Title (EN) MULTIPLE DISPERSION STANDALONE STEREO LOUDSPEAKERS
(FR) HAUT-PARLEURS STÉRÉO AUTONOMES À DISPERSION MULTIPLE
Abstract:
(EN) Embodiments are directed to a speaker system that contains an array of multiple dispersion drivers that creates an expansive acoustic pattern to playback multi-channel audio content through a standalone speaker. The speaker system comprises an interface receiving stereo audio; an upmixer generating surround sound formatted audio from the stereo audio including one or more height channels; a virtualizer/downmixer component coupled to the upmixer and generating speaker feeds for two or more loudspeaker output sections, configured to play back the stereo audio, wherein each output section is further configured to play its own dedicated stereo audio signals; and a set of drivers each coupled to a respective output section and configured to project sound in at least two different dispersion patterns.
(FR) Des modes de réalisation concernent un système de haut-parleur qui contient un réseau de multiples pilotes de dispersion qui crée un motif acoustique expansif permettant de lire un contenu audio multicanal par l'intermédiaire d'un haut-parleur autonome. Le système de haut-parleur comprend : une interface recevant un audio stéréo; un mélangeur élévateur générant un audio formaté de son ambiophonique à partir de l'audio stéréo comprenant un ou plusieurs canaux en hauteur; un composant virtualiseur/mélangeur abaisseur couplé au mélangeur élévateur et générant des alimentations de haut-parleur pour deux sections de sortie de haut-parleur ou plus, configuré pour lire l'audio stéréo, chaque section de sortie étant en outre configurée pour lire ses propres signaux audio stéréo dédiés; et un ensemble de pilotes couplés chacun à une section de sortie respective et configurés pour projeter un son dans au moins deux motifs de dispersion différents.
