibits, there will be suitable equipment.   Museums often receive group tourists, and Yingmi's E8 team guide system is particularly suitable. The receiver is only 25 grams, with an earpiece design that does not distinguish left or right ears, and tourists will not feel uncomfortable after wearing it for a long time. The transmission distance can reach 200 meters. Even if tourists are scattered for taking photos, they can clearly hear the guide saying "There is a key exhibit ahead" and "Be careful of the steps below". It uses U-band high-frequency technology, with extremely strong anti-interference ability. Even when multiple teams are giving explanations simultaneously, they will not affect each other. If the guide gets tired, they can store the explanation words in advance and play them directly, saving a lot of trouble.   For museums with many independent travelers, the M7 neck-mounted guide machine can be chosen. The neck-mounted design is very lightweight, only 50 grams in weight. Tourists can wear it on their necks, taking photos and viewing exhibits without any delay. When they reach the exhibit area, they can automatically play the guide without pressing any buttons. The battery life can last for 16 hours, and there will be no problem even if it runs out of power. The storage box is made of all-aluminum material and can hold 30 devices, and it is also shockproof. It is very convenient for museums to organize equipment when cleaning.   Many museums choose it, and its strength is the most reliable   Over the years, Yingmi has relied on its solid strength to gain many "fans" from museums. National-level major museums like Henan Museum, Guizhou Provincial Museum, and China National Ethnic Museum, as well as local characteristic museums like Zhouzhuang Museum in Suzhou, all use its audio guides. International museum high-level forums also specify the use of Yingmi's equipment. Being recognized by so many professional customers is more persuasive than any advertisement.   FAQ   Q1: What languages does Yingmi's audio guide support? Can minority languages be customized? A1: The default includes English, French, German, and Japanese, which are the 8 mainstream languages. If the museum has any needs, minority languages like Arabic and Portuguese can also be customized. Switching languages is extremely simple. Moreover, the machine remembers the language you used last time and will automatically switch to it upon startup, without the need for repeated adjustments.   Q2: Has the equipment passed the EU certification? Can it be used when exported to Europe? A2: All the interpreters have passed the EU CE and RoHS certifications, fully meeting European standards, and there is no problem for export.

When many foreign customers purchase one-to-many wireless audio guide devices, they are often puzzled by the question "Which one is better?" - They are worried that choosing a cheaper one might cause crosstalk and battery life failure; choosing a more expensive one might mean wasting money and worrying about incomplete certifications and difficulties in customs clearance. In fact, to judge whether a one-to-many wireless audio guide device brand is good or not, the core lies in four points: how strong is the anti-interference ability, can the battery life meet the requirements, is the multi-language compatibility suitable, and is the international service available.   Ⅰ. First, understand: What are the core standards for a "good" one-to-many wireless audio guide device?   The core of the one-to-many mode is "one main speaker, multiple listeners". It seems simple, but it particularly tests the brand's strength. For foreign customers, a good brand must hit these four key points; missing any one is not reliable.   1. Anti-interference capability: No crosstalk even when multiple teams are on the same stage   Whether it's international exhibitions, scenic area team reception, or enterprise factory visits, it's likely that multiple teams will use the audio guide device simultaneously. If the anti-interference is poor, the audience of Team A can hear the explanation of Team B, and the scene will be completely chaotic. This is the most frequently reported pain point by foreign customers, and it is the primary criterion for judging the brand's strength.   2.Battery life and durability: Can it last throughout the entire day of high-intensity use   International conferences and large exhibitions usually last for a whole day or even several days. Good audio guide devices must be able to "charge once, last the entire day", and be able to withstand frequent use. If it requires frequent charging or breaks down after a few uses, it will only cause delays.   3.Multi-language and international compatibility: Can it be used right out of the box, without additional hassle   Foreign customers are most concerned about "compatibility issues": Can it support their own languages? Is the voltage universal worldwide? Does it have international certifications such as EU CE or RoHS? If these cannot be met, even the best equipment can only be stored in the warehouse.   4.After-sales and service: Can it be trouble-free when used internationally   If the equipment breaks down abroad, if the after-sales service is not available, it will directly become "a pile of scrap". A good brand must have a complete international service, such as remote guidance for repairs, quick shipping for repairs, and multi-language technical support. There is no fear of communication barriers.   5.Why can Yingmi stand out? It meets the "good brand" standards   Yingmi was chosen for major events such as the SCO International Judicial Conference and the International Museum Senior Forum, and has been exported to dozens of countries worldwide for a long time. The core reason is that it has achieved the ultimate perfection of the "good brand standards", and each point meets the needs of foreign customers.   Ⅱ.Anti-interference black technology: Even when multiple teams are on the same stage, they can "each hear their own"   Yingmi's one-to-many wireless audio guide device is fully equipped with advanced anti-interference technology. For example, the popular E8 team explanation system uses U-band high-frequency radio waves + 4GFSK signal modulation technology, which can open 200 independent channels. Even if 100 teams are using it simultaneously in the same area, there will be no crosstalk.   Even more impressive is that its communication range can reach 200 meters. Even in large factory workshops or open scenic areas, the audience can move freely without losing sound. At the 2018 SCO Supreme Judicial Conference, multiple delegations from several countries visited simultaneously, and they used Yingmi equipment, with zero crosstalk and zero sound loss. The organizers directly stated that "the stability exceeded expectations".   1.Battery life and durability: No pressure for high-intensity use throughout the day   Yingmi has never let customers down in terms of battery life. The E8 series has a transmitter battery life of more than 15 hours and a receiver battery life of 8-10 hours. Even if they use it for a whole day of meetings and multiple teams' receptions, they don't need to charge in the middle. If it needs to be used for a long time, it can be charged in batches with its metal contact charging box, which is fast, safe, and also has an ultraviolet disinfection function, making it convenient and hygienic. Yingmi has its own SMT assembly factory, enabling independent production of PCBA, with full control throughout the R&D to production process. Each piece of equipment undergoes 5 strict tests including high temperature, low temperature, and vibration. Even when used in a noisy factory environment or in windy outdoor conditions, it is unlikely to malfunction.   2.Full international compatibility: Use it directly, no clearance pressure   Yingmi has already considered all compatibility details for foreign customers: All one-to-many audio devices have passed EU CE and RoHS certifications, and have also undergone bilateral standard testing by China's CMA and CNAS. They can be smoothly cleared for export to most countries in the world, and complete certification documents can be provided. The charging module supports a wide voltage input range of 100V-240V. Whether it's 220V in Europe or 110V in America, just plug it in and it can be used. No additional converters are needed.   In terms of multilingual support, it is more flexible. It is equipped with the HM8.0 multilingual sharing platform, with a standard configuration of 8 mainstream languages, and small languages can be customized infinitely. Whether it's Arabic, Thai, or the less common Hungarian, as long as audio or text is provided, the sound quality algorithm can be optimized to accurately reproduce the most authentic pronunciation details, perfectly adapting to international scenarios.   III. How to choose in different scenarios? Yingmi's popular models precisely match   A good brand not only needs strong comprehensive strength, but also needs to be able to adapt to different scenarios. For the common needs of foreign customers, these several Yingmi popular models can directly fit:   1. Large international conferences, VIP receptions: Choose the E8 team explanation system   This is Yingmi's "star model", specifically adapted for high-end scenarios. The transmitter supports manual explanation and playing pre-stored explanations, and can also be connected to audio devices such as mobile phones and pads. The main speaker doesn't need to repeat explanations, and it is easy and efficient; the receiver has in-ear and ear-strap options, with the lightest weight of only 18g, comfortable to wear, and has a high appearance level.   It also supports dual-speaker function, suitable for two main speakers to alternate speaking, and can easily handle multilingual meetings. Whether it's the Shanghai Cooperation Organization conference or the Bentley car exhibition, it has been used for explanation services. It can hold high-end occasions perfectly.   2.Scenic spots, museums, multi-team reception: Choose the 007B automatic sensing + one-to-many combination   If scenic spots and museums require both team explanations and self-service visits by tourists, this combination is perfect. 007B supports automatic sensing and digital point-to-play, and tourists can trigger explanations automatically when visiting freely, and switch to one-to-many mode when receiving the team. One transmitter can connect countless receivers.   It is equipped with a 2.8-inch true-color screen, with a friendly operation interface, and elderly tourists can also use it easily; it can store multiple speech texts, and the multilingual switching is convenient. Scenic spots such as Suzhou Taihu Lake and Guizhou Xiaoshi Ancient Town are all using it. It doesn't have any pressure when receiving multiple teams every day.   3.Small meetings, temporary activities: Choose the lightweight E8 portable model   If the requirements are simple, such as small seminars or temporary exhibitions, the lightweight E8 portable model is enough. It weighs only 68.7g, convenient to carry; it supports one-to-many explanations, has a memory function for channels, and will automatically match next time without repeated debugging; it charges quickly, and can meet the needs of half a day with short-time charging, with extremely high cost performance. IV. To conclude frankly: Choosing the right brand is more important than choosing the right model   For foreign customers, choosing a good one-to-many wireless explanation device is essentially choosing "reliability" - reliable quality, reliable compatibility, and reliable after-sales service. Yingmi has used years of industry experience, from independent production to international certification, from technological research and development to cross-border services, every step is based on the needs of customers.   Whether it's large international conferences, scenic spots and museums, or enterprise factories and small-scale activities, Yingmi has corresponding one-to-many solutions. There's no need to worry about "which one is better". Instead of spending time making mistakes, it's better to directly test Yingmi's samples - whether they are good or not, you'll know after trying them. Reliable brands never hesitate to prove themselves to customers.   FAQ   Q1: Can Yingmi's multi-user wireless guide device be exported to our country?

When many foreign customers come to inquire about wireless audio guides, they always ask the same question: "Which one is the best for us?" In fact, there is no absolutely "best" one; only the one that is most suitable for the scenario. Whether it's for scenic area reception, museum guided tours, corporate visits, or large-scale conferences, choosing the right wireless audio guide can double the experience; if not, either the sound quality is poor and you can't hear clearly, or the anti-interference is insufficient, which only adds to the confusion.   Yingmi has grown from its establishment to a national-level high-tech enterprise. Its products have been exported to dozens of countries such as France, Germany, and Malaysia, and it has also served high-profile occasions like international museum forums and SCO meetings. Today, based on actual scenarios, we will recommend several Yingmi wireless audio guides to you. No matter what your needs are, you can find the right one.   Understand first: When choosing a wireless audio guide, customers should focus on these 3 points   The first point: It must have international certifications, making export customs clearance effortless   This is the most basic and crucial point. If there is no compliant international certification, the product may not pass customs clearance when transported to the local area. Yingmi started its foreign trade business as early as 2009, and all products have passed EU CE, RoHS environmental protection certifications, as well as domestic CMA and CNAS dual-standard tests. Whether exporting to Europe or Southeast Asia, customs clearance is very smooth, and there is no need to worry about certification issues extra.   The second point: Multi-language + scenarios, no need to switch devices repeatedly   Most foreign customers need to provide services to tourists or clients from different countries. Multi-language functionality is indispensable; moreover, it may be used for scenic area guided tours as well as corporate receptions. Strong equipment adaptability is very important. Yingmi's many models support multi-language switching and can be customized with languages. Some models can store multiple sets of narration words, which can be used in scenic areas, museums, and corporate exhibition halls.   The third point: There is after-sales support, and overseas use is not a problem   If there are issues with the equipment when it is used abroad, if the after-sales service is not in place, it can be very troublesome. Yingmi has the "9G Full Lifecycle Service". It responds within 90 seconds before sale and can provide free samples for testing; after-sales support offers remote technical guidance. If on-site maintenance is needed, it can coordinate cross-border services. For example, it has previously provided cross-border installation services for the Xiangkun Temple Scenic Area in Vientiane, Laos. The service capability is very reliable.   Choose by scenario: These Yingmi audio guides cover most needs   Scenario 1: Scenic area/museum team reception - K8 team audio guide system, lightweight, durable, and convenient   Whether it's a 5A scenic area or a large museum, the team reception is most concerned about "clearness, anti-interference, and good management". Yingmi's K8 team audio guide system fully meets these requirements. The receiver is an ear-catching earpiece design, weighing only 22 grams. Tourists won't feel tired after wearing it for a day, and it is non-intrusive earpiece design, avoiding the risk of multiple people sharing. Its anti-interference ability is particularly strong. It uses the 790-830 MHz high-frequency band for transmission, avoiding interference from mobile phones and radio stations. Even if multiple teams are giving guided tours at the same scenic spot, they can each give their own tours without disturbing each other. The most thoughtful feature is the automatic frequency matching function. After the transmitter is turned on, the receiver does not need to manually change the channel; it automatically matches, and the tour guide doesn't need to spend time teaching tourists how to use it, saving a lot of trouble.   The battery life is sufficient, and after charging, it can be used continuously for 7-8 hours, fully covering the reception needs of the scenic area throughout the day. After the tour, it is also convenient to tidy up the equipment. The dedicated contact-type charging box has a metal shell, safe and without any hidden dangers. It can charge multiple devices at once and can be directly stored, without the need to find a separate place to store it.   Scenario 2: Independent travelers/multi-language needs - M7C self-guided tour machine, speak wherever you go   Nowadays, many scenic areas need to provide services to independent travelers, especially foreign independent travelers. Multi-language self-guided tour machines are indispensable. The Yingmi M7C self-guided tour device is undoubtedly the top choice for such scenarios. It employs advanced RFID positioning technology. When tourists carry it to the vicinity of the explanation points, without any operation, it will automatically play the corresponding explanations, achieving "where you go, where it explains".   It supports free switching among 8 languages and has language prompt sounds. The next time it is powered on, it can automatically restore the previously selected language. This makes it particularly convenient for foreign tourists. The battery life is also very impressive, with standby time not less than 11 hours. Even if tourists spend the entire day exploring, there is no need to worry about running out of power. What's more, it also supports team explanation mode. If a small team needs an explanation temporarily, they can switch the mode and use one device to meet both needs.   In scenarios with dense exhibits and limited space, such as folk custom exhibition halls in scenic spots, it also supports touch mode. A light touch on the touch tag can precisely play the explanation, completely solving the problem of interference from close-range sensing. The accessories are also very complete, including a dedicated aluminum alloy storage box, which is convenient for storage and management in scenic spots, and an optional charging box with ultraviolet disinfection function, ensuring better hygiene.
