Abstract
A vibration motor includes a housing; a vibration module including a main magnet and a central shaft extending along a vibration direction and passing through a center of the main magnet; a fixing module located in the housing and including a first coil and a second coil spaced from the main magnet; an elastic connecting part suspending the vibration module in the housing; and a sensor for detecting a displacement of the vibration module along a direction perpendicular to the central shaft. The first coil and the second coil are such arranged that a geometric center of one of the first coil and the second coil deviates from the central shaft, a geometric center of the other of the first coil and the second coil deviates from the central shaft, and the two geometric centers locate at two opposed sides of the central shaft.
