Title
(EN) SYSTEM AND METHOD FOR DIRECTIONALLY RADIATING SOUND
(FR) SYSTÈME ET PROCÉDÉ DE DIFFUSION DIRECTIONNELLE DU SON
Abstract
(EN)
An audio system for a vehicle having a plurality of seat positions includes a plurality of sources of audio signals. Respective directional loudspeaker arrays are mounted at the seat positions. Any of the sources are selectable to any of the seat positions through control circuitry in response to an input from an occupant of the vehicle. Processing circuitry is coupled to the control circuitry and is between the plurality of sources in each respective directional loudspeaker array.
(FR)
L'invention concerne un système audio pour un véhicule présentant une pluralité de positions du siège, comprenant une pluralité de sources de signaux audio. Les réseaux de haut-parleurs directionnels correspondants sont montés sur les positions du siège. Des sources peuvent être sélectionnées pour chaque position du siège par le circuit de commande, lorsqu'un occupant s'installe dans le véhicule. Le circuit de traitement est couplé au circuit de commande et il est placé entre la pluralité de sources dans chaque réseau de haut-parleurs directionnels correspondant.
