Speaker Damper Substrate

Abstract

A speaker damper substrate is to be made from several types of yarns for fabrication. The yarns include a general-grade fiber and a lower-melting fiber, whose melting point is lower than the general-grade fiber. In addition, the proportion ratio of the general-grade fiber and the lower-melting fiber is in the range of 95˜5%:5˜100%. The surrounding region of the overlapping area of the yarns is bonded using the lower-melting fibers due to their melting behavior for improving the mechanical properties of the substrate. In addition, the substrate can perform the resin-immersion process to further improve its rigidity and the compression molding effectiveness.
