Abstract
A miniature microphone component comprises a miniature condenser microphone, conductive rubber contacts formed and fixed on a terminal area of the miniature microphone and a rubber casting (also called “bushing”) for protection against vibrations covering the circumference of the miniature microphone. To install the miniature microphone component, it is sufficient to insert the miniature microphone component into a small-size communication device so that the conductive rubber contacts formed and fixed on the terminal area of the miniature microphone are pressed against terminal portions on a circuit board. Thus, the working efficiency of the assembly can be considerably increased and the installation space can be minimized.
