The small hole next to the rear camera lens on iPhone phones has always aroused the curiosity of many about its true role, and whether it is just an aesthetic addition or a secret technical tool.
It turns out that this hole is not just a random hole, but rather a third microphone that Apple has added since the launch of the iPhone 5, to work alongside the other microphones located at the bottom of the phone and near the front speaker.
Its main purpose is to improve the sound quality when recording videos using the rear camera, ensuring that clearer and more focused sounds are captured.
In addition to enhancing recording quality, this microphone plays an essential role in Noise Cancellation technology. When making phone calls in crowded places, this microphone picks up ambient noise and processes it using advanced software algorithms to isolate it, allowing the speaker’s voice to reach the other party with crystal clarity and free of distortion.
With the development of the “iPhone” series of phones, especially in the “iPhone 16 Pro” models, “Apple” has enhanced the capabilities of these microphones to support “spatial audio” and “Audio Mix” functions, which reduces the need for users to have external microphones when shooting videos of almost professional quality.
Users are advised to be careful not to block this small hole with inappropriate “covers”, as closing it may lead to a noticeable decrease in sound quality during calls or the appearance of low and unclear sounds in video recordings.
