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.
