What is the small hole next to the iPhone 13 camera?

The small hole next to the iphone13 camera is a microphone, which adopts a dual-mark noise reduction design. It is used to assist the secondary microphone to collect sound. It can be used to reduce environmental noise and improve the clarity of call speech. Since the subject's sound reception is poor due to environmental noise when shooting video, most smartphones are currently equipped with multiple noise reduction microphones on the body to record the noise of the surrounding environment, combined with noise reduction. Algorithm to achieve noise reduction effect.
