Title (EN) ULTRASONIC WAVE OUTPUT DEVICE AND SOUND GENERATION CONTROL METHOD
(FR) DISPOSITIF D'ÉMISSION D'ONDES ULTRASONORES ET PROCÉDÉ DE COMMANDE DE GÉNÉRATION DE SON
(JA) 超音波出力装置、および発音制御方法
Abstract:
(EN) Ultrasonic wave output devices (1, 2) according to the present disclosure are provided with: a plurality of ultrasonic speakers (22A, 22B); sound generation-setting units (17: S140, S150, S160); and signal-providing units (18: S150, S160). The plurality of ultrasonic speakers are configured to output ultrasonic waves in the same direction. The sound generation-setting units are configured to: acquire a distance signal that indicates a signal determined by the distance that is required to be reached by a sound wave; and set at least one sound-generating speaker, which indicates a sound-generating ultrasonic speaker among the plurality of ultrasonic speakers, so that the number of the ultrasonic speakers generating sound increases as the distance to be reached indicated by the distance signal increases. The signal-providing units are configured to provide a sound wave signal to the at least one sound-generating speaker so that the sound-generating speaker outputs ultrasonic waves.
(FR) La présente invention concerne des dispositifs d'émission d'ondes ultrasonores (1, 2) comprenant : une pluralité de haut-parleurs à ultrasons (22A, 22B) ; des unités de réglage de génération de son (17 : S140, S150, S160) ; et des unités de fourniture de signal (18 : S150, S160). La pluralité de haut-parleurs à ultrasons est conçue pour émettre des ondes ultrasonores dans la même direction. Les unités de réglage de génération de son sont conçues pour : acquérir un signal de distance qui indique un signal déterminé par la distance devant être atteinte par une onde sonore ; et régler au moins un haut-parleur de génération de son indiquant un haut-parleur à ultrasons de génération de son parmi la pluralité de haut-parleurs à ultrasons, de telle sorte que le nombre de haut-parleurs à ultrasons générant un son augmente à mesure que la distance à atteindre indiquée par le signal de distance augmente. Les unités de fourniture de signal sont conçues pour fournir un signal d'onde sonore auxdits haut-parleurs de génération de son de telle sorte que le haut-parleur de génération de son émette des ondes ultrasonores.
(JA) 本開示の超音波出力装置(1,2)は、複数の超音波スピーカ(22A,22B)と、発音設定部(17:S140、S150、S160)と、信号提供部(18:S150、S160)と、を備える。複数の超音波スピーカは、超音波を同方向に出力するように構成される。発音設定部は、要求される音波の到達距離に応じた信号を表す距離信号を取得し、該距離信号が示す到達距離が大きくなるにつれて発音させる超音波スピーカが多くなるように、複数の超音波スピーカのうちの発音させる超音波スピーカを表す少なくとも1つの発音スピーカを設定するように構成される。信号提供部は、少なくとも1つの発音スピーカに対して、該発音スピーカに超音波を出力させるための音波信号を提供するように構成される。
