Abstract

The component is in the form of a fiber panel (1) that can be stimulated to acoustic oscillation and can output sound waves. Its fibers consist of renewable material and/or synthetic material. The fiber panel is made of high strength fibers, e.g. carbon fibers or glass fibers, which are integrated into the fiber panel in the form of a mat.

Description

Die Erfindung betrifft ein akustisches Bauteil, das zu akustischen Schwingungen anregbar und zu Abgabe von Schwallwellen geeignet ist.The invention relates to an acoustic component that causes acoustic vibrations is excitable and suitable for emitting surge waves.

Aus dem Stand der Technik ist es bekannt, aus PUR-Hartschaumplatten mit einer Plattenstärke zwischen ungefähr 5 mm und 10 mm großflächige Flachlautsprecher herzustellen. Die von einer Audioquelle, zum Beispiel einem Radioempfänger oder einer HiFi-Anlage, abgegebenen Audiosignale werden von einem Exciter umgewandelt und als Schwingungen an die Hartschaumplatte abgegeben, so daß die Hartschaumplatte mit ihrer gesamten Oberfläche als Schallquelle wirkt. Die Hartschaumplatten sind jedoch aufgrund ihrer Eigenschaften empfindlich gegen mechanische Belastungen wie Druck oder Biegung. Daher ist die Anwendung der Hartschaumplatten auf solche Einsatzfelder beschränkt, wo die genannten Bela­ stungen normalerweise nicht auftreten.It is known from the prior art to use PUR rigid foam panels with a Plate thickness between approximately 5 mm and 10 mm large flat speakers to manufacture. That from an audio source, for example a radio receiver or a hi-fi system, audio signals are emitted by an exciter converted and emitted as vibrations to the rigid foam plate, so that the hard foam panel with its entire surface acts as a sound source. The However, rigid foam panels are sensitive to their properties mechanical loads such as pressure or bending. Hence the application of the Rigid foam panels are limited to such fields of application, where the Bela usually do not occur.

Der Erfindung liegt die Aufgabe zugrunde, ein akustisches Bauteil zu schaffen, das einerseits ebenso wie Hartschaumplatten zu akustischen Schwingungen anan­ regbar und zur Abgabe von Schallwellen geeignet ist und sich andererseits durch eine hohe mechanische Belastbarkeit auszeichnet.The invention has for its object to provide an acoustic component, on the one hand, just like hard foam panels on acoustic vibrations is controllable and suitable for emitting sound waves and on the other hand through is characterized by a high mechanical resilience.

Diese Aufgabe wird erfindungsgemäß durch ein akustisches Bauteil in Form einer Faserplatte gelöst, die zu akustischen Schwingungen anregbar und zur Abgabe von Schallwellen geeignet ist, wobei die Fasern der Faserplatte aus nachwachsen­ den Rohstoffen und/oder Kunststoffen bestehen. Vorteilhafterweise kann die Fa­ serplatte durch hochfeste Fasern, wie Kohlefasern, Carbonfasern oder Glasfasern, verstärkt sein, wobei die hochfesten Fasern in Mattenform in die Faserplatte inte­ griert sein können. Vorteilhafterweise sind die hochfesten Fasern in Mattenform als Beplankung der Faserplatte angeordnet. Es besteht die Möglichkeit, die Faser­ platte mit einer Dekorschicht und/oder mit einer Metallplatte zu versehen. Je nach Vorgabe kann die Dekorschicht aus Leder, textilem Gewebe und/oder einer Kunststoffschicht gebildet sein.This object is achieved by an acoustic component in the form of a Fiberboard loosened, which can be excited to acoustic vibrations and released of sound waves is suitable, the fibers of the fiberboard growing out the raw materials and / or plastics. The company can advantageously high-strength fibers, such as carbon fibers, carbon fibers or glass fibers, be reinforced, the high-strength fibers in mat form inte in the fiberboard can be bordered. The high-strength fibers are advantageously in the form of a mat arranged as planking of the fiberboard. There is a possibility of fiber plate to be provided with a decorative layer and / or with a metal plate. Depending on The decorative layer can be made of leather, textile fabric and / or one Plastic layer can be formed.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben. Die einzige Figur zeigt einen Querschnitt durch einen akustischen Bauteil.An embodiment of the invention is shown in the drawing and will described in more detail below. The only figure shows a cross section through an acoustic component.

Die aus nachwachsenden Rohstoffen, z. B. Flachs, Jute, Kenaf, Nessel, gebildete Faserplatte 1 ist mit einer Dekorschicht 2 und einer Metallplatte 3 versehen. Für bestimmte Verwendungszwecke ist es sicher vorteilhaft, anstelle der Fasern aus nachwachsenden Rohstoffen Kunstfasern zu verwenden, wobei auch eine Kombi­ nation von Fasern aus nachwachsenden Rohstoffen und Kunstfasern denkbar ist. Die Dekorschicht 2, z. B. aus Leder, textilem Gewebe und/oder einer Kunststoff­ schicht, ist auf der Sichtseite des akustischen Bauteils angeordnet und verleiht da­ durch dem akustischen Bauteil ein gefälliges optisches Aussehen. The from renewable raw materials, e.g. B. flax, jute, kenaf, nettle, formed fiberboard 1 is provided with a decorative layer 2 and a metal plate 3 . For certain uses, it is certainly advantageous to use synthetic fibers instead of the fibers from renewable raw materials, a combination of fibers from renewable raw materials and synthetic fibers also being conceivable. The decorative layer 2 , e.g. B. made of leather, textile fabric and / or a plastic layer is arranged on the visible side of the acoustic component and gives a pleasing visual appearance through the acoustic component.

Das erfindungsgemäße akustische Bauteil kann z. B. in Kraftfahrzeugen als Funktions- oder Dekorelement in den Seitentüren, der Mittelkonsole, der Instru­ mententafel, in Rückenlehnen oder Hutablagen verwendet werden, wobei das Bauteil gleichzeitig die Funktion eines Lautsprechers übernimmt. Auf diese Weise ergeben sich ganz neue Gestaltungsmöglichkeiten von Fahrzeuginnenräumen und deren Beschallung. In ähnlicher Weise eröffnen sich neue Anwendungsfelder bei Möbeln, insbesondere für Verkleidungselemente von Fernseh- oder Phonomö­ beln. Mit dem erfindungsgemäßen Bauteilen lassen sich großflächige Lautspre­ cher in Wohnräumen integrieren, ohne daß zusätzlicher Platzbedarf entsteht.The acoustic component according to the invention can, for. B. in motor vehicles as Functional or decorative element in the side doors, the center console, the instru ment board, used in backrests or parcel shelves, the Component takes on the function of a loudspeaker at the same time. In this way there are completely new design options for vehicle interiors and their sound. Similarly, new fields of application open up Furniture, in particular for trim elements for television or phono beg. Large-area loudspeakers can be made with the components according to the invention Integrate cher in living rooms without additional space requirements.
