A vibration diaphragm, especially a vibration diaphragm used for a loudspeaker, is disclosed in the present invention. The vibration diaphragm includes: a hollow, truncatedly conical diaphragm body with a first end, a second end, a front surface and a rear surface, wherein the front surface and the rear surface are arranged between the first end and the second end, and the inner diameter of the first end is larger than the inner diameter of the second end; an elastic annular edge having an annular shape matched with the first end of the diaphragm body, and connected with the first end of the diaphragm body; and at least three balancing patches in the shape of a sheet, the patches being all fixed on the front surface and/or the rear surface of the diaphragm body. The balancing patches are attached to the front surface of the diaphragm body, and arranged at equal intervals along the circumferential direction of the diaphragm body. The object of the present invention is to provide a vibration diaphragm capable of reducing distortion effectively. |
