摘要

Improvements in the sound devices for talking dolls, essentially characterized by the constitution of a mechanism that allows to perform the continuous operation of a sound device of the class that has a disk with spiral grooves, provided with acoustic recordings of sounds and voices through incisions of variable depth and that are crossed by a pointed stylet whose vibrations are transmitted by contact to a vibrating cone of rigid structure, so that at the end of the sound reproduction cycle corresponding to the central situation of the reproductive system, it is returned to the periphery of the disc to perform an identical cycle of reproduction, without apparent solution of continuity.
