Xiaomi Redmi 8T is a popular budget smartphone that is still in use today for its reliability and maintainability. However, over time, many owners face problems with sound: the volume goes down in the dynamics, then the sound is distorted during conversations. To diagnose a malfunction, you first need to know exactly where the speaker on the Redmi 8T is located - and there are as many as three of them here!
In this article, we will understand:
- 📍 The exact location of each speaker (main, conversational and optional) with photos and diagrams
- 🔍 How to distinguish speaker malfunction from program failures
- 🛠️ Possible causes of breakdowns and ways to eliminate them without contacting the service
- 📱 Step-by-step instructions for checking sound through the engineering menu
Important: The design of the Redmi 8T (codenamed ginkgo) is different from the newer Redmi models, using a classic layout with a separate talk speaker, rather than a single multimedia module, which makes repairs easier, but requires a precise understanding of which element failed.
How many speakers in Xiaomi Redmi 8T and their purpose
Unlike the flagship smartphones with stereo sound, the Redmi 8T is equipped with three speakers, each of which performs its function:
- Speaker (top) - used for voice calls and notifications, located at the top of the case next to the front camera.
- The main speaker, which is responsible for playing music, video and system sounds, is located on the bottom end next to the USB-C connector.
- An additional microphone speaker (sometimes mistakenly called a "second speaker") is used to cancel noise during calls, not visible externally, because the main speaker is hidden under the grille.
Curious fact: in some firmware Redmi 8T main speaker can work in tandem with the spoken to create a pseudostereo effect, but it depends on the version of MIUI.
Where is the speaker on Redmi 8T: photo and diagram
The speaker, also called "audible" or "top," is the smallest of the three, and it's located at the top of the screen, right of the front camera, under a plastic grille, and the photo below shows its exact location:
Design features:
- 🔹 The speaker is glued to the metal frame of the case, which complicates its replacement without special tools.
- 🔹 The grille above the speaker is often clogged with dust, making the sound muffled, and can be cleaned with a soft brush or compressed air.
- 🔹 When the smartphone drops down the screen, this speaker suffers first - its contacts can move away from the board.
⚠️ Attention: If the speaker stopped working after the screen was replaced, it is likely that the master damaged the plume or did not connect the connector on the motherboard.
💡
To check if the speaker is working, call another phone and put your ear on the top of the Redmi 8T. If the sound comes only from the bottom speaker, the problem is in the top module.
Location of the main (multimedia) dynamics
The Redmi 8T's main speaker is responsible for playing music, video and system sounds, and it's located on the bottom end of the case, to the right of the USB-C connector, under a decorative grille, which is easily confused with a microphone, but there are key differences:
| Element | Location. | Appearance | Function |
|---|---|---|---|
| Main dynamics | Right of USB-C. | Grid with 7-9 holes | Music, video, games. |
| Microphone | Left of USB-C. | Grid with 3-5 holes | Voice recording, noise cancellation |
| Additional speaker (microphone) | Under the bars of the main | Not visible. | Improving call quality |
Frequent problems with the main dynamics:
- 🎵 Distortion of sound at high volume - a sign of damage to the membrane or moisture.
- 🔇 Complete lack of sound – may be caused by disconnection of contacts or a failure in the firmware.
- 📱 Sound only in headphones - check the sound output settings in Settings → Sound.

If the sound does not appear after these actions, try using the engineering menu:
- Open the Phone app.
- Enter the code ##4636##
- Select Phone Information → Audio tests.
- Test all the speakers in turn (there will be hints on the screen).
Critical signs of hardware failure:
- 🚨 The sound disappears only in speakers, but works in headphones.
- 🚨 When playing music, wheezing or crackling can be heard.
- 🚨 The speaker doesn’t make any sounds even in the engineering menu.
⚠️ Warning: If the sound is quieter or wheezing after the phone falls, don't try to clean the speaker with a needle or toothpick! this can damage the membrane. Use only a soft brush or a spray of compressed air.
Frequent causes of breakage of speakers and repair methods
According to the statistics of service centers, 80% of the problems with sound on the Redmi 8T are due to four reasons:
| Reason. | Symptoms | Decision |
|---|---|---|
| Dust clogging | Muffled sound, wheezing | Cleaning with compressed air or soft brush |
| Moisture intrusion | Distortion, total absence of sound | Rice drying (24+ hours) or changing the speaker |
| Disconnection of contacts | The sound disappears when you press the body | Disassembly and soldering of contacts |
| Firmware failure | The sound only works in headphones. | Resetting or flashing |
Self-repair is only possible in cases of clogging or software failures, and replacement speakers will require:
- 🔧 Setting screwdrivers T3-T5 and plastic blades.
- 🔥 Hair dryer for softening glue (temperature not higher than 80)°C).
- 🛒 New speaker (article for conversational: Xiaomi) 18040L-001, For the main one: Xiaomi 18030L-001).
