Last year, when Dutch Sinology scholar Yang Ke first visited the Suzhou Museum, he was at a loss when facing the audio guide devices at the rental counter - the earphones in the transparent cabinet had faint fingerprints, and the device casing was also covered with fine dust. Although the staff said "it has been wiped", he still hesitated for a long time and finally preferred to browse the exhibition with the paper guide book, missing out on many details of the cultural relics. In fact, many overseas tourists who rent audio guides at museums also have similar hygiene concerns: will the equipment be disinfected? Will the earphones, which have been used by many people, have bacteria? Can the disinfection process be reassuring?
    As a brand that has focused on voice-guided tours for 15 years under Hefei Huima Information Technology Co., Ltd., Yingmi Museum Audio Guide has long regarded "disinfection" as a core aspect. It is not just a simple "wipe", but a standardized operation covering the entire process from "device recycling - disinfection - storage - rental". From the dense exhibition areas of the Suzhou Museum to the special exhibitions of the Chinese National Museum, from the cultural relic corridors of the British Museum to the interactive exhibition halls of the Dubai Natural History Museum, Yingmi uses visible disinfection details to ensure that overseas tourists no longer worry about hygiene issues. This is also the key to its long-term service to many top museums around the world - after all, for cultural experiences, "safety" is the prerequisite for having a good visit.

I. Here is the answer: The Yingmi Museum Guide Device is disinfected every time it is used

Many overseas users are concerned that "the disinfection of the museum guide device is just a formality", but Yingmi's disinfection process is never "formalism"; it has clear standards and traceable operations. The core principle is "any place touched by the user must be thoroughly disinfected":
Whether it is the rented i7 ear pendant type, C7S touch type, or the team's E8 guide device, as long as it is returned to the Yingmi self-service rental counter or human counter, the first step is disinfection - not simply wiping with alcohol cotton pads, but through "physical disinfection + chemical disinfection" dual treatment to ensure the elimination of over 99% of common bacteria (such as Escherichia coli, Staphylococcus aureus). After cooperating with Suzhou Museum, after the museum closes every day, the disinfection records of that day will be publicly displayed. Japanese tourist Sato saw the notice "The C7S guide device has been disinfected 32 times, and the earphone has been exposed to ultraviolet light for 30 minutes" and felt relieved to rent the equipment: "Before renting the guide device at other museums, the staff only said 'disinfected', without specific records. Yingmi is so transparent, it makes people feel at ease."
More importantly, Yingmi's disinfection covers all the user contact points of the equipment: earphone ear cushions, device buttons, screens, charging interfaces, even the point-touch labels of C7S (which tourists frequently touch) will be wiped with medical alcohol regularly. Later, when Yang Ke went to Suzhou Museum again, the i7 guide device he rented not only had a clean shell, but also had a faint smell of disinfection after drying on the earphone, "Wearing it on the ear did not cause any discomfort, it was even more reassuring than my own earphone."

II. Yingmi has addressed all the pain points that overseas users are concerned about regarding disinfection

Overseas users often have concerns about the disinfection of the museum audio guides, mainly focusing on "inadequate disinfection", "accumulation of dirt inside the equipment", and "difficulty in ensuring the hygiene of the earphones". However, Yingmi's design and process have specifically addressed these pain points:

1. Pain point one: Incomplete disinfection, unsure if it was truly disinfected

The disinfection process of traditional museum audio guides is often "behind closed doors", with users unable to see the process and only hearing the staff say "disinfected". They have no idea what's going on. Yingmi's solution is "visualized process + recordable and verifiable":
Self-service rental and sales cabinet automatic disinfection: After users return the audio guide, the rental and sales cabinet will automatically close the disinfection compartment and start ultraviolet light irradiation for 30 minutes. During the disinfection process, the screen will display "Disinfection in progress, please do not open". Overseas users can directly see the disinfection progress; after disinfection is complete, the background will record "disinfection time, disinfection method, operator", and museum staff and users can scan the code to view it. Norwegian tourist Erik, after scanning in Suzhou Museum, saw that the C7S audio guide he rented was "returned at 10:23, ultraviolet disinfection from 10:25 to 10:55, alcohol wiping of buttons", "Every step has a record, which is much more reliable than 'oral guarantee'".
Manual counter disinfection notice: In museums without self-service rental and sales cabinets, Yingmi will provide standardized disinfection toolkits (including ultraviolet disinfection lamps, medical alcohol cotton pads, and disinfection record forms). Staff will register on the form each time they disinfect a device, and the form will be placed in a prominent position on the counter, allowing users to check at any time. At the manual counter of the National Ethnic Museum, many overseas tourists often voluntarily check the form, "Seeing that the device I want to rent has just been disinfected, I feel much more at ease".

2. Pain point two: Seams of the equipment accumulate dirt and the disinfection is not thorough

After using the museum audio guide for a long time, the keyhole of the buttons and the earphone interface are prone to accumulate dust and bacteria. Traditional disinfection only cleans the surface, and the dirt in the seams cannot be completely removed. Yingmi considered "easy disinfection" during the equipment design stage:
Seamless design of the shell: The shells of i7 and C7S adopt an integrated injection molding process, with no extra gaps, making dust and sweat less likely to accumulate. With an alcohol cotton pad, it can cover all surfaces during disinfection; unlike some audio guides with obvious keyhole gaps, the dirt inside can still be seen after cleaning, Yang Ke said, "The equipment of Yingmi feels very smooth, there are no places to accumulate dust, and the disinfection must be more thorough."
Earphone detachable + anti-fouling material: The earphone covers of Yingmi audio guides (especially the non-in-the-ear ear hooks of E8 and the earplugs of C7S) are made of medical-grade cleanable silicone, not only skin-friendly but also can be directly wiped with alcohol, unlike sponge earphone covers that absorb alcohol and accumulate bacteria; some earphone covers support detachment, allowing museums to replace new earphone covers regularly, further reducing the hygiene risk. The staff of the Dubai Natural History Museum said, "Before using the audio guide with sponge earphone covers, the smell would appear after one week. After changing to Yingmi's silicone earphone covers, disinfection is very convenient every day, and the earphone covers haven't been replaced for half a year without any smell."

3. Pain point three: Concerns about cross-infection due to shared earphones

Earphones are the hygiene concern that overseas users are most concerned about - direct contact with the ear, if the disinfection is not thorough, it is easy to cause cross-infection. Yingmi has made dual guarantees for the disinfection and design of earphones:
Ultraviolet + alcohol dual disinfection: After returning the earphone, it is first placed in an ultraviolet disinfection compartment for 20 minutes to kill surface bacteria; then it is taken out and wiped with medical alcohol cotton pads on the inner side of the earphone cover (the part in direct contact with the skin), ensuring no omissions. The statistics of Suzhou Museum show that the earphones disinfected with dual disinfection have a bacterial detection rate of almost zero; Multiple sizes of earplugs + individual packaging: The earplugs for C7S and i7 headphones come in three sizes - large, medium, and small. Users can choose the size that suits their ear canal. This reduces the friction between the earplugs and the ear canal, and also lowers the risk of bacterial residue. For users who are particularly sensitive to hygiene (such as those with allergies, the elderly, and children), Yingmi also provides disposable earplugs in individual sealed packaging. These can be used immediately after opening and can be taken away after use. When Swedish study tour guide Anna took primary school students to visit the museum, she would always apply disposable earplugs for the children: "Parents are very reassured. There's no need to worry about other children's used earplugs having bacteria."

III. Disinfection Details of Yingmi Museum Exhibition Lecturer: From Equipment to Process, Everything is Secure

The disinfection of Yingmi is not a "single step", but a systematic project that runs through the entire process from "equipment design - user use - recycling disinfection - re-rental": Every detail is considered for the hygiene and safety of overseas users:

1. Equipment Design: Reduce disinfection difficulty from the source

The design of Yingmi museum exhibition lecturers is full of "easy-to-disinfect" ideas, avoiding any problems caused by design flaws in disinfection:
Waterproof and sweat-proof materials: The shells of i7 and C7S have been treated with IP54 level waterproof and sweat-proof processing. Even if wiped repeatedly with alcohol cotton pads during disinfection, the equipment will not be damaged, and it can prevent sweat from seeping into the internal parts of the equipment and causing bacterial growth; In Xiamen Gulangyu Museum (in a humid coastal environment), the Yingmi lecturers were used for half a year, and no moldy conditions occurred inside.
No screen or few-screen design: Some teams use E8 lecturers, to reduce screen contact, only the necessary indicators are retained, reducing the difficulty of disinfection; The C7S with a screen has its surface covered with anti-fingerprint and antibacterial film, not only reducing fingerprint residues but also inhibiting bacterial growth. After being touched by overseas users, the fingerprint traces are 60% less than those of ordinary screens, making disinfection much more convenient;
Lightweight and easy to clean: The i7 lecturer weighs only 20 grams, and the C7S only 25 grams. When staff disinfect, it is convenient to take, and it will not cause omissions due to the heavy equipment; The edges of the equipment have been rounded, without sharp protrusions, and the alcohol cotton pads can easily cover all surfaces.

2. Disinfection Process: Standardized operation, every step has standards

Yingmi provides the "Lecturer Disinfection Operating Manual" to cooperating museums, clearly stating the operation standards, time, and tools for each step, ensuring that whether it is self-disinfection or manual disinfection, there will be no compromise:
The first step: Recycle inspection: After users return the equipment, staff or self-service systems first check if the equipment is damaged or stained. If there are obvious stains (such as food residues), they should be wiped clean with water-soluble cleaning agents first;
The second step: Ultraviolet disinfection: Put the equipment (including headphones) into the ultraviolet disinfection chamber and irradiate for 30 minutes (set according to the bacterial killing standard, less than 20 minutes cannot completely kill bacteria);
The third step: Alcohol wiping: After taking out the equipment, use 75% medical alcohol cotton pads to wipe the buttons, screen, charging interface, and the inner side of the ear罩 of the headphones repeatedly 3 times；
The fourth step： Drying and storage： The disinfected equipment is placed in a ventilated and dry storage cabinet to avoid bacterial growth in humid environments； The headphones are placed separately in a dust-proof cover storage box to prevent secondary pollution；
The fifth step： Record and publicize： The disinfection time， equipment number， disinfection personnel (or self-service system number) are recorded in a table or background system for users to query.
The staff of the Chinese National Museum said： "Before， the disinfection process I formulated was very casual. Since using Yingmi's manual， every step has standards， and when overseas users ask about the disinfection details， we can explain clearly， and the complaint rate has dropped by 80%."

3. Special Scene Disinfection： Responding to High Passenger Flow and Sensitive Needs

During special exhibitions in museums， tourist seasons， or when receiving elderly， children， and people with sensitive constitutions， Yingmi's disinfection process will be further upgraded：
High passenger flow periods： Increase the disinfection frequency， such as disinfecting once every 2 hours during normal times and once every hour during peak seasons； The power of the ultraviolet lamps in the self-service rental and sale cabinets is increased to ensure the efficiency of disinfection； Additional staff are provided to conduct secondary inspection and disinfection of returned equipment to avoid missed disinfection；
Sensitive population needs： Provide independently sealed and packaged disinfection headphones， which can only be used by one person after opening， and be collected and disinfected by staff separately； For children users, we provide children-specific headphones with smaller sizes. The inner side of the ear cups is covered with one-time use antibacterial stickers, further reducing the risk of infection. When Anna took Swedish primary school students to visit the Chinese National Museum, she provided each child with a one-time use antibacterial sticker. "The parents' feedback was particularly good. They said it was even more considerate than the experience in their own country's museums."

IV. Real Feedback from Overseas Users: Disinfection is Reliable, Visiting the Exhibition is Comfortable

The disinfection effect of Yingmi's museum audio guide devices is not achieved through publicity, but verified through the real experiences of overseas users:
"During my first rental of YingmiC7S at the Suzhou Museum, I was reassured after seeing the disinfection record. The headphones were very clean, without any odor, and I didn't feel uncomfortable wearing them throughout the exhibition. When I rented the audio guide device at other museums before, there was dust in the headphones. This time, the disinfection details of Yingmi surprised me. From now on, when visiting Chinese museums, I will only choose Yingmi's equipment." — Dutch Sinology scholar Yang Ke
"Taking my child to visit the Chinese National Museum, I applied for disposable earplugs and children's headphones. The staff also showed the disinfection process. My child listened to the 'Silk Road Cultural Relics' explanation wearing the headphones, and was very concentrated. I didn't have to worry about hygiene issues. The disinfection done by Yingmi was more meticulous than many museums in Japan, and this was a huge plus." — Japanese tourist Sato
"In Dubai's Natural History Museum, I rented Yingmii7. The headphones were disinfected with ultraviolet light, and I felt very at ease wearing them. The Middle East has high hygiene requirements, and Yingmi's disinfection process fully met our expectations. Even the touch labels were wiped very clean. When visiting the exhibition, I didn't have to constantly worry about 'Are there any bacteria?' and could focus on the details of the cultural relics." — Dubai tourist Ahmed

V. Why Can Yingmi Do a Good Job in Disinfecting Museum Audio Guides?

Many brands consider "disinfection as an additional service", but Yingmi regards it as the "core experience". The reason behind this is the 15-year experience accumulated in serving global users:
Understanding the needs of overseas users: Yingmi has long served overseas tourists, knowing that their emphasis on hygiene is far greater than that of domestic users, especially those from Europe, America, and the Middle East. They have higher requirements for the transparency and thoroughness of the disinfection process;
Having a mature disinfection system: From disinfection tools (ultraviolet disinfection chambers, medical alcohol cotton pads) to operation manuals, and to the background record system, all are mature solutions after years of refinement, not hastily assembled;
Deep cooperation with museums: Yingmi will adjust the disinfection plan according to the museum's visitor flow and exhibition characteristics. For example, at the Suzhou Museum with dense exhibits, the frequency of touch label disinfection is increased; at the Chinese National Museum with a large visitor flow, more disinfection personnel are added to ensure no interruption at each stage.

VI. Conclusion: Security is the foundation of the museum audio guide experience

For overseas users, the core of the museum audio guide is "helping you understand the artifacts", but the prerequisite is "using it with peace of mind" - without worrying about whether the headphones are clean or whether the equipment has been disinfected. Only then can you focus on experiencing the history and culture behind the artifacts.
Yingmi has been providing voice-guided tours for 15 years. It is not just about "whether it can explain", but more about "whether it can make users feel at ease". From ultraviolet disinfection to alcohol wiping, from transparent recording to independent packaging, every disinfection detail is designed to ensure that overseas users, in the museum, do not have to worry about hygiene issues, but can only focus on the artifacts in front of them and the explanations in their ears.
The next time you enter the Suzhou Museum, the China National Museum, or the Dubai Natural History Museum overseas, and see the Yingmi museum audio guide, you no longer need to hesitate about hygiene issues - it has been thoroughly disinfected and is waiting to help you understand the story of each artifact.
