摘要

An audio output apparatus has a simplified structure and is stably fitted in an ear assuredly. The audio output apparatus includes: a speaker that outputs a sound; a base body that includes a facing surface and is at least partially inserted into an ear canal of an ear; a rotating body that includes a relative surface at least partially facing the facing surface and is rotatable relative to the base body; and a fulcrum shaft that is present at least at one of a position displaced from a middle portion of the facing surface or a position displaced from a middle portion of the relative surface, the fulcrum shaft serving as a fulcrum of rotation of the rotating body relative to the base body, in which, in a state where the base body is inserted into the ear canal, the rotating body rotated relative to the base body is allowed to be in contact with part of the ear.

說(shuō)明書

The audio output apparatus according to any one of (1) to (6), in which

the rotating body includes a circumferential surface whose one end is continuous with an outer periphery of the relative surface, and

the circumferential surface is formed into a curved surface.

(8)

The audio output apparatus according to any one of (1) to (7), in which

the base body is formed in a tapered shape whose outer circumference becomes smaller as the base body is farther away from the rotating body.

(9)

The audio output apparatus according to (8), in which

the base body is formed in a substantially conical shape.

(10)

The audio output apparatus according to (8) or (9), in which

an outer surface of a tip side portion of the base body is formed in a curved shape convex toward the tip side.

(11)

The audio output apparatus according to any one of (1) to (10), in which

the base body includes an enclosure and an earpiece, the enclosure including a placement space that is formed inside the enclosure, the earpiece being in close contact with at least part of an outer surface of the enclosure, and

the earpiece includes an elastically deformable material.

(12)

The audio output apparatus according to (11), in which
