Abstract
A vibration motor is provided in the present disclosure. The vibration motor includes a shell providing an accommodating space, a vibrating system accommodated in the accommodating space, a pair of elastic connectors for suspending the vibrating system in the accommodating space, and at least one block member fixed to the shell. The vibrating system includes at least one mass member with a limiting groove, the limiting groove is formed at a surface of the at least one mass member along a direction perpendicular to a vibrating direction of the vibrating system. The at least one block member is partly received in the limiting groove, and a distance between the at least one block member and the at least one mass member is not greater than a maximum vibrating amplitude of the vibrating system.
