Abstract
A self-compensating balancer for a disk player is provided and includes a supporting plate fixed to a rotating shaft of a spindle motor for supplying rotary power to a disk. Pivot pins are installed in the supporting plate and two or more pendulums are arranged around the supporting plate. The pivot pins and pendulums are linked by connectors, such that upon rotation of the shaft, the connectors are elastically transformed and a centroid of the pendulums faces a centroid of the disk, centered around the rotating shaft of the spindle motor, due to a centrifugal force.
Claims6
A self-compensating balancer for a disk player, comprising:
- a shaft rotated by a spindle motor;
- a supporting plate fixed to the shaft for supporting rotary power to a disk;
- a plurality of pivot pins installed in the supporting plate;
- a plurality of pendulums arranged around the supporting plate;
- and
- a plurality of connectors that respectively connect the plurality of pivot pins to the plurality of pendulums, wherein the plurality of connectors are elastically transformed so that a centroid of the plurality of pendulums faces the centroid of the disk, centered around the rotating shaft of the spindle motor, due to a centrifugal force, during the rotation of the disk.
A turntable combined with a self-compensating balancer for a disk player, comprising:
- a shaft rotated by a spindle motor;
- a seating unit fixed to the shaft and rotated in combination with the shaft, the seating unit having a protrusion to which a central hole of a disk is combined;
- a supporting plate fixed to the shaft so as to be separated from the seating unit by a predetermined distance;
- a plurality of pendulums interposed between the seating unit and the supporting plate such that the pendulums do not interfere with each other;
- a plurality of pivot pins installed between the seating unit and the supporting plate;
- and
- a plurality of connectors, which respectively connect the plurality of pendulums to the plurality of pivot pins, wherein the plurality of connectors are elastically transformed upon rotation of the seating unit so that a centroid of the pendulums faces a centroid of the disk centering around the rotating shaft and thus, an internal vibration caused by an eccentric mass of the disk is prevented.
