Abstract
Abstract A light display apparatus comprising a plurality of light sources controlled by circuitry and a display screen. The display apparatus can project images of an object onto the screen in several relative positions to create apparent motion in coordination with a sound wave signal. Illumination of the respective light sources is coordinated to respond to various amplitudes of a sound wave signal by contact structure placed in different actuated positions under control of divers voltage amplitudes of an output signal from an audio-amplifier.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
Light display apparatus comprising light means, object means, and screen means, said object means being physically located intermediate the light means and the screen means, said light means having at least two laterally spaced light sources and comprising light circuit means and control circuit means, said light circuit means having a contact means operable by the control circuit means to any one of a plurality of effective positions, and the control circuit means comprising input terminals, trigger means, and resistant means, said input terminal means being adapted to Receive an audio-signal, said trigger means operating the contact means between positions when the trigger means are caused to be energized beyond a predetermined amplitude by the audio signal for consecutively illuminating the light sources to respectively cast light upon said object means in time relation to thereby project an image of the object means upon the screen means first in one position and then in another position so that the image appears to be in motion.
Claim 2
Dependent Claim
165 words
Light display apparatus comprising light means, object means, and screen means, said object means being physically located intermediate the light means and the screen means, said light means having at least two laterally spaced light sources and comprising light circuit means and control circuit means, said light circuit means having a contact means operable by the control circuit means to any one of a plurality of effective positions, and the control circuit means comprising input terminals, trigger means, and resistant means, said input terminal means being adapted to Receive an audio-signal, said trigger means operating the contact means between positions when the trigger means are caused to be energized beyond a predetermined amplitude by the audio signal for consecutively illuminating the light sources to respectively cast light upon said object means in time relation to thereby project an image of the object means upon the screen means first in one position and then in another position so that the image appears to be in motion.
Claim 3
Dependent Claim
59 words
Light display apparatus comprising: a pair of light sets, relay actuated switch means operable in a first position to energize one of said light sets and operable in a second position to energize the other of said light sets, an audio signal source having an output voltage, and relay means applying said output voltage to actuate said switch means.
Claim 4
Dependent Claim
59 words
Light display apparatus comprising: a pair of light sets, relay actuated switch means operable in a first position to energize one of said light sets and operable in a second position to energize the other of said light sets, an audio signal source having an output voltage, and relay means applying said output voltage to actuate said switch means.
Claim 5
Dependent Claim
33 words
The apparatus of claim 2 further comprising: variable resistance means interposed between said audio signal source and said relay means for selecting the amplitude of said output voltage for actuating said relay means.
Claim 6
Dependent Claim
17 words
The apparatus of claim 2 further comprising: means normally biasing said switch means to said first position.
Claim 7
Dependent Claim
17 words
The apparatus of claim 2 wherein: said audio signal source is one channel of a stereo amplifier.
