Over time, it becomes clogged with dust, villi from your pocket or skin particles, leading to wheezing, muffled sound or complete absence of the interlocutorβs voice. Many users mistakenly think that the problem lies in a software failure or damage to the microphone, but in 80% of cases it is the clogged speaker who is to blame.
In this article, we will discuss 5 proven cleaning methods, from the simplest (with a toothpick) to advanced (ultrasonic bath), you will learn how to return a clear sound without the risk of damaging the membrane or contacts, and also what you absolutely can not clean the speaker Redmi Note 8 Pro. All methods are tested on real devices and do not require special skills.
Signs of a clogged speaker: when it's time to clean
Before you start cleaning, make sure that the problem is with the dynamics, not the microphone or system settings.
- π The sound is quieter than usual (the interviewee complains that he canβt hear you well, even though youβre speaking into the microphone).
- π Wheezing or crackling appear during a conversation, even if the speaker's grid is visually clean.
- π΅ The sound disappears completely, but after a slight tap on the body resumes.
- π« Visible clusters of dust or villi under the speaker grid (can be viewed with a flashlight).
If at least one of these features is apparent, the speaker needs cleaning. On the Redmi Note 8 Pro, the speaker is located at the top of the screen (near the front camera), not on the bottom edge - this is important to consider when cleaning.

- Cut a small piece of tape (5-7 mm wide), paste it on the speaker grid, then rip it off abruptly. Repeat 2-3 times.
- Blow the speaker with your mouth (not too much!) or use a spray of compressed air (if any).
This method is effective in removing:
- π§΅ Villus from clothing or fabric.
- π« Dust accumulated on the surface of the grid.

- π¦ Bacteria and microbes (alcohol disinfects).
π‘
If you don't have isopropyl alcohol on hand, you can use a screen cleaning fluid (no ammonia!) to apply it to a microfibre wipe and wipe the speaker.
Method 3: Ultrasonic cleaning (for advanced users)
If the speaker is heavily clogged and previous methods have not worked, you can use an ultrasonic bath, which requires caution, but gives you the best result.
What you need:
- π Ultrasonic bath (you can buy an inexpensive model for jewelry).

Method 5: Disassembly of the phone and deep cleaning (extreme method)
If all the previous methods didn't work, the last option is to take the phone apart and clean the speaker from the inside, which is risky, but sometimes necessary.
What will be required:
