Title: LINEAR VIBRATION MOTOR
Abstract:
A linear vibration motor, comprising a housing, a stator, a vibrator (20), and elastic support members (40a) located at both ends of the vibrator and used for supporting the vibrator and providing elastic restoring forces. Each elastic support member comprises two elastic arms (401a, 401c). Connection portions (402a, 403a, 402c, 403c) are provided at both ends of each elastic arm on the same side, respectively. Two connection portions of the two elastic arms are combined together at one end. The two elastic arms transversely extend towards the directions in which respective connection portions face to form a transverse cross structure. The two connection portions at the other ends of the two elastic arms are combined with the vibrator and the housing, separately. The vibration space, occupied by the elastic support members, of the vibrator is relatively small, the resonance frequency of the vibration motor is reduced, and the low frequency performance of the vibration motor is improved.
