Abstract
A music box includes a sounding mechanism and a pause mechanism. The pause mechanism has a guide sleeve, a stopper member, a pushbutton, a guide assembly and a restoring spring. The guide sleeve is formed with a plurality of initial locating sections, a plurality of stop locating sections and a communicating ring section. The stopper member can be moved and rotated as well as has a stop block. The pushbutton serves to push the stopper member to move in a forward direction. The guide assembly serves to drive the stopper member to rotate, while the restoring spring serves to push the stopper member to move in a backward direction. By means of the pushbutton, the guide assembly and the restoring spring, the stop block can in turn move between the initial locating sections, the stop locating sections and the communication section.
