  • Patent number: 4169335
    Abstract: A musical amusement device of the type designed to display miniature figures generally representing one or more humans playing musical instruments wherein one or more of the figures, either the human characters or instruments, are mechanically interconnected to one of a plurality of speakers. Each one of a possible plurality of speakers are electrically interconnected to a frequency selector in the form of filter and control circuitry which in turn is electrically connected to a sound source such as a stereo amplifier, etc. The circuitry is designed to allow only sound of a predetermined frequency range to be transmitted to the speaker which in turn causes coincident movement of the individual figures due to a mechanical, movable interconnection between the speakers and the figures themselves.
