Electret Condenser Microphone For Surface Mounting And Main Board Including The Same

摘要

Wherein electret capacitor microphone is mounted on the inside that relatively large circuit element or component installation can all be easily installed the motherboard that will not prepare a separate space and its manufacturing process for electret capacitor microphone, includes identical be simplified the present invention relates to an electret capacitor microphone and a motherboard. It include: a shell according to electret capacitor microphone of the invention; One acoustic processor is used to an external acoustic signal be converted to an electric signal, and acoustic processor is by shell seal; One printed circuit board, including an acoustic hole, wherein printed circuit board removal include the sound in electric signal and amplify electric signal to generate an acoustical signal, printed circuit board comprising a pad is used to deliver acoustical signal to an outside. Electret capacitor microphone and motherboard include identical not using an interface board, it is used to combine electret capacitor microphone to motherboard, a space required for use in installation electret capacitor microphone minimizes, one manufacturing process is simplified, to reduce by a cost, it is used for electret capacitor microphone and manufactures and install.
