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.
