ABSTRACT:
A microphone connector reliably inhibits electromagnetic waves from entering the microphone even if their frequencies are high as in the case of cellular phones or the like. The microphone connector10A is of a three-pin type having a connector base11which consists of an electric insulator and a first pin for earthing, a second pin and a third pin for signals, which are penetratingly provided in the connector base. The microphone connector includes a printed circuit board placed on a connector base11and a shield cover200covering the printed circuit board100. The printed circuit board100is a two-sided substrate having a shield layer on its bottom surface which layer consists of a solid pattern of a copper foil. The printed circuit board100has a capacitor element and a Zener diode element mounted in parallel, the capacitor element inhibiting entry of high frequencies, the Zener diode element preventing the circuit from being electrostatically destroyed. Almost the entire top surface of the substrate is covered with the shield cover200.
