Abstract
A simplified electrostatic loudspeaker consisting of two outer diaphragms laminated to a one-piece dielectric spacer/grid electrode which serves to separate the diaphragms, hold the bias voltage as well as provide the essential skeletal structure whereby a geodesically-curved surface transducer is configured to provide broadened sound radiation dispersion in the vertical and horizontal dimensions of the listening environment. Additionally, said diaphragms carry external conductive layers whereby a transformer coupled signal voltage is applied through a unique laminated conductive connection tab which results in a minimum stray resistance and capacitance signal interconnection system.
