Abstract: A diaphragm and a sound generating apparatus. The diaphragm comprises at least one elastomer layer, and the elastomer layer is made of a rubber compound. The rubber compound comprises nitrile rubber and hydrogenated nitrile rubber. Both the nitrile rubber and the hydrogenated nitrile rubber contain acrylonitrile blocks. In terms of mass percentage, the range of the content of acrylonitrile blocks is 20% to 80%. The described diaphragm has excellent mechanical strength, cold resistance, and resilience, and has high damping performance.
