Abstract

PURPOSE:To obtain an excellent reproduced signal free from mechanical strain even in a low frequency range by empolying diamond pattern structure for a roll-shaped edge and by making the circumferential expansion and contraction of the edge due to the displacement of a cone correspond to the displacement of the cone. CONSTITUTION:To form edge 12 of a material such as paper, a combination of small triangles of diamond pattern structure is formed annularly and provided at the outer circumference of cone 6. As X1-directional force is applied, edge 12 changes in shape decreasing the angle of the intersection of two planes determined by triangles adjoining mutually in parallel to the edge to contract in direction y1. On the other hand, as X2-directional force is applied to bend the edge, the angle of the intersection of two planes determined by triangles adjoining mutually in parallel to the edge increases to expand the edge in direction y2. consequently, when the displacement of cone 6 is large, a reproduced signal free from mechanical strain is obtained from a low-frequency sound signal close to low frequency resonance frequency f0.
