Those who do volunteer services all know that whether it’s guiding in scenic spots, receiving visitors at exhibitions or explaining in museums, the most troublesome thing is that “good content can’t be spread” – in a noisy environment, one’s voice is hoarse from Shouting, but the audience still can’t hear clearly. I want to cooperate with experts to supplement information, but I always grab the microphone and disrupt the rhythm. When encountering overseas audiences, if there is a language barrier, one can only rely on gestures. The equipment suddenly ran out of power and it took a long time to adjust the channel without getting it right. Not only did this delay the service, but it also affected everyone’s experience.

For many years, Yingmi Technology has been deeply engaged in the field of wireless interpretation, always keeping a close eye on these pain points of volunteer services. The Yingmi E8 team guide we developed doesn’t have any fancy functions. It is designed to “solve practical problems” – it is anti-interference, capable of dual narration, easy to operate, and has a long battery life. From scenic spots to exhibitions, from domestic to international, it enables volunteers to no longer be held back by the equipment and focus on telling their stories well.

I.The old equipment simply can’t handle those “annoying things” in volunteer services

Whether it’s the peak season tour guiding in 5A scenic spots or the reception at international exhibitions, the problems encountered by volunteers are more or less the same. These issues may seem minor, but they actually lower the service efficiency.

1.In a noisy environment, the explanation sounds like “mosquitoes chirping”

Popular scenic spots and exhibitions are always crowded and noisy, and the sounds from traditional loudspeakers simply “can’t get out”. Last year, Xiao Li, a volunteer at the Gulangyu Scenic area in Xiamen, led a group of 20 people to introduce the Shuzhuang garden. The loudspeaker was turned up to the maximum volume, but the tourists in the back row could only hear the words “Shuzhuang garden” and “Republic of China”. They kept asking, “Why did the owner build this garden back then?” After a one-hour presentation, Xiao Li repeated the key information no less than ten times. By the end, his voice was so hoarse that he couldn’t speak.

At the Adidas exhibition in Shanghai, volunteer Xiao Zhang was in charge of introducing the new sports equipment. The exhibition area was filled with the roar of machines and the hustle and bustle of people. The sound of a loudspeaker mingled in. A German buyer simply leaned close to Xiao Zhang and almost pressed his face to ask, “What is the shock-absorbing material of this running shoe?” ” Xiao Zhang could only slow down his speaking pace and speak at the top of his lungs one-on-one. Originally, he planned to lead 10 groups of audiences, but in the end, he only managed to complete 6 groups and was sweating profusely.

2. Wanting to cooperate with experts but always “snatching the microphone”

Often, volunteers explain the basic content and experts fill in the professional details, but with traditional equipment, only one person can explain it all the way through. Xiao Wang, a volunteer from the Henan Provincial Museum, was giving a lecture on Tang Dynasty terracotta figurines. The cultural relics expert wanted to add that “the glaze of the terracotta figurines was made of Persian cobalt”, so they had to wait until Xiao Wang finished. But by then, the audience had already shifted their attention to the next exhibit. As soon as the expert began to speak, someone asked, “Is there any other story about that terracotta figurine just now?” The rhythm on the spot was completely disrupted.

Huawei’s industrial exhibition was more typical. Volunteers were explaining the production line process, and a technician wanted to interjected, “This line saves 15 kilowatt-hours of electricity per hour.” The two took turns using one microphone. During the few seconds of pause in between, some audience members thought the explanation was over and turned to leave. The technician could only follow up to add more, which was both embarrassing and delayed.

3. Overseas audiences are “completely at a loss”, and the language barrier makes communication difficult

Nowadays, there are many international activities, and volunteers often encounter overseas audiences, but language has become a major obstacle. Xiao Chen, a volunteer at the Taihu Lake Scenic Area in Suzhou, wanted to tell foreign tourists about the fishing culture of the “Three Whites of Taihu Lake”. Without bilingual equipment, he could only use his mobile phone to translate through translation software. The tourists smiled and nodded, and finally asked the translator in a low voice, “When can we eat the silver fish he just mentioned?” Obviously, I didn’t understand the key point.

There were also Chinese volunteers at the Louvre in France. Previously, when leading international Tours, they could only speak in English. Spanish and Italian tourists couldn’t understand and could only look at the English signs on the exhibits. A Spanish tourist said, “I only understood half of the story of the Mona Lisa. What a pity!”

4. The equipment is “breaking down”, difficult to operate and not durable

Most of the volunteers are not from a technical background and simply can’t handle the complex equipment. Previously, some volunteers used a certain brand of audio guide. When changing exhibition areas, they had to manually adjust the channel. Pressing the wrong key would cause noise. Once, after adjusting for five minutes, the audience got impatient and left halfway. Some of the devices only have a battery life of 4 hours. They start serving at 10 a.m. and run out of power by 2 p.m. Volunteers can only borrow the devices temporarily. There is an hour in between when no one explains. The audience complains that they have come for nothing.

Ii. Yingmi E8: A Tailor-made “Explanation Assistant” for Volunteers

When we were working on E8, we thought to ourselves, “What volunteers want is not high technology, but usability and peace of mind.” So from technology to design, every aspect is focused on the pain points mentioned earlier:

1. There is no lag when two people speak together, and the cooperation between volunteers and experts is extremely smooth

E8 supports “main and secondary dual speaking”. Volunteers and experts each bring a transmitter. There is no need to compete for the microphone. They can fill in the microphone whenever they want. The sound transmission is not delayed at all, and the audience cannot detect the “switching sensation” at all.

Xiao Wang from the Henan Provincial Museum is now talking about the terracotta figurines. Cultural relics experts can chimed in at any time: “The cobalt material of this terracotta figurine came from Persia. Back then, it took half a year to reach Chang ‘an along the Silk Road.” The two of them acted in harmony, and the audience not only understood history but also knew the craftsmanship. At the Huawei Industrial Exhibition, volunteers explained the production line, and technicians simultaneously added that “energy-saving parameters can be customized during mass production”. There was no need to wait or be interrupted, and the explanation efficiency was 30% higher than before. The technician said, “Previously, we were afraid of interrupting the volunteers. Now, we can make up for it whenever we want. The audience can understand clearly and we can rest easy.”

2. Just press it and it will turn on. You can use it without learning

The receiver of E8 is particularly simple: Press the SET key to turn it on, and it will automatically search for signals from nearby transmitters. It only takes 3 seconds to connect, eliminating the need for manual channel adjustment. On the LCD screen of the transmitter, the channel, battery level and volume can be clearly seen. Volunteers can know the status of the equipment at a glance without having to refer to the manual.

Xiao Chen from Taihu Lake in Suzhou used the E8 for the first time. He moved from the pier to the exhibition area on the island in the middle of the lake, turned off the receiver and turned it on again, and directly connected it to the new transmitter without wasting a second. The Chinese volunteers at the Louvre led an international tour group. Foreign tourists received the receivers and pressed the power button to make a sound. No one asked, “How do you change the channel?” Xiao Chen said, “In the past, it took half a day to adjust the equipment when changing exhibition areas. Now, we can start using it right after turning it on. The time saved allows us to talk about two more scenic spots.”

3. It has a long battery life and is very easy to use, and it’s super convenient to manage

The receiver of E8 can last for 8 to 10 hours on a single charge, providing service from 9 a.m. to 6 p.m. The battery power is more than sufficient. The 36-digit or 48-digit contact charging case that comes with it is more convenient. Just place the receiver in the slot and it will start charging without the need for wires. It also comes with ultraviolet disinfection. Disinfect it after each service day, and you can use it with peace of mind the next day.

The volunteer team at a certain exhibition consists of 50 people. They use a 50-seat storage box to carry the equipment. During the moving process, the EVA shock-absorbing cotton inside can protect the machines and prevent them from being knocked. It used to take one hour every day to charge and tidy up the equipment, but now it only takes ten minutes. The person in charge said, “There has never been a situation where the equipment ran out of power and service was cut off again. The time saved can be used to train more volunteers.”

III. From domestic to global, E8 helps volunteers spread their stories far and wide

E8 is not only useful in China but also can solve the problems of volunteers abroad – whether it’s museums in Europe, scenic spots in Southeast Asia, or exhibitions in the Americas, the core requirements are the same: clear hearing, easy cooperation, and easy operation.

After the volunteers at the Louvre in France used E8, the feedback from the international tour group improved significantly: A Spanish tourist said, “Finally, I can clearly understand the details of the Mona Lisa’s creation and no longer need to rely on translation.” Italian tourists feel that “it’s so comfortable to be able to wander freely without following the tour guides in crowds and to hear the explanations clearly.”

Volunteers at scenic spots in Phuket, Thailand, used to use megaphones. When the sea breeze blew, there was no sound and they could only talk close to tourists. Now with E8, no matter how strong the sea breeze is, tourists can clearly hear the “No-mooring area of coral reefs” within 200 meters. When Chinese tourists switch to the Chinese channel, they can still listen to “How fishermen on the island cooperate with ospreys to catch fish”, without having to rely on tour guides to demonstrate.

At the electronics show in Las Vegas, USA, volunteers led buyers to visit multiple booths. Previously, changing booths required adjusting channels, which wasted time. Now, with E8, when changing booths, the receiver automatically connects to the new channel. Volunteers and technicians explain in coordination. Chinese buyers said, “This time, the explanations went very smoothly. All the parameters that needed to be understood were clear. There was no need to ask repeatedly. The efficiency was much higher.”

IV. Yingmi Technology: Helping volunteers convey every word accurately

Yingmi Technology’s development of E8 is not about selling a “device that can make sounds”, but rather about serving as a “caring helper” for volunteers – enabling them to focus on saying what they should say and spreading the culture they should convey without having to shout, worry or panic.

We also promise: a 90-second rapid response to inquiries before sale, and free sample delivery for volunteers to try first. If necessary during the sales process, we can visit your place to inspect the service scenarios. Urgent orders can be dispatched on the same day. After-sales service is more reassuring. Sf Express offers free shipping and repair, and they can also provide spare equipment. If it breaks down, it comes with a lifetime warranty – we just don’t want equipment problems to delay volunteer services.

Up to now, E8 has served over 4,000 clients worldwide, from Xiamen’s Gulangyu Island and Henan Museum, to exhibitions of Huawei and Adidas, and even to the Louvre in France and Phuket in Thailand. Behind all these events, there are the smooth figures of volunteers providing services.

We know that the voices of volunteers are filled with culture and enthusiasm, and deserve to be clearly heard by every listener. In the future, we will add more practical functions to E8: for instance, adding more minority languages to enable volunteers in more regions to use it. Optimize cloud management to facilitate the advance recording of explanation scripts; Make the equipment lighter and have a longer battery life to further reduce the burden on volunteers.

Whether in domestic scenic spots or international exhibitions, Yingmi E8 wants to accompany the volunteers and smoothly convey every story and every detail to the hearts of the audience – making volunteer services easier and cultural exchanges more borderless.
