How to clean the speaker on Xiaomi Redmi 5: safe methods without disassembling the body

Xiaomi Redmi 5 is one of the most popular budget smartphones, but over time, its speakers get clogged with dust, skin particles and even moisture. This leads to sound distortion, wheezing or the complete disappearance of bass. If you notice that the speaker or multimedia speakers have become quieter or with interference, the problem is likely physical pollution. In this article, we will discuss 3 proven ways to clean the speakers without opening the case, and also tell you how to avoid damage to the membrane and what to do if the sound is not restored.

It’s important to understand that Redmi 5 speakers have a fine safety net that gets clogged over time even when used carefully. Unlike flagship models, there’s no active dust protection (like the Xiaomi 13 Pro), so cleaning is required more often, and the wrong actions – using sharp objects, wet wipes or a vacuum cleaner – can permanently put the speaker out of order.

Before you start, make sure that the problem is the pollution, not the software failure.

1. Restart your smartphone – sometimes the sound is lost due to temporary errors.
2. Check the volume settings in Settings → Sound.
3. Connect the headphones – if the sound in them is clean, the problem is precisely in the speakers.

Signs of a clogged speaker on Xiaomi Redmi 5

How do you know if a speaker needs cleaning, not replacing? Here are the key symptoms that indicate contamination:

• 🔊 Muffled sound – basses disappear, high frequencies become quieter.
• 🎵 Wheezing and crackling when playing music or during calls.
• 💨 Air noise – the speaker can be heard “breathing”, especially when the volume is increased.
• 📵 Complete absence of sound in one of the speakers (on Redmi 5 there are two of them: conversational and multimedia).
• 🌫️ Visible dirt under the grid - if you shine a flashlight, you can see the accumulation of dust.

If any of these symptoms are present, cleaning will help to bring the sound back to normal, but there are also false symptoms that are often confused with pollution:

If you've ruled out all alternative causes, move on to cleaning. Start with the safest method.

Method 1: Compressed air cleaning (the safest way)

This is a method that can remove dust and fine particles without damaging the membrane, and you'll need a can of compressed air (sold in electronics stores or household goods), and don't use a home vacuum cleaner or a hair dryer, which creates too much airflow and can warp the speaker.

Algorithm of action:

1. Turn off your smartphone to avoid short circuits when moisture hits.
2. Keep the canister vertically at a distance of 10-15 cm from the speaker.
3. With short presses (1-2 seconds), blow the net. Don't point the jet at an angle, just perpendicular.
4. Repeat for the second speaker (conversational).
5. Wait 5-10 minutes before turning on so that the condensate evaporates.

If there is no compressed air, you can use a rubber pear (for example, to blow out cameras), which creates a less intense flow, but also effective for surface cleaning.

💡

After purging, check the sound at maximum volume - if the wheezing is left, proceed to the next method.

⚠️ Attention: Do not use WD-40 Or other aerosols to clean the speakers, and they leave an oil film that attracts even more dust and can dissolve the adhesives inside the body.

Method 2: Brushing with a toothpick or soft brush

If the compressed air didn't work, it means the dirt is tightly entrenched in or under the net, and mechanical cleaning will help, but it's important to be careful not to puncture the membrane.

• 🪥 Plastic or wooden toothpick (not metallic!).
• 🖌️ Soft brush (for example, for drawing or makeup).
• 🔦 Lantern (for illumination).
• 🧴 Alcohol wipes (for disinfecting tools).

Step-by-step:

1. Wipe your toothpick with an alcohol towel to remove fat and bacteria.
2. Carefully, without pressing, use a toothpick to run the speaker across the grid, scraping visible lumps of dirt, and move parallel to the body, not inland.
3. For hard-to-reach places, use a brush - it sweeps dust from under the net.
4. After cleaning, blow the speaker with compressed air (see Method 1) to remove the remaining particles.

On Xiaomi Redmi 5, the speaker is above the screen and the multimedia speaker is on the bottom end. Be especially careful with the conversational speaker: its membrane is thinner and easier to damage.

Don't press on the grid - the membrane is thinner than paper!

Do not use needles or pins

Do not brush with a wet toothpick

Do not try to get dirt from under the net deeper than 1 mm.-->

⚠️ Warning: If you've had a toothpick that makes the sound worse (metal ringing or no bass at all), you've damaged the membrane.

Method 3: Removal of dirt with sticky tape (for persistent contaminants)

This method is suitable if the dynamics has accumulated fibers of fabric, wool or sticky particles (for example, after carrying the phone in your pocket with keys). To clean, paint tape or tape with non-aggressive glue. The method is more risky than previous ones, but effective for removing dense contaminants.

How to clean:

1. Cut a small piece of scotch (3-4 mm wide).
2. Carefully press it against the speaker grid with the adhesive side down.
3. Without jerking, pull the tape upwards - it will pull out dirt particles.
4. Repeat 2-3 times, each time using a new piece of scotch.

This method works well for a multimedia speaker on the bottom end where more debris accumulates. For a conversational speaker, use a tape no more than 2 mm wide so as not to touch the sensors.

On Redmi 5, the speaker is combined with the proximity sensor - if you overdo it with tape, you can disrupt the automatic screen shutdown during a call.

What to do if the speaker wheezes after cleaning?

Sometimes when you clean it, it doesn't make any sense, or it gets worse, and here are the possible causes and solutions.

• 💧 Moisture inside the case – if cleaned with wet tools, dry your phone in rice or silica gel for 12–24 hours.
• 🔧 Membrane damaged – if metal ringing is heard, the speaker must be replaced.
• 📱 Software Failure – Reset the Sound Settings: Go to Settings → System system → Resetting settings → Resetting the sound settings.
• 🔌 Bad plume contact – if the sound disappears when the phone is tilted, you need to analyze and check the connections.

If the problem is moisture, don't use a hair dryer - it can melt the internal elements. Better put the phone in a bag with silica gel (there is in shoe boxes) for a day.

For the diagnosis of membrane:

1. Call your phone and listen to the sound at maximum volume.
2. If distortions are heard even at a quiet volume, the membrane is damaged.
3. If the sound is clean at low volume but wheezes at high volume, the problem is with the amplifier or plume.

💡

If the speaker doesn't work after cleaning, and you've eliminated moisture and software failures, you probably need a replacement. On Redmi 5, it costs 500-1,200 rubles at the service center.

How can we prevent re-contamination?

To keep Xiaomi Redmi 5 speakers cleaner for longer, follow these tips:

• 📱 Use a speaker-protected case – many models have special protrusions that lift the phone above the surface.
• 🧴 Regularly wipe the net with a dry soft cloth (microfibra).
• 🚿 Avoid moisture – even after rain, dry your phone for 1-2 hours.
• 🎧 Connect headphones in dusty conditions (for example, on construction or public transport).
• 🔄 Clean the speakers every 3-6 months, even if there are no problems with the sound.

If you often carry your phone in your pocket with keys or coins, wrap the speakers in a thin film (like screen protection) that lets you hear the sound but traps large particles, and you need to change it once a month.

For the Redmi 5, it is especially important to monitor the multimedia speaker on the bottom end – it is more likely to be clogged due to proximity to the surface of the table or pocket.

When cleaning will not help: signs of malfunctioning speaker

Sound is not always a problem with pollution, and here are the cases where cleaning is useless and needs repair.

• 🔇 Total lack of sound in all speakers (including headphones) – faulty audio chip.
• 🔊 Sound is only in headphones - the problem is in the amplifier or plume of the speakers.
• 📞 The speaker is working, but the multimedia speaker is not (and vice versa) – one of the speakers is damaged.
• 🔥 Phone overheats when sound is played - short circuit in audio track.

If you see at least one of these symptoms, contact the service center. on Xiaomi Redmi 5 replacement speaker is inexpensive (from 500 rubles), and attempts to repair yourself can lead to damage to the board.

For diagnosis, you can use the test of speakers:

1. Type on the keyboard ##4636##.
2. Select Audio → Speaker Test.
3. Listen to the test signals – if one of the speakers is not sound, it is faulty.

💡

On Redmi 5, the speaker is more likely to fail – its membrane is thinner, and it works in harsher conditions (humidity from breathing, dust during conversation).
