1. A toy doll comprising a body including at least one arm pivotally mounted on said body and a sound reproducing device mounted in said body including a rotatable grooved phonograph record, transmission means operatively connected between said record and said arm for rotating said record in a predetermined direction upon oscillation of said arm;

  • a diaphragm support movably mounted in said body for movement between a first position adjacent said record and a second position spaced from said record, a diaphragm mounted on said diaphragm support above said record, a tone arm having a first end portion engaged with said diaphragm and a needle mounted therein for operative engagement with said record;

    means for mounting said tone arm for swinging movement in a plane generally parallel to the record to allow the needle to track in the grooved record and for movement towards and away from the record with said diaphragm support, said tone arm being located generally between the record and the diaphragm;

    means carried by said diaphragm support and engaged with said tone arm for moving the tone arm between said first and second positions with said diaphragm support and defining a start position for the tone arm in a predetermined location relative to the record while permitting said swinging movement of the tone arm;

    spring means for normally biasing said diaphragm support into said first position adjacent the record whereby the needle engages the record to reproduce sound upon rotation thereof and for normally biasing said tone arm towards said start position;

    said transmission means including means for selectively moving said diaphragm from said first position to said second position upon movement of said arm to a predetermined position relative to said body whereby the needle is disengaged from the record and returned to its start position;

    said spring means comprising a first spring for biasing the diaphragm support to its first position and a second spring for biasing the tone arm to said start position and against the record; and

    said means carried by the diaphragm support comprising a frame element having an elongated slot formed therein positioned above the record and extending along the plane of swinging movement of the tone arm, a portion of said tone arm being engaged in said slot.
