Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 265 words
An apparatus for producing sound from a visual image source comprising: a. a high intensity light source producing a light beam; b. a member having a slit therein for passing said beam therethrough; c. a first plurality of transmitting optic fibers arranged with their first ends in a closed curvilinear line and their second ends in an open line pattern; d. optical means including a rotatable shaft and a mirror mounted thereon for rotation adjacent said slit for receiving said light beam and sequentially reflecting said beam, said optical means including a lens mounted on said shaft for rotation therewith for receiving said light beam reflected from said mirror, and reducing focusing and projecting said beam sequentially upon the first ends of said optic fibers; e. an elongated recorded film movably located adjacent the second ends of said fibers for receiving said beam thereon; f. a second plurality of receiving optic fibers arranged with their first ends in spaced registration with the second ends of said first plurality of optic fibers and their second ends arranged in a compact pattern; g. optical focusing means mounted adjacent the second ends of said second plurality of optic fibers for receiving the image from said film and focusing said image; said last named image being focused on a photo detector wherein a signal is passed to an audio amplifier which in turn is transmitted to a speaker system; and h. means for moving said recorded film and operatively connected to said rotatable shaft of said optical means for synchronizing the movements of said mirror, lens and recorded film.
