Claims (9)

1. Abgasführendes Rohr (1) oder dergleichen Bauteil für Brennkraftmaschinen, insbesondere für Kfz, dadurch gekennzeichnet, daß in einen Wandungsschnitt des Rohres (1) oder Bauteiles eine Membran (2) aus temperatur- und druckstabilem Werkstoff dicht eingefügt ist, und daß an die Membran (2) ein Schwingungserzeuger (3) angeschlossen oder angekoppelt ist, mittels dessen die Membran (2) zur Schwingung und Erzeugung von Schallwellen anregbar ist.1. exhaust pipe ( 1 ) or the like component for internal combustion engines, especially for motor vehicles, characterized in that in a wall section of the tube ( 1 ) or component, a membrane ( 2 ) made of temperature and pressure-stable material is inserted tightly, and that to the Membrane ( 2 ) a vibration generator ( 3 ) is connected or coupled, by means of which the membrane ( 2 ) can be excited to vibrate and generate sound waves. 2. Rohr oder Bauteil nach Anspruch 1, dadurch gekennzeichnet, daß die Membran (2) aus Metall besteht.2. Pipe or component according to claim 1, characterized in that the membrane ( 2 ) consists of metal. 3. Rohr oder Bauteil nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Membran (2) aus dünnem Stahlblech besteht.3. Pipe or component according to claim 1 or 2, characterized in that the membrane ( 2 ) consists of thin sheet steel. 4. Rohr oder Bauteil nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß die Wandung des Rohres (1) oder Bauteiles im Bereich des Wandungsausschnittes flach und eben ausgebildet ist und die Membran (2) als ebenes Flächenelement in den Wandungsausschnitt eingepaßt ist.4. Pipe or component according to one of claims 1 to 3, characterized in that the wall of the tube ( 1 ) or component in the region of the wall cutout is flat and flat and the membrane ( 2 ) is fitted as a flat surface element in the wall cutout. 5. Rohr oder Bauteil nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die Membran (2) mit ihrer Randkante umlaufend stoffschlüssig mit dem Rand des Rohres (1) oder Bauteiles stoffschlüssig verbunden ist, der den Wandungsausschnitt umgibt.5. Pipe or component according to one of claims 1 to 4, characterized in that the membrane ( 2 ) with its peripheral edge is integrally connected to the edge of the tube ( 1 ) or component which surrounds the wall section. 6. Rohr oder Bauteil nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß die Membran (2) als verdünnte Wandung des Rohres (1) oder Bauteiles ausgebildet ist.6. Pipe or component according to one of claims 1 to 5, characterized in that the membrane ( 2 ) is designed as a thinned wall of the tube ( 1 ) or component. 7. Rohr oder Bauteil nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, daß an die Membran (2), vorzugsweise mittig ihrer Fläche, als Schwingungserzeuger (3) ein elektrischer, elektromagnetischer oder hydraulischer Impulsgeber angeschlossen ist.7. Pipe or component according to one of claims 1 to 6, characterized in that an electrical, electromagnetic or hydraulic pulse generator is connected to the membrane ( 2 ), preferably in the center of its surface, as a vibration generator ( 3 ). 8. Rohr oder Bauteil nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß der Schwingungserzeuger (3) an für die Schwingung des Abgases bestimmende Teile der Brennkraftmaschine gekoppelt ist.8. Pipe or component according to one of claims 1 to 7, characterized in that the vibration generator ( 3 ) is coupled to parts of the internal combustion engine which determine the vibration of the exhaust gas. 9. Rohr oder Bauteil nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß der Schwingungserzeuger (3) unabhängig von der Brennkraftmaschine einstellbar ist.9. Pipe or component according to one of claims 1 to 7, characterized in that the vibration generator ( 3 ) is adjustable independently of the internal combustion engine.
