Once in a museum, I encountered such a situation: a group of study tour teams from Europe were walking and stopping in the exhibition hall. It was obvious that they were particularly interested in the cultural relics inside, but the tour guide’s explanations were completely drowned out by the noise of the surrounding crowd. Many people frowned and looked confused. At the same time, a group of government and enterprise delegations were also visiting. Due to the channel interference of the traditional audio guides they used, they mistakenly heard “cultural relic restoration techniques” as “prices of cultural and creative products”, almost causing a misunderstanding in the cooperation.
It was not until later when the venue introduced the Yingmi wireless audio guide that all these troubles were completely solved – the study tour team, relying on its multilingual function, could clearly understand every historical detail. Even when the government and enterprise inspection team is within a range of 150 meters, they can clearly receive the explanation instructions. In fact, such a transformation is not an isolated case. Whether it is team-building activities in scenic spots, factory visits, or international exhibitions, the core of visiting activities is to enable participants to obtain information efficiently. As a key tool for transmitting information, the quality of the tour guide directly affects the effect of the activity. Among numerous brands, Yingmi has been deeply involved in the interpretation and display industry for 18 years. With its solid technical accumulation and scenario-specific solutions, it has become the preferred brand for many global visiting events.
I.Pain Points of Choosing a Tour Guide for Visiting Activities
1.The signal and sound quality problems directly make the explanation a waste of effort
The visiting scene is already complex, and the requirements for the tour guide system are actually very high. For instance, in science and technology museums with a large number of electronic devices, traditional audio guides often experience lag and crosstalk due to signal interference. When entering open scenic spots or large factories, due to insufficient signal coverage, participants in the back rows may not be able to hear the core content clearly. What is even more troublesome is the influence of the noisy environment – the roar of machines in the workshop and the noise of people in the exhibition hall can completely block out the sound of ordinary tour guides. Even if the tour guide shouts at the top of his voice, it is difficult to ensure the accurate transmission of information, and it is more likely to cause vocal cord fatigue of the tour guide.
2.The operation and management are too cumbersome, which drags down the overall efficiency of the event
If multiple teams are conducting activities simultaneously, the channel Settings of traditional audio guides are particularly troublesome and prone to conflicts and confusion. Staff members have to spend a lot of time debugging the equipment. Some devices have complex matching processes. When encountering elderly tourists or foreign participants, it is particularly difficult for them to get started, which can easily delay the progress of the activity. In addition, the storage and charging of equipment are also a burden. Scattered chargers and messy cables not only take up space but also easily lead to missed charging and equipment damage, causing many invisible troubles for event organization.
3.Insufficient battery life and compatibility make it difficult to meet diverse demands
The duration of the visiting activities varies, ranging from two or three hours to a continuous day. However, most traditional audio guides have a battery life of less than six hours and often experience power outages in the middle, directly disrupting the rhythm of the activity. Moreover, the demands for different visiting scenarios vary greatly: foreign receptions require multi-language support, study Tours demand lightweight and comfortable equipment, and large-scale conferences value multi-channel concurrent capabilities. A single-function tour guide simply cannot fully meet these demands, resulting in inconsistent activity experiences.
II.Choose the right model according to the scene
1.Small group Tours : K8 team tour guide system
For scenarios such as small-scale study Tours or internal corporate inspections, the Yingmi K8 team tour guide system can be said to be the king of cost performance. Its receiver weighs only 22 grams. The ear-hook design fits the earlobe very well. Even if you wear it all day, you won’t feel pressured. Whether it’s children or participants who wear glasses, they can all adapt easily. Moreover, it is a non-in-ear design, which is not only hygienic but also avoids the health risks brought by sharing among multiple people. It is particularly friendly to foreign teams that pay attention to hygiene protection.
When it comes to core performance, the K8 uses the 790-830 MHZ high-frequency band for transmission, which can effectively avoid signal interference from devices such as mobile phones and radios. Even in a crowded exhibition hall, the sound quality can remain clear. It also has an automatic frequency matching function. After the transmitter is turned on, the receiver can automatically match without manual adjustment. Even temporary volunteers can quickly get the job done. With a battery life of 7 to 8 hours, it can fully meet the needs of half a day to a full day of activities. The metal contact charging case that comes with it can charge multiple devices at once, achieving storage and charging in one step, which can significantly reduce the management pressure on staff.

2.Large-scale group activities : E8 team wireless tour guide system
When it comes to large-scale exhibitions, team-building activities in scenic spots, or visits by multinational companies and other multi-person scenarios, the yingmi E8 team wireless tour guide system can easily control the entire event. It supports 150 adjustable channels. Even when multiple teams use it simultaneously, there will be no crosstalk, completely solving the problem of “each talking their own thing and interfering with each other” in large-scale events. With a transmission distance of 180 meters, even if participants are scattered in an open area, they can still clearly receive the explanation content.
The body design of E8 is both high-quality and practical. The receiver weighs only 20 grams and is about the same size as a Bluetooth headset. Its fashionable and elegant shape can enhance the professional level of the event. By adopting the GFSK Gaussian frequency shift keying modulation method, it has an exceptionally strong anti-interference ability. Whether in a conference center with a high concentration of electronic devices or in a factory workshop with the roar of machines, it can achieve high-fidelity voice transmission. The accompanying charging and storage box can accommodate 48 devices, integrating charging, storage and transportation. It is particularly suitable for large-scale event organizers that need to manage devices in batches.

3.Independent travel and international reception: M7C self-service tour guide system
For groups such as individual tourists in scenic spots and foreign independent travelers, the Yingmi M7C self-service tour guide system is a good choice. It is equipped with advanced RFID positioning technology. When tourists approach the explanation point, they don’t need to perform any operation, and the device will automatically play the corresponding content, truly achieving “wherever you go, the explanation follows”. It supports free switching among 8 languages and can also remember the last language used. Foreign tourists can operate it without any obstacles, which can significantly enhance the professionalism of foreign-related reception.
In terms of detailed design, the M7C also takes into account the needs of different scenarios: in small Spaces with dense exhibits, the touch mode can be switched. A light touch on the tag can precisely play the explanation, avoiding interference from close-range sensing. The standby time is no less than 11 hours, so you don’t have to worry about battery power even if you tour all day. The accompanying aluminum alloy storage box can also be optionally equipped with ultraviolet disinfection function, ensuring better hygiene. At the same time, it supports the switching of team explanation mode. When a small team needs to explain temporarily, there is no need to replace the equipment. One machine can meet two needs.
