Abstract
An output section, consisting of a pair of loudspeakers disposed adjacently to each other, is installed inside a seatback of a designated seat. Sound output surfaces of respective loudspeakers face a designated person sitting on the designated seat. It is hence easy to secure a required distance for obtaining clear acoustic image localization in accordance with the size of loudspeakers cooperatively constituting the output section.
