VIBRATION MOTOR

WIPO Patent Application WO/2022/134205

A1

The present utility model relates to a vibration motor, comprising a housing having an accommodating space, a vibration member and a fixed member accommodated in the accommodating space, and an elastic support member suspending and supporting the vibration member in the accommodating space and providing an elastic restoring force for the vibration member. The elastic support member comprises a first fixed portion fixed on the vibration member, an elastic arm having one end connected to the first fixed portion, and a second fixed portion formed by bending the other end of the elastic arm and fixed on the housing; and an extension direction of the first fixed portion is perpendicular to a vibration direction of the vibration member, and an extension direction of the second fixed portion is parallel to the vibration direction. In the vibration motor of the present utility model, by means of configurations of the elastic arm of the elastic support member and a bent structure of the second fixed portion, the accommodating space inside the housing is effectively utilized, a strain area length of the elastic support member is increased, and an elastic stress of the elastic support member is effectively improved, thereby prolonging the service life of the elastic support member, and effectively improving the assembling efficiency and increasing the product utilization rate.
