Abstract
The present disclosure provides a linear motor including: a housing body with a containment space; a vibrator assembly suspended in the containment space by an elastic member for vibrating along a vibration direction; a stator assembly fixedly connected to the housing body and having a magnetic axis along the vibration direction; and two magnets located on both sides of the magnetic axis and spaced from the stator assembly, including a first magnet section and a second magnet section located on both sides of the first magnet section. A magnetic field strength of the first magnet section along the magnetic axis is greater than a magnetic field strength of the second magnet section along the magnetic axis. The configuration of the invention can effectively reduce the static attraction force of the magnetic circuit, and increase the overall rigidity of the linear motor.
