Abstract:
One of the objects of the present invention is to provide a linear vibration motor which improves damping performance and reduces assembly costs. Accordingly, the present invention provides a linear vibration motor having a housing body with an inner cavity; a weight accommodated in the housing body; a stator located in the housing body; and an elastic member suspending the weight in the housing body. The elastic member includes a first elastic member having a first fixed part fixedly connected to one side of the weight and a first elastic bracket extending from the first fixed part, and a second elastic member fixedly connected to an opposite side of the weight a first damping glue locating between the first elastic member and the weight, and locating at one end of the first elastic bracket close to the first fixed part.
