Abstract

PURPOSE:To form a film having a damping effect according to the speaker characteristics, by producing a dissolved optical hardening material to coat it over the edge part of a speaker with an irradiation of light for hardening and at the same time selecting the conditions for irradiation of light. CONSTITUTION:Single-functional oligoester acrylate and acrylic polymer composed essencially of acrylic ester are mixed at the ratio of 100pts. and 20pts. in a flask having a stirrer and stirred until an even solution is obtained. When the mixing completes, 70pts. trisphosphate, 50pts. disebacate and 40pts. trioctyl phosphate are added as a plasticizer plus 3pts. benzoisobutyl ether as a photosensitizer. Then the stirring is continued to obtain a perfectly uniform solution. This mixed solution is coated on a filter paper and then irradiated by the light for two minutes by means of a photomechanical processing device consisting of ten chemical lamps set in parallel. Thus the mixed solution is hardened.
