Abstract
The arrangement for suppressing structure-borne sounds in microphones comprises an electroacoustic transducer which substantially includes a housing part, a diaphragm firmly connected to said housing and receiving the sound, and a corresponding transducer system and in which the electroacoustic conversion of the signal is based on the relative motion between the diaphragm and the transducer system, the natural resonance as well as the logarithmic decrement of said transducer system being at least approximately equal to the natural resonance and the logarithmic decrement of the diaphragm. Microphone types include moving voice coil, electrostatic, and ribbon.
