Abstract: A linear vibration motor comprising a housing, a vibrator, and a stator fixed on the housing and arranged parallel to the vibrator, push-pull magnets (4) are symmetrically disposed at two ends of the vibrator; push-pull coils (2) surrounding the push-pull magnets are fixedly disposed on the housing at positions corresponding to the push-pull magnets; after the push-pull coils are energized, the push-pull coils and the push-pull magnets generate push-pull forces in a horizontal direction, which provides a driving force for the reciprocating motion of the vibrator in a direction parallel to the plane in which the stator is located. The push-pull structure provides push-pull force for the reciprocation motion of the vibrator, so that an intense vibration force can be achieved.

Abstract: A self-adaptive control miniature motor comprises a driving unit (200), a mover (300) and a self-adaptive control unit (100). The driving unit comprises a fixed stator and a movable vibration block, and provides the driving force for the reciprocating motion of the mover through the interaction between the stator and the vibration block. The mover is a forced vibration part, and is driven by the movable vibration block of the driving unit to do the reciprocating motion. The self-adaptive control unit is used for controlling a motion state of the mover in real time by adjusting a force applied on the mover, based on a feedback information of the motion state of the mover. The self-adaptive control miniature motor, by combining the motor hardware with a control circuit, facilitates real-time adjustment of the magnetic field intensity in the motor, thus improving the stability of the vibration of the motor.
