CASE AND APPARATUS INCLUDING THE SAME
A case includes a casing region made of metal and configured to cover at least a portion of an apparatus, and a coil electrically insulated from the casing region and having a ring shape or a polygonal shape having ends separated from each other, the coil being configured to be disposed outside the apparatus.
1 . A case comprising:
a casing region made of metal and configured to cover at least a portion of an apparatus; and
a coil electrically insulated from the casing region and having a ring shape or a polygonal shape having ends separated from each other, the coil being configured to be disposed outside the apparatus.
2 . The case of claim 1 , wherein the casing region comprises a region corresponding to a rear surface of the apparatus.
3 . The case of claim 2 , wherein the coil is configured to substantially surround an edge of the apparatus.
4 . The case of claim 2 , wherein the coil is disposed in a position corresponding to an edge of the rear surface of the apparatus.
5 . The case of claim 1 , wherein the coil is constituted by a single conductive wire.
6 . The case of claim 1 , wherein the coil comprises two or more turns.
7 . The case of claim 1 , wherein the coil has a length of 95% or more of a length of an edge of the casing region.
8 . The case of claim 1 , further comprising an insulating portion disposed between the casing region and the coil.
9 . The case of claim 1 , wherein the coil is configured to receive power wirelessly.
10 . The case of claim 1 , wherein the coil is configured to receive or transmit data wirelessly.
11 . An apparatus comprising:
a body; and
a case comprising:
a casing region made of metal and covering at least a portion of the body; and
a coil electrically insulated from the casing region and having a ring shape or a polygonal shape having ends separated from each other, the coil being disposed outside the body.
12 . The apparatus of claim 11 , wherein the body comprises a wireless charging module configured to rectify power wirelessly received through the coil to charge a battery with power.
13 . The apparatus of claim 11 , wherein the body comprises a near-field communication (NFC) module configured to transmit and receive data through the coil.
14 . The apparatus of claim 11 , wherein the body comprises:
a wireless charging module configured to rectify power wirelessly received through the coil to charge a battery with power;
a near-field communication (NFC) module configured to transmit and receive data through the coil; and
a switch portion configured to selectively connect the coil to the NFC module or the wireless charging module in response to a signal received by the coil.
15 . The apparatus of claim 11 , wherein the coil substantially surrounds an edge of the body.
16 . The apparatus of claim 11 , wherein the coil is disposed along an edge of a rear surface of the body.
17 . A case of an apparatus, the case comprising:
a metal portion constituting at least a portion of a rear surface of the apparatus; and
a coil electrically insulated from the metal portion and constituting a portion of an exterior surface of the apparatus.
18 . The case of claim 17 , wherein the coil has two ends separated by a gap, and constitutes a portion of an edge surface of the apparatus, or a portion of the rear surface of the apparatus substantially surrounding the metal portion.
19 . The case of claim 17 , wherein the coil constitutes a portion of an edge surface of the apparatus; and
the case further comprises an insulating portion constituting another portion of the side surface of the apparatus and being disposed between the coil and the metal portion to electrically insulate the coil from the metal portion.
20 . The case of claim 17 , wherein the coil constitutes another portion of the rear surface of the apparatus substantially surrounding the metal portion; and
the case further comprises an insulating portion constituting another portion of the rear surface of the apparatus and being disposed between the coil and the metal portion to electrically insulate the coil from the metal portion.
