Abstract
The vibration motor provided by the present disclosure includes an elastic assembly having an elastic frame, a first elastic supporting member, and a second elastic supporting member. The first and second elastic supporting members connects to the housing by the elastic frame. By virtue of the bended structure of the elastic frame, the first and the second elastic supporting members are arranged interlaced along the vibration direction, which greatly reduces the height of the vibration motor.
