摘要

A device for the intermittent operation of voices for dolls, driven by a bellows, characterized in that in the front edge of the movable upper bellows cover there is a projection that during the movement of the bellows cover rubs with a corrugated device delaying and accelerating several times in a row the movement of the bellows in such a way that several times in a row more or less air passes through the voice which, due to this cause, acquires vibrations, and intermittent differences in tone.
