Abstract
The invention provides a vibration motor includes a housing, a vibrator in the housing, a stator accommodated in the housing, and a number of elastic parts suspending the vibrator in the housing. One of the vibrator and the stator includes a magnetic circuit system, and the other includes a coil. The elastic part is in an H shape, each has a first fixation part fixedly connected with the magnetic circuit system, and two second fixation parts perpendicularly extending from two opposite ends of the first fixation part. In addition, an interval is formed between the two second fixation parts. The second fixation parts and the first fixation part are fixedly connected with the housing. Therefore, the amount of parts of the vibration motor is reduced, the structure of the elastic part is simple, the machining and forming are simplified, and the cost is lower.
