Definitions
- the invention relates to a membrane for electroacoustic transducers, in particular loudspeakers and headphones.
- the shape of this membrane is composed of at least two cones of different opening angles, the cones also being able to close in a dome-like manner. It is essential for the invention that only very specific opening angles are used, namely the angles 163, 157, 140, 114, 98, 82 and 66 degrees.
- the novelty of the present patent application is that the membrane geometry produces an irregularly structured amplitude behavior and decay behavior (decay spectrum) which is similar to the material-related properties of the human hearing apparatus. If the decay spectrum of the membrane matches the decay spectrum of the ear, the reverberation of parts of the membrane (partial vibrations) is no longer perceived as discoloration and a natural sound impression is created. Through years of research, I was able to empirically determine the cone angles that correspond to this desired behavior.

Abstract
Description
Die Erfindung bezieht sich auf eine Membran für elektroakustische Wandler, insbesondere Lautsprecher und Kopfhörer. Die Form dieser Membran setzt sich aus mindestens zwei Konen unterschiedlichen Öffnungswinkels zusammen, wobei sich die Konen auch kalottenartig schließen können. Wesentlich für die Erfindung ist, daß nur ganz bestimmte Öffnungswinkel verwendet werden, und zwar die Winkel 163,157,140,114,98, 82 und 66 grad.The invention relates to a membrane for electroacoustic transducers, in particular loudspeakers and headphones. The shape of this membrane is composed of at least two cones of different opening angles, the cones also being able to close in a dome-like manner. It is essential for the invention that only very specific opening angles are used, namely the angles 163, 157, 140, 114, 98, 82 and 66 degrees.
Es sind bereits Membranformen bekannt, die oberflächlich gesehen ähnlich ausschauen und sich aus mehreren Konen zusammensetzen (Deutschland Pat. 899048, Frankreich Pat. 1251,411, GB 369.992). Diese Patente beziehen sich jedoch nicht auf bestimmte Winkel und verfolgen außerdem eine gänzlich andere Zielsetzung.. Diese Zielsetzung ist eine gleichmäßige Wiedergabe aller Tonfrequenzen, wobei aus meßtechnischer Sicht schon gute Erfolge erzielt wurden.Membrane shapes are already known which, on the surface, look similar and are composed of several cones (Germany Pat. 899048, France Pat. 1251.411, GB 369.992). However, these patents do not relate to specific angles and also pursue a completely different objective. This objective is an even reproduction of all sound frequencies, and good results have already been achieved from a measurement point of view.
Das Neue der vorliegenden Patentanmeldung ist, daß durch die Membrangeometrie ein unregelmäßig strukturiertes Amplitudenverhalten und Ausschwingverhalten (Zerfallsspektrum) erzeugt wird, welches den materialbedingten Eigenschaften des menschlichen Hörapparates ähnlich ist. Stimmt das Zerfallsspektrum der Membran mit dem Zerfallsspektrum des Ohres überein, so wird das Nachschwingen von Teilen der Membran (Partialschwingungen) nicht mehr als Verfärbung wahrgenommen und es entsteht ein natürlicher Klangeindruck. Durch jahrelange Forschungen konnte ich empirisch jene Konuswinkel bestimmen, die diesem erwünschten Verhalten entsprechen.The novelty of the present patent application is that the membrane geometry produces an irregularly structured amplitude behavior and decay behavior (decay spectrum) which is similar to the material-related properties of the human hearing apparatus. If the decay spectrum of the membrane matches the decay spectrum of the ear, the reverberation of parts of the membrane (partial vibrations) is no longer perceived as discoloration and a natural sound impression is created. Through years of research, I was able to empirically determine the cone angles that correspond to this desired behavior.
Eine ausführlichere Erklärung der grundlgend neuen Theorie der Klangwahrnehmung bringt das beiliegende Buch "Das Maß des Klanges" vom Patentanmelder (ISBN 3-907073-32-0).A more detailed explanation of the fundamentally new theory of sound perception is provided in the accompanying book "The measure of sound" by the patent applicant (ISBN 3-907073-32-0).
