  • Patent number: 4836075
    Abstract: The present invention relates to an improved musical cube. The cube includes circuitry mounted within its cubical housing with the circuitry including three two-axis switches with each such switch having a central open position and two positions, one to either side of the central position, each side position of which closes a particular unique sub-circuit. The three switches are mounted in the housing in mutually perpendicular relation and the switches combine to control the operation of six sub-circuits. In the operation of the improved musical cube, a read-only memory and synthesizer device are incorporated into a circuit with the read-only memory being pre-programmed with a distinct musical sequence for each of the six sub-circuits.
