Abstract

PURPOSE:To surely transmit the vibration of a voice coil from a cone neck part to the peripheral part of the cone by making the board thickness of the cone neck part thicker that of the peripheral part, and making almost all the fibers stretch from the cone neck part to the peripheral part. CONSTITUTION:A speaker diaphragm, 7 is constituted of highly elastic or strong fiber and a thermosetting or thermoplastic resin. Almost all the fibers in the radial direction of the diaphragm 7 are stretched from the cone neck 7a to the cone peripheral part 7b. The board thickness of the cone neck part 7a is thicker than that of the part 7b, and the strength of the part 7a is made strong.
