Abstract
A voice or sound unit adapted for use on toys and the like has a mechanical linkage system with a joint capable of transmitting sound indicia while isolating the tone arm from any absorption of stylus movement. The tone arm can employ flexure hinges to insure a constant force on the stylus. A planetary gear coupling system provides a unique drive transmission to either a single turntable or a pair of concentric turntables. If a pair of turntables are used, they can be relatively rotated to combine a large number of sound sequences.
