Description

String adjusting device for guqin

Technical Field

The utility model belongs to musical instrument accessory field, concretely relates to string adjusting device of guqin.

Background

With the increase of the lovers of the guqin, the user can face the problems of tuning, changing strings and the like.

At the position of the nine emblems on the surface of the violin, two feet which support the violin body and tie strings are provided, which are called goose feet. Because of the bearing force, goose feet are made of solid wood, and because the strings are tied, the wedge seam with the bottom plate must be tight and firm. The goose foot position needs to be kept about 4 centimeters wide or more, and the goose foot with too small area is not easy to fix and is easy to be askew. Yue mountain, the name of the musical instrument part, means the horizontal bar for supporting the strings on the forehead of the Chinese musical instrument.

One end of the guqin string is fixed on the goose foot, and the other end of the guqin string is connected to the tuning device through the mountain.

The qin zhen as the traditional tuning mode has a narrow tuning range. When the string is wound, the string is easily broken due to overlarge unit time momentum, and the string is extremely difficult to operate for people with poor force precision control. Meanwhile, the friction force of the piano strings decreases gradually along with the time lapse, and the phenomenon of tone accuracy slide due to the sudden relaxation of the strings is easy to occur during playing.

The existing tuning design of a peg or a button mode changes the traditional appearance of the guqin to adapt to a new tuning device, and then the guqin cannot be used on the traditional guqin. Or the string instrument needs to be adjusted by a matched special tool, and has strict requirements on the shape of the string instrument and low compatibility.
