Linear vibration motor

A linear vibration motor, comprising a housing, a weight suspended in the housing, at least two driving assemblies driving the weight to horizontally vibrate, and an elastic connector elastically supporting the weight,

• wherein the weight comprises an inner wall enclosing to form a through hole, each of the at least two driving assemblies comprises a solenoid fixed to the housing and a magnet assembly fixed to the inner wall of the weight and vibrating together with the weight, the magnet assembly comprising first magnets arranged at two sides of the solenoid along a vibrating direction of the weight and first pole plates attached to outer sides of the first magnets, each of the at least two driving assemblies comprises two first magnets, the first magnets are magnetized along a direction perpendicular to the vibrating direction of the weight, the first magnets at the two sides of the solenoid have poles of a same polarity opposite to each other, each of the first pole plates comprises a common pole plate located between two adjacent solenoids and shared by two adjacent driving assemblies, two first magnets close to each other in the two adjacent driving assemblies are attached to two opposite surfaces of the common pole plate.
