Abstract
An acoustic device includes: a base; a shaft member penetrating through the base; a turntable provided on the base, the turntable being rotatable around the shaft member; a movable member movable along the shaft member; and a load adjuster attached to the shaft member, the load adjuster configured to approach the turntable along the shaft member and press an intervening member interposed between the load adjuster and the movable member toward the turntable to adjust a rotation load of the intervening member against the turntable, in which the load adjuster is configured to attract the movable member by magnetic force to hold the intervening member together with the movable member.
Claims8
An acoustic device comprising:
- a base;
- a shaft member penetrating through the base;
- a turntable provided on the base, the turntable being rotatable around the shaft member;
- a movable member provided in a manner movable along the shaft member;
- and
- a load adjuster attached to the shaft member, the load adjuster being configured to approach the turntable along the shaft member and press an intervening member interposed between the load adjuster and the movable member toward the turntable to adjust a rotation load of the intervening member on the turntable, wherein
- the load adjuster is configured to attract the movable member by a magnetic force to hold the intervening member together with the movable member.
An acoustic device comprising:
- a turntable having a placement surface on which a disc is placeable, the turntable being rotatable together with the disc;
- a shaft member penetrating through the turntable;
- a movable member having a contact surface capable of contacting with the disc, the movable member being provided in a manner movable along the shaft member;
- and
- a load adjuster attached to the shaft member, the load adjuster being configured to approach the turntable along the shaft member and press the disc interposed between the load adjuster and the movable member toward the turntable to adjust a rotation load of the disc on the turntable, wherein
- the turntable is rotatable around the shaft member,
- the load adjuster is configured to attract the movable member by a magnetic force to hold the disc together with the movable member, and
- the movable member is movable between a first position, at which the contact surface is located opposite the load adjuster with respect to the placement surface, and a second position, at which the contact surface is located near the load adjuster with respect to the placement surface.
