Abstract

The present invention provides a vibration motor having a housing with an accommodation space; a vibrator; a stator; and an elastic support assembly suspending the vibrator in the accommodation space. The elastic support assembly includes one elastic support between the vibrator and the housing. The elastic support includes a first fixed part, a second fixed part, a first elastic support arm connecting the first fixed part and the second fixed part, and spaced from the vibrator, and a first flange formed by bending and extending from the first elastic support arm. The first flange keeps a distance from the vibrator or the housing. Such a vibration motor has enhanced stiffness.
