Abstract
The production equipment of paper-made components for loudspeakers includes a mixing device, a fining device, a paper-making device, and a shape processing device. The mixing device mixes material of a paper-made component for a loudspeaker into liquid to generate mixed liquid. The fining device includes a pressure unit, an orifice, and an inner wall. The pressure unit applies pressure on the mixed liquid to cause the mixed liquid to pass through the orifice, and the mixed liquid collides against the inner wall to cause the fining device to generate fined material. The paper-making device paper-makes the fined material to generate a paper-made component. The shape processing device processes the shape of the paper-made component. This structure provides production equipment of the paper-made components for loudspeakers, which prepares material for paper-making in a short time and reduces producing time.
