a breaking part formed between the base body and the clasp.

5. The display apparatus according to claim 1 , wherein a distance between the rear surface of the display panel and the inner side of the middle frame corresponds to a height of the sound generating device.

6. The display apparatus according to claim 5 , wherein the latch holder is disposed as being apart from the latch, when the position adjustment element is disposed as being apart from the height adjustment element, and

wherein the latch holder is engaged with the latch and the sound generating device is fixed to the middle frame, when the display panel is moved to settle the position adjustment element at a correct position on the height adjustment element.

7. The display apparatus according to claim 6 , wherein the display panel and the sound generating device are disassembled from the middle frame as breaking the latch, when separating the display panel from the middle frame in a vertical direction.

8. The display apparatus according to claim 5 , wherein the sound generating device includes a guide protrusion disposed around the latch holder, and

wherein the latch further includes a rail member receiving the guide protrusion, the guide protrusion moving within the rail member.

9. The display apparatus according to claim 8 , wherein the latch holder is disposed as being apart from the latch, and the guide protrusion is inserted into one end of the rail member, when the position adjustment element is disposed as being apart from the height adjustment element, and

wherein the latch holder is engaged with the latch and the sound generating device is fixed to the middle frame, and the guide protrusion is moved to another end of the rail member, when the display panel is moved to settle the position adjustment element at a correct position on the height adjustment element.

10. The display apparatus according to claim 9 , wherein the display panel and the sound generating device are disassembled from the middle frame as breaking the latch, when separating the display panel from the middle frame in a vertical direction.

11. The display apparatus according to claim 1 , wherein the position adjustment element includes:

an attaching surface fixed to the display panel;

a position adjusting surface protruded from the attaching surface toward the height adjustment element;

a position limiting hole disposed at the position adjusting surface; and

an adjusting chamber disposed between the attaching surface and the position adjusting surface,

wherein the position limiter includes:

a head mounted in the adjusting chamber;

an extrusion protruded from a center portion of a bottom surface of the head; and

a cushion attached on an upper surface of the head,

wherein the position limiting hole has a diameter that is smaller than the head and larger than the extrusion, and

wherein the extrusion is configured to penetrate the position limiting hole and to be inserted into the base hole.

12. The display apparatus according to claim 11 , wherein the position adjusting hole includes an oval shape having a major axis and a minor axis,

wherein the minor axis has a minor length that is the same as a diameter of the extrusion, and

wherein the major axis has a major length larger than the diameter of the extrusion, and is disposed at a diagonal direction on a surface of the display panel.

13. The display apparatus according to claim 12 , wherein the latch holder is disposed as being apart from the latch, when the extrusion is inserted into the base hole, and the position limiting hole is located at one end with respect to the extrusion, and

wherein the latch holder is engaged with the latch and the sound generating device is fixed to the middle frame, when the position limiting hole is moved to another end with respect to the extrusion to settle the position adjustment element at a correct position on the height adjustment element.

14. The display apparatus according to claim 13 , wherein the display panel and the sound generating device are disassembled from the middle frame as breaking the latch, when separating the display panel from the middle frame in a vertical direction.

15. The display apparatus according to claim 1 , further comprising:

an adhesive layer disposed between an upper surface of the sound generating device and the rear surface of the display panel to attach the sound generating device to the display panel.
