Linear vibrating motor with coil between a plurality of magnet modules and mass units

A linear vibrating motor, comprising:

• a housing comprising a bottom plate;
• a vibrator received in the housing and vibrating along a vibration direction parallel to the bottom plate;
• a stator comprising a coil and a coil support for supporting the coil;
• and
• an elastic part for suspending the vibrator in the housing;
• wherein the vibrator comprises a first side surface extending along the vibration direction, a second side surface extending along the vibration direction and opposite to the first side surface, and a groove through the first side surface and the second side surface;
• the coil support which is received in the housing comprises a supporting plate received in the groove and supporting the coil disposed in the groove, a pair of supporting arms extending to the bottom plate from two opposite ends of the supporting plate and facing the first and second side surfaces of the vibrator respectively, and a pair of supporting legs extending from ends of the supporting arms respectively and fixed on the bottom plate, the pair of supporting legs is opposite to the supporting plate, the vibrator is partially positioned between the pair of the supporting arms.
