Abstract: An embodiment of the present invention provides a loudspeaker diaphragm and a loudspeaker. The loudspeaker diaphragm comprises: a center portion, a suspension ring portion, and a fixed portion successively connected from the inside to the outside; the diaphragm is provided thereon with a plurality of patterns that span across the suspension ring portion and the fixed portion; first ends of the patterns extend towards the peripheral edge of the fixed portion, while second ends thereof stretch towards the peripheral edge of the suspension ring portion so as to extend onto the suspension ring portion. The technical solution of the present invention can not only effectively disperse stress of a stress concentration region of the fixed portion, but also can increase the strength of the fixed portion, thus effectively avoiding the problem of warping deformation of the diaphragm after the diaphragm is molded, thereby improving the yield of the diaphragm.
