Abstract
Official abstract text for this publication.
A linear vibrator includes a stator having a housing including a receiving space; a moveable unit received in the receiving space; an elastic member having one end connecting to the moveable unit and another end connecting to the stator for suspending the moveable unit in the receiving space; and a cushion arranged between the moveable unit and the housing, the cushion comprising a plurality of parts having different stiffness.
First claim
Opening claim text (preview).
What is claimed is: 1. A linear vibrator, comprising: a stator having a housing including a receiving space; a moveable unit received in the receiving space; an elastic member having one end connecting to the moveable unit and another end connecting to the stator for suspending the moveable unit in the receiving space; a cushion arranged between the moveable unit and the housing, the cushion comprising a plurality of parts having different stiffness, wherein the cushion includes a through hole therein, the through hole passes through at least two different stiffness parts. 2. The linear vibrator as described in claim 1 , wherein the parts are arranged in an order that the stiffness thereof increase gradually. 3. The linear vibrator as described in claim 1 , wherein the parts are arranged in an order that the stiffness thereof increase gradually and then decrease gradually. 4. The linear vibrator as described in claim 1 , wherein the cushion is positioned by the housing, and a part thereof having a relatively lower stiffness faces the moveable unit. 5. The linear vibrator as described in claim 1 , wherein the cushion is arranged on the moveable unit, and a part thereof having a relatively lower stiffness faces the housing. 6. The linear vibrator as described in claim 1 , wherein the elastic member includes a first elastic arm connecting to the moveable unit, a second elastic arm connecting to the stator, and a third elastic arm connecting the first elastic arm to the second elastic arm. 7. The linear vibrator as described in claim 6 further comprising a gasket disposed on the first elastic arm or the second elastic arm. 8. The linear vibrator as described in claim 6 , wherein the third elastic arm comprises a deforming part and a damping member attached to the deforming part.
