Abstract

PURPOSE:To reduce the weight of the diaphragm of a dynamic converter for open air type headphones in particular, change the modulus of elasticity of the dome and edge parts and improve performances by changing the degree of crystallinity of the dome and edge parts using a thin crystalline high polymer film.
