How to Clean the Speaker on Xiaomi Phone Yourself: Safe Ways and Errors

Speakers in Xiaomi smartphones are one of the most vulnerable places: dust, moisture and even ordinary dirt eventually clog the grille, worsening the sound quality. If your Redmi Note 12 or POCO X5 began to wheez, sound quieter or even “drum”, do not rush to carry it into the service. In 80% of cases, the problem can be solved by yourself – without disassembling the case and the risk of damaging the microphone or plume.

But there are nuances: improper cleaning can permanently disable the speaker or deprive you of warranties (if the phone is new).In this article, only proven methods that use the masters of service centers, and a list of dangerous mistakes to avoid. We will discuss how to clean the speaker on Xiaomi with improvised means, when to use alcohol and when only dry brush.

Signs of a clogged speaker: when you need to clean

Before you start, make sure that the problem is pollution. The symptoms of a clogged speaker on Xiaomi are often confused with software failures or hardware breakdowns.

• 🔊 The sound became quieter, even at maximum volume (especially noticeable when listening to music or while calling).
• 🎵 Wheezing or distortions at low frequencies (for example, when playing bass) appeared).
• 💧 After moisture is ingested, the speaker “bubbles” or is completely silent (this can be both pollution and corrosion of contacts).
• 📱 When talking, the interlocutor complains that he does not hear your voice well - this may indicate a clogged microphone, which is often cleaned along with the speaker.

If at least one of these symptoms is present, try to diagnose the problem speaker with a test:

1. Open the Phone app and dial ##4636##.
2. In the menu, select Equipment Testing → Audio.
3. Check Speaker (main speaker) and Earpiece (conversational speaker) alternately.

If the sound is clean in the test, but the problems remain in real use, it is the fault of the software (for example, the equalizer settings were lost). If the distortion persists, it is time to clean.

What you need to clean: tools and materials

Xiaomi doesn’t need professional tools to clean its speakers safely — just enough at home — and the rule of thumb is no moisture (unless you use 90%+ isopropyl alcohol for spotting).

⚠️ Warning: Never use metal objects (needles, knives), cotton swabs (fibres remain inside), or household chemicals (e.g. glass cleaning fluid) that can scratch the speaker's membrane or leave chemical traces that erode the contacts over time.

Make sure your hands are dry and clean.

Step-by-step: how to clean the speaker on Xiaomi without disassembly

If you're under warranty or you're not sure about your skills, start with an outdoor cleaning, 90 percent of the time, enough to get the sound back to normal.

Step 1: Dry cleaning of the grille

On most Xiaomi models (e.g. Redmi 10 or POCO F4), the speakers are:

• 📍 Lower speaker next to the connector USB-C.
• 📍 Upper (conversational) - above the screen, under the bar.

Carefully swipe the lattice along (not across!) the line of holes, then wrap the toothpick in a thin cloth (like a microfiber) and walk through each hole. Don't push -- the membrane is thin and can break!

💡

If the dirt is sticky (like sweat), put a piece of tape on the grille with the sticky side down, press it slightly and pull it off abruptly. Repeat 2-3 times.

Step 2: Remove moisture (if the speaker "bursts")

If your phone has been in the rain or fallen into the water, don't dry it with a hair dryer right away, it can drive the moisture deeper.

1. Turn off the device and do not turn on at least 12 hours.
2. Place your phone in a bag of raw rice (it absorbs moisture) or use silica gel (from shoe boxes).
3. Turn on and check the sound in a day, and if the wheezing is still there, dry it again for another 12 hours.

⚠️ Attention: If after drying the speaker did not work, do not try to disassemble the phone - it may be corrosion of contacts.

Step 3: Purge (for persistent dirt)

If the dust is too deep, you can use a compressed air canister (sold in electronics stores). Hold the balloon vertically, 10-15 cm from the grille, and with short presses (no more than 1 second) blow the holes. Don't flip the balloon - this can lead to the release of liquid!

Cleaning dynamics with removal of grilles: for experienced users

If the outdoor cleaning didn't work and the phone wasn't warranty-free, you can try removing the protective grille. It's a risky method, but it gives you access to the speaker membrane, and it's only suitable for removable grille models (like the Redmi Note 9 Pro or Mi 10T).

You'll need:

• 🔧 Plastic mediator or spatula for smartphones.
• 🧲 Magnetic screwdriver (for some models).
• 🔍 Loupa and bright flashlight.

Algorithm of action:

1. Turn off your phone and remove the back cover (if it's removable). On adhesive models (like the Xiaomi 13), it's harder to do that -- you'll need a hair dryer and suction cups.
2. Find the speaker, usually with 2-3 screws attached, and unscrew them carefully and unplug the plume (if you have one).
3. Take the bars off. You'll see a membrane underneath -- don't touch it! Remove the dirt with a brush or tape.
4. If the contacts have oxidation, wipe them with a cotton swab soaked in isopropyl alcohol (do not drip alcohol directly on the board!).
5. Collect the phone in reverse order and check the sound.

⚠️ Warning: On waterproof models (e.g. Xiaomi 12 Pro), removing the grille violates the tightness. IP53.

💡

If the sound hasn't recovered after cleaning, the problem could be a damaged membrane or plume, in which case only a replacement speaker will help.

Frequent Mistakes: What Can Kill a Speaker Forever

Even experienced users sometimes make mistakes that lead to irreversible failure.

• 🚫 Use sharp objects (needles, knives, paper clips) - they pierce the membrane.
• 🚫 Vacuuming the speaker creates static electricity that can damage the chips.
• 🚫 Pour alcohol or water directly onto the grille - the liquid will get inside and cause corrosion.
• 🚫 Cleaning a phone on is a risk of short circuit.
• 🚫 Use force when removing the grille – on Xiaomi it is often attached to latches that are easy to break.

Another common mistake is to ignore the sound test after cleaning. Always check the speaker at different frequencies (e.g. play a track with bass and high notes), if the wheezing is left on some frequencies but has disappeared on others, the problem is in the membrane, not the pollution.

Preventive: How to protect Xiaomi speakers from pollution

It’s better to prevent a problem than deal with its consequences. Here are some simple rules that will prolong the life of your Xiaomi speakers:

• 🛡️ Use a case with speaker protection (for example, with raised edges around the grille).
• 🚿 Avoid getting moisture, even if the phone has protection. IP53, It will not save you from prolonged exposure to water.
• 🧹 Clean the connector regularly USB-C — The dirt from there often migrates to the lower dynamics.
• 🎧 Less often use maximum volume - this reduces the load on the membrane and reduces the risk of damage to it.

If you are often in dusty conditions (for example, on a construction site or on a hike), once a month blow the speaker grille with compressed air. This will take 2 minutes, but save time on deep cleaning.

💡

Keep your phone in a bag or pocket where there are no direct sources of dust (such as chalk or cement), and small particles enter the lattice and cement to form a dense layer of dirt.
