How to clean the Xiaomi speaker yourself 8T: from dust to complex pollution

Xiaomi speakers 8T And they lose their sound quality over time because of dust, pile, or even moisture, and if you notice that the sound has become muted, with wheezing or distortion at low frequencies, the problem is probably the contamination of the acoustic system. In this article, we will analyze 5 effective cleaning methods, from simple (using household products) to deep cleaning with disassembly of the case.

It is important to understand: Xiaomi 8T It has two speakers, the main one (bottom one for music and calls) and the conversational one (top one for voice calls), and the cleaning methods differ due to their different layout and design. We will describe in detail the nuances for each case, as well as give recommendations for pollution prevention so that the problem does not recur.

If the sound is not restored after cleaning, the reason may lie in damage to the speaker membrane or detachment of contacts. In such cases, professional repair will be required. But in 80% of cases, the pollution is eliminated on its own - the main thing is to follow the instructions and not use aggressive methods (for example, purging with compressed air under high pressure).

Signs of pollution of speakers: when it's time to clean

Before you start cleaning, make sure that the problem is the contamination, not a software failure or hardware breakdown.

• 🔊 Muffled sound – the music and voice of the interlocutor are heard, but as if “from under the blanket».
• 🎵 Distortions at low frequencies – bass notes “drum” or disappear completely.
• 📞 Wheezing during calls - especially noticeable when on speakerphone.
• 🌫️ The visible dust in the lattice is a speaker - if you shine a flashlight, you can see the accumulation of dirt.
• 💧 Traces of moisture – after water hits, the sound can become “silky” or intermittent.

If one of the points matches, it's time to act, but first check the phone's audio settings: it may be a problem in activated Do Not Disturb mode or misplaced uniform settings (EQ). To do this, go to the Settings. → Sound and vibration → Sound quality and reset parameters to factory.

⚠️ Warning: If the sound is completely lost (the speaker is not making any sounds), do not try to clean it yourself. Most likely, the contact has gone away or the coil has burned - here you need a diagnosis at the service center.

Preparation for cleaning: what will be needed

For safe cleaning of Xiaomi speakers 8T Prepare the following tools and materials:

What NOT to use:

• 🚫 Needles, pins, metal objects – will damage the protective net.
• 🚫 Wet wipes on an alcohol basis - can leave divorces.
• 🚫 Vacuum cleaner – too strong traction can tear the speaker membrane.
• 🚫 Acetone, gasoline, solvents – will destroy plastic and glue.

If you are planning a deep cleaning with disassembly, additionally prepare:

• 🔧 Set of screwdrivers (cross, flat, torks) T3-T5).
• 🧲 Plastic mediator or blade for opening the body.
• 📦 Container for screws (so as not to lose).

💡

Before cleaning, back up your phone data. In rare cases, when disassembling, you may experience a reset or damage to the plumes.

Method 1: Dry cleaning without disassembly (for mild contaminants)

This method is suitable if the contamination is minor (dust, pile) and does not require deep intervention. 2-3 month.

1. Turn off the phone and get it out. SIM-card/memory card (if any) this will prevent accidental switching on during cleaning.
2. Take a soft brush and gently run it through the grille of the speaker (both the lower and the upper), and move lightly, without pressure, from the center to the edges.
3. To remove the pile, use paint scotch: cut a small piece (1-2 And you're going to have to put your sticky side against the bars and pull it off. 2-3 once.
4. If there are large particles stuck between the lattice holes, put them in a toothpick, pre-wetting the tip of the lattice in isopropyl alcohol. Don't push, just pick up dirt.
5. Finish the procedure with compressed air. Hold the sprayer vertically at a distance. 5-7 It's a speaker, short presses (1-2 seconds) remove the dust residue.

After cleaning, turn on your phone and check the sound. If you have any wheezing, move on to the next method.

Method 2: Wet cleaning using alcohol

If dry cleaning didn't work, and if you can see sticky contaminants on the speaker grille (like traces from drinks or cosmetics), you'll need wet treatment. It's important not to overdo it with the liquid!

You will need to:

• 🧴 Isopropyl alcohol (70% or higher).
• 🧻 Cotton swabs (better with a plastic rod).
• 🧼 Cotton disc.

Step-by-step:

1. Soak the cotton swab in alcohol and squeeze the excess liquid on the edge of the container. The wand should be wet, but not dripping!
2. Gently wipe the speaker grille with circular motions without pressing. For the bottom speaker, it is more convenient to put the phone down with the screen.
3. For hard-to-reach places, use a toothpick wrapped in a thin layer of cotton soaked in alcohol.
4. After processing, dry the speaker 10-15 minutes at room temperature (do not use a hair dryer!).
5. Blow the grille with compressed air to remove any moisture residue.

⚠️ Warning: Never pour alcohol directly on the speaker - liquid can leak in and damage the membrane or contacts. Always apply alcohol to the cotton swab instead of the phone!

If you've got a wet cleaning, and it's worse (cod or no sound), it means the alcohol has gotten inside the speaker, so don't turn on the phone for 24 hours, let it dry completely. If the problem persists, call the service.

Method 3: Deep cleaning with partial disassembly of the body

This method requires experience with electronics and is suitable if previous methods have failed, and we will consider partial disassembly without full removal of the motherboard, which reduces the risks.

What you'll need:

• 🔧 Set of screwdrivers (cross-haul) PH00, flat-footed 1.5 mm).
• 🧲 Plastic mediator or shoulder blade.
• 📦 Magnetic screw mat.
• 🔍 Lupa (optional, to inspect contacts).

Step-by-step process:

1. Turn off the phone and remove the tray for SIM-Place the device on a soft surface (e.g. a towel).
2. Heat the back cover with a hair dryer (temperature) 50-60°C) during 1-2 It'll soften the glue that holds the lid.
3. Insert a plastic mediator into the gap between the lid and the body (start at the bottom corner) and gently slap it around the perimeter with the mediator to disconnect the latches.
4. Take the lid off. Be careful, it's got a fingerprint scanner plume attached to it (if you have one in your model).
5. Unscrew the 4 screws that attach the metal plate over the speaker (marked with the red dots in the photo below).
6. Now you'll see the speaker itself. Gently blow it through with compressed air, then wipe it with a cotton swab dipped in alcohol. Pay attention to the contacts -- they should be clean and shiny.
7. Put the phone back together, make sure all the latches on the lid are in place.

Once assembled, turn on the phone and check the sound. If the wheezing is still there, the problem may be the damage to the membrane - you will need to change the speaker.

💡

Deep cleaning with disassembly gives you better results, but increases the risk of damage to the phone. If you are not sure of your skills, contact the service center.

Method 4: Ultrasound cleaning (for power users)

Ultrasonic bath is one of the most effective ways to clean speakers, but it requires a complete dismantling of the part.

• 🔊 The speaker is heavily contaminated with sticky substances (for example, after getting soda).
• 🛠️ You have tried other methods, but the result is unsatisfactory.
• 🔧 You have experience disassembling phones and access to an ultrasonic bath.

How it works: Ultrasonic waves create microscopic bubbles in the liquid that knock dirt out of the speaker's hardest-to-reach places. However, improper use can damage the membrane.

Instructions:

1. Remove the speaker from the phone (see method) 3, stepping-step 1-5). Disconnect it from the plume, carefully poke the connector with a plastic blade.
2. Place the speaker in an ultrasonic bath with distilled water or isopropyl alcohol (70%) and the liquid temperature is no higher than 40.°C.
3. Set the timer on 1-2 A longer exposure can deform the membrane.
4. After cleaning, remove the speaker and dry it for 24 hours in a dry, warm place (for example, on a battery, but not in direct sunlight).
5. Set the speaker back, collect the phone and check the sound.

⚠️ Warning: Do not use ordinary tap water for ultrasonic cleaning - mineral deposits can remain on contacts and worsen the sound!

Method 5: Professional cleaning in the service

If you are not sure of your abilities or previous methods did not help, it is better to contact the Xiaomi service center or a proven workshop.

• 🔍 Diagnosis of dynamics for mechanical damage.
• 🛠️ Complete disassembly of the phone with checking contacts and plumes.
• 🧼 Ultrasonic or chemical cleaning (depending on the type of contamination).
• 🔧 Replacement of the speaker (if recovery is not possible).
• 📋 Sound testing after repair.

Cost of service: in official Xiaomi services cleaning dynamics costs in 800-1500 ruble, replacement - from 1500 before 2500 In informal workshops, prices may be lower, but the risk of using non-original spare parts is higher.

How to choose a service:

• 📍 Prefer official Xiaomi centers – they have original parts and warranty for work.
• 📄 Check the reviews about the workshop on Yandex.Maps or 2GIS.
• 💬 Check if you have a warranty for repairs (at least 3 months).
• 🔧 Ask if they use an ultrasound bath to clean – this is a sign of a professional approach.

If you decide to contact the service, do not immediately say that you tried to clean the speaker yourself - this may deprive you of warranty (if the phone is still in warranty service), describe the symptoms ("wheezing in the dynamics", "muffled sound") and ask for a diagnosis.

Pollution prevention: how to keep the speakers clean
