A music box includes a box, an operation unit, multiple activation units and a comb member. A circuit board controls a coil in a desired one of the activation units to create a magnetic field with the magnetic plate so as to attract the activation plate to be matched with the match plate. The attached activation plate and the match plate are rotated by a shaft extending through the activation units. The shaft is driven by a driving member. Each activation plate includes fingers which push the keys of the comb member to generate sound.

Provided is a novel music box device that can play music for a long time and can also suppress a thickness. The present invention relates to a music box device including: a sheet that has a playing engagement part and is rotated by a driving means; a star wheel arranged oppositely to the sheet and having two or more claws on an outer peripheral surface; and a vibration valve arranged adjacent to the star wheel. In the music box device, as the sheet is rotated by the driving means, the playing engagement part is linked with one claw to rotate the star wheel while another claw plucks the vibration valve to play music, and the sheet has a helical plate shape.
