▎ 摘　　要

NOVELTY - The diaphragm has an insulating film (1) provided with a magnetic pole corresponding area (4). Each of conductive films (2) is connected to one of the insulating films, multiple conductive films are arranged at intervals, and two sides of each of the conductive films are respectively provided with the magnetic pole corresponding areas. Multiple conductive films are connected in series by multiple communicating elements (3) to form a power-on circuit. The insulating film comprises first surface and second surface arranged opposite to each other, and multiple conductive films are all connected to the first surface. Multiple conductive films comprise multiple first sub-films and multiple second sub-films. USE - Vibrating diaphragm for sounding unit of audio device (all claimed). ADVANTAGE - The insulating film is connected to multiple conductive films arranged at intervals, and the magnetic pole corresponding areas are respectively arranged on two sides of each conductive film, such that a conductive film having a relatively large area is located in a relatively strong magnetic field, each conductive film also emits low-frequency sound meeting user needs, and the conductive film can cover a treble/tenor/bass spectrum. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a sounding unit of audio device; and an audio device with vibrating diaphragm. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a three-dimensional structure of a vibrating diaphragm. 1Insulating film 2Conductive film 3Communicating element 4Magnetic pole corresponding area
