How to clean the speaker on the phone Xiaomi Redmi: from dust to water

Why does the Xiaomi Redmi speaker start wheezing or playing quietly?

Did you notice that the sound in your Xiaomi Redmi has become muted, there are wheezing or distortions? 90% of the time it's because of the clogging of the speaker. Dust, villi from your pocket, fluid leaks — all of this accumulates in the small speaker grid and degrades the sound, and the lower speaker models are particularly vulnerable: Redmi Note 10 Pro, Redmi 9A, POCO X3 and others.

But don't rush to bring your phone to the service! In most cases, you can clean the speaker yourself without disassembling the case and risk losing the warranty. The main thing is to act carefully and use the right tools. In this article, we will analyze 5 proven cleaning methods, from the simplest to the deeper ones, and also tell you what you can not do so as not to damage the speaker membrane.

Before you start, check if the clogging is really the problem, sometimes the quiet sound is due to system settings or membrane damage.

• 🔊 Check the volume in the settings (Settings) → Sound and vibration → Media volume).
• 🎵 Turn on the bass track – if the sound is distorted only at low frequencies, dust is to blame.
• 📱 Restart your phone – sometimes software failures mimic hardware problems.

Method 1: Cleaning the speaker with tape (for dry dust)

This is the most gentle and safe method, which is suitable for removing surface dust and villi. You will need narrow tape (preferably stationery or paint) or sticky tape for cleaning lenses (sold in photo stores).

Algorithm of action:

1. Cut a strip of scotch 3-5 mm wide and 4-5 cm long.
2. Carefully press the sticky side against the speaker grid without pressing.
3. Smooth movement remove the tape - dust and debris will remain on it.
4. Repeat 2-3 times using clean areas of scotch.

⚠️ Warning: Do not use wide tape, it can hook the speaker grid and tear it off. Also avoid adhesive tapes with aggressive glue (such as packaging tape), they leave traces.

This method is effective for the Redmi 8/9/10 series, where the speaker is protected by a metal mesh, and for models with tissue protection (for example, POCO F3), it is better to use other methods.

Method 2: Purging with compressed air (for deep cleaning)

If dust has penetrated deep into the speaker, a can of compressed air (sold in electronics stores or computer accessories) can help, which removes debris from hard-to-reach places without contacting the membrane.

How to properly blow the speaker:

• 🎯 Keep the cylinder vertically at a distance of 5-7 cm from the speaker.
• 💨 Short presses (1-2 seconds) provide air at an angle of 45°.
• ⏹️ Do not hold the jet longer than 3 seconds – it can damage the membrane.
• 🔄 Repeat 2-3 times with breaks of 10 seconds.

⚠️ Warning: Never turn the cylinder upside down, which will result in a release of liquid air that can freeze the speaker membrane. Also avoid too close a distance: pressures greater than 3 bar risk deforming the thin membrane.

Method 3: Cleaning the dynamics with a soft brush (for persistent contaminants)

If the scotch and air didn't work, try a soft brush with natural pile (for example, makeup or watercolours), the main rule is that the pile should be short and hard, so as not to get stuck in the net.

Step-by-step:

1. Dip the brush in isopropyl alcohol (70% and above) or vodka - this will dissolve fat deposits.
2. In light circular movements, walk along the speaker grid without pressing.
3. Let the alcohol evaporate (1-2 minutes) and repeat with a dry brush.
4. Finish with compressed air.

⚠️ Warning: Do not use cotton swabs, they leave fibers that will clog the speaker further. Also avoid toothbrushes, their bristles are too stiff and may scratch the protective net.

Method 4: Removal of fluid from the speaker (if the phone is wet)

If the sound becomes quiet after water hits, you need to act immediately - in the first 30-60 minutes. The liquid oxidizes the contacts of the speaker and can disable it.

Emergency measures:

• 📴 Turn off the phone and remove it. SIM-memory-card.
• 💧 Carefully shake off the drops while holding the phone down speaker.
• 🌬️ Blow the speaker with compressed air (a balloon or a dryer in cold mode).
• 🔥 Place your phone in a silica gel bag (out of a shoe box) for 12 to 24 hours.

⚠️ Warning: Don't dry your phone on a battery or in a microwave! Overheating deforms the speaker membrane. Also don't use rice - it leaves dust and doesn't absorb moisture efficiently.

If the sound didn't recover after drying, the contacts might have oxidized, and then the alcohol cleaning would help.

1. Wet the brush in isopropyl alcohol (90% and above).
2. Gently wet the speaker grid without pressing.
3. Let the alcohol evaporate naturally (do not turn on the phone 1-2 hours).

💡

If the speaker starts to gurgle after the liquid hit, it's a sign that the water is still inside. Immediately repeat the drying with compressed air and silica gel!

Method 5: Deep cleaning with disassembly (for power users)

If all the previous methods didn't work, you'd have to remove the speaker's protective grid, which is a risky way, because you can damage the plume or the membrane, but it gives you access to internal contaminants.

What you need:

• 🔧 Plastic mediator or opener to remove the cover.
• 🔍 Lupus and good lighting.
• 🧴 Isopropyl alcohol and brush.
• 🧲 Magnetic screwdriver (for some models).

⚠️ Note: Disassembly of the phone is not warranty! If your Redmi warranty, you better contact the service center. Also note that in models Redmi Note 11 and newer speaker is often glued to the body - it is easy to tear off if you take carelessly removed.

The following is a step-by-step instruction for the Redmi 9/10 series:

1. Heat the back cover with a hairdryer (temperature 60-70 ° C) for 2-3 minutes - this will soften the glue.
2. Carefully tuck the cover with a plastic mediator, starting at the corner next to the speaker.
3. Disconnect the battery plume (required!), then the speaker plume.
4. Remove the protective grate and clean the membrane with alcohol and brush.
5. Collect the phone in reverse order, making sure all plumes are tightly connected.

💡

Before you assemble, check the tightness of the speaker: turn on the phone and put your finger on the membrane. If you feel the air flow, the sealing gum is damaged and you need to replace it.

What not to do when cleaning the speaker Xiaomi Redmi

Some folk methods can irrevocably ruin the speaker.-5 forbidden:

1. Spin with your mouth. Saliva contains enzymes that corrode the membrane, and your lung pressure is uncontrollable.
2. Use a vacuum cleaner. It creates reverse traction, and it can pull the membrane in and deform it.
3. Brush with toothpicks or needles, and even a slight touch punctures the membrane, and then the speaker starts to wheez.
4. Water the speaker with alcohol or water, and the fluid enters the body and oxidizes the contacts.
5. Dry with a hair dryer in hot mode, and overheating deforms the glue and membrane, which causes the sound to be distorted.
