However, the present invention is not limited thereto, and the main body 11 may be formed in various shapes such as a cylindrical shape. The main body 11 can be manufactured in proportion to the size of the battery unit 20 and the speaker unit 40 so as to minimize the size.

On the other hand, the battery unit 20 and the speaker unit 40 are housed in the hollow portion of the main body 11. Here, the main body 11 includes a partition plate 14 forming a space for accommodating the battery unit 20 and the speaker unit 40, respectively.

The partition plate 14 can divide the hollow portion of the main body 11 into two regions according to the size of the battery portion 20 and the speaker portion 40 in the form of a plate parallel to the bottom surface of the main body 11. [ The speaker unit 40 can be housed in the lower portion of the partition plate 14, and the battery unit 20 can be housed in the upper portion. Here, the positions of the speaker unit 40 and the battery unit 20 may be changed. The partition plate 14 is formed to be horizontal with respect to the bottom surface and the partition plate 14 is formed perpendicular to the bottom surface so that the battery unit 20 or the speaker unit 40 can be accommodated As shown in FIG.

On the other hand, the first lid 12 can be fixed while enclosing one side of the main body 11 which is open on both sides. The first lid 12 can be fixed by screwing a fixing member to a protrusion 11a formed on one side of the main body 11.
