Wide frequency range sound generation system for internal noise reduction measure in motor vehicle, has vibratable diaphragm made of several passive tightened layers and active function elements

Abstract: A vibratable diaphragm (1) having passive tightened single layers of isotropic or anisotropic layers with active function elements (4) formed as a multilayer bond, is held in a holder (2). The diaphragm accepts deformation energy for different stable equilibrium positions, the change in which causes sound.

Function multistable hybrid compound as force and displacement converter, has functional material that can be driven inserted into multilayer compound for introducing deformation energy

Abstract: The arrangement consists of isotropic and anisotropic materials with several passively braced individual layers arranged asymmetrically with respect to each other that adopt multistable deformation conditions in various stable equilibrium states when deformation energy is introduced. For introduction of deformation energy, at least one layer of a functional material that can be driven is inserted into a multilayer compound, which is changed to a different equilibrium state by driving the layer(s) and the introduction of energy is finished with the change.

Multi Function Stable hybrid composite (FMH) as fuel and displacement transducer

Abstract: Function multistable hybrid multilayer composite for producing adjusting movements, with at least a biased passive layer and at least one layer of an activatable functional material through which the multi-layer composite can be transferred from one to another position of equilibrium, characterized in that the multilayer composite more passive, tensioned against one another individual layers with having such framed unbalanced layer removal from anisotropic materials, the multilayer composite may take various deformation states in different positions of stable equilibrium.

Funktionsmultistabiler Hybridverbund (FMH) als Kraft- und Wegübersetzer Multi Function Stable hybrid composite (FMH) as power and displacement transducer

Abstract: Funktionsmultistabiler hybrider Mehrschichtverbund zur Erzeugung von Stellbewegungen, mit mindestens einer vorgespannten passiven Schicht und mindestens einer Schicht aus einem ansteuerbaren Funktionsmaterial, durch die der Mehrschichtverbund von einer in eine andere Gleichgewichtslage uberfuhrt werden kann, dadurch gekennzeichnet, dass der Mehrschichtverbund mehrere passive, gegeneinander verspannte Einzellagen mit derart gestaltetem unsymmetrischem Schichtausbau aus anisotropen Werkstoffen aufweist, dass der Mehrschichtverbund verschiedene Verformungszustande in unterschiedlichen stabilen Gleichgewichtslagen einnehmen kann. Function Multi Stable hybrid multilayer composite for producing adjusting movements, with at least one pre-loaded passive layer and at least one layer of a controllable functional material through which the multi-layer composite can be transferred from one to another equilibrium, characterized in that the multilayer composite more passive, tensioned against one another individual layers with so framed unbalanced expansion layer of anisotropic materials, in that the multilayer composite can assume different deformation states in different stable equilibrium.
