Abstract
An animated audio doll whose mouth can be driven by replaceable tape cartridges is provided. The doll has a head member with simulated eyes and mouth that can open and close. Uni-directional direct current motors are provided in the body of the doll and are connected to the respective eyes and mouth through flexible driven links that protect the motor if either the eyes or the mouth are held stationary. The tape cartridge can be encoded with audio signals, a base frequency and a pair of coordinated frequency timing signals. The tape player can convert the frequency timing signals into digital signal levels while a binary switch member can determine when the mouth is in a closed position. A level detector circuit can determine whether the first or second timing signals are present and a logic circuit can, in combination with the timing signals and the output from the binary switch, drive the DC motor connected to the mouth in coordination with the audio sounds. A separate motor can drive the eyes in coordinated movement in a vertical and horizontal direction to contribute to the realistic simulation of an animated object.
