Abstract
(EN)
An electric device system according to the present invention comprises an electric device that transmits indoor state information including information about presence or absence of a person in a room and about a direction of the person relative to the electric device and a sound output apparatus comprising: a plurality of microphones that collect peripheral sounds; a speaker that outputs sounds; a receiving means that receives the indoor state information from the electric device; and a controller that determines a direction of a sound source relative to a reference position by use of information of the sounds collected by the plurality of microphones. The controller comprises: a determination means that determines the direction of the person relative to the reference position by combining the information of the direction of the source obtained by using the information of the sounds collected by the plurality of microphones with the indoor state information acquired from the electric device; and a sound output control means that controls the output of sound of the speaker by use of the information of the direction of the person determined by the determination means.

Un système de dispositif électrique selon la présente invention comprend un dispositif électrique qui transmet des informations d'état d'intérieur comprenant des informations sur la présence ou l'absence d'une personne dans une pièce et sur une direction de la personne par rapport au dispositif électrique, ainsi qu'un appareil de diffusion sonore comprenant : une pluralité de microphones qui collectent des sons périphériques ; un haut-parleur qui diffuse des sons ; un moyen de réception qui reçoit les informations d'état d'intérieur à partir du dispositif électrique ; et un dispositif de commande qui détermine une direction d'une source sonore par rapport à une position de référence en utilisant des informations sur les sons collectés par la pluralité de microphones. Le dispositif de commande comprend : un moyen de détermination qui détermine la direction de la personne par rapport à la position de référence en combinant les informations sur la direction de la source obtenue à partir des informations sur les sons collectés par la pluralité de microphones avec les informations d'état d'intérieur acquises à partir du dispositif électrique ; et un moyen de commande de diffusion sonore qui commande la diffusion sonore du haut-parleur en utilisant les informations sur la direction de la personne déterminée par le moyen de détermination.
