Abstract:
The present invention provides a vibration motor including a housing with an accommodation space, a vibration member and a fixed member accommodated in the accommodation space, and an elastic support member suspending the vibration member. The elastic support member has an elastic arm, a first fixed part, and a second fixed part. Both the first fixed part and the second fixed part are bent toward the same side of the elastic arm, and the vibration member is located between the first fixed part and the second fixed part. The elastic stress of the elastic support member is effectively improved and the service life of the elastic support member is improved.
