Description

The present invention relates to a device for improving the sound of a guitar (hereinafter referred to as a device).

Guitars with a wooden sound board and sound hole, which are a type of stringed instrument, include classical guitars and acoustic guitars.

As shown in FIG. 7, in a classical guitar, a saddle 21 for stretching a string 17 is fitted in a groove of a bridge 22 fixed to a surface plate 20. After hanging the string 17 on the saddle 21, pass it through the hole of the bridge 22, straddle it and dive under the string 17 between the saddle 21 and entangle the tip on the upper surface of the bridge 22 so that the string 17 does not come off. To fasten. (Hereafter referred to as string fastening)

On the other hand, as shown in FIG. 8, in the acoustic guitar, a saddle 21 for stretching the string 17 is fitted in the groove of the bridge 22 fixed to the surface plate 20 in the same manner. The string 17 is provided with a ball end 18 at its tip, and after passing the ball end 18 through the hole of the bridge 22, the bridge pin 19 is inserted into this hole and the string is fastened.

As mentioned above, the classical guitar is a method in which the tip of the string 17 is submerged under the string 17 between the saddle 21 and the bridge 22 and entwined on the upper surface of the bridge 22 to fasten the string. A force acts in the direction of lifting by itself, causing a minimum amount of looseness and reducing the sound quality. The classical guitar has a drawback that a clear sound cannot be produced due to such a physical factor, and there is "Patent Document 1" as a prior art for solving this problem.
However, as shown in FIG. 8, the acoustic guitar does not have a structural defect that lowers the sound quality as in the classical guitar.
