<p>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 are precluded, at reduced cost, by mechanically attaching the electrically conductive transducer spring (32) that urges the backplate (24) into cooperative engagement with the vibratile diaphragm of the transducer, to the transducer backplate (24). A cylindrical boss (30) on a flat upper surface of the backplate engages a wedge-shaped hole (36) in the spring as the spring is inserted during assembly (arrow).</p> |
