Title
(EN) BROADBAND ACTUATOR
(FR) ACTIONNEUR À LARGE BANDE
(KO) 광대역 액추에이터
Abstract
(EN)
A broadband actuator according to an embodiment may comprise: a cylindrical housing having an inner space; a yoke member installed in the inner space and provided with a cylindrical inner yoke that protrudes upward from the center of the lower side of the inner space; a hollow radial magnet installed to surround the outer circumferential surface of the inner yoke; a moving body provided with a cylindrical mass installed to surround the outer circumferential surface of the radial magnet, and provided with a coil part installed along the circumference of the mass; and an elastic member elastically supporting the moving body from one side of the inner space.
(FR)
Un actionneur à large bande selon un mode de réalisation de la présente invention peut comprendre : un boîtier cylindrique ayant un espace interne ; un élément de culasse installé dans l'espace interne et pourvu d'une culasse interne cylindrique qui fait saillie vers le haut à partir du centre du côté inférieur de l'espace interne ; un aimant radial creux installé de façon à entourer la surface circonférentielle externe de la culasse interne ; un corps mobile pourvu d'une masse cylindrique installée de façon à entourer la surface circonférentielle externe de l'aimant radial, et pourvu d'une partie de bobine installée le long de la circonférence de la masse ; et un élément élastique soutenant élastiquement le corps mobile d'un côté de l'espace interne.
