When organizing a small group tour with about 20 people overseas, the most worrying thing is that the equipment might malfunction. They intended to provide a high-quality guided tour, but the traditional audio guides kept interfering with each other. The tour guide would be saying "The history of gladiators at the Colosseum in Rome", while the tourists' ears would be filled with the "discounts at the souvenir store" from the neighboring group. Sometimes the battery life wouldn't last for the entire day, and they would have to find a place to charge the 20 devices at noon, which would delay the visit to the attractions. What's more annoying is the language switching. European tourists might want to switch to French, but the tour guide would have to adjust the equipment one by one, and the 20 people would have to wait for half an hour. These things may seem insignificant, but they can completely ruin a good small group experience. Yingmi has developed this 1-to-20 wireless guide device specifically to address these problems faced by overseas small group tours. It is resistant to interference, has long battery life, is easy to manage, and offers convenient multi-language switching. It is favored by tours for small groups such as those organized by the Huawei small group reception, Gulangyu free tour small group, and the British Museum study tour small group.
    Yingmi has been in the guided tour equipment business for 15 years. This 1-to-20 guide device is not a modification of a large group device for a smaller one; it is specifically designed for small group scenarios. For teams of 20 or fewer people, it can be turned on and used immediately, without complex settings or worries about equipment waste. More than 4,000 overseas users recognize it. Whether it's government small group receptions, corporate client visits, or scenic area's high-quality small group tours, people are willing to use it for a long time because Yingmi understands the difficulties of small groups: there are not many people, but the equipment cannot be poor; it must be precisely adapted.

I. In overseas 1:20 small groups, these 4 issues are the most troublesome

A small group of around 20 people, although not many in number, can easily expose the problems of traditional audio guides. Overseas tour guides and scenic area operators often suffer from these issues:

1. Interference keeps occurring, making it impossible for the 20 people to hear the proper content clearly

In popular tourist attractions and exhibition halls, traditional audio guides have few channels and poor anti-interference capabilities. It's very likely for the 20-person team to pick up the signal from others. When Martin, an overseas tour guide, led a 20-person European tour group to visit the Roman Colosseum, he encountered a frustrating incident: "Just as I was explaining 'how the armor of the gladiators was made', the equipment suddenly picked up the signal from another group 'there are handmade necklaces for sale ahead', and a French tourist directly took out his phone to record. As a result, what was recorded was all the voices of others, and he immediately frowned." What's worse, even after adjusting the channel, it still didn't work. "Among the 20 devices, 3 were still interfering. Finally, I had to ask these 3 tourists to stand in the front row. The originally good small group ended up being like a crowded bus."

2. The battery life doesn't last for the whole day, and charging midway ruins the itinerary

The small group tours usually last from morning to evening (from 9 a.m. to 5 p.m.). Traditional audio guides have a battery life of only 4 to 5 hours. At noon, they must stop to find a place to charge. Ms. Chen from the Dubai scenic area said: "Once a 20-person small group went to the desert to watch the sunset, at 11 a.m., 5 devices ran out of power. They could only let the tourists take turns using the remaining 15 devices. Those without devices had to listen behind. An elderly person directly said, 'It's better to just look at the signs ourselves,' which was very embarrassing." What's more troublesome is that even after adjusting the channel, it still didn't work. "Among the 20 devices, 3 were still interfering. Finally, I had to let these 3 tourists stand in the front row. The originally good small group ended up being like a crowded bus."

3. Switching between multiple languages is troublesome, and the 20 people have to wait for a long time

Overseas small groups are often "mixed language groups" - 10 speaking English, 5 speaking French, and 5 speaking Japanese. Switching languages with traditional equipment requires manual adjustment and a restart. The Middle Eastern tourist Karim, when participating in a 20-person study tour group, encountered this problem: "I wanted to switch the device to Arabic. I asked the tour guide to adjust it. He held my receiver and pressed it for a long time, and then had to restart it. During this time, other tourists were standing in the sun. A student directly sat on the ground to play with his phone. In the end, I had to give up. The whole group couldn't understand many details." What's worse is that the channel would be interrupted after restarting. "After restarting, I had to connect each of the 20 devices one by one. Half an hour passed, and we only managed to see 2 out of 3 exhibition halls."

4. Managing the equipment is exhausting, and the 20 devices have to work until midnight

After the small group tour ends, collecting the equipment, charging, and disinfecting can wear people out. Traditional equipment needs to be plugged in one by one for charging. With 20 devices scattered on the ground, Ms. Wang from Xiamen Gulangyu said: "Previously, we used other brands. It took 2 hours to charge 20 devices, and we also had to use alcohol cotton pads to wipe each ear hook. From 10 p.m. to 1 a.m., we had to get up early to pick up the group. We were also worried about losing the equipment." "Once we finished collecting, we lost 1 device. The entire group searched for it on the benches and bathrooms in the scenic area for 1 hour. Finally, we found it in the gap of the Colosseum steps and were both anxious and tired."

II. Yingmi 20 Lectern: 5 Real Advantages, Solving Problems for Small Groups

Yingmi doesn't have those fancy features. It focuses solely on designing solutions for the problems faced by small groups of 20 people. Each advantage can directly solve the problem:

1. 200 encrypted channels, ensuring clear and non-interfering listening for 20 people

To address the issue of interference, Yingmi used two methods: multiple channels + encryption. Even if several small groups gather together, each group can listen to their own content:
200 channels are sufficient: from CH-01 to CH-200, 10 groups of 20 people can use them simultaneously, with wide channel intervals and no interference. Martin now leads a group to visit the Colosseum, "We use CH-32, the neighboring group uses CH-58. Even if they are close, no one else's commentary can be heard. A German tourist said, 'This time, I can finally hear every detail clearly'";
Channels with exclusive passwords: When binding the channel, it will be associated with an exclusive password. Even if other teams have close channels, they won't be able to interfere. Huawei received a group of 20 German suppliers in Dubai. The workshop machinery noise was very loud, but the equipment didn't experience any interference. The supplier said, "The 0.01 millimeter error in chip detection was clearly heard, which is much better than the equipment at the previous exhibition";
Can filter out environmental noise: The SOC noise reduction technology in the equipment works well. The human voices in the scenic area and the footsteps in the exhibition hall can be filtered out by 90%. Even when the tour guide speaks normally, the last person in the group of 20 can still hear clearly.

2. Long battery life, sufficient for the entire day without charging

The battery life of this device is designed based on the entire day's itinerary of a small group. There is no need to look for a charging place during the journey:
Transmitter lasts 15 hours: The tour guide uses it from 9 a.m. to 6 p.m., and there are still two battery bars left, so there is no need to carry a power bank around;
Receiver lasts 8 hours: Tourists can use it throughout the day. Even if they occasionally forget to turn off the device, they can still last until the end of the trip. Sister Chen used it in the desert scenic area, "The 20-person small group from sunrise to sunset had no device without power. Once they added a 'Starlight Tour Guide' service, the equipment also held up, and the tourists' satisfaction increased significantly";
Can withstand high and low temperatures: The battery has undergone tests from -20°C to 45°C. Even in Dubai at 45°C, the device still has a battery life of 8 hours; in Iceland at -15°C in the glacier, it doesn't suddenly lose power either. "The 20-person research group stayed in the glacier for 8 hours, and the equipment still worked normally";

3. Can switch between multiple languages by itself, no need to wait for the tour guide

Switching between multiple languages for a small group doesn't require looking for the tour guide. Tourists can operate it themselves:
8 commonly used languages are pre-stored: English, French, German, Japanese, Arabic. These languages are all pre-installed in the device. Once the channel is set, it will automatically synchronize to the 20 receivers without having to pass them one by one;
Press one button to change languages: Tourists press the "LANG" button, and there are small icons on the screen, EN is English, FR is French, AR is Arabic. No need to restart the device, it takes only 2 seconds. Karim last time led a research group, "He changed to Arabic by himself and repeatedly listened to the details of glacier formation. It was much clearer than listening in English. There was no need to bother the tour guide";
Customizable for minority languages: 3 days in advance, tell Yingmi about Swedish and Portuguese, and it will be done for you without any additional charges. A 20-person research group from Sweden used it and "The students directly chose Swedish for the tour guide, which was 10,000 yuan cheaper than hiring a translator";

4. Easy to manage the equipment, 1 hour to handle 20 devices

There is no need to stay up late to collect the equipment, charge it, and disinfect it. Yingmi has a dedicated tool:
36-pin contact charging box: 20 devices don't need to be plugged in. Just put them in the box and they can be charged. It's fully charged in 3 hours, twice as fast as before. Sister Wang said, "Previously, it took 2 hours to charge 20 devices. Now it takes only 1 hour, no need to keep an eye on the plug-in, and can leave work earlier to accompany the children";
Automatic disinfection without wiping: Place the device in the charging box, and it will automatically undergo ultraviolet disinfection for 30 minutes, killing 99% of bacteria. There's no need to wipe it one by one with alcohol swabs. "Middle Eastern tourists have high hygiene requirements. After using Yingmi, no one ever asks 'Has this device been used by others before?'"
Backstage can show where the devices are: Log in to the Yingmi cloud backend, and you can see the status of 20 devices - whether they are returned or not, whether they need repair. "No devices have been lost. The annoying incidents of looking for devices before no longer occur."

5. Lightweight and durable, small groups won't get tired carrying it

Overseas small groups often go outdoors, so the equipment needs to be lightweight and durable. Yingmi has made great efforts in this aspect:
Light as if not wearing it at all: The receiver weighs only 16 grams and is ear-loop style. Even for the elderly and children among 20 people, wearing it for 2 hours doesn't hurt their ears. "There was a 6-year-old child in the study tour group. He wore it all afternoon without taking it off, saying 'It's like wearing a small earphone, it doesn't hurt.'"
Waterproof and dustproof, not afraid of being made: The device is IP65 waterproof and dustproof. In the desert, if it gets sand, just wipe it off and it can still be used; at the seaside, if it gets seawater, just dry it and it will still work. "Once a small group in Maldives dropped the device into the sea. After retrieving it and cleaning it, it could still be used normally."
Global usability: After obtaining EU CE and RoHS certifications, it has no problems entering customs in 40+ countries; it supports a wide voltage range of 100-240V. When going to Europe, America, or the Middle East, just plug it in to charge, and no additional converter is needed.

III. Overseas Test: How Good Is Yingmi1 for 20?

How good is this device? It's not just words; it's the real-life experiences of overseas small groups that have been tested and verified. Each experience is truly tangible:

1. Huawei Dubai Small Group Reception: Anti-interference and Professional

Huawei received a small group of 20 German suppliers and visited the chip workshop in Dubai. They used the Yingmi E8:
The noise from the workshop machines was extremely loud. The equipment filtered out 90% of the noise, and even when the supplier was 10 meters away, they could clearly hear "The 3 steps of chip inspection";
200 encrypted channels avoided the complex signals of the workshop, and there was no audio interference. A German engineer even said, "It's clearer than the equipment used at the Frankfurt exhibition last time";
From 9 a.m. to 6 p.m., the device still had 25% battery power, and there was no need to look for a charging place during the journey, and the trip went smoothly.

2. Gulangyu Free Tour Small Group: Self-service is Convenient

A 20-person free tour small group (10 English, 5 Japanese, 5 Korean) used the Yingmi i7:
Tourists could scan the code on the rental cabinet to get the equipment, select the "1-on-20 small group mode", and the device would automatically connect to the channel upon startup, without waiting for the tour guide;
Japanese tourists could switch to Japanese by pressing a button, and listen to "The Piano Story of Zhushizhuang Garden"; Korean tourists could switch to Korean to listen to "The History of Zheng Chenggong at Dayou Rock", each enjoying their own activities, without being urged by anyone;
Sister Wang said, "Previously, the rental rate for small groups was only 40%, but after changing to Yingmi, it rose to 75%. An American tourist even said, 'There's no need to squeeze with large groups, and I can enjoy a comfortable tour experience myself'".

3. British Museum Study Tour Small Group: Longevity and Convenience

A 20-person Swedish study tour small group, viewing the "Special Exhibition of Chinese Fashions from the Song Dynasty", used the Yingmi R8:
Yingmi customized the Swedish language interpretation in advance, and once the channel was connected, it would automatically synchronize, and students could switch languages themselves, without the tour guide adjusting one by one;
From 10 a.m. to 6 p.m., the device still had 30% battery power, and there was no power outage;
When returning the equipment, it was placed in the charging box, and it was fully charged and disinfected in 1 hour. The guide said, "Previously, I had to stay up late to set up the equipment, but now it's done in 1 hour, allowing me to prepare the next day's explanations earlier".

IV. Conclusion: Small Group Tours Require "Convenience" Not "Showy Features"

When leading a small group of 20 people, it is originally intended to offer a high-quality itinerary. The equipment cannot be a hindrance. The Yingmi 1-on-20 wireless interpreter does not boast "Supporting 100 people" but focuses on the needs of small groups - no audio interference, sufficient battery life, self-language switching, and convenient management, allowing the tour guide to no longer struggle with the equipment, and allowing tourists to focus on enjoying the scenery and stories.
