The microphone, the scientific name for the microphone, is to convert sound to electrical energy conversion devices from "Microphone" the transliteration of the English words. Also known as the microphone, microphone. 20th century microphone from initial development through resistors convert electric inductance and capacitance conversion, a large number of new microphone technology has been developed, including strip, moving-coil microphones, as well as the current widespread u According to the principle of acoustic and electric conversion is divided into: electric (moving-coil, strip), capacitive (DC-polarized), piezoelectric (Crystal, ceramic-type), as well as the electromagnetic type, carbon, such as semiconductor.

According to field force divided into:-pressure, differential pressure, modular, line-column, and so on.

According to the signal transmission is divided into: Wired and wireless.According to purpose are divided into: measurement microphone microphone, recording microphone, voice microphones, musical instruments, and so on.Directivity is divided into: heart-shaped, sharp, heart-shaped, Super, heart-shaped,bi-directional (Figure 8), Omni (Omni).

Electret microphone small size, low cost, widely used in telephones, mobile phones and other devices.

Micro-silicon microphone based on CMOSMEMS technology, smaller. Consistencyconsistency than electret capacitor microphone 4 times times, so the microphonearray with MEMS microphone especially suitable for high performance applications, which matches better microphone improves sound wave forms and to reduce the noise.

Laser microphones used in the hacking.se of condenser microphone and electret microphones.
