Abstract
An edge for loudspeaker diaphragm is made by disposing a diaphragm one of a pair of mating molds, disposing a strip-shaped base material of the edge on the said one of the molds, and hot-molding them with the other mold mated with the one mold. Foaming action of the base material occurs, and an eventual foamed edge is integralized with the diaphragm.
