How to Clean the Speaker on Xiaomi Phone Without Disassembling: A Complete Guide to Auditory Speaker

The hearing aid on Xiaomi smartphones is one of the most vulnerable places: over time, it gets clogged with dust, villi from pockets or skin particles, which leads to muffled sound, wheezing or complete disappearance of the interlocutor’s voice. Many users mistakenly think that it is necessary to disassemble the phone or contact a service center to clean, but this is not the case. 90% of pollution can be eliminated independently without the risk of damaging the speaker’s membrane or losing the warranty.

In this article, we will discuss 5 proven cleaning methods that are suitable for all Xiaomi models (from Redmi Note 10 to Xiaomi 13 Ultra), as well as explain what mistakes users most often make. You will learn how to determine the type of pollution, what tools to use (and what to avoid!), and how to prevent re-clogging.

Signs of a clogged speaker: how to know that it is time to clean

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

• 🔊 Muffled sound during a conversation - the voice of the interlocutor is heard, but as if "from a barrel".
• 🎵 Wheezing or crackling when playing music through a speaker (even at minimum volume).
• 📞 Complete absence of sound in the speaker while the microphone is working (the interlocutor hears you, and you do not).
• 🌫️ Visible dirt in the speaker holes (dust, pile, cosmetic particles).

If the sound is lost periodically (i.e., it is not), the problem may be in the contacts of the plume — here cleaning will not help, you need repairs. Check this out simply: slightly press your finger on the speaker area during the call. If the sound appears, the contacts are to blame, if not — clogging.

⚠️ Warning: Do not confuse a clogged speaker with a switched-off sound in the settings. Before cleaning, check: Speaker Volume in Settings → Sound. Do not disturb mode or meet profile. Headphones in the connector (even if they are not physically present, the phone may "think" they are connected).

What not to use for cleaning: a blacklist of methods

The Internet is full of "advisers" who recommend cleaning speakers with needles, toothpicks or compressed air, most of which are dangerous and can lead to:

• 💥 Puncture of the membrane (even a soft toothpick with an awkward movement will pierce the speaker).
• 🌪️ Driven deeper dirt (compressed air blows dust all over the body).
• 🔥 Short circuit (wet wipes or alcohol can leak inside).

Absolutely forbidden:

The only exception: if the speaker got a liquid (coffee, water), you can gently wet it with a dry cotton swab, but not deeper than 1 mm. After that, the phone needs to be turned off and dried in rice or silica gel for 12+ hours.

Method 1: Cleaning with tape or sticky tape (for surface dirt)

It is the safest and most efficient method for removing dust, pile and fine particles, suitable for Xiaomi Redmi, POCO and flagship models.

• 📏 Scotch or tape (width) 1-2 See, better matte).
• 🔍 Lupa (optional, for accuracy).
• 💡 Good lighting (phone flashlight or table lamp).

Step-by-step:

1. Cut a piece of scotch 3-4 cm long.
2. Then, put it on the outside (to make a sleeve).
3. Carefully press the tape to the speaker holes and pull up. Repeat 3-4 times.
4. For depressions, use narrow strips (with a width of 2-3 mm).

This method removes up to 70% of the contaminants the first time, so if the dirt is left, repeat the procedure or move on to the next method.

Turn off the phone (optional, but recommended)

Wipe the body around the speaker with a dry wipe.

Use only matte scotch (glossy leaves glue)

Don't push the speaker, just a light touch.

Method 2: Soft brush + vacuum cleaner (for deep cleaning)

If the tape didn't work, it means the dirt got deeper, and this is where the combination of an art brush (for example, for watercolor) and a vacuum cleaner at minimum power, why a brush? Its pile is soft enough not to damage the net, but hard enough to knock out the dust.

Algorithm of action:

1. Turn the vacuum cleaner on the lowest power and hold the tube at a distance of 3-5 cm from the speaker.
2. Carefully tap the brush on the speaker holes (do not press!).
3. The dust will fly out and be drawn in by the vacuum cleaner. Repeat it 2-3 times.

For dual-speaker models (such as the Xiaomi 12 Pro or Redmi K50), clean both holes alternately. If the vacuum cleaner is too powerful, use a narrow nozzle nozzle nozzle or cover it with gauze.

⚠️ Warning: Never use a vacuum cleaner without a brush - a strong airflow can damage the membrane or drive dirt into the microphone!

Method 3: Toothbrush + speaker at full volume (vibration method)

This is a technique that works for deaf blockages when there's a sound, but it's very quiet, and it's based on vibration, where the speaker at maximum volume creates vibrations that help to knock out dirt, and the brush catches it.

Instructions:

1. Turn on music with deep bass on your phone (for example, a 50Hz test signal).
2. Set the volume to maximum.
3. Bring a dry toothbrush (with soft bristles!) to the speaker and gently bring it along the holes.
4. Repeat 2-3 times, changing the angle of the brush.

For Xiaomi with stereo speakers (like POCO F4), clean both speakers at the same time. If the sound gets cleaner, the method worked. If not, move on to the next method.

💡

To enhance the effect, you can use the Sound Test app (available in the Play Market) to generate the frequencies that best knock dirt out of the speakers, select a 100-200 Hz frequency and hold the phone down over a soft surface (like a carpet).

Method 4: Special tools: a brush for cleaning cameras and a sticky gel

If you are willing to spend 200-500 rubles on professional accessories, buy:

• 🖌️ Camera brush (e.g. Xiaomi Cleaning Brush – suitable for speakers).
• 🧴 Sticky gel for cleaning (such as Whoosh! Screen Shine).

How to use a brush:

1. Blow off large dust particles (you can mouth, but not by much!).
2. Carefully brush along the speaker holes (not across!).
3. Use rotational motions for the corners.

How to use the gel:

1. Apply a small piece of gel to the speaker.
2. Wait 10 seconds, he'll pull in the dirt.
3. Carefully remove the gel along with the contaminants.

These tools remove up to 95% of contaminants and are safe for the membrane. The main thing is not to use the gel more than 1 time a month, so as not to leave sticky marks.

Method 5: Software cleaning (to remove dust from software)

Sometimes the problem is not physical dirt, but software settings, for example, after the MIUI update, the sound may be drowned out due to a malfunction in the equalizer.

Steps to reset the sound settings:

1. Go to Settings → Sound → Radiator.
2. Select the preset "Default".
3. Turn off all effects (Mi Sound Effects)
4. Reboot the phone.

If the sound recovered, the problem was the software. If not, go back to the physical cleaning methods.

For Xiaomi on Android 13+, it is also useful to check the settings for Additional sound settings (there can be activated mode "Silent sound" or "Monosound").

💡

Before any cleaning of the speaker, be sure to check the software settings. In 15% of cases, the problem is solved by resetting the sound profile, and physical intervention is not required.

Prevention: how to protect the speaker from clogging

Cleaning the dynamics is a time-consuming process, so it's better to prevent pollution.

• 📱 Use a speaker protection case (e.g. Spigen Neo Hybrid for Xiaomi).
• 🧴 Apply a hydrophobic coating (e.g., Nano-Coating) once every 6 months.
• 🚫 Don’t put your phone in your pocket with coins or keys – they scratch the net.
• 🌬️ Blow the speaker regularly (1 time per month) with dry air (for example, a dryer in cold mode).

If you're often in dusty environments (construction sites, workshops), seal the speaker with a thin membrane (sold in electronics stores) that lets in sound but traps dust particles.

For Xiaomi owners with a retractable camera (such as the Mi Mix 3), the speaker should be cleaned every 3 months – the camera mechanism attracts dust, which then settles on the speaker.
