Description

Technical Field

[0001] The utility model relates to the technical field of guitar manufacturing, in particular to a guitar sound beam structure and a guitar. Background Art

[0002] China is the world's largest guitar producer. Currently, guitar tops generally use an X-shaped bracing structure. While this bracing structure is simple, it somewhat inhibits the top's longitudinal vibration, which is crucial for the clarity and range of a guitar's sound. Furthermore, the X-shaped bracing structure provides insufficient support in the bridge area, causing the top to bulge under the tension of the strings, significantly shortening the guitar's lifespan and severely affecting its performance. Besides the X-shaped bracing structure, there's also a crisscross bracing structure. While this structure provides some support in the bridge area, it also affects the top's longitudinal vibration, thus affecting the guitar's sound quality. Furthermore, this crisscross structure increases the production process complexity, making it unsuitable for mass production. Summary of the Invention

[0003] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of this utility model is to provide a guitar sound beam structure and a guitar with a simpler structure while taking into account the support strength of the panel and the sound quality. The technical solution of this utility model is as follows:

[0004] A guitar sound beam structure comprises: a panel, a first main sound beam, a second main sound beam, a cross beam, and an oblique beam disposed on the panel; the panel having a sound hole; the first main sound beam and the second main sound beam being disposed on either side of the sound hole, the lower extensions of the first main sound beam and the second main sound beam intersecting, and the first main sound beam and the second main sound beam forming the same angle with the central axis of the panel;

[0005] The crossbeam is arranged horizontally and passes through the center point of the panel, and the two ends of the crossbeam are respectively connected to the first main sound beam and the second main sound beam; the oblique beam is arranged on the panel, and the oblique beam is located between the crossbeam and the sound hole, and the two ends of the oblique beam are respectively connected to the first main sound beam and the second main sound beam.

[0006] Furthermore, one side of the top of the panel has a notch.

[0007] Furthermore, the sound hole interface is wavy and gradually shrinks at both ends, the end of the sound hole close to the missing corner is tilted downward, and the axis of the inclined beam is parallel to the center line of the sound hole.

[0008] Furthermore, it also includes a first wing beam and a second wing beam, the first wing beam and the second wing beam are symmetrically arranged and are respectively located on the outside of the first main sound beam and the second main sound beam, one end of the first wing beam is connected to the first main sound beam, and one end of the second wing beam is connected to the second main sound beam.

[0009] Furthermore, outer ends of the first spar and the second spar are inclined downward.

[0010] Furthermore, the extension lines of the outer ends of the first spar and the second spar respectively point to the two side corners of the lower end of the panel.

[0011] A guitar comprises the above-mentioned sound beam structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This structure supports the entire panel in both the horizontal and vertical directions, providing enhanced support in the stress-bearing areas of the panel. Its structure is simpler than other designs, minimizing the negative impact of the beam on vibration, allowing the panel to vibrate more fully and effectively preventing excessive bulging or sagging.

[0017] To facilitate a better understanding of the purpose, structure, features, and efficacy of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that the features shown in the drawings are not necessarily drawn to scale.

[0019] like Figure 1 As shown, this embodiment provides a guitar sound beam structure, comprising: a panel 1, a first main sound beam 2, a second main sound beam 3, a cross beam 4, and an oblique beam 5 arranged on the panel 1; the panel 1 has a sound hole 101, and the sound hole 101 is located in the upper middle position of the panel 1;

[0020] The first main sound beam 2 and the second main sound beam 3 are arranged on both sides of the sound hole 101. The extension lines of the lower sides of the first main sound beam 2 and the second main sound beam 3 intersect, and the first main sound beam 2 and the second main sound beam 3 have the same angle with the central axis of the panel 1. This nearly vertical arrangement of the two main sound beams allows the two main sound beams to bear most of the tension of the strings. In the longitudinal direction, only two main sound beams at a certain angle provide support, which makes the longitudinal vibration of the panel 1 more sufficient, so that the guitar can obtain a clearer and more pleasant sound, thereby improving the sound quality of the guitar.

[0021] The crossbeam 4 is arranged horizontally and passes through the center point of the panel 1. The two ends of the crossbeam 4 are respectively connected to the first main sound beam 2 and the second main sound beam 3; the oblique beam 5 is arranged on the panel 1, and the oblique beam 5 is located between the crossbeam 4 and the sound hole 101. The two ends of the oblique beam 5 are respectively connected to the first main sound beam 2 and the second main sound beam 3;

[0022] The triangle-based structure is a simple and stable structural model. The first main sound beam 2, the second main sound beam 3, the cross beam 4 and the oblique beam 5 form a triangular structure similar to an inverted "A" shape. This structure supports the strength of the entire panel 1 in both the horizontal and vertical directions. Through this improvement, the stress-bearing area of ​​the panel 1 is strengthened. At the same time, its structure is simpler than other structures, which minimizes the negative impact of the sound beam on the vibration, makes the vibration of the panel 1 more sufficient, and effectively prevents the panel 1 from excessive bulging or sagging.

[0023] In addition, since the sound beam of this structure is simple in structure, without crossing and splicing, the process is simple, the production efficiency is improved, and it is more conducive to mass production in the factory.

[0024] In this embodiment, the panel 1 is applied to a guitar with a cutaway corner 102 , and thus one side of the top of the panel 1 has a cutaway corner 102 . Due to the shape of the cutaway corner 102 , a portion of the upper end of the first main sound beam 2 needs to be cut off, and the total length of the first main sound beam 2 is smaller than that of the first main sound beam 2 .

[0025] As a preferred solution, the interface of the sound hole 101 is wavy and tapers at both ends. The end of the sound hole 101 close to the notch 102 is tilted downward, so that the panel 1 has an aesthetically pleasing shape; the axis of the inclined beam 5 is parallel to the center line of the sound hole 101, which is conducive to adapting to the shape of the sound hole 101 and providing better support for the panel 1.

[0026] As a preferred solution, it also includes a first wing beam 6 and a second wing beam 7, the first wing beam 6 and the second wing beam 7 are symmetrically arranged and are respectively located on the outside of the first main sound beam 2 and the second main sound beam 3, one end of the first wing beam 6 is connected to the first main sound beam 2, and one end of the second wing beam 7 is connected to the second main sound beam 3; the two wing beams also increase the strength of the panel 1 to a certain extent. The more important function of the two wing beams is to diffuse the vibration of the panel 1, making the vibration of the panel 1 fuller. In addition, due to the existence of the wing beams, the mass distribution of the entire panel 1 is more uniform, so that the amplitude of the panel 1 is more uniform and regular when vibrating, thereby improving the sound quality.

[0027] Furthermore, the outer ends of the first spar 6 and the second spar 7 are tilted downward. Preferably, the extension lines of the outer ends of the first spar 6 and the second spar 7 point to the two side corners of the lower end of the panel 1 respectively.

[0028] This embodiment also provides a guitar with the above-mentioned sound beam structure.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
