Abstract
(EN)
The present invention relates to a loudspeaker box control method and device. The method comprises: when a loudspeaker box is in a standby state, emitting an ultrasonic signal, and receiving a reflected ultrasonic signal reflected by an external object; obtaining a motion trajectory of the external object according to the reflected ultrasonic signal; and determining, according to the motion trajectory of the external object, a target operation instruction needing to be executed. According to the technical solutions, by using the loudspeaker box, a user can control the loudspeaker box only by limb actions without the need of an external active remote controller, and thus the convenience of the user to control the loudspeaker box is improved. Meanwhile, the loudspeaker box can transmit an ultrasonic wave by means of a built-in speaker and receive the reflected ultrasonic signal reflected by the external object by means of a built-in microphone, i.e., the user can control the loudspeaker box without mounting additional equipment on the loudspeaker box, and the costs of loudspeaker box control are reduced.

La présente invention porte sur un procédé et sur un dispositif de commande de boîtier de haut-parleur. Le procédé consiste : lorsqu’un boîtier de haut-parleur se trouve dans un état de veille, à émettre un signal ultrasonore, et à recevoir un signal ultrasonore réfléchi qui est réfléchi par un objet externe ; à obtenir une trajectoire de déplacement de l’objet externe en fonction du signal ultrasonore réfléchi ; et à déterminer, en fonction de la trajectoire de déplacement de l’objet externe, une instruction d’opération de cible devant être exécutée. Selon la solution technique, en utilisant le boîtier de haut-parleur, un utilisateur peut ne commander le boîtier de haut-parleur que par des actions de ses membres sans avoir besoin d’une télécommande active externe, et ainsi l’ergonomie pour l’utilisateur de commande du boîtier de haut-parleur est améliorée. En même temps, le haut-parleur peut émettre une onde ultrasonore au moyen d’un haut-parleur intégré et recevoir le signal ultrasonore réfléchi par l’objet externe au moyen d’un microphone intégré, c.-à-d., l’utilisateur peut commander le boîtier de haut-parleur sans monter d’équipement additionnel sur le boîtier de haut-parleur, et les coûts de commande de boîtier de haut-parleur sont réduits.

本公开是关于一种音箱控制方法及装置。该方法包括:在音箱处于待机状态时,发出超声波信号,并接收经过外界物体反射后的反射超声波信号;根据反射超声波信号,获取外界物体的运动轨迹;根据外界物体的运动轨迹,确定需要执行的目标操作指令。该技术方案中,音箱可以使得用户在不需要外部有源遥控器的情况下仅通过肢体动作即可实现对音箱的控制,提高了用户控制音箱的便捷性。同时音箱可以通过自带的扬声器发送超声波,并通过自带的麦克风接收经外界物体反射后的反射超声波信号,即用户对音箱的控制不需要在音箱上加入额外的设备,降低了音箱控制的成本。
