Kind Code:
A1
Abstract:
A motor, comprising a housing having an accommodating space and a vibrator and a stator which are accommodated in the accommodating space. One of the vibrator and the stator comprises a magnetic circuit structure, and the other one comprises a coil assembly; the coil assembly comprises an iron core and a first driving coil and a second driving coil which are respectively sleeved on two ends of the iron core along the vibration direction of the vibrator, and the energizing directions of the first driving coil and the second driving coil are opposite; the magnetic circuit structure comprises first magnetic steels disposed on two sides of the first driving coil along a direction perpendicular to the vibration direction and having the same poles being opposite to each other and second magnetic steels disposed on two sides of the second driving coil along the direction perpendicular to the vibration direction and having the same poles being opposite to each other, and the first magnetic steel and the second magnetic steel located on the same side of the coil assembly are both magnetized along the direction perpendicular to the vibration direction; the magnetizing directions of the first magnetic steel and the second magnetic steel located on the same side of the coil assembly are opposite. The directions of Lorentz magnetic forces applied to the first driving coil and the second driving coil are the same, so that the motor vibration effect can be improved.
