Animated display controlled by an audio device

Claim 1

An animated display device comprising: an audio tape player of cassette type having a recorded audio signal track, an animated liquid crystal display and addressing circuitry including a plurality of electrically-conductive matrices arranged in the form of segments representing portions of the eyes and eyebrows and mouth of a human face in different positions suggesting different facial expressions and a driver and driving circuitry having terminals electrically connected to the matrices, an amplitude detector for outputting signals according to the reading of the audio signals of the tape, an analog comparator connected to the amplitude detector for outputting digital signals according to the amplitude of the audio signals, a microprocessor having programmed means for reading the output of the analog comparator and delivering electronic signals to the driver, a power source for powering the tape player and microprocessor and amplitude detector, a selector button shiftable between a ready operating mode and a fast forward non-playing mode and a stop mode and an eject mode, and a housing for accommodating the tape player and liquid crystal display and microprocessor and amplitude detector and power source and selector button, all adapted and arranged for the driving of the liquid crystal display by the driver in animating the facial expressions in seeming synchronization with the tape recorded audio on the cassette tape as transcribed by the player with the facial expressions being changeable responsively to the voltage selectively applied at portions of the liquid crystal composition where the eyes and eyebrows and mouth are represented.
