Electret Condenser Microphone
The electret condenser microphone receives sound through a diaphragm to produce a change in capacitance, and then the signal is amplified by a triode. The products are available in omnidirectional, unidirectional, and noise-canceling options, and the 3mm diameter design is suitable for various portable products. In addition, depending on the customer's needs, customers can customize the microphone to be waterproof (IP67), anti-electromagnetic interference, and TDMA noise resistant.
