Guitar chord fingering device and guitar provided with same

Abstract

The invention provides a guitar chord fingering device. The guitar chord fingering device comprises a shell, a frame, a plurality of electromagnetic devices, string contact pressers and an electrical control unit, wherein the shell is provided with chord keys; the frame is fixedly arranged in the shell; the electromagnetic devices are fixedly arranged on the frame; each electromagnetic device corresponds to a different pitch of each string of a guitar; the string contact pressers are driven by the electromagnetic devices; the chord keys are electrically connected with the electrical control unit; and the electrical control unit controls the electromagnetic device at the corresponding pitch to move according to a chord fingering spectrum corresponding to the chord keys so as to drive the string contact pressers to press strings. The invention also provides the guitar provided with the guitar chord fingering device. The guitar chord fingering device and the guitar have the advantages of good universality, simple structure and capability of avoiding interference among parts in various chord processes.

Description

technical field [0001] The invention relates to the field of stringed instrument accessories and the field of stringed instruments, in particular to a guitar chord fingering device and a guitar equipped with the guitar chord fingering device. Background technique [0002] Guitar is a very popular instrument around the world, and when playing, it is often necessary to play chords. However, there are nearly 360 fingerings from A to G on the chord fingering spectrum, and more than a dozen are frequently used, and in each chord fingering, different fingers are required to press different grades on different strings, and Guitars generally have twelve or fourteen grades, which need to be changed when playing, which brings great difficulties to guitarists, especially beginners. Moreover, frequent pressing of the strings can cause pain in the fingers. [0003] In the Chinese utility model patent with the application number 91220091.X filed on July 20, 1991, with the theme of "guit...

Problems solved by technology

[0006] However, when playing, it is often encountered that different chords need to depress the same fret of the same string, for example, C, C+, C-B, C6, C7 and other chords all need to depress the second fret fourth string, That is to say, for one string, multiple long-fingered keys need to be set at the same fret, or multiple main control levers need to be moved to the same sub-control lever

The above-mentioned patents all adopt a purely mechanical structure, which will make the whole structure very complicated, and the more chord keys are set, the more complicated the structure will be. Interference between the long finger keys and the main control bar will inevitably occur, and there is a limit for each grade of the guitar. As far as t
