Filed: 1986-02-06
Abstract: PURPOSE:To enable many persons to enjoy the sound by mounting an acoustic lens on the front surface of respective speaker units, thereby enlarging an area so that the voices from left-hand side and right-hand side speaker systems overlap with each other. CONSTITUTION:The acoustic lenses 6a and 6b are mounted on the left-hand side and the right-hand side speaker units 2a and 2b. As the voice is separated into right and left portions and propagated from the left-hand side and the right-hand side speaker systems 3a and 3b while the users are watching, for instance, a picture on a television receiver 5 of stereoscopic television broadcasting, the voice from the speaker units 2a and 2b are refracted by the lenses 6a and 6b provided ahead of a diaphragm, and hence made overlapping in the area shown by A1O5O4O6B2 in the figure. Accordingly, the persons located within this area can appreciate the stereoscopic television broadcasting with the fixed sound image.
