Claim 0:
1. A conductive film for a sound generation device, wherein the conductive film comprises a conductive layer and base material layers provided at two sides of the conductive layer,
wherein the conductive film comprises an inner side portion at an inner side of the conductive film, a curve-shaped deformation portion outside the inner side portion and an outer side portion outside the deformation portion,
wherein the conductive layer comprises a first conductive layer provided on the inner side portion, a second conductive layer provided on the deformation portion and a third conductive layer provided on the outer side portion, two ends of the second conductive layer are respectively electrically connected to the first conductive layer and the third conductive layer, and the first conductive layer, the second conductive layer and the third conductive layer are connected to form at least one conductive path, and
wherein each of the first conductive layer and the third conductive layer is made of a metal sheet, and Young's modulus of the second conductive layer is smaller than Young's modulus of the metal sheet.
