AbstractA microphone provided with a suspension diaphragm which serves to support a freely suspended microphone cartridge, preferably of the electret type, the suspension diaphragm being substantially coplanar with the acoustic diaphragm of the microphone cartridge. At least one groove entirely closes acoustically the air-gap surrounding the freely suspended microphone cartridge. The groove is further provided with lug-shaped flanges, one for clamping the microphone cartridge and the other for suspension from a frame, mount or microphone case. The suspension diaphragm is particularly suitable for light-weight microphone cartridges.
