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.
Claims1
An electrostatic transducer the combination comprising:
- a. two outer dielectric diaphragms carrying conductive layers which are laminated in a parallel condition to
- b. a one-piece dielectric spacer/centrally fixed and perforated conductive grid serving as an essential skeletal structure wherein
- c. geodesically-curved transducer arrays are configured and result in broadened sound radiation patterns in the vertical and horizontal dimensions of the listening area
- d. non-resonant dampening means for joining adjacent transducers thereby decoupling adjoining speaker units without loss of structural integrity
- e. a laminated dielectric/conductive tab which serves as a diaphragm signal connection electrode as well as a diaphragm interconnecting system allowing adjacently curved geodesic diaphragms to be "interwired" without bulky connectors or strands of wire
- f. a transformer to which its primary winding is supplied a signal voltage and to which its secondary winding is connected across said electrostatic transducer's diaphragm conductive layers;
- and, there being an additional connection of a high voltage d.c. biasing potential to said electrostatic transducer's fixed conductive grid via its electrode connection point.
