Abstract

A flat linear vibrating motor includes a cover, a base forming a receiving cavity together with the cover, a coil fixed on the base, an elastic member coupled to the base, a vibrator suspended in the cavity by the elastic member. The elastic member includes a mounting section coupled to the base, an arm extending from the mounting section, a free end extending from the arm, and a binder. The binder includes two plates for clamping the vibrator and a coupling section coupling the two plates for positioning the free end between the vibrator and the coupling section.

Claims (22)

1. A flat linear vibrating motor, comprising:

a cover;

a base forming a receiving cavity together with the cover;

a coil fixed on the base;

an elastic member comprising a mounting section coupled to one of the base and the cover, an arm extending from the mounting section, and a free end extending from the arm;

a vibrator suspended in the cavity by the elastic member for vibrating along a direction parallel to the base; wherein

the elastic member further comprises a binder including two plates for clamping the vibrator and a coupling section coupling the two plates for positioning the free end between the vibrator and the coupling section.

2. The flat linear vibrating motor as described in claim 1 comprising a magnet assembly and a weight coupled to the binder.

3. The flat linear vibrating motor as described in claim 2 , wherein the coil is located right below the magnet assembly.

4. The flat linear vibrating motor as described in claim 1 , wherein the arm connects to the mounting section by a U-shaped connecting part.

5. The flat linear vibrating motor as described in claim 1 comprising a plate between the cover and the vibrator.

6. A flat linear vibrating motor, comprising:

a cover;

a base forming a receiving cavity together with the cover;

a coil fixed on the base;

an elastic member comprising a mounting section coupled to one of the base and the cover, an arm extending from the mounting section, and a free end extending from the arm;

a vibrator suspended in the cavity by the elastic member for vibrating along a direction parallel to the base; wherein

the elastic member further comprises a binder including two plates for clamping the vibrator and a coupling section connecting the two plates, the coupling section overlapping the free end for pressing the free end on the vibrator.

7. The flat linear vibrating motor as described in claim 6 comprising a magnet assembly and a weight coupled to the binder.

8. The flat linear vibrating motor as described in claim 7 , wherein the coil is located right below the magnet assembly.

9. The flat linear vibrating motor as described in claim 6 , wherein the arm connects to the mounting section by a U-shaped connecting part.

10. The flat linear vibrating motor as described in claim 6 comprising a plate between the cover and the vibrator.
