Abstract
The present disclosure provides a speaker diaphragm and a speaker. The diaphragm includes a thermoplastic polyester elastomer film layer, a thermoplastic polyester elastomer being a copolymer composed of a hard segment A of polyester and a soft segment B of polyether or aliphatic polyester, wherein the thermoplastic polyester elastomer film layer has Young's modulus of 1-1000 MPa, with an elastic recovery rate after 10% strain being greater than or equal to 80%. The speaker diaphragm has a good stiffness, a good damping performance and a good resilience.
