Abstract
A speaker apparatus includes a pair of left and right speaker blocks that respectively have acoustic output sections and that are arranged inside a backrest. The pair of speaker blocks are arranged horizontally side by side relative to a headrest located on a front surface side of the backrest, and at least part of the headrest is located within a range of a nominal directivity angle of acoustics output from the acoustic output sections. This ensures that, of the acoustics output from the acoustic output section of the speaker block on the left side, at least some acoustics that head for the right ear are blocked by the headrest and that, of the acoustics output from the acoustic output section of the speaker block on the right side, at least some acoustics that head for the left ear are blocked by the headrest.
