Abstract: 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.

Abstract: There is provided an imaging apparatus including a first housing mounted with an imaging lens, a second housing mounted with a display, and a connecting portion that connects the first housing and the second housing. The connecting portion includes a first rotation mechanism that makes the second housing openable/closable with respect to the first housing by rotating the second housing around the opening/closing axis, and a second rotation mechanism that, in a case where the second housing is closed by the first rotation mechanism, when a surface of the first housing directly facing the second housing and parallel to the opening/closing axis is denoted as a first accommodation surface, makes the second housing rotatable around a vertical axis perpendicular to the first accommodation surface.

Abstract: There is provided a portable device including a photographing unit, a communication unit configured to transmit an image obtained through photographing by the photographing unit to another portable device managed in association with the portable device each time when photographing is performed, and configured to receive the image transmitted from the other portable device each time when photographing is performed in the other portable device, and a display unit configured to display the image transmitted from the other portable device and received by the communication unit.
