Anhui University, located in Hefei, not only has a knack for academic research and talent cultivation, but also frequently receives visitors from all over the country – including government VIPs for educational visits, overseas scholars for academic exchanges, and student groups for study Tours. The university’s history collection on campus houses stories since its establishment. The landscape of Qingyuan Campus carries the flavor of Jianghuai culture, and the research achievements in the laboratories are a testament to the university’s strength as a “Double First-Class” institution. But before, these matters worth discussing well were always held back by the troubles during the reception. Fortunately, in 2021, Anhui University purchased Yingmi’s audio guide for the first time. It was both convenient and reliable to use. Later on, when there was a need for reception, the purchasing team immediately thought of Yingmi. This time, based on the actual situation of the campus, Yingmi recommended the K8 team guide system. She also sent the equipment to the school for testing first. Only after confirming that there were no problems would they cooperate. After all, for Yingmi, it doesn’t matter whether she says the equipment is good or not. What really matters is that the customer is satisfied with it.
I. Reception Difficulties of Anhui University
As a key university, Anhui University has much more complex reception demands than ordinary schools: the team size is large, the scene range is wide, and the visitor demands are diverse. However, traditional interpretation equipment simply cannot keep up, and each reception leaves the responsible teachers feeling frustrated.
1. When there are many people, it’s “hard to hear clearly” : The core information doesn’t reach the ears
The number of teams that Anhui University can receive at one time can be as many as over 60, such as the parents’ group of freshmen and the student study tour group. The university history museum is a must-visit place. Inside, there are historical documents of the university and photos of academicians. The guide has to explain in detail that “the university has 13 postdoctoral research stations” and “how the ‘Double First-Class’ disciplines were built”. However, when the footsteps and conversations in the crowd get mixed up, people in the back row can’t even hear the “key time points” clearly.
Mr. Wang, who was in charge of the reception, remembers it very clearly: “Once when I led a student group to visit the academician wall, I repeatedly emphasized, ‘This academician is engaged in quantum communication research,’ but still some students came over and asked, ‘Teacher, is he in biology?'” “;” When I reached the outdoor Wendian Pavilion, the leaves rustled in the wind. I had to shout the explanatory notes at the top of my voice. By the end of the day, my voice was so hoarse that I couldn’t even swallow water. Visitors also complained that they didn’t understand.
If overseas scholars are invited to the laboratory, the trouble will be even greater. The scholars have to listen to the “parameters of scientific research equipment” and the “details of experimental procedures”, but the noise from the traditional guide covers the key data. The scholars can only stop and approach the guide to ask questions. The originally half-hour visit is forced to be extended to nearly an hour, and the rest of the itinerary is completely disrupted.
2. Signal “cut off” when changing scenes: Switching between indoor and outdoor is too awkward
The reception route of Anhui University often shifts from “closed” to “open” : first, visit the university’s history museum (a small space) to view the school’s history, then go to the laboratory (a semi-closed space) to observe scientific research, followed by strolling around the campus along the scenic avenue (an open area), and finally, they might even go to the gymnasium (a large space). Traditional interpretation equipment can still be used indoors, but it frequently malfunctions when outdoors.
Teacher Wang once shared a particularly embarrassing experience: “One time, when I was leading government guests from the school history museum to the school motto stone, the audio guide suddenly went silent. I had no choice but to temporarily use a loudspeaker to speak. The sound was shrill and harsh, and it even attracted the attention of passing students. It felt extremely unprofessional.” ” Even in a large space like a gymnasium, signal reflection causes noise to superimpose. Even simple information like “How large is the floor area of the gymnasium?” sounds blurry.
3. Equipment management is “too laborious” : Channel adjustment and charging consume a lot of manpower
Anhui University often “receives guests on multiple lines” : at the same time, there are VIP groups in the university history museum, academic groups in the laboratories, and student groups in the scenic area. However, the traditional interpretation equipment only has a few channels. Before each reception, the staff have to spend one hour manually adjusting the channels for each receiver, fearing that different teams might “crosstalk”. During the reception, someone accidentally touched the wrong button and had to adjust it again. After the reception, each device needs to be plugged in one by one for charging. I have to be busy with 50 devices for most of the day, and I’m always worried that some might miss charging, which could affect their use the next day.
When the purchasing team bought Yingmi equipment for the first time, they valued “easy management” : “Before, when we used other brands, we had to assign two people to manage the equipment each time we received guests. It was tiring and prone to errors.” Yingmi’s equipment saved us a lot of trouble at that time, so when we had a need this time, our first reaction was to turn to them.
II. Yingmi K8: “Prescribe the right medicine” for difficult problems to make reception easier
After learning about the troubles of Anhui University, Yingmi did not directly promote the ready-made equipment. Instead, she sent the technical team to the campus for several days of on-site observation: they tested the acoustic environment in the school history museum, tested the signal on the scenic avenue, and also talked with the reception teachers about the needs of different teams. Finally, they decided on the solution of the K8 team’s explanation system – each function precisely addressed the pain points of the school.
1. Automatic binding + multiple channels: No need to change channels, and no cross-linking even among multiple teams
The most reassuring feature of K8 for the reception team is the “automatic channel binding”. Previously, channel adjustment had to be done manually, and it would take half a day to handle 50 devices. Now, as long as the transmitter is unlocked and turned on, the receiver will automatically search for the signal and bind it as soon as it approaches, and it can be done in just 3 seconds. Visitors can use the equipment as soon as they pick it up, and the staff no longer need to spend time debugging it in advance.
Moreover, K8 supports 65 independent channels, so there’s no need to worry about crosstalk even when multiple teams are hosting simultaneously. For instance, the VIP group in the university history museum uses Channel 10, the academic group in the laboratory uses Channel 25, and the student group in the scenic area uses Channel 40. Everyone talks their own way and their voices do not interfere with each other. Teacher Wang said, “Last time, we received three teams in one day. There wasn’t a single crosstalk. The reception efficiency has increased by 40% compared to before, and we don’t have to be in a rush anymore.”
The LCD screen on the transmitter is also very practical. The battery level, current channel, microphone volume and the progress of the pre-stored audio can all be clearly seen. During one reception, the transmitter’s battery level dropped to only 20%. As soon as the screen prompted, the guide promptly replaced it with a backup device without missing any steps.
2. Anti-interference + remote transmission: Clear both indoors and outdoors, with no signal interruption
To address the issue of “signal disconnection when changing scenes”, K8 has been optimized both in technology and hardware. It uses the U-band high frequency of 790MHz-870MHz. This frequency band is far from the interference of mobile phones and WiFi, just like opening a “special path” for the audio guide – in the school history museum, the sound can penetrate the crowd and reach the back row. When reaching the scenic avenue, the signal can cover a distance of 200 meters. The guide walks at the front of the line, and the people at the end of the line can also hear clearly.
Even more impressive is the “Digital Anti-interference technology” of K8, which can automatically filter out environmental noise. The footsteps in the university history museum, the wind in the scenic area, and the sounds of equipment operation in the laboratory will all be intelligently filtered out, leaving only the voices of the tour guides and the pre-stored audio. After visiting the laboratory, overseas scholar Dr. Smith said, “When I went to other universities before, the audio guide was full of noise and I couldn’t hear the key data clearly.” This time with the K8, even though the centrifuge beside it was rotating, I could still clearly hear “the detection accuracy of the equipment is 0.001mm.” It’s so professional.
The technical team also conducted a special test on campus: from the school history museum to the Wendian Pavilion and then to the gymnasium, the signal of K8 was never interrupted throughout the entire process, and there was no noise either. Teacher Wang said, “Now when taking VIPs on a tour, we no longer have to worry about ‘silence halfway’. The professionalism of our reception has improved, and we are more confident.”
3. Lightweight and comfortable + long battery life: You won’t feel uncomfortable wearing it for a whole day and don’t need to charge it frequently
The reception at Anhui University usually lasts for 6 to 8 hours, from morning till afternoon. The “comfort” and “battery life” of the equipment are particularly important. K8 has done a great job in these two aspects:
The receiver is designed as a “non-in-ear ear hook”, weighing only 22 grams, almost as light as a leaf. Visitors can wear it all day without feeling any ear pain. In the past, when using in-ear devices, there were always people complaining that they felt uncomfortable after wearing them for a long time. But after switching to the K8, such complaints have almost disappeared. A child from a student group said, “Before, I wanted to take off the audio guide after wearing it for half an hour. This time, I wore the K8 for three hours and didn’t feel uncomfortable at all. I could also focus on listening to the school history stories.”
The battery life is also sufficient. The transmitter is equipped with a 1500mAh lithium battery, which can be used continuously for 10 hours after a single charge. The receiver is equipped with a 360mAh battery and can last for 10 hours, which is more than enough for a full day of reception. Even if the device is used from 9 a.m. to 5 p.m., it still has 20% of its battery left, so there’s no need to look for a place to charge it in the middle.
Considering the hygiene issues of university receptions, the ear hangers of K8 are made of food-grade silicone and can be removed for disinfection. The logistics teacher said, “After each reception, we take off the ear loops and wipe them with alcohol. This way, visitors can use them with peace of mind next time.”
4. Pre-stored audio + multiple languages: Different visitors will be satisfied
The demands of visitors to Anhui University are far from diverse: government VIPs want to know about the “achievements of the school”, students enjoy listening to “interesting stories about the school’s history”, and overseas scholars need “professional terms + foreign language explanations”. The “Pre-stored audio” and “Multilingual support” features of K8 precisely address this issue.
The tour guide can record the school’s history, discipline construction and scientific research achievements into the transmitter in advance, with a maximum of 9,999 segments stored. When receiving student groups, play “Little Stories of Academicians’ Studies”. When receiving distinguished guests, core data such as the number of postdoctoral research stations and research funds should be broadcast. When receiving overseas scholars, provide explanations in English and Japanese, and there is no need to find additional translators.
Teacher Zhang, who is in charge of academic exchanges, said, “In the past, when receiving overseas scholars, we had to bring a translator along, which was not only inconvenient but also prone to missing details.” Now, with the multilingual audio of K8, scholars can understand it clearly by wearing headphones themselves. They can also pause to ask questions at any time, and the communication efficiency has been much higher.
Iii. Implementation Effect: The reception at Anhui University has changed
After K8 was put into use at Anhui University, it not only solved the old problems but also transformed the reception work from “fulfilling tasks” into “a window for transmitting culture and academia”, and the changes were truly visible.
1.The reception efficiency has improved and the labor cost has decreased
In the past, when receiving a team of 50 people, two people needed to adjust the equipment and one person had to give explanations. Now, one person can prepare the equipment and manage a team of 50 people, reducing labor costs by 40%. Moreover, the multi-channel support enables the school to receive an additional two groups of visitors each day, increasing the daily reception volume from three groups to five groups and improving efficiency by 50%. Staff members no longer have to work overtime all the time.
Teacher Wang said, “There are a lot of parents’ groups during the back-to-school season. Previously, we had to wait until a week later, but now we can arrange it on the same day. Parents are satisfied and we feel relaxed too.”
2. Visitor satisfaction has increased and complaints have disappeared
The school conducted a survey. After using K8, the satisfaction rate for “clear sound” rose from 65% to 98%, for “comfortable equipment” from 70% to 96%, and for “professional reception” from 75% to 95%. The complaints that used to be frequent, such as “I can’t hear clearly”, “my ears hurt” and “the equipment is broken”, have basically disappeared now.
Overseas scholar Dr. Smith commented: “The sound quality and stability of the K8 exceeded expectations, allowing me to focus on understanding the academic achievements of Anhui University. This professional equipment shows the school’s respect for visitors.” ” Ms. Li, a parent of a new student, also said, “When I went to other universities before, I was always afraid of missing key information. This time with K8, even standing at the end of the queue, I can clearly hear the scholarship policies and dormitory conditions. I feel very reassured.”
3. Culture and academia have spread more deeply
What makes the school happiest is that K8 has made the transmission of the school’s history and academic spirit more in-depth. In the past, visitors to the school history museum would only have a cursory look, remembering a few exhibits and then calling it a day. Now, listening to the pre-stored stories about the school’s history and interviews with academicians, visitors can understand “why the school motto is’ Utmost Sincerity and Perseverance, Extensive Learning and Diligent Practice ‘”, and can feel” the influence of Jianghuai culture on academic research “.
After the visit, a student group voluntarily asked the teacher, “The research stories in the school’s history.” After listening to the multilingual explanations, overseas scholars also put forward the idea of collaborative research. Professor Liu, who is in charge of the school’s history, said, “K8 is not merely a tool for spreading voices; it is also a cultural bridge that enables more people to understand the spirit of our school. This is the true meaning of reception.”
Conclusion: Let the “voice” of colleges and universities reach further
In the university history museum of Anhui University, the “Academic Achievements Wall” records every step of the “Double First-Class” construction. In front of the school motto stone at Qingyuan Campus, every day, students silently recite “Utmost sincerity and firmness, extensive learning and diligent practice”. These contents that embody the spirit and culture of colleges and universities need clear voices to interpret and reliable equipment to convey.
The Yingmi K8 team interpreter is such a “transmitter” – it solves the troubles in reception and enables the academic stories and cultural heritage of Anhui University to be clearly heard and remembered by every visitor. For overseas educational institutions, Yingmi offers not merely a set of equipment, but a solution that “ensures the effective dissemination of culture and academia”.
In the future, Yingmi will continue to refine its technology and provide excellent services, ensuring that the “good voices” of more universities around the world can be clearly heard in every corner of the globe.
