Linear vibration motor

Abstract

A linear vibration motor, including a housing having a receiving space; a vibration assembly and a stator assembly that are received in the receiving space; and an elastic member supporting the vibration assembly in the receiving space. The vibration assembly includes a weight suspended in the receiving space, and the weight has a receiving hole penetrating through the weight. The vibration assembly further includes an iron core fixed to the weight and received in the receiving hole, and a coil wound around the iron core; and the stator assembly includes a magnet fixed to the housing, and the magnet extends into the receiving hole and is spaced from the coil and the weight. The linear vibration motor has an improved electromagnetic field utilization rate of the iron core and the coil and enhanced magnetic field intensity of the magnet, and an improved driving force and vibration performance.
