A drum of the present invention comprises: a shell having a plurality of shell members, wherein the upper rim of the shell is provided with a first magnetic component, and wherein the lower rim of the shell is provided with a second magnetic component; a first drumhead provided with a third magnetic component corresponding to the first magnetic component; and a second drumhead provided with a fourth magnetic component corresponding to the second magnetic component. The shell members use a first joining component and a second joining component to be joined with one another so as to form the shell. Furthermore, by magnetism between the first magnetic component and the third magnetic component and magnetism between the second magnetic component and the fourth magnetic component, the first drumhead, the second drumhead and the shell can be joined with one another. A drum of the present invention is advantageous in that it is easy to assemble and disassemble the drum, and accordingly, it is highly convenient whether to carry or to transport the drum.
