ABSTRACT:
A transmission structure is set forth for a crystal-like ball, which comprises a glass ball and a rubber seal; the center of the rubber seal has a tube-shaped round hole for receiving a shaft of a rotary structure; the shaft extends from the inside of the glass ball to the outer end of the rubber seal, and connects with a universal joint; the shaft is to be driven in rotation with a transmission structure so as to actuate an ornament in the glass ball to rotate. The outer edge of the open end of the glass ball is connected with the upper edge of a hollow and round ornament; the bottom edge of the hollow and round ornament is glued onto an outer top surface of a base disc on a base. The hollow and round ornament is a transparent member, through which a rotary ornament therein can been seen. The bottom edge of the rotary ornament is glued onto the ring surface of the turntable on the base; the turntable is mounted on a projected ring of the base disc. The upper edge of the turntable is engaged with a small gear of the transmission structure by means of an inner gear of a ring member. The center of the base disc is mounted with a music generator having a driving spring to actuate a driving gear to drive the transmission structure so as to have both an ornament inside the glass ball and the ornament in the hollow and round ornament rotated.
