Linear vibration motor

A linear vibration motor, comprising:

• a movable part, a suspension device, and a fixed part;
• wherein the movable part further comprising at least one magnet set, the magnet set comprising at least three magnets arranged spaced apart, the magnets having an up-and-down magnetization direction, the adjacent magnets having opposite polarities when arranged;
• the fixed part at least comprising:
• a coil, at least one magnetically conductive element, and a housing;
• the magnet set of the movable part and the coil and the magnetically conductive element of the fixed part being arranged opposite to each other with a gap, both polar surfaces at both sides of the magnet set being facing opposite to the coil and the magnetically conductive element of the fixed part, and the size of the magnetically conductive element of the fixed part in the non-moving direction being greater than the size of the magnet set in the non-moving direction;
• the at least one magnetically conductive element being located above or below the magnet set;
• when the number of the at least one magnetically conductive element exceeding one, the magnetically conductive element being respectively arranged above and below the magnet set;
• the suspension device comprising two elastic stripes respectively located on both sides of the movable part, with one side of each elastic stripe connected to the movable part and the other side connected to the fixed part so that the movable part being supported by the suspension device and able to move freely relative to the fixed part;
• each of connecting ends of the elastic stripe having a height the same as the heights of the connecting ends of the movable part and the fixed part so that the suspension device staying in a straight and flat shape without bending at both connecting ends.
