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.
