Title:
LINEAR VIBRATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2018/036054
Kind Code:
A1
Abstract:
A linear vibration motor, comprising: a housing, a vibration assembly and a stator assembly; the vibration assembly includes a mass (1), a permanent magnet (2) and an elastic sheet (3); the stator assembly comprises a coil (4) and a damping member (5), the damping member (5) comprising a main body (51) and an elastic arm (52) extending from the main body; the main body (51) is fixed to an end portion of the mass (1) in the longitudinal direction; the elastic sheet (3) has a middle arm (31) and a first connecting arm (32) and a second connecting arm (33) respectively disposed at both ends of the middle arm (31); a surface of the middle arm (31) that is close to the mass (1) abuts against the elastic arm (52); the first connecting arm (32) is fixedly connected to the housing, and the second connecting arm (33) is fixedly connected to the mass (1). The damping member of the linear vibration motor is simple to assemble, has a easily controllable assembling process, and would not easily lose effectiveness.
