mold 16 by the linear reciprocating motion of the carriage 11, the point that this was carried out
by the pivoting reciprocating motion is different, but the operation and effect are the same. is
there. Effect of the Invention As described above, since the present invention can form the cone
portion and the edge portion by materials suitable for each, the boundary between the acoustic
cone portion and the edge portion that vibrates faithfully and sensitively to the sound south
signal is a cone. Strong vibration energy because it is joined by the lamination entanglement of
the raw material for the part and the raw material for the age part?
It is possible to obtain corn paper with high input resistance that is not damaged even with Even
when the same raw material is used, corn paper in which the characteristics of the cone portion
and the edge portion are different can be obtained by changing the concentration, the degree of
deagglomeration, and the like for the cone portion and the edge portion. There is a minute gap
between the inner bucket and the die making, and the inner and outer chambers of the die
making table are squeezed alternately, so the material for the cone and the edge are made at the
boundary between the cone and the edge. The raw materials can be stacked to automatically
create a strong bond that entangles. And so on.
