During the peak season for study tours in a certain scenic area, there are student groups everywhere carrying schoolbags. Once, I witnessed with my own eyes that several teams were crowded in the same exhibition hall. Some teams were using ordinary audio guides, and from time to time, the voices of other team tour guide would pop in through their headphones. The students were frowning and repeatedly changing channels, and the guides had to shout and repeat. Meanwhile, another group of people using the Yingmi system to explain the system, whether the students were scattered to the viewing platform 200 meters away or gathered in the crowded corner of the exhibition hall, everyone could listen to the explanation quietly and clearly. There was not a single instance of crossowing or disconnection throughout the entire process.
A friend of mine who works in corporate tour reception once joked that the battery life of the tour guide he used before was too poor. Once, over 30 devices ran out of power simultaneously during the visit, and the originally two-hour factory tour was interrupted for 15 minutes. Later, we switched to the equipment of Yingmi. From 9 a.m. to 5 p.m., we worked non-stop for 8 reception sessions. The equipment never broke down throughout the process. After work, we charged it in batches and it was still usable the next day. These real situations all indicate that the wireless audio guide used by the team is not just about “being able to make sound”. Stability, peace of mind, and suitability for the team size are the most core requirements.
I.Core Issues of the Team’s Use of Wireless Tour Guide System
1.Signal crosstalk: A major headache for communication among multiple teams running in parallel
Whether it’s a museum, an exhibition or a popular scenic spot, as long as there are multiple teams working simultaneously, ordinary audio guides can easily “move around”. Team A was giving a history lecture. Suddenly, a product introduction popped into Team B’s headphones, leaving the audience completely confused. The tour guide also had to repeatedly stop and repeat. Especially in a confined space, Wi-Fi and Bluetooth signals are crowded together, and this crosstalk problem is even more severe, completely disrupting a good schedule.
2.Insufficient battery life: Power outage during the journey greatly affects the pace
Most team activities last for half a day or even a whole day. A regular audio guide can be used for at most 3 to 5 hours, which is far from enough. Several times, I saw the tour guides in the scenic area carrying spare chargers and asking tourists to queue up for charging during the visit, which completely disrupted the originally smooth visiting rhythm. For scenic spots and enterprises that need to receive visitors frequently, charging the equipment and managing the charging cables every day is also an additional hassle.
3.Wearing discomfort: Wearing it for a long time is too painful
There are elderly people and children in the team, and their ear shapes are also different. Some of the audio guides are made very heavy and hard. Wearing them for just one hour will cause ear pain. There are also some in-ear types that are particularly awkward for people who wear glasses to use. They are prone to sweating in hot weather and hygiene is not guaranteed. In the end, many people simply take them off and no longer use them.
4.Complex operation: It’s too difficult for the temporary team to get started
Most study tours and business inspection teams are formed on the spur of the moment, and many of them have never used audio guides before. If the equipment still requires manual frequency adjustment and pairing, the staff will have to teach each one, which not only wastes time but also is prone to errors. When encountering foreign tourists or the elderly, it takes half a day just to teach them how to operate, which particularly affects the experience.
5.Blurry sound quality: It’s impossible to hear clearly in a noisy environment
In noisy places like factory workshops and scenic area squares, the sound quality shortcomings of ordinary audio guides are immediately exposed. The ambient noise drowned out the explanation. The audience had to press their headphones close to their ears to barely make out the sound, and all the crucial information was leaked. Especially when explaining professional knowledge or historical culture, if you don’t catch a single sentence clearly, you won’t be able to keep up with the rest.
6.Insufficient channels: Multiple teams can only work at staggered times
During the peak season, many exhibition halls and scenic spots have to receive tens or even dozens of groups in a day. The channels of ordinary tour guide devices are only a few, which can only allow groups to carry out activities at off-peak times, resulting in a very low utilization rate of the venue. Sometimes, when tourists arrive, they have to wait for half an hour before the explanations can start, which greatly reduces the experience.
Ii. Scenario-based Recommendation: Yingmi’s precise adaptation solution
1.Yingmi E8: The ideal choice for efficient collaboration among small and medium-sized teams
(1)The core advantage of E8: It is worry-free and convenient for small and medium-sized teams to use
The Yingmi E8 is tailor-made for small and medium-sized teams of 10 to 30 people. Its most prominent features are “practical, worry-free and easy to manage”. It uses the 860MHz-870MHz high-frequency band for transmission, with a signal coverage radius of up to 200 meters. Even if team members are scattered in the corners of scenic spots or exhibition halls, they can still clearly receive the signal without any situation where anyone cannot hear it clearly.
In terms of battery life, the E8 is really impressive. The transmitter can last for 15 hours on a single charge, and the receiver can also last for 8 to 10 hours. Throughout the day’s activities, there’s no need to charge it in the middle. After the group is packed, simply place the equipment in the contact charging box. There’s no need to plug in wires one by one. Batch charging is fast and safe. The charging box also has an ultraviolet disinfection function, so it’s reassuring to share it with multiple people.
It is also comfortable to wear. The receiver weighs only 18 grams, lighter than a coin. The ear-hook design distinguishes between left and right ears. Whether you are a primary school student, the elderly, or someone wearing glasses, you won’t feel the pressure on your ears even after wearing it for a long time. The material is skin-friendly silicone, which makes it less likely to cause sweating even in hot weather. People with allergic constitutions can use it without any problem.
The operation is so simple that no teaching is needed. Press the SET key to turn on the device, and the receiver will automatically search for the signal connection. There is no need to manually adjust the frequency at all. The LCD screen on the transmitter clearly shows the channel, volume and battery level. The guide can always keep track of the device status. Even temporary volunteers can use it as soon as they pick it up.
(2) Scenario adaptation of E8: It is suitable for both study Tours and business investigations
E8 has 200 adjustable channels. Multiple small and medium-sized teams can operate in the same exhibition hall or scenic area without interfering with each other at all. Once when I visited a museum, I saw three 15-person study tour groups visiting at the same time. Each group was using a different channel. The guides spoke softly, and the students could all hear clearly. The exhibition hall was not in a mess either.
The anti-interference ability of E8 in study tours is particularly practical. With so many Wi-Fi and Bluetooth signals in the scenic area, it can still filter out noise and ensure clear sound quality. The tour guide just needs to speak normally with a lapel microphone. There’s no need to shout at the top of your voice. This not only protects your voice but also allows students to focus on listening to the explanations.
When enterprises conduct business investigations or receive small conferences, the portability of the E8 also adds a lot of points. The device is compact in size and can be stored in a dedicated storage box, making it convenient to take it out for business trips or exhibitions. The transmitter also has 4GB of memory and can pre-store 9999 segments of commentary. When there is content that needs to be repeated, just play the pre-stored audio directly, which saves a lot of trouble.
2.Yingmi K8: A stable transmission solution for large teams
(1) The core advantage of K8: Large teams can stay stable with it
For large teams of over 30 people, choosing the Yingmi K8 is definitely the right choice. Its hard power is truly top-notch. It adopts the dedicated 790-830MHz frequency band, avoiding common signal interference sources such as mobile phones and radio stations. Coupled with digital transmission technology, it can transmit stably even in crowded 5A scenic spots and exhibition sites with complex electromagnetic environments, without any sound interruption or crosstalk.
The most remarkable feature of K8 is its ability to “one-to-many”. One transmitter can be connected to over a hundred receivers, capable of accommodating up to 500 people simultaneously. It can handle scenarios such as a thousand-person study tour group or visits to large enterprises and factories with ease. Moreover, it can automatically synchronize frequencies. Once the transmitter is turned on, all the receivers can automatically match the signals. Staff members do not need to debug them one by one, saving a lot of time and energy.
The wearing design is also very considerate. The 22-gram non-in-ear ear hook will not clog the ear canal. Wearing it for a long time will not cause sweating, and there is no need to worry about hygiene issues when sharing it with multiple people. It is particularly suitable for high-frequency usage scenarios such as scenic area rental and large-scale events. Even if several groups of people are received in a day, the equipment is easy to maintain.
The sound quality is also top-notch. Through digital filtering technology, environmental noise is filtered out. Even in factory workshops, no matter how loud the machines are, the sound of the explanation can still be clearly transmitted. The transmitter can also adjust the microphone gain. The tour guide can adjust it according to their own speaking habits and the ambient noise without deliberately raising their voice.
(2) K8’s scene adaptability: It can handle both thousand-person groups and international conferences
During the peak tourist season in Tianmu Lake Scenic Area, Jiangsu Province, it is common to see large study Tours of 500 people. The students are scattered in various corners of the scenic area, all wearing K8 receivers. The voices of the tour guides can be clearly heard by everyone. Whether by the lake, on the mountain paths or in the exhibition halls, there has never been a situation where they could not hear clearly.
When visiting enterprise factories or receiving large conferences, the multilingual function of K8 is particularly practical. It comes standard with 8 mainstream languages, and niche languages can also be customized. Foreign customers do not need to find additional translators; they can understand the core information with the help of the audio guide. When paired with a lapel microphone, the voice of the guide can be accurately captured. Even in spacious workshops or large conference rooms, people in the back row can hear clearly.
In terms of equipment management, the batch charging box of K8 is extremely user-friendly. The metal casing is particularly sturdy and safe with no hidden dangers. It can charge 36 or 48 devices at a time. It adopts an intelligent charging mode and can also protect the battery life. After the tour is over, all the equipment can be put in. The next day, it can be fully charged and put into use. The staff don’t have to run around the charging cable every day, which saves a lot of trouble.
