DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stringed instrument such as a guitar or a violin (hereinafter, a guitar will be described as an example).
More specifically, the present invention relates to a body of a guitar devised so that a beautiful tone can be produced by improving an acoustic effect.

[0002]

2. Description of the Related Art Conventionally, the body of a guitar has been made of a body obtained by bending a thin plate, a back plate, and a front plate. However, it has been very difficult to produce a beautiful sounding sound. In addition, the materials used were strictly scrutinized using precious timber such as rosewood and hacaranda, and were made over a long period of time using technology and a wealth of knowledge.

[0003]

As described above, in the production of a conventional guitar, it is difficult to select the material used for the body of the guitar. Especially, the most desirable hacaranda is banned from being imported by the Washington Treaty. Distribution was very low. Rosewood is the next most commonly used material, but the country of origin restricts the shipment of logs, making it impossible to produce enough lumber for guitars and selling very few materials. Also, in the material management, a long period of time is required for drying and curing with great care, and in the processing stage, since the work is mainly performed by human hands, various technical skills are required. There was a problem.

Therefore, the development of a guitar body capable of producing a beautiful and resonating sound without using expensive materials or high technical skills has been an issue.

[0005]

Means for Solving the Problems In order to solve the above problems, the present invention takes the following technical means. That is, according to the present invention, in a guitar body provided by covering a front plate 4 on a body 1 composed of a body plate portion 2 and a back plate portion 3, a plurality of lateral grooves 6 or a large number of grooves are provided inside the body plate portion 2. The vertical groove 7 is formed by engraving an inclined groove.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS After a horizontal groove 6 or a vertical groove 7 is provided inside a body plate portion 2, a front plate is stretched, a neck is attached, a coating and parts are attached by the same procedure as in the conventional processing method. ,
Complete the guitar.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. In FIG. 1, reference numeral 1 denotes a body of a guitar. The body 1 is composed of a body plate portion 2 formed by bending into a known shape and a back plate portion 3 provided at the bottom of the body plate portion 2. It becomes. Further, a top plate 4 in which a sound hole 5 is formed is covered on the upper portion of the body 1 just like the body of a conventional guitar. The body plate portion 2 and the back plate portion 3 may be integrally formed without a seam. However, as shown in FIG. 2, the body plate portion 2 and the back plate portion 3 may be separately formed and then provided by bonding. In manufacturing these members, a medium hardness wood such as birch and white ash is used, but plastic, plywood and the like can also be used.

A plurality of lateral grooves 6 are provided around the inside of the above-mentioned body plate portion 2 so that the inside shape of the body plate portion 2 is formed as a whole with irregularities. It has been found that the sound effect improves as the number of 6 increases.

Further, in the present invention, a treble and a bass can be separately formed as by-products.
In other words, in a concave and convex groove part, by making a sharp peak to make a high sound, and by making a low sound into a round peak and a wide valley, by changing the height and shape and width of each valley , So that it can meet the demand of the user.

FIG. 3 shows a second embodiment of the present invention. The present embodiment has a configuration in which a number of vertical grooves 7 are engraved as illustrated in the entire periphery of the inside of the body plate portion 2. Even if it is changed, the same sound effect as the previous embodiment can be exhibited.

Although the example in which the horizontal groove 6 and the vertical groove 7 are provided inside the body plate portion 2 has been described above, in the present invention, the shape of such a groove may be changed to an inclined shape (not shown). Not something.

[0012]

As described above, according to the present invention, by providing a horizontal or vertical groove inside the body of a stringed instrument such as a guitar, a beautiful and sounding sound can be produced. There is an effect that it is possible to produce a high-quality product that can be sufficiently satisfied by the user using the missing material. In addition, there is an advantage that an inexpensive product can be provided because expensive materials and high technical skills are not required.
