(EN) ACOUSTIC OUTPUT DEVICE
(FR) DISPOSITIF DE SORTIE ACOUSTIQUE
(ZH) 一种声学输出装置
Abstract
(EN) The present application relates to an acoustic output device. The acoustic output device comprises: at least one low-frequency acoustic driver, the at least one low-frequency acoustic driver outputting sound from at least two first sound guide holes; at least one high-frequency acoustic driver, the at least one high-frequency acoustic driver outputting sound from at least two second sound guide holes; and a controller, configured to enable the low-frequency acoustic driver to output sound within a first frequency range, and enable the high-frequency acoustic driver to output sound within a second frequency range, wherein the second frequency range comprises a frequency higher than the first frequency range.
(FR) L'invention a trait à un dispositif de sortie acoustique. Le dispositif de sortie acoustique comprend : au moins un circuit d'attaque acoustique basse fréquence, le ou les circuits d'attaque acoustiques basse fréquence émettant un son à partir d'au moins deux premiers trous de guidage de son ; au moins un circuit d'attaque acoustique haute fréquence, le ou les circuits d'attaque acoustiques haute fréquence émettant un son à partir d'au moins deux seconds trous de guidage de son ; et un dispositif de commande, conçu pour permettre au circuit d'attaque acoustique basse fréquence d'émettre un son dans une première plage de fréquences, et permettre au circuit d'attaque acoustique haute fréquence d'émettre un son dans une seconde plage de fréquences, la seconde plage de fréquences comprenant une fréquence supérieure à la première plage de fréquences.
(ZH) 本申请涉及一种声学输出装置。所述声学输出装置包括:至少一个低频声学驱动器,所述至少一个低频声学驱动器从至少两个第一导声孔输出声音;至少一个高频声学驱动器,所述至少一个高频声学驱动器从至少两个第二导声孔输出声音;以及控制器,被配置为使所述低频声学驱动器输出在第一频率范围内的声音,并且使所述高频声学驱动器输出在第二频率范围内的声音,其中,所述第二频率范围中包括高于所述第一频率范围的频率。
