摘要
对于驻极体电容传声器(ECM),不同结构部件的等效电容,对灵敏度的影响不同。在掌握了不同类别电容对灵敏度的影响机理之后,在单体设计时,对不同部件进行针对性的设计,以便按需调节单体的灵敏度。主要探讨了振膜的有效电容和传声器内部的寄生电容这两者对灵敏度的影响,以及各部件对相应电容的影响。
For Electric Condenser Microphone （ECM）, different structure parts equivalent capacitances have different effect on ECM sensitivity. Once the theory of different equivalent capacitance having different effect on sensitivity is mastered, structure parts are pertinently designed to adjust ECM sensitivity. Two contents are discussed：the active capacitance and the negative capacitance have effect on ECM sensitivity, every structure parts have effect on corresponding equivalent capacitance.
