Description
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen eines akustischen Widerstandes sowie einen akustischen Widerstand. The present invention relates to a method for producing an acoustic resistance and an acoustic resistance.
Es ist eine Aufgabe der vorliegenden Erfindung, ein Verfahren zum Herstellen von akustischen Widerständen vorzusehen, welches eine verbesserte und flexiblere Herstellung von akustischen Widerständen ermöglicht. It is an object of the present invention to provide a method for producing acoustic resistances, which enables an improved and more flexible production of acoustic resistances.
Diese Aufgabe wird durch ein Verfahren zum Herstellen von akustischen Widerständen nach Anspruch 1 sowie durch einen akustischen Widerstand nach Anspruch 5 gelöst. This object is achieved by a method for producing acoustic resistors according to claim 1 and by an acoustic resistor according to claim 5.
Somit wird ein Verfahren zum Herstellen eines akustischen Widerstandes vorgesehen. Eine Mehrzahl von ersten Löchern wird in einem Basismaterial mit einer ersten und zweiten Ausdehnung erzeugt, um ein Lochmuster zu erzeugen. Eine Lochgröße und/oder ein Lochabstand ist entlang der ersten und/oder zweiten Ausdehnung ungleichmäßig verteilt ausgestaltet. Thus, a method for producing an acoustic resistance is provided. A plurality of first holes are formed in a base material having first and second dimensions to produce a hole pattern. A hole size and / or a hole spacing is configured unevenly distributed along the first and / or second extension.
Die ersten Löcher können beispielsweise gestanzt, gelasert, per Ionenbeschuss oder per Wasserstrahlschneiden erzeugt oder geätzt werden. For example, the first holes may be punched, lasered, ion bombarded, or water jet cut or etched.
Die Erfindung betrifft den Gedanken, einen akustischen Widerstand beispielsweise durch ein Stanzen eines Basismaterials herzustellen, d.h. in dem Basismaterial wird ein Lochmuster eingestanzt. Durch Variation der Lochgröße sowie des Lochabstandes zwischen benachbarten gestanzten Löchern kann die akustische Dämpfung eines akustischen Widerstandes entlang der Achsen des akustischen Widerstandes variiert werden. Damit kann ein akustischer Widerstand vorgesehen werden, welcher einen unterschiedlichen Dämpfungswert in unterschiedliche Koordinaten aufweist. Die Dämpfung könnte in eine Richtung kontinuierlich zunehmen bzw. sie kann linear ausgestaltet sein. The invention relates to the idea of producing an acoustic resistance, for example by punching a base material, i. a hole pattern is punched in the base material. By varying the hole size and the hole spacing between adjacent punched holes, the acoustic damping of an acoustic resistance along the axes of the acoustic resistance can be varied. Thus, an acoustic resistance can be provided which has a different attenuation value in different coordinates. The attenuation could increase continuously in one direction or it can be made linear.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Further embodiments of the invention are the subject of the dependent claims.
Vorteile und Ausführungsbeispiele der Erfindung werden nachstehend unter Bezugnahme auf die Zeichnungen näher erläutert. Advantages and embodiments of the invention are explained below with reference to the drawings.
Optional kann der Durchmesser des Loches
Gemäß der Erfindung wird durch das oben beschriebene Verfahren ein Lochmuster in das Basismaterial
Gemäß der Erfindung lässt sich somit ein akustischer Widerstand erreichen, der einen Dämpfungsgradienten in eine bestimmte Richtung aufweisen kann. Die Dämpfung kann beispielsweise kontinuierlich zunehmen oder abnehmen. Die Funktion der Zunahme über eine Koordinate des Basismaterials ist frei einstellbar. Sie kann, muss aber nicht linear zunehmen bzw. abnehmen. Gemäß der Erfindung ist eine Zunahme des Widerstandes mit einer anschließenden Abnahme entlang einer Koordinate oder mehrerer Koordinaten möglich. Dies kann beispielsweise erreicht werden, indem die Größe der Löcher und der Abstand der gestanzten Löcher zueinander variieren. Bei einer Variation des Abstandes muss das verwendete Werkzeug (Stempel, Buchse) nicht gewechselt werden. According to the invention, an acoustic resistance can thus be achieved which can have a damping gradient in a certain direction. The damping can, for example, continuously increase or decrease. The function of the increase over a coordinate of the base material is freely adjustable. It can, but does not have to increase or decrease linearly. According to the invention, an increase of the resistance with a subsequent decrease along a coordinate or more coordinates possible. This can be achieved, for example, by varying the size of the holes and the distance between the punched holes. With a variation of the distance, the tool used (punch, bush) must not be changed.
Gemäß der Erfindung kann eine Variation der Dämpfung nicht nur entlang einer linearen Koordinatenrichtung, sondern kann auch anderweitig erfolgen. Beispielsweise bei runden Folien kann die Dämpfung in radialer Richtung abnehmen bzw. zunehmen. Die Änderung des akustischen Widerstandes kann kontinuierlich oder stufig bzw. sprungartig verlaufen. According to the invention, a variation of the attenuation not only along a linear coordinate direction, but can be done otherwise. For example, in the case of round films, the damping in the radial direction may decrease or increase. The change in the acoustic resistance can be continuous or stepped or jumped.
Gemäß der Erfindung können die Löcher als runde Löcher, eckige Löcher oder dergleichen ausgestaltet sein. According to the invention, the holes may be configured as round holes, angular holes or the like.
