Abstract

Parametrische Lautsprecher, basierend auf einem modulierten Ultraschallträgersignal, erzeugen eine starke Richtwirkung. Diese starke Richtwirkung macht eine direkte Übertragungsstrecke vom Lautsprecher zum Zuhörer erforderlich. Hindernisse in dieser Strecke wirken als Reflektor oder Absorber. Die vorliegende Erfindung beschreibt eine mechanische Anordnung eines parametrischen Lautsprechers mit einem beweglichen Reflektor (11). Die Anordnung ermöglicht, den ausgesandten Schall sich bewegenden Zuhörern nachzuführen. Es ergeben sich vorteilhafte Einbaumöglichkeiten, z.B. im Dachhimmel von Fahrzeugen oder als mobiles System.
