FIELD: electro-acoustics, possible use for construction of sound-processing equipment, in various industry branches, implementing indicator-electrostatic generator-transformer for construction of equipment.
SUBSTANCE: method for forming characteristics of capacitor microphone includes sending signal from at least one immovable(movable) electrode of electrostatic transformer-generator to amplifier, processing of aforementioned signal by amplifier and sending of its portion to sound-processing device, portion of signal from amplifier output is sent to at least one movable (immovable) electrode of electrostatic transformer-generator via check connection, which additionally envelopes electrostatic transformer-generator. Block for sending additional portion of signal can be made in form of direct connection of amplifier output to movable (immovable) electrode of electrostatic transformer-generator by providing electric contact or in form of combination of correcting links to perform correction of electric and acoustic microphone characteristics and/or galvanic decoupling from polarization voltage.
EFFECT: higher quality of operation of capacitor microphone due to decreased sound distortions and production of stable microphone characteristics.
