ABSTRACT:
A musical electric signal generated by electric signal generator 1 is supplied to a rhythm signal extractor 2 so that a rhythm signal is extracted. Interval data of rhythm signal peaks are stored in memory 3. Cycle detector 4 detects a musical rhythm cycle based on the interval data stored in the memory 3 and then provides a rhythm synchronizing signal in synchronization with the rhythm. The rhythm synchronizing signal is utilized as a control signal for moving portions of a toy.
