Abstract: The present application provides a loudspeaker diaphragm, comprising a first surface layer, a middle layer and a second surface layer, that are in a stacked structure. The loudspeaker diaphragm is characterized in that: at least one surface layer of the first surface layer and the second surface layer has a composite structure which is composed of a base layer and a reinforcing layer, and the other surface layer comprises a base layer; the base layer is a poly(ether-ether-ketone) layer, a polyarylester layer, a polyethylene terephthalate layer, a polyetherimide layer or a composite structure composed of any two of the above layers, and the reinforcing layer is a thermoplastic polyurethane elastomer layer or a thermoplastic elastomer layer. The loudspeaker diaphragm can reduce diaphragm breakage after power test is performed on a loudspeaker product, improve substrate toughness and improve acoustical property of the loudspeaker.

Abstract: The present invention discloses a vibration system of a loudspeaker, comprising a diaphragm and a voice coil attached to one side of the diaphragm, wherein the diaphragm comprises at least two layers of polyether-ether-ketone base films, and furthermore, the diaphragm comprises at least one layer of crystallized polyether-ether-ketone base film and at least one layer of non-crystallized polyether-ether-ketone base film. The diaphragm made of both crystallized and non-crystallized polyether-ether-ketone base films can have both an effectively improved acoustic performance and a lowered resonance frequency f0, thus, the acoustic effect of the loudspeaker can be improved
