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 the layout space is concerned, it is impossible to allow many long-fingered keys or master control levers to be arranged at the same time, which causes the fingering instrument to be able to play at most a dozen major chords at the same time, and to meet more performance requirements. It can only be achieved by replacing the fingering device or replacing the main control lever
[0007] In addition, for some chords with a large grade span, such as some chords used on the piano, if they are played on the guitar, the finger span must be very large, which is also very difficult for professional guitar players, and the large span Playing chords can cause harm to the body, and many professional guitarists even develop finger deformities as a result.

Embodiment Construction

[0047] Next, specific embodiments of the present invention will be further described in detail with reference to the accompanying drawings.

[0048] From figure 1 It can be seen that for the fourth string, only in the C part of the chord fingering spectrum, there are 15 chord fingerings such as C, C+, C-B, C6, and C7 that need to be pressed down at the second fret. With technology, it is necessary to set 15 main control levers at the second fret of the fourth string to toggle the auxiliary control levers, or set 15 long-finger keys or short-finger keys here, if you add A-F In other fingerings, if other strings are pressed down at the second fret, a large number of long and short finger keys are required in the prior art, or multiple master control rods are arranged at the second fret at the same time, and It is basically impossible to ensure that there will be no interference between them, so generally only a small number of chord keys can be arranged on the guitar fingering ...

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...
