When foreign customers purchase wireless guide devices, the biggest concern they have is that they might malfunction at critical moments - several teams explaining simultaneously would suddenly have interference and chaos; while wandering outdoors, the signal would drop and there would be no sound; after using for half a day, the device would run out of power and shut down, or even the equipment used daily would malfunction after just a few days. For scenic spots and museums, the stability of the guide device directly affects the visitor experience, and if it fails, it could even damage their reputation. After years of experience in this industry, I have seen too many cases where companies got into trouble due to unstable equipment. If we talk about brands that can truly stand firm on stability, Yingmi definitely deserves a place in the list. After 15 years of deep development, it has become the preferred choice for many customers around the world.
How to determine if a guide device is stable? Look at these three key points.
For foreign customers, "stability" is not just a slogan; it must be truly felt. A reliable guide device must meet these three requirements: strong anti-interference ability, no interference even when multiple teams use it together; long battery life, no need to recharge repeatedly throughout the day; durable material, not prone to damage when used every day. These three points are exactly Yingmi's strongest advantages.
Core 1: Super powerful anti-interference, no interference even when multiple teams are on the same stage
Whether it's several teams visiting simultaneously in scenic spots or multiple exhibition halls opening simultaneously in museums, interference is the most annoying problem. Yingmi has solved this pain point very well, relying on two core technologies: one is its own-developed SOC embedded integrated digital noise reduction technology, which can filter out crowd noise, wind noise, and other noises, even in noisy environments with many people, it can be heard clearly； the other is digital secondary frequency anti-interference technology, combined with a 200k ultra-small channel bandwidth, different teams can use their own channels without interference. Even if 20 teams are crowded in the same scenic spot, there will be no interference or mixed signals.
More importantly, Yingmi's guide devices use the 860MHz-870MHz high-frequency band, which is much more resistant to interference than ordinary low-frequency devices, and can achieve lossless sound transmission, with a maximum transmission distance of 280 meters. Whether it's the open scenic spot paths or the multi-walled museum exhibition halls, the signal can be fully covered, and there will be no "lose sound after walking two steps" embarrassment.
Core 2： Long battery life, no need to charge frequently throughout the day
For scenic spots and museums, charging dozens or hundreds of devices every day is very troublesome, and devices with poor battery life may even lose power halfway, causing operational delays. Yingmi is equipped with PMU safe intelligent lithium battery power management technology, not only has a long battery life, but also is explosion-proof and overcharge-proof, very safe. The battery life of different models has been precisely calculated, and it can fully withstand a full day of use, without the need to rush to recharge every day.
Core 3： Durable material, not prone to damage even with frequent use at high frequencies
Scenic spots and museums' guide devices are used hundreds of times every day, and if the material is not durable, the shell may crack, and the interface may loosen. Yingmi is the original manufacturer, with 4 automated SMT production lines, it strictly controls quality from chips to shells. It uses high-strength lightweight materials, which are both lightweight and shock-resistant. For example, the shell of the receiver has undergone several wear resistance tests, even if it is placed in a charging box and repeatedly plugged and unplugged every day, it will not peel off or deform; the interface has been designed with waterproof and dustproof functions, and can be used normally in outdoor scenic spots with small rain or dusty environments.
Why can Yingmi achieve "global recognition of stability"?
The stability of Yingmi is not a matter of luck, but is strictly controlled at every step from research and development, production to quality control. As the original manufacturer, it can precisely solve industry pain points, relying on its hard power.
Core Technology： Self-developed core technology, ensuring stability from the source. Yingmi holds a number of utility patents and software copyrights, and its core technologies are all developed independently. Unlike some small brands that rely on purchased technologies, they cannot promptly optimize when encountering problems. For instance, to solve the issue of unstable outdoor signals, the R&D team spent two years testing chips, and finally chose a high-quality chip with long lifespan, low power consumption, and strong anti-interference capabilities; for multilingual scenarios, they also developed the HM8.0 multilingual sharing platform, and when switching languages, there would be no situation of signal interruption or poor sound quality.
Global multi-scenario practical verification, stability speaks for itself
Whether it's user-friendly or not, practical experience shows the truth. Yingmi's products have been tested in various extreme scenarios worldwide: in the Xiangkun Temple scenic area in Vientiane, they can withstand the tropical environment with high temperature and high humidity; in the Taishan Dai Temple scenic area, they can meet the signal requirements for outdoor open spaces; at international museum high-level forums, they can ensure stable transmission for multilingual simultaneous interpretation; in the SCO meetings, they can guarantee zero malfunctions in high-level receptions. These challenging scenarios can all be handled, and they are more persuasive than any advertisement.
Different scenarios stable selection: These two Yingmi models are worth choosing without hesitation
Yingmi has several high-stability products for different scenarios. Foreign customers don't need to guess blindly; they can choose based on their own needs.
Scenic area/conference first choice: E8 team explanation system, stable as a mountain in multiple teams competing
E8 is Yingmi's star model, specially designed for multi-team and high-frequency usage scenarios, with full stability. It is an integrated design, weighing only 16 grams, and it hardly feels heavy when held in hand, yet it is equipped with a complete anti-interference technology - digital secondary frequency conversion + SOC noise reduction, and there are 200 channels available. Even if multiple teams use it in the scenic area simultaneously, each team locking their own dedicated channel, there will be no interference.
The battery life is also very powerful. The transmitter can last for 15 hours at a time, and the receiver can last for 8-10 hours, which is completely sufficient for the scenic area's full-day operation. The contact-type charging box is made of metal, safe and won't catch fire, and it also has ultraviolet disinfection function. It can charge 36 or 48 devices at once. Put the equipment in it at night and take it out the next day to use, it's very convenient. Its transmission distance can reach 200 meters. Even when tourists are scattered for taking photos and free activities, they can clearly hear the explanations from the tour guide, without any signal interruption.
Whether it's scenic area team reception, enterprise exhibition explanation, or large-scale international conferences' mobile simultaneous interpretation, E8 is reliable. Now, 5A scenic areas like Suzhou Taihu Lake and Jiangxi Longhu Mountain are all using this model.
Museum/exhibition first choice: C7 touch + induction guide machine, precise and stable in dense scenarios
In museums and exhibition halls, the exhibits are close together, and ordinary induction explanation machines are prone to triggering and interference. Yingmi C7 just solves this problem. It has two usage methods: when the exhibits are dense, gently touch the label beside the exhibit (NFC touch) with the guide machine to accurately play the explanation; when the exhibition hall is open, use the automatic induction mode, and it will automatically trigger when you approach the exhibit, flexible and stable.
C7 can store multiple explanations and supports multilingual customization. By default, it has 8 mainstream languages, and the signal is very stable when switching, without lag or audio interruption. It can last for 10 hours with one charge, and it will automatically remind when the battery is running low, so there's no need to worry about shutting down halfway; the shell is made of high-strength ABS material, resistant to drops and abrasion, and even if the tourists accidentally drop it on the ground, it won't easily break. The inductive labels used with it are made of long-life low-power chips, and one battery can last for 3 years, without frequent replacement, saving a lot of trouble.
