Speaker assembly and display device including speaker assembly

1. A speaker assembly, comprising:

a first speaker;

a first connecting portion that is depressed at a side of the first speaker;

a first magnetic body provided at the first connecting portion;

a second speaker;

a second connecting portion that protrudes from a side of the second speaker and configured to be inserted into the first connecting portion; and

a second magnetic body provided at the second connecting portion and having a magnetic polarity different from a magnetic polarity of the first magnetic body,

wherein the first connecting portion includes:

a protrusion that protrudes adjacent to an edge of the first connecting portion toward an outside of the first speaker at an inclination; and

a depression depressed from the protrusion toward an inside of the first speaker at the inclination, and

wherein the second connecting portion includes:

a depression depressed adjacent to an edge of the second connecting portion toward an inside of the second speaker at the inclination; and

a protrusion that protrudes from the depression toward an outside of the second speaker at the inclination.

2. The speaker assembly of claim 1 , wherein at least one of the first magnetic body or the second magnetic body is a plurality of magnetic bodies.

3. The speaker assembly of claim 1 , wherein the first magnetic body includes a plurality of first sub-magnetic bodies having different magnetic polarities,

the second magnetic body includes a plurality of second sub-magnetic bodies having different magnetic polarities, and

the plurality of first sub-magnetic bodies and the plurality of second sub-magnetic bodies are alternately provided and provide an attractive force to couple the first connecting portion and the second connecting portion.

4. The speaker assembly of claim 1 , wherein the inclination is in a range of about 30° to 60°.

5. The speaker assembly of claim 1 , further including:

a first connector installed at the first speaker and exposed to an outside of the first connecting portion; and

a second connector installed at the second speaker and exposed to an outside of the second connecting portion, wherein the first connector is electrically connected to the second connector when the first speaker is coupled with the second speaker.

6. The speaker assembly of claim 5 , wherein the first connector is provided at a bottom of a sunken surface of the first connecting portion that is sunken into an inside of the first speaker, and the second connector is provided at a summit of an uplifted surface of the second connecting portion that is raised towards an outside of the second speaker.

7. The speaker assembly of claim 6 , wherein the first connecting portion includes a surface having an inclination different from an inclination direction of the sunken surface at an edge of the sunken surface, and the second connecting portion includes a surface having an inclination different from an inclination direction of the uplifted surface at an edge of the uplifted surface.

8. The speaker assembly of claim 7 , wherein the inclination is in a range of about 30° to 60°.

9. The speaker assembly of claim 6 , wherein when the first connecting portion is coupled to the second connecting portion through the first and second magnetic bodies, the summit is separated from the bottom.

10. The speaker assembly of claim 1 , wherein a depression depth of the first connecting portion is greater than a protrusion height of the second connecting portion.

11. The speaker assembly of claim 1 , wherein the first connecting portion is formed in a crater shape, and the second connecting portion is formed in a dome shape.

12. A display device, comprising:

a display head including a display panel; and

a speaker assembly configured to be separated from the display head, the speaker assembly including:

a first speaker;

a first connecting portion that forms a side of the first speaker;

a second speaker;

a second connecting portion that forms a side of the second speaker;

a first magnetic body provided at the first connecting portion; and

a second magnetic body provided at the second connecting portion and having a magnetic polarity different from a magnetic polarity of the first magnetic body,

wherein the first connecting portion includes an inclined surface, which is inclined toward an outside of the first speaker at an edge of the first connecting portion, and a depression, of which at a least a portion is sunken, and

wherein the second connecting portion includes an inclined surface, which is inclined toward an inside of the second speaker at an edge of the second connecting portion, and a protrusion, of which at a least a portion is uplifted.

13. The display device of claim 12 , further including:

a first connector embedded in the first speaker, provided at a bottom of the depression, and exposed to an outside of the first connecting portion; and

a second connector embedded in the second speaker, provided at a summit of the protrusion, and exposed to an outside of the second connecting portion.

14. The display device of claim 12 , wherein the first magnetic body includes a plurality of first sub-magnetic bodies, which have different magnetic polarities and are alternately provided, and the second magnetic body includes a plurality of second sub-magnetic bodies, which have different magnetic polarities and are alternately provided, such that the plurality of first sub-magnetic bodies and the plurality of second sub-magnetic bodies are attracted to each other.

15. The display device of claim 12 , wherein a depth of the depression is greater than a height of the protrusion when the first speaker is coupled with the second speaker.

16. The display device of claim 12 , wherein the inclined surfaces of the first and second connecting portions each have an inclination angle in a range of about 30° to 60°.
