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

The top speaker (conversational) in Xiaomi smartphones is one of the most vulnerable places, and over time it gets clogged with dust, fat deposits and small debris, resulting in muffled sound, wheezing or a complete lack of voice. Especially relevant problem for models with a narrow speaker grille: Redmi Note 10/11/12, POCO X3/X4, Mi 11 Lite and others.

Many users mistakenly think that cleaning requires a complete disassembly of the phone, and in fact, 80 percent of the time, you can get a clear sound back without opening the case using the tools you can use, and the key is to be careful not to damage the membrane of the speaker or microphone, which is often located nearby.

In this article, you'll find step-by-step photo instructions, comparisons of effectiveness, and unique pollution prevention tips that are not in standard manuals, all of which are tested on real devices and require no special skills.

The reasons for the clogging of the top speaker on Xiaomi

Before you start cleaning, it's important to understand why the speaker gets polluted so quickly.

• 🌪️ Design features: most Xiaomi grille speakers are narrow slits (0.1-0.3 mm), which are easily clogged with dust. For example, in the Redmi Note 10 Pro holes are vertical, which accelerates the entry of debris when carrying the phone in your pocket.
• 💦 Sweat and skin fat: When talking, the speaker contacts the ear, and moisture and fatty deposits stick to the grate, creating a sticky layer that attracts dust.
• 📦 Packaging and transportation: New phones are often stored in high-dust warehouses, and even out of the box, the speaker can be partially clogged with microparticles of packaging material.
• 🚗 External environment: If you use your phone frequently on the street, in public transport or in dusty rooms, the risk of clogging increases 3-4 times.

Interestingly, according to service centers, Xiaomi Mi A3 and POCO F1 lead in the number of complaints about the speaker because of too fine perforation of the grille, while models with a protective glass Gorilla Glass 5 (such as Mi 11) are less likely to suffer from this problem due to the smoother surface around the speaker.

Signs of a clogged speaker: how to recognize the problem

Not always a muted sound means that the speaker is clogged, sometimes software failures or membrane damage are to blame, so you don't waste your time, check for these symptoms.

A simple test: call another phone and turn on speakerphone. If the sound in the handset is muffled and the speakerphone is clear, the problem is exactly in the top speaker. If the sound is distorted both there and there, it may be the firmware fault (try resetting the sound settings to Settings → Sound Reset → Settings → Sound Reset →).

⚠️ Attention: if the speaker starts wheezing after the phone falls or moisture gets in, cleaning can aggravate the problem.

Method 1: Cleaning with Scotch (for mild contaminants)

This is the most gentle and safe method, and is suitable for regular prevention, removing up to 70% of surface dust and potassium fat deposits without risking damage to the membrane.

You'll need:

• 📏 A piece of paint tape 1-1.5 cm wide (not stationery! it leaves glue).
• 🔍 Loop or phone flashlight for illumination.
• 🧴 Alcohol wipes for degreasing.

Step-by-step:

1. Wipe the area around the speaker with an alcohol towel to remove the fat.
2. Cut a piece of tape and fold it with a sticky side outside the house.
3. Carefully press the tape to the speaker grille and pull it up. Repeat 3-4 times, each time using a new section of tape.
4. Check the results by calling another phone.

Make sure the phone is turned off

Degreasing the surface around the speaker

Use only paint scotch

Don't push too hard.-->

This method is particularly effective for models with wide lattice holes, such as the Redmi 9A or POCO M3. For phones with narrow slits (like the Mi 11 Lite), it is better to combine scotch with other methods.

💡

If you don't have paint tape on hand, you can use the sticky side of the sticker for notes (post-it). It's less aggressive, but it collects dust well, too.

Method 2: Toothbrush + isopropyl alcohol (deep cleaning)

If the tape didn't work, it means the trash got deeper, and in this case, a soft toothbrush and alcohol will help, and this method removes up to 90 percent of the contaminants, but it requires caution.

What do you need?

• 🪥 New toothbrush with soft bristles (preferably children's).
• 🧪 Isopropyl alcohol 70–90% (not vodka!).
• 💨 Compressed air cylinder (optional).

Instructions:

1. Soak the hair with alcohol (do not drink alcohol on your phone!).
2. With careful movements along the speaker's grille (not across!) clean the holes. Don't push, the bristles should only touch the surface.
3. Let the alcohol evaporate (2-3 minutes).
4. If there is a canister with compressed air, short pulses (no more than 1 second) blow the speaker from a distance of 5-7 cm.

⚠️ Warning: Never use cotton swabs, they leave fibers that can get onto the membrane and make the sound worse. Also, avoid hydrogen peroxide, which corrodes the glue that holds the speaker grille.

For dual speaker models (such as the POCO F3 or Xiaomi 12 Pro), repeat the procedure for both holes. After cleaning, check the sound balance in Settings → Sound → Speaker Balance – sometimes it gets lost.

Method 3: Vacuum cleaning (for persistent contaminants)

If the speaker is clogged with fabric fibers (for example, after wearing the phone in your jacket pocket) or fine sand, mechanical methods may not help. USB-vacuumer.

How to do it right:

1. Turn the vacuum cleaner on to the minimum power (or use a nozzle with a narrow nozzle).
2. Hold the phone to the speaker at a distance of 1-2 mm (not close!).
3. Hold for 2-3 seconds, then check the sound.

For better effect, before vacuum cleaning, you can soak the pollution with steam a little.

• 💨 Hold your phone over a cup of hot water (not boiling water!) for 1-2 minutes.
• 🚫 Do not allow condensation to hit the body.
• 🔄 After heating up, immediately apply a vacuum cleaner.

Note: This method is not suitable for phones with a leakproof body (for example, Redmi 7A or POCO C3).

Method 4: Ultrasonic cleaning (advanced method)

This is a little-known, but highly effective way that service centers use, which removes 100 percent of the contaminants, including those that have penetrated the bars, and for home use, an ultrasound bath (which is sold for cleaning jewelry) or even a tooth ultrasound brush is suitable.

Step-by-step:

1. Remove the cover and protective film (if it closes the speaker).
2. Pour distilled water (or alcohol) into the bath so that the liquid level is lower than the speaker by 1-2 mm.
3. Place your phone in the tub with the speaker down (don’t dive completely!).
4. Turn on the ultrasound for 1-2 minutes. Vibration will push the dirt out of the holes.
5. Take out your phone and dry for at least 24 hours in a dry place (silicagel can be used).

⚠️ Note: This method is not suitable for phones with non-removable batteries unless they have official standard protection. IP53 and higher (for example, Xiaomi 13 Pro or Redmi Note 12 Pro)+). For other models, the risk of corrosion is too high.

Alternatively, if you have a toothbrush (like Oral-B), turn it on at the lowest power and hold it to the speaker for 5-10 seconds, and the vibration will help to dislodge debris, but without the risk of fluid.

Method 5: Disassembly of the phone (extreme case)

If neither method worked, it means that the debris has penetrated the speaker's grille or the membrane, and that would require a partial analysis, which is the riskiest way, but sometimes necessary.

What you need:

• 🔧 A set of plastic shoulder blades (metal can scratch the body).
• 🧲 Magnetic screwdriver for screws (usually) T3 or T4).
• 📱 Suction for screens (optional, for models with a removable front panel).
• 🎥 Hair dryer for softening glue (temperature not higher than 60)°C).

The following is the example of Redmi Note 10 Pro:

1. Turn off the phone and remove it. SIM-map.
2. Heat the back end edge with a hair dryer (30–40 seconds).
3. Carefully tuck the lid with a plastic spatula, starting at the corner next to the power button.
4. Unscrew the screws that fix the metal plate over the speaker (usually 3-4 screws).
5. Remove the speaker grille (it can be glued - gently tucked).
6. Clean the speaker membrane with a soft brush or compressed air.
7. Collect the phone in reverse order, checking the density of the fitting parts.

After disassembling, be sure to check the tightness of the case. If the phone becomes worse to hold a charge or overheat, you may have damaged the thermal paste on the processor - in which case you will need to replace it.

Prevention: how to protect the speaker from clogging

It’s better to prevent a problem than deal with its consequences. Here are 5 rules that will prolong the dynamics of your Xiaomi:

• 📱 Use a case with a notch under the speaker. Closed covers (for example, books) accelerate clogging by 2 times.
• 🧴 Clean your phone regularly with a towel, especially after long conversations.
• 🚫 Don’t carry your phone in the back pocket of your pants – it comes into contact with cloth and dust.
• 🔇 Turn off your phone during cleaning (vacuum cleaner, wet cleaning) – fine dust easily penetrates the holes.
• 🛡️ Put a protective film with a cutout under the speaker, which doesn't make the sound worse, but it protects against potassium fat deposits.

For IP53-protected models (such as the Redmi Note 11 Pro+), you can use a hydrophobic coating (sold as a spray) that repels moisture and fat, but you need to apply it carefully without getting on the microphone.

💡

If you talk on the phone often in dusty conditions (for example, on a construction site), use a headset with a microphone. This will reduce the load on the upper speaker by 3-4 times.
