Abstract

L'invention concerne un boîtier sonore intégré à canaux multiples, de structure simple et de forme succincte qui peut obtenir un effet de son stéréo 3D sans connexion de fils compliquée se reliant aux sources sonores. Le boîtier sonore se trouve sous forme d'un rectangle long. À l'intérieur du boîtier on trouve trois canaux indépendants ou plus dans lesquels au moins un est un canal de basse extrême. L'invention remplace des boîtiers sonores d'un système existant avec un seul boîtier sonore en intégrant trois canaux indépendants ou plus dans un boîtier sonore en forme de rectangle long. Ainsi la connexion par fils entre le boîtier et la source sonore est fortement réduite. Un seul câble peut effectuer la transmission sonore de la totalité des canaux. En variante, une connexion sans fil peut également être utilisée.
