Abstract
(EN)
The present invention is configured such that, a ring member is bonded to a cone section formed on the outer circumference of a vibration plate body, and the inner circumferential section of an edge is bonded to the outer circumference section of the ring member or the cone section. Thus, the stiffness is increased without requiring a change in the shape of the vibration plate body, that is, the stiffness is improved without causing an increase in the weight of the vibration plate body, and a degradation in acoustic pressure at high frequencies is prevented.
(FR)
La présente invention est configurée de telle sorte que, un élément annulaire est lié à une section conique formée sur la circonférence externe d'un corps de plaque vibrante, et la section circonférentielle interne d'un bord est liée à la section de circonférence externe de l'élément annulaire ou de la section de cône. Ainsi, la rigidité est augmentée sans nécessiter un changement de la forme du corps de plaque vibrante, c'est-à-dire, la rigidité est améliorée sans provoquer une augmentation du poids du corps de plaque de vibration, et une dégradation de la pression acoustique à des fréquences élevées est évitée.
(JA)
振動板本体の外周に形成されたコーン部にリング部材を接合し、リング部材又はコーン部の外周部にエッジの内周部を接合した構成とし、振動板本体の形状変更を要せず剛性を高め、つまり振動板本体の重量増加を招来することなく剛性を向上させ、高域での音圧低下を防止した。
