[0022] Please refer to image 3 , Which is a cross-sectional view of an embodiment of the ribbon flat speaker of the present invention. The composite sound film 31 of the speaker includes an upper ribbon-type sound film, a planar reinforcing structure 36, and a lower ribbon-type sound film. The upper ribbon sound film is composed of an upper insulating layer 31A and a metal electrode circuit 33A on the upper side of the upper insulating layer. The lower ribbon type sound film is composed of a lower insulating layer 31B and a metal electrode circuit 33B on the lower side of the lower insulating layer. The planar reinforcing structure 36 further has a suspension structure 37.
[0023] Among them, the upper ribbon type sound film and the lower ribbon type sound film are double-layer composite metal films of metal foil / polymer insulation layers 31A, 31B. It first uses a two-layer flexible printed circuit board composed of an aluminum foil layer with a thickness of 23 microns and a pol...
