ABSTRACT:
An electro-acoustic transducer for low frequencies ranging from 0-5000 Hz uses a plurality of parallel spaced apart, alternately disposed, fixed and movable diaphragms, in addition to which the motion inducing forces on the movable diaphragm are distributed over the area of the diaphragm and assembly of the electro-acoustic transducer is achieved by the use of modular elements.
