Abstract

An electronic device is provided. The electronic device includes an electronic component including a coil therein, and a printed circuit board that is disposed to surround at least a part of the electronic component and includes plural slits disposed at preset intervals in at least one of regions facing the electronic component, wherein each of the plural slits may include a central slit portion extended along a center of the slit, and a symmetric slit portion extended to be symmetric with respect to the central slit portion.

First claim

What is claimed is:

1. An electronic device comprising:
an electronic component including a coil therein; and
a printed circuit board that is disposed to surround at least a part of the electronic component and includes plural slits disposed at preset intervals in at least one of regions facing the electronic component,
wherein each of the plural slits includes:
a central slit portion extended along a center of the slit, and
a symmetric slit portion extended to be symmetric with respect to the central slit portion.

2. The electronic device of claim 1 ,
wherein the printed circuit board includes:
a first region positioned to be spaced apart in a first direction of the electronic component and facing the electronic component;
a second region positioned to be spaced apart from the electronic component in a second direction opposite to the first direction and facing the electronic component; and
a third region positioned to be spaced apart from the electronic component in a third direction perpendicular to the first and second directions and facing the electronic component, and

wherein the plural slits are disposed at intervals in at least one region among the first region, the second region, and the third region.

3. The electronic device of claim 2 , wherein the plural slits are disposed at intervals in each of the first region, the second region, and the third region.

4. The electronic device of claim 2 , further comprising:
a battery disposed to be spaced apart from the printed circuit board in a length direction of the electronic device;
a battery connector disposed on the printed circuit board and electrically connecting the printed circuit board and the battery; and
a power consuming component disposed on the printed circuit board and receiving power from the battery,
wherein the plural slits are formed in a region positioned relatively close to the power consuming component compared to other regions among the first region, the second region, and the third region.

5. The electronic device of claim 1 , wherein the printed circuit board includes a cut region formed by cutting off a portion of the printed circuit board and where the electronic component is disposed.

6. The electronic device of claim 1 , wherein a portion of the printed circuit board includes a protrusion that is formed between plural slits and to protrude and extend in a direction toward the electronic component.

7. The electronic device of claim 1 ,
wherein the central slit portion is formed to extend in a direction away from the electronic component, and
wherein the symmetric slit portion is extended from one end of the central slit portion in a direction perpendicular to a direction where the central slit portion is extended so as to be symmetric with respect to the central slit portion.

8. The electronic device of claim 7 ,
wherein a portion of the printed circuit board includes a protrusion that is formed between plural slits and to protrude and extend in a direction toward the electronic component, and
wherein the protrusion includes:
a central protrusion portion in which a portion of the printed circuit board protrudes and extends in a direction perpendicular to a direction where the printed circuit board is extended; and
a symmetric protrusion portion formed to extend from one end of the central protrusion portion in a direction perpendicular to a direction where the central protrusion portion is extended in a form symmetric with respect to the central protrusion portion.

9. The electronic device of claim 1 , wherein the slit includes:
a concave portion formed in a shape in which one side and another side are concave toward a direction perpendicular to a direction where the slit is extended; and
a concave extension portion connected to the concave portion and extended from one end of the concave portion toward the printed circuit board in a direction away from the electronic component.

10. The electronic device of claim 9 ,
wherein a portion of the printed circuit board includes a protrusion that is formed between plural slits and to protrude and extend in a direction toward the electronic component, and
wherein the protrusion includes:
a central protrusion portion in which a portion of the printed circuit board protrudes and extends in a direction perpendicular to a direction where the printed circuit board is extended; and
a circular protrusion portion formed in a circular shape at one end of the central protrusion portion.

11. The electronic device of claim 1 ,
wherein the slits include:
a first slit including a central slit portion and a symmetric slit portion; and
a second slit formed to extend in a direction away from the electronic component, and

wherein the first slit and the second slit are alternately disposed at intervals in at least a region of the printed circuit board.

12. The electronic device of claim 11 ,
wherein a portion of the printed circuit board includes at least two protrusions that are formed between plural slits to protrude and extend in a direction toward the electronic component,
wherein the protrusion includes:
an extension portion in which a portion of the printed circuit board protrudes and extends in a direction toward the electronic component; and
a symmetric portion extended from one end of the extension portion in a direction perpendicular to a direction where the extension portion is extended,

wherein the at least two protrusions are disposed with a second slit interposed therebetween, and
wherein the at least two protrusions disposed with a second slit interposed therebetween are formed to be symmetrical to each other with respect to the second slit.

13. The electronic device of claim 1 , wherein the electronic component is a speaker or a receiver.

14. A printed circuit board comprising:
a cut region formed by cutting off a portion of the printed circuit board; and
a plurality of slits formed around the cut region,
wherein each of the plural slits includes:
a central slit portion extended along a center of the slit, and
a symmetric slit portion extended to be symmetric with respect to the central slit portion.

15. The printed circuit board of claim 14 , comprising:
a first region positioned in a first direction with respect to the cut region;
a second region positioned in a second direction opposite to the first direction with respect to the cut region; and
a third region positioned in a third direction perpendicular to the first and second directions with respect to the cut region,
wherein the plural slits are disposed at intervals in at least one region among the first region, the second region, and the third region.

16. The printed circuit board of claim 15 , wherein the plural slits are disposed at intervals in each of the first region, the second region, and the third region.

17. The printed circuit board of claim 14 ,
wherein the central slit portion is formed to extend in a direction away from the cut region, and
