Abstract
Abstract An audio system having an output which is varied by a rotating disc. The disc has sections of high and low resistance. The audio signal is coupled through a transformer and the resistive disc element to an output transducer, and is also coupled to a second output transducer without being coupled through the resistive disc element.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
67 words
A sound disperser comprising a disc having a progressively resistive segment and a comparatively non-resistive segment, a wiper in contact with said disc, motive means continuously driving said disc so that it traverses said wiper repeatedly, a sound transducer, a signal source, means connecting said source to one of said disc and wiper, and means connecting said sound transducer to the other of said disc and wiper.
Claim 2
Dependent Claim
67 words
A sound disperser comprising a disc having a progressively resistive segment and a comparatively non-resistive segment, a wiper in contact with said disc, motive means continuously driving said disc so that it traverses said wiper repeatedly, a sound transducer, a signal source, means connecting said source to one of said disc and wiper, and means connecting said sound transducer to the other of said disc and wiper.
Claim 3
Dependent Claim
32 words
The sound disperser of claim 1, further comprising a transformer coupled between said source and said transducer, said disc and wiper being connected between the secondary of the transformer and said transducer.
Claim 4
Dependent Claim
27 words
The sound disperser of claim 2, further comprising a second transducer and a second transformer coupled between the primary of said first transformer and the second transducer.
Claim 5
Dependent Claim
15 words
The sound disperser of claim 1, further comprising a second transducer connected to said source.
