Abstract
In order to stabilize conical loudspeakers, it is recommended according to the present invention that the underside (20) of the membrane (12) be joined by means of a stabilizing element (19) joined to the moving coil carrier (14). This triangular structure alone results in sufficient stabilization of the membrane. If, in addition, the underside (20) of the membrane (12) is supported by the stabilizing element (19) at a point at which the first radial oscillation mode occurs, premature decoupling of the outer regions of the membrane is prevented.
