[0008] Aspects of the present invention will now be described with reference to Figures 1 to 9. All directional references refer to the x, y, and z directions shown in Figure 1. As shown in Figure 1, the guitar in this embodiment comprises separable large body structures 1, 2, and 3, which together constitute a body structure 4. Furthermore, as shown in Figures 2, 3, and 4, large body structures 1, 2, and 3 have a structure that allows them to be separated into small body structures 1a, 1b, and 1c, 2a, 2b, and 2c, and 3a, 3b, 3c, 3d, and 3e, respectively. Furthermore, parts 5, 6a, 6b, 6c, 7, and 8, and a bridge 9 are provided as connecting parts for the structure, and parts 5, 6a, 7, and 8 may also function as bracing.

[0009] As shown in Figures 3, 8, and 9, the large body structure 3 has a frame 10, side panels 11, support columns 12, and joints 13 and 14. The small body structures 3a and 3b, 3a and 3c, 3b and 3d, 3c and 3e, and 3d and 3e can be assembled using the joints 13 and 14. The support columns 12 and the joints 13 and 14 have holes 15 extending through them in the thickness direction (Z-axis direction) through which fasteners such as bolts or screws can be passed. The positions of these holes 15 coincide with the positions of holes 16 and 17 drilled in the large body structures 1 and 2 when assembled, allowing fasteners such as bolts or screws to be passed through the large body structures 1, 2, and 3 in the thickness direction (Z-axis direction) in Figure 3. Tightening the fasteners applies a compressive force in the thickness direction (Z-axis direction), fixing the large body structures 1, 2, and 3 together. The compressive force exerted by the support columns 12 and the joints 13 and 14 allows the large body structures 1, 2, and 3 to maintain their shape without breaking.

[0010] As shown in Figure 2, small body structures 1a, 1b, and 1c are connected by parts 5, 6a, 6b, and 6c and bridge 9, and can be fixed as a single large body structure 1. Large body structure 1 has holes 16 at positions that coincide with the above-mentioned hole 15 when assembled, and can be fixed to large body structures 2 and 3 by passing fasteners such as bolts or screws through large body structures 1, 2, and 3 in the thickness direction (Z-axis direction). Holes 16 may also be screw holes.

[0011] As shown in FIG. 4, the small body structures 2a, 2b, and 2c are connected by parts 7 and 8 and can be fixed as a single large body structure 2. The large body structure 2 has a hole 17 at a position that coincides with the above-mentioned hole 15 when assembled, and can be fixed to the large body structures 1 and 3 by passing a bolt or screw through the large body structures 1, 2, and 3 in the thickness direction (Z-axis direction) in Figure 3. The hole 17 may also be a screw hole.

[0012] As shown in Figure 2, bridge 9 connects small body structures 1a, 1b, and 1c. As shown in Figure 5, bridge 9 has slide holes 18, and the fixed position of bridge 9 relative to body structure 1 can be moved by passing the slide holes 18 through the parts extending from part 6a. The back side of bridge 9 (the surface that comes into contact with body structure 1 during assembly) has holes 19 for passing strings and holes 20 for holding the ends of the strings. Hole 19 is wide enough to pass the strings through and extends all the way to the front side, while hole 20 is wider than hole 19 and does not extend all the way through. By embedding the ends of the strings in holes 20, bridge 9 and the strings become one unit, making it easy to move the fixed position of bridge 9 relative to body structure 1. This structure makes it possible to adjust the position of the strings when it is necessary to change their position, such as when differences in assembly precision or deformation of the structure due to humidity, temperature, or string tension cause the strings to deviate from their specified positions, making playing difficult.

[0013] As shown in Figure 2, the large body structure 1 has small body structures 1a, 1b, and 1c, and the small body structures 1a, 1b, and 1c are connected by being sandwiched between a component 6 and a bridge 9. However, by sandwiching a piezoelectric element 21 between the large body structure 1 and the component 6, or between the large body structure 1 and the bridge 9, as shown in Figure 6, the adhesion of the element 21 to the large body structure 1 can be increased, and the electrical sound quality obtained from the piezoelectric element 21 can be improved.

[0014] In this embodiment, as shown in Figure 1, the structures can be fixed together by passing fasteners such as bolts or screws through the large body structures 1, 2, and 3 in the thickness direction (Z-axis direction). When providing electrical functionality as an electric guitar, it is best to place the main electrical circuitry in the large body structure 3 from the perspective of sound quality, and the piezoelectric element and electromagnetic pickup in the large body structure 1. In this case, by providing metal plates 22 and 23 on the large body structure 3 and the large body structure 1 as shown in Figure 7, the metal plates 22 and 23 can come into contact and be electrically connected when the body structure is assembled.

[0015] As explained above, in a guitar having the body structure of this embodiment, the body can be separated into multiple structures (large body structures 1, 2, and 3), and each can be further separated into smaller structures (large body structure 1 can be divided into small body structures 1a, 1b, and 1c, large body structure 2 can be divided into 2a, 2b, and 2c, and large body structure 3 can be divided into 3a, 3b, 3c, 3d, and 3e). When assembling, small body structures 1a, 1b, and 1c can be integrated into large body structure 1 using parts 5, 6a, 6b, and 6c and bridge 9, and small body structures 2a, 2b, and 2c can be integrated into large body structure 2 using parts 7 and 8. With support 12, joint 13, and joint 14 at the center, large body structures 1 and 2 and small body structures 3a, 3b, 3c, 3d, and 3e are arranged according to their shapes, and all of the structures can be fixed in place by passing fasteners such as bolts or screws through them in the thickness direction (Z-axis direction).

[0016] In addition, parts 5, 6a, 7, and 8 are used not only as connecting parts but also as bracing, which reduces unnecessary parts and improves sound quality.Furthermore, by using bridge 9 as a connecting part, unnecessary parts are also reduced and sound quality is improved.

[0017] In addition, the strings pass through holes 19 in the bridge 9, and holes 20 hold the ends of the strings, thereby integrating the bridge 9 and the strings, and by passing the connecting part 6d extending from part 6a through the slide hole 18, the fixed position of the bridge 9 relative to the body structure 1 can be moved, and it also functions as a fixed part for the body structure 1.

[0018] In addition, as shown in Figure 7, metal plates 22 and 23 are provided on the large body structure 3 and the large body structure 1, and by tightening the fasteners when assembling the body structure, the compressive force in the thickness direction (Z-axis direction) can be used to bring the metal plates 22 and 23 into contact with each other and electrically connect them.

[0019] Furthermore, by sandwiching the piezoelectric element 21 between the large body structures 1 or between the large body structure 1 and the bridge 9 as shown in Figure 6, the force used to tighten the parts 6a and the bridge 9 during assembly can be used to increase the adhesion of the element 21 to the large body structure 1, thereby improving sound quality.

[0020] The above is a detailed description of the present invention, but the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention. [Explanation of symbols]
