Abstract
A micro-speaker includes a frame and a drum paper including a diaphragm and a surround. The diaphragm is flexibly connected to one end of the frame via the surround, thereby forming a first suspension system. A magnetic structure includes a main magnetic portion and a yoke covering and surrounding the main magnetic portion. A magnetic gap is provided between the main magnetic portion and a folded portion of the yoke. A voice coil is sleeved on an outer periphery of the main magnetic portion and penetrates into the magnetic gap. One end of the voice coil is fixedly connected to the diaphragm. A one-piece elastic member is flexibly connected to a first surface of a bottom of the yoke and a bottom surface of the frame, thereby forming a second suspension system.
