    • A device for tuning a stringed instrument includes a housing attachable to the instrument, an elongate output shaft extending from within a gear chamber of the housing and having a string spindle on a distal end zone thereof, and an in-line drive gear assembly within the gear chamber for turning the spindle in order to wind a string of the instrument thereabout, thereby adjusting the string tension. The drive gear assembly includes a first reduction gear assembly, operable by turning a first knob, for rotating the spindle in accordance with a first rate of rotation to make coarse adjustments, and a second reduction gear assembly, in-line with the first reduction gear assembly, and operable in conjunction therewith by turning a second knob, thereby rotating the spindle in accordance with a second rate of rotation for fine tuning the instrument.
    • 用于调谐弦乐器的装置包括可附接到所述乐器的壳体,从所述壳体的齿轮室内延伸的细长输出轴,并且在其远端区域上具有弦轴,并且在所述内部驱动齿轮组件内 用于转动主轴的齿轮室,以便将琴弦缠绕在一起,从而调节弦的张力。 所述驱动齿轮组件包括第一减速齿轮组件,所述第一减速齿轮组件可通过转动第一旋钮来操作,用于根据第一旋转速度旋转所述心轴以进行粗调;以及第二减速齿轮组件,其与所述第一减速齿轮 组装,并且通过转动第二旋钮可与其一起操作,从而根据第二旋转速度旋转主轴以微调仪器。
