Abstract: A diaphragm structure is used for an audio signal output device. The diaphragm structure includes a film substrate, a polymer fiber structure and a thin film metallic glass. The film substrate includes a first surface and a second surface opposite to the first surface. The polymer fiber structure is combined with the first surface of the film substrate. The thin film metallic glass is formed on at least a part of the second surface of the film substrate.
