Abstract
(DE)
Planarlautsprecher, umfassend ein flächiges Klangpanel, eine Halterung, wenigstens eine, vorzugsweise an der Halterung befestigte, Antriebseinheit zum Antreiben des Klangpanels, und zumindest eine, die Antriebseinheit nicht umgebende Stabilisierungsvorrichtung zum Stabilisieren einer Bewegung des Klangpanels, wobei die Stabilisierungsvorrichtung zwischen dem Klangpanel und der Halterung angeordnet ist und zumindest einen Hubabschnitt aufweist, welcher beweglich, flexibel und/oder elastisch ausgebildet ist, und zumindest eine, die Antriebseinheit nicht umgebende Zentriervorrichtung zum Zentrieren des Klangpanels und/oder wenigstens eines Teils der Antriebseinheit, wobei die Zentriervorrichtung in einer anderen Ebene als die Stabilisierungsvorrichtung angeordnet ist und zumindest einen Hubabschnitt aufweist, welcher beweglich, flexibel und/oder elastisch ausgebildet ist.
(EN)
The invention relates to a planar loudspeaker, comprising a flat tone panel, a holder, at least one drive unit, preferably fixed to the holder, for driving the tone panel, and at least one stabilization apparatus, not enclosing the drive unit, for stabilizing a movement of the tone panel, wherein the stabilization apparatus is arranged between the tone panel and the holder and has at least one travel section, which is designed to be movable, flexible and/or elastic, and at least one centering apparatus, not enclosing the drive unit, for centering the one panel and/or at least one part of the drive unit, wherein the centering apparatus is arranged in a different plane than the stabilization apparatus and has at least one travel section, which is designed to be movable, flexible and/or elastic.
(FR)
L’invention concerne un haut-parleur plan comprenant un panneau acoustique plan, un support, au moins une unité d'entraînement, de préférence fixée au support, pour l'entraînement du panneau acoustique, et au moins un dispositif de stabilisation n’entourant pas l’unité d'entraînement, destiné à stabiliser un mouvement du panneau acoustique, le dispositif de stabilisation étant disposé entre le panneau acoustique et le support et présentant au moins une partie de levage qui est mobile, flexible et/ou élastique, et au moins un dispositif de centrage n'entourant pas l'unité d'entraînement, destiné à centrer le panneau acoustique et/ou au moins une partie de l'unité d'entraînement, le dispositif de centrage étant disposé dans un autre plan que le dispositif de stabilisation et présentant au moins une partie de levage qui est mobile, flexible et/ou élastique.
