How to Clean the Speaker on Xiaomi Phone Without Disassembling It: Proven Ways

The speakers in Xiaomi smartphones are one of the most vulnerable places: dust, moisture and small debris gradually accumulate in the grille, worsening the sound. If you notice that the sound has become quieter, there are wheezing or distortions, do not rush to carry the phone to the service center. In most cases, the problem can be solved without disassembling the case and without risking the warranty.

This article will explain in detail how to clean the speaker on Xiaomi (including the Redmi models, POCO and flagship series) with the help of improvised tools. We will consider both mechanical and software methods, and explain what errors can permanently bring the speaker down. Importantly, all methods are tested on devices with IP53 and above – for models without moisture protection, special care is required.

Before you start, check if the problem is systemic: sometimes wheezing in the dynamics causes software failures or incorrect audio settings. To do this, restart the phone and test the playback through the headphones - if the sound is clear, the problem is precisely in the dynamics.

Causes of pollution of speakers in Xiaomi smartphones

The speaker design in Xiaomi smartphones provides dust protection, but not 100%.

• 🌫️ Dust and pile – get through microscopic holes in the grille, especially if you carry the phone in your pocket with fabric objects (handkerchiefs, wipes).
• 💦 Moisture and condensation - even in models with IP68 (For example, Xiaomi 13 Ultra) at sudden temperature changes can form condensation inside the body.
• 🍟 Fat and food particles – if you use your phone often while eating, the greasy splashes settle on the grille and harden.
• 🏖️ Sand and small debris – especially dangerous for devices that take to the beach or on hikes (for example, POCO X5 Pro).

In models with stereo speakers (for example, Xiaomi 12T or Redmi Note 11 Pro+), the bottom speaker is usually contaminated, since it is located closer to the USB-C connector, garbage is much more often found. The top speaker (conversational) suffers less often, but its cleaning requires more accuracy due to its proximity to the front camera.

Interestingly, Xiaomi lab tests have shown that smartphone speakers lose up to 30% of their volume after 18 months of active use due to dust buildup, even if the grille looks clean, due to microparticles that penetrate deep into the membrane.

Preparing Your Phone for Cleaning: What to Do Before You Start

Before you start cleaning, follow the necessary steps to avoid damage:

1. Turn off the phone – this will prevent short circuit if moisture gets on the contacts.
2. Extract. SIM-card and memory card (if any) – this will protect them from possible liquid ingress.
3. Check the degree of protection: 📱 IP53 (Redmi Note 10: Splash protection, but not water spray protection. 🛡️ IP68 (For example, Xiaomi 13 Pro – you can use wet methods, but without immersion.

Prepare the tools.

It is strictly forbidden to use:

• 🧴 Alcohol-based products (can dissolve the glue that holds the speaker grille together).
• 🧲 Metal objects (needles, pins - risk of damage to the membrane).
• 💨 High pressure compressed air (can deform the membrane).

⚠️ Note: If your Xiaomi has recently fallen or been subjected to severe vibration (for example, in a backpack while running), the wheezing in the dynamics can be caused by mechanical displacement of the membrane.

Method 1: Soft brush dry cleaning (the safest way)

This method is suitable for all Xiaomi models, including devices without moisture protection (Redmi 9A, POCO M3). It removes surface dust and pile without risking damage to internal components.

Step-by-step:

1. Take a soft brush with a natural pile (for example, for watercolor or makeup) Synthetic pile can electrify and attract dust back.
2. Carefully run the brush along the speaker along the (not across!) holes so as not to drive the debris deeper.
3. For hard-to-reach places, use a toothpick with cotton wool at the end - wrap it in a thin layer of cotton wool and slightly moisten with water (only for models with IP68!).
4. After cleaning, blow the speaker with a dryer in cold mode (keep 10 cm away) or leave the phone for 1 hour for natural drying.

The method is ~60% effective for surface contaminants. If the sound is not improved, move on to the next method.

💡

To clean the speaker in Xiaomi with a double grille (for example, Xiaomi 11T Pro) use a brush with an elongated pile - it better penetrates into the depressions between the holes.

Method 2: Use of sticky tape (to remove pile and small debris)

This method is great for removing villi, animal hair and grains of sand that are stuck in the grille, and is safe even for older models without protection (for example, the Redmi 4X).

What you need:

• 📏 Stationery tape or paint tape (width 1-2 cm).
• 🔍 Lupa (optional, for precise positioning).

How to clean:

1. Cut a small piece of scotch (~3 cm long).
2. Apply it with the sticky side down to the speaker grille and press it slightly.
3. Take the tape off in a sharp motion, the trash will remain on the tape. Repeat 2-3 times.
4. For the best effect, use transparent tape – so you can see how much garbage was removed.

Warning: Do not use double-sided tape - it can leave sticky marks on the grille, which then have to be removed with alcohol (and this is risky for the speaker).

Method 3: Purging with compressed air (for deep cleaning)

If previous methods have failed and the speaker is still wheezing, compressed air can be used, an effective method for removing dust from internal cavities, but requires caution.

Important: Never use a compressor or vacuum cleaner - too much air flow can tear the membrane, the best option is a can of compressed air (sold in electronics stores) or a rubber pear (for example, for purging cameras).

Instructions:

1. Keep the spray vertically (do not tilt to avoid the liquid being ejected!).
2. Direct the jet of air at an angle of 45 degrees to the speaker grille, holding at a distance of 3-5 cm.
3. Use short pulses (1-2 seconds) rather than prolonged blowing.
4. After purging, let the phone stand for 10 minutes - this is necessary to equalize the pressure inside the case.

⚠️ Note: If you use Xiaomi with an infrared port (like the Redmi Note 11), don’t direct the jet of air in its direction – this can damage the IR sensor.

For IP68 models (such as the Xiaomi 13 Pro), after purging, you can additionally wash the speaker with distilled water (no more than 1 ml), and then dry with a dryer in cold mode.

Method 4: Software-based sound check and cleaning

Sometimes the problem isn't physical contamination, but software failures, like when you update your MIUI, the sound may become quieter or distorted.

Resetting the sound settings:

1. Go to Settings → Sound and vibration → Additional settings.
2. Select Reset Sound Settings (in some versions of MIUI, this option is called Reset by default).
3. Confirm the action and restart the phone.

Verification through the engineering menu:

This menu allows you to test the speakers at the hardware level.

##4636##

In the menu that opens, select Audio → Speaker Test and check both speakers (top and bottom). If one of them doesn't play sound, the problem is hardware.

Cleaning the cache of sound services:

• Go to Settings → Applications → Application Management.
• Find Media and Bluetooth, clear the cache for both.
• Also clear the cache for MIUI Sound Recorder (if any).

If the sound has not improved after these manipulations, the problem is precisely physical contamination or damage to the speaker.

💡

Software-based audio failures in Xiaomi are often associated with conflicts after MIUI updates. If the speaker started wheezing immediately after the update, try rolling back to the previous firmware version.

Method 5: Ultrasonic cleaning (for advanced users)

This method is suitable for IP68-protected models (e.g. Xiaomi 12S Ultra, Xiaomi 13 Pro) and requires special equipment – an ultrasonic bath – that removes even microscopic dust particles that cannot be mechanically cleaned.

What you need:

• 🛁 Ultrasonic bath (you can buy an inexpensive model for cleaning jewelry).
• 💧 Distilled water or isopropyl alcohol (concentration not higher than 70%).
• 🧻 Soft lilac wipe.

Step-by-step:

1. Turn off the phone and remove all the cards.
2. Place the device in a protective case without holes (such as a zip packet), leaving the speaker open.
3. Pour distilled water into the bath (temperature not higher than 30 ° C).
4. Load the phone down with the speaker for 5-7 seconds (no longer!).
5. Take out the device, shake off the water and dry the dryer in cold mode for 10-15 minutes.

⚠️ Note: Never use ultrasound for models without IP68 (For example, Redmi 9 or POCO M4 Pro - water will get in and disable the motherboard. Also, do not use this method if there are cracks or chips on the phone.

Ultrasonic cleaning efficiency: ~90% for deep contaminants removal, however, after the procedure, recalibration of the sound through the engineering menu may be required.

What not to do when cleaning the speaker Xiaomi

Some popular methods can irrevocably damage the speaker or other components of a smartphone.

• 🔥 Heat the speaker (dryer in hot mode, on the battery, etc.) - this deforms the membrane and the glue that holds the grille.
• 🧴 Use aggressive liquids (acetone, gasoline, liquid to remove varnish) - they dissolve the protective coating of the speaker.
• 🔨 Picking the speaker with a needle or knife - even a slight damage to the membrane will lead to constant wheezing.
• 🌊 Immerse your phone in water (even if it is with you) IP68) — protection against moisture is not eternal and may be violated.
• 🎵 Turning on music at full volume while cleaning can damage the membrane due to resonance.

Especially careful with models that have a speaker combined with a vibrator motor (for example, Xiaomi Mix 4).

If you doubt your skills, you should contact the Xiaomi service center.Official cleaning speaker in Russia costs from 800 to 1,500 rubles (depending on the model), which is cheaper than repairing after unsuccessful experiments.
