Description

Technical Field

[0001] The utility model relates to the technical field of instrument tuning auxiliary equipment, in particular to a guqin tuner. Background Art

[0002] Guqin, as a treasure of traditional Chinese music culture, is deeply loved by people for its unique timbre and charm. However, with the revival of Guqin culture, more and more beginners and enthusiasts have joined the ranks of Guqin performance. They face many technical challenges, the most critical of which is the tuning of Guqin.

[0003] The traditional method of tuning the guqin relies on rotating the pegs and pulling the dragonfly knot (string head) of the string back and forth on the yueshan through the velvet button to adjust the tightness of the string. However, this method has obvious limitations. First, the movement of the string is restricted by the width of the yueshan, and it can usually only move about 8 mm, which limits the range of string adjustment. Secondly, for beginners and children, the stringing and tuning techniques are difficult and not easy to master. Furthermore, if traditional silk strings are used, the strings may gradually loosen over time, requiring frequent re-stringing and tuning, which undoubtedly increases the burden on the performer. In order to solve the above problems, technicians have been exploring new methods for tuning the guqin.

[0004] In recent years, with the development of mechanical technology and precision manufacturing, some new types of guqin tuners have come into being. These tuners achieve precise control of the tightness of the strings by introducing mechanical structures such as screws and sliders. However, the existing guqin tuners still need to be improved in structural design and ease of operation.

[0005] Therefore, we propose a guqin tuner to solve the above-mentioned problems. Utility Model Content
