Abstract
An optical disk player wherein a chassis having an optical pickup, a disk table and the like mounted thereon is supported by a frame using elastic support means at a plurality of positions, a vessel filled with a viscous fluid and sealed is provided at either the frame or the chassis, and a movable member provided at the other of the two is arranged in the sealed viscous fluid. With this arrangement, the slope of the Q curve in the resonant region is moderate enough to improve the antivibration characteristics, thus substantially eliminating sound omissions.
Claims3
An optical player having a chassis on which an optical pick-up and a disk table are mounted, a plurality of elastic support means resiliently supporting the chassis on a frame for making said chassis displaceable relative to said frame in all directions, and vibration absorbing means for absorbing vibrations from said frame, said vibration absorbing means comprising:
- a rod horizontally projecting from one of said chassis or said frame, and
- a vessel made of rubber, filled with silicone oil and thereafter sealed, said vessel having a hollowed interior portion horizontally and inwardly extending and surrounded by silicone oil to form a central hole for receiving said rod, and a bellows forming the outer periphery of said vessel, and said vessel having a flange which is fixed to the other of said chassis or said frame, whereby said rod is movable in said silicon oil in all directions together with said hollowed interior portion.
