Luckily for you, there is an explanation for this, and that is what we are going to talk about now. The idea is to clarify this point so that you can pass on the information to those who do not know about this unusual detail.
What is the function of the little hole, after all?
Anyone who has noticed this on their cell phones might think it is something insignificant, but its function may surprise you. This is because it is very important during calls.
If you have an iPhone, you may notice this small hole between the camera and flash. However, other devices may have it in different places, such as on the top, near the headphone jack or the charger port.
That hole between the camera and the flash is nothing more than a secondary microphone. However, it is not just any microphone, because its job is to reduce noise that may interfere during the call.
Another purpose for it is to pull audio recordings and convert the sound emitted to increase its intensity when recording.
In other words, this little hole has a very important job, so that you can be understood in the best way possible by whoever is on the other end of the line. And even in recordings, since the idea is to pull the sound in the best possible way so that there is not so much noise.
One example is that this microphone can separate the voice of the person on the call from a horn, for example. This way, the secondary sound is quieter and you can still understand who is talking to you. It’s a great way to avoid having to worry about not understanding who called you or vice versa.
