Abstract
A linear vibration motor comprising a housing, a stator, an vibrator, and two sets of elastic support assemblies which are located at two ends of the vibrator, respectively, and used for supporting the vibrator and providing elastic restoring forces, wherein each set of the elastic support assemblies comprises at least two elastic supports. Each elastic support comprises a first connection point coupled to the vibrator and a second connecting point coupled to the housing. both the first connection point and the second connection point which are located on the same elastic support are located on the same side of a central axis of the vibrator, and the central axis is parallel to a vibration direction of the vibrator; and the second connection point is coupled onto a side wall, perpendicular to the vibration direction of the vibrator, of the housing. The linear vibration motor of the present invention has a simple structure, is low in assembly difficulty and high in production efficiency.
