[0026] like Figures 1 to 4 As shown, this utility model provides an earphone structure 100 with a composite earphone diaphragm featuring an electromagnetic and suspension design, which includes a mounting shell 10 and a magnet 20, a voice coil 30, and an earphone diaphragm 40 disposed within the mounting shell 10.

[0027] The voice coil 30 is sleeved outside the magnet 20, and the earphone diaphragm 40 comprises a diaphragm body 41, two magnetic conductive rings 42 and an elastic folded ring 43. The two magnetic conductive rings 42 are annular in structure, and are respectively clamped on the upper and lower surface edges of the diaphragm body 41, wherein the lower magnetic conductive ring 42 is arranged on the top surface of the magnet 20. The elastic folded ring 43 is annular in structure, and is arranged outside the diaphragm body 41, and the inner side edge thereof is connected with the upper surface of the upper magnetic conductive ring 42. The outer side edge of the elastic folded ring 43 is arranged along the top side edge of the mounting shell 10, and the middle part of the elastic folded ring 43 is attached to the voice coil 30. The diaphragm body 41 is made of permalloy, and the elastic folded ring 43 is made of flexible polymer material.

[0029] The elastic folded ring 43 comprises an inner folded ring 431 and an outer folded ring 432, and the inner folded ring 431 and the outer folded ring 432 are annular in structure and have an upper arch cross section. The outer side edge of the inner folded ring 431 and the inner side edge of the outer folded ring 432 are integrally connected, wherein the inner side edge of the inner folded ring 431 is higher than the outer side edge of the outer folded ring 432, and the outer side edge of the outer folded ring 432 is higher than the outer side edge of the inner folded ring 431 and the inner side edge of the outer folded ring 432.
