How to Clean the Speaker in Xiaomi Phone: Safe Methods and Prohibited Techniques

Speakers in Xiaomi smartphones get clogged with dust, villi and dirt particles over time, leading to sound distortion, volume reduction or complete disappearance of bass. Especially the problem for models with open grilles — Redmi Note 10 Pro, POCO X3 Pro or Mi 11, where dust penetrates more actively. But even in sealed flagships like Xiaomi 13 Ultra over time, garbage accumulates inside the acoustic holes.

Cleaning speakers is a delicate procedure. Misconduct can damage the membrane, impair the sealing of the body or short circuit when moisture is injected. In this article, we will discuss 5 proven cleaning methods (including methods without disassembling the phone), list prohibited means that destroy the speakers, and give recommendations for prevention, and you will learn how to diagnose the problem and when to contact the service center.

Signs of clogging speakers in Xiaomi

Before you start cleaning, make sure that the problem is in the speakers, not in the software failure or damage to the audio chip.

• 🔊 The sound is quieter, especially at low frequencies (bass disappears completely).
• 🎵 Wheezing or crackling when playing music/calls.
• 📱 Vibration of the body with loud music (dust interferes with the normal operation of the membrane).
• 👁️ Visible dirt or dust in the speaker grille (watch under bright light).
• 🔄 The problem is manifested only in one dynamic (for example, the upper one works normally, and the lower one wheezes).

If symptoms have occurred after a phone drop or fluid is injected, cleaning may not help - you will need a diagnosis in the service.

⚠️ Attention: If the sound is completely lost (no speaker makes any sounds), the problem may be in the audio codec or the plume.

What can not be used to clean the speakers Xiaomi

Many of the "folk" methods that are suggested in the forums are actually dangerous for speakers.

• 💦 Water and liquids: even a drop can cause contact corrosion or membrane sticking. Alcohol and wet wipes are also prohibited.
• 🧲 Magnets: speakers contain magnetic elements, and a strong magnetic field can demagnetize them.
• 🔥 Compressed air (cylinders): A strong flow can tear the membrane or drive dust deeper.
• 🪡 Needles, toothpicks, paper clips: the risk of puncturing the membrane or scratching the grille.
• 🧴 Abrasives: toothpaste, soda, cleaning powders scratch the coating.

Also, you should not use a vacuum cleaner, which can create too much traction and damage the internal parts. If you see tips for "mouth blowing" ignore them: saliva contains enzymes that corrode metal contacts.

Method 1: Scotch cleaning (for surface dust)

This is the safest method, and it's suitable for removing dust and fine debris from the speaker's outer grille, and it doesn't take a phone to disassemble and takes less than a minute.

Step-by-step:

1. Take paint tape (or regular stationery, but not too sticky). Cut the strip 3-4 cm long.
2. Gently glue it to the speaker grille, slightly pressing your finger.
3. In a sharp movement, tear off the scotch - dust and villi will remain on the sticky side.
4. Repeat 2-3 times until the scotch is clean.

The method works for models with open grilles: Redmi 9, POCO M3, Mi A3. For phones with small holes (for example, Xiaomi 12T), it is better to use other methods.

Turn off the phone.

Use only paint or weakly sticky scotch

Don't press the scotch too hard.

Method 2: Toothbrush with soft bristles

If the dust is deeper than Scotch can get, a soft toothbrush will help.

• 🪥 The bristles should be synthetic (not natural) and very soft.
• 🔘 The size of the head is no more than 1.5 cm to climb into the corners of the grille.
• 🚫 Do not use electric toothbrushes – vibration can damage the membrane.

How to clean:

1. Turn off the phone and put it on a flat surface.
2. Carefully, without pressing, brush the speaker along the holes (not across!).
3. For better effect, tilt the phone slightly so that dust falls out under the influence of gravity.
4. Repeat 3-4 times, then check the sound.

For models with stereo speakers (such as the Xiaomi 11T Pro), clean both speakers one by one. If the brush doesn't work, move on to deeper methods.

💡

Before cleaning, take a photo of the speaker grille under the magnifying glass - so you will see how effective the chosen method is.

Method 3: Cotton swab + isopropyl alcohol (for persistent contaminants)

This method is suitable for removing greasy spots or sticky contaminants, but requires caution. Important: use only isopropyl alcohol 90%+ (not medical!) It evaporates quickly and leaves no moisture.

Instructions:

1. Moisten the cotton swab in alcohol, then squeeze the excess (it should be barely wet).
2. Carefully run the speaker on the grille without pressing. Don't touch the membrane inside!
3. Let the alcohol evaporate completely (2-3 minutes), then check the sound.

For models with a waterproof body (Xiaomi 13 Pro, Redmi Note 12 Pro+), the risk is less, but still do not overdo it with moisture. If after cleaning the sound is worse, then the alcohol got inside, and you need to dry the phone in rice or silica gel for 12 hours.

⚠️ Warning: Never use hard-base ear sticks, they can pierce the safety net. Only take sticks with a plastic limiter.

Method 4: Reverse traction vacuum cleaner (advanced method)

If the previous methods didn't work, you can try to blow out the dust with a vacuum cleaner.

• 🌀 Use only reverse traction (blowing) mode if it is in your vacuum cleaner.
• 📏 Keep the nozzle at a distance of 5-7 cm from the speaker.
• 🔇 Set minimum power to avoid damaging the membrane.
• 🛑 Do not use household hair dryers – they create too hot airflow.

Algorithm of action:

1. Turn off the phone and take off the case.
2. Tilt the phone with the speaker grille down (at an angle of 45°).
3. With short pulses (1-2 seconds), blow air along the grille.
4. Repeat 2-3 times, then check the sound.

This method is effective for large-hole models (Redmi K40, POCO X4 Pro) and is ineffective for small-perforated phones (Xiaomi Civi).

Method 5: Disassembly of the phone (extreme case)

If all the external methods fail, you have to take the phone apart and clean the speaker from the inside, and it's a risky move that requires expertise and tools.

• 🔧 You're gonna need a plastic spatula, a screwdriver. T3/T5 (depending on the model) and screen suction cup.
• 📱 Risk of damage to plumes, tearing off flexible cables or loss of leakage (for waterproof models).
• ⚖️ The warranty will be cancelled upon opening the hull.

Step-by-step (for experienced users):

1. Turn off the phone and remove it. SIM-map.
2. Heat the back cover with a hairdryer (temperature not higher than 60°C) to soften the glue.
3. Carefully tuck the lid with a plastic spatula, starting at the corner.
4. Unplug the battery plume, then find the speaker (usually it is glued or screwed).
5. Clean it with a soft brush or cotton swab dipped in alcohol.
6. Put the phone back together, check all the plumes.

For models with adhesive screen (Xiaomi 12, Redmi K50) the analysis is more difficult - you will need a special mediator and a skill to not damage the display.

💡

Disassembly of the phone is a last resort, 80% of the time it can be solved by external cleaning. If you've never taken a smartphone apart, it's best not to risk: the cost of replacing the speaker in the service (300-800). ₽) lower than repairs after a failed breakdown.

Prevention of speaker clogging

To keep the speakers in your Xiaomi clean for longer, follow these tips:

• 📱 Use cases with speaker protection (for example, with raised edges).
• 🧴 Avoid carrying your phone in pockets with coins, keys or sand.
• 🚿 If the phone is waterproof, flush the speakers with fresh water after being hit by sea or chlorinated (then dry for 2-3 hours).
• 🔇 Regularly (once a month) clean the grille with scotch or brush.
• 🎵 Do not put the phone speaker down on soft surfaces (sofa, bed) - villi are clogged into holes.

For models with an active cooling system (Black Shark, POCO F4 GT), clogging of the speakers is faster due to constant blowing, in which case cleaning should be carried out more often - every 2-3 weeks.

Important: If you often listen to music at maximum volume, the speakers wear out faster. Dust is attracted to the vibrating membrane more actively, so clean them after each "marathon" of listening.
