Vibration motor
A vibration motor is disclosed. The vibration motor includes a housing; an elastic connecting piece accommodated in the housing; a fixed component; and a vibrating component suspended in the housing by the elastic connecting piece. One of the fixed component and the vibrating component includes a coil, and the other including a magnet. The vibration motor further includes a damping piece integrated with the elastic connecting piece.
1. A vibration motor comprising:
a housing;
an elastic connecting piece accommodated in the housing;
a fixed component;
a vibrating component suspended in the housing by the elastic connecting piece;
one of the fixed component and the vibrating component including a coil, and the other one of the fixed component and the vibrating component including a magnet; and
a damping piece integrated with the elastic connecting piece, wherein the elastic connecting piece comprises a first connecting part connecting with the vibrating component, a second connecting part connecting with the housing, and a middle connecting part connecting the first connecting part with the second connecting part, the damping piece is coated in a periphery of the middle connecting part.
2. The vibration motor as described in claim 1 , wherein the damping piece is made of silica gel.
3. The vibration motor as described in claim 1 , wherein the damping piece is formed on the elastic connecting piece by injection or extrusion.
4. The vibration motor as described in claim 1 , wherein the damping piece is integrated on a surface of the middle connecting facing the vibrating component, and an adhesive layer is arranged between the damping piece and the middle connecting part.
5. The vibration motor as described in claim 4 , wherein the adhesive layer is a two-sided adhesive layer, a resin adhesive layer or a back adhesive layer.
6. The vibration motor as described in claim 1 , wherein the elastic connecting piece comprises a first connecting arm and a second connecting arm, wherein the first connecting arm is interconnected with one side of the second connecting arm, and an elastic deformation gap is formed to each other at the other side.
7. The vibration motor as described in claim 6 , wherein the damping piece is coated in a periphery of the elastic connecting piece, and full of the elastic deformation gap.
8. The vibration motor as described in claim 6 , wherein the damping piece is coated in a periphery of the first connecting arm or the second connecting arm.
9. The vibration motor as described in claim 6 , wherein an amount of the damping piece is two, and the two damping pieces coat parts of the first connecting arm and the connecting arm respectively, further the two damping pieces are separated from each other.
