The present invention provides a coil and a speaker module. The coil of the present invention includes N layers of winding layers wound around a first axis from the inside to the outside, where N is an integer greater than 1, and the adjacent winding layers are connected by winding switching sections. The winding switching sections along the projection on a plane perpendicular to the first axis do not overlap with each other, thereby avoiding a concentrated arrangement in the thickness direction of the coil, reducing the overall thickness of the coil, reducing the magnetic gap, and improving the conversion efficiency and sensitivity of the speaker components used in the speaker module.
