Title
(EN) SUPPORT STRUCTURE OF VIBRATOR SPEAKER UNIT
(FR) STRUCTURE DE SUPPORT D'UNITÉ DE HAUT-PARLEUR À VIBREUR
(KO) 진동자 스피커 유닛의 지지구조
Abstract
(EN)
A vibrator unit is supported by means of a plurality of springs instead of being fixed directly to a housing, a platform portion supports the vibrator unit and pushes same toward the front which is the vibrator tip direction, the platform portion is supported by means of springs in both directions and stays in a floating state, and all constituent elements surrounding the vibrator unit form a supporting structure by being fixed to only the front part of the housing. Therefore, the present invention allows wider vibration width, and the contact state of the vibrator tip is retained in a wide frequency band. Movable elements are disposed so as to move toward the back, and nonlinear conical springs are applied as the compressed springs and thus quickly attenuate the vibration toward the back. Therefore, the vibration, other than the vibration for exciting an external medium for generating sounds, leaking toward the back is suppressed.

Selon la présente invention, une unité de vibreur est soutenue au moyen d'une pluralité de ressorts au lieu d'être fixée directement à un boîtier, une partie de plateforme soutient l'unité de vibreur et la pousse vers l'avant, qui représente la direction de pointe de vibrateur, la partie plateforme est soutenue au moyen de ressorts dans les deux directions et reste dans un état flottant, et tous les éléments constitutifs entourant l'unité de vibreur forment une structure de support en étant fixés uniquement à la partie avant du boîtier. Par conséquent, la présente invention permet une plus grande largeur de vibration, et l'état de contact de la pointe de vibreur est retenu dans une large bande de fréquences. Des éléments mobiles sont disposés de manière à se déplacer vers l'arrière, et des ressorts coniques non linéaires sont appliqués comme ressorts comprimés et atténuent ainsi rapidement la vibration vers l'arrière. Par conséquent, la vibration s'échappant vers l'arrière, autre que la vibration destinée à exciter un milieu externe pour générer des sons, est supprimée.

본 발명은 진동자 유닛을 하우징에 직접 고정하는 방식이 아니라, 복수의 스프링에 지지된 형태로 구성하고, 플랫폼부가 진동자 유닛을 지지하여 진동자 팁 방향인 전방을 향해 밀도록 구성하고, 플랫폼부는 양방향으로 스프링에 의해 지지되어 플로팅(floating) 상태가 되며, 진동자 유닛을 둘러싼 모든 구성 요소는 하우징의 전방부에만 고정되도록 형성되는 지지구조를 가짐으로써, 보다 넓은 진동폭을 허용할 수 있으며 넓은 주파수 대역에서 진동자 팁의 접촉 상태가 유지되는 것이 특징이다. 또한, 이동 가능한 요소들이 후방으로 이동하는 방향에 배치되어 압축되는 스프링은 비선형 콘형 스프링(conical spring)을 적용하여 후방을 향하는 진동을 빠르게 감쇠시켜 음향을 발생시키는 외부 매체를 가진하기 위한 진동 이외의 후방으로 누설되는 진동을 억제하는 것이 특징이다.
