The smallest details often go unnoticed, but they are often the ones that make the difference. In mobile phones, where each design has a purpose, there is an almost invisible but essential element: a tiny hole that everyone carries with them, although few know what it is for. That small hole, strategically located on the device, is much more than a simple design adornment.
What is that little hole and what is its function?
This is the secondary microphone, a key piece to ensure that calls and audio recordings are of high quality. Its main function is to reduce ambient noise, allowing your voice to be heard clearly even in noisy places.
All models, regardless of the brand, have it incorporated
This is possible thanks to a technology that combines sound capture with the elimination of external interference. Without this small component, phones would lose much of their basic functionality, such as clarity in conversations or voice recognition in virtual assistants.
The location of the microphone is no coincidence. By being close to the charging port or speakers, it captures the voice directly while minimizing noises that can obscure such as traffic or background conversations.

Therefore, this element is a perfect example of how engineers integrate invisible but effective solutions into devices to improve the experience. In addition, it is unlikely to be damaged: its strategic position protects the microphone from damage and ensures optimal performance in any situation.
Other functions of the secondary microphone
It is not only during calls where this element proves its usefulness. It also plays a crucial role in recording videos and audios. It allows you to obtain a cleaner and more realistic sound, something essential for those who use their mobile phone as a creative or professional tool. Even features like the voice assistant rely on this small hole to interpret commands accurately, regardless of surrounding noise.
