Loudspeaker diaphragm
First Claim
1. A loudspeaker diaphragm, comprising a first surface layer, an intermediate layer and a second surface layer in a lamination structure, whereinat least one surface layer of the first surface layer and the second surface layer is a composite layer composed of a base layer and a reinforcing layer, and the other surface layer comprises at least a base layer, andthe base layer is any one selected from a group consisting of a polyetheretherketone layer, a polyarylester layer, a polyethylene terephthalate layer and a polyetherimide layer, or a composite layer composed of any two selected from the group;
- the reinforcing layer is a thermoplastic polyurethane elastomer layer or a thermoplastic elastomer layer.

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.
