Background

The guitar is also called a six-string instrument, is a plucked musical instrument, generally comprises six strings, and is similar to a violin in shape. The guitar plays an important role in both modern and classical music, and is one of the three major instruments in the world.

Generally, a guitar includes parts such as a resonance box, a neck, a bridge, a head, and a peg. The resonance box is an important structural part, and sounds with the same frequency are superposed by utilizing the resonance principle, so that the original sound is enhanced and the sound is produced.

At present, the guitar resonator is mainly formed by bonding plates, and the bonding pieces are numerous and the process is complex. Meanwhile, the bonding mode has uneven stress, stress concentration is easy to occur to cause the deformation of the guitar resonator, and the guitar resonator needs to adopt larger wall thickness to resist the deformation, so that the sound quality of the guitar is adversely affected.

In addition, the adhesive bonding structure can cause adhesive failure, which is particularly serious in a humid environment and is not favorable for maintaining the life of the guitar. The bonding process is also applied to parts such as the neck, and the like, and the problem is the same as that of a guitar resonator.

Specifically, the faceplate 0110 and the first sound beam 0111 are formed by removing materials from the same base material without being adhered by glue. First tone beam 0111 extends to the outside of panel 0110 from panel internal face 0114, connects between first tone beam 0111 and panel internal face 0114 slick and sly, the transition is natural, avoids the appearance of sharp portion.

Because the same base material is naturally connected between the panel 0110 and the first sound beam 0111, the stress of the connecting part of the panel 0110 and the first sound beam 0111 is distributed uniformly and continuously, and stress concentration cannot occur. Even when the wall thickness of the panel 0110, that is, the distance between the panel outer wall surface 0115 and the panel inner wall surface 0114 is small, deformation due to stress concentration does not occur.

Correspondingly, the first reinforcing strip 0112 and the panel 0110 are also formed by removing materials from the same base material without being adhered by glue. Thus, the first reinforcing bar 0112 can further reinforce the structural strength of the guitar resonator 0100 without causing stress concentration.

Under the structure, the wall thickness of the panel 0110 can be greatly reduced, the maximum position can be smaller than 3mm, the problem of stress concentration of the bonding structure is avoided, the integrally formed first sound beam 0111 is also beneficial to exerting a better reinforcing function, and the panel 0110 has good structural strength.

Meanwhile, under a smaller wall thickness, the sensitivity and frequency response of the panel 0110 are better, and the sound conduction between the integrally formed panel 0110 and the first sound beam 0111 is rapid and natural, so that the sensitivity and frequency response range of the guitar resonator 0100 are further enhanced.

Preferably, the first beam 0111 can be in the form of a fan, an X, a grid, etc. Preferably, the first beam 0111 should fill the inner wall surface 0114 of the panel to further increase the strength of the panel 0110 and to enhance the resonance of the guitar resonator 0100.
