Title (EN) COMPACT SURROUND-SOUND EFFECTS SYSTEM
(FR) SYSTÈME À EFFETS DE SON D'AMBIANCE COMPACT
Abstract:
(EN) A loudspeaker suitable for the generation of surround-sound effects comprising a plurality of transducers that are together arranged to generate one or more beams of sound, at least one of which beams is steerable, wherein the transducers are arranged to reproduce sound only at frequencies higher than a selected lower frequency limit of 250 Hz or more. The loudspeaker may be foldable or dismantable so as to allow greater portability and may have means for interacting with an external electronics device, for example to allow low frequency sound signals to be reproduced by woofers in the external device.
(FR) La présente invention concerne un haut-parleur conçu pour produire des effets de son d'ambiance qui comprend une pluralité de transducteurs combinés pour générer un ou plusieurs rayons acoustiques dont l'un au moins est orientable, lesdits transducteurs étant configurés pour reproduire le son uniquement dans des fréquences supérieures à un seuil de fréquence égal ou supérieur à 250 Hz. Le haut-parleur peut être repliable ou démontable pour offrir une meilleure portabilité et peut comporter des moyens dédiés à l'interaction avec un dispositif électronique externe, par exemple pour permettre la reproduction de signaux sonores basse fréquence par des haut-parleurs de graves du dispositif externe.
