<P>PROBLEM TO BE SOLVED: To perform audio reproduction having overflowing presence by actually moving a speaker in accordance with a sound image. <P>SOLUTION: An image displayed on a monitor 11 is an image in which a train moves from the right side of a screen to the left side while sounding steam whistles. Thus, a viewer can actually feel a sound image of a steam whistle with overflowing presence. Since the whistle can be heard even from a right outside of the actual screen, in a viewing space, the sound generation position of a virtual sound source moves from an A point to a B point in a simulative manner. Therefore, the speaker 13 is moved from an A1 point to a B1 point. <P>COPYRIGHT: (C)2009,JPO&INPIT |
