Abstract

PURPOSE:To remove the edge resonance of a loudspeaker, and to obtain a satisfactory frequency characteristic, by adding a foaming agent to thermoplastic elastomer, foaming it by continuously executing crosslinking reaction, and increasing an internal loss. CONSTITUTION:A foaming agent is added to polybutadience, and is foamed at the same time, continuously executing crosslinking reaction for coupling between the molecules as a bridge. Subsequently, an edge for a loudspeaker is formed by means of vacuum forming, air pressure forming, heat compressing, etc. In this way, since an internal loss of an edge for a loudspeaker is increased, the edge resonance is removed, and a flat sound pressure frequency characteristic is obtained.
