wherein the first short surface and the second short surface of the magnet are covered by the casing with the first long surface and the second long surface of the magnet being externally exposed from the speaker assembly at the outside of the casing, and

wherein a distance between the first long surface and the second long surface of the magnet is substantially identical to a thickness of the casing.

2. The electronic device of claim 1 , wherein the magnet further includes a lower surface opposite the upper surface, and

wherein the speaker unit further includes a frame disposed on the lower surface of the magnet.

3. The electronic device of claim 2 , wherein the frame is disposed along a center axis of the casing.

4. The electronic device of claim 3 , wherein the frame is disposed offset from a center axis of the casing.

5. The electronic device of claim 3 , wherein the speaker unit, the frame, and the magnet form a single unit that is attachable and detachable from the casing.

6. The electronic device of claim 1 , wherein the casing comprises an outer side including a first outer side, a second outer side connected with the first outer side, and a third outer side connected with the second outer side,

wherein the first outer side faces the third outer side,

wherein the first outer side faces one of the first short surface and the second short surface of the magnet, and the third outer side faces the other one of the first short surface and the second short surface of the magnet, and

wherein the second outer side faces the upper surface of the magnet.

7. The electronic device of claim 6 , wherein the outer side of the casing corresponds to a shape of the magnet to accommodate the magnet.

8. The electronic device of claim 6 , wherein the casing includes an opening adjacent to the first outer side, the second outer side and the third outer side, the speaker unit communicates with the internal space of the casing through the opening.

9. The electronic device of claim 8 , wherein the casing further includes an inlet hole in the internal space and an outlet hole in communication with the inlet hole through a path.

10. The electronic device of claim 9 , wherein the outlet hole faces toward an outside of the casing in order to spread sound from the speaker unit toward the outside of the casing.

11. The electronic device of claim 9 , wherein the casing further comprises at least one wall within the internal space of the casing and the at least one wall forms the path where the inlet hole of the casing communicates with the outlet hole of the casing.

12. The electronic device of claim 1 , wherein the casing is formed by combining a first casing part with a second casing part.

13. The electronic device of claim 1 , wherein the speaker assembly is downwardly placed at the bottom of the body of the electronic device.

14. The electronic device of claim 1 , wherein the speaker assembly further comprises a cushion, wherein the cushion is disposed at an outer surface of the casing of the speaker assembly.

15. The electronic device of claim 14 , wherein the speaker assembly abuts two inner surfaces of the body of the electronic device with the cushion there between.

16. The electronic device of claim 1 , wherein the upper surface of the magnet is covered by the casing with the first long surface and the second long surface of the magnet being externally exposed from the speaker assembly at the outside of the casing.

17. The electronic device comprising:

a body;

a display in front of the body; and

a speaker assembly inside the body,

the speaker assembly comprises:

a casing to form an external appearance and having an internal space including a resonant region, a speaker unit mounted on the casing,

wherein the speaker unit comprises a magnet including a first long surface, a second long surface opposite the first long surface, a first short surface between the first long surface and the second long surface, a second short surface opposite the first short surface, an upper surface connected with the first long surface, the second long surface, the first short surface, and the second short surface,

wherein the first short surface, the second short surface, and the upper surface of the magnet are covered by the casing with the first long surface and the second long surface of the magnet being externally exposed from the speaker assembly at the outside of the casing, and

wherein an outer side of the casing corresponds to a shape of the magnet to accommodate the magnet.

18. The electronic device of claim 17 , wherein the magnet further includes a lower surface opposite the upper surface, and

wherein the speaker unit further includes a frame disposed on the lower surface of the magnet.

19. The electronic device of claim 18 , wherein the casing includes an opening adjacent to the first outer side, the second outer side and the third outer side, the speaker unit communicates with the internal space of the casing through the opening.

20. The electronic device of claim 19 , wherein the casing further includes an inlet hole in the internal space and an outlet hole in communication with the inlet hole through a path.

21. The electronic device of claim 20 , wherein the outlet hole faces toward an outside of the casing in order to spread sound from the speaker unit toward the outside of the casing.

22. The electronic device of claim 20 wherein the casing further comprises at least one wall within the internal space of the casing and the at least one wall forms the path where the inlet hole of the casing communicates with the outlet hole of the casing.

23. The electronic device of claim 17 , wherein the outer side includes a first outer side, a second outer side connected with the first outer side, and a third outer side connected with the second outer side,

wherein the first outer side faces the third outer side,

wherein the first outer side faces one of the first short surface and the second short surface of the magnet, and the third outer side faces the other one of the first short surface and the second short surface of the magnet, and
