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.
