Last late autumn, an international museum forum was held in a provincial capital city with great enthusiasm. The exhibition hall was packed to the brim, and 12 countries’ participating teams had to visit and exchange at the same time. The organizers were really worried before: as soon as the traditional loudspeakers were turned on, the buzzing noise was a headache. The explanations of different teams were mixed together, and the audience in the back row couldn’t hear a single detail at all. The foreign friends’ demands for minor languages were even more helpless. Later, with a try-it-out attitude, they chose the team tour guide system of Yingmi. The result was far beyond expectations – the main speaker just spoke at a normal speed and in a soft voice, and the audience a hundred meters away could hear clearly. Eight teams visited in parallel in the same space, and their voices did not interfere with each other. Listeners of minor languages could also get all the content simultaneously with the help of the supporting equipment.
In fact, not only this international event, but also well-known venues and scenic spots like the Henan Museum and the Taihu Scenic Area in Suzhou have long solved the long-standing problem of one-to-many tour guide system with similar equipment. There are all kinds of wireless audio guides on the market now, with varying prices and functions. So, which one is truly reliable? Today, starting from the actual scenarios we use and drawing on 18 years of experience in this industry, I’ll tell you exactly what makes Yingmi so good.

I.The Hassle of one-to-many Explanations
Whether it’s leading a team to visit a museum or scenic spot, or a company receiving clients for an inspection, the trouble of one-on-one explanations always comes into play. Have you ever fallen into the same trap?
The tour guide spent a long time Shouting at the top of his voice, but when he turned around, he was drowned out by the honking of the group beside him. The tourists’ ears were in a mess. Not to mention being able to clearly understand the historical anecdotes and product details in the explanations, they didn’t even have the mood to have a good look around. Especially in places like museums and art galleries that require a quiet experience, the honking of horns is particularly jarring. It not only disturbs others but also spoils the cultural experience atmosphere that should be immersive.
There is also the long-standing problem of distance. The speaker walks in front, and the audience at the back can only follow from a distance. The sound is not clear, and gradually they can’t keep up with the pace of the group. In the end, they just wander around aimlessly on their own. If you are in an outdoor scenic area or a multi-story exhibition hall, if you are a little farther away, there will be a situation where the sound is disconnected and blurred. By the end of the visit, tourists won’t remember much useful information, and the explanations seem to have been in vain.
During the peak tourist season, popular scenic spots and museums have to receive dozens of groups in a day. According to the traditional model, the routes and times can only be forcibly staggered. Tourists have to queue up at the same place for half a day, and it is also difficult to arrange the venues. The reception efficiency has never been improved. Moreover, most traditional devices are large and heavy. The presenter is exhausted, and it is troublesome for the team to collect, distribute and manage them uniformly. The battery life is also not satisfactory. Often, the battery runs out halfway through the tour, which directly disrupts the entire presentation plan.
Nowadays, international exchanges are becoming more and more frequent. Many venues receive foreign teams. However, it is very difficult to find interpreters in minority languages, and hiring professional translators is too costly. Traditional equipment simply cannot synchronize multilingual content. Foreign tourists can only take a cursing look and take some photos, and they are unable to deeply understand the cultural connotations behind them. International reception always feels a bit lacking.

Ii. Yingmi’s Solution for one-to-many Explanations
Among a bunch of one-to-many wireless tour guide system, the team tour guide system of Yingmi has become the first choice for museums, scenic spots and enterprises. It is not because of its strong advertising, but because it can truly solve the troubles we encounter. This is also the confidence that has enabled it to deeply engage in the industry for 18 years.
1.Noiseless and interference-free
The most reassuring feature is its characteristic of being “noise-free and interference-free”. It uses exclusive wireless transmission technology. The speaker wears a lightweight transmitter and the audience holds a small receiver. The sound is directly transmitted to the receiver without spreading out. This neither disturps the people around nor causes frequency crossover among multiple teams. Even if several teams are active in the same exhibition hall or the same scenic area, their explanations will not interfere with each other. This is also the core reason why large venues such as the International Museum Forum and Henan Museum have always recognized it.
2.Long transmission distance
The transmission distance is also more than sufficient. Whether it is the open terrain of outdoor scenic spots or multi-story exhibition halls, within a range of 100 meters, everything can be heard clearly. Listeners in the back row do not need to move forward deliberately to capture every detail of the explanation. Moreover, the device is particularly lightweight. The transmitter and receiver can be carried in your pocket or hung on your body without taking up much space. Even if you carry it for a long time, it won’t feel heavy. The battery life is also very durable. After a whole day of team activities, you don’t need to charge it in the middle, and there’s no need to worry about power outages or chain breaks at all.
3.Multi-team collaboration is convenient
It is also particularly convenient when multiple teams collaborate. The system supports free switching among multiple channels. Venues and scenic spots can plan channels in advance based on the number of teams on that day. Different teams use their own dedicated channels, eliminating the need to struggle to stagge routes and times. The reception efficiency is directly improved. Just like the Taihu Lake Scenic Area in Suzhou, during the peak season, it receives over 20 tourist groups every day. Previously, the time arrangement had to be gradually staggered. Now, with this system, the reception is not chaotic at the same time, and the reception capacity has increased by more than 30% compared to before. The feedback from tourists is also getting better and better.
It can be used in many places, not only in common scenarios like museums and 5A scenic spots. When enterprises receive clients for inspection, they can use it to explain the layout of the factory area and the production process. The sound is concentrated and does not spread, which is both professional and does not affect the normal production of the workshop. In theme parks, tour guides use it to explain the background of scenic spots and precautions for visiting, which will not spoil the visiting atmosphere of the park. During study Tours, the teacher’s explanations can clearly reach each student’s ears. Even if the queue is a bit long, it can still ensure the teaching effect. It can be called a “universal explanation tool”.
If it is necessary to receive foreign groups, it can also be combined with Yingmi self-service tour guide system to directly achieve real-time multi-language explanations, covering popular languages such as English, Japanese, and Korean. There is no need to spend extra money to hire tour guides of minor languages. This not only reduces the reception cost but also enables foreign tourists to have a deeper understanding of the culture and products. This is also the key reason why its products can be exported overseas for a long time and be recognized by international customers.

III. When choosing an audio guide, service is more important than the product itself
By the way, when choosing this kind of one-to-many wireless audio guide, it’s not enough for the equipment to be user-friendly. The subsequent service is the guarantee for long-term use – after all, the installation and debugging of the equipment, later maintenance, and emergency handling directly affect the smoothness of daily use. Yingmi has been able to establish a firm foothold in the industry by providing reliable and trustworthy services from start to finish.
1.Pre-sale: Tailor-made, no blind recommendations
Their consultants won’t make blind recommendations. Before the sale, they will ask you in detail about your actual situation: Is it for museums or scenic spots? How many people are there usually in a team on a regular basis? Should multiple languages be supported? Are you planning to make a long-term purchase or a short-term lease for emergency use? After asking these questions clearly, we will tailor a solution based on your specific needs. For instance, for small museums, a combination of “team tour guide system + a few self-service tour guides” would be recommended, which is both sufficient and not wasteful. Large scenic spots are equipped with self-service tour guide machine rental systems, making it convenient for individual tourists to rent and use them at any time. If a company only has short-term reception needs, it can also provide equipment rental services. There is no need to invest a large sum of money at one time, which is particularly considerate.
2.During the sales process: Professional implementation, hands-on guidance
After the equipment arrives, the technical team will proactively visit the site for installation and commissioning, conducting tests one by one to ensure that each piece of equipment can be used normally. Moreover, it will teach you step by step how to operate, how to switch channels, and how to manage the equipment inventory. Even staff members who know nothing about electronic devices can become proficient after following and learning for about ten minutes. If it is a large venue or scenic area, there will also be special training on the management of batch equipment, teaching you how to quickly allocate equipment to the team, how to count usage, and how to carry out daily maintenance, helping you sort out all the subsequent management troubles.
3.After-sales service: Nationwide coverage and prompt response
The after-sales service is even more worry-free. If the equipment malfunctions, just make a phone call and the after-sales team will respond within 24 hours. In case of emergency, they can even come to your place for repair, ensuring no delay in normal use at all. Moreover, whether it is domestic or overseas customers, the prices and service standards are the same, and there will be no situation where “treatment varies in different regions”. This is really very reassuring.
