Abstract

A linear vibrating motor includes a base defining a first bottom wall and a first sidewall extending vertically from the first bottom wall, a cover forming a receiving cavity together with the base and defining a second bottom wall and a second sidewall extending vertically from the second bottom wall, a coil positioned on one of the first bottom wall and the second bottom wall, a vibrating unit suspended in the receiving cavity, a gasket positioned on a bottom wall of one of the base and the cover, and an elastic plate suspending the vibrating unit and sandwiched between the gasket and a sidewall of the other one of the base and the cover.

Claims (14)

1. A linear vibrating motor, comprising:

a base defining a first bottom wall and a first sidewall extending vertically from the first bottom wall;

a cover forming a receiving cavity together with the base, the cover including a second bottom wall and a second sidewall extending vertically from the second bottom wall;

a coil positioned on one of the first bottom wall and the second bottom wall;

a vibrating unit suspended in the receiving cavity;

a gasket positioned on a bottom wall of one of the base and the cover; and

an elastic plate suspending the vibrating unit and being sandwiched between the gasket and a sidewall of the other one of the base and the cover.

2. The linear vibrating motor as described in claim 1 , wherein one of the first sidewall and the second sidewall wraps the other one.

3. The linear vibrating motor as described in claim 1 , wherein the vibrating unit locates fully above the elastic plate.

4. The linear vibrating motor as described in claim 1 , wherein the vibrating unit comprises a weight sitting on the elastic plate.

5. The linear vibrating motor as described in claim 4 , wherein the weight defines a bevel extending from a first bottom surface sitting on the elastic plate and the bevel forms an acute angle with the elastic plate.

6. The linear vibrating motor as described in claim 5 , wherein the weight further defines a second bottom surface far away from the elastic plate 14 for forming a depression therebetween.

7. The linear vibrating motor as described in claim 1 further comprising a first rubber on the first bottom wall.

8. The linear vibrating motor as described in claim 7 further comprising a second rubber on the second bottom wall.
