Abstract
A linear vibration motor, including 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. The weight includes an inner wall enclosing to form a through hole, each driving assembly includes a solenoid fixed to the housing and a magnet assembly fixed to the inner wall, the magnet assembly includes first magnets arranged at two sides of the solenoid along a vibrating direction of the weight, the first magnets are magnetized along a direction perpendicular to the vibrating direction, the first magnets at two sides of the solenoid have poles of a same polarity opposite to each other, each first magnet includes a common magnet located between two adjacent solenoids and shared by two adjacent driving assemblies. A driving force of the linear vibration motor is significantly improved.
