ABSTRACT:
A toy doll includes a sound reproducing device having a rotatable grooved record and a transmission for rotating the record in a predetermined direction upon oscillation of the doll's arm. A tone arm bearing a needle is supported in the doll's body for engagement with the record and has one end thereof engaged against a sound reproducing diaphragm. The diaphragm is mounted for movement towards and away from the record in response to selective positioning of the doll's arm and is operatively engaged with the tone arm to draw the tone arm away from the record when the diaphragm moves away from the record, while permitting the tone arm to move along the surface of the record as the needle tracks in the grooves thereof. A spring arrangement normally holds the tone arm engaged with the record, and applies a biasing force biasing the record towards the start position. When the doll's arm is moved to the appropriate position, the diaphragm and tone arm are moved away from the record and the spring arrangement returns the tone arm to its start position.
