Abstract
An electroacoustic assembly comprising a microphone having a diaphragm and supported on a face plate susceptible to vibratory effects. Vibration sensitivity is reduced by opposing the pressure effects on the diaphragm caused, on the one hand, by vibration of the assembly in the ambient air mass and by vibration of the air mass leading from the ambient air mass to the diaphragm, and on the other hand, by vibration of the effective mass of the diaphragm, generally augmented with additional mass, and including the effect of the internal air mass adjacent the diaphragm. Applications include hearing aids in which the microphone and its support are mechanically coupled to receiver components that may impart significant motion thereto.
