Abstract: A linear vibration motor, comprising a stator assembly and a vibrator assembly. The stator assembly comprises a housing (1) having a receiving cavity, a magnet (2) located in the receiving cavity and jointly fixed to the housing (1), and a central magnetic yoke (3) of which at least one end is jointly fixed to the housing (1). The magnet (2) comprises a hollow portion (21) extending along the vibration direction of the vibrator assembly. The vibrator assembly comprises a coil (4) and a mass block (9). When the vibrator assembly vibrates, the coil (4) vibrates along with the vibrator assembly and is inserted into the hollow portion (21) of the magnet (2). The central magnetic yoke (3) runs through the coil (4). An resilient support member (5) is configured to suspend the vibrator assembly in the receiving cavity of the housing (1). According to the linear vibration motor, the magnetism of the magnet can be utilized to the greatest extent, thereby improving the efficiency of utilizing the magnetic line of force of the magnet by the coil, the central magnetic yoke functions as a guide shaft, thereby ensuring the vibration coaxiality of the vibrator assembly.
