Claims (6)

Patentansprüche:Patent claims: 1. Membran, insbesondere gewellte Membran für elektrodynamische Großlautsprecher, an der die von den Sprechströmen durchflossenen Leiter befestigt sind, dadurch gekennzeichnet, daß die Einzelleiter unabhängig voneinander in eine Isoliermasse eingebettet sind, mit der sie unmittelbar an der Membran befestigt sind.1. Diaphragm, especially corrugated diaphragm for large electrodynamic loudspeakers, to which the conductors through which the speech currents flow are attached, characterized in that the individual conductors are independent are embedded from each other in an insulating compound, with which they are directly connected to the Membrane are attached. 2. Membran nach Anspruch 1, dadurch gekennzeichnet, daß die stromführenden Leiter in Leisten aus Isoliermaterial eingebettet sind.2. Membrane according to claim 1, characterized in that the current-carrying Heads are embedded in strips of insulating material. 3. Membran nach Anspruch 2, dadurch gekennzeichnet, daß sich die Isolierleisten auf ihrer ganzen Länge der Membranoberfläche eng anschmiegen.3. Membrane according to claim 2, characterized in that the insulating strips cling tightly to the surface of the membrane over its entire length. 4. Membran nach Anspruch 2 und 3, dadurch gekennzeichnet, daß auf der einen Seite der Membran die Isolierleisten mit den stromführenden Leitern, auf der anderen Seite Scheiben aus Isoliermaterial angeordnet sind, die durch die Membran hindurch mit den Leisten verbunden sind.4. Membrane according to claim 2 and 3, characterized in that on the one hand On the side of the membrane, the insulating strips with the current-carrying conductors, on the other Side discs of insulating material are arranged, which pass through the membrane connected to the ledges. 5. Membran nach Anspruch 1 bis 4, dadurch gekennzeichnet, daß die mittels Isoliermaterial an der Membran befestigten Leiter noch durch weitere Befestigungsmittel (ζ. B. durch Nieten) mit der Membran verbunden sind.5. Membrane according to claim 1 to 4, characterized in that the means of insulating material Conductors attached to the membrane are also connected to the membrane by further fastening means (e.g. rivets) are. 6. Membran nach Anspruch 1 bis 5, dadurch gekennzeichnet, daß die Leiter in ein anfänglich plastisches, durch besondere (z.B. thermische) Behandlung erhärtendes Isoliermaterial (wie Hartgummi) eingebettet sind.6. Membrane according to claim 1 to 5, characterized in that the conductors in a Initially plastic insulating material that hardens through special (e.g. thermal) treatment (like hard rubber) are embedded.
