Abstract
An optical disk player includes a main body, a cover engaging with the main body, a pivot module, and a deceleration module. The pivot module includes a torsion spring, two ends of the torsion spring being fixed on the main body and the cover respectively. The deceleration module includes a first deceleration portion arranged on the main body and a second deceleration portion arranged on the pivot module. The first deceleration portion contacts the second deceleration portion and frictional forces therebetween reduces the speed of opening the cover.
