Abstract

A musical instrument includes a plurality of strings and a body. The body supports the plurality of strings on a first surface of the body. The body includes a groove formed in the first surface that extends linearly. The groove has a constant width and a constant depth.

First claim

What is claimed is:

1. A musical instrument, comprising:
a plurality of strings; and
a body having a top exterior surface and supporting the plurality of strings on a first surface of the body, wherein
the body includes a groove formed in the first surface that extends linearly,
the groove has a constant width and a constant depth,
the groove is configured to adjust a vibration of the body, and
the groove is formed on the top exterior surface of the body.

2. The musical instrument according to claim 1 , wherein the groove extends linearly in a direction that intersects a direction in which the plurality of strings extends.

3. A musical instrument, comprising:
a plurality of strings; and
a body having a top exterior surface and supporting the plurality of strings on a first surface of the body, wherein
the body includes a groove formed in the first surface that extends linearly,
the groove has a constant width and a constant depth,
the groove is configured to adjust a vibration of the body in a direction that intersects a direction in which the plurality of strings extends, and
the groove is formed on the top exterior surface of the body.

4. The musical instrument according to claim 3 , wherein
the body includes a plurality of corner portions, and
the groove is provided for one of the plurality of corner portions that has a natural frequency higher than natural frequencies of other corner portions.

5. The musical instrument according to claim 4 , wherein the one of the plurality of corner portions that has a natural frequency higher than the natural frequencies of other corner portions includes, as the groove: i) a groove extending in a protruding direction of the one of the plurality of corner portions, ii) a groove extending in a direction that intersects the protruding direction, or iii) the groove extending in the protruding direction and the groove extending in the direction that intersects the protruding direction.

6. A musical instrument, comprising:
a plurality of strings; and
a body having a top exterior surface and supporting the plurality of strings on a first surface of the body, and
a first member fitted in a groove formed in the first surface and having stiffness higher than a stiffness of a portion of the body other than the groove, wherein
the groove is formed on the top exterior surface of the body.

7. The musical instrument according to claim 6 , wherein the first member is fixed to the body at a portion of the first member embedded in the groove.

8. The musical instrument according to claim 6 , wherein the first member includes a first stiffness portion shaped like a plate and having stiffness that is higher than a stiffness of the portion of the body other than the groove.

9. The musical instrument according to claim 8 , wherein the first member further comprises a second stiffness portion having stiffness that is lower than a stiffness of the first stiffness portion.

10. The musical instrument according to claim 9 , wherein the first member further comprises a third stiffness portion that is shaped like a plate and having a stiffness that is higher than a stiffness of the second stiffness portion.

11. The musical instrument according to claim 10 , wherein, in a state in which the first member is fitted in the groove, the first stiffness portion and the third stiffness portion sandwich the second stiffness portion therebetween in a direction of depth of the groove.

12. The musical instrument according to claim 11 , wherein, in the state in which the first member is fitted in the groove, the second stiffness portion has a length in the direction of depth of the groove that is larger than a length of the first stiffness portion and a length of the third stiffness portion in the direction of depth of the groove.

13. The musical instrument according to claim 8 , wherein the first stiffness portion is formed of carbon fiber reinforced plastic.

14. The musical instrument according to claim 9 , wherein the second stiffness portion is formed of wood.

15. The musical instrument according to claim 10 , wherein the third stiffness portion is formed of carbon fiber reinforced plastic.

16. The musical instrument according to claim 1 , wherein the groove is formed at a position different from a position of a pickup and a position of a bridge on the first surface.

17. A musical instrument, comprising:
a plurality of strings;
a body supporting the plurality of strings on a first surface of the body, and
a pickguard provided on the first surface, wherein
the body includes a groove formed in the first surface that extends linearly,
the groove has a constant width and a constant depth, and
the groove is covered by the pickguard in a state in which the pickguard is attached to the first surface, and exposed in a state in which the pickguard is removed from the first surface.

18. A musical instrument, comprising:
a plurality of strings;
a body having a top exterior surface and supporting the plurality of strings on a first surface of the body, wherein
the body includes a groove formed in the first surface that extends linearly,
the groove has a constant width and a constant depth, and
the groove is formed at a position where the plurality of strings do not overlap the groove when viewed in a direction orthogonal to the first surface, and
the groove is formed on the top exterior surface of the body.

19. The musical instrument according to claim 1 , further comprising a pickguard provided on the first surface, wherein
the groove is covered by the pickguard in a state in which the pickguard is attached to the first surface, and exposed in a state in which the pickguard is removed from the first surface.

20. A musical instrument, comprising:
a plurality of strings; and
a body supporting the plurality of strings on a first surface of the body, wherein
the body includes a groove formed in the first surface that extends linearly,
the groove has a constant width and a constant depth,
the groove is configured to adjust a vibration of the body in a direction that intersects a direction in which the plurality of strings extends
the body includes a plurality of corner portions, and
the groove is provided for one of the plurality of corner portions that has a natural frequency higher than natural frequencies of other corner portions.

21. The musical instrument according to claim 20 , wherein the one of the plurality of corner portions that has a natural frequency higher than the natural frequencies of other corner portions includes, as the groove:
i) a groove extending in a protruding direction of the one of the plurality of corner portions,
ii) a groove extending in a direction that intersects the protruding direction, or
iii) the groove extending in the protruding direction and the groove extending in the direction that intersects the protruding direction.
