Patent attributes
In a condenser microphone having a form in which a microphone unit section and a power module section are separated and connected by a dedicated cable, and comprising a screw terminal for connecting the dedicated cable at the power module section, electromagnetic waves are effectively prevented from penetrating through the screw terminal section and noises are prevented from mixing in a voice signal. A power module section has a substrate, a screw terminal section fixed on the substrate and connecting a cable, and a shield case that covers the power module section, and the substrate has a wiring pattern for connecting the circuit of the power module section and the screw terminal section and a high frequency noise countermeasure component connected to the wiring pattern, and the screw terminal section is fixed on the substrate so as to cover the high frequency noise countermeasure component.
