发明名称	CONE PAPER FOR SPEAKER
摘要	PURPOSE: A Hanji cone paper for a speaker is provided to completely reproduce original sounds by making a material of a cone paper for a speaker with a Korean paper of paper mulberry fabric. CONSTITUTION: A cone paper(10) for a speaker is made of a paper mulberry fiber. The cone paper has a funnel shape. The cone paper has a top portion widely opened and a lower portion having a narrow width. A process for manufacturing the cone paper includes a paper mulberry fiber extracting process, a paper mulberry fiber beating process, a paper mulberry fiber stirring process, a formation process of forming a paper mulberry fiber into a cone paper shape. The process for manufacturing the cone paper includes a dehydration process of eliminating moisture from the paper mulberry fiber, a shaping process of heating and pressing the paper mulberry fiber of a cone paper shape at high temperatures, and an ejection process of taking out the cone paper to the outside.
