Many people still don’t know the uses of this small hole

Have you ever wondered about the small, unassuming round hole at the bottom of your phone? Many people overlook this feature, but it actually serves a crucial purpose in enhancing your overall calling experience.

The small round hole at the bottom of your phone is actually a secondary microphone, playing a vital role in the dual microphone system that helps reduce noise. This is a noise-canceling microphone, integrated into most modern smartphones. Thanks to this microphone, your calls will be clearer and of higher quality. Without it, your voice wouldn’t be transmitted clearly to the listener.

Even in noisy environments, you can still hear and transmit your voice clearly thanks to this small hole. Placing the microphone at the bottom of the phone near your mouth helps capture and transmit your voice better, enhancing call quality.

Sound waves pass through this microphone and are amplified, allowing the listener on the other end to receive clearer audio. Without the secondary microphone, call quality would significantly decrease.

Most mobile phones today have two noise-reducing microphones, one at the top and one at the bottom. When the phone is affected by environmental noise, the secondary microphone reduces this noise, leaving only the call’s audio. This technology, known as “dual microphone noise reduction,” makes calls clearer even in noisy environments.

The purpose of this secondary microphone is to work in tandem with the primary microphone, located at the top of the phone, to capture and transmit your voice more effectively. By using both microphones, your phone can better distinguish between the desired audio (your voice) and unwanted background noise.

This dual microphone system is particularly useful when you’re making calls in crowded or loud settings, such as a busy street or a noisy office. The secondary microphone at the bottom of the phone helps filter out these external sounds, ensuring that the person on the other end can hear you clearly.

So, the next time you make a call, take a moment to appreciate the unsung hero – the small round hole at the bottom of your phone. This seemingly insignificant feature is an essential component that contributes to the overall quality and clarity of your phone conversations.

Remember, the next time you’re on a call and you need to be heard clearly, the small round hole at the bottom of your phone is there to help you out.
