The small round hole on your phone is actually a secondary microphone, an essential component of the dual microphone system designed to reduce noise. This noise-canceling microphone is a standard feature in most modern smartphones, ensuring clearer and higher-quality calls. Without it, your voice may sound unclear to the listener.
Even in noisy environments, this microphone allows your voice to be transmitted clearly. Its strategic placement—usually near the bottom of the phone, close to your mouth—helps capture your voice more effectively, enhancing call quality.
The sound waves picked up by the microphone are amplified, ensuring the person on the other end hears you clearly. Without a secondary microphone, call quality would be noticeably poorer.
Most smartphones today are equipped with two noise-canceling microphones: one at the top and another at the bottom. This dual-microphone noise reduction technology filters out ambient sounds, isolating your voice for better clarity, even in loud surroundings.
