A middle tree 131 is provided at the tip of the rod 130, the middle tree 131 inserts a through hole 114 of the body 110, and the middle tree tip 132 projects to the outside of the body 110.

FIG. 4 is a cross-sectional view (perspective view) of BB in the modified example 100A of the shamisen. A plate 160 is fixed to the bottom surface of the body 110 instead of the vibrating body 150. The plate 160 is thinner than the thickness of the peripheral wall of the body 110.

A sound hole 161 is formed in the substantially center of the plate 160, and the sound hole 161 is substantially circular.

The vibration wave of the vibrating body 140 is reflected inside the body 110, and a “body ringing sound” is generated. With the conventional shamisen, it was not easy to improve the sound quality of the "body ringing sound", but in the shamisen of the present invention, by providing the complementary member 120 inside the body 110, the acoustic characteristics of the "body ringing sound" can be improved. It is possible to improve.

The complementary member 120 shown in FIG. 4 has a recess 124 formed in a substantially central portion. The side surface of the complementary member 120 is provided with a substantially chevron-shaped recess 124 on an inclined surface, and has a shape close to a dogleg shape (substantially doglegged shape).

With this sound hole 161 it becomes possible to insert a fingertip inside the body 110, and the complementary member 120 can be freely attached and removed.
It can be attached and detached, but in that case, the complementary member 120 and the body 110 are connected by using a magic tape, a magnet, or the like.
In order to be able to attach it detachably, it is necessary that the complementary member 120 and the vibrating body 140 are not glued.

FIG. 5 is a cross-sectional view (perspective view) of BB in the modified example 100B of the shamisen. The complementary member 120 here has a recess 124 in a substantially central portion as described above, and has a shape close to a C shape (substantially C-shaped shape).

As shown in the figure, a vibrating body 151 having a size covering the sound hole 161 is attached. By vibrating the vibrating body 151, it becomes possible to generate a "body ringing sound" having a different taste.

FIG. 6 is a cross-sectional view taken along the line BB in the modified example 100C of the shamisen. As shown in the figure, the complementary member 120 has a recess 124 in a substantially central portion as described above, and has a shape close to a U shape (substantially U-shaped shape).

FIG. 7 is a cross-sectional view taken along the line BB in the modified example 100D of the shamisen. As shown in the figure, the reflective wall portion 123 of the complementary member 120 has corrugated irregularities. A step 125 is formed between the individual wave shapes and the wave shapes.

FIG. 8 is a cross-sectional view taken along the line BB in the modified example 100E of the shamisen. As shown in the figure, the reflective wall portion 123 of the complementary member 120 has stepped irregularities (block-shaped irregularities). A step 125 is formed between the individual blocks.

FIG. 9 is a cross-sectional view taken along the line BB (a perspective view excluding the vibrating body 140) in the modified example 100F of the shamisen. As shown in the figure, a second complementary member 170 is provided inside the body 110.

The second complementary member 170 has a reflective wall portion 175. At least one recess 173 is formed in the second complementary member 170, and a through hole 174 through which the middle tree 131 can pass is also formed.
The second complementary member 170 can also be attached and detached in the same manner as the complementary member 120. In that case, the second complementary member 170 and the body 110 are connected by using a magic tape, a magnet, or the like. For that purpose, the top surface 171 needs to be in a state where it is not glued to the vibrating body 140.

The top surface 171 of the second complementary member 170 and the oral 111 are located on substantially the same plane. By extending the top surface 171 to the glued portion of the vibrating body 140, the vibrating body 140 and the body 110 are less likely to come off. The second complementary member 170 also serves to increase the strength of the body 110.

Various types of the shape of the reflective wall portion 175 are possible. A corrugated groove may be provided as in the complementary member 120 in FIG. 7, and a stepped (block type) groove may be provided as in the complementary member 120 in FIG. A convex portion may be provided instead of the concave portion 173.

The shamisen shown in FIGS. 1 to 9 was a shamisen having a Nakagi 131, but the shamisen is not limited to this mode.
Of course, the effect of the present invention can be obtained even when the rod 130 and the body 110 are directly connected by an adhesive, metal fittings, or the like.

As a method of joining the vibrating body 140 to the complementary member 120 and the body 110, a method of fastening with screws, nails, or studs, or a method of fastening with glue or an adhesive is possible. Furthermore, it is also possible to fasten it with an adhesive and then with a stud.
As a result, the adhesive force between the vibrating body 140 and the body 110 is improved. It is also possible to enhance the decorativeness through studs and the like.

Of course, it is also possible to mount the second complementary member 170 in the body 110 shown in FIGS. 7 and 8.
In that case, the internal structure of the body 110 can be given a sense of unity by forming the groove of the step 125 of the complementary member 120 so as to extend and connect to the reflective wall portion 175 of the second complementary member 170.

By aligning and integrating the side surfaces of the complementary member 120 and the second complementary member 170 shown in FIG. 9, it is possible to surround the inside of the body 110 all around.
As a result, the body 110 can be further strengthened.
