Linear vibration motor

A linear vibration motor, comprising:

• a cabinet having a receiving space;
• a first magnet received in the accommodation space and fixed in the cabinet;
• a magnetic core fixed in the cabinet, opposite to the first magnet, with a coil winded on the magnetic core;
• a vibrating part received in the receiving space, suspended between the first magnet and the magnetic core;
• and
• a supporting part for suspending the vibrating part;
• the vibrating part comprising:
• a third magnet repulsing the first magnet;
• the coil having a changing current to magnetize the magnetic core to repulse with the third magnet to form a magnetic field to generate a force to drive the vibrating part to vibrate along a long axis direction between the first magnet and the magnetic core on which the coil is winded on;
• the cabinet comprising a bottom wall, a cover opposing the bottom wall and a side wall extending from the bottom wall towards the cover, the side wall surrounding the vibrating part and fixing to the cover, wherein the side wall comprising two opposing lateral sides on one of which the first magnet is fixed and on the other of which the magnetic core is fixed, and a connecting side connecting the one of the opposing lateral sides with the other of the opposing lateral sides, and the supporting part is fixed on the connecting side;
• the vibrating part keeping a distance with both the bottom wall and the cover, with neither directly nor indirectly contacting with the bottom wall and the cover.
