Abstract

A linear vibrator includes a housing with an accommodation space; a vibrating part received in the accommodating space; and a plurality of elastic members for suspending and supporting the vibrating part in the housing. The elastic member includes two holding parts connecting to the housing and the vibrating part respectively. The holding part includes a first end part and the second end part away from the first end. An interconnecting part is provided to connect the two holding parts, and includes a main body part and bending parts extending from two ends of the main body part respectively. The bending part includes a first arc part, and a second arc part extending from the first arc part, a bending direction of the first arc part being contrary to a bending direction of the second arc part.

First claim

What is claimed is:

1 . A linear vibrator, comprising:
a housing with an accommodation space; a vibrating part received in the accommodating space; a plurality of elastic members for suspending and supporting the vibrating part in the housing, the elastic member including:
two holding parts connecting to the housing and the vibrating part respectively, the holding part comprising a first end part and a second end part away from the first end;
an interconnecting part connecting the two holding parts, the interconnecting part including a main body part and bending parts extending from two ends of the main body part respectively, the bending part including a first arc part connecting with the holding part and away from the first end part toward the second end part, and a second arc part extending from the first arc part and connecting with the mentioned main body, a bending direction of the first arc part being contrary to a bending direction of the second arc part.

2 . The linear vibrator as described in claim 1 , wherein the first arc part includes a convex semi-circle with one end connecting with the first end part, and a linear segment extending from the other end of the convex semi-circle toward the second end part, the second arc part includes a concave semi-circle connected with the linear segment and the linear segment extending from one end of the concave semi-circle arc toward the main body.

3 . The linear vibrator as described in claim 2 , wherein a radius of curvature of the convex semi-circle is equal to that of the concave semi-circle.

4 . The linear vibrator as described in claim 1 , wherein the main body is arc-shaped and a bending direction of the main body is opposed to a bending direction of the second arc-shaped part.

5 . The linear vibrator as described in claim 4 , wherein a radius of curvature of the main body is greater than that of the first arc part or the second arc part.

6 . The linear vibrator as described in claim 1 , wherein the bending part is arranged symmetrically at two ends of the main body.
