Abstract
A music box structure with composing function comprises primarily a comb reed composed of teeth which are tuned to play various musical notes, a motor-driven cylinder, and a plurality of pins, wherein on a surface of the cylinder are disposed a plurality of spaced jack holes corresponding to the teeth of the comb reed. When in use, a user may insert pins into various jack holes on the cylinder according to various music scores or the user's own composition with the inserted pins having an appropriate protrusion height. When the cylinder is driven to rotate by the motor, the inserted pins pluck the teeth at various positions on the comb reed in order and produce music.
