Abstract

PURPOSE:To enlarge the degree of freedom for tone quality design at the time of design by using a diaphragm whose surface density is varied in the diameter direction so that the dip extending to an intermediate frequency can be controlled easily. CONSTITUTION:To a peripheral edge part of a frame 6, peripheral edge parts of diaphragms 8, 9 are coupled by an adhesive together with a gasket 7. As for the diaphragms 8, 9, the part extending from a neck part leading part 14 to an outside peripheral part 15 is divided equally into three parts in the diameter direction, manufactured with the ratio of 1:2 extending from the leading part 14 to the outer peripheral part 15, sheet making is executed so that its surface density ratio becomes 1:1.5, this sheet making body 16 is formed by a drying press so that the uniform thickness is obtained. Over the whole body, and the diaphragm 8 having low density A and high density B is obtained. Also, by reversing this constitution, sheet making is executed so that the surface density ratio becomes 1.5:1, it is formed by the drying press, and the diaphragm 9 is obtained. In case of eliminating the dip in the vicinity of 2kHz intermediate frequency, the diaphragm 8 is used, and in case of enlarging the drip, the diaphragm 9 is used.
