Where is the microphone in the phone Xiaomi: layout schemes for all models

Have you noticed that the person who is listening to you is not hearing well while you are making calls, and voice messages are recorded with noise? The reason may lie in a contaminated or faulty microphone on your Xiaomi smartphone. But before you carry the phone to the service center, it is worthwhile to figure out exactly where the microphones in your model are located - there can be two to five of them, and each is responsible for its function.

In this article, we will take a look at the Redmi Note 12/11/10, POCO X5/F5, Xiaomi 13/14 and other popular models with photos and circuits, and how to test the performance of microphones without special tools and what to do if one of them fails, and pay special attention to hidden microphones for noise reduction, which many users do not even know.

How many microphones in Xiaomi smartphones and why there are so many

Xiaomi’s current smartphones come with at least two microphones, while flagship models (such as the Xiaomi 14 Ultra or Black Shark 5 Pro) have four or even five.

• 🎤 Main microphone – used for calls and voice recording (located at the bottom of the case).
• 🔊 Second microphone – responsible for noise reduction during conversations (usually near the main or on the upper edge).
• 📱 Third microphone for recording stereo video (found in models with support for Dolby Atmos).
• 🎧 Microphone in a 3.5 mm connector - if it is in the model (for example, POCO X3 Pro).
• 📶 Additional microphone for antennas – in some flagships to improve communication.

This number of microphones is required for:

• ✅ Clear voice transmission in noisy places (due to technology) AI Noise Cancellation).
• ✅ Video stereo recordings (your voice sounds natural and surrounding sounds are volumetric).
• ✅ Improved voice recognition for Google Assistant or XiaoAI.

⚠️ Warning: If the caller hears an echo or your voice is interrupted, the problem may not be in the main microphone, but in the noise suppression – it is often contaminated by dust or moisture.

Where is the main microphone: diagrams of popular models

The main microphone in Xiaomi is almost always located at the bottom of the case, next to the USB-C connector or speaker, but its exact position may vary depending on the series.

To accurately identify the microphone, shine a flashlight into the intended hole — inside must be a metal mesh (the speaker is plastic). On some models (for example, Redmi 9A), the microphone is hidden under a common grille along with the speaker.

Where is the second microphone for noise reduction?

The second microphone in Xiaomi is responsible for suppressing noise during calls, which analyzes the surrounding sounds and subtracts them from your voice so that the person hears you clearly even on the subway or on the street, its location is less obvious:

• 📱 Most of the Redmis and POCO — on the upper edge next to the IR port or slot for SIM-map.
• 🎤 In flagships (Xiaomi 13 Pro, Mix Fold 3) – on the back side next to the main camera.
• 🔊 In some models (for example, Black Shark) – on the front panel above the screen (under the frame).

This microphone is often contaminated because it is located in places where dust accumulates (for example, near the surface of the microphone). SIM-If you notice someone complaining of hissing or crackling during a conversation, the problem is probably that person.

⚠️ Warning: Do not confuse the second microphone with the light sensor (a small circular hole next to the front camera.

💡

To check if noise cancellation is working, call another phone and compare the sound quality in a quiet room and outside, and if it doesn't matter, the noise reduction microphone is faulty or disabled in the settings.

How to check the microphone Xiaomi without special programs

Before you carry your phone to the service, you can independently check the microphones using standard MIUI tools:

1. Recorder: Open the Dictaphone app and record 10 to 15 seconds of speech. Listen to the recording — if the voice sounds muffled or jammed, the problem is with the main microphone.
2. Calling the answering machine: Call any number with an answering machine (for example, *100# for some operators) and leave a voice message. If your voice is not heard, the microphone for calling is defective.
3. Video: Take a short video and check the sound. If it's recorded from only one direction (for example, only the front), the extra microphone for stereo doesn't work.

For more accurate diagnosis, you can use the engineering menu:

Enter the phone code in the app: ##4636##


Go to the section "Phone Information" → "Mic test"




Speak to the microphone – the screen should display the signal level (green bars).)

Record voice in voice recorder |Call on voicemail |Call video with sound |Clear the engineering menu (##4636##)|Clear the microphone holes-->

If none of the methods showed problems, but the interlocutors still do not hear you well, the reason may be:

• 🛠️ Software failure (needs resetting or flashing).
• 📶 Bad network signal (try calling over Wi-Fi).
• 🔋 Battery savings (turn off Ultrasaving mode in settings).

How to Clean the Mik on Xiaomi at Home

Most often, microphone problems are caused by contamination of the holes with dust, pile or moisture, and you can clean them yourself without disassembling the phone:

1. Airflow: Use a compressed air canister (to clean keyboards). Hold the balloon vertically 5-10 cm from the microphone hole and blow out the dust with short presses.
2. Soft brush: Take a soft bristling toothbrush or makeup brush. Walk gently through the microphone holes without pressing hard.
3. Scotch or sticky tape: Cut a small piece of scotch, fold it with a sticky side outside and lightly press against the microphone hole - the dust will stick.

⚠️ Warning: Do not use cotton swabs, toothpicks or needles under any circumstances - they can damage the microphone's protective netting or push dirt deeper. Also avoid liquids (alcohol, water) unless you are sure that the housing is tight.

If the microphone is filled with liquid (for example, after rain or spilled drink):

1. Turn off the phone immediately and remove it. SIM-map.
2. Place the device in dry rice or silica gel for 24 to 48 hours.
3. Do not turn on the phone until you make sure it is completely dry (you can check the moisture indicator if it is in the model).

💡

If the microphone still doesn't work after cleaning, the problem may be that the contacts on the board are damaged, and professional repair is required.

What to do if the microphone is not working after the MIUI update

Sometimes the microphones stop working after updating the firmware or resetting, because of software conflicts or incorrect permissions.

• 🔄 Reboot your phone – sometimes it helps to reset temporary errors.
• 📱 Check the permissions for the microphone: Go to Settings → Annexes → Permit management → Microphone: Make sure that the calling apps (phone, WhatsApp, Telegram) have access to the microphone.

Reset the network settings

→ SIM-maps and mobile networks → Network reset

This can help if the problem is related to communication settings.

Reverse to the previous version of MIUI

1. Download the old firmware from the Xiaomi Firmware website.
2. Go to Settings → About Phone → System Update → Three Dots → Select a firmware file.

If you have one of these models, be especially careful when cleaning - a non-standard arrangement increases the risk of damaging the microphone.
