Problems solved by technology

[0003] In order to improve the acoustic quality, the soundboard is usually made of spruce wood. In order to be able to withstand the tension, torsion and pressure brought by the strings for a long time, the soundboard must have a certain hardness and strength, that is, it must have a certain strength. Thickness, under the limitations of the material range and acoustic quality of the current solid wood guitar soundboard, the thickness of the soundboard can no longer be thinner, and the existing solid wood guitar soundboard still has the following deficiencies: first, it has strict requirements on the production materials, It leads to high cost; secondly, it is composed of two solid wood boards with the same thickness, which are symmetrically spliced. Due to the shrinkage and swelling properties of the wood itself, the wood is easy to crack, which also affects the service life of the guitar; The thicker the board is, the greater the defects inside the board will be, and the wood will exchange water and oxygen with the outside world, which will also lead to unstable physical and acoustic properties of the guitar

Embodiment 1

[0025] Such as figure 1 As shown, the solid wood core composite guitar soundboard in this embodiment includes a solid wood core board 11, a surface plate 12 bonded to the upper surface of the solid wood core board 11 and a bottom plate 13 bonded to the lower surface of the solid wood core board 11, wherein the arrow The direction indicates the direction of the wood grain texture, which is the same as the following drawings. It can be seen that the solid wood core board 11 is spliced ​​by three solid wood boards with the same thickness and width. Two pieces of veneer with the same thickness and width are spliced ​​together. The solid wood core board 11, the surface board 12 and the bottom board 13 are all spliced ​​structures. On the one hand, it reduces the requirements for raw materials and reduces the cost of the guitar sound board. It can be seen that the joints of the solid wood core board 11 are just staggered with those of the surface plate 12 and the base plate 13, ther...

Embodiment 2

[0031] Such as figure 2 As shown, the solid wood core composite guitar soundboard in this embodiment is basically the same in structure as the solid wood core composite guitar soundboard in Embodiment 1, including a surface board 22, a solid wood core board 21 and a bottom board glued together from top to bottom. 23. The only difference is that the solid wood core board 21 in this embodiment is made of five solid wood boards with the same thickness and different widths; It is spliced ​​from veneers of the same thickness and width.

Embodiment 3

[0033] Such as image 3 As shown, the solid wood core composite guitar soundboard in this embodiment includes a surface plate 32, a solid wood core board 31 and a bottom plate 33 bonded together from top to bottom, and the solid wood core board 31 is made of two solid woods with the same thickness and uniform width. Boards are spliced ​​together, and the surface plate 32 is formed by symmetrical splicing of two pieces of veneer with the same thickness, and the base plate 33 is formed by splicing two pieces of veneer with the same thickness and uniform width. The solid wood board, the veneer for splicing the surface board 32 and the bottom board 33 are all quarter-cut boards, and the solid wood board and the veneer are all spliced ​​longitudinally according to the direction of the wood grain texture. The difference from Example 1 is that the solid wood core board 31 in this embodiment The direction of the grain of the wood is perpendicular to the direction of the grain of the w...

Abstract

The invention discloses a composite solid-wood-core guitar soundboard. The composite solid-wood-core guitar soundboard comprises a solid wood core board, a top board and a bottom board, wherein the top board is adhered to the upper surface of the solid wood core board; the bottom board is adhered to the lower surface of the solid wood core board; the solid wood core board is formed by splicing more than two solid wood boards which are consistent in thickness; the top board is formed by symmetrically splicing two wood veneers; the bottom board is formed by splicing more than two wood veneers which are consistent in thickness; the thickness of the top board is equal to that of the bottom board. The composite solid-wood-core guitar soundboard, having a three-layer structure consisting of the solid wood core board, the top board and the bottom board, replaces a solid-wood guitar soundboard in the prior art; on one hand, requirements of a guitar soundboard on a manufacturing material are reduced, and the cost is reduced; on the other hand, by virtue of a three-layer lamination structure, splicing seams on different layers are staggered with one another, the mechanical performance and stability of the guitar soundboard are improved, and the service life of the guitar soundboard is prolonged.

Description

technical field [0001] The invention belongs to the technical field of musical instruments, and in particular relates to a solid wood core composite guitar soundboard. Background technique [0002] The guitar soundboard, also called the soundboard, is used to transmit the real-time dynamics of the strings through the air, so it directly determines the timbre of the guitar. [0003] In order to improve the acoustic quality, the soundboard is usually made of spruce wood. In order to be able to withstand the tension, torsion and pressure brought by the strings for a long time, the soundboard must have a certain hardness and strength, that is, it must have a certain strength. Thickness, under the limitation of the material range and acoustic quality of the current solid wood guitar soundboard, the thickness of the soundboard can no longer be thinner, and the existing solid wood guitar soundboard still has the following deficiencies: first, it has strict requirements on the produ...
