How to clean the speaker on the Redmi Note 8 Pro: from dust to serious blockages

Speakers in the Xiaomi Redmi Note 8 Pro get clogged with dust, pocket villi or dirt particles over time, leading to muted sound, wheezing or the complete disappearance of basses. Especially vulnerable is the bottom speaker - its grid has small holes that quickly clog. If you notice that the sound has become quieter, distortions appear or the phone "bursts" when playing music, it's time to clean up.

In this article, we’ll look at 5 proven ways to clean speakers, from simple (with tape or toothpicking) to deep cleaning with disassembly. You’ll learn which tools are safe for the Redmi Note 8 Pro and which can damage the membrane or mesh. We’ll also explain why using wet wipes or alcohol is strictly forbidden for the speakers of this model – this can lead to corrosion of contacts inside the case.

Signs of a clogged speaker: when it's time to clean

Sound deterioration is not always due to pollution, sometimes it's software failures or membrane damage, and check for these symptoms before you clean up.

• 🔊 Muffled sound – bass frequencies disappear, the voice of the interlocutor is heard as if “from a barrel».
• 🎵 Wheezing and crackling when playing music or video, especially at high volume.
• 💧 «Gurgling" - the sound as if passes through the water (often happens after moisture hits).
• 📵 Complete absence of sound in one of the speakers (top or bottom), although in the settings the volume is at maximum.

If at least one of these signs appears, first try the software diagnosis:

1. Restart your phone – sometimes the sound is lost due to a temporary failure.
2. Check the settings: go to Settings → Sound and Vibration → Media Volume and make sure the slider is not at zero.
3. Test the speakers through the engineering menu: dial ##4636##, select Hardware testing → Audio and run each speaker test individually.

⚠️ Warning: If the sound is not restored after the software check, and the speaker is making a metal grind or squeak, this may indicate damage to the membrane.

Method 1: Scotch cleaning (the safest method)

This method is suitable for removing surface dust and fine debris from the speaker grid, and its advantage is zero risk of damage to the membrane or internal components.

• 📏 Stationery tape (preferably narrow, 1-1.5 cm wide) or paint tape.
• 🔦 Flashlight (for lighting the speaker holes).
• 🧴 Alcohol wipes (to clean the case around the speaker, but not the mesh itself!).

Step-by-step:

1. Turn off your phone to avoid accidentally pressing buttons.
2. Cut a piece of tape length of 5-7 cm fold it sticky side out, "loop".
3. Carefully press the tape to the speaker grid and pull it up. Repeat 3-4 times, using a new piece each time.
4. Check if there are any scotch particles left on the grid - remove them with a dry toothpick if necessary.

This method is effective in removing:

• 🌫️ Dust and villi.
• 🍃 Small particles of dirt (sand, earth).
• 🕸️ Webs (if the phone was lying for a long time without using).

⚠️ Warning: Do not use duct tape for packaging – its glue can leave traces on the case of the Redmi Note 8 Pro and damage the oleophobic screen coating if accidentally touched.

Method 2: Toothpick or soft brush for deep cleaning

If the tape didn't work, and you can see the particles stuck in the speaker's openings, you can use a toothpick or a special brush, which is a riskier method, because there is a chance of damaging the mesh or membrane if you move carelessly.

What you need:

• 🪥 Wooden toothpick (not metallic!).
• 🖌️ Soft art brush (synthetic, size 0-2).
• 🔍 Lupa (optional, for accuracy).

How to clean:

1. Carefully run the toothpick parallel to the net, without pressing. The movement should be in the direction of the holes, not across.
2. For hard-to-reach areas, use a brush - brush the dust from the center of the speaker to the edges.
3. After cleaning, blow the speaker with dry air (you can use a can of compressed air for equipment, keeping it at a distance of 10-15 cm).

⚠️ Warning: Do not use needles, pins or metal objects under any circumstances - they can puncture the membrane of the Redmi Note 8 Pro speaker, which will lead to irreversible breakage. Also avoid cotton swabs: their pile can stick in the holes of the mesh.

💡

If you don't have a brush at hand, you can use a clean toothbrush with soft bristles, rinse it in soapy water and dry it thoroughly in cold mode.

Method 3: Vacuum cleaner or compressed air canister

To remove dust from the deep layers of the speaker will suit vacuum cleaner with a narrow nozzle or a can of compressed air (for example, to clean the keyboard), this method is effective when clogging occurred inside the case, rather than on the surface of the mesh.

How to use it correctly:

• 🌀 Vacuum: Set minimum suction power. Keep the nozzle 0.5-1 cm away from the speaker without touching the mesh. Turn on the vacuum cleaner for 2-3 seconds.
• 💨 Pressure air canister: Hold it vertically, 10-15 cm away, blow the speaker with short presses (0.5-1 seconds!

Warnings:

• Do not use a household hair dryer – hot air can deform plastic body parts.
• Don’t direct the jet of air at an angle – this can drive dust deeper into the speaker.
• After cleaning, check the sound – if the wheezing is left, repeat the procedure or proceed to the next method.

Method 4: Disassembling the phone for deep cleaning (for experienced)

If all previous methods did not help, and the speaker is so crowded that there is almost no sound, you will have to disassemble the Redmi Note 8 Pro. This method is risky - you can damage the plumes, disconnect the contacts or break the tightness of the case. Do not start disassembling if you do not have experience with electronics!

What you need:

• 🔧 Set of screwdrivers (cross-haired) PH00, 1.5 mm flat, plastic mediator).
• 🧲 Screen removal suction cup (optional).
• 📸 Camera (to photograph the location of the plumes).
• 🧴 Isopropyl alcohol (90%+) and a squirrel-free napkin.

Step-by-step:

1. Turn off the phone and remove it. SIM-memory-card.
2. Heat the back cover with a hair dryer (60–70°C) for 1-2 minutes to soften the glue.
3. Carefully tuck the cover with a plastic mediator, starting at the bottom corner (where the speaker is located).
4. Disconnect the battery plume, then unscrew the screws holding the speaker.
5. Remove the speaker and clean the mesh on both sides with a dry brush. If you have a lot of pollution, use alcohol, but only for metal parts - don't touch the membrane!
6. Collect the phone in reverse order, making sure all plumes are tightly connected.

⚠️ Note: When disassembling the Redmi Note 8 Pro, there is a risk of damaging the hydrophobic pads that protect the phone from moisture. If after assembly you notice that the phone is no longer water resistant (for example, condensate under the screen), contact the service to replace the pads.

💡

If you are not sure about your skills, it is better to contact the service center.The cost of cleaning the speaker in the official centers of Xiaomi is 800-1500 rubles, which is cheaper than repairing after a failed disassembly.

Method 5: Ultrasonic Bath (Extreme Method)

This method is only suitable for removable speakers (for example, if you have already disassembled the phone) and requires special equipment. Ultrasonic bath removes even microscopic particles of dirt, but if used improperly can destroy the membrane.

How to clean up:

1. Remove the speaker from the phone (see the instructions in Method 4).
2. Place it in an ultrasonic bath with distilled water or isopropyl alcohol (no higher than 70%).
3. Set the temperature of 30-40 ° C and the time of 10-15 seconds.
4. After cleaning, dry the speaker for 24 hours in a dry place (you can use silica gel to speed up the process).

Warnings:

• Do not use regular water – it contains minerals that can settle on contacts.
• Do not dry the speaker with a hair dryer or on a battery - this deforms the membrane.
• After drying, check the resistance of the speaker with a multimeter (should be 4-8 ohms). If the readings are very different, the speaker is damaged.

What not to do when cleaning the speakers

Some “folk” methods can irrevocably spoil the speakers of the Redmi Note 8 Pro.

• 🚫 Blow the speaker with your mouth. Saliva contains enzymes that corrode metal parts.
• 🚫 Use wet wipes or alcohol to wipe the net, and the liquid enters and oxidizes the contacts.
• 🚫 Clean the speaker with a needle or a toothpick at an angle.
• 🚫 Use detergents (soap, shampoo) and they leave a film that attracts dust.
• 🚫 Disassemble the phone without turning off the battery!

Also avoid these mistakes:

• Do not clean the speakers when on – vibration from the sound can drive the dust deeper.
• Do not use the vacuum cleaner at maximum power - this can tear off the membrane.
• Do not dry your phone in rice after moisture is injected - rice particles will clog the speaker even more.
