<p>PROBLEM TO BE SOLVED: To make cheering at the time of sports observation louder as a megaphone and to generate a cheering sound by hitting split cylinder bodies against each other other like wooden clappers, by providing a coupling means for the belly parts of split barrel parts, which are completely divided along the barrel axis. SOLUTION: In the state where a circulaly sectioned megaphone is split in two along the barrel axis, split cylinder bodies 2 consisting of an expanded barrel part 2a and a contracted opening part 2b are formed. Then, the megaphone 1 is constituted by coupling the split barrel parts 2 by using the coupling means 4 provided opposite the belly part 3a which corresponds to the contracted opening part 2b between the opposite belly parts 3 of the split cylinder bodies 2 so that they can be separated at the contracted opening part 2b. The split cylinder bodies 2 are formed by bending the barrels away from the center to the axis of the megaphone at the enlarged barrel parts 2 and a V-shaped opening gap is formed by bending in the decentralizing direction at the belly parts 3 of the enlarged barrel parts 2a of the coupled megaphone.</p> |
