PURPOSE:To obtain the speaker edge which has the proof strength to moisture and heat, maintains proper stiffness and has large vibration absorbing power. CONSTITUTION:This edge is constituted of the three-layered structure formed by using a woven fabric of polymethaphenylene isophthal amide fibers as a base material (1) and coating the front surface and weaving mesh holes thereof with a resin material (2) for vibration absorption and further a resin (3) for restraining having the higher hardness, respectively. |
