Abstract
The present disclosure discloses an earphone core having a frame with a receiving space and a magnet unit and a vibration unit both fixed on the frame. The magnet unit includes a yoke and the first magnet. The vibration unit includes a diaphragm and a coil fixed on the diaphragm; a MEMS tweeter for providing high frequency sound is mounted on the first magnet the MEMS tweeter, the coil and the diaphragm are coaxially arranged along a vibration direction of the diaphragm. An axial height of the earphone core is effectively reduced, thereby saving its occupied space when applied in TWS earphone products.
