ABSTRACT:
A microphone for stethoscopes and the like having a weighted head member with a recessed cavity formed therein. A diaphragm is sealed to the head member with an adhesive material to provide an airtight cover for the cavity. The mass of the head member causes it to remain substantially vibration free and as a result all vibrations are transmitted directly to the diaphragm causing it to vibrate with increased amplitude at all frequencies. The adhesive seal between the diaphragm and the head member effectively eliminates secondary vibration thereof so that the microphone is capable of producing a distortion free air signal of high amplitude at all normal frequencies.
