How to clean the speaker on Xiaomi Redmi Note 8 Pro: safe methods and tips

The sound on your Xiaomi Redmi Note 8 Pro is quieter or wheezing? The reason most often lies in the clogging of the speakers - dust, villi or even small debris penetrate the safety net and worsen the sound quality. Cleaning the speakers in the service center will cost 500-1,500 rubles, but you can cope with the problem yourself if you act carefully.

In this article, we'll look at 5 proven cleaning methods, from simple (with tape or toothpicks) to deeper (with the back cover removed), which tools you'll need, how to avoid damage to the speaker membrane, and what to do if the sound is not restored, and focus on the dynamics of the spoken (top) - it is cleaned differently than the main bottom, due to differences in design.

Before you start, check: Is the problem exactly in the dynamics? Sometimes the quiet sound is associated with settings → Settings → Sound → Media volume or damage to the plume. If after cleaning, there is no improvement, the speaker or audio chip may be faulty.

1. Signs of clogging of speakers: how to know that it is time to clean

The Redmi Note 8 Pro speakers become clogged gradually, and many users don't notice the sound deterioration until it becomes critical.

• 🔊 Muffled sound – music, video or voice are less heard than before, even at maximum volume.
• 🎵 Wheezing and interference – when playing low frequencies (for example, bass) there are extraneous noises.
• 📵 No sound in one speaker – if the Redmi Note 8 Pro is equipped with stereo sound, one of the speakers can completely “silence".
• 🌫️ Visible dirt - in bright light through the speaker grid, clusters of dust or villi are noticeable.

If you notice any of these signs, don't delay cleaning. Ignoring the problem for a long time can damage the speaker membrane, and it's going to have to be changed completely, and it's expensive to repair.

⚠️ Warning: Don't confuse clogging speaker with software glitches! before cleaning, restart your phone and check the sound in safe mode (press the power button). → Safe Mode: If the problem is gone, it's the application, not the hardware.

2 Preparation for cleaning: what will be needed and precautions

To clean the speakers Redmi Note 8 Pro does not need professional tools — enough tools at hand.

Important: Do not use metal objects (needles, knives, paper clips) - they can scratch the membrane of the speaker or mesh, and avoid water and aggressive solvents (acetone, gasoline), which corrode the adhesive bases inside the phone.

⚠️ Warning: If your Redmi Note 8 Pro has been in water or other liquid, cleaning the speakers is useless without first drying.

3. Method 1: Cleaning dynamics with tape (the safest method)

This method is suitable for removing surface dust and villi that do not require disassembling the phone, and can be used prophylactically every 2-3 months, especially if you carry the Redmi Note 8 Pro in your pocket with keys or coins.

Instructions:

1. Cut a small piece of tape (5-7 mm wide, 2-3 cm long).
2. Carefully press the sticky side against the speaker grid without pressing - a light touch is enough.
3. Smoothly pull the scotch up. Repeat 3-4 times, each time using a new piece.
4. For the bottom speaker (near the USB-C connector), use a tape folded in half with the sticky side outwards - it's easier to get to the corners.

This method is effective in removing:

• 🧵 Villus from clothing or fabric.
• 🌫️ Dust accumulated on the surface of the grid.
• 🍃 Small particles (sand, earth) caught in the phone.

If the sound doesn't improve after cleaning the tape, move on to deeper methods, and this method is useless for fatty contamination (for example, if the speaker is stained with cream or cosmetics) - you will need alcohol.

💡

For better results before cleaning the tape slightly blow on the speaker - this will lift dust from the depth, and it will more easily stick to the sticky tape.

Method 2: Toothpick and brush cleaning (for persistent contaminants)

If the tape fails and you can see large debris particles in the dynamics, use a toothpick or soft brush, which requires more care, as there is a risk of damaging the speaker membrane if you press it hard.

Step-by-step:

1. Take a wooden or plastic toothpick (not metal!) and blunt the tip by rubbing it against sandpaper or other rough material.
2. Carefully tuck the edges of the speaker grid and gently scrape it from the center to the edges. Don't push -- the membrane is right under the grid!
3. To remove dust from the cracks, use a brush: run it across the grid in short movements.
4. If the garbage is stuck deep, try to blow the speaker with a can of compressed air (hold the balloon vertically, at a distance of 5-7 cm).

Features of cleaning different speakers:

• 📞 Top speaker (conversational) - it's harder to clean because of the small size. Use a toothpick wrapped in a thin cloth.
• 🔈 Lower speaker (multimedia) - here the grid is larger, you can use a brush with a tougher bristles.

⚠️ Attention: If you've had a toothpick that makes the sound worse (a crack or whistle), you've probably damaged the membrane.

5. Method 3: Deep cleaning with the removal of the back cover (for experienced)

If surface methods don't work, you'll have to disassemble the phone, which is risky -- you can damage the plumes or lose the water protection (if you had one), but it's the only one that can save you if you get too much pollution or fluid.

What you need:

• 🔧 Set of screwdrivers (cross-haul) PH00, flat-footed 1.5 mm).
• 🧲 Screen suction cup (or mediator).
• 🔥 Fryer (for softening glue).
• 🧴 Clay. B-7000 (reverse-assembly).

Step-by-step:

1. Turn off the phone and remove the tray. SIM-map.
2. Heat the hair dryer back cover around the perimeter (temperature 60-70 ° C) for 2-3 minutes - this will soften the glue.
3. Put the lid on with a mediator or suction cup starting at the bottom corner (near the USB-C connector). Move carefully so as not to break the plumes.
4. Unscrew 10 screws that fix the metal plate over the battery (they are of different lengths - remember the location!).
5. Disconnect the battery plume (use a plastic shoulder blade).
6. The speakers are located: the top one is under the screen, glued to the frame; the bottom one is next to the USB-C connector, attached to two screws.

Once the back cover is installed, warm it up with a hair dryer (50°C) and press it for 10-15 minutes to securely fix the adhesive.

1. Connecting the battery plume.

2. Puffing all screws (untamed can close contacts).

3. Integrity of flexible plumes (especially display and power buttons).-->

6. Method 4: Ultrasonic cleaning (for advanced users)

This method is used in service centers, but it can be repeated at home if you have an ultrasound bath (costs from 2000 rubles) and is effective for removing oxidation after getting liquid or deep dust.

Instructions:

1. Remove the speaker from the phone (see section on disassembly).
2. Place it in an ultrasonic bath with distilled water or isopropyl alcohol (70%).
3. Set the frequency of 40 kHz and a time of 2-3 minutes.
4. After cleaning, dry the speaker with a hair dryer (cold air) or leave for 12 hours at room temperature.

7. Method 5: Software Diagnostics Before and After Cleaning

To make sure that the problem is pollution, and not hardware malfunction, test the speakers using an engineering menu or third-party applications.

Method 1: Through the Engineering Menu (without root):

1. Open the Phone app and dial ##4636##.
2. Select the hardware information → Audio tests.
3. Test both speakers in turn, and if one of them doesn't make sound, it's a hardware problem.

Method 2: The Phone Doctor Plus (Play Market) app

• Download and launch the app.
• Go to the Audio section → Loud Speaker Test.
• Compare the volume before and after cleaning.

If after cleaning, the tests show improvement, but the sound is still not perfect, it may be that the speaker is worn out.The average life of the speakers in the Redmi Note 8 Pro is 3-4 years with heavy use.

8.Prevention: How to protect speakers from clogging

To lessen the use of cleaning, follow simple rules:

• 📱 Carry your phone in your own pocket – without keys, coins, or other abrasive items.
• 🧴 Avoid getting creams, hairsprays and other sticky substances on speakers.
• 🌧️ When raining or high humidity, use a splash-proof cover.
• 🔊 Once a month, blow the speakers with a spray of compressed air (keep at a distance of 10 cm).
• 🎧 To listen to music in dusty conditions (construction, repair) use headphones.

If you drop your phone frequently or use it in extreme conditions (dust, dirt, moisture), consider installing a safety net on your speakers. You can order it on AliExpress (search for "mesh speaker protector for Redmi Note 8 Pro").

💡

Even with careful use, the Redmi Note 8 Pro speakers lose up to 30% volume in 2 years due to natural membrane wear. Regular cleaning helps delay replacement by 1-1.5 years.
