Abstract

A kind of condenser microphone with graphene diaphragm, comprises graphene diaphragm (M), has the back pole plate (4) of through hole, between diaphragm (M) and back pole plate (4) by insulating ring ( 3) There is an interval d between the diaphragm (M) and the back plate (4), and the diaphragm (M) and the back plate (4) are respectively connected to the power supply and amplification component (6) through the conductive component (5) , so that the diaphragm (M) and the back plate (4) form a capacitor, aiming at the different distances d between the diaphragm and the back plate that form the capacitive structure, different means of powering are used to realize the function of the microphone, and how to make the microphone with A technical problem with the normal operation of the microphone with the graphene diaphragm. Electroacoustic characteristics such as sensitivity, frequency response, and transient response of the microphone of the present invention are greatly improved compared with traditional condenser microphones.

Description

technical field [0001] The invention belongs to the field of microphones, in particular to a microphone with a graphene diaphragm. Background technique [0002] Microphones include condenser, dynamic, piezoelectric, etc. Among them, condenser microphones have been widely used for their relatively excellent electroacoustic characteristics, and the diaphragm, as an important component of condenser microphones, has an important impact on the performance of the microphone. The material of the microphone diaphragm in the prior art is usually a polymer material with a metal coating, metal, etc. Due to the limitation of the material, the performance of the microphone still cannot meet the increasingly stringent use requirements sometimes. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention proposes a microphone with a graphene diaphragm, which uses different means of powering to realize the function of the microphone fo...
