On the lakeside walkway of a 5A-level scenic spot, many tourists from all over the world are quietly listening to the explanations. In the exhibition halls of the museum, visitors can hear the multilingual introductions of the exhibits simply by touching the devices in their hands – all of these are made possible by reliable wireless audio guides. Currently, there are numerous brands of wireless audio guides available on the market, with their various functions and parameters making it hard to make a choice. Choosing the right one can double the audio guide experience, while choosing the wrong one may lead to annoying issues such as noise and signal failure. Among all these brands, Yingmi, which has been dedicated to the audio guide industry for 18 years, has become the favorite of more and more museums, scenic spots, and government units due to its years of technical accumulation and solid cooperation cases.
I.Avoid These Pitfalls When Choosing a Wireless Audio Guide Speaker
Whether it’s for scenic area tours, museum visits, corporate receptions, or government meetings, the main goal of using a wireless audio guide is to “hear clearly, use smoothly, and not be troublesome”. However, many users have fallen into these traps:
Either in a crowded exhibition hall with numerous exhibits, the guide speaker often malfunctions, playing the description of one exhibit when you actually want to hear about another; or when several people use it together, the noise is loud, and the speaker’s voice is drowned out, leaving the audience to only get a rough idea; or when there are many international tourists, the language support for the guide speaker is too limited to meet the needs of tourists from different countries; and the most frustrating thing is that the device doesn’t have a long battery life, running out of power after just a few hours, and then it has to be put aside; storage and charging are also troublesome, with dozens of devices piled up in a messy manner, charging is slow and prone to damage, and after a long search for customer service, no one responds.
These seemingly insignificant problems actually have a significant impact on the experience. Especially in places that require service quality, such as museums and 5A scenic spots, a reliable wireless audio guide in essence, needs to address the two core requirements of “accurate information transmission” and “ease of use”.

II.Select the Right Model for Different Scenarios: Yingmi C7 self-service audio guide system
For the pain points in different scenarios, Yingmi C7 self-service audio guide system offers a targeted solution. Whether it’s a museum with closely packed exhibits or an expansive scenic area, it can be used in any situation.
1.For Museums and Art Galleries: NFC Touch + Automatic Sensing
Most exhibits in museums and art galleries are placed closely together, and if the distance between many audio guides is too close, there is a risk of frequency interference. However, Yingmi C7 has a dual-sensing function, which precisely solves this problem. If the distance between the exhibits is small, tourists can simply touch the NFC tag card on the front of the exhibit with the lower end of the device and hear the corresponding explanation without pressing any buttons, which is very convenient. If the exhibition space is spacious, and the distance between two explanation points exceeds 5 meters, the device can automatically sense the signal transmitter and play the current area’s explanation content. You can hear it wherever you go.
Moreover, C7 can store 9999 segments of explanations, and multilingual recording is completely possible. International tourists can also choose the language they are familiar with. The weight of C7 is only 50 grams, much lighter than an egg. It is not tiring to carry it in your pocket or hold it for a whole day. The battery life can reach more than 10 hours, which is completely sufficient to cover the entire opening hours of the exhibition hall. There is no need to worry about power outages in the middle.

2.For Scenic Areas and Large Exhibition Halls: Long-distance Noise-Free
For some 5A scenic areas with long tour routes and many groups, the signal and anti-interference capabilities of ordinary audio guides are crucial. Yingmi C7 uses a carrier frequency of 860MHz-870MHz and adds wireless communication power control technology. Even if multiple teams are conducting simultaneous explanations, there will be no signal interference. The sound can be heard clearly.
The management equipment for scenic areas is also convenient. C7S has a dedicated charging box and storage box. The charging box can charge 45 devices at once, with a 220V input and 5V-20A output. It adopts an intelligent charging mode, which is fast and safe, and can extend the battery life. The storage box has an aluminum alloy frame and contains silicone grooves and sponge, which can hold 30-50 devices stably. It is not prone to damage during transportation and storage, and can specifically store charging cables and other accessories. The messy problem is solved at once.

3.For Enterprise Visits and Government Reception: Compact and Portable
When enterprises visit factory production lines or government representatives introduce exhibition halls, the audio guide not only needs to be functional but also needs to appear professional and portable. The body size of Yingmi C7 is only 82×59×12.5mm, about one-tenth the size of a mobile phone. It can be carried in your pocket and does not take up space. Moreover, it supports MP3 format and has high-fidelity sound quality at 44.1k sampling rate. Every word of the main speaker can be clearly transmitted. Whether introducing products or exhibition content, the audience can feel efficient and professional service.
