ABSTRACT:
The invention relates to electroacoustic transducers and more particularly to microphones in which the conversion of an acoustic vibration into an electric voltage is provided by a piezoelectric diaphragm. The purpose of the invention is to allow transducers to be formed by mass production methods with a minimum of parts for providing the functions of embedment of the diaphragm, connections, screening, acoustic filtering and protection against damp and dust.
