LINEAR VIBRATION MOTOR

A linear vibration motor, comprising a housing (1), a mass block (31) suspended in the housing, driving assemblies for driving the mass block (31) to vibrate, and an elastic connecting member (4) for elastically supporting the mass block (31). The mass block (31) comprises an inner wall (312) defining a through hole (311); at least two driving assemblies are provided, and each driving assembly comprises a solenoid (21) fixed to the housing (1) and a steel magnet assembly (32) fixed on the inner wall (312) of the mass block (31); the steel magnet assembly (32) comprises first steel magnets (321) provided on two sides of the solenoid (21) in the vibration direction of the mass block (31); the first steel magnets (321) are magnetized in a direction perpendicular to the vibration direction; the same poles of the first steel magnets (321) on the two sides of the solenoid (21) are arranged opposite to each other; the first steel magnets (321) comprise a common steel magnet (3210) located between two adjacent soleno
