Abstract

본 발명은 천연 고분자 물질인 키토산(chito acid)에 고탄성 단섬유를 강화재로 혼합한 것을 제조 원료로 사용하는 스피커용 진동판 및 그 제조 방법에 관한 것으로서, 천연 고분자 물질인 키토산에 강화재인 카본 화이바 또는 아라미드 등의 고탄성 단섬유를 혼합하여, 키토산 자체가 지닌 고 내부손실율을 유지하면서 결합력 및 탄성율을 보다 향상시킨 복합 키토산 재로로 진동판을 제조함으로서 우수한 음질을 출력하는 스피커를 얻을 수 있는 효과가 있다.The present invention relates to a diaphragm for loudspeaker using chitosan as a raw material for producing a mixture of chitosan and high-elasticity staple fiber as a raw material, and to a method for preparing the diaphragm for loudspeaker. The present invention provides a speaker capable of producing a speaker with excellent sound quality by manufacturing a diaphragm made of a composite chitosan material having improved bonding strength and elasticity while maintaining a high internal loss ratio of chitosan itself.
