Abstract
A sound producing device producing different tones when rotated in front of a light source. A light transducer mounted at one spot at the surface of the device produces signals corresponding to the amount of light illuminating the light transducer. An oscillator is coupled to the light transducer and to a speaker to produce the tones. A motion switch is coupled to the oscillator to shut off production of sound when the device has been left at rest for a certain time period.
