ABSTRACT:
A capacitance-type electrostatic transducer is provided that can be operated in an environment where it may be subjected to excessive mechanical vibrations. Unwanted gain variations and/or spurious electrical signals produced by said transducer when operated in such an environment are precluded by preventing relative movement between the spring that urges the backplate into cooperative engagement with the vibratile diaphragm of the transducer and said transducer backplate, at the point of contact between said spring and said backplate.
