Abstract
A reinforced music box includes a base portion, a two-sided cogwheel, a step type cogwheel, a music generator, a cover portion and a friction set. The two-sided cogwheel is disposed in the base portion and may rotate axially. The cover portion has a main part, a friction part and a supporting part. The main part, friction part and supporting part are integrally formed and either the main part or supporting part has a plurality of engagement holes that can engage with the fixing protrusions of the base portion. The friction set has a friction part and a spirally cogged stick. The spirally cogged stick may engage with the second cogwheel of the two-sided cogwheel at 90 degree. Therefore, the cover portion, which is integrally formed, may provide better protection and the cost in manufacturing and assembly may be reduced.
