Abstract: A linear vibration actuator motor comprises a housing, a coil, a conductive sheet, a bracket, a magnet assembly and two elastic members. The coil is fixed to the bottom wall of the housing. The conductive sheet is fixed to the top wall of the housing and is located above the coil. The bracket is disposed in an accommodating space of the housing, forming framed space, and located above the coil and below the conductive sheet. The magnet assembly is disposed in the framed space above the coil and directly below the conductive sheet. The two elastic members are respectively located between two ends of the bracket and the inner side of two side walls of the housing. Thereby, the invention utilizes the induced current to provide resistance to achieve the damping effect against the motion of the assembly of the bracket and the magnet set with respect to conductive sheet.
