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 disclosure can effectively reduce the static attraction force of the magnetic circuit, and increase the overall rigidity of the linear motor.

An actuator is provided. In order to reduce the planar area of an actuator, a first magnetic drive circuit and a third magnetic drive circuit that vibrate a movable body in an X direction with respect to a support are provided respectively on both sides, in a Z direction, of a second magnetic drive circuit that vibrates the movable body in a Y direction with respect to the support. The movable ranges, in the X direction and the Y direction, of the movable body with respect to the support are regulated by a stopper mechanism constituted between a first magnet and a first coil holder holding a first coil, a stopper mechanism constituted between a second magnet and a second coil holder holding a second coil, and a stopper mechanism constituted between a third magnet and a third coil holder holding a third coil.

The present disclosure discloses a feeding apparatus, which includes a motor, a driving unit, and a noise reduction module. The noise reduction module includes an audio receiving unit and a control unit. The audio receiving unit receives the sound generated by the feeding apparatus when the motor is running. The control unit is electronically connected to the driving unit and the audio receiving unit. The control unit sequentially supplies a plurality of motor drive data to the driving unit to drive the motor to run. The control unit sequentially receives a plurality of sound signals corresponding to those motor drive data from the audio receiving unit. The control unit analyzes the sound signals and selects one of the sound signals as an optimized sound signal. The control unit stores the motor drive data corresponding to the optimized sound signal as a setting motor drive data.
