A method for fabricating a diamond diaphragm is provided, wherein a non-homogeneous energy, generated by a hot wire, plasma, or flame, for activating and dissociating gas is provided to pass above a mold. Due to different distances between a curved surface of the mold and the non-homogeneous energy, different heating effects are produced on the surface of the mold. When the diamond material is coated and grows on the surface of the mold, the growth rate of the diamond material appears to be different by location, thus, the diamond diaphragm has a non-homogeneous vibration characteristic, and thereby having a response bandwidth wider than that of a diamond diaphragm with homogeneous vibration characteristic. |
