How to clean the speakers on Xiaomi: from dust, dirt and distortion of sound

Why Xiaomi’s speakers are getting polluted and how it manifests itself

The speakers in Xiaomi smartphones, speakers and headphones are some of the most vulnerable components, and even when used carefully over time, they accumulate dust, pocket fibers, fat deposits and microparticles from the air, especially in models with an open speaker grille (such as the Redmi Note 12 or the POCO X5 Pro), where protection is minimal.

The first signs of contamination are muted sound, wheezing when playing bass or the complete disappearance of high frequencies. In advanced cases, the speaker may begin to "clap" at a volume above 70%, and in the Mi Portable Speaker speakers, there is often a "gurgling" effect due to moisture. If you do not clean the speakers for years, this leads to irreversible damage to the membrane due to corrosion or mechanical wear.

In this article, we will discuss 5 proven cleaning methods, from the most gentle (for beginners) to deep cleaning with the disassembly of the device. All methods have been tested on Xiaomi 13T, Redmi 10C and Mi Smart Speaker, but are suitable for most of the brand’s gadgets. Importantly, before you start, determine the type of contamination – dry dust or sticky plaque (it is more difficult to get rid of).

Method 1: Dry cleaning with brush and tape (for surface contaminants)

This method is suitable for daily cleaning and dust removal from the speaker grille, and is safe even for IP-certified devices (such as the Xiaomi 13 Pro with IP68), as it does not require liquids.

• 🖌️ Soft art brush (synthetic, size 0-2)
• 📏 Stationery Scotch (preferably narrow, 1 cm wide)
• 🔦 Phone flashlight or desk lamp

Instructions:

1. Turn on the flashlight and point the lights at a 45° angle to the speaker grille, which will help you see the dust clumps.
2. Carefully walk the brush along the lattice from the center to the edges. Don't push -- the fibers of the hand are just supposed to sweep away the particles.
3. Cut a piece of tape 3-4 cm long. Stick it to the grille, press it slightly and sharply rip it. Repeat 2-3 times.

⚠️ Warning: Do not use cotton swabs, their fibers may get stuck in the grid, and avoid metal objects (needles, pins) that scratch the protective net.

💡

If the dust accumulates too quickly, check the phone case - often the fault is with the fuzzy materials (like alcantara) and replace it with silicone or fabric with a smooth surface.

Method 2: Compressed air cleaning (for deep contaminants)

Compressed air is effective when dust has penetrated the speaker grille or accumulated in hard-to-reach places (for example, in the Mi Smart Speaker column around the bass reflex).

• 💨 Compressed air cylinder (e.g. Kontakt Chemistry)
• 📱 Smartphone with the “Do Not Disturb” mode enabled (so as not to damage the membrane with a sound wave)

Step-by-step:

1. Hold the sprayer vertically at a distance of 5-7 cm from the speaker. You can not tilt - this can lead to the ejection of liquid!
2. With short presses (1-2 seconds) blow through the grid. Start at the edges, gradually moving to the center.
3. For Xiaomi speakers with a passive emitter (such as Mi Portable Bluetooth Speaker 16W), direct the jet of air parallel to the surface, rather than perpendicularly.

⚠️ Warning: Never use a vacuum cleaner, it creates reverse traction and can pull in the speaker membrane, damaging it. Also avoid cans of freon (they leave an oily coating).

Method 3: Wet cleaning (for sticky contaminants and potassium deposits)

If the speaker is covered with a sticky coating (for example, from hand cream or sweat), dry cleaning will not help. IP-certification (IP53, IP68) The method is safe, but requires caution.

What you need:

• 🧴 Isopropyl alcohol (or Kontakt 60)
• 🧻 Wormless napkin (microfibra)
• 💧 Cotton swab with plastic base (not wooden!)

Instructions:

1. Moisten the cotton swab in alcohol so that it is wet, but not dripping.
2. Carefully walk along the speaker grille with a slight push. For Xiaomi speakers, use circular motions from center to edge.
3. After 2 minutes, wipe the surface with a dry microfiber.
4. Allow the device to dry for at least 1 hour before turning on.

⚠️ Attention: For devices without IP-certification (e.g. Redmi) 9A or POCO M3) Wet cleaning is risky, and in this case, use an alcohol napkin, touching the grille lightly, but not pressing.

Method 4: Cleaning with disassembly of the device (for power users)

If the speaker is completely lost or is making a constant crack, it's likely that the dirt has fallen under the membrane, in which case only disassembly will help, a method only recommended for those who have already had experience in electronics repair.

Tools:

• 🔧 Set of screwdrivers (cross, flat, flat, T3–T5)
• 🧲 Suction cup for screen removal (for smartphones)
• 🔍 loope USB-microscope (for precise operation)
• 🧴 Alcohol and brush (for cleaning internal components)

The step-by-step process (on the example of Xiaomi Redmi Note 11):

1. Turn off the phone and remove it. SIM-map.
2. Heat the back cover with a hairdryer (temperature 60-70°C) and remove it with a suction cup.
3. Unscrew the screws that hold the metal plate over the speaker (usually marked with DIN or SPK).
4. Carefully tuck the speaker in with a plastic spatula and remove it. Clean the membrane with a brush soaked in alcohol.
5. Blow the hole in the case with compressed air and assemble the device in reverse order.

💡

If the speaker continues to crack after disassembly, the problem may be a damaged membrane or detached contacts, in which case a replacement speaker is required (cost for Xiaomi is from 500 to 1500). ₽).

⚠️ Note: When disassembling smartphones with a glue-based battery (for example, Xiaomi) 12T) Don't pull the plumes, they're easy to pull off. Use plastic mediators to separate the components.

Method 5: Software Diagnostics Before Cleaning

Before you start a physical cleanup, make sure that the problem is the contamination, not the software failure.

1. Run the speaker test through the engineering menu: ##4636## Select Audio → Speaker Test.
2. If the distortion only occurs at high frequencies (e.g., when playing 10-15 kHz), it indicates contamination of the membrane.
3. Install the Speaker Clean app from Google Play. It plays special sound waves that can shake off the dust from the membrane (effective for mild contaminants).

If the test shows that the speaker is not making sound at all, the problem may be:

• 🔌 The detached plume (after falling)
• 🔋 Faulty audio chip (requires flashing or repair)
• 💧 Corrosion of contacts (if the phone was in contact with moisture)

What not to do when cleaning the speakers Xiaomi

Some folk methods can irrevocably damage the dynamics, and this is strictly forbidden:

• 🧹 Use a vacuum cleaner – it creates static electricity and can tear out the membrane.
• 💦 Wash the speaker with running water or soak in liquid.
• 🔥 Heat the speaker with a hairdryer at maximum power - this deforms the membrane.
• 🧲 Use magnets to “pull” metal dust – they violate the calibration of the speaker.
• 🧼 Clean with soap solution – it leaves a film that attracts new dust.

Also avoid perfumed alcohol wipes - they contain oils that corrode the adhesive membrane bases. For Xiaomi speakers, don't use abrasive sponges (even soft ones) - they scratch the protective coating of the case.
