Title
(EN) SPEAKER APPARATUS, METHOD FOR PROCESSING INPUT SIGNALS THEREOF, AND AUDIO SYSTEM
(FR) APPAREIL DE HAUT-PARLEUR, SON PROCÉDÉ DE TRAITEMENT DE SIGNAUX D'ENTRÉE, ET SYSTÈME AUDIO
Abstract
(EN)
A speaker apparatus, a method for processing input signals of the speaker apparatus and an audio system are provided. The speaker apparatus includes: a first plurality of speakers, arranged at an interval in a row, where acoustic energy radiation generated by the first plurality of speakers is greater in a first zone than in a second zone in a first frequency range; a second plurality of speakers, symmetrically disposed at two sides of the first plurality of speakers with openings at the two sides facing outwardly, where acoustic energy radiation generated by the second plurality of speakers is greater in a third zone than in a fourth zone in a second frequency range; and the first frequency range overlaps with the second frequency range. Therefore, the speaker apparatus, the method and the audio system can achieve a wide spacious effect and provide a near-real surround experience to listeners.
(FR)
L'invention concerne un appareil de haut-parleur, un procédé de traitement de signaux d'entrée de l'appareil de haut-parleur et un système audio. L'appareil de haut-parleur comprend : une première pluralité de haut-parleurs, agencés à un intervalle dans une rangée, le rayonnement d'énergie acoustique généré par la première pluralité de haut-parleurs étant supérieur dans une première zone à celui dans une seconde zone dans une première plage de fréquences ; une seconde pluralité de haut-parleurs, disposés symétriquement au niveau de deux côtés de la première pluralité de haut-parleurs avec des ouvertures au niveau des deux côtés tournés vers l'extérieur, un rayonnement d'énergie acoustique généré par la seconde pluralité de haut-parleurs étant supérieur dans une troisième zone à celui dans une quatrième zone dans une seconde plage de fréquences ; et la première plage de fréquences chevauche la seconde plage de fréquences. Par conséquent, l'appareil de haut-parleur, le procédé et le système audio peuvent obtenir un effet spacieux large et fournir une expérience ambiophonique presque réelle à des auditeurs.
