Title
(EN) ACOUSTIC OUTPUT DEVICE AND CONTROL METHOD FOR ACOUSTIC OUTPUT DEVICE
(FR) DISPOSITIF DE SORTIE ACOUSTIQUE ET PROCÉDÉ DE COMMANDE POUR DISPOSITIF DE SORTIE ACOUSTIQUE
(JA) 音響出力装置および音響出力装置の制御方法
Abstract
(EN) The acoustic output device according to the present disclosure comprises: a housing (520), at least one outwardly-directed microphone (100) provided in the housing so as to be directed toward the outside of the housing, and at least two drivers (140(1)-(L)) which are provided inside the housing and which respectively generate acoustic control sounds on the basis of acoustic control signals. In addition, in the control method for the acoustic output device according to the present disclosure, a processor (300a) causes the at least two drivers, provided inside the housing in which the at least one microphone is provided so as to be directed toward the outside thereof, to generate acoustic control sounds on the basis of acoustic control signals.
(FR) Le dispositif de sortie acoustique selon la présente invention comprend : un boîtier (520), au moins un microphone dirigé vers l'extérieur (100) disposé dans le boîtier de façon à être dirigé vers l'extérieur du boîtier, et au moins deux moteurs de haut-parleur (140(1)-(L)) qui sont disposés à l'intérieur du boîtier et qui génèrent respectivement des sons de commande acoustique sur la base de signaux de commande acoustique. De plus, dans le procédé de commande du dispositif de sortie acoustique selon la présente invention, un processeur (300a) amène lesdits au moins deux moteurs de haut-parleur, disposés à l'intérieur du boîtier dans lequel le ou les microphones sont disposés de façon à être dirigés vers l'extérieur de celui-ci, à générer des sons de commande acoustique sur la base de signaux de commande acoustique.
(JA) 本開示に係る音響出力装置は、筐体(520)と、筐体に、筐体の外部に向けて設けられる1以上の外向きマイクロホン(100)と、筐体の内部に設けられる、それぞれ音響制御信号に基づく音響制御音を発生させる2以上のドライバ(140(1)-(L))と、を備える。また、本開示に係る音響出力装置の制御方法は、プロセッサ(300a)が、1以上のマイクロホンが外部に向けて設けられる筐体の内部に設けられる2以上のドライバに、それぞれ音響制御信号に基づく音響制御音を発生させる。
