Quiet sound in conversational dynamics is one of the most common problems faced by owners of smartphones Xiaomi, Redmi and POCO. Over time, the speaker is stuffed with dust, villi from the pocket and skin fat, which significantly reduces the volume and distorts the voice of the interlocutor. Many users mistakenly believe that this is a software glitch, and begin to reset, although the problem is solved by simple physical cleaning.
In this article, we will discuss in detail how to clean the hearing speaker on a Xiaomi phone without damaging the protective mesh and internal components. You will learn about safe methods, necessary tools and actions that are strictly prohibited when maintaining the acoustic system of a smartphone.
Following proven algorithms will help restore crystal audibility and extend the life of the device, and it's important to understand that regular acoustic maintenance is not just a matter of comfort, but also a necessity for maintaining communication quality.
Signs of pollution of the auditory dynamics
The first signal that it's time to clean the audio speaker on Xiaomi is to turn down the volume. The interviewer may complain that you're speaking quietly, or you won't hear it clearly even at maximum volume. Often the sound becomes deaf, like the phone is under a blanket, even though it's not in your pocket.
Notice the visuals, and if you look at the top of the screen, where the earpiece grid is, you see a gray plaque or a dark dot, and it's compressed dust, which eventually turns into a dense plug that blocks the sound wave.
Sometimes the problem is a cod or wheezing during a conversation, which indicates that the speaker membrane is vibrating unevenly due to partial overlapping of the hole or small particles entering the body, and ignoring these symptoms can lead to a complete failure of the component.
- 🔇 The sound is quieter even at 100% volume.
- 🗣️ Interviewers ask questions or complain about poor hearing.
- 📉 There were extraneous noises, wheezing or distortions of the voice.
- 👀 Visually noticeable gray plaque or contamination in the grid speaker.
Necessary Tools for Safe Cleaning
Before you start the procedure, you need to prepare the right arsenal. Using inappropriate items can damage the safety net or push dirt deeper. To clean the speaker properly, you need the minimum set of tools available.
The main tool will be a soft brush with natural pile, for example, from makeup or for drawing, it allows you to sweep dry dust without the risk of scratching the body, and isopropyl alcohol is also indispensable, which degreases the surface and quickly evaporates without leaving traces.
To remove sticky contaminants, a special cleaning clay (cleaning gel) or sticky tape is ideal. It is important to avoid using cotton swabs with tight padding, as they can push dust inside or leave the villi.
- 🖌️ Soft brush with long pile for dust sweeping.
- 💧 Isopropyl alcohol (concentration 70% or higher) for degreasing.
- 🧼 Cleaning clay or sticky tape to remove fine debris.
- 🔦 Lantern for a thorough inspection of the speaker grid.
⚠️ Warning: Never use sharp metal objects such as needles or pins to pick through the speaker grid.You may damage the membrane or puncturing the protective shield, resulting in irreversible breakage.
Preparation of the smartphone for the cleaning procedure
Security is priority number one. Before you clean the hearing speaker on Xiaomi, you need to turn off the smartphone, which will eliminate the risk of short circuit if moisture accidentally hits the contacts, and prevent accidental pressing.
If you have a protective film or glass on your phone, make sure that they don't block access to the speaker. In some cases, the protective coatings are unstuck over time in the mesh area, creating an additional barrier to sound. Remove the case to have full access to the ends of the device.
Examine the speaker area in good light, preferably with a flashlight, which will help assess the degree of contamination and choose the most suitable cleaning method. If only dry dust is visible, dry cleaning will suffice, but the presence of greasy plaque will require the use of alcohol.
☑️ Checklist before cleaning
Mechanical method of cleaning without liquid
Dry is the safest method and the best way to maintain it on a regular basis, so take a soft brush and walk through the speaker grid with light, sweeping movements, and move from center to edge to push the dust outward rather than push it deeper.
After brushing, use sticky tape or special tape. Stick a piece of tape to the speaker area and press it gently, then sharply tear it off. Repeat the procedure several times with new pieces of tape until the sticky surface no longer has dirt particles, a method that effectively removes villi and fine dust.
You can use a cleaner clay to clean it deeper, and you can apply a little bit of material to the net, and you can press it slightly, and then you can remove it, and it can penetrate the grid cells and pull out the impurities that you can't get with the brush, and it's especially effective for models with fine mesh.
- 🌬️ Dispose of dust from the inside out.
- 🩹 Use a sticky tape to collect small particles.
- 🧽 Apply cleaning clay for deep cleaning of cells.
- 🔄 Change pieces of tape or clay as you contaminate.
What to do if there is dust inside?
Wet cleaning using isopropyl alcohol
If the dry method didn't work and you see a greasy coating on the grid, you need to use wet cleaning. Isopropyl alcohol is ideal for this, because it does not conduct current in a dry state and evaporates quickly. Do not pour liquid directly on the phone under any circumstances!
Lightly moisten the corner of soft lilac or cotton swab (gently pressing it) with alcohol. Wipe the speaker mesh with light movements, trying not to wet the screen around. Alcohol will dissolve the fat deposits, after which they will need to be removed with the dry part of the tissue.
After treatment with alcohol, allow the device to dry for 5-10 minutes before turning on. Make sure there is no moisture left in the grid. This method allows you to restore the original volume and remove the effect of "muffled" sound caused by the greasy film.
⚠️ Warning: Avoid using tap water or wet hand wipes. They contain minerals and fragrances that, when dried, will leave white coating or may cause corrosion of the speaker's contacts.
💡
Use only high-purification isopropyl alcohol (from 90%), as it evaporates faster and leaves no swelling, unlike medical alcohol or vodka.
Software Methods and Sound Cleaning
In addition to mechanical cleaning, Xiaomi owners can use software methods. There is a popular but controversial way to clean with sound waves of a certain frequency. The principle is based on the fact that low-frequency sound causes a vibration of the membrane, which theoretically can push dust.
You can play a YouTube video with a request for "clean speaker sound" or use special applications from Google Play. Volume is set to maximum, and the phone is placed on a hard surface for 1-2 minutes. Vibration helps to dislodge dry dust.
But it's worth noting that this method is only effective for dry, unsealed dust, if the speaker is stuffed with fat or compressed dirt, sound cleaning is useless, and, furthermore, long-term sound reproduction at maximum volume can cause the speaker coil to overheat.
| Method | Efficiency | Risk of damage | Recommended frequency |
|---|---|---|---|
| Dry cleaning (brush) | Tall (for dust) | Low. | As necessary |
| Sticky ribbon | Medium (for pile) | Low. | Once a month |
| Isopropyl alcohol | High (for fat) | Medium. | With heavy pollution |
| Sound vibration | Low/Controversial | Medium (overheating) | Not often recommended |
💡
Mechanical cleaning with soft tools is always more effective and safer than trying to blow out dirt with sound or compressed air.
What is absolutely impossible to do
The desire to quickly clean the auditory speaker on Xiaomi can lead to fatal errors, the most common of which is the use of compressed air from cans. A powerful jet can drive dust even deeper into the body or even damage the thin membrane of the speaker with pressure.
The vacuum can be too strong for the miniature components of the smartphone and cause internal connections to break off, and static electricity from the plastic vacuum tube is dangerous for electronics.
Don’t try to disassemble the phone to get to the speaker from the inside if you don’t have experience. In modern Xiaomi models, accessing the speaker speaker often requires removing the screen, which can damage it and lose moisture protection.
- 💨 Do not use compressed air under high pressure.
- 🌪️ Do not use a household vacuum cleaner to clean electronics.
- 🔪 Do not pick the net with needles, knife or toothpicks.
- 💦 Do not pour the speaker with liquid directly from the container.
⚠️ Attention: If after a thorough cleaning the sound is not restored, the problem may be hardware, the speaker or the plume may have failed.
Pollution prevention and care
To avoid the question of "how to clean the hearing aid" getting up too often, it's important to keep a check on prevention: don't carry your phone in your pockets with any fuzzy fabric, small change or crumbs, and the ideal solution is to carry your smartphone in a separate compartment of your bag or a cover with a protective side.
Regularly, at least once every two weeks, wipe the top of the screen with dry soft cloth, which will prevent the accumulation of skin fat, which is the main cause of the formation of sticky plaque on the mesh, and simply wiping reduces the risk of deep contamination by 80%.
Use protective films that have cutouts under the speaker, but do not cover it completely. Some users paste a small piece of a special dust mesh over the mesh, which traps large dust and easily changes.
