A compilation of improvements and modifications to U.S. Pat. No. 5,392,358 which discloses an electrolytic loudspeaker assembly ( ) which reproduces a broad band of audio signals. The assembly ( ) is comprised of a thin, non-magnetic capacitive transducer ( ) which consists of compound diaphragm ( ) that is further comprised of a center section ( ), a front section ( ) and a rear sect compound diaphragm ( ) is enclosed by a frame assembly ( ). The improvements and modifications to the assembly designs for a center section ( A, A); three designs each for a front section ( A, A, A) and a rear section ( A, A, A); three designs for a frame assembly ( A, A, A) and two designs for a transducer driver unit ( ). The basic design of the assembly ( ) is also augmented by the addition of an acoustic wave diffuser, reflector, and absorbing assembly ( ) and an acoustic baffle structure ( ).

Electrolytic loudspeaker assembly

An advanced design for an electrostatic and an electrolytic loudspeaker assembly ( ) that comprises a compound diaphragm ( ) sandwiched between a first metal stator ( ) and a second metal stator ( ), wherein each stator includes a multiplicity of perforations ( ). All the sides of the stators ( ) as well as the inside surface of the perforations ( ) are coated with an insulating material ( ) also known as ACOUSTAGUARD&trade; ( ) which includes a base coat ( ) and a sealing and pigmentation coat ( ). The coats ( ) and ( ) are applied by a unique process that allows ACOUSTAGUARD&trade; to be applied at room temperature by preferably a spraying technique. The application of ACOUSTAGUARD&trade; avoids any arcing or corona discharge between the two stators ( ) which can distort the audio output and damage the loudspeaker assembly ( ).

Electrostatic and electrolytic loudspeaker assembly

A compound electrolytic loudspeaker ( ) comprising two major elements: a capacitive transducer ( ) and a transducer driver unit ( ). The capacitive transducer ( ) consist of a compound diaphragm ( ) that is suspended within a frame assembly ( ) and which consists of a front stator ( ) having a front stator electrode ( ), a rear stator ( ) having a rear stator electrode ( ), and a center diaphragm ( ) having a diaphragm electrode ( ). The electrodes interface with the transducer driver unit ( ) which receives and amplifies an audio signal applied from a receiver-amplifier ( ). The amplified audio signal drives the capacitive transducer ( ) in synchrony with the reveived audio. The capacitive transducer ( ) is designed to be used singularly or be positioned in several selectable placement configurations including a side-by-side configuration, a stacked vertical configuration and in a horizontal configuration wherein an inner surface ( ) of a first frame assembly ( ) abuts with an outer surface ( ) of a second frame assembly ( ).
