Abstract

An electronic device and an accessory device for use therewith. The accessory device includes a first cover configured to detachably engage with the electronic device and cover at least a part of a second surface of the electronic device. A second member disposed on an inner or outer surface of the first cover includes a material attracted to at least one of a magnetic body or a magnet. Moreover, when seen from above the first cover in a direction perpendicular to the first cover, the second member is substantially at a center of the first cover. The accessory device further includes a second cover rotatably connected to the first cover and configured to open or close the first surface of the electronic device. In some embodiments, the electronic device includes a housing with a conductive pattern provided therein which is configured to wirelessly receive external power using the conductive pattern.

Claims

1. An electronic device comprising:

a housing having a first surface facing in a first direction and a second surface facing in a second direction opposite to the first direction;

a conductive pattern provided inside the housing;

a first member provided between separated portions of the conductive pattern, and comprising a material attracted to at least one of a magnetic body or a magnet;

a second member configured to at least partially overlap with the first member, when viewed from above the housing, apart from the first member in the first or second direction, and comprising a material attracted to a magnetic body or a magnet; and

a circuit connected electrically to the conductive pattern and configured to wirelessly receive external power using the conductive pattern.

2. The electronic device of claim 1, wherein at least one of the first member or the second member comprises an amorphous metallic material.

3. The electronic device of claim 2, wherein the amorphous metallic material is an Fe-based amorphous alloy, a Co-based amorphous alloy, or a nanocrystalline alloy.

4. The electronic device of claim 3, wherein the amorphous metallic material is the Fe-based amorphous alloy comprising an Fe—

Si—

B alloy or an Fe—

Si—

B—

Co alloy.

5. The electronic device of claim 3, wherein the amorphous metallic material is the nanocrystalline alloy comprising an Fe—

Si—

B—

Cu—

Nb alloy.

6. The electronic device of claim 1, wherein the first member and the second member are formed of a same material.

7. The electronic device of claim 1, wherein the first member or the second member is disposed substantially at a center of the housing, when seen from above the housing.

8. The electronic device of claim 1, further comprising a first cover configured to cover at least a part of the second surface of the housing,

wherein the second member is disposed on the first cover.

9. The electronic device of claim 8, wherein the first cover is detachably engaged with the housing.

10. An accessory device comprising:

a first cover configured to detachably engage with an electronic device and cover at least a part of a second surface of the electronic device; and

a second member disposed on an inner or outer surface of the first cover and comprising a material attracted to at least one of a magnetic body or a magnet,

wherein when seen from above the first cover, the second member is disposed substantially at a center of the first cover.

11. The accessory device of claim 10, wherein the accessory device further includes a second cover configured to cover at least a part of a first surface of the electronic device.

12. The accessory device of claim 11, wherein the second cover is rotatably connected to the first cover and is configured to open or close the first surface of the electronic device by rotating with respect to the first cover.

13. The accessory device of claim 11, wherein when the first cover is engaged with the electronic device, the second cover is configured to at least partially overlap with a first member in the electronic device comprising a material attracted to at least one of a magnetic body or a magnet, when seen from above the first cover.

14. An accessory device comprising:

a cover unit configured to cover at least a part of an electronic device; and

a second member disposed on the cover unit and attracted to a magnetic body,

wherein if the cover unit is placed on a wireless charger, the second member is attracted to a magnetic body in the wireless charger, and configured to align the cover unit on the wireless charger.

15. The accessory device of claim 14, wherein the second member comprises an amorphous metallic material.

16. The accessory device of claim 14, wherein when the cover unit covers the at least a part of the electronic device, the second member is disposed on the cover unit in correspondence with a first member in the electronic device that is attracted to a magnetic body.

17. The accessory device of claim 14, wherein the cover unit comprises:

a first cover configured to cover at least a part of a second surface of the electronic device; and

a second cover configured to open or close at least a part of a first surface of the electronic device, and

wherein the second member is provided on at least one of the first cover or the second cover.

18. The accessory device of claim 17, wherein the second cover is further configured to:

rotatably connect to the first cover; and

open or close the first surface of the electronic device by rotating with respect to the first cover.

19. The accessory device of claim 14, further comprising an attachment portion surrounding the second member, and configured to attach the second member onto the cover unit.

20. An electronic device comprising:

a housing;

a cover unit configured to cover at least a part of the housing; and

a second member disposed on the cover unit and attracted to a magnetic body, wherein if the cover unit is placed on a wireless charger, the second member is attracted to a magnetic body provided in the wireless charger, thereby aligning the cover unit on the wireless charger.
