Abstract

La présente invention concerne un appareil à haut-parleurs combinés et un procédé de reproduction d'effet sonore. L'appareil à haut-parleurs combinés comprend des haut-parleurs ayant au moins deux bandes de fréquence et présente au moins deux zones de production sonore. Chacune des zones de production sonore est agencée en anneau concentrique de l'intérieur vers l'extérieur de l'appareil à haut-parleurs combinés. Le haut-parleur de chaque bande de fréquence est disposé dans chaque zone de production sonore de manière prédéfinie, et est conçu pour générer un son en réponse à une entrée de signaux audio dans la bande de fréquence correspondante, de sorte que chaque zone de production sonore génère un effet sonore de bande de fréquence correspondante. Par conséquent, les effets constitués par l'effet sonore généré dans chaque zone de production sonore se chevauchent entre eux au cours du processus de propagation de l'appareil à haut-parleurs combinés à l'oreille humaine, de sorte que l'effet sonore de toutes les bandes de fréquences sonores de l'appareil à haut-parleurs combinés puisse être formé et que le son d'origine soit reproduit. Les haute, moyenne et basse fréquences sont distinguées automatiquement par l'oreille humaine et pas par l'équipement, de sorte à améliorer considérablement l'expérience auditive des utilisateurs.
