ABSTRACT:
A driving mechanism of a wave-producing ornament is mounted in a base of the ornament and includes a motor which rotates a disc. A connecting link is pivotally connected at a first end to an outer periphery of the disc and at a second end to a lower end of a push bar. The push bar is located in a channel integrally formed on the base of the ornament and has a round head projects from a top opening of the channel to contact with an end of a liquid container of the ornament above the base. When the disc rotates, it brings the connecting link to move in a circular motion and pull and push the push bar to descend and ascend along the channel reciprocatingly. Whereby, the liquid container is periodically lifted and lowered at one end by the round head of the push bar to produce waves in the container. A crank is pivotally connected at an inner end to the pivotal point on the disc with a decorated outer end projecting from a long slot on the base of the ornament, so that the rotating disc shifts the crank and causes the decorated outer end of the crank to reciprocate in the long slot.
