Title:
LINEAR VIBRATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2017/088359
Kind Code:
A1
Abstract:
A linear vibration motor, comprising a shell, a vibrator and a stator fixed on the shell and arranged in parallel with the vibrator; push-pull magnets (4) being symmetrically provided at two ends of the vibrator; push-pull coils (2) which surround the push-pull magnets being fixedly disposed on the shell in positions corresponding to the push-pull magnets; after being connected to power, the push-pull coils working with the push-pull magnets to generate a push-pull force in a horizontal direction, which provides a driving force for the reciprocating movement of the vibrator in a direction parallel to the plane of the stator. By virtue of the push-pull structure, a push-pull force is provided for the reciprocating movement of the vibrator, such that a strong vibration effect can be achieved.
