Linear motor

A linear motor, comprising a housing with a receiving space, and a vibrator assembly, a stator assembly and an elastic assembly received in the receiving space,

• wherein the elastic assembly is configured to suspend and support the vibrator assembly in the receiving space;
• wherein the vibrator assembly comprises a central magnet portion;
• the stator assembly comprises a coil portion and auxiliary magnet portions that are arranged along a first direction, the coil portion is sleeved on a middle portion of an outer periphery of the central magnet portion, two ends of the central magnet portion are provided with the auxiliary magnet portions, respectively, the coil portion, when energized, drives the vibrator assembly to vibrate along the first direction, and the auxiliary magnet portions and the elastic assembly jointly provide a restoring force for the vibrator assembly to reciprocate along the first direction;
• and
• wherein one of the auxiliary magnet portions comprises a first auxiliary magnet group and/or a second auxiliary magnet group, the first auxiliary magnet group comprises two first auxiliary magnets arranged along a second direction and provided on two sides of each end of the central magnet portion, respectively;
• the second auxiliary magnet group comprises two second auxiliary magnets arranged along a third direction and provided on two sides of each end of the central magnet portion, respectively;
• wherein the first direction, the second direction and the third direction are arranged perpendicularly to one another.
