Abstract
The article relating to this design is formed by assembling a single resin plate into a cylindrical shape and is used as a megaphone. Furthermore, as shown in the reference unfolded diagram, the article relating to this design is fan-shaped when unfolded, and linear bends (dashed lines) are folded radially from the center of the arc of the fan shape at regular angles, forming an accordion-like shape and rolling it into a cylinder, and inserting pieces are inserted into notches, so that when viewed from the front, it is assembled into a star-shaped cylinder.
