Voice coil motor for swinging

The utility model discloses a voice coil motor for swinging. The voice coil motor comprises a casing, a rotor and a stator. The machine shell is cylindrical, the stator is fixedly arranged in the machine shell, the rotor is provided with a winding groove used for winding a coil and further provided with a groove used for being matched with the stator, the stator can be arranged in the groove, and the end face of the end, away from the stator, of the circular truncated cone is the end face of the rotor. And the diameter of the end face of the circular truncated cone far away from the stator is smaller than that of the end face close to the stator. The rotor has the advantages that one end of the rotor is the circular truncated cone, so that the side surface of the rotor is a conical surface, and the rotor can swing conveniently. 本实用新型公开了一种摆动用音圈电机，包括机壳、动子和定子。所述机壳呈筒状，所述定子固定设机壳内，所述动子设置有用于缠绕线圈的绕线槽，还设置有用于与定子配合的凹槽，所述定子可置于凹槽内，所述圆台远离定子一端的端面为动子的端面，且圆台远离定子一端的端面的直径小于靠近定子一侧的端面。优点：将动子的一端设置为圆台，可以使得动子侧面为锥面，便于动子能够进行摆动运动。
