An electronic apparatus is disclosed. The electronic apparatus includes an electronic device, a supporting base, at least a fixing member and at least a protrusion structure. The electronic device has at least a first fixing hole. The supporting base has at least one supporting rod, wherein the supporting rod has at least a second fixing hole. The fixing member is inserted through the first fixing hole and the second fixing hole. The protrusion structure is positioned on the supporting rod and is positioned between the electronic device and the supporting rod such that the center of gravity of the electronic device is shifted to substantially coincide with that of the supporting base to steadily position the electronic device on the supporting base.
