Abstract: A linear vibration motor comprising a housing, a vibrator, and a stator fixed on the housing and arranged parallel to the vibrator, push-pull magnets (4) are symmetrically disposed at two ends of the vibrator; push-pull coils (2) surrounding the push-pull magnets are fixedly disposed on the housing at positions corresponding to the push-pull magnets; after the push-pull coils are energized, the push-pull coils and the push-pull magnets generate push-pull forces in a horizontal direction, which provides a driving force for the reciprocating motion of the vibrator in a direction parallel to the plane in which the stator is located. The push-pull structure provides push-pull force for the reciprocation motion of the vibrator, so that an intense vibration force can be achieved.

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.

Abstract: Disclosed is a linear vibration motor comprising 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. The vibration block comprises at least two permanent magnets. The stator comprises a coil. A magnetic conductive core is arranged in the coil. The adjacent end surfaces of the at least two adjacent permanent magnets form slopes parallel to each other. The slopes form an acute angle with the axis of the magnetic conductive core. The slopes extend obliquely in the direction approaching the corresponding magnetic conductive core. The motor not only ensures the maximization of the sizes of the permanent magnets, but also increases the effective magnetic field intensity between a gap between the adjacent permanent magnets and the magnetic conductive core, thus increasing a driving force driving the vibrator into vibration.
