Chinese lute built-in differential-type tuning mechanism

Abstract

The invention discloses a Chinese lute built-in differential-type tuning mechanism, which comprises tuning pegs, pins, differential mechanisms, string groove two side walls and strings. The differential mechanisms are arranged to inner side surfaces of the string groove two side walls corresponding to the tuning pegs in different directions; a built-in worm external-extending optical axis section of each the differential mechanism is matched with a built-in axial hole of the corresponding tuning peg; the pins radially run through preset pin holes in the tuning pegs and the worms correspondingly; and therefore, the tuning mechanism, which can drive the differential mechanisms to move by adjusting the corresponding tuning pegs, is formed. The differential mechanisms are worm and gear transmission mechanisms respectively, and the mechanism has distinguishing features of large speed reduction ratio and good self-locking capability; such differential transmission facilitates fine adjustment of tension force of each string, and it is easy to realize accurate tuning; and besides, with the help of the differential mechanisms, the strings can be adjusted easily and quickly, a player is allowed to tune the strings quickly and accurately, and it can be ensured that the tuned strings do not loosen for no reason.

Description

technical field [0001] The invention relates to a tuning mechanism of a musical instrument, in particular to a tuning mechanism of a plucked musical instrument, in particular to a built-in differential tuning mechanism for a pipa. Background technique [0002] Pipa is one of the most representative musical instruments of the Chinese nation with a long history. The pipa is a typical plucked stringed musical instrument. It has a wide range, varied timbre, and rich expressiveness. In particular, the overtone it produces ranks first among all kinds of musical instruments in ancient and modern China and abroad. When playing with a high-quality pipa, the treble range is bright and full of rigidity, the middle range is soft and embellished, and the low range has a solid sound quality. The modern pipa is the result of the improvement and design of performers in the past dynasties, and its system has tended to be unified. The common pipa has six phases and twenty-four frets, with tw...

Problems solved by technology

In reality, the string wound at the end of the pole is greatly affected by the temperature and humidity of the environment. It is necessary to adjust the pole in a timely manner to adjust the sound of the string. The existing technology relies on the taper to generate friction to lock the pole. Although the structure is very simple , Practical, but it is a pair of long-standing contradictions with flexible tuning, because it is difficult to achieve precise micro-adjustment if the pin is locked, and it is easy to loosen and change the tone if the pin is not locked
