PURPOSE:To remove an intermediate omission phenomenon during a stereo reproduction by constituting of two planes, providing the plane characteristic to obtain a mirror feature of light and providing a reflecting object excellent in the acoustic reflection having less reflection loss in a high key area. CONSTITUTION:A pair of right and left speakers 5, 6 are disposed in the areas 3, 4 divided by a center area 2 determined by a listener assumed position 1. There is provided the reflecting object 7 constituted of the two planes, having the plane characteristic and excellent in the acoustic reflection having less reflection loss in the high key. The reflecting object 7 is situated in front of the listener and the front area 8 for the listener disposed between the speakers 5, 6, thereby, at the position 1, in addition to the sound of the speakers 5, 6 of the right and left sides, a right and left synthesized sound are received from the direction of the reflecting object 7. Thereby, the intermediate omission phenomenon during the stereo reproduction can be removed, the reflected sound at the head can be listen and various visual problems can be improved.
