Rotation-driven structure for music box
 A rotation-driven structure for a music box is disclosed. The structure generally includes a music generator, a driving disc, a transmission cap, a housing, a cover, and a plurality of planetary discs. The music generator produces music and employs the driving disc and the transmission cap to transmit driving force originating from the music generator to rotate the housing and the cover simultaneously so that the rotations of the cover and the planetary discs rotate reversely to each other.
