Abstract

This invention relates to an improved light display/projection system which synthesizes an infinite variety of pleasing geometrical patterns in response to electrical stimuli. When a hi-fidelity sound system is used to provide audio signals, the unit becomes suitable as a self-contained home or commercial entertainment device. Accordingly, the invention is described as an electrical signal to visual pattern conversion system comprising a housing, within which is operably assembled; at least one electromechanical transducer adapted to receive an audio frequency electrical input; at least one mechanical, pneumatic or electromagnetic or combination thereof coupling device for each transducer, coupling the transducer to at least one elastic membrane fixedly attached at its peripheral edge with a suitable clamp; at least one mirror attached parallel to the outer surface of the, or each, membrane and; at least one laser source positioned so as to direct light to the, or each, mirror. The housing containing the above components having at least one window consisting of a clear transparent material, or a screen of thin translucent material or a combination thereof. In operation, movement of the membrane(s) in response to electrical input cause the mirror(s) to deflect the incident light beam(s) producing a moving pattern of light that may be displayed on the screen or projected from the housing onto another surface.
