Abstract

PURPOSE:To enable to finish the coating and curing on the assembling line, by using the mixture of reaction diluent and photoreaction initiator with the acrylic oligomer resin such as diene type, melamine type and vinylpolymer as the damping agent applied to the edge supportion the diaphragm plate. CONSTITUTION:As the damper agent coated on the edge, one of the resin of oligoester-acrylate, epoxyacrylate, and urethaneacrylate is added with the reaction diluent such as acrylic monomer and vinyl monomer, and modifier such as acrylic polymer and photoreaction initiator such as benzil. Thus, coating and curing are made on the speaker unit assembling line, enabling to improve the secondary and tertiary higher harmonic distortion.
