How to Clean the Speaker on Xiaomi Phone at Home: 5 Proven Ways

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

Xiaomi’s smartphone speakers (including the Redmi Note 12, POCO X5, Mi 11, and others) accumulate dust, fabric fibers, and even skin particles over time. This is inevitable: when talking, listening to music or watching videos, air passes through the speakers, which carries the smallest pollution, and the problem is especially rapid in users who carry the phone in their pants pocket or often use it on the street.

The first signs of clogging are muffled sound, wheezing when playing bass or the complete disappearance of sound in one of the speakers (in models with stereo sound, for example, Xiaomi 13 Pro or Redmi K60). Sometimes the problem is disguised as a software failure, but if after rebooting or resetting the sound is not restored, the mechanical locking of the speaker membrane is to blame.

Xiaomi doesn't have a formal procedure for cleaning speakers at home, but that doesn't mean the problem is unsolvable. The main thing is not to use aggressive methods (such as blowing compressed air under high pressure) that can damage the membrane or break the diffuser. We tested 5 safe ways and selected those that do not require disassembly of the phone and are suitable even for beginners.

When cleaning the speaker is really needed: symptoms and diagnosis

Before you start cleaning, make sure that the problem is the contamination, not a software failure or hardware breakdown.

• 🔊 Check the sound at maximum volume: if wheezing or distortion is amplified, it is a sign of mechanical membrane locking.
• 📱 Reboot your phone: Sometimes the sound disappears due to a temporary failure in the phone. MIUI (especially after updates).
• 🎧 Connect headphones: if the sound in them is clean, and through the speakers – no, the problem is precisely in them.
• 🔧 Run the hardware component test: type in ##4636###, select Hardware testing → Audio.

If the test shows that the speakers are working, but the sound is still distorted, it's time to clean. Except that if the phone falls or gets wet, cleaning can aggravate the problem (for example, when the membrane detachs after a blow), in which case it is better to contact the service.

⚠️ Note: Do not confuse clogging of the speaker with damage to the mesh (for example, after a fall). If the mesh is deformed or torn - cleaning will not help, you need to replace the module.

Method 1: Toothbrushing (the safest method)

This method is suitable for surface cleaning and removal of dust from the speaker grid.

• 🪥 Soft toothbrush (new or formerly used but clean).
• 💡 Lantern (for illumination of pollution).
• 🧴 Alcohol wipes (for degreasing the body).

Step-by-step:

1. Turn off your phone to avoid accidental tapping.
2. Hold the flashlight to the speaker at an angle - so you can see the pollution better.
3. Carefully, without pressing, brush the speaker along (not across!) the ribbed structure with a grille. Movements should be short and frequent.
4. To remove dust from the recesses, use a dry cotton swab (do not wet it!).
5. Wipe the body around the speaker with an alcohol napkin to remove greasy traces.

This method removes up to 70% of surface contaminants, but it won't help if the dust has penetrated deep under the grid.

Method 2: Cleaning with tape or tape

If fabric fibers have accumulated in the dynamics (e.g. from a pocket of jeans), they can be removed using paint tape or stationery sticky tape, which is effective for models with large mesh perforations (e.g., Xiaomi 12T or Redmi Note 11 Pro+).

How to do this:

1. Cut a small piece of scotch (about 1×1 cm).
2. Apply it with a sticky side down to the speaker grid and slightly press (don't press!).
3. Take the tape off in a sharp movement - it will capture the fibers and some of the dust.
4. Repeat 2-3 times, using a new piece each time.

⚠️ Important: Do not use regular stationery tape - its glue can leave traces on the case. It is better to take a paint (blue or green) or a special tape to clean the objects of the photo.

💡

If after cleaning with tape there are sticky traces, wipe the body with a napkin dipped in isopropyl alcohol (at least 70%).

Method 3: Minimum power vacuum cleaner (for deep cleaning)

This method is more risky than previous ones, but allows you to remove dust from the deep layers of the speaker, where the brush will not get, suitable for models with built-in water protection (IP53 and higher), such as the Xiaomi 13 Lite or POCO F5.

What you need:

• 🪛 Vacuum with power adjustment (or car vacuum cleaner).
• 📏 Nozzle with a narrow nozzle (you can use the nozzle to clean the keyboard).
• 🧲 Magnet (optional, to check for metal particles).

Instructions:

1. Install the minimum power on the vacuum cleaner (no more than 20-30% of the maximum).
2. Bring the nozzle to the speaker at a distance of 5-7 mm (not close!).
3. In brief pulses (1-2 seconds) "suck" the dust. Do not hold the nozzle in one place for longer than 3 seconds.
4. After cleaning, check the sound – if the wheezing is left, repeat the procedure or proceed to the next method.

⚠️ Warning: Never use a compressor or compressed air can - a pressure jet can tear the speaker's membrane! vacuum cleaner works on suction, so safer.

Method 4: Ultrasonic cleaning (for advanced users)

If conventional methods have failed and the sound is still wheezing, you can try an ultrasonic bath, which is only suitable for IP67/IP68 waterproof phones (such as the Xiaomi 13 Pro or Black Shark 5 Pro) and requires caution.

What do you need?

• 🛁 Ultrasonic bath (you can buy inexpensive on AliExpress).
• 💧 Distilled water (not tap water!).
• 🧴 Silicone lubricant (for processing seals after cleaning).

Step-by-step process:

1. Turn off the phone and remove it. SIM-map.
2. Pour distilled water into the bath (temperature not higher than 30 ° C).
3. Put your phone in the tub with the speaker down for 10 to 15 seconds. Don't turn on the ultrasound any longer!
4. Take out the device and shake off the water.
5. Place your phone in rice or silica gel for 24 hours to dry.
6. Then, put the stains on the stains (if any).

⚠️ Warning: This method voids warranty and can corrosion contacts if the phone does not have factory waterproofing!

Method 5: Software Diagnostics and Sound Calibration

Sometimes the problem isn't the pollution, it's the software settings that are failing, like when you update MIUI, you might lose the uniformity of the sound in the stereo speakers.

How to reset the sound settings:

1. Go to Settings → Sound and vibration → Advanced settings.
2. Select Reset Sound Settings (in some versions of MIUI, this option may be called Reset by default).
3. Reboot the phone.

If that doesn’t help, try calibrating the speakers through the engineering menu:

1. Enter the dial number ##3644633##.
2. Select Hardware Testing → Audio → Speaker Test.
3. Follow the instructions on the screen to test each speaker.

If you calibrated the sound better, the problem was the software settings, and if you didn't, go back to the mechanical cleaning methods.

💡

Before any manipulation with the speakers, be sure to check the warranty status of the phone. If the warranty is valid, it is better to contact the Xiaomi service center - self-cleaning can cancel it.

What not to do when cleaning the speakers Xiaomi

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

• 🚫 Blowing out the mouth - saliva will fall on the membrane and cause corrosion.
• 🚫 Using needles, toothpicks or paper clips – they will pierce the diffuser.
• 🚫 Cleaning with wet wipes or alcohol - the liquid will penetrate the mesh and spoil the speaker.
• 🚫 Disassembly of the phone without experience – on Xiaomi models, speakers are often glued, and they are easy to tear off.
• 🚫 Using a hair dryer or heating – this deforms plastic parts.

If you doubt your abilities, it is better to contact the service.The cost of cleaning speakers in official centers Xiaomi starts from 800 rubles, which is cheaper than repair after a failed self-cleaning.
