Vibration motor

1. A vibration motor comprising:

a housing;

a fixed component;

an elastic connecting piece;

a vibrating component comprising a counterweight suspended by the elastic connecting piece; one of the fixed component and the vibrating component comprising a coil, and the other comprising a magnet;

a damping piece fixed on the counterweight and facing the elastic connecting piece; wherein

one of the counterweight and the damping piece is provided with a slot and a glue dispersing slot connecting with the slot, and a projecting part formed on the other of the counterweight and the damping piece for matching with the slot.

2. The vibration motor as described in claim 1 , wherein the housing comprises a housing body and a cover plate covering the housing body; the side of the counterweight, facing the elastic connecting piece, is provided with a first end surface and a second end surface parallel with the cover plate and arranged oppositely; and the glue dispensing slot extends the direction pointing to the second end surface from the first end surface of the counterweight and extends toward the geometrical center of the counterweight from the first end surface.

3. The vibration motor as described in claim 2 , wherein a convex edge is also formed on the side on the counterweight, facing the elastic connecting piece in the extending and extruding way, further the convex edge is formed from the second end surface along the direction close to the elastic connecting piece in the extending and extruding way.

4. The vibration motor as described in claim 3 , wherein the surface of the convex edge facing the first end surface serves as a carrying surface; the damping piece is carried by carrying surface; and the shape of the carrying surface is matched with the contact surface corresponding to the damping piece.

5. The vibration motor as described in claim 2 , wherein the first end surface is the end surface close to the cover plate on the counterweight.

6. The vibration motor as described in claim 2 , wherein the elastic connecting piece comprises a first connecting part connecting with the counterweight, a second connecting part connecting with the housing body of the housing and a middle connecting part connecting the first connecting part with the second connecting part; and the vibration motor also comprises at least a spacer which is arranged on the first connecting part and/or the second connecting part.

7. The vibration motor as described in claim 6 , wherein one side of the damping piece is inserted into the counterweight, and the other side thereof is connected with the side of the middle connecting part facing the counterweight.

8. The vibration motor as described in claim 6 , wherein one side of the damping piece is inserted into the counterweight, and the other side thereof is connected with the housing body after coating the middle connecting part.

9. The vibration motor as described in claim 2 , wherein the housing comprises the cover plate on which the fixed component is fixed; the vibrating component comprises the magnet and a pole plate, wherein the magnet is accommodated in the counterweight, and the pole plate is adhered to the end surface of the counterweight far away from the cover plate.

10. The vibration motor as described in claim 1 , wherein the housing comprises a housing body and a cover plate covering the housing body; the damping piece has a third end surface and a fourth end surface parallel with the cover plate and arranged oppositely; and the glue dispensing slot extends along the fourth end surface from the third end surface of the damping piece and extends toward the geometrical center of the damping piece from the third end surface.
