<P>PROBLEM TO BE SOLVED: To provide a loudspeaker apparatus which has a high effect of a hearing range expansion for obtaining a central sound image normal, gets a natural tone quality without an incongruity, reproduces a high sound pressure, and is miniaturized. <P>SOLUTION: The apparatus is provided with first loudspeaker units 2 and 5 and second loudspeaker units 3 and 6 which are set up approximately symmetrically when they are looked at from a hearing center axis X1-X2. The first loudspeaker units 2 and 5 radiate a sound to an inside direction and reproduce at least a medium range or higher ranges. The second loudspeaker units 3 and 6 radiate the sound to a front neighborhood direction and attenuate a high range. The sound to arrive from the first loudspeaker unit and the sound to arrive from the second loudspeaker unit with regard to a loudspeaker system which is nearer to a hearing position of the front neighborhood direction of one of loudspeaker systems 1 and 4 weaken each other in the medium range. <P>COPYRIGHT: (C)2008,JPO&INPIT |
