What Is an Earpiece Microphone?

The handset is the part where the handset is placed on the user's ear. Contains transmitter and receiver, which can be removed from the fixed device, allowing users to move around during a call. It may be connected to a fixed device via a wire, while for a cordless phone it is connected via a wireless signal.

Some people, due to their inattention, held the microphone inappropriately when they called, or held it too high, with their noses facing the microphone, and the breathing sound was more pronounced during transmission; On the neck, the speaking voice deviates from the microphone, causing the voice to be low. In this case, since the sound wave emitted from the mouth cannot directly act on the vibration membrane of the microphone, the microphone is not in an optimal state. Acoustic-electric conversion efficiency is naturally low. The correct way to hold the microphone is to keep the microphone in a vertical position, and the distance between the mouth and the microphone should be about 5-10 meters.

In addition, when calling, you should also be careful not to shake or shake the microphone with fatigue, to avoid making it vibrate. Because an induction coil is connected to the microphone circuit, there is a certain inductance. If the internal circuit of the microphone is intermittent due to artificial vibration, it will cause high pressure between the carbonaceous sand grains and cause sparks, which will easily burn the carbonaceous sand grains and affect the sound transmission effect ^[2] .
