How to Clean the Speaker on Xiaomi Mi 8: The Complete Guide

The volume drop and wheezing in the Xiaomi Mi 8 is a common problem faced by the owners of this popular smartphone after a year or two of active use. The main reason for the deterioration in sound quality is most often the banal clogging of the speaker grid with fine dust, pile from pockets and skin fat. Over time, these microparticles compress, forming a dense plug that physically prevents the passage of the sound wave, which causes the interlocutors to stop hearing you, and the music sounds deaf.

Before you carry the device to the service center or buy a new module, you should try to do self-cleaning. In most cases (about 90%) you can return the previous volume with simple means, if you act carefully and follow a certain sequence of actions. It is important to understand that the internal device Xiaomi Mi 8 involves protective membranes that are easily damaged by aggressive chemistry or rough mechanical impact.

In this article, we will discuss proven methods that will help you safely remove contamination. We will look at both dry cleaning methods and methods using minimal moisture, and also discuss what you can not do to keep the electronics from failing completely.

Diagnosis of the problem: dust, moisture or breakage

The first step before any manipulation is to determine exactly what the fault is, and it's not always a quiet sound that means the net is filled with dust, sometimes it's a software failure, or worse, it's moisture getting inside the case, and if you've recently been swimming in the sea or been caught in a heavy rainstorm without protection, the sound may be lost due to oxidation of the contacts or swelling of the protective membrane.

To understand exactly what happened to your Mi 8, take a visual look at the spoken and main speakers in good light, preferably using a magnifier or macro shot of another phone. Pay attention to the grid color: gray or black plaque indicates a buildup of dirt, and whitish spots may indicate dried salt deposits after water hits. It is also worth checking the sound settings in the Settings → Sound and vibration menu, making sure that the volume sliders are twisted to the maximum.

⚠️ Attention: If after cleaning the sound did not appear, and the speaker emits a crack or complete silence, there may have been a break in the plume or burned the speaker coil.

It's also important to eliminate software conflicts. Try playing the audio file through different applications: built-in player, browser, instant messengers. If one application has sound and another does not have a problem with the code of the program, not the hardware. However, if wheezing is heard everywhere and accompanied by visual pollution, mechanical cleaning is the only right solution to restore functionality.

Preparation of the workplace and tools

The quality of the procedure depends on the preparation. You don't need complex surgical tools, but using the wrong items can lead to scratches on the body or push dirt deeper. The basic rule is cleanliness and good lighting. The best thing to do is work at a desk with a desk lamp to see the smallest details of the speaker grid.

For effective and safe operation, you will need the following materials:

• 🧹 Soft antistatic brush (a new brush for makeup or drawing with natural pile is ideal).
• 💧 Isopropyl alcohol (concentration 90% or higher) or a special spray for cleaning electronics.
• 📏 Toothpick with blunt end or plastic spatula for neat picking.
• 🌬️ Pear for purging (used for cleaning cameras lenses).
• 🧻 A hairless microfiber napkin.

It is strongly recommended not to use ordinary water, as it contains salts and minerals that will leave a conductive plaque after drying. Also forget about cotton swabs: their villi often break off and get stuck in the grid, creating an even more serious problem than the original dust. The use of metal needles is also dangerous - they are easy to pierce the protective membrane of the speaker, after which it will start wheezing forever.

Before starting the procedure, be sure to turn off your smartphone, which will prevent accidental screen turn on, calls or, worse, short circuit if a drop of liquid does penetrate the body, and place the phone on the soft surface with the screen down so that the display does not scratch during operation.

Dry method of cleaning the speaker

The safest way to start anyway is dry cleaning, which removes surface contaminants without the risk of moisture entering the internal components, which is effective if the contamination is not critical and the dust has not compressed into a solid lump, and proceed slowly and without much pressure.

Take a dry soft brush and walk through the speaker grid with light sweeping movements. Movements should be directed from center to edge to drive the dust outward rather than pushing it inward. After that, use a pear: make some strong air chucks into the speaker hole from 2-3 cm away. The sharp flow of air will help to knock out the dust loosened by the brush.

If the dry method didn't work, you can use the "scotch method." Cut a small piece of transparent tape, twist it with a sticky side outside (to get a sticky cylinder), and gently apply a speaker to the grid. The sticky surface will pull out some of the dust and pile that's stuck between the mesh cells. Don't push hard so that the glue doesn't stay on the case.

For more complex contaminants, you can use a toothpick, but with extreme caution: wrap the tip of the toothpick with a microscopic piece of cotton or use a plastic tip. Carefully, without fanaticism, walk through the grid cells, picking out visible lumps of dirt. Here, it is important not to damage the mesh itself, which is quite thin in the Xiaomi Mi 8.

Wet cleaning using alcohol

If dry methods are powerless against a thick layer of dirt or greasy plaque, you'll have to resort to "heavy artillery" - isopropyl alcohol. This substance is ideal for electronics, because it quickly evaporates, leaves no traces and dissolves fats perfectly. The main rule is that the liquid never pours directly on the phone!

Apply a small amount of alcohol to the bristles of a brush or to the edge of a lilac-free napkin. The brush should only be slightly moist, it should not drip. Gently wipe the speaker mesh with circular motions. The alcohol will dissolve the fat and soften the compressed dust. Immediately after treatment with alcohol, blow the pear speaker or leave the phone to dry in a warm place for 10-15 minutes.

There is a popular but controversial method of using the Sound Cleaner app, or analogues, that generate a low-frequency hum. The bottom line is that vibration from the sound pushes water or dust out. The effectiveness of this method in heavy dust pollution is extremely low, since the sound wave cannot move a compressed clump of dirt. However, as an auxiliary after mechanical cleaning, it can help remove moisture residue.

What to do categorically can not be done

In the pursuit of pure sound, users often make fatal mistakes that turn simple repairs into expensive module replacements.The Internet is full of harmful tips that were relevant 20 years ago for button phones, but are fatal for today's smartphones with dense layout and moisture-protective membranes.

Here is a list of things that could kill your Xiaomi Mi 8:

• 🚫 Using a hair dryer: Hot air can melt the glue, holding display and back cover, and damage the battery.The flow of air often drives the dust even deeper.
• 🚫 Vacuum: Static electricity generated by vacuum cleaners can break through the phone's chips, and powerful traction can tear off delicate plumes inside.
• 🚫 Acetone and solvents: Aggressive chemistry instantly corrodes plastic, body paint and dynamic membrane protective coatings.
• 🚫 Blowing out by mouth: Exhaled air contains a lot of moisture, which will only make things worse if the problem was in the water, or create a new one.

⚠️ Warning: Never disassemble the phone completely to clean the speaker unless you have experience. In the Mi 8, the speaker is integrated into the lower board, and accessing the back of the phone will require removing the battery, which increases the risk of damage to the plumes and loss of water protection.

Also avoid using compressed air from keyboard cleaners. They often release air under too high pressure and may contain condensation. A sharp surge in pressure can tear the thinnest speaker membrane, and then instead of a quiet sound, you get complete silence or a strong hum.

Prevention and care of acoustics

To avoid the question of “how to clean the speaker on Xiaomi Mi 8” every six months, it is worth sticking to simple rules of operation: dirt enters the phone mainly from pockets of clothes, bags and hands. Regular hygiene of the device will help to keep the sound quality at a high level for a long time.

Once a week, wipe the bottom and top of the phone with dry soft cloth. If you carry your phone in a pocket of jeans with a lot of pile, try to put it up with the speaker or use a protective case with raised sides. Bumper cases are great at protecting the speakers' holes from direct contact with the pile of fabric.

Avoid talking on the phone while eating or in dusty spaces (construction, repairs). Food particles and building dust immediately clog the net. If the phone is wet in the rain, wipe it dry immediately and do not connect to charging until the ports dry out.

💡

Use an ultraviolet phone dryer (UV sanitizer) not only for disinfection, but also to keep ports and speakers dry if you live in humid climates.
