The invention essentially consists in that cross-sectional corners and angular folds are eliminated when the housing is formed, and a rounded or round shape is provided, and in that hard PVC plastic or plastic with the characteristics of hard PVC is used to form the loudspeaker housing or the internal surfaces of the housing. It is advantageous herein if the sound conducting surfaces of the housing or the folded pressure flow path of the same is formed by a strip, guided in loops, with folded sections through a partial wall projecting from the internal circumference into a loop pocket and this loop routing is disposed between two side walls. <IMAGE>
