ABSTRACT:
A coupling member for coupling a capacitive microphone capsule to a preamplifier housing to form a rod-shaped microphone assembly, comprises a shaped body made of vibration absorbing elastic electrically conducting material. A contact pin extends axially in the shaped body and has at least a portion made of vibration absorbing elastic electrically conductive material. The shaped body and contact pin form first and second electrical connections between the capacitive microphone and the preamplifier. In this way noise which is transmitted through the solid body of the amplifier does not reach the capacitive microphone to generate objectionable low-frequency sounds.
