Abstract: An elastic spheroid structure includes a hollow elastic spheroid body having an elastic spheroid shell, a receiving space formed inside the elastic spheroid shell, and a through opening passing through the elastic spheroid shell and being in air communication with the receiving space. The through opening has a first predetermined shape, the through opening has a first middle portion and a plurality of first extending portions extended outwardly from the first middle portion, and the first predetermined shape of the through opening is formed by connecting the first middle portion and the first extending portions. The elastic spheroid structure further includes a solid elastic cover body disposed inside the through opening of the hollow elastic spheroid body and a connection layer disposed inside the through opening and connected between the elastic spheroid shell and the solid elastic cover body.
