The direction-variable speaker system has first and second speaker cases containing speaker units for different reproduction bands, respectively, and an intermediate case interposed between those two speaker cases. The first speaker case and the intermediate case are connected by a first pivotal shaft pivotally of each other and are given tendency to pull each other. Between the first speaker system and the intermediate case is provided a rising angle setting mechanism including a first gear cam secured to one of these cases and a stopper member secured to the other for meshing engagement with the first gear cam. The second speaker case and the intermediate case are connected by second pivotal shaft pivotally of each other and are given tendency to pull each other. Between the intermediate case and the second speaker case is provided a twisting angle setting mechanism including second gear cam secured to the second speaker case concentrically of the second pivotal shaft and third gear cam secured to the intermediate case for meshing engagement with the second gear cam.
