Abstract

A body structure of an electric guitar includes a body including a first chamber and a second chamber formed spaced apart from each other, and a slit that connects the first chamber and the second chamber.

First claim

What is claimed is:

1. A body structure of an electric guitar, comprising:
a body comprising a top member and a back member that overlap to form the body, the back member comprising:
a first chamber;
a second chamber spaced apart from the first chamber; and
a slit that connects the first chamber and the second chamber to each other,

wherein the first chamber, the second chamber, and the slit do not open to outside of the body in a state where the top member overlaps with the back member to form the body, and
wherein the first chamber and the second chamber are formed in a region of the body other than regions to which a neck, a bridge, electromagnetic pickups, and controllers are attached, when viewed from a thickness direction of the body.

2. The body structure of the electric guitar according to claim 1 , wherein a cross-sectional area of the slit taken along a direction orthogonal to an arrangement direction of the first chamber and the second chamber is smaller than a cross-sectional area of the first chamber and a cross-sectional area of the second chamber taken along the direction orthogonal to the arrangement direction.

3. The body structure of the electric guitar according to claim 1 , wherein a ratio of a volume of the second chamber to a volume of the first chamber is 70% or more and 130% or less.

4. The body structure of the electric guitar according to claim 1 , wherein the body comprises a plurality of slits connecting the first chamber and the second chamber to each other.

5. The body structure of the electric guitar according to claim 1 , further comprising a sound absorbing material disposed in the slit.

6. An electric guitar comprising the body structure according to claim 1 .

7. The body structure of the electric guitar according to claim 1 , wherein the top member has a first thickness and the back member has a second thickness greater than the first thickness.

8. The body structure of the electric guitar according to claim 7 , wherein the first chamber is a first recessed portion of a front surface of the back member that faces the top member, and the second chamber is a second recessed portion of the front surface of the back member that faces the top member.

9. The body structure of the electric guitar according to claim 8 , wherein the slit that connects the first chamber and the second chamber to each other is a third recessed portion of the front surface of the back member that faces the top member.

10. The body structure of the electric guitar according to claim 9 , wherein a depth of the third recessed portion equals a depth of the first recessed portion and a depth of the second recessed portion.

11. The body structure of the electric guitar according to claim 9 , wherein a depth of the third recessed portion is less than a depth of the first recessed portion and a depth of the second recessed portion.
