A vibration electric motor, comprising a housing (100), and a vibrator (200) and a stator (300), which are accommodated in the housing (100), wherein one of the vibrator (200) and the stator (300) comprises a solenoid structure (310), and the other one of the vibrator (200) and the stator (300) comprises a magnetic circuit structure (210); the solenoid structure (310) comprises an iron core (311), a coil (312) wound around the iron core (311), and pole shoes (313) fixed at two ends of the iron core (311); and the iron core (311) comprises a body (3111) and several magnetic conductive sheets (3112) stacked opposite the body (3111), and the magnetic conductive performance of at least one magnetic conductive sheet (3112) is stronger than that of the body (3111). The solenoid structure (310) or the magnetic circuit structure (210) is driven to vibrate by means of interaction between the solenoid structure (310) and the magnetic circuit structure (210), so as to realize the vibration of the vibration electric motor. The iron core (311) comprises the body (3111) and the several magnetic conductive sheets (3112) stacked opposite the body (3111), and the magnetic conductive performance of at least one magnetic conductive sheet (3112) is stronger than that of the body (3111), such that it is more difficult for the iron core (311) to reach magnetic saturation, and thus, the driving force applied to the vibrator (200) does not decrease when the vibrator vibrates to the maximum amplitude, thereby improving the performance of the vibration electric motor.
