How many microphones does the mobile phone have?

In the early years, mobile phones used to be a microphone, usually near the charging port at the bottom of our mobile phone, but a microphone is prone to noise when talking, which affects our call quality.

But in recent years, due to the rapid rise and competition in the electronics industry, mobile phone manufacturers have also tried their best to make higher-quality mobile phones. Two microphones have been added. You can look at the top of your mobile phone receiver or Is there a small hole on the top? Then this hole is the position of the second microphone. Generally, we use the microphone below the phone when we make a call. When we turn on the hands-free or video call, we use the microphone above. , Don’t speak loudly into the microphone below if the other party can’t hear you in the future.

There are also iPhone phones that have three microphones to improve the quality of calls. The third one is usually near the flash of the rear camera. It is usually used for recording. So many microphones have their own functions, and the noise reduction of calls has played a role. Not a small effect!
