  • Patent number: 10944313
    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.

  • Patent number: 10666121
    Abstract: A linear vibration motor comprises a vibrator and a stator arranged parallel to the vibrator. The vibrator comprises a counterweight block and a vibration block embedded and fixed in the counterweight block. Permanent magnets in the vibration block and electromagnets in the stator generate the push-pull forces acting on each other. The electromagnets in the stator generates a variable magnetic field after being energized, and drives the vibrator to move reciprocally along the direction parallel to the plane in which the stator is located by changing the direction of the magnetic field lines of the magnetic field. With the repulsive force between two ends the permanent magnets having the same polarity, the linear vibration motor allows the magnetic field lines of the permanent magnets to concentratedly pass through coils, thus obtaining a larger magnetic flux and a stronger vibration effect.
