| 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.

I claim:
1. A sound producing toy ball comprising:
- speaker means mounted within said ball;
- power supply means mounted within said ball;
- switch means coupled to said power supply means and mounted within said ball;
- light sensing means mounted on a surface of said ball, said light sensing means producing a first signal whose value is dependent on the amount of light received by said light sensing means;
- converting means coupled to said switch means, said power supply means, said speaker means and said light sensing means, said converting means converting said first signal to a second signal having a frequency dependent on said value of said first signal;
- said converting means outputting said second signal to said speaker means for producing an audible tone whose pitch is dependent on said frequency of said second signal;
- control means coupled to said switch means, said power supply means and said converting means, said control means for disabling said converting means when said switch means does not change state for a fixed period of time;
- whereby a tone whose pitch is dependent on the amount of light received by said light sensing means is produced.
