Abstract:
The present disclosure discloses a conductive film for a sound generation device and the sound generation device, the conductive film comprises a conductive layer and base material layers provided at two sides thereof, conductive layer comprises a first conductive layer on an inner side portion, a second conductive layer on a deformation portion and a third conductive layer on an outer side portion, two ends of the second conductive layer are respectively electrically connected to the first and third conductive layers, the first, second and third conductive layers are connected to form at least one conductive path, each of the first and third conductive layers is made of a metal sheet, Young's modulus of the second conductive layer is smaller than the metal sheet. The conductive film has conductivity, it can be used as a sound generation diaphragm and a supporting diaphragm.
