Title
(EN) VIBRATION GENERATION DEVICE
(FR) DISPOSITIF DE GÉNÉRATION DE VIBRATIONS
(JA) 振動生成装置
Abstract
(EN)
A vibration generation device has a case, a vibration plate that is supported in the case and that generates sound by vibrating in a first direction, and a vibration imparting unit that is mounted in the case and that vibrates the case. The vibration imparting unit vibrates the case in the first direction at a first frequency and vibrates the case in a second direction at a second frequency that is lower than the first frequency.
(FR)
Un dispositif de génération de vibrations comprend un boîtier, une plaque de vibration qui est supportée dans le boîtier et qui génère un son par vibration dans une première direction, et une unité de transmission de vibrations qui est montée dans le boîtier et qui fait vibrer le boîtier. L'unité de transmission de vibrations fait vibrer le boîtier dans la première direction à une première fréquence et fait vibrer le boîtier dans une seconde direction à une seconde fréquence qui est inférieure à la première fréquence.
(JA)
振動生成装置は、筐体と、前記筐体に支持され、第1の方向に振動することで音を発生する振動板と、前記筐体に取り付けられ、前記筐体を振動させる振動付与部と、を有し、前記振動付与部は、前記筐体を前記第1の方向に第1の周波数で振動させ、前記筐体を第2の方向に前記第1の周波数より低い第2の周波数で振動させる。
