To provide a speaker diaphragm capable of improving the power linearity while achieving low distortion.SOLUTION: A speaker diaphragm 27 includes: a diaphragm main body 27a arranged in the center; and an edge 27e arranged on the outer periphery of the diaphragm main body 27a. The edge 27e includes: an up roll portion 27b protruding forward; a down roll portion 27c protruding rearward; and a connecting portion 27d connecting the up roll portion 27b and the down roll portion 27c. In the speaker diaphragm 27, the connecting portion 27d has a thinner material thickness than the edges 27e other than the connecting portion 27d.SELECTED DRAWING: Figure 1

    【課題】低歪化を実現しつつ、パワーリニアリティーの向上を実現できるスピーカ用振動板を提供すること。【解決手段】中心に配置される振動板本体27aと、振動板本体27aの外周に配置されるエッジ27eと、を備えるスピーカ用振動板27であって、エッジ27eは、前側に向かって突出するアップロール部27bと、後側に向かって突出するダウンロール部27cと、アップロール部27bとダウンロール部27cとを連結する連結部27dと、を備え、連結部27dは、連結部27d以外の他のエッジ27eよりも材厚が薄いスピーカ用振動板27。【選択図】図1
