Abstract
(EN)
Provided is a vibration electric motor, comprising a housing, a vibrator and a stator accommodated in the housing, and an elastic piece for suspending the vibrator in the housing, wherein one of the vibrator and the stator comprises a magnetic circuit system, and the other one comprises a coil; the elastic piece is in the shape of the Chinese character "工" and comprises a first fixed portion fixedly connected to the magnetic circuit system and two second fixed portions arranged on two opposite ends of the first fixed portion and arranged perpendicular to the first fixed portion, and the two second fixed portions are arranged in parallel at an interval; and the second fixed portions are fixedly connected to the first fixed portion and the housing. According to the vibration electric motor provided by the present utility model, the vibrator is suspended in the housing by the elastic piece having the shape of the Chinese character "工", both the function of fixing the vibrator and a limiting effect can be achieved, and the number of parts of the vibration electric motor is reduced, such that the overall structure of the vibration electric motor is simpler; moreover, the structure of the elastic piece is simple, the processing and forming are simplified, and the cost is lower.
