<p>Provided is an improved simple bobbin case for rearranging an earphone cord thereon. Upper and lower circular cover plates are made of metal, respectively, to thereby heighten elasticity when the shape of each metallic circular cover plate is changed from a convex surface (H) into a concave surface (U). A protrusion is respectively formed on the upper and lower portions of a buffering bobbin, to thereby play a role of a lever over shape deformation of the metallic upper and lower plates. Upper and lower fixing hooks are made circular, to thus make rearrangement of earphone cord easier than that of the conventional simple earphone cord rearrangement bobbin case. The earphone cord rearrangement bobbin case can operate even at a closed state, to thus heighten convenience in use.</p> |
