Device convenient for tuning guqin tuning peg

Abstract

The invention discloses a device convenient for tuning guqin tuning pegs, and relates to the field of musical instruments. The device solves a problem that at present, guqin tuning needs great effort. The device convenient for tuning guqin tuning pegs is provided with a nut which is a regular polygon prismoid with a center hole. The round sectional area of the center hole of the nut is equal to the round sectional area of the top hole of a tuning item. Area of the upper end face and the lower end face of the nut in the regular polygon prismoid is larger than or equal to the area of the top surface of the tuning item. The device is simple in structure, easy in manufacturing, and ensures range, and saves labor to tune.

Description

technical field [0001] The invention relates to the field of musical instruments, in particular to a device for tuning a guqin. Background technique [0002] As an intangible cultural heritage handed down from ancient times to the present, Guqin is the oldest plucked-string instrument in my country. It has been popular since the time of Confucius and has an important position as the head of the four arts of literati in traditional Chinese culture. In terms of shape, the body of the guqin is glued into a resonating box with the surface and the bottom plate. The surface is tied with seven strings, namely the lyre. The whole guqin is made of paulownia or catalpa wood. The body is about 120 cm long, 20 cm wide and about 6 cm long, 4.4 cm long and 1.5 cm wide; in terms of art, Guqin has a wide and gentle sound range, simple and elegant timbre, rich connotations, and a sense of history. Therefore, it was listed as a piano, chess, calligraphy and painting by scholars in ancient tim...

Problems solved by technology

[0003] Guqin needs to be tuned and tuned according to the different requirements of the melody before each performance, and the tuning and tuning is usually done by using the traditional velvet twisting around the neck of the neck to adjust the pitch and transposition of the sound, so the use of Guqin Zhenzi The frequency is very high, but there are some problems in the tuning and tuning of the Guqin Zhenzi: on the one hand, the tuning is very laborious, because the strings need to be tightened to a certain position to achieve the desired tone, which requires the operator's finger force It is very difficult for women and children to rotate the Guqin under normal circumstances, and it is very difficult to tune the seven strings. Before playing the guqin, it is necessary to ask a tuner or a man to help tune the strings and tune

The second is that the strings are tuned very frequently. Due to the tension of the wool thread on the guqin pillar and the influence of factors such as changes in temperature and humidity, the tightness of the strings connected by the wool thread is always affected, so it is very easy to make the strings loose. The fixed pitch is out of tune, also known as running strings. For example, if the Guqin is tuned in the background and then moved to the foreground, the strings will be loose, and the player still needs to tune the strings and tune again before playing.

[0005] At present, people use the worm wheel and worm gear transmission of the Western musical instrument adjustment button to adjust the pitch on the Guqin. Labor-saving, but whether it is gear transmission or screw transmission, they all need to use metal materials to make gears, nuts, screws and other components to install on the bottom plate and the zither of the guqin, such as the patent No. 201420418405.2 "A Guqin tuning and tuning Qin Zhen device", patent No. 03245441.4 "screw rod Qin Zhen" and patent No. 201320107221.X "Guqin Zhenzi without sound loss" and other patented technologies all use metal parts to be installed on the body or Zhenzi of the guqin. This not only changed the shape of the guqin, but also destroyed the range of the guqin, making the guqin lose its lofty status in the art palace, thus making the guqin lose the traditional meaning of simplicity and elegance
