Abstract

The combination has a magnetic system and a driver comprising two equivalent bar magnets (5, 6) and two pole plates (7, 8). The pole plates are bent in a plane and are in a same direction, and a wavelike membrane (9) is provided in an air space. The membrane is provided with a meander shape strip conductor, and has a front/mounting plate. The magnets are made from painted neodymium iron, neodymium iron boron, rare earth cobalt and samarium cobalt.

Description

Bei der Erfindung handelt es sich um eine Fortentwicklung des von Oskar Heil entwickelten „Heil Air Motion Transformers" (US – Patent 3.832.499 von 1977) unter Einbeziehung des Gebrauchsmusters von Norman Gerkinsmeyer (Aktenzeichen 202 07 154.5 Deutsches Patent- und Markenamt).at The invention is an evolution of the Oskar Healing developed "salvation Air Motion Transformers "(US Patent 3,832,499 from 1977) incorporating the utility model of Norman Gerkinsmeyer (Reference 202 07 154.5 German Patent and Trademark Office).

Bisherige -flache- Konstruktionen weisen die Eigenschaft auf, zu höheren Frequenzen hin den Schall zu bündeln. Dieses Verhalten ist allen Flächenstrahlern mit ebenen Membranen gemeinsam. Der Bündelungseffekt tritt in Abhängigkeit von der Membranbreite ab einer bestimmten Frequenz auf.Previous flat structures have the property of becoming higher frequencies to bundle the sound. This behavior is all surface radiators common with flat membranes. The bundling effect is dependent of the membrane width from a certain frequency on.

In vielen Fällen ist dieser Bündelungseffekt unerwünscht. Das erfindungsgemäße Magnetsystem behebt diesen Mangel dadurch, das es auch für hohe Frequenzen kreisförmige Wellenfronten erzeugt. Je, nach gewählter Ausführung lässt sich der Öffnungswinkel der Schallwelle dem Bedarfsfall anpassen.In many cases this bundling effect is undesirable. The Magnetic system according to the invention fixes this lack thereby, that it also for high frequencies circular wavefronts generated. Je, after chosen execution let yourself the opening angle adjust the sound wave to the case of need.

Das erfindungsgemäße Magnetsystem und Treiber ist für folgende Einsatzgebiete gedacht: Der Hifi- und High-End-Bereich, Car Hifi-Bereich und der professionlelle Beschallungsbereich.The Magnetic system according to the invention and driver is for the following areas of application: the hi-fi and high-end sector, Car hi-fi area and the professional sound system.

2: Der erfindungsgemäße Treiber erzeugt für alle Frequenzen den Abschnitt einer kreisförmigen Welle. Der Öffnungswinkel ist abhängig vom durch den Treiber gebildeten Kreisbogen. 2 The driver according to the invention generates the section of a circular wave for all frequencies. The opening angle depends on the arc formed by the driver.
