Electret microphone

Electret Condenser Microphone, also known as electret microphone, is composed of two parts: acoustoelectric conversion and impedance conversion, and is the most popular microphone. The basic principle is to use a capacitor as an acoustic signal-electrical signal converter. A plate of this capacitor can sense the change of sound pressure and play the role of sound signal intake. The collective microphone has the characteristics of small size, simple structure, wide frequency response range, high signal-to-noise ratio and low cost, and is suitable for mass production.

Application: Widely used in headsets, mobile phones, computers, tablets, smart communication and other devices. The volume of Yuanjing's resident microphones ranges from φ9.7mm to φ3.0mm, and there are various types of microphones including wire-bonding, pin-type and patch-type microphones to choose from.
