When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, an embodiment of the present application provides a voice coil motor for swing, including a housing 1, a mover 2, and a stator 3. Casing 1 is the tube-shape, stator 3 is fixed establishes in casing 1, be provided with the wire winding groove 21 that is used for the winding coil on the active cell 2, still be provided with be used for with stator 3 complex recess 22, in recess 22 can be arranged in to stator 3, active cell 2 keeps away from 3 one end of stator and is provided with round platform 23. The end face of the circular truncated cone 23, which is far away from one end of the stator 3, is the end face of the mover 2, and the diameter of the end face of the circular truncated cone 23, which is far away from one end of the stator 3, is smaller than that of the end face close to one side of the stator 3.
