Where is the microphone on the phone Xiaomi Redmi: diagrams for all models

Are you trying to record a voice message but the person complains of poor hearing? Or during a video call your voice disappears? The reason may lie in the wrong location of the microphone on the Xiaomi Redmi smartphone. Unlike flagship models, where microphones are often duplicated, budget and mid-budget Redmis often have only 1-2 main microphones - and they are easy to accidentally cover with a finger or a case.

In this article, you will find the exact microphone layouts for all popular Xiaomi Redmi ranges (including Redmi Note, Redmi Pro and Redmi K-series), learn how to check their performance and avoid typical errors in use, and we will also discuss why the microphone sometimes “disappears” from the system after a MIUI update and how to fix it.

Why it’s important to know where the microphone is on Xiaomi Redmi

You might think that what a normal user would want to know is the physical location of the microphones, but there are at least 5 reasons why this is critical:

• 🎤 Sound quality when you call. If you hold your phone so that the microphone is closed with your finger, the person will hear you intermittently or not at all.
• 📹 Video problems. Many people complain that when recording video, the sound is recorded quietly or with interference, often because of the wrong position of the hand.
• 🔇 If the phone falls on the side where the microphone is, there's a high probability of damage.
• 🛠️ Repair and cleaning. Dust and dirt accumulate in the microphone holes, making the sound worse.
• 🔄 Problems after the update. MIUI «Loses the microphone in settings – without knowing its physical location, diagnosis is difficult.

For example, in the Redmi Note 10 Pro, the main microphone is located at the bottom of the case next to the Type-C connector, and the second (noise suppressing) is at the top next to the speaker, and if you cover the bottom with your palm while you call, the person will hear only noise.

⚠️ Note: Some models (e.g. Redmi) 9A) There's only one microphone, and if it gets clogged with dust, the sound will disappear completely.

The location of the microphones depends on the line and generation of the smartphone. Below are the current schemes for the most common models. If your model is not on the list, focus on the same design (for example, the Redmi Note 11 and Redmi Note 11 Pro have the same location).

Note that on models with stereo speakers (such as the Redmi K60), additional microphones can be placed next to the top speaker to improve noise cancellation. If you are not sure where the microphone on your model is located, use a flashlight to shine on the end of the phone, and you will see a small hole (sometimes covered with a grid).
