摘要： The present disclosure provides a speaker diaphragm and a speaker. The diaphragm includes two surface layers compounded together and at least one intermediate layer located between the two surface layers, at least one of the surface layers is a thermoplastic polyester elastomer film layer, and at least one of the intermediate layers is an adhesive layer, wherein the thermoplastic polyester elastomer film layer has a Young's module of 1-1000 MPa, a loss factor being greater than or equal to 0.015, and an elastic recovery rate after 10% strain being greater than or equal to 80%. The speaker diaphragm may be made very thin, thus reducing the weight of the speaker diaphragm, improving the space allowance for vibration, improving the sensitivity, and making the F 0 of the speaker lower. Further, elastic area of the speaker diaphragm is wider and the resilience performance is excellent.
