A earphone, includes a shell and the pronunciation subassembly configured in the shell, the shell includes a front side shell and an interdependent rear side shell, the pronunciation subassembly includes a flute profile bracket , the vibrating diaphragm whose periphery fixed to the flute profile bracket , the voice coil connected to the vibrating diaphragm, the magnetite configured in the slot base of the bracket and two connecting wires whose one end connects the voice coil and the other end connects a exterior tone source, the voice coil bushes the magnet, the vibrating membrane, voice coil and magnet are coaxial, the vibrating membrane is adjacent to the rear side of the shell, the magnet is close to the front side of the shell. The earphone of the present invention can not generate positive pressure to a brain because the earphone diaphragm is configured close to the rear side of the shell, the eardrum suffers negative pressure, in the meanwhile, the eardrum and the vibrating diaphragm are same in the vibration direction and vibrate synchronistically, so can not disturb the vibrating diaphragm.
