Abstract
There is provided an audio output apparatus capable of providing an effect, with a limited number of speakers, as if the person displayed on the display screen is really speaking. When the television conference is started with a communication partner through a set top box, the image of the communication partner is displayed on the image displaying reflective plate. At the same time, ultrasonic waves superposed with the voice of the partner are emitted from a left speaker and a right speaker. The sound emitting directions of the left and right speakers are directed toward the image displaying reflective plate on which the partner is displayed. The ultrasonic waves emitted from the left and right speakers are reflected by the reflective plate and proceed toward the listener who can hear the voice of the partner as if the voice is directly emitted from the reflective plate.
