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 () are symmetrically disposed at two ends of the vibrator; push-pull coils () 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.
