Abstract: A remote-control doll assembly in which a high-frequency sound signal produced by squeezing a toy baby bottle actuates an internal motor to raise the arms of the doll and actuates an internal voice mechanism to simulate a crying sound. Insertion of the nipple of the bottle into the mouth of the doll opens a switch to interrupt the crying sound. In an alternative embodiment, a radio signal is used as a control signal. In another modification of the invention, a pressure-sensitive rattle is used to produce the control signal.

Abstract: A heartbeat simulator for a toy doll or the like comprises a resilient, relatively soft rubber diaphragm supported at its edges in a housing and formed with curved surface portions to provide a popping movement between an equilibrium position and a displaced position. A motor is periodically energized to displace the diaphragm by winding a cord attached at one end to the motor shaft and at the other end to the diaphragm and is immediately thereafter de-energized to permit the diaphragm to unwind the cord and return to its equilibrium position. A connecting tube acoustically couples the diaphragm to the mouth of the toy doll to produce a simultaneous breathing sound.
