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.
Claims12
Conical loudspeaker, including a magnet system (10) having a tubular moving coil carrier 914) with a lower end that is provided with a moving coil (15), which projects into an air gap (16) of the magnet (10), and with an upper end that is connected to an end of a conical membrane (12), which has the smaller of the two diameters, characterized in that
- a substantially conical stabilizing element (19) is arranged between an underside (20) of the conical membrane (12) and the magnet (10), having its upper end with a greater diameter joined to an underside (20) of the membrane (12), and having its lower end joined to point intermediate said upper and lower end of an outside surface (17) of the moving coil carrier (14).
