How to Clean Speaker on Your Xiaomi Phone

During the day, we are constantly using our smartphone, so it gets dirty quickly. If the screen and the case can still be protected from contamination thanks to the film and cover, then the speakers and microphones get a lot of microparticles(dust, sand, and small foreign objects). In today’s article, we will tell you how to clean the speaker on your Xiaomi phone, what items you need, and how to conduct the procedure at home.

What causes the speaker to get dirty?

All cases have slots for speakers and microphones. Otherwise, the case material would block the sound, and you would be unable to communicate with callers and listen to music properly. But because the speakers are always open, they quickly get dirty. For example, the phone is lying on the table while you eat lunch, and bread crumbs fall into the holes. Or you use a mobile device on the beach and find that sand has completely clogged up the speaker’s mesh. It’s also not uncommon for the water to get inside, which becomes a real problem.

Even if the user is careful to use the smartphone, the holes will still be clogged with dust over time. Therefore, you must know how to clean the speaker on Xiaomi and Redmi. Remember that the methods of cleaning from microparticles and water are different. In the second case, you must be careful not to drive water deep into the case.

To check the contamination of the speaker is very easy: turn on any music or beep at maximum volume. If the sound is quiet, with an occasional hiss or even wheezing, then it’s time to start cleaning.

Proper cleaning of the speaker in the Xiaomi smartphone

Consider how to clean the speaker grid and connectors on the smartphone’s top and bottom end. The procedure can be carried out independently without turning to a master.

What you need

For mechanical cleaning, you will need the following tools:

  1. A few cotton swabs.
  2. Alcohol solution.
  3. An ordinary vacuum cleaner or compact hand-held vacuum cleaner.
  4. Toothbrush.
  5. Toothpick.
  6. Duct tape (masking tape).

A cotton cloth and a hair dryer will suffice if the holes are clogged with water.

How to get rid of dirt mechanically

Below you will find step-by-step instructions on how to clean the hearing and polyphonic speaker on Xiaomi and the microphone.

A cotton swab and alcohol

The most common and effective way.

  1. Please turn off the phone and place it on a flat surface like a table.
  2. Soak the cotton swab in alcohol. The solution should not drip on the speaker, so you need minimal alcohol.
  3. Gently wipe the grid of the speaker with the cotton swab. The alcohol will remove small dirt.
  4. Repeat the same steps with the microphone and other speakers. This method will be useless if there is a solid foreign object in the holes.


Use an ordinary wooden toothpick if a hard foreign object in the microphone or speaker connector will not dissolve under alcohol. Make a few gentle movements to remove the foreign object from the hole. Be careful and cautious, or you may damage the connector.


This method will help eliminate the dust that collects on the surface of the speaker grid. A small handheld vacuum cleaner is best, but an ordinary one can also be used.

  1. Remove the brush from the vacuum cleaner and set the minimum power.
  2. Bring the tool close to the smartphone, but not too close. Approximate distance: 2-4 cm. Clean the grid until the dirt is completely removed by the air jet. Usually, cleaning will not take more than a minute.

You may additionally use a cotton swab dipped in alcohol or a toothpick.

Sticky Material

Also a good option for cleaning the speaking speaker on Xiaomi. It is recommended to use painter’s tape. If you don’t have it handy, use regular clear tape. Carefully stick the tape on the grill and go over it with a cotton swab. Repeat the procedure several times, changing the adhesive area. The scotch tape will pick up the small contaminants. If sticky residue remains on the screen afterward, remove it with alcohol or a special display cleaner.

Cleaning the speaker using the system function

MIUI has a speaker cleaning function. It starts a loud beep, which removes dust and other small impurities. This method is not always effective, but you can easily eliminate dust. Let’s look at the step-by-step procedure for MIUI 13:

  1. Go to “Settings” and go down to “Advanced Settings”. Open the “Speaker Cleanup” tab.
  2. Set the volume to maximum and activate the slider. A beep will be played for 30 seconds. If the dirt is not completely removed, activate the function several times. For the best effect, shake your smartphone gently.

This is how you can clean the speaker sound on Xiaomi. If the speaker wheezes when you turn on the function, it means mechanical damage, and it is better to go to a master for repair. Also, be sure to visit the service center if the speaker does not work at all. Experienced users can subdue or replace this part themselves.


What to do if there is water in the speaker?

Tilt the smartphone gently and shake it to get moisture out of the speakers. Wipe the connectors with a dry cotton cloth. Take your hair dryer and switch to cold air. Direct the air jet into the speakers. The distance should be at least 5 centimeters. The smartphone completely fell into the water – then wipe the holes with a napkin and leave the mobile device in a bowl of rice for 12 hours, putting an airtight bag on top. Rice absorbs moisture.

What to do if the second main speaker does not work?

Subbing the speaker at home is problematic, so it is better to contact a master. You may need to replace the element.

How to improve hearing if the conversational speaker produces a quiet sound?
