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.

Abstract: A sound output device includes a speaker that outputs sound, a housing that includes a sound introduction hook, the sound introduction hook having an internal space that is formed as a sound introduction space for introducing sound output from the speaker, the speaker being arranged in the housing, and an ear pad portion that is provided to be continuous to the housing, the sound introduction hook including an opening through which sound is emitted toward an ear, the sound introduction hook being to be mounted on a root portion of an auricle from a helix side, the ear pad portion being to be mounted on the root portion of the auricle from an earlobe side.

Abstract: A stable wearing state on an ear is secured. A speaker that outputs sound; a speaker arrangement portion in which the speaker is arranged therein; and a sound guiding pipe in which one end portion is continuous with the speaker arrangement portion and an internal space is formed as a sound guiding space that leads the sound outputted from the speaker are provided, in which an opening that emits the sound toward an ear is formed at the other end of the sound guiding pipe. The sound output apparatus is worn on the ear by sandwiching the outer peripheral portion of the auricle between the sound guiding pipe and the speaker arrangement portion or by the sound guiding pipe so that a stable wearing state on the ear can be secured.

Abstract: Favorable recognizability of audio output from a sound output device and external sound is secured, and discomfort caused in a mounted state is reduced. The sound output device includes: a housing in which a speaker is arranged; and a sound introduction hook in which an internal space is provided as a sound introduction space for introducing audio output from the speaker, one end portion is connected to the housing, and audio introduced through the sound introduction space is emitted through an opening of the other end portion, the sound introduction hook is mounted on a root portion of an auricle, and the other end portion of the sound introduction hook is not in contact with an ear. With this, audio output from the speaker is transmitted to a user via the sound introduction hook, and the sound introduction hook is mounted in a state in which the other end portion having the opening through which audio is emitted is not in contact with the ear.
