Disk player, self-compensating balancer integrated turntable, self-compensating balancer integrated clamper and self-compensating balancer-integrated spindle motor

摘要

Disclosed is a disk player having a self-compensating dynamic balancer capable of suppressing internal vibrations due to an eccentric mass of the disk, and a self-compensating balancer-integrated turntable, clamper and spindle motor employed therein.;The above-mentioned magnetic compensating balancer is installed in a rotating member inside a disc player. Preferably formed integrally with the rotors of the turntable, the clamper and / or the spindle motor. The balancer includes at least one race which is formed integrally with the rotary member and has a rotation axis as a rotation center, a movable member which is freely movable in the race, and a cover member which covers the opening of the race .;Therefore, when the self-compensating balancer is rotated, the movable member is disposed at a distance from the revolving center by the centrifugal force, thereby effectively suppressing the internal vibration caused by the disc eccentric mass.
