Abstract
The present disclosure provides a vibration motor, including a housing with an accommodation space; a vibration part and a stator contained in the accommodation space; an elastic support suspending and supporting the vibration part in the accommodation space for providing elastic restoring force to the vibration part. The elastic support includes a first fixed part fixed on the vibration part, an elastic arm with one end thereof connected to the first fixed part, and a second fixed part formed by bending another end of the elastic arm and fixed on the housing. An extension direction of the first fixed part is perpendicular to a vibration direction of the vibration part, and an extension direction of the second fixed part is parallel to the vibration direction. Thus, the service life of the elastic support is improved.
