ABSTRACT:
A pair of photoconductive elements are provided on an inner surface of a light transmitting outer skin of a doll. When the amount of light impinging on either one of the pair of photoconductive elements differs from the other as a result of interruption of the light impinging on the one of the photoconductive elements, a sound generating device is actuated to generate a sound.
