Abstract

PURPOSE:To extend the region of linearity of amplitude, by providing the 1st construction section in which the radial length is unchanged and the expansion and compression toward the circumferential direction is compensated and the 2nd construction section compensating in which a folding point is provided radially and the radial length and circumferential expansion and compression can be compensated. CONSTITUTION:One end of a speaker edge 1 is provided with a sticking part 2 to a diaphragm at one end and a sticking part 3 to a frame is provided for another end. When the diaphragm is displaced toward +epsilon, folding points A, B and D move to A', B' and D' respectively by taking a folding point C as a center, the diameter from the center of the diaphragm to the folding point B' is increased and the diameter from the frame to the folding point B' is unchanged. In this case, the circular length of the 1st construction section (a) due to the sum of sides B1', -B2' and B1', -B3' is increased, and an angle <B2B1B3 is increased to compensate the increase in circumference. In the 2nd construction section (b), an angle <A1D1B1 is increaed to be an angle <A1' D1'B1' allowing to compensate the radial length and the elongation toward circumferential direction.
