[0094] The present disclosure relates to a device that can be detachably coupled to an electronic device.

[0095] For example, the electronic device (101) may include a camera module (184) and a battery (171). At least a portion of the camera module (184) may be exposed to the outside through the rear cover of the electronic device (101). The electronic device (101) may be configured to wirelessly charge the battery (171). The electronic device (101) may include an induction coil for wirelessly charging the battery (171). The induction coil may be formed as a substantial plane, but is not limited thereto. The electronic device (101) may transmit power to another electronic device through the induction coil.

[0096] FIG. 2 is a perspective view showing an apparatus according to one or more embodiments of the present disclosure. FIG. 3 is a rear perspective view showing an apparatus according to one or more embodiments of the present disclosure.

[0097] Referring to FIG. 2 and FIG. 3, an apparatus (1) according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0098] The case (10) may be formed to be detachably coupled to the electronic device (101) (see FIG. 1 and FIG. 25). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). For example, if the electronic device (101) has a rectangular flat shape, the case (10) may be formed in a basket shape having a roughly rectangular cross-section to accommodate the electronic device (101). However, the shape of the case (10) is not limited thereto. The case (10) may be formed in various shapes (e.g., a shape with at least a part curved) corresponding to the shape of the electronic device (101).

[0099] According to one embodiment, the case (10) may include a bottom (11) and four side walls (13). The bottom (11) is formed as a roughly rectangular flat plate, and the four side walls (13) may be formed by extending vertically from four sides of the bottom (11).

[0100] According to one embodiment, the case (10) may include a first surface (11a) facing a first direction (e.g., -Z-axis direction) and in contact with an electronic device (101), and a second surface (11b) facing a second direction (e.g., +Z-axis direction) opposite to the first direction. For example, one side of the bottom (11) to which the four side walls (13) of the case (10) extend is the first surface (11a), and the opposite side of the bottom (11) corresponds to the second surface (11b).

[0101] The case (10) may include a camera opening (12). The camera opening (12) may be formed so that at least a portion of the camera module (184) of the electronic device (101) is exposed to the outside when the electronic device (101) is coupled to the case (10). For example, the camera opening (12) may be formed in the bottom (11) of the case (10). The camera opening (12) may be provided to overlap with the camera module (184) (e.g., a plurality of cameras having a specified arrangement) provided in the electronic device (101). In one embodiment, the camera opening (12) may be formed as an elongated ellipse in the Y-axis direction. However, the shape of the camera opening (12) is not limited thereto. The camera opening (12) may be provided in various shapes (e.g., a rectangle elongated in the X-axis direction, a substantial square) corresponding to the shape, size, position, and arrangement of the camera module (184) of the electronic device (101). For example, the camera opening (12) may include a plurality of openings corresponding to each lens of a plurality of cameras included in the camera module (184).

[0102] According to one embodiment, a transparent plate (e.g., a transparent window) may be installed in the camera opening (12). The transparent plate installed in the camera opening (12) may cover the camera module (184) of the electronic device (101).

[0103] The magnetic structure (20) may be formed to provide an attractive force that is coupled to an external magnetic structure (203) of an external electronic device (200) (see FIG. 32). For example, the external electronic device may be a charging station (200) capable of charging a battery (171) (see FIG. 1) of an electronic device (101), and the external magnetic structure (203) may be a magnetic structure (203) that is placed in the charging station (200) and can be coupled by magnetic force to a magnetic structure (20) of a device (1) according to one or more embodiments of the present disclosure.

[0104] The magnetic structure (20) may be placed in the case (10). The magnetic structure (20) may be placed outside the case (10). The magnetic structure (20) may be embedded in the case (10) (e.g., placed between the first surface (11a) and the second surface (11b)). For example, the magnetic structure (20) may be placed on the second surface (11b) of the case (10). According to one embodiment, the magnetic structure (20) may be placed adjacent to the camera opening (12) on the first surface (11a) of the case (10).

[0105] The magnetic structure (20) may be formed to surround the planar induction coil (303) (see FIG. 25) of the electronic device (101) when the case (10) is coupled to the electronic device (101). For example, the magnetic structure (20) may be formed in a loop shape (or ring shape, ring shape) that can surround the planar induction coil (303) of the electronic device (101). The magnetic structure (20) may be formed in an unsegmented loop shape. However, the shape of the magnetic structure (20) is not limited thereto. The magnetic structure (20) may be formed in various shapes (e.g., elliptical, square) corresponding to the shape of the planar induction coil (303) of the electronic device (101).

[0106] According to one embodiment, the magnetic structure (20) may include an outer magnet (21), a non-magnetic part (23), and an inner magnet (22). The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be formed in a circular loop shape. The magnetic structure (20) may include a gap region in which a portion of the circular loop shape is empty. The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be formed to have a rectangular cross-section.

[0107] The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be arranged concentrically. The non-magnetic part (23) may be arranged around the inner magnet (22), and the outer magnet (21) may be arranged around the non-magnetic part (23). The outer surface of the inner magnet (22) may come into contact with the inner surface of the non-magnetic part (23). The outer surface of the non-magnetic part (23) may come into contact with the inner surface of the outer magnet (21).

[0108] The inner magnet (22) and the outer magnet (21) can be formed of permanent magnets. The non-magnetic part (23) can be formed of a non-magnetic material.

[0109] According to one embodiment, the inner magnet (22) and the outer magnet (21) may be magnetized in a vertical direction. The magnetic direction of the inner magnet (22) may be opposite to the magnetic direction of the outer magnet (21).

[0110] The magnetic shielding member (30) may be formed such that the magnetic force of the magnetic structure (20) in at least one direction is reduced. The magnetic field produced by the magnetic structure (20) may be partially reduced by the magnetic shielding member (30). The magnetic shielding member (30) may be formed in a shape corresponding to the magnetic structure (20). For example, the magnetic shielding member (30) may be formed in a circular loop shape. The magnetic shielding member (30) may include a gap region (e.g., the opening (34) in FIG. 4) in which a portion of the circular loop shape is empty. The gap region may be an empty space, or at least partially filled with a material different from the magnetic shielding member (30) (e.g., an insulator, a magnetic material, an adhesive). According to one embodiment, the magnetic shielding member (30) may be embedded in the case (10) (e.g., placed between the first surface (11a) and the second surface (11b)).

[0111] According to one embodiment, the magnetic shielding member (30) may include a first part (31) and a second part (32).

[0112] For example, a first part (31) of the magnetic shielding member (30) may be placed on a second surface (11b) of the case (10). The first part (31) may be formed to cover one surface (20a) (see FIG. 5) of the magnetic structure (20). The first part (31) and the magnetic structure (20) may overlap in the Z-axis direction. For example, the first part (31) may be formed in a circular loop shape having a rectangular cross-section corresponding to the magnetic structure (20).

[0113] A first portion (31) of the magnetic shielding member (30) may be interposed between the second surface (11b) of the case (10) and the magnetic structure (20). Thus, when an electronic device (101) is coupled to the case (10), the first portion (31) of the magnetic shielding member (30) may cover one surface (20a) (see FIG. 5) of the magnetic structure (20) adjacent to the electronic device (101).

[0114] For example, a second part (32) of the magnetic shielding member (30) may be formed to cover the outer surface (20c) (see FIG. 5) of the magnetic structure (20). The second part (32) may be arranged to face the camera opening (12). When the electronic device (101) is coupled to the case (10), the second part (32) may be positioned to shield at least a portion of the magnetic force of the magnetic structure (20) acting on the camera module (184) of the electronic device (101). For example, the second part (32) may be formed to limit at least a portion of the magnetic field in the direction of the camera opening (12) among the magnetic fields generated by the magnetic structure (20).

[0115] For example, the second part (32) may be formed to cover the entire outer surface (20c) of the magnetic structure (20). In other words, the second part (32) may be formed to cover the entire circumference of the outer surface of the outer magnet (21) of the magnetic structure (20). For example, the second part (32) may be formed to cover a portion of the outer surface (20c) of the magnetic structure (20). According to one embodiment, the second part (32) may be formed to cover a portion of the outer surface (20c) of the magnetic structure (20) adjacent to the camera opening (12). Here, the range of the outer surface (20c) of the magnetic structure (20) covered by the second part (32) of the magnetic shielding member (30) can be determined by the influence of the magnetic field of the magnetic structure (20) acting on the camera module (184) of the electronic device (101) when the electronic device (101) is coupled to the case (10).

[0116] For example, the second part (32) can be extended from the outer end (31a) (see FIG. 5) of the first part (31) and bent to cover the outer surface (20c) of the magnetic structure (20).

[0117] According to one embodiment, the magnetic shielding member (30) may further include a third part (33) formed to extend from the inner end (31b) (see FIG. 5) of the first part (31) and cover the inner surface (20d) (see FIG. 5) of the magnetic structure (20). The third part (33) may be positioned to shield at least a portion of the magnetic force of the magnetic structure (20) acting on the planar induction coil (303) of the electronic device (101). For example, the third part (33) may be formed to limit at least a portion of the magnetic field in the direction of the planar induction coil (303) of the electronic device (101) among the magnetic fields generated by the magnetic structure (20).

[0118] For example, the third part (33) may be formed to cover the entire inner surface (20d) of the magnetic structure (20). In other words, the third part (33) may be formed to cover the entire circumference of the inner surface of the inner magnet (22) of the magnetic structure (20). For example, the third part (33) may be formed to cover a portion of the inner surface (20d) of the magnetic structure (20).

[0119] For example, the third part (33) may be extended from the inner end (31b) (see FIG. 5) of the first part (31) and bent to cover the inner surface (20d) of the magnetic structure (20). The height (h2) of the third part (33) may be formed to be the same as the height (h1) of the second part (32).

[0120] The magnetic shielding member (30) can be formed from cold-rolled steel plate (e.g., SPCC, steel plate cold commercial), rolled galvanized steel plate (GI, galvanized iron), hot-rolled steel plate (e.g., SPHC, steel plate hot rolled coil), or a nanocrystalline shielding material (e.g., 1K-107B).

[0121] According to one embodiment, the case (10) may further include an additional magnetic shielding member (17). The additional magnetic shielding member (17) may be positioned to surround at least a portion of the camera opening (12). The additional magnetic shielding member (17) may be formed of the same material as the magnetic shielding member (30). The additional magnetic shielding member (17) may be formed to further reduce the magnetic force applied from the magnetic structure (20) toward the camera opening (12).

[0122] FIG. 4 is a drawing showing an apparatus according to one or more embodiments of the present disclosure. FIG. 5 is a partial cross-sectional view showing the apparatus of FIG. 4 according to one or more embodiments of the present disclosure, cut along line AA. FIG. 6 is a partial cross-sectional view showing the apparatus of FIG. 4 according to one or more embodiments of the present disclosure, cut along line AA. FIG. 7 is a partial cross-sectional view showing the apparatus of FIG. 4 according to one or more embodiments of the present disclosure, cut along line BB.

[0123] Referring to FIGS. 4 to 7, an apparatus (1) according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0124] The case (10) may be formed to be detachably coupled to the electronic device (101). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). Since the case (10) is identical to the case (10) of the embodiment of FIGS. 2 and FIG. 3 described above, a redundant description is omitted.

[0125] The case (10) may include a camera opening (12). The camera opening (12) may be formed so that at least a portion of the camera module (184) of the electronic device (101) is exposed to the outside when the electronic device (101) is coupled to the case (10). For example, the camera opening (12) may be formed on the bottom (11) of the case (10). Thus, when the case (10) is coupled to the electronic device (101), the camera module (184) of the electronic device (101) may be located in the camera opening (12) of the case (10).

[0126] The magnetic shielding member (30) can be formed so as to limit the magnetic force of at least one direction of the magnetic structure (20).

[0127] The magnetic shielding member (30) may be formed to surround the planar induction coil (303) (see FIG. 25) of the electronic device (101) when the case (10) is coupled to the electronic device (101) and the second surface (11b) of the case (10) is viewed from the electronic device (101). For example, the magnetic structure (20) may be formed in a loop shape that can surround the planar induction coil (303) of the electronic device (101).

[0128] For example, the magnetic shielding member (30) may be formed in a circular loop shape. The cross-section of the magnetic shielding member (30) may be formed in a U-shape with a roughly flat bottom.

[0129] For example, a magnetic shielding member (30) may be placed on the second surface (11b) of the case (10). The magnetic shielding member (30) may be attached to the second surface (11b) of the case (10) with an adhesive member (35). For example, double-sided tape may be used as the adhesive member (35). A magnetic structure (20) may be placed inside the magnetic shielding member (30).

[0130] According to one embodiment, the magnetic shielding member (30) may include a first part (31), a second part (32), and a third part (33).

[0131] The first part (31) may be placed on the second surface (11b) of the case (10). The first part (31) may be formed to cover the lower surface (20a) of the magnetic structure (20). The first part (31) may be interposed between the second surface (11b) of the case (10) and the magnetic structure (20). Thus, when an electronic device (101) is coupled to the case (10), the first part (31) of the magnetic shielding member (30) may cover the lower surface (20a) of the magnetic structure (20) adjacent to the electronic device (101).

[0132] The second part (32) may be formed to cover the outer surface (20c) of the magnetic structure (20). The second part (32) may be extended from the outer end (31a) of the first part (31) and bent to cover the outer surface (20c) of the magnetic structure (20). The second part (32) may be formed to cover the entire outer surface (20c) of the magnetic structure (20). At least a portion of the second part (32) may be arranged to face the camera opening (12). Thus, the second part (32) may limit at least a portion of the magnetic field in the direction of the camera opening (12) among the magnetic fields generated by the magnetic structure (20).

[0133] The third part (33) may be formed to cover the inner surface (20d) of the magnetic structure (20). The third part (33) may be extended from the inner end (31b) of the first part (31) and bent to cover the inner surface (20d) of the magnetic structure (20). The third part (33) may be formed to cover the entire inner surface (20d) of the magnetic structure (20). Thus, the third part (33) may limit at least a portion of the magnetic field in the direction of the planar induction coil (303) of the electronic device (101) among the magnetic fields generated by the magnetic structure (20).

[0134] The third part (33) can be arranged concentrically with the second part (32). The height (h2) of the third part (33) can be formed to be the same as the height (h1) of the second part (32).

[0135] According to one embodiment, the thickness of the second part (32) and / or the third part (33) may vary depending on the height. For example, the outer or inner surface of the magnetic shielding member (30) may have a slanted shape.

[0136] The magnetic structure (20) may be placed in the magnetic shielding member (30). For example, at least a portion of the magnetic structure (20) may be accommodated in the magnetic shielding member (30). Thus, a first portion (31) of the magnetic shielding member (30) may cover the lower surface (20a) of the magnetic structure (20), a second portion (32) may cover the outer surface (20c) of the magnetic structure (20), and a third portion (33) may cover the inner surface (20d) of the magnetic structure (20). The upper surface (20b) of the magnetic structure (20) may not be covered by the magnetic shielding member (30). The upper surface (20b) of the magnetic structure (20) may face an external magnetic structure (203) (see FIG. 29) of an external electronic device (200) (see FIG. 29).

[0137] According to one embodiment, the magnetic structure (20) may include a plurality of magnetic segments (20S). The plurality of magnetic segments (20S) may be formed in an arc shape. The plurality of magnetic segments (20S) may be arranged in a circular loop shape.

[0138] A plurality of magnetic segments (20S) may be formed to provide an attractive force that is coupled to an external magnetic structure (203) (see FIG. 29) of an external electronic device (200) (see FIG. 29). A plurality of magnetic segments (20S) may be formed to have the same magnetic pole arrangement.

[0139] A plurality of magnetic segments (20S) may be formed with the same shape. Each of the plurality of magnetic segments (20S) may include an inner magnet (22), a non-magnetic part (23), and an outer magnet (21). The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may each be formed, for example, into an arc shape with substantially the same radius of curvature. The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be formed to have a rectangular cross-section.

[0140] The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be arranged concentrically. The non-magnetic part (23) may be placed on the outer surface of the inner magnet (22), and the outer magnet (21) may be placed on the outer surface of the non-magnetic part (23).

[0141] The inner magnet (22) and the outer magnet (21) can be formed of permanent magnets. The non-magnetic part (23) can be formed of a non-magnetic material.

[0142] According to one embodiment, the inner magnet (22) and the outer magnet (21) may be magnetized in a vertical direction. The magnetic direction of the inner magnet (22) may be opposite to the magnetic direction of the outer magnet (21). For example, the outer magnet (21) may have its N pole located at the bottom (e.g., -Z direction) and its S pole located at the top (e.g., +Z direction). The inner magnet (22) may have its S pole located at the bottom (e.g., -Z direction) and its N pole located at the top (e.g., +Z direction).

[0143] According to one embodiment, the width (W2) of the inner magnet (22) may be wider than the width (W1) of the outer magnet (21). The width (W1) of the outer magnet (23) may be the same as the width (W3) of the non-magnetic part (23). However, the width (W2) of the inner magnet (22), the width (W3) of the non-magnetic part (23), and the width (W1) of the outer magnet (21) are not limited thereto. For example, the width (W2) of the inner magnet (22) may be formed to be the same as or narrower than the width (W1) of the outer magnet (21). The width (W2) of the inner magnet (22) may be formed to be wider than the width (W3) of the non-magnetic part (23).

[0144] According to one embodiment, the width (W1) of the outer magnet (21) of the magnetic structure (20), the width (W3) of the non-magnetic part (23), and the width (W2) of the inner magnet (22) can be determined in various ratios as needed.

[0145] According to one embodiment, the magnetic segments (20S) may be formed with different widths and / or heights for the inner magnet (22), the non-magnetic part (23), and / or the outer magnet (21). For example, the width (W1) of the outer magnet (21) of the magnetic segment (20S) adjacent to the camera opening (12) may be smaller than the width (W1) of the outer magnet (21) of another magnetic segment (20S).

[0146] Referring to FIG. 6, the magnetic shielding member (30) can be attached to the second surface (11b) of the case (10) with an adhesive member (35). The magnetic structure (20), i.e., a plurality of magnetic segments (20S), can be attached to the first part (31) of the magnetic shielding member (30) with an adhesive member (36). For example, double-sided tape can be used as the adhesive members (35, 36). For reference, in other drawings of this specification, the adhesive member (35) for attaching the magnetic shielding member (30) to the case (10) and the adhesive member (36) for attaching the magnetic structure (20) to the magnetic shielding member (30) are not shown for convenience of illustration.

[0147] According to one embodiment, the magnetic structure (20) may include a sensing magnet (40). The sensing magnet (40) may be formed in a shape similar to the magnetic segment (20S). As shown in FIG. 4, the sensing magnet (40) may form a circular loop together with a plurality of magnetic segments (20S).

[0148] The sensing magnet (40) can be formed so that it can be recognized by the Hall sensor (305) (see FIG. 25) of the electronic device (101). For example, the sensing magnet (40) can be formed as shown in FIG. 7.

[0149] The sensing magnet (40) may include an outer sensing magnet (41) and an inner sensing magnet (42). The inner sensing magnet (42) and the outer sensing magnet (41) may each be formed in an arc shape. The inner sensing magnet (42) and the outer sensing magnet (41) may be formed to have a rectangular cross-section.

[0150] The inner sensing magnet (42) and the outer sensing magnet (41) can be arranged concentrically. The outer sensing magnet (41) can be arranged on the outer surface of the inner sensing magnet (42).

[0151] The inner sensing magnet (42) and the outer sensing magnet (41) can be formed as permanent magnets.

[0152] According to one embodiment, the inner sensing magnet (42) and the outer sensing magnet (41) may be magnetized in a vertical direction. The magnetic direction of the inner sensing magnet (42) may be opposite to the magnetic direction of the outer sensing magnet (41). For example, the outer sensing magnet (41) may have its N pole located at the bottom (e.g., -Z direction) and its S pole located at the top (e.g., +Z direction). The inner sensing magnet (42) may have its S pole located at the bottom (e.g., -Z direction) and its N pole located at the top (e.g., +Z direction).

[0153] According to one embodiment, a magnetic segment (20S) providing an attractive force that is coupled to an external magnetic structure (203) (see FIG. 29) of an external electronic device (200) (see FIG. 29) is magnetized in a vertical direction, and a sensing magnet (40) providing a magnetic field that is detected by the device (1) through a Hall sensor (305) of the electronic device (101) can be magnetized in a horizontal direction. For example, the sensing magnet (40) may include a magnet that is horizontally magnetized with an N pole in the outer direction and an S pole in the inner direction.

[0154] According to one embodiment, a non-magnetic portion or gap region may be included between the magnetic segment (20S) that provides an attractive force coupled with an external magnetic structure (203) (see FIG. 29) and the sensing magnet (40).

[0155] For example, the width (W5) of the inner sensing magnet (42) may be the same as the width (W4) of the outer sensing magnet (41). For example, the width (W4) of the outer sensing magnet (41) of the sensing magnet (40) may be larger than the width (W1) of the outer magnet (21) of the other magnet segment (20S).

[0156] According to one embodiment, the magnetic shielding member (30) may include an opening (34). A portion of the magnetic structure (20) may be exposed through the opening (34) of the magnetic shielding member (30). The opening (34) may be formed at a position corresponding to the sensing magnet (40) of the magnetic structure (20). For example, the magnetic shielding member (30) may be formed as a circular loop with a portion cut out. Thus, the sensing magnet (40) may be exposed through the opening (34) of the magnetic shielding member (30). Then, since the magnetic field of the sensing magnet (40) is not blocked by the magnetic shielding member (30), the Hall sensor (305) of the electronic device (101) can detect the sensing magnet (40).

[0157] According to one embodiment, the magnetic shielding member (30) may include a plurality of openings. Among two or more openings, the first opening may be positioned in a location overlapping with the sensing magnet (40), and the second opening may be positioned in a location overlapping with a component or circuit of the electronic device (101) (e.g., wiring connected to the planar induction coil (303) of the electronic device (101)).

[0158] FIG. 8 is a partial cross-sectional view showing an apparatus according to one or more embodiments of the present disclosure.

[0159] According to one embodiment, as shown in FIG. 8, the thicknesses of the second part (32) and the third part (33) of the magnetic shielding member (30) can be formed differently.

[0160] Referring to FIG. 8, the magnetic shielding member (30) may include a first part (31) covering the lower surface (20a) of the magnetic structure (20), a second part (32) extending substantially vertically upward from the outer end (31a) of the first part (31) and covering the outer surface (20c) of the magnetic structure (20), and a third part (33) extending substantially vertically upward from the inner end (31b) of the first part (31) and covering the inner surface (20d) of the magnetic structure (20).

[0161] For example, the thickness (t1) of the second part (32) can be formed to be thicker than the thickness (t2) of the third part (33). By making the thickness (t1) of the second part (32) thicker, the magnetic force of the magnetic structure (20) applied to the camera module (184) of the electronic device (101) mounted in the camera opening (12) of the case (10) can be further reduced. Therefore, since the malfunction of the camera module (184) of the electronic device (101) can be prevented, the reliability of the electronic device (101) can be improved.

[0162] According to one embodiment, the magnetic shielding member (30) may have a second portion (32) that is thicker than other portions only in some portions (e.g., the area covering the magnetic segment (20S) facing the camera opening (13).

[0163] According to one embodiment, as shown in FIG. 36, the height (or thickness) (h) of the magnetic structure (20) can be formed to be greater than the height (h1) of the second part (32) and the height (h2) of the third part (33) of the magnetic shielding member (30).

[0164] FIG. 36 is a partial cross-sectional view showing an apparatus according to one or more embodiments of the present disclosure.

[0165] Referring to FIG. 36, the magnetic shielding member (30) may include a first part (31) covering the lower surface (20a) of the magnetic structure (20), a second part (32) extending substantially vertically upward from the outer end (31a) of the first part (31) and covering the outer surface (20c) of the magnetic structure (20), and a third part (33) extending substantially vertically upward from the inner end (31b) of the first part (31) and covering the inner surface (20d) of the magnetic structure (20).

[0166] For example, the height (h1) of the second part (32) and the height (h2) of the third part (33) can be formed lower than the height (h) of the magnetic structure (20). Accordingly, the upper surface (32a) of the second part (32) and the upper surface (33a) of the third part (33) can be located below the upper surface (20b) of the magnetic structure (20) to form a step.

[0167] The height (h1) of the second part (32) may be the same as or different from the height (h2) of the third part (33).

[0168] If the height (h) of the magnetic structure (20) is made higher than the heights (h1, h2) of the second part (32) and the third part (33) of the magnetic shielding member (30), the inductance of the planar induction coil (303) (see FIG. 25) of the electronic device (101) (see FIG. 25) can be increased.

[0169] According to one embodiment, as shown in FIGS. 37 and 38, the height (h1) of the second part (32) and the height (h2) of the third part (33) of the magnetic shielding member (30) can be formed differently.

[0170] FIG. 37 is a partial cross-sectional view showing an apparatus according to one or more embodiments of the present disclosure.

[0171] Referring to FIG. 37, the magnetic shielding member (30) may include a first part (31) covering the lower surface (20a) of the magnetic structure (20), a second part (32) extending substantially vertically upward from the outer end (31a) of the first part (31) and covering the outer surface (20c) of the magnetic structure (20), and a third part (33) extending substantially vertically upward from the inner end (31b) of the first part (31) and covering the inner surface (20d) of the magnetic structure (20).

[0172] For example, the height (h1) of the second part (32) may be formed higher than the height (h2) of the third part (33). The height (h1) of the second part (32) may be formed substantially the same as the height (h) of the magnetic structure (20). In other words, the upper surface (32a) of the second part (32) and the upper surface (20b) of the magnetic structure (20) may form a plane. The height (h2) of the third part (33) may be formed lower than the height (h) of the magnetic structure (20). In other words, the upper surface (33a) of the third part (33) may be located below the upper surface (20b) of the magnetic structure (20) to form a step.

[0173] For example, the height (h1) of the second part (32) can be formed to be lower than the height (h) of the magnetic structure (20) and higher than the height (h2) of the third part (33).

[0174] For example, the second part (32) may be formed such that a portion of its height (h1) is higher than the height (h2) of the third part (33), and the remaining portion has a height equal to or lower than the height (h2) of the third part (33).

[0175] By increasing the height (h1) of the second part (32), the magnetic force of the magnetic structure (20) applied to the camera module (184) (see FIG. 24) of the electronic device (101) (see FIG. 24) mounted in the camera opening (12) of the case (10) can be reduced. Therefore, since the malfunction of the camera module (184) of the electronic device (101) can be prevented, the reliability of the electronic device (101) can be improved.

[0176] FIG. 38 is a partial cross-sectional view showing an apparatus according to one or more embodiments of the present disclosure.

[0177] Referring to FIG. 38, the magnetic shielding member (30) may include a first part (31) covering the lower surface (20a) of the magnetic structure (20), a second part (32) extending substantially vertically upward from the outer end (31a) of the first part (31) and covering the outer surface (20c) of the magnetic structure (20), and a third part (33) extending substantially vertically upward from the inner end (31b) of the first part (31) and covering the inner surface (20d) of the magnetic structure (20).

[0178] For example, the height (h2) of the third part (33) can be formed higher than the height (h1) of the second part (32). The height (h2) of the third part (33) can be formed substantially the same as the height (h) of the magnetic structure (20). In other words, the upper surface (33a) of the third part (33) and the upper surface (20b) of the magnetic structure (20) can form the same plane. The height (h1) of the second part (32) can be formed lower than the height (h) of the magnetic structure (20). In other words, the upper surface (32a) of the second part (32) can be located below the upper surface (20b) of the magnetic structure (20) to form a step.

[0179] For example, the height (h2) of the third part (33) can be formed to be lower than the height (h) of the magnetic structure (20) and higher than the height (h1) of the second part (32).

[0180] For example, the third part (33) may be formed such that a portion of its height (h2) is higher than the height (h1) of the second part (32), and the remaining portion has a height equal to or lower than the height (h1) of the second part (32).

[0181] The height (h2) of the third part (32) can be set to shield at least a portion of the magnetic force of the magnetic structure (20) acting on the planar induction coil (303) (see FIG. 25) of the electronic device (101) (see FIG. 25). For example, the height (h2) of the third part (33) can be set to limit at least a portion of the magnetic field in the direction of the planar induction coil (303) of the electronic device (101) among the magnetic fields generated by the magnetic structure (20), thereby preventing the shielding material of the planar induction coil (303) of the electronic device (101) from being magnetized.

[0182] According to one embodiment, the second part (32) and the third part (33) of the magnetic shielding member (30) may be formed of different materials. For example, the second part (32) covering the outer surface (20c) of the magnetic structure (20) may be formed of a ferromagnetic material with high magnetic shielding performance, and the third part (33) covering the inner surface (20d) of the magnetic structure (20) may be formed of a soft magnetic material with low magnetic shielding performance. In other words, the second part (32) of the magnetic shielding member (30) may be formed of the same ferromagnetic material as the first part (31), and the third part (33) may be formed of a soft magnetic material different from the first part (31).

[0183] For example, the first part (31) and the second part (32) of the magnetic shielding member (30) may be formed from a ferromagnetic material such as cold-rolled steel sheet, and the third part (33) may be formed from a soft magnetic material such as iron, permalloy, sendust, or silicon steel sheet.

[0184] If the second part (32) of the magnetic shielding member (30) is formed of a ferromagnetic material and the third part (33) is formed of a soft magnetic material, the magnetic field of the magnetic structure (20) acting on the camera module (184) of the electronic device (101) can be effectively shielded, and wireless charging performance through the interior of the magnetic shielding member (30) can be improved.

[0185] FIG. 9 is a partial view showing an apparatus according to one or more embodiments of the present disclosure. FIG. 10 is a partial cross-sectional view showing the apparatus of FIG. 9 according to one or more embodiments of the present disclosure, cut along line CC.

[0186] Referring to FIGS. 9 and FIGS. 10, an apparatus according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0187] The case (10) may be formed to be detachably coupled to the electronic device (101). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). Since the case (10) is identical to the case (10) of FIGS. 2 and FIGS. 3 described above, a redundant description is omitted.

[0188] The magnetic shielding member (30) can be formed to shield at least a portion of the magnetic force in at least one direction of the magnetic structure (20).

[0189] The magnetic shielding member (30) may be formed to surround the planar induction coil (303) (see FIG. 25) of the electronic device (101) when the case (10) is coupled to the electronic device (101). For example, the magnetic shielding member (30) may be formed in a loop shape that can surround the planar induction coil (303) of the electronic device (101).

[0190] For example, the magnetic shielding member (30) may be formed in a circular loop shape. The cross-section of the magnetic shielding member (30) may be formed in a U-shape with a roughly flat bottom.

[0191] For example, a magnetic shielding member (30) may be placed on the second surface (11b) of the case (10). The magnetic shielding member (30) may be attached to the second surface (11b) of the case (10) with an adhesive member. A magnetic structure (20) may be placed inside the magnetic shielding member (30).

[0192] According to one embodiment, the magnetic shielding member (30) may include a first part (31), a second part (32), and a third part (33). Since the structure of the magnetic shielding member (30) is the same as that of the magnetic shielding member (30) shown in FIGS. 4 to 6, a redundant description is omitted.

[0193] The magnetic structure (20) may be placed in the magnetic shielding member (30). For example, at least a portion of the magnetic structure (20) may be accommodated in the magnetic shielding member (30). Thus, a first portion (31) of the magnetic shielding member (30) may cover the lower surface (20a) of the magnetic structure (20), a second portion (32) may cover the outer surface (20c) of the magnetic structure (20), and a third portion (33) may cover the inner surface (20d) of the magnetic structure (20). The upper surface (20b) of the magnetic structure (20) may be exposed to the outside without being covered by the magnetic shielding member (30).

[0194] According to one embodiment, the magnetic structure (20) may include a plurality of magnetic segments (e.g., magnetic segments (20S) of FIG. 4). The plurality of magnetic segments may be formed in an arc shape. The plurality of magnetic segments may be arranged in a circular loop shape.

[0195] According to one embodiment, a plurality of magnetic segments may be grouped into a first magnetic segment group (20S1), a second magnetic segment group (20S2), and a third magnetic segment group (20S3).

[0196] The first magnetic segment group (20S1) may be formed to provide an attractive force that is coupled to the external magnetic structure (203) of the external electronic device (200) (see FIG. 29). The first magnetic segment group (20S1) may be formed to have a first magnetic pole arrangement.

[0197] The first magnetic segment group (20S1) may include a plurality of first magnetic segment parts (20S11).

[0198] A plurality of first magnet segments (20S11) of a first magnet segment group (20S1) may include an inner magnet (22), a non-magnetic part (23), and an outer magnet (21). The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may each be formed in an arc shape. The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be formed in a rectangular cross-section.

[0199] The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be arranged concentrically. The non-magnetic part (23) may be placed on the outer surface of the inner magnet (22), and the outer magnet (21) may be placed on the outer surface of the non-magnetic part (23).

[0200] The inner magnet (22) and the outer magnet (21) can be formed of permanent magnets. The non-magnetic part (23) can be formed of a non-magnetic material.

[0201] For example, the first magnetic field arrangement may be such that the N pole of the outer magnet (21) is located below (e.g., in the -Z direction) and the S pole is located above (e.g., in the +Z direction), as shown in FIG. 5, and the S pole of the inner magnet (22) is located below (e.g., in the -Z direction) and the N pole is located above (e.g., in the +Z direction).

[0202] The second magnetic segment group (20S2) may be closer to the camera opening (12) than the first magnetic segment group (20S1). The second magnetic segment group (20S2) may be formed to have a second stimulation arrangement different from the first stimulation arrangement of the first magnetic segment group (20S1).

[0203] The second magnetic segment group (20S2) may include at least one second magnetic segment part (20S21).

[0204] The second magnet segment (20S21) of the second magnet segment group (20S2) may include an inner magnet (22), a non-magnetic part (23), and an outer magnet (21). The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may each be formed in an arc shape. The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be formed in a rectangular cross-section.

[0205] The inner magnet (22), the non-magnetic part (23), and the outer magnet (21) may be arranged concentrically. The non-magnetic part (23) may be placed on the outer surface of the inner magnet (22), and the outer magnet (21) may be placed on the outer surface of the non-magnetic part (23).

[0206] The inner magnet (22) and the outer magnet (21) can be formed of permanent magnets. The non-magnetic part (23) can be formed of a non-magnetic material.

[0207] The second magnetic field array may be formed differently from the first magnetic field array of the first magnetic field group (20S1) (e.g., the array of FIG. 5). For example, as shown in FIG. 10, the second magnetic field array may have the S pole of the outer magnet (21) located below (e.g., in the -Z direction) and the N pole located above (e.g., in the +Z direction), and the N pole of the inner magnet (22) located below (e.g., in the -Z direction) and the S pole located above (e.g., in the +Z direction). By making the second magnetic field array of the second magnetic field group (20S2) different from the first magnetic field array of the first magnetic field group (20S1), the magnetic force acting on the camera module (184) of the electronic device (101) located in the camera opening (12) of the case (10) can be reduced.

[0208] The third magnetic segment group (20S3) may be formed to have a third stimulation array. The third stimulation array may be formed to be detected by a Hall sensor (305) of the electronic device (101). The third magnetic segment group (20S3) may be formed as a sensing magnet (40). For example, the third stimulation array may be formed to have the same stimulation array as the sensing magnet (40) shown in FIG. 7.

[0209] According to one embodiment, the size or shape of one segment group among the first magnet segment group (20S1), the second magnet segment group (20S2), or the third magnet segment group (20S3) may be distinguishable from the other segment groups. For example, the length (arc length), thickness, or height of the segment groups may differ from one another. The first magnet segment group (20S1), the second magnet segment group (20S2), or the third magnet segment group (20S3) may include at least one magnet segment portion.

[0210] In the above description, the first magnetic segment (20S11) of the first magnetic segment group (20S1) of the magnetic structure (20) disposed inside the magnetic shielding member (30) is formed with a structure including an inner magnet (22), a non-magnetic part, and an outer magnet (21), but the structure of the first magnetic segment group (20S1) is not limited thereto. As shown in FIG. 11, the first magnetic segment (20S11) of the first magnetic segment group (20S1) may be formed to have a Halbach arrangement.

[0211] FIG. 11 is a partial cross-sectional view showing an apparatus according to one or more embodiments of the present disclosure.

[0212] Referring to FIG. 11, the first magnetic segment (20S11) of the first magnetic segment group (20S1) may be placed inside the magnetic shielding member (30). For example, the lower surface (20a) of the first magnetic segment (20S11) may be covered by the first part (31) of the magnetic shielding member (30), the outer surface (20c) of the first magnetic segment (20S11) may be covered by the second part (32) of the magnetic shielding member (30), and the inner surface (20d) of the first magnetic segment (20S11) may be covered by the third part (33) of the magnetic shielding member (30).

[0213] The first magnet segment (20S11) of the first magnet segment group (20S1) may include an inner magnet (22) and an outer magnet (21). According to one embodiment, the inner magnet (22) and the outer magnet (21) may be arranged in a Halbach arrangement. For example, the inner magnet (22) and the outer magnet (21) may be formed such that the magnetic direction of the inner magnet (22) and the magnetic direction of the outer magnet (21) are perpendicular to each other.

[0214] For example, the inner magnet (22) can be magnetized in a horizontal direction, and the outer magnet (21) can be magnetized in a vertical direction. As an example, the inner magnet (22) can be formed such that the N pole is located on the inside (e.g., +X direction) and the S pole is located on the outside (e.g., -X direction). The outer magnet (21) can be formed such that the N pole is located on the bottom (e.g., -Z direction) and the S pole is located on the top (e.g., +Z direction).

[0215] According to one embodiment, only one or more first magnetic segments (20S11) close to the camera opening (12) among the first magnetic segment group (20S1) are arranged in a Halbach arrangement, and the remaining first magnetic segments (20S11) can be arranged as shown in FIG. 5.

[0216] FIG. 12 is a partial view showing an apparatus according to one or more embodiments of the present disclosure. FIG. 13 is a partial cross-sectional view showing the apparatus of FIG. 12 according to one or more embodiments of the present disclosure, cut along line DD. FIG. 14 is a partial cross-sectional view showing the apparatus of FIG. 12 according to one or more embodiments of the present disclosure, cut along line EE.

[0217] Referring to FIGS. 12 to 14, an apparatus according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0218] The case (10) may be formed to be detachably coupled to the electronic device (101). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). Since the case (10) is identical to the case (10) of FIGS. 2 and FIGS. 3 described above, a redundant description is omitted.

[0219] The magnetic shielding member (30) can be formed to shield at least one portion of the magnetic force in at least one direction of the magnetic structure (20).

[0220] The magnetic shielding member (30) may be formed to surround the planar induction coil (303) (see FIG. 25) of the electronic device (101) when the case (10) is coupled to the electronic device (101). For example, the magnetic shielding member (30) may be formed in a loop shape that can surround the planar induction coil (303) of the electronic device (101).

[0221] For example, the magnetic shielding member (30) can be formed in a circular loop shape.

[0222] A magnetic shielding member (30) may be placed on the second side (11b) of the case (10). A magnetic structure (20) may be placed on the magnetic shielding member (30).

[0223] According to one embodiment, the magnetic shielding member (30) may include a first part (31), a second part (32), and a third part (33).

[0224] The first part (31) may be placed on the second surface (11b) of the case (10). The first part (31) may be formed to cover the lower surface (20a) of the magnetic structure (20). The first part (31) may be interposed between the second surface (11b) of the case (10) and the magnetic structure (20). Thus, when an electronic device (101) is coupled to the case (10), the first part (31) of the magnetic shielding member (30) may cover the lower surface (20a) of the magnetic structure (20) adjacent to the electronic device (101).

[0225] The second part (32) may be formed to cover the outer surface (20c) of the magnetic structure (20). The second part (32) may be extended from the outer end (31a) of the first part (31) and bent to cover the outer surface (20c) of the magnetic structure (20). The second part (32) may be provided to cover the outer surface (20c) of the part of the magnetic structure (20) facing the camera opening (12).

[0226] The remaining part of the magnetic structure (20) that is not adjacent to the camera opening (12) of the case (10) may not be covered by the second part (32) of the magnetic shielding member (30) as shown in FIG. 14.

[0227] The length (L) of the second part (32) can be determined to shield at least a portion of the magnetic force of the magnetic structure (20) that affects the camera module (184) of the electronic device (101) coupled to the camera opening (12) of the case (10). Accordingly, the second part (32) can limit at least a portion of the magnetic field in the direction of the camera opening (12) among the magnetic fields generated by the magnetic structure (20).

[0228] For example, the magnetic shielding member (30) may include a first section (S1) and a second section (S2). The first section (S1) may include a first section (31) in which a second section (32) is formed. The second section (S2) may include a first section (31) in which the second section (32) is not formed. In other words, the first section (S1) of the magnetic shielding member (30) may include a first section (31) and a second section (32). The second section (S2) may include the first section (31) and not include the second section (32).

[0229] The third part (33) may be formed to cover the inner surface (20d) of the magnetic structure (20). The third part (33) may be extended from the inner end (31b) of the first part (31) and bent to cover the inner surface (20d) of the magnetic structure (20). The third part (33) may be formed to cover the entire inner surface (20d) of the magnetic structure (20). According to one embodiment, the third part (33) may be formed to cover at least a portion of the inner surface (20d) of the magnetic structure (20). Thus, the third part (33) may limit at least a portion of the magnetic field in the direction of the planar induction coil (303) of the electronic device (101) among the magnetic fields generated by the magnetic structure (20).

[0230] The third part (33) may be arranged concentrically with the second part (32). The height of the third part (33) (e.g., h2 in FIG. 5) may be formed to be the same as the height of the second part (32) (e.g., h1 in FIG. 5).

[0231] For example, the first section (S1) of the magnetic shielding member (30) may include a first part (31), a second part (32), and a third part (33). The second section (S2) may include the first part (31) and the third part (33), and may not include the second part (32).

[0232] For example, the magnetic structure (20) may be placed on the magnetic shielding member (30). The upper surface (20b) of the magnetic structure (20) may be exposed to the outside without being covered by the magnetic shielding member (30).

[0233] According to one embodiment, the magnetic structure (20) may include a plurality of magnetic segments (20S). The plurality of magnetic segments (20S) may be formed in an arc shape. The plurality of magnetic segments (20S) may be arranged in a circular loop shape.

[0234] A plurality of magnetic segments (20S) may be formed to provide an attractive force that is coupled to an external magnetic structure (203) of an external electronic device (200) (see FIG. 29). A plurality of magnetic segments (20S) may be formed to have the same magnetic pole arrangement.

[0235] The magnetic structure (20) may include a sensing magnet (40). The sensing magnet (40) may be formed in a shape similar to the magnetic segment (20S). FIG. 12 is an embodiment in which the position of the sensing magnet (40) is different from FIG. 9.

[0236] Since the magnetic structure (20) is identical to the magnetic structure (20) according to the embodiment shown in FIGS. 4 to 7, a redundant description is omitted.

[0237] When the magnetic structure (20) includes a sensing magnet (40), the magnetic shielding member (30) may include an opening (34). One side of the magnetic structure (20) may be exposed through the opening (34) of the magnetic shielding member (30). The opening (34) may be formed at a position corresponding to the sensing magnet (40) of the magnetic structure (20). For example, the magnetic shielding member (30) may be formed as a circular loop in which parts of the first part (31) and the third part (33) are cut. Thus, the sensing magnet (40) may be exposed through the opening (34) of the magnetic shielding member (30). Then, since the magnetic field of the sensing magnet (40) is not blocked by the magnetic shielding member (30), the Hall sensor (305) of the electronic device (101) can detect the sensing magnet (40).

[0238] FIG. 15 is a partial view showing an apparatus according to one or more embodiments of the present disclosure. FIG. 16 is a partial cross-sectional view showing the apparatus of FIG. 15 according to one or more embodiments of the present disclosure by cutting along line FF.

[0239] Referring to FIGS. 15 and 16, an apparatus according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0240] The case (10) may be formed to be detachably coupled to the electronic device (101). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). Since the case (10) is identical to the case (10) of FIGS. 2 and FIGS. 3 described above, a redundant description is omitted.

[0241] The magnetic shielding member (30) can be formed to shield at least a portion of the magnetic force in at least one direction of the magnetic structure (20).

[0242] The magnetic shielding member (30) may be formed to surround the planar induction coil (303) (see FIG. 25) of the electronic device (101) when the case (10) is coupled to the electronic device (101). For example, the magnetic shielding member (30) may be formed as a circular loop that can surround the planar induction coil (303) of the electronic device (101).

[0243] A magnetic shielding member (30) may be placed on the second side (11b) of the case (10). A magnetic structure (20) may be placed on the magnetic shielding member (30).

[0244] According to one embodiment, the magnetic shielding member (30) may include a first part (31) and a second part (32).

[0245] The first part (31) may be placed on the second surface (11b) of the case (10). The first part (31) may be formed to cover the lower surface (20a) of the magnetic structure (20). The first part (31) may be interposed between the second surface (11b) of the case (10) and the magnetic structure (20). Thus, when an electronic device (101) is coupled to the case (10), the first part (31) of the magnetic shielding member (30) may cover the lower surface (20a) of the magnetic structure (20) adjacent to the electronic device (101).

[0246] The second part (32) may be formed to cover the outer surface (20c) of the magnetic structure (20). The second part (32) may be extended from the outer end (31a) of the first part (31) and bent to cover the outer surface (20c) of the magnetic structure (20). The second part (32) may be provided to cover the outer surface (20c) of the part of the magnetic structure (20) facing the camera opening (12).

[0247] The outer surface (20c) of the remaining part of the magnetic structure (20) that is not adjacent to the camera opening (12) of the case (10) may not be covered by the second part (32).

[0248] The length (L) of the second part (32) can be determined to shield at least a portion of the magnetic force of the magnetic structure (20) that affects the camera module (184) of the electronic device (101) coupled to the camera opening (12) of the case (10). Accordingly, the second part (32) can limit at least a portion of the magnetic field in the direction of the camera opening (12) among the magnetic fields generated by the magnetic structure (20).

[0249] For example, the magnetic shielding member (30) may include a first section (S1) and a second section (S2). The first section (S1) may include a first section (31) in which a second section (32) is formed. The second section (S2) may include a first section (31) in which the second section (32) is not formed. In other words, the first section (S1) of the magnetic shielding member (30) may include a first section (31) and a second section (32). The second section (S2) may include the first section (31) and not include the second section (32).

[0250] The magnetic shielding member (30) shown in FIGS. 15 and 16 may not include a third part (33) formed at the inner end of the first part (31), unlike the magnetic shielding member (30) shown in FIGS. 12 to 14.

[0251] For example, the magnetic structure (20) may be placed on the magnetic shielding member (30). The upper surface (20b) of the magnetic structure (20) may be exposed to the outside without being covered by the magnetic shielding member (30).

[0252] Since the magnetic structure (20) is identical to the magnetic structure (20) according to the embodiment shown in FIGS. 4 to 7, a redundant description is omitted. FIG. 15 is an embodiment in which the position of the sensing magnet (40) is different from FIG. 9.

[0253] When the magnetic structure (20) includes a sensing magnet (40), the magnetic shielding member (30) may include an opening (34). One side of the magnetic structure (20) may be exposed through the opening (34) of the magnetic shielding member (30). The opening (34) may be formed at a position corresponding to the sensing magnet (40) of the magnetic structure (20). For example, the magnetic shielding member (30) may be formed as a circular loop in which a portion of the first part (31) is cut. Thus, the sensing magnet (40) may be exposed through the opening (34) of the magnetic shielding member (30). Then, since the magnetic field of the sensing magnet (40) is not blocked by the magnetic shielding member (30), the Hall sensor (305) of the electronic device (101) can detect the sensing magnet (40).

[0254] Although the above description describes a device (1) in which a magnetic structure (20) and a magnetic shielding member (30) are disposed on the outside of a case (10), that is, on the second surface (11b) of the case (10), the device (1) according to one or more embodiments of the present disclosure is not limited thereto. As shown in FIGS. 17 and 18, the magnetic structure (20) and the magnetic shielding member (30) may be disposed on the other surface of the case (10).

[0255] FIG. 17 is a perspective view showing an apparatus according to one or more embodiments of the present disclosure. FIG. 18 is a partial cross-sectional view showing the apparatus of FIG. 17 according to one or more embodiments of the present disclosure by cutting along line GG.

[0256] Referring to FIGS. 17 and 18, an apparatus (1) according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0257] The case (10) may be formed to be detachably coupled to the electronic device (101). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). When the case (10) is coupled to the electronic device (101), the camera module (184) of the electronic device (101) may be positioned in the camera opening (12) of the case (10). Since the case (10) is identical to the case (10) of FIGS. 2 and FIGS. 3 described above, a redundant description is omitted.

[0258] The magnetic structure (20) may be formed to surround the planar induction coil (303) of the electronic device (101) when the case (10) is coupled to the electronic device (101). For example, the magnetic structure (20) may be formed as a circular loop that can surround the planar induction coil (303) of the electronic device (101).

[0259] The magnetic structure (20) can be placed on the first surface (11a) of the case (10). The lower surface (20a) of the magnetic structure (20) can be attached to the first surface (11a) of the case (10) with an adhesive member (e.g., the adhesive member (35) of FIG. 6).

[0260] According to one embodiment, the magnetic structure (20) may include a plurality of magnetic segments (20S). The plurality of magnetic segments (20S) may be formed in an arc shape. The plurality of magnetic segments (20S) may be arranged in a circular loop shape.

[0261] A plurality of magnetic segments (20S) can be formed to provide an attractive force that is coupled to an external magnetic structure (203) of an external electronic device (200) (see FIG. 29).

[0262] Each of the plurality of magnetic segments (20S) may include an inner magnet (22), a non-magnetic part (23), and an outer magnet (21). A non-magnetic part (23) may be disposed on the outer surface of the inner magnet (22), and an outer magnet (21) may be disposed on the outer surface of the non-magnetic part (23).

[0263] According to one embodiment, the inner magnet (22) and the outer magnet (21) may be magnetized in a vertical direction. The magnetic direction of the inner magnet (22) may be opposite to the magnetic direction of the outer magnet (21). For example, the outer magnet (21) may be positioned so that the N pole is located at the top (e.g., -Z direction) and the S pole is located at the bottom (e.g., +Z direction). The inner magnet (22) may be positioned so that the N pole is located at the bottom (e.g., +Z direction) and the S pole is located at the top (e.g., -Z direction).

[0264] In addition, since the plurality of magnetic segments (20S) can be formed identically to the plurality of magnetic segments (20S) of the device according to the above-described embodiment, a redundant description is omitted.

[0265] The magnetic structure (20) may include a sensing magnet (40). The sensing magnet (40) may be formed in a shape similar to the magnetic segment (20S). FIG. 17 is an embodiment in which the position of the sensing magnet (40) is different from FIG. 9. Since the sensing magnet (40) is identical to the sensing magnet (40) of the device according to the above-described embodiment, a redundant description is omitted.

[0266] The magnetic shielding member (30) can be formed to shield at least a portion of the magnetic force in at least one direction of the magnetic structure (20).

[0267] The magnetic shielding member (30) can be placed on the upper surface (20b) of the magnetic structure (20). The magnetic shielding member (30) can be placed to cover the magnetic structure (20). The magnetic shielding member (30) can be attached to the upper surface (20b) of the magnetic structure (20) with an adhesive member. Thus, the magnetic structure (20) can be placed inside the magnetic shielding member (30).

[0268] According to one embodiment, the magnetic shielding member (30) may include a first part (31), a second part (32), and a third part (33).

[0269] The first part (31) may be formed to cover the upper surface (20b) of the magnetic structure (20). The magnetic structure (20) may be interposed between the first surface (11a) of the case (10) and the first part (31) of the magnetic shielding member (30). Thus, when the electronic device (101) is coupled to the case (10), the first part (31) of the magnetic shielding member (30) may be adjacent to or in contact with the electronic device (101).

[0270] The second part (32) may be formed to cover the outer surface (20c) of the magnetic structure (20). The second part (32) may be extended from the outer end (31a) of the first part (31) and bent to cover the outer surface (20c) of the magnetic structure (20). The second part (32) may be formed to cover at least a portion of the outer surface (20c) of the magnetic structure (20). The second part (32) may be arranged to face the camera opening (12). Thus, the second part (32) may limit at least a portion of the magnetic field in the direction of the camera opening (12) among the magnetic fields generated by the magnetic structure (20).

[0271] The third part (33) may be formed to cover the inner surface (20d) of the magnetic structure (20). The third part (33) may be extended from the inner end (31b) of the first part (31) and bent to cover the inner surface (20d) of the magnetic structure (20). The third part (33) may be formed to cover the entire inner surface (20d) of the magnetic structure (20). Thus, the third part (33) may limit at least a portion of the magnetic field in the direction of the planar induction coil (303) of the electronic device (101) among the magnetic fields generated by the magnetic structure (20).

[0272] The third part (33) can be arranged concentrically with the second part (32). The height (h2) of the third part (33) can be formed to be the same as the height (h1) of the second part (32).

[0273] In addition, since the magnetic shielding member (30) can be formed in the same way as the magnetic shielding member (30) of the device according to the above-described embodiment, a redundant description is omitted.

[0274] In the above description, the magnetic structure (20) is formed with a structure including an inner magnet (22), a non-magnetic part (23), and an outer magnet (21), but the structure of the magnetic structure (20) is not limited thereto. As shown in FIGS. 19 and FIGS. 20, the magnetic structure (20) may be formed to have a Halbach arrangement.

[0275] FIG. 19 is a drawing showing an apparatus according to one or more embodiments of the present disclosure. FIG. 20 is a partial cross-sectional view showing the apparatus of FIG. 19 according to one or more embodiments of the present disclosure by cutting along line HH.

[0276] Referring to FIGS. 19 and 20, an apparatus according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0277] The case (10) may be formed to be detachably coupled to the electronic device (101). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). When the case (10) is coupled to the electronic device (101), the camera module (184) of the electronic device (101) may be located in the camera opening (12) of the case (10). Since the case (10) is identical to the case (10) of FIGS. 2 and FIGS. 3 described above, a redundant description is omitted.

[0278] The magnetic shielding member (30) can be formed to shield at least a portion of the magnetic force in at least one direction of the magnetic structure (20).

[0279] The magnetic shielding member (30) may be formed to surround the planar induction coil (303) of the electronic device (101) when the case (10) is coupled to the electronic device (101). For example, the magnetic shielding member (30) may be formed as a circular loop that can surround the planar induction coil (303) of the electronic device (101).

[0280] A magnetic shielding member (30) may be placed on the second side (11b) of the case (10). A magnetic structure (20) may be placed on the magnetic shielding member (30).

[0281] According to one embodiment, the magnetic shielding member (30) may be formed to cover the lower surface (20a) of the magnetic structure (20). The magnetic shielding member (30) may be interposed between the second surface (11b) of the case (10) and the magnetic structure (20). Thus, when an electronic device (101) is coupled to the case (10), the magnetic shielding member (30) may cover the lower surface (20a) of the magnetic structure (20) adjacent to the electronic device (101).

[0282] The magnetic shielding member (30) shown in FIGS. 19 and 20 may not include a second part (32) and a third part (33) covering the outer surface (20c) and inner surface (20d) of the magnetic structure (20), unlike the magnetic shielding member (30) of the device according to the above-described embodiment.

[0283] The magnetic structure (20) can be placed on the magnetic shielding member (30). For example, the magnetic structure (20) can be fixed to the upper surface (e.g., +Z direction) of the magnetic shielding member (30). The upper surface (20b) and both sides (20c, 20d) of the magnetic structure (20) can be exposed to the outside without being covered by the magnetic shielding member (30).

[0284] According to one embodiment, the magnetic structure (20) may include a plurality of magnetic segments (20S). The plurality of magnetic segments (20S) may be formed in an arc shape. The plurality of magnetic segments (20S) may be arranged in a circular loop shape.

[0285] A plurality of magnetic segments (20S) can be formed to provide an attractive force that is coupled with an external magnetic structure (203) of an external electronic device (200).

[0286] Each of the plurality of magnetic segments (20S) can be formed as a Halbach array. Forming the plurality of magnetic segments (20S) as a Halbach array can reduce the magnetic field emitted by the magnetic structure (20) in the horizontal direction.

[0287] According to one embodiment, the magnetic segment (20S) may include an inner magnet (22) and an outer magnet (21). The inner magnet (22) and the outer magnet (21) may be arranged in a Halbach arrangement. For example, the inner magnet (22) and the outer magnet (21) may be formed such that the magnetic direction of the inner magnet (22) and the magnetic direction of the outer magnet (21) are perpendicular. For example, the inner magnet (22) may be magnetized in a horizontal direction, and the outer magnet (21) may be magnetized in a vertical direction. As an example, the inner magnet (22) may be formed such that the N pole is located on the inner side (e.g., +X direction) and the S pole is located on the outer side (e.g., -X direction). The outer magnet (21) may be formed such that the N pole is located on the lower side (e.g., -Z direction) and the S pole is located on the upper side (e.g., +Z direction).

[0288] According to one embodiment, the magnetic segment (20S) may be formed such that the width (W1) of the outer magnet (21) and the width (W2) of the inner magnet (22) are in a 1:2 ratio. By forming the outer magnet (21) and the inner magnet (22) of the magnetic segment (20S) in this way, the influence of the magnetic field applied to the camera module (184) of the electronic device (101) adjacent to the outer magnet (21) can be reduced.

[0289] The magnetic structure (20) may include a sensing magnet (40). The sensing magnet (40) may be formed in a shape similar to the magnetic segment (20S). Since the sensing magnet (40) is identical to the sensing magnet (40) of the device according to the above-described embodiment, a redundant description is omitted.

[0290] FIG. 21 is a partial view showing an apparatus according to one or more embodiments of the present disclosure. FIG. 22 is a partial cross-sectional view showing the apparatus of FIG. 21 according to one or more embodiments of the present disclosure, cut along line II.

[0291] Referring to FIGS. 21 and 22, an apparatus (1) according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0292] The case (10) may be formed to be detachably coupled to the electronic device (101). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). When the case (10) is coupled to the electronic device (101), the camera module (184) of the electronic device (101) may be located in the camera opening (12) of the case (10). Since the case (10) is identical to the case (10) of FIGS. 2 and FIGS. 3 described above, a redundant description is omitted.

[0293] The magnetic shielding member (30) can be formed to shield at least a portion of the magnetic force in at least one direction of the magnetic structure (20).

[0294] The magnetic shielding member (30) may be formed to surround the planar induction coil (303) of the electronic device (101) when the case (10) is coupled to the electronic device (101). For example, the magnetic shielding member (30) may be formed as a circular loop that can surround the planar induction coil (303) of the electronic device (101).

[0295] A magnetic shielding member (30) may be placed on the second side (11b) of the case (10). A magnetic structure (20) may be placed on the upper surface (e.g., +Z direction) of the magnetic shielding member (30).

[0296] According to one embodiment, the magnetic shielding member (30) may be formed to cover the lower surface (20a) of the magnetic structure (20). The magnetic shielding member (30) may be interposed between the second surface (11b) of the case (10) and the magnetic structure (20). Thus, when an electronic device (101) is coupled to the case (10), the magnetic shielding member (30) may cover the lower surface (20a) of the magnetic structure (20) adjacent to the electronic device (101).

[0297] The magnetic shielding member (30) shown in FIGS. 21 and 22 may not include a second part (32) and a third part (33) covering the outer surface (20c) and inner surface (20d) of the magnetic structure (20), unlike the magnetic shielding member (30) of the device according to the above-described embodiment.

[0298] The magnetic structure (20) can be placed on the magnetic shielding member (30). For example, the magnetic structure (20) can be fixed to the upper surface (e.g., +Z direction) of the magnetic shielding member (30). The upper surface (20b) and both sides (20c, 20d) of the magnetic structure (20) can be exposed to the outside without being covered by the magnetic shielding member (30).

[0299] According to one embodiment, the magnetic structure (20) may include a plurality of magnetic segments (20S). The plurality of magnetic segments (20S) may be formed in an arc shape. The plurality of magnetic segments (20S) may be arranged in a circular loop shape.

[0300] A plurality of magnetic segments (20S) can be formed to provide an attractive force that is coupled with an external magnetic structure (203) of an external electronic device (200).

[0301] Each of the plurality of magnetic segments (20S) can be formed as a Halbach array. Forming the plurality of magnetic segments (20S) as a Halbach array can reduce the magnetic field emitted by the magnetic structure (20) in the horizontal direction.

[0302] According to one embodiment, the magnetic segment (20S) may include an inner magnet (22) and an outer magnet (21). The inner magnet (22) and the outer magnet (21) may be arranged in a Halbach arrangement. For example, the inner magnet (22) and the outer magnet (21) may be formed such that the magnetic direction of the inner magnet (22) and the magnetic direction of the outer magnet (21) are perpendicular. For example, the inner magnet (22) may be magnetized in a vertical direction, and the outer magnet (21) may be magnetized in a horizontal direction. As an example, the inner magnet (22) may be formed such that the N pole is located at the top (e.g., +Z direction) and the S pole is located at the bottom (e.g., -Z direction). The outer magnet (21) may be formed such that the N pole is located at the inside (e.g., +X direction) and the S pole is located at the outside (e.g., -X direction).

[0303] According to one embodiment, the magnetic segment (20S) can be formed such that the width (W1) of the outer magnet (21) and the width (W2) of the inner magnet (22) are in a 2:1 ratio. By forming the outer magnet (21) and the inner magnet (22) of the plurality of magnetic segments (20S) in this way, the influence of the magnetic field applied to the planar induction coil (303) of the electronic device (101) located inside the magnetic structure (20), for example, a wireless charging antenna and / or an MST (magnetic secure transmission) antenna, can be reduced.

[0304] The magnetic structure (20) may include a sensing magnet (40). The sensing magnet (40) may be formed in a shape similar to the magnetic segment (20S). FIG. 21 is an embodiment in which the position of the sensing magnet (20) is different from FIG. 9. Since the sensing magnet (40) is identical to the sensing magnet (40) of the device according to the above-described embodiment, a redundant description is omitted.

[0305] FIG. 23 is a partial view showing an apparatus according to one or more embodiments of the present disclosure.

[0306] Referring to FIG. 23, an apparatus according to one or more embodiments of the present disclosure may include a case (10), a magnetic structure (20), and a magnetic shielding member (30).

[0307] The case (10) may be formed to be detachably coupled to the electronic device (101). The case (10) may be formed to accommodate the electronic device (101) in a shape corresponding to the electronic device (101). Since the case (10) is identical to the case (10) of FIGS. 2 and FIGS. 3 described above, a redundant description is omitted.

[0308] Since the magnetic shielding member (30) is identical to the magnetic shielding member (30) of the device shown in FIG. 21 and FIG. 22 described above, a redundant description is omitted.

[0309] The magnetic structure (20) can be placed on the magnetic shielding member (30). For example, the magnetic structure (20) can be fixed to the upper surface (e.g., +Z direction) of the magnetic shielding member (30). The upper surface and both sides of the magnetic structure (20) can be exposed to the outside without being covered by the magnetic shielding member (30) (see FIG. 22).

[0310] According to one embodiment, the magnetic structure (20) may include a plurality of magnetic segments. The plurality of magnetic segments may be formed in an arc shape. The plurality of magnetic segments may be arranged in a circular loop shape.

[0311] A plurality of magnetic segments can be formed to provide an attractive force that is coupled with an external magnetic structure (203) of an external electronic device (200).

[0312] According to one embodiment, a plurality of magnetic segments can be grouped into a first magnetic segment group (20S1), a second magnetic segment group (20S2), and a third magnetic segment group (20S3).

[0313] The first magnetic segment group (20S1) may be formed to provide an attractive force that is coupled to the external magnetic structure (203) of the external electronic device (200). The first magnetic segment group (20S1) may be formed to have a first magnetic pole arrangement.

[0314] The first magnet segment group (20S1) may include a plurality of first magnet segment parts (20S11). In the case of the embodiment illustrated in FIG. 23, the first magnet segment group (20S1) may include 13 first magnet segment parts (20S11).

[0315] A plurality of first magnet segments (20S11) of the first magnet segment group (20S1) may be formed in a Halbach arrangement. According to one embodiment, the first magnet segment (20S11) may include an inner magnet (22) and an outer magnet (21). The inner magnet (22) and the outer magnet (21) may be arranged in a Halbach arrangement. For example, the inner magnet (22) and the outer magnet (21) may be formed such that the magnetic direction of the inner magnet (22) and the magnetic direction of the outer magnet (21) are perpendicular to each other.

[0316] As an example, the inner magnet (22) and the outer magnet (21) of the first magnet segment (20S11) can be formed as shown in FIG. 22. For example, the first magnet segment (20S11) can be formed such that the width (W1) of the outer magnet (21) and the width (W2) of the inner magnet (22) are in a 2:1 ratio.

[0317] The second magnetic segment group (20S2) may be closer to the camera opening (12) than the first magnetic segment group (20S1). The second magnetic segment group (20S2) may be formed to have a second stimulation arrangement different from the first stimulation arrangement of the first magnetic segment group (20S1).

[0318] The second magnet segment group (20S2) may include at least one second magnet segment part (20S21). In the case of the embodiment illustrated in FIG. 23, the second magnet segment group (20S2) may include two second magnet segment parts (20S21).

[0319] The second magnet segment (20S21) of the second magnet segment group (20S2) may be formed in a Halbach arrangement. According to one embodiment, the second magnet segment (20S21) may include an inner magnet (22) and an outer magnet (21). The inner magnet (22) and the outer magnet (21) may be arranged in a Halbach arrangement.

[0320] The second magnetic field may be formed differently from the first magnetic field of the first magnetic field section (20S11). For example, the inner magnetic field (22) and the outer magnetic field (21) may be formed such that the magnetic field direction of the inner magnetic field (22) and the magnetic field direction of the outer magnetic field (21) are perpendicular. As an example, the inner magnetic field (22) and the outer magnetic field (21) of the second magnetic field section (20S21) may be formed as shown in FIG. 20. For example, the second magnetic field section (20S21) may be formed such that the width (W1) of the outer magnetic field (21) and the width (W2) of the inner magnetic field (22) are in a 1:2 ratio.

[0321] If the second magnetic field arrangement of the second magnetic field group (20S2) is different from the first magnetic field arrangement of the first magnetic field group (20S1), the effect of the magnetic field acting on the camera module (184) of the electronic device (101) located at the camera opening (12) of the case (10) can be reduced.

[0322] In the case of the embodiment illustrated in FIG. 23, the second magnet segment group (20S2) may include two second magnet segment parts (20S21).

[0323] The third magnetic segment group (20S3) may be formed to have a third magnetic array. The third magnetic segment group (20S3) may include one third magnetic segment. The third magnetic array may be formed to be detected by a Hall sensor (305) of the electronic device (101). For example, the third magnetic array may be formed to have the same magnetic array as the sensing magnet (40) shown in FIG. 7. In other words, the third magnetic segment (20S3) may be formed as the sensing magnet (40) of the device (1) according to the above-described embodiment.

[0324] According to one embodiment, the first magnetic segment group (20S1), the second magnetic segment group (20S2), and the third magnetic segment group (20S3) of the magnetic structure (20) can all provide an attractive force that can be attached to the external magnetic structure (203), but the second magnetic segment group (20S2) and the third magnetic segment group (20S3) can provide less attractive force than the first magnetic segment group (20S1).

[0370] Hereinafter, with reference to FIG. 32, a system for wirelessly charging a battery (171) of an electronic device (101) including a device (1) according to one or more embodiments of the present disclosure will be described.

[0371] FIG. 32 is a drawing showing a wireless charging system for charging an electronic device combined with a device according to one or more embodiments of the present disclosure.

[0372] Referring to FIG. 32, a wireless charging system according to one or more embodiments of the present disclosure may include an electronic device (101) and a charging station (200).

[0373] The electronic device (101) and the charging station (200) can be coupled and aligned with each other at a distance of less than a certain distance to wirelessly transmit and receive power. For example, power can be transmitted and received through magnetic coupling between induction coils placed in the electronic device (101) and the charging station (200). For example, a magnetic field can be formed in an induction coil (201) formed by at least one wire wound concentrically in a plane, thereby charging the battery (171) equipped in the electronic device (101). According to one embodiment, in addition to the magnetic induction method, a magnetic resonance method may be used. An antenna (e.g., an induction coil) for transmitting and receiving power between the electronic device (101) and the charging station (200) can be aligned with each other using magnetic force or a mechanical coupling structure.

[0375] The charging station (200) may be configured to wirelessly charge the battery (171) of the electronic device (101). The charging station (200) may be a counterpart device or an external electronic device. The charging station (200) may be wired to a commercial power source (e.g., outlet) (210) to receive power for charging the electronic device (101). Alternatively, the charging station (200) may be wirelessly or wired connected to another external electronic device (102) (e.g., personal computer (PC), laptop, mass storage device). The charging station (200) may receive power for charging wirelessly or wired from another external electronic device (102). The charging station (200) may receive power for charging from the commercial power source (210) and may transmit / receive data by connecting to the memory of the other external electronic device (102). A separate antenna for data communication may be positioned in close proximity to an induction coil in the electronic device (101) and the charging station (200). The charging station (200) can communicate data without another device through the memory and processor included within the charging station (200). The charging station (200) described above and another external electronic device (102) (e.g., a PC) may be a single device.

[0376] The electronic device (101) and the charging station (200) may each include a magnetic structure (20, 203) (magnetic structure, magnetic array, or magnetic ring) formed to provide a certain attractive force.

[0377] The magnetic structure (20) of the electronic device (101) can be formed in a loop shape that wraps around the outer edge of the induction coil (303) of the electronic device (101). The magnetic structure (203) of the charging station (200) can be formed in a loop shape that wraps around the outer edge of the induction coil (201) of the charging station (200). When the magnetic structure (20) of the electronic device (101) is magnetically coupled and aligned with the magnetic structure (203) of the charging station (200), the induction coil (303) of the electronic device (101) and the induction coil (201) of the charging station (200) can be aligned with each other.

[0378] The electronic device (101) may include a magnetic shielding member (30) positioned to cover at least a portion of the magnetic structure (20). According to one embodiment, the magnetic structure (20) and the magnetic shielding member (30) may be positioned on an accessory cover (1) that is detachably coupled to the electronic device (101).

[0379] Accordingly, when a device (1) according to one or more embodiments of the present disclosure, i.e., an electronic device (101) with an accessory cover attached, is positioned on the upper surface of a charging station (200), the magnetic structure (20) of the accessory cover (1) and the magnetic structure (203) of the charging station (200) can be coupled by magnetic force. The battery (171) of the electronic device (101) can be wirelessly charged by the induction coil (303) of the electronic device (101) and the induction coil (201) of the charging station (200).

[0380] Hereinafter, a method for a processor (130) (see FIG. 1) of an electronic device (101) according to one or more embodiments of the present disclosure to recognize an accessory cover (1) having a magnetic structure (20) and control the electronic device (101) will be described in detail with reference to FIGs. 33 to 35.

[0381] FIG. 33 is a flowchart illustrating a method for an electronic device according to one or more embodiments of the present disclosure to recognize an accessory cover and a charging station. In FIG. 33, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0382] In operation 3001, the processor (130) of the electronic device (101) can read the Hall sensor (305). For example, the processor (130) can recognize the read value of the Hall sensor (305) through an electrical signal transmitted from the Hall sensor (305). Here, the read value of the Hall sensor (305) may be the magnitude of the magnetic force detected by the Hall sensor (305).

[0383] In operation 3002, the processor (130) can check whether the value read by the Hall sensor (305) is greater than the cover mounting reference value. Here, the cover mounting reference value may be the magnitude of the electrical signal output by the Hall sensor (305) when the Hall sensor (305) detects the sensing magnet (40) placed on the accessory cover (1).

[0384] If the read value of the Hall sensor (305) is smaller than the cover mounting reference value (operation 3002-N), the processor (130) can read the Hall sensor (305) in operation 3001.

[0385] If the value read by the Hall sensor (305) is greater than the cover mounting reference value (operation 3002-Y), in operation 3003, the processor (130) can recognize that the accessory cover (1) is mounted on the electronic device (101).

[0386] In operation 3004, the processor (130) can read the Hall sensor (305).

[0387] In operation 3005, the processor (130) can check whether the value read by the Hall sensor (305) is smaller than the cover removal threshold value. Here, the cover removal threshold value may be the magnitude of the electrical signal output by the Hall sensor (305) of the electronic device (101) when the accessory cover (1) is removed from the electronic device (101).

[0388] If the value read by the Hall sensor (305) is smaller than the cover removal reference value (operation 3005-Y), in operation 3000, the processor (130) can recognize that the accessory cover (1) has been removed or separated from the electronic device (101).

[0389] If the value read by the Hall sensor (305) is greater than or equal to the cover removal reference value (operation 3005-N), in operation 3006, the processor (130) can check whether the value read by the Hall sensor (305) is greater than the charging station recognition reference value. Here, the charging station recognition reference value may be the magnitude of the electrical signal output by the Hall sensor (305) when the Hall sensor (305) detects the magnetic structure (203) of the charging station (200). For example, the charging station recognition reference value may be greater than the cover mounting reference value.

[0390] If the read value of the Hall sensor (305) is less than or equal to the charging station recognition reference value (operation 3006-N), in operation 3004, the processor (130) can read the Hall sensor (305) again.

[0391] If the value read by the Hall sensor (305) is greater than the charging station recognition reference value (operation 3006-Y), in operation 3007, the processor (130) recognizes that the electronic device (101) equipped with the accessory cover (1) is located at the charging station (200) and can maintain wireless charging. For example, the electronic device (101) can perform operations to perform wireless charging with the charging station (200).

[0392] In operation 3008, the processor (130) can determine whether the reading of the Hall sensor (305) is smaller than the charging station removal threshold value. If the reading of the Hall sensor (305) is greater than or equal to the charging station removal threshold value (operation 3008-N), in operation 3007, the processor (130) can recognize that the electronic device (101) equipped with the accessory cover (1) is positioned at the charging station (200) and can maintain wireless charging.

[0393] If the value read by the Hall sensor (305) is less than the charging station removal threshold value (operation 3008-Y), in operation 3009, the processor (130) can turn off wireless charging. Additionally, in operation 3009, the processor (130) can recognize that the charging station (200) has been removed and maintain the recognition that the accessory cover (1) is attached.

[0394] In operation 3010, the processor (130) reads the Hall sensor (305) and can check whether the read value of the Hall sensor (305) is smaller than the cover removal reference value.

[0395] If the read value of the Hall sensor (305) is smaller than the cover removal reference value (operation 3010-Y), in operation 3000, the processor (130) can recognize that the accessory cover (1) has been removed or separated from the electronic device (101). In operation 3001, the processor (130) can read the Hall sensor (305) again.

[0396] If the read value of the Hall sensor (305) is equal to or greater than the cover removal reference value (operation 3010-N), in operation 3004, the processor (130) can read the Hall sensor (305) again.

[0397] An electronic device (101) according to one or more embodiments of the present disclosure may include a Hall sensor (305) formed to recognize a magnetic structure (20) of an accessory cover (1), a memory (120) for storing instructions, and at least one processor (130).

[0398] At least one processor (130) can control at least one of the camera module (184) or the display module differently from when the accessory cover (1) is not attached when it recognizes through the Hall sensor (305) that the accessory cover (1) is attached while executing instructions individually or collectively.

[0399] Hereinafter, with reference to FIG. 34, a method for optimizing the performance of an electronic device (101) is described when the processor (130) of an electronic device (101) according to one or more embodiments of the present disclosure recognizes an accessory cover (1).

[0400] FIG. 34 is a flowchart illustrating a method for optimizing performance when an electronic device according to one or more embodiments of the present disclosure recognizes an accessory cover. In FIG. 34, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0401] Referring to FIG. 34, in operation 3011, the processor (130) can recognize the accessory cover (1). In operation 3012, when the processor (130) recognizes the accessory cover (1), it can set MPP wireless charging as a priority. For example, after the processor (130) recognizes the accessory cover (1), it can set MPP as a priority among the wireless charging protocols supported by the electronic device (101), such as BPP (basic power protocol), EPP (extended power protocol), and / or MPP (magnetic power protocol).

[0402] In one embodiment, the processor (130) can check in operation 3013 whether Samsung Pay is running while the accessory cover (1) is attached to the electronic device (101). If Samsung Pay is running while the accessory cover (1) is attached to the electronic device (101) (operation 3013-Y), that is, if the MST (magnetic secure transmission) antenna is activated, the processor (130) can update the MST power in operation 3014. Alternatively, the processor (130) can update the MST power at the time when the accessory cover (1) is attached to the electronic device (101). As an example, if the MST antenna is activated, the processor (130) can set the PCR (peak current regulation) current value of the MST power high. The PCR current value can be set to the maximum considering the recognition compatibility of the POS (point of sale) device that recognizes Samsung Pay. Additionally, the processor (130) can adjust the voltage value of the MST power.

[0403] In one embodiment, the processor (130) can check in operation 3015 whether the digitizer is running while the accessory cover (1) is attached to the electronic device (101). The digitizer may be an example of a stylus pen that can input commands to the electronic device (101) by touching or hovering on the screen. If the digitizer is running while the accessory cover (1) is attached to the electronic device (101) (operation 3015-Y), the processor (130) can update the digitizer recognition software (SW) in operation 3016 to increase the recognition rate of the digitizer. Alternatively, the processor (130) can update the digitizer recognition software at the time the accessory cover (1) is attached to the electronic device (101). For example, when an accessory cover (1) is attached to an electronic device (101), the permeability of the ferrite core inside the digitizer can be lowered by the magnetic structure (20) of the accessory cover (1). When the permeability of the ferrite core of the digitizer is lowered, the inductor value of the ferrite coil can be changed. When the inductor value of the ferrite coil is changed, the LC resonant frequency is changed, and the processor (130) may not be able to recognize the digitizer. When an accessory cover (1) is attached to an electronic device (101), the LC resonant frequency can be adjusted by updating the digitizer recognition software so that the processor (130) can recognize the digitizer.

[0404] In one embodiment, the processor (130) can check in operation 3017 whether the camera module (184) is executed while the accessory cover (1) is attached to the electronic device (101). If the camera module (184) is executed while the accessory cover (1) is attached to the electronic device (101) (operation 3017-Y), in operation 3018, the processor (130) can update the optical image stabilization (OIS) of the camera module (184) so ​​that it operates properly. Alternatively, the processor (130) can update the OIS at the time when the accessory cover (1) is attached to the electronic device (101). When the accessory cover (1) is attached to the electronic device (101), the OIS may be affected by the magnetic structure (20) of the accessory cover (1). As an example, when the accessory cover (1) is attached to the electronic device (101), vibration may occur due to the magnetic structure (20). Then, the gyroscope sensor can detect the amount of shaking and transmit it to the OIS MCU (micro control unit). The OIS MCU can transmit a target signal to the driver IC to move the lens or sensor in the direction opposite to the shaking. The driver IC can correct the OIS by transmitting a signal to the driver of the camera module (184) based on the target signal to move the lens or image sensor.

[0405] In one embodiment, in operation 3011, when the processor (130) recognizes the accessory cover (1), it may output a user interface indicating that some errors may occur in the MST, NFC, stylus pen, camera, and / or antenna related functions.

[0406] Hereinafter, with reference to FIG. 35, a method for optimizing the performance of an electronic device (101) is described when the processor (130) of an electronic device (101) according to one or more embodiments of the present disclosure recognizes an accessory cover (1) and a charging station (200).

[0407] FIG. 35 is a flowchart illustrating a method for optimizing performance when an electronic device according to one or more embodiments of the present disclosure recognizes an accessory cover and a charging station. In FIG. 35, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0408] When the processor (130) of the electronic device (101) according to one or more embodiments of the present disclosure recognizes the accessory cover (1) and the charging station (200) in operation 3020, the processor (130) can perform wireless charging.

[0409] In operation 3021, the processor (130) can check if the state of charge (SOC) of the battery (171) exceeds 85% and the current is a light load during wireless charging. If the state of charge (SOC) of the battery (171) exceeds 85% and the current is a light load during wireless charging (operation 3021-Y), the processor (130) can check if the current is a heavy load in operation 3022. If the current is a heavy load (operation 3022-Y), the processor (130) can use capacitive modulation complementarily in operation 3023. Using capacitive modulation can increase the stability of the communication.

[0410] In one embodiment, in operation 3020, when the processor (130) recognizes the accessory cover (1) and the charging station (200), in operation 3024, the processor (130) can perform an operation to improve MPP efficiency while simultaneously performing wireless charging. In one embodiment, when the temperature of the electronic device reaches a threshold value while wireless charging is in progress with default values, the processor (130) can perform an operation to improve MPP efficiency. In operation 3025, the processor (130) can adjust the MPP communication cycle and voltage. In operation 3026, the processor (130) can optimize the dummy load according to the voltage.

[0411] In one embodiment, in operation 3020, when the processor (130) recognizes the accessory cover (1) and the charging station (200), in operation 3027, the processor (130) can perform an operation to improve MPP communication while simultaneously performing wireless charging. In one embodiment, when an MPP communication error occurs three or more times, the processor (130) can perform an operation to improve MPP communication. In operation 3028, the processor (130) can optimize the depth and baseline according to the current load.

[0412] An example of current, depth, and baseline according to current load is disclosed in Table 1.

[0413] Load Diameter Light Load Mid Load and Heavy Load Current 600mA or less 600mA or more 1.25A or more Depth 505070 Base Line 7000

[0414] For example, under light load, the processor (130) can raise the baseline to 70mA through a dummy load. Under heavy load, the processor (130) can raise the depth value to 70 to improve the quality of ASK (amplitude shift keying) communication. In one embodiment, in operation 3029, the processor (130) can check whether the digitizer is running while wireless charging is in progress. If the digitizer is running while wireless charging is in progress (operation 3029-Y), in operation 3030, the processor (130) can update the digitizer recognition software to increase the recognition rate of the digitizer. While wireless charging of the electronic device (101) is in progress, the processor (130) can adjust the LC resonant frequency by updating the digitizer recognition software so that it can recognize the digitizer.

[0415] A device (1) according to one or more embodiments of the present disclosure described above may include at least one connector (or contact) that can be electrically connected to an electronic device (101). Power may be transmitted through the at least one connector.
