The role of the secondary microphone
The small, round hole at the bottom of your phone is a secondary microphone. It is crucial to the dual-microphone system used in most modern smartphones.
This secondary microphone is primarily responsible for noise-canceling, which greatly improves call quality.
The function of a secondary microphone.
Enhancing call clarity
The secondary microphone captures and amplifies sound waves. This helps ensure that your voice is transmitted clearly during calls.
It is especially important in noisy environments where background noise could otherwise interfere with your conversation.
By improving audio clarity, this microphone enhances the quality of your phone calls.
Supporting noise reduction
By working alongside the primary microphone, this secondary microphone helps reduce environmental noise.
This technology, known as “dual microphone noise reduction,” ensures that only the audio from your call is transmitted to the listener, improving overall call clarity.
Improving audio recording.
Beyond phone calls, this microphone also aids in recording clearer audio for videos and sound-related applications like video recorders, VLCs, and sound recorders. Its presence ensures that the audio captured is as clear as possible.
Maintaining phone functionality.
Blocking or interfering with this microphone can hinder its performance, leading to issues such as reduced audio clarity during calls and recordings.
Why you should avoid blocking the microphone
Interfering with or obstructing the small round hole can significantly impact your phone’s audio performance.
This is crucial, whether you’re making a call or recording a video.
The secondary microphone plays a key role in capturing and transmitting sound effectively. Ensuring that this hole remains unobstructed is essential for maintaining audio quality.
