Abstract

본 발명은 마이크로폰 카트리지에 관한 것으로서, 마이크로폰 카트리지의 케이스의 구조를 개선하여 메틸라이징된 고분자필름 또는 고분자필름만으로 진동막에 의하여 정전유도가 발생되도록 함과 동시에 고정전극이 케이스와 절연되도록 함으로써, 원가를 절감시키고 별도의 절연부품이 요구되지 않도록 하며, 증폭소자의 출력선과 접속되는 회로기판의 회로동판과 케이스와 접속된 접지동판과의 절연부위를 선상으로 형성함으로써 노이즈 유입이 최대한 감소되도록 한 것이다.The present invention relates to a microphone cartridge, which improves the structure of the case of the microphone cartridge, so that only the methylated polymer film or the polymer film causes electrostatic induction by the vibrating membrane and the fixed electrode is insulated from the case, thereby reducing the cost. To reduce the noise and to avoid the need for separate insulation parts, the inflow of the circuit copper plate of the circuit board connected to the output line of the amplifying element and the ground copper plate connected to the case are formed in a line to minimize noise inflow.
