一种能提高音高微调准确度的扬琴柱状滚珠
摘要：
本实用新型公开了一种能提高音高微调准确度的扬琴柱状滚珠。包括材质为铝、铜或不锈钢的柱状滚珠本体，本实用新型的主要特点是：柱状滚珠本体的长度中部的径向周圈设有6-12条均布的直条轮齿，直条轮齿的齿顶设为半圆柱形，直条轮齿的齿顶圆直径小于柱状滚珠本体的外径；直条轮齿的长度尺寸设为柱状滚珠本体的长度尺寸的四分之三。本实用新型不仅保持便于在左右滚轴板上移动的优点，还能减小与琴弦的接触面，有利于提高对扬琴的音高进行微调时的准确度。
摘要（英）：

The utility model discloses a can improve dulcimer column ball of pitch fine setting degree of accuracy. The column ball body that is aluminium, copper or stainless steel including the material, the utility model discloses a key feature is: is the radial border at the length middle part of column ball body equipped with 6 12 the vertical bar teeth of a cogwheel of strip equipartition, the tooth top of the vertical bar teeth of a cogwheel is established to semi -cylindrical, and the tip diameter of the vertical bar teeth of a cogwheel is less than the external diameter of column ball body, the length and size of the vertical bar teeth of a cogwheel establishes to three of the length and size's of column ball body quartering. The utility model discloses not only keep the being convenient for advantage that moves on the roller board about, can also reduce with the contact surface of string, the degree of accuracy when finely tuning is favorable to improving to the pitch of dulcimer.
