Abstract

The present technology is to improve usability. Provided is an attachment portion which includes a first pressing portion and a second pressing portion to be pressed against both surfaces of an auricle respectively and is attached to an ear in a state of sandwiching the auricle. A pair of the attachment portions is provided, and the pair of attachment portions can be engaged with each other. With this structure, the pair of attachment portions can be engaged with each other when not in use and the like, entanglement between cords or between the cords and the attachment portions can be prevented, and usability can be improved.

Claims (12)

1. An audio device attached to an ear, comprising:

an attachment portion that has a first pressing portion and a second pressing portion, wherein the first pressing portion and the second pressing portion are each formed at an end portion of the attachment portion, wherein the first pressing portion and the second pressing portion face each other, wherein the attachment portion has a space for relative insertion of the ear between the first pressing portion and the second pressing portion, wherein a gap between the first pressing portion and the second pressing portion is narrower than an inner width of the space, wherein the first pressing portion and the second pressing portion of the attachment portion are brought into a state of contacting and being pressed against both surfaces of the ear respectively, wherein the audio device is brought into a state in which an external acoustic aperture is not closed, and wherein a sound guiding space formed inside the attachment portion guides sound output from a speaker in the first pressing portion to a sound hole in the second pressing portion.

2. The audio device according to claim 1 , further comprising:

an opening, wherein sound is emitted from the opening in a state of not contacting the ear.

3. The audio device according to claim 1 , wherein the first pressing portion and the second pressing portion are configured to be pressed against both surfaces of an auricle of a user.

4. The audio device according to claim 1 , wherein an opening that emits sound is provided on the second pressing portion.

5. The audio device according to claim 1 , wherein the attachment portion includes an intermediate portion between the first pressing portion and the second pressing portion.

6. The audio device according to claim 5 , wherein a maximum thickness of the first pressing portion and the second pressing portion in a longitudinal direction is thicker than a maximum thickness of the intermediate portion in the longitudinal direction.

7. The audio device according to claim 6 , wherein the intermediate portion hardly contacts the ear of a user in a state in which the audio device is attached to the ear.

8. The audio device according to claim 1 , wherein an outer surface of the attachment portion is a curved surface.

9. The audio device according to claim 1 , wherein a length from the first pressing portion to the second pressing portion is an entire length of the audio device.

10. The audio device according to claim 1 , wherein a surface of each of the first pressing portion and the second pressing portion in contact with the ear is formed in a curved surface projecting outward.
