PURPOSE: To accommodate the titled ear speaker into a small space and to attain simple removal, by providing a side groove on which a jumper is wound to the side of a containing box and forming a plug so that it is pushed in a retain groove, retaind, pressed and nipped out.
CONSTITUTION: The containing box 1 is provided with an ear speaker main body containing sections 2a, 2b and the side groove 4 on which the jumper 13 of ear speaker main bodies 11a, 11b is wound at the center. First, the main bodies 11a, 11b are contained in the containing sections 2a, 2b, the jumper 13 is wound on the side groove 14, the plug 14 is pushed in the plug retain groove 5 provided at the side groove 4 and retained. In this case, the interval between opposite side walls and the groove is taken slightly narrower than that of the outermost diameter of the plug 14. In removing the plug 14 from the retained state, when a finger depresses a plug end 14a from a notch 9 provided at the lower wall, the tip of the other part of the plug 14b is projected by taking the outermost diameter 14c of the plug 14 as a fulcrum. Thus, the tip 14b of the plug 14 is nipped out.
