Audio output system and method therefor
First Claim
1. An audio output system comprising:
- an image display unit having a screen for displaying an image;
a reflective member provided on the screen of said image display unit and adapted to reflect sound waves; and
a plurality of speakers, each speaker generating an ultrasonic sound wave corresponding to an audio signal and said audio signal synchronized with said image;
wherein said speakers are capable of selectively turning between a first position where the sound wave generated by the respective speaker is reflected by said reflective member and is transmitted to a listener at a position opposed to the screen of said image display unit, and a second position where the sound wave generated by the respective speaker is output directly toward the listener.

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.

7. An audio output method comprising the steps of:
-
utilizing an image display unit provided with a reflective member, for reflecting an ultrasonic sound wave, on a screen for displaying an image;
selectively turning a plurality of speakers between a first position for reflecting the ultrasonic sound waves corresponding to audio signals generated from the plurality of speakers using said reflective member and transmitting said sound waves to a listener at a side opposed to the screen of said image display unit, and a second position for transmitting the sound waves from the plurality of speakers directly to the listener, wherein the audio signals are synchronized with said image. - View Dependent Claims (8, 9, 10, 11, 13, 15)
