  • Mechanical musical movement with electronic light control
    Patent number: 6291749
    Abstract: A musical movement in which a drum has a series of pins that engage the reeds of a vibration plate to play a tune. The movement includes a cam disk which rotates with the drum. A switch is activated by the cam to energize a circuit for flashing a plurality of lights in pseudo-synchronism with the music played by the musical movement. In that way, the distinctive sound of a mechanical musical movement is combined with efficient, computer controlled flashes from light emitting diodes or high intensity micro incandescents.
