Light show projector
First Claim
1. A light show projector for use in projection of a light beam onto a projection surface, said projector comprising:
- a projector housing;
a substantially point light source mounted within said housing, said light source producing a narrow light beam;
color means for imparting variably changing color to said light beam;
means for focusing said light beam;
a mirror for reflecting the light beam outwardly from the housing for projection onto the projection surface;
resilient support means for movably supporting said mirror relative to said housing, said resilient support means including at least, one active resilient support member coupled to said mirror and at least one passive resilient member coupled to said mirror;
a transducer mounted on said housing and including means for movably driving said at least one active resilient support member; and
means for variably displacing said transducer in general synchronized relation with an audio input signal, whereby said mirror is movably displaced by the combined driven action of said at least one active resilient support member and resistive action of said at least passive resilient support member to displace said mirror in an .complex and multidimensional manner producing a complex line pattern of changing color on the projection surface.

Abstract
A light show projector is provided for use in producing a pleasing and variable laser-like visual line pattern on a wall or the like in synchronized relation with an audio input signal such as music. The light show projector comprises a compact and portable housing having a substantially point light source projecting a narrow light beam through a rotatable color wheel having multiple radial segments of different colors, and further through an adjustable focusing lens for reflection by a dynamically supported mirror onto a wall or ceiling of a room for viewing. The mirror is resiliently supported by asymmetrically arranged support members, one of which is electromagnetically displaced in relation to selected characteristics of the audio input signal, thereby producing a multidimensional mirror displacement yielding a large and widely variant esthetically attractive laser-like line pattern. The appearance of the line pattern is enhanced by variably driving the color wheel in relation to other characteristics of the input signal to produce a changing multicolored display for observation while listening to music.
