Abstract

The resonator component has distance pieces. The resonator walls (11) are connected to the distance piece (12) by the adhesive layer (14). The work point of the resonator component (10) depends on the free diameter of the resonator walls and the type of fixtures of the collaboratively vibrating surface. The adhesive surface is distributed over the entire inner surface of the resonator walls. Such a layer acts as an anti-resounding coating and enables the vibrations of the resonator walls to be dampened. The resonator walls on their edge areas are provided with at least one counter plate (15) as damping compound system.

Description

Die Erfindung bezieht sich auf ein Resonatorelement, bestehend aus einem Volumen mit Unterdruck, welches durch zweckmäßig gestaltete Wandungselemente nach dem Tellerfederprinzip federt und bei Druckbelastung eine sehr geringe Federkonstante aufweist, gemäß dem deutschen Patent Nr. 26 32 290 und dem österreichischen Patent Nr. 360 213. Im letzteren sind verschiedene Maßnahmen zur Dämpfung der Resonatorelemente vorgeschlagen, nämlich Gasdämpfung, Tropfendämpfung und Einspanndämpfung. Im deutschen Patent 33 47 827 ist ein Resonator mit dämpfenden äußeren Umhüllungsschichten erfunden, wovon die weiche, leichte und elastische Außenschicht am bemerkenswertesten erscheint. Bei diesen Erfindungen handelt es sich jeweils um Zusatzelemente, deren Herstellung aufwendige spezielle Technologien erfordern und hohe Kosten verursachen. In der Praxis haben sich diese Dämpfungstechniken nicht durchgesetzt.The invention relates to a resonator element consisting of a volume Vacuum, which by appropriately designed wall elements according to the Disc spring principle springs and a very low spring constant under pressure according to German Patent No. 26 32 290 and the Austrian Patent No. 360 213. In the latter are various measures to dampen the Resonator elements proposed, namely gas damping, droplet damping and Clamping damping. In German patent 33 47 827 is a resonator with damping outer covering layers invented, of which the soft, light and elastic Outer layer appears most remarkable. These inventions are each of additional elements, the manufacture of which requires complex special technologies require and cause high costs. In practice, these have Damping techniques not enforced.

Aufgabe der Erfindung ist es nun, diese Nachteile abzustellen und gleichzeitig die Herstellung zu vereinfachen. Das besondere Ziel besteht darin, den Resonator gegenüber den unvermeidlichen Fertigungstoleranzen unempfindlich zu machen und sein Dämpfungsvermögen zu erhöhen.The object of the invention is to remedy these disadvantages and at the same time Simplify manufacturing. The particular goal is the resonator make insensitive to the inevitable manufacturing tolerances and to increase its damping capacity.

Der Erfindungsgegenstand ist anhand mehrerer Ausführungsbeispiele dargestellt.The subject matter of the invention is illustrated using several exemplary embodiments.

Fig. 1 Resonatorelement mit Klebschichtdämpfung, Fig. Resonator 1 with Klebschichtdämpfung,

Fig. 2 Resonatorelement mit Klebschichtdämpfung und Konterblech, Fig. 2 resonator with Klebschichtdämpfung and counter-plate,

Fig. 3 Resonatorelement mit Klebschichtdämpfung und inneren Aussparungen. Fig. 3 resonator element with adhesive layer damping and inner recesses.

In Fig. 1 ist ein Resonatorelement 10, bestehend aus den Resonatorwandungen 11 und dem Distanzstück 12, die ein Unterdruckvolumen 13 einschließen, dargestellt. Die Resonatorwandungen 11 sind durch die Klebschicht 14 mit dem Distanzstück verbunden. Bekanntlich hängt der Arbeitspunkt des Resonatorelementes 10 in empfindlicher Weise vom freien Durchmesser der Resonatorwandungen 11 und der Art der Befestigung der mitschwingenden Fläche ab. Die Klebschicht 14 ist deshalb erfindungsgemäß über die gesamte Innenfläche der Resonatorwandungen 11 verteilt. Eine solche Schicht wirkt nach Art eines Antidröhnbelages und vermag die Schwingungen der Resonatorwandungen 11 zu dämpfen. Der zweite Vorteil ist, daß die maßgenaue Aussparung an der Klebefläche entfällt und die bisher auftretenden Probleme bei der Befestigung vermieden werden.In Fig. 1 is a resonator element 10 composed of the Resonatorwandungen 11 and the spacer 12, including a vacuum volume 13 is illustrated. The resonator walls 11 are connected to the spacer by the adhesive layer 14 . As is known, the operating point of the resonator element 10 depends in a sensitive manner on the free diameter of the resonator walls 11 and the type of fastening of the resonating surface. According to the invention, the adhesive layer 14 is therefore distributed over the entire inner surface of the resonator walls 11 . Such a layer acts like an anti-drumming coating and is able to dampen the vibrations of the resonator walls 11 . The second advantage is that the dimensionally accurate cut-out on the adhesive surface is eliminated and the problems with fastening that previously occurred are avoided.

Das Ausführungsbeispiel nach Fig. 2 ist weitgehend analog zu Fig. 1. Das Resonatorelement 20 wird auch hier von den Resonatorwandungen 11, dem Distanzstück 12, dem Unterdruckvolumen 13 gebildet und wieder durch eine vollflächige Klebe- und Dämpfungsschicht 14 verbunden. Zusätzlich wird der Randbereich der Klebeschicht 14 von einem Konterblech abgedeckt.The exemplary embodiment according to FIG. 2 is largely analogous to FIG. 1. Here, too, the resonator element 20 is formed by the resonator walls 11 , the spacer 12 , the negative pressure volume 13 and is again connected by a full-surface adhesive and damping layer 14 . In addition, the edge region of the adhesive layer 14 is covered by a counter plate.

Damit kommt die sehr viel wirkungsvollere Dämpfung durch Verbundschichten zum Tragen. (Vergleiche VDI Richtlinie 2737 "Lärmminderung durch Körperschalldämpfung").This means that the much more effective damping through composite layers comes to Carry. (Compare VDI guideline 2737 "Noise reduction through structure-borne noise reduction").

Bei dem Resonatorelement 30 nach Fig. 3, bestehend aus Resonatorwandungen 11, Distanzstück 12 und dem Unterdruckvolumen 13 ist die Klebschicht 14 in der Mitte 16 der Resonatorwandungen 11 ausgespart. Eine solche Aussparung ist unempfindlich gegen Toleranzen und verringert die mitschwingende Masse. Außerdem ist die Verformung und die Dämpfung im Randbereich größer.In the resonator element 30 according to FIG. 3, consisting of resonator walls 11 , spacer 12 and the vacuum volume 13 , the adhesive layer 14 is left out in the middle 16 of the resonator walls 11 . Such a recess is insensitive to tolerances and reduces the vibrating mass. In addition, the deformation and damping in the edge area are greater.

Diese Ausführungsbeispiele eignen sich in besonderer Weise für den Einsatz zur Schalldämpfung in Luftkanälen.These exemplary embodiments are particularly suitable for use in Soundproofing in air ducts.
