Study on loudspeaker array and its ways of application

The characters of several arranged loudspeakers on an infinite barrier plate are analyzed. Its ways of application are presented by making best use. One of the most important solutions is to utilize smaller caliber loudspeakers with lower cost compared to larger ones. In the case of same cost as using larger caliber loudspeakers, the valid vibrating membrane area of arranged smaller loudspeakers is several times than the larger loudspeakers. Thus the amplitude of vibrating membrane is much smaller under the same sound output, therefor the distortion is decreased and other advantages are brought out as well.
