How to Clean the Speaker on Xiaomi Redmi Note 8T: Safe Techniques Without Risk for Your Phone

Xiaomi Redmi Note 8T is a popular smartphone with great sound, but over time, the speakers can get clogged with dust, which makes the playback quality worse. If you notice that the sound has become quieter, there are wheezing or distortions, most likely, the problem lies in the pollution. In this article, we will understand how to clean the speaker on the Redmi Note 8T yourself without resorting to expensive repairs.

It's important to understand that speakers in smartphones are delicate components. If you clean them incorrectly, you can damage the membrane or the contacts. So we'll take a closer look at safe methods that don't require you to disassemble the device completely, from simple methods using improvised tools to more advanced techniques, you'll find the right solution for you.

Before you start cleaning, make sure that the problem is really the dynamics. Sometimes the cause of bad sound can be a software failure or damage to the plume. To rule this out, check the sound through the headphones or external speaker. If the sound is normal, then it is the dynamics of the smartphone.

Causes of pollution of speakers in Xiaomi Redmi Note 8T

Smartphone speakers are susceptible to contamination because of their design. In the Redmi Note 8T, speakers are located at the bottom of the case, where most of the dust and debris accumulates.

• 🌪️ Dust and small debris – get through the speaker grille when carrying a phone in your pocket or bag.
• 💦 Moisture and condensate – even a small amount of moisture can leave a plaque on the membrane.
• 🧴 Cosmetic products – creams, lotions and even sweat can clog the grille.
• 📱 Long-term use – over time, any speakers lose quality due to natural wear and tear.

Pollution is especially severe if you use your phone frequently in dusty spaces or outdoors, for example, building dust or sand can clog the speaker's grille in a matter of days, and in such cases cleaning is required more often than with normal use.

Also, the Redmi Note 8T has two speakers: the main speaker (bottom) and the conversation speaker (top), and the main speaker suffers more often, since it is located next to the charging connector, where more debris gets into.

Preparation for cleaning: what you will need

Before cleaning the speaker on the Xiaomi Redmi Note 8T, prepare the necessary tools. Do not use sharp objects such as needles or toothpicks - they can damage the membrane.

• 🧹 Soft brush - a makeup brush or a clean toothbrush with soft bristles is suitable.
• 💨 A container with compressed air - you can buy in the electronics store.
• 🧲 Scotch or sticky tape – to remove large particles of debris.
• 🔦 Lights to better consider pollution.
• 🧴 Alcohol wipes - to clean the speaker grille.

If you don't have a compressed air can, you can use a dryer at minimum power, but be careful: too hot air can damage the plastic parts of the case, and don't direct the air flow too close to the speaker.

Before starting work, be sure to turn off the phone and remove it. SIM-This will prevent accidental switching on of the device and damage to the contacts, and also make sure that the hands are dry and clean.

Method 1: Cleaning dynamics with compressed air

One of the safest ways to do this is to use compressed air, which allows you to remove dust and small debris without touching the speaker.

1. Take a spray of compressed air and hold it vertically.
2. Direct the tube of the can at an angle of 45 degrees to the speaker grille.
3. With short presses (1-2 seconds) blow the speaker. Do not hold the jet of air for too long so as not to damage the membrane.
4. Repeat the procedure 2-3 times, changing the angle of inclination.

If you don't have a can, you can use a dryer. Set it to cold air and minimum power. Keep the dryer 10-15 cm away from the speaker and blow through the grille with short pulses.

After cleaning, check the sound. If there's any wheezing or distortion, maybe the pollution is too strong and you need a deeper cleaning, in which case you move on to the next method.

Method 2: Brushing with a brush or toothbrush

If the compressed air didn't work, you can try to clean the speaker with a soft brush, which is more effective at removing sticky contaminants like cream or sweat. It's important to use a soft bristles brush to avoid scratching the grille.

Algorithm of action:

1. Carefully run the brush on the speaker grille in one direction.
2. Don’t push too hard – light movements are enough.
3. After cleaning, blow the speaker with compressed air to remove the remaining dust.

If you don't have a brush, you can use a new toothbrush with soft bristles, pre-treat it with alcohol to remove any impurities, and the movements should be smooth and directed from the center of the speaker to the edges.

This technique is well suited to removing tissue fibers or small villi that are often clogged into the grille, but it is less effective against dust that has penetrated deeply into the speaker.

💡

If the brush doesn't work, try to moisten it slightly in alcohol. This will help remove fatty contamination, but do not overdo it - moisture should not get inside the speaker.

Method 3: Use of Scotch or Sticky Tape

Scotch can be used to remove large debris particles, such as sand or small pebbles, and this is especially useful if you've dropped your phone recently or been in a dusty place.

1. Cut a small piece of scotch (about 2-3 cm).
2. Carefully apply the sticky side to the speaker grille.
3. Pull it down a little and pull it off abruptly. Repeat it 2-3 times.

This is a way to remove particles that are not blown away by air or brushed, but it's not good for deep cleaning -- the tape doesn't get inside the speaker, and be careful, if there are greasy spots on the grille, the tape can leave a trace.

If the sound hasn't improved after cleaning with tape, try combining this method with previous ones, such as using tape to remove large debris first, and then blowing the speaker with compressed air.

Method 4: Partially disassembled deep cleaning (for power users)

If previous methods didn’t work, you may need a partial disassembly of the phone. In the Xiaomi Redmi Note 8T, the speaker is attached to the motherboard, and to completely clean it, you need to remove the back cover.

You'll need:

• 🔧 Plastic mediator or spatula for disassembly.
• 🔩 Screwdriver with nozzle T3 or T4 (depending on the screws).
• 🧲 Screen removal suction cup (optional).
• 🔍 Loop for detail inspection.

Step-by-step:

1. Turn off the phone and remove the tray for SIM-map.
2. Heat the back cover with a hairdryer (temperature not higher than 60°C) to soften the glue.
3. Carefully tuck the lid with a plastic mediator, starting at the corner next to the charging connector.
4. Unscrew the screws holding the metal plate over the speaker.
5. Remove the plate and gently clean the speaker with a brush or compressed air.

After cleaning, put the phone back together. Make sure all screws are tightly swirled, but don't pull them over. If the phone doesn't turn on after assembly, check the plumes are connected.

💡

Partial disassembly of the Redmi Note 8T requires caution. If you are not sure of your skills, you should contact the service center. Incorrect assembly can damage the plumes or detach the screen.

What not to do when cleaning the speakers

Some actions can irrevocably damage speakers or other components of a smartphone, which is strictly forbidden:

• 🚫 Use sharp objects – needles, toothpicks or knives can pierce the membrane.
• 🚫 Blow the speaker with your mouth – saliva contains acids that can damage contacts.
• 🚫 Use wet wipes – moisture can cause corrosion.
• 🚫 Use harsh chemicals – acetone, gasoline or solvents destroy plastic.

Also, don't try to disassemble the phone without the tools you need, for example, using a metal screwdriver instead of a plastic mediator can leave scratches on the body or damage the plumes.

⚠️ Warning: If after cleaning the speaker starts to make extraneous sounds (squeaking, crackling), immediately stop using the phone. This may indicate damage to the membrane.

Comparison of cleaning methods of speakers

To choose the most suitable method, compare their effectiveness and risks:

For most users, the best solution is a combination of compressed air and brush. If the pollution is severe, but you do not want to risk dismantling, contact the service center. The cost of cleaning the speaker in the Xiaomi Redmi Note 8T usually does not exceed 500-1000 rubles, which is cheaper than repairing after a failed self-cleaning.
