Manufacturing method of paper making part for loudspeaker, paper making part for loudspeaker, diaphragm for loudspeaker, sub cone for loudspeaker, dust cap for loudspeaker and loudspeaker
A manufacturing method of a paper making part for a loudspeaker has freedom of adjusting a characteristic and a sound quality, and has a higher productivity. Accordingly, a fibrillating step of a paper making material is achieved by an explosive crushing step. Alternatively, the step is achieved by a mixing step of a paper making material and a liquid, a material micro-fabricating step of applying a pressure to a mixed solution obtained by the mixing step so as to pass through an orifice and thereafter run into a device wall, and a paper making step including the micro-fabricated material.
