## Abstract

An earphone housing includes an inserter to be inserted into an outer ear hole, and a main body to be coupled to the inserter. The main body includes a bottom surface to contact a surface of a cavum concha, and a side surface to contact a tragus and an antitragus. The side surface includes a depressed part depressed inward and contacting a top of the antitragus, and the side surface contacts the tragus at a part other than the depressed part.

## Claims

### Claim 1

An earphone housing comprising:
an inserter that is configured to be inserted into an outer ear hole of an ear of a user; and
a main body that is coupled to the inserter, wherein:
the main body includes:
a bottom surface that is configured to contact a surface of a cavum concha of the ear; and
a side surface that is configured to contact a tragus of the ear and an antitragus of the ear;
the side surface includes a depressed part that is depressed inward and is configured to contact a top of the antitragus, and
the side surface is configured to contact the tragus with a part other than the depressed part.

### Claim 2 (depends on 1)

The earphone housing according to claim 1, wherein the depressed part is provided in half a circumference or more of the side surface in a circumferential direction of the side surface.

### Claim 3 (depends on 2)

The earphone housing according to claim 2, wherein, of the depressed part, in the circumferential direction, a first end that is configured to be arranged near the tragus at a time of wearing is deeper than a second end.

The earphone housing according to claim 3, wherein a depth of the depressed part is gradually shallower from the first end toward the second end.

### Claim 5 (depends on 1)

The earphone housing according to claim 1, wherein the main body further includes:
a coupler including the side surface and contacting the inserter; and
a protrusion including the bottom surface, coupled to the coupler on a side opposite to a part coupled to the inserter, and configured to protrude toward an outside of the ear.

### Claim 6 (depends on 5)

The earphone housing according to claim 5, wherein the protrusion includes an operator that is configured to receive an operation by the user.

### Claim 7 (depends on 1)

The earphone housing according to claim 1, wherein the inserter is coupled to a part of the main body other than a center of the bottom surface of the main body.

### Claim 8 (depends on 1)

The earphone housing according to claim 1, wherein the bottom surface of the main body has an elliptical shape.

### Claim 9 (depends on 1)
