Title (EN) VEHICLE POWER SOURCE NOISE REDUCTION DEVICE
(FR) DISPOSITIF DE RÉDUCTION DE BRUIT DE SOURCE D'ALIMENTATION DE VÉHICULE
(JA) 車両動力源騒音低減装置
Abstract:
(EN) This vehicle power source noise reduction device: is to be arranged near an outer surface of a vehicle power source that is for driving a vehicle; reduces noise that is emitted from the vehicle power source; and comprises a plurality of speakers that include a sound wave generation unit that generates cancellation sound that is antiphase to the noise. Each of the plurality of speakers is arranged to emit the cancellation sound in a direction that is along the emission direction of the noise that is emitted from the vehicle power source.
(FR) L'invention concerne un dispositif de réduction de bruit de source d'alimentation de véhicule, lequel dispositif : doit être agencé à proximité d'une surface extérieure d'une source d'alimentation de véhicule qui est destinée à entraîner un véhicule ; réduit le bruit qui est émis à partir de la source d'alimentation de véhicule ; et comprend une pluralité de haut-parleurs qui comprennent une unité de génération d'ondes sonores qui génère un son d'annulation qui est en opposition de phase par rapport au bruit. Chaque haut-parleur de la pluralité de haut-parleurs est conçu pour émettre le son d'annulation dans une direction qui suit la direction d'émission du bruit émis à partir de la source d'alimentation de véhicule.
(JA) この車両動力源騒音低減装置は、車両を駆動させるための車両動力源の外表面近傍に配置され、車両動力源から放射される騒音を低減する、騒音とは逆位相のキャンセル音を発生させる音波発生部を含む複数のスピーカを備える。複数のスピーカは、各々、車両動力源から放射される騒音の放射方向に沿った方向にキャンセル音を放射するように配置されている。
