Abstract: The vibrator comprises a vibration block, and the vibration block comprises at least one permanent magnet, the stator comprises conductive blocks, and the conductive blocks are subjected to the effect of a magnetic field force which is the same as and/or opposite to the vibration direction of the vibrator. When the vibrator is in a balanced state, the resultant force of the magnetic field force is zero. When the magnetic conductive blocks are subjected to the effect of an excitation force to perform a relative displacement relative to the vibrator in the vibration direction of the vibrator, a direction of the resultant force of the magnetic field forces is the same as the direction of the relative displacement, a magnitude of the resultant force of the magnetic field forces has a proportional relationship with a magnitude of the relative displacement. The conductive blocks are used to replace the stator coils.

Abstract: A linear vibration motor comprising a vibrator and a stator, wherein the vibrator comprises at least two permanent magnets disposed adjacent to each other and a magnetic yoke disposed between any two adjacent permanent magnets, and adjacent ends of the two adjacent permanent magnets have the same polarities; the stator comprises coils and magnetic cores disposed in the coils; magnetization directions of the permanent magnets are perpendicular to axis directions of the coils. The linear vibration motor enables the magnetic lines of flux of the permanent magnets to intensively pass through the coils by means of a repulsive force between two ends with same polarity of two permanent magnets so as to obtain a larger magnetic flux and a stronger vibration sensing effect.

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.
