A speaker and the manufacturing method thereof is disclosed wherein a diaphragm is enclosed by the peripheral frame, a resonant space is in the center enclosed by frame and diaphragm, and a winding is around a center seat. Winding is excited to generate varying magnetic lines for generating a continuous attraction-repulsion effect in the magnetic member when an electric current is flowed through, thereby vertically sliding the magnetic member to cause the diaphragm to generate sound. This can significantly reduce the thickness, simplify assembly, reduce manufacturing cost, increase the travel of diaphragm, significantly enhance the low-frequency characteristics, and increase power of speaker.
