Abstract
A dynamic vibration absorber for a disk player includes a deck base, a deck plate movably disposed on the deck base to support a spindle motor that spins a disk, a mass body disposed around the deck plate, and a flexibly changeable connection member that connects the deck plate and the mass body. A dynamic vibration absorber including the mass and connection member reduces vibration generated when the disk spins using a reciprocal action of the mass body and the connection member relative to the deck plate.
