Abstract
(EN)
Provided is a vibration actuator the amplitude of which is increased without reducing the number and width of arms, even in a structure that supports a magnetic circuit section by a single suspension. Both increased amplitude and stabilized vibrating properties are achieved by using a structure in which the middle part of each arm of a suspension is provided with a bent portion in the planar direction, and the metal fatigue of the suspension produced when vibrating is reduced by incorporating the suspension in a state in which the suspension is deformed in advance in an expansion/contraction direction (i.e. the vibrating direction of said magnetic circuit section). Additionally, these advantages, which extend the life of the whole component, allow the component to be environmentally friendly.

La présente invention se rapporte à un actionneur à vibration dont l'amplitude augmente sans réduire le nombre et la largeur de bras, même dans une structure qui soutient une section circuit magnétique par une simple suspension. Les propriétés d'amplitude augmentée et de vibration stabilisée sont obtenues à l'aide d'une structure dans laquelle la partie intermédiaire de chaque bras d'une suspension est pourvue d'une partie incurvée dans la direction plane, et la fatigue du métal de la suspension produite lors de la vibration est réduite grâce à l'incorporation de la suspension dans un état dans lequel la suspension est déformée préalablement dans une direction de dilatation/contraction (c'est-à-dire, la direction de vibration de ladite section de circuit magnétique). De plus, ces avantages, qui prolongent la durée de vie de tout le composant, permettent au composant de respecter l'environnement.

【課題】 サスペンション1枚で磁気回路部を支持する構造でもアームの本数と幅を減らす事無く振幅を拡大することの出来る振動アクチュエータを提供する。 【解決手段】 サスペンションのアーム中間部に平面方向の折れ曲がり部を設けた構造とすることで、振幅の増加と振動特性の安定化とを両立し、予めサスペンションを前記磁気回路部の振動方向である伸縮方向に変形した状態で組み込むことにより、振動時に生じるサスペンションの金属疲労を軽減することが可能となった。加えて、これらの効果による部品全体での長寿命化によって自然環境に配慮した部品とすることができた。
