Abstract
A music box is arranged for increased compactness. The music box includes a comb having vibrating teeth, a drum with a rotational axis with a plurality of pins on an outer surface for engaging ends of said teeth, a coil spring having a winding shaft for driving the drum, an accelerating gear row for accelerating the rotation speed of the spring winding shaft, a braking member engaging with the gear row for braking and a base frame for transmitting the vibration of the comb to a mounting member. The rotational axis of the drum and the spring shaft are arranged vertical to the base frame and the spring shaft is substantially centered on the frame. The drum, comb, accelerating gear and brake are disposed about the centered spring shaft to provide a more compact arrangement.
