    • A tone arm damping device which provides damping for both horizontal and vertical vibration forces utilizing a single damping mechanism. A gimbal-type support structure includes first and second rotatable bodies rotated respectively from a fixed shaft and from each other. The second or inner rotatable body has formed therein an annular reservoir of damping fluid. A fluted damping ring, attached through an adjustment mechanism to the fixed shaft, extends into the fluid reservoir. The extent of the damping ring into the fluid and hence the amount of the damping force may be set by the adjustment mechanism.
    • 一种音臂阻尼装置,其利用单个阻尼机构为水平和垂直振动力提供阻尼。 万向型支撑结构包括分别从固定轴和彼此旋转的第一和第二可旋转体。 第二或内部可旋转体在其中形成有阻尼流体的环形储存器。 通过调节机构连接到固定轴的槽形阻尼环延伸到流体储存器中。 阻尼环到流体中的程度以及阻尼力的量可由调节机构设定。
