This is a type of electrostatic condenser microphone, which eliminates the need for a polarizing power supply by using a permanently charged material.
Electret microphones are used to convert sound into an electrical signal and are used in a wide variety of consumer electronics products, including cell phones, GPS devices and voice recognition equipment.
Specifications:
Sensitivity:- 44 + 2dB (0dB=1V/ubar.1KHz)
Impedance:2.2KΩ
Frequency: 20~ 16.000Hz
Maximum operating voltage: 10V
Standard operating voltage: 4.5V
Current consumption:0.5mA max.
Sensitivity reduction: within 3 dB at 2-1.5 V8
S/N ratio: more than 60dB
