ABSTRACT:
The vibratable diaphragm of an electret transducer has in its central plate portion one or more formed ribs, ridges or projections resting of a substantially flat backplate. These support the active regions of the diaphragm with precise spacing from the backplate. Elongate projections can be formed to relieve membrane stresses in the diaphragm. The flexural stiffness of the diaphragm is sufficient in itself to provide mechanical stability of the diaphragm in the presence of the destabilizing forces of electrostatic attraction by the backplate.
