FIG. 4 is a plan view illustrating coupling of some components of the electronic device of FIG. 3 according to an embodiment of the disclosure.


Referring to FIG. 4 illustrates an example of coupling two devices (or electronic components) that may be mounted in the electronic device 300 to a circuit board 430. For example, FIG. 4 illustrates an example of a structure in which a first device 410 (or a first electronic component) and a second device 420 (or a second electronic component) are fixed (or coupled) to a specified position (e.g., a groove for fixing each of the first device 410 and the second device 420) of the circuit board 430 in the electronic device 300.


In various embodiments, at one side of the circuit board 430, at least one electronic component may be provided. For example, the circuit board 430 may mechanically (or physically) fix the first device 410, the second device 420, and various electronic components (e.g., processor, memory, and/or interface) and may be the PCB 340 of FIG. 3 configured to connect by a circuit (or electrically) based on a circuit design between the respective electronic components.


In various embodiments, each of the first device 410 and the second device 420 may be mounted within a housing (e.g., the side bezel structure 310) of the electronic device 300 and be an electronic component including a magnetic substance. According to an embodiment, the first device 410 may be an electronic component (e.g., the receiver 341 of FIG. 3) including the first magnetic substance in the electronic device 300. According to an embodiment, the second device 420 may be an electronic component (e.g., the back-facing camera 343 of FIG. 3) including a second magnetic substance in the electronic device 300. In various embodiments, the devices 410 and 420 may include the foregoing electronic components and various other electronic components (e.g., magnetic sensor, acceleration sensor, and speaker) including a magnetic substance.


According to an embodiment, when the devices 410 and 420 are mounted adjacent to each other in the electronic device 300, magnetic substances of the devices 410 and 420 may affect each other; thus, an error may occur in an operation of the devices 410 and 420. To prevent such an error, electronic devices are designed to shield a magnetic force with a device or a shield structure disposed adjacent to the device and made of a conductive material (e.g., SUS, ferrite).


According to various embodiments, the electronic device 300 may include a shield structure for shielding a magnetic force by a first magnetic substance or a second magnetic substance between the first device 410 including a first magnetic substance and the second device 420 including a second magnetic substance. Hereinafter, a shield method by a shield structure for shielding a magnetic force and a structure thereof will be described in detail.


Hereinafter, in various embodiments, for convenience of description, it is described that the first device (or the first electronic component) and the second device (or the second electronic component) include respective magnetic substances, but the disclosure is not limited thereto. For example, in various embodiments, in a structure in which either the first device or the second device includes a magnetic substance and in which the other device does not include a magnetic substance, the disclosure may be applied to a structure that shields at least part of a magnetic force generated by the device including the magnetic substance. According to an embodiment, in a structure in which the first device includes a magnetic substance and in which the second device does not include a magnetic substance, the disclosure may include a structure that shields at least part of a magnetic force generated by the magnetic substance of the first device.



FIG. 5 is a diagram illustrating a shield structure for shielding a magnetic force from a device including a magnetic substance in an electronic device according to various embodiments of the disclosure.


Referring to, FIG. 5 is a diagram schematically illustrating one side of the electronic components taken along line A-A′ of FIG. 4.


Referring to FIG. 5, an electronic device 500 may include a first device 510 (e.g., the receiver 410 of FIG. 4) including a first magnetic substance 515, a second device 520 (e.g., the back-facing camera of FIG. 4) including a second magnetic substance 525, a circuit board 530 (e.g., the PCB 430 of FIG. 4), and a shield structure 560 for shielding at least part of a magnetic force generated between the first magnetic substance 515 and the second magnetic substance 525. In various embodiments, the first device 510 and the second device 520 include magnetic substances 515 and 525, respectively, but the disclosure is not limited thereto. Therefore, the disclosure may include a structure in which any one device (e.g., the first device 510) includes a magnetic substance (e.g., the first magnetic substance 515) and in which the other device (e.g., the second device 520) does not include a magnetic substance (e.g., the second magnetic substance 525). For example, in various embodiments, the disclosure may include a structure in which at least part of a magnetic force generated by the first magnetic substance 515 of the first device 510 is shielded not to affect the second device 520 that does not include a magnetic substance.


According to an embodiment, the shield structure 560 may include a magnetic force shield member (or shield portion) 540 for shielding a magnetic force and a connecting member (or connection portion) 550 for physically fixing the shield member 540 to the circuit board 530.


In various embodiments, the shield member 540 may be disposed between the first device 510 and the second device 520. The shield member 540 may be made of a shield material (or a first material metal or a magnetic material) capable of shielding at least part of a magnetic force generated between the first magnetic substance 515 and the second magnetic substance 525. According to an embodiment, the shield material may be a material (metal) including the property of a ferromagnetic material. For example, the shield material may be implemented with SUS (e.g., an element such as iron (Fe), cobalt (Co), and nickel (Ni) or an alloy).


In various embodiments, the connecting member 550 may contact (or physically connected to) at least part of the shield member 540 based on a portion of one side thereof and may contact (or physically connected to) and be fixed to the circuit board 530 based on the other side thereof. The connection member 550 may be made of a nonmagnetic material (or a second material metal) that may be magnetically separated from at least part of a magnetic force generated between the first magnetic substance 515 and the second magnetic substance 525. According to an embodiment, the nonmagnetic material may be a material (metal) that is not affected by a magnetic field formed by a magnetic substance (e.g., magnet). For example, the nonmagnetic material may be implemented using nickel silver (or pure iron).


In various embodiments, the shield structure 560 (e.g., the shield member 540, the connecting member 550) may be disposed (e.g., formed in a surface mount device (SMD) method) at the circuit board 530 in a particular manner to contact the circuit board 530. According to an embodiment, in implementing the shield structure 560, the shield structure 560 may be divided into the shield member 540 (e.g., material for magnetic field absorption (e.g., magnetic material)) for shielding a magnetic force and the connecting member 550 (e.g., non-magnetized material (e.g., nonmagnetic material), and a shield structure may be implemented by joining two materials (e.g., the shield member 540 and the connecting member 550). In the case of a shield structure according to various embodiments, the nonmagnetic material (e.g., the connecting member 550) formed with an SMD method may be designed to secure only a minimum area to be formed with an SMD method, thereby more freely designing a contact structure and/or position between the device (or a magnetic substance of the device) and the circuit board 530.


According to various embodiments, a disposition position (e.g., a position adjacent to any one device) of the shield member 540 may be determined according to whether functional characteristics (or driving (operation) method) of the device (e.g., the first device 510, the second device 520) are affected by a magnet (or magnetic force, magnetic field) between the first device 510 and the second device 520. According to an embodiment, the shield member 540 may be disposed closer (or leaned) to any one device (e.g., the first device 510 including a magnetic substance that affects an operation of another device) based on at least the functional characteristics of the first device 510 and the second device 520. According to an embodiment, the shield member 540 may have different structures in a distance and/or thickness from that of a device in which a disposition position is determined so as to correspond to the intensity (or magnetic force) of each magnetic substance between the first magnetic substance 515 and the second magnetic substance 525.


According to an embodiment, magnetic fluxes emitted from each of the magnetic substances (e.g., the first magnetic substance 515, the second magnetic substance 525) of electronic components (e.g., the first device 510 and the second device 520) of the electronic device 500 may be different in intensity thereof. For example, the first magnetic substance 515 provided in the first device 510 may have stronger magnetic properties than the second magnetic substance 525 provided in the second device 520. Further, the device may have a second driving method (or driving function) (e.g., an auto focus (AF) function of a camera, a zoom in/out function) affected by a magnetic flux of a magnetic substance of another device or the device may have a first drive method (e.g., a device that is not affected by other magnetic fluxes in driving, such as a speaker) that is not affected by a magnetic flux of a magnetic substance of another device. In an embodiment, a device including a first driving method and/or relatively strong magnetism may be referred to as a first device 510 and a device including a second driving method and/or relatively weak magnetism may be referred to as a second device 520.


According to an embodiment, a magnetic flux emitted from the second magnetic substance 525 of the second device 520 may not significantly affect an operation of the first device 510, but a magnetic flux emitted from the first magnetic substance 515 of the first device 510 may cause a serious error in an operation of the second device 520. According to an embodiment, the shield member 540 may absorb a magnetic force of the first magnetic substance 515 of the first device 510 to form a magnetic field with the first magnetic substance 515. Therefore, when a length B between the shield member 540 and the second device 520 (or the second magnetic substance 525 of the second device 520) is short (or as the shield member 540 and the second device 520 are disposed adjacent to each other, when the shield member 540 and the second device 520 belong to a magnetic field range), a magnetic flux emitted through the shield member 540 may affect an operation of the second device 520.


Therefore, the shield structure 560 of the electronic device 500 according to various embodiments may be disposed adjacent to a device of a first driving method and/or a device (e.g., the first device 510) that emits a relatively strong magnetic flux among the first device 510 and the second device 520.


According to an embodiment, as illustrated in FIG. 5, the shield structure 560 (in particular, the shield member 540) may be disposed closer to the first device 510 rather than the second device 520. Thereby, even within a fixed (or limited) length A between the first device 510 and the second device 520, a separation distance (e.g., length B) between the shield member 540 and the second magnetic substance 525 (e.g., a magnetic substance to be unshielded that may be affected by a magnetic force) may be maximally secured (e.g., maximum separation distance). According to an embodiment, a distance (e.g., length A) between the first device 510 and the second device 520 may include a first radius (e.g., about 15 mm, about 20 mm), and a distance (e.g., length B) between the shield member 540 and the second magnetic substance 525 may include a second radius (e.g., about 10 mm, about 15 mm) smaller than the first radius.


Hereinafter, a structure of the shield structure 560 for shielding a magnetic force in the electronic device 500 according to various embodiments will be described in detail. In the following description, for convenience of description, it is described that the first device 510 and the second device 520 each include a magnetic substance, but in a structure in which only the first device 510 includes a magnetic substance and in which the second device 520 does not include a magnetic substance, the electronic device 500 may include a structure that shields at least part of a magnetic force generated by the magnetic substance of the first device 510.



FIGS. 6, 7, 8, and 9 are diagrams illustrating a structure for shielding a magnetic force from a device including a magnetic substance in an electronic device according to various embodiments of the disclosure.


Referring to, FIG. 6 is a plan perspective view illustrating an example in which the shield structure 560 (e.g., the shield member 540, the connecting member 550) is disposed between two devices (e.g., the first device 510, the second device 520) and contacts (or is coupled to) the circuit board 530. FIG. 7 is a cut-away perspective view taken along line B-B′ of FIG. 6. FIG. 8 is a diagram illustrating a projection perspective view illustrating a form in which the shield structure 560 contacts (or is connected to) the circuit board 530 in FIG. 6. FIG. 9 is a rear perspective view illustrating a form in which the shield structure 560 contacts the circuit board 530 in FIG. 6.


A contact (connection) structure of the shield structure 560 and the circuit board 530 will be described with reference to FIG. 6.


Referring to FIG. 6, the first device 510 is an electronic component including the first magnetic substance 515; and, in an embodiment, the first device 510 may correspond to a receiver or a speaker. The second device 520 is an electronic component including the second magnetic substance 525; and, in an embodiment, the second device 520 may correspond to a camera. In various embodiments, the device may correspond to various electronic components (e.g., a magnetic sensor, an acceleration sensor) including a magnetic substance in addition to the above-described electronic components.


According to an embodiment, when at least two devices (e.g., the first device 510 and the second device 520) are mounted adjacent to each other in the electronic device 500, at least two magnetic substances (e.g., the first magnetic substance 515 and the second magnetic substance 525) of the devices 510 and 520 may affect the other device in any one direction or the other device in both directions. Accordingly, an error may occur in an operation of the devices 510 and 520. To prevent such an error, the shield member (e.g., the shield members 540 of FIGS. 6 to 9) made of a conductive material (e.g., SUS, ferrite) may be disposed between the devices 510 and 520.


According to an embodiment, the circuit board 530 may form a first groove 630 in which one end (e.g., a first member (or a first reinforcing member) 610 of a connecting member (e.g., a connecting member 550 of FIGS. 6 to 9) may contact one side (e.g., the left side of the circuit board 530 in a viewing direction of FIG. 6) thereof and a second groove 640 in which the other end (e.g., a second member (or second reinforcing member) 620 of the connecting member 550 may contact the other side (the right side surface of the circuit board 530 in a viewing direction of FIG. 6) of an opposite direction of one side.


According to an embodiment, the first groove 630 and the second groove 640 may have a structure including a width of different sizes. For example, the first groove 630 and the second groove 640 may be formed in a structure corresponding to one end (e.g., the first reinforcing member 610) and the other end (e.g., the second member 620) of the contact connecting member 550. According to an embodiment, the first groove 630 may have a width (e.g., a width at which the first reinforcing member 610 may be seated) corresponding to one end (e.g., the first reinforcing member 610) of the connecting member 550, and the second groove 640 may have a width (e.g., a width at which the second reinforcing member 620 may be seated) corresponding to the other end (e.g., the second reinforcing member 620) of the connecting member 550. For example, in FIGS. 6 to 9, the first groove 630 may be relatively smaller than the second groove 640, and the second groove 640 may have a relatively larger width than that of the first groove 630. According to some embodiments, the circuit board 530 may not have the first groove 630 and the second groove 640 and may have a structure that contacts (or adheres to) the connecting member 550 through a lower surface of the circuit board 530.


A structure of the shield structure 560 will be described with reference to FIGS. 6 to 9.


The shield structure 560 may include a shield member 540 including a magnetic property and a connecting member 550 including a nonmagnetic property. According to an embodiment, the shield structure 560 may include a shield member 540 (e.g., a magnetic substance) for shielding a magnetic force and a connecting member 550 for fixing the shield member 540 to the circuit board 530. According to an embodiment, the shield structure 560 may be made of a heterogeneous material such as the shield member 540, which is a magnetic substance, and the connecting member 550, which is a nonmagnetic substance; and the heterogeneous materials are bonded to the circuit board 530 by an SMD method. For example, the shield member 540 may have a property of a ferromagnetic substance capable of shielding a magnetic force, and the connecting member 550 may have a property of a nonmagnetic substance that may be magnetically separated from a magnetic force.


Referring to FIG. 7, the shield member 540 may have a plate-like structure and may contact (physically fixed to) one side of the circuit board 530 through the connecting member 550. According to an embodiment, the shield member 540 may have a bending structure including a first bending portion 740 (e.g., an upper portion in a longitudinal direction in the drawing) and/or a second bending portion (e.g., a lower portion in a longitudinal direction in the drawing). For example, the shield member 540 may be at least partially bent.


According to an embodiment, the bending portion (e.g., the first bending portion 740) of the shield member 540 may have a shape bent in a predetermined direction. According to an embodiment, a bending structure of the shield member 540 may be designed in a shape “custom character” or a shape “custom character” by bending an upper side portion or a lower side portion or may be designed in a shape “custom character” by bending an upper side portion and a lower side portion. For example, the number of bending portions of the shield member 540 may be plural. FIGS. 6 to 9 illustrate an example in which an upper portion of the shield member 540 is designed in a bending structure.


According to an embodiment, the bending portion (e.g., the first bending portion 740) bent in the shield member 540 may be formed in an outward direction of the circuit board 530, for example, in a direction of a device (or magnetic substance of the device) to be shielded. According to an embodiment, a bending angle and a bending direction of the bending portion may be variously implemented according to the magnitude (magnetic force) and/or a size (e.g., height) of the magnetic substance to be shielded. According to an embodiment, the shield member 540 may not include a bending portion or may be bent in a predetermined angle (e.g., 90°, 120°, 150°) (or radius of curvature). According to an embodiment, an entire height (or length) and/or area of the shield member 540 may be the same as or relatively larger than a size (e.g., height and/or area) of the magnetic substance to be shielded. Thereby, larger effects can be expected in formation of a magnetic field with the magnetic substance to be shielded and shielding of a magnetic force.


According to an embodiment, the shield member 540 may be designed to have a variable thickness according to a magnetic force of a magnetic substance to be shielded. For example, the shield member 540 may be designed in a thickness to sufficiently absorb magnetism of the magnetic substance to be shielded. According to an embodiment, the shield member 540 may have a thickness of about 0.15 mm.


According to an embodiment, the shield member 540 may contact (be connected to) the circuit board 530 in an SMD method based on the connecting member 550.


Referring to FIGS. 7, 8, and 9, at one side (e.g., an upper side) of the circuit board 530, at least one electronic component may be provided, and the connecting member 550 contacts the other side (a lower surface 655) of the circuit board 530. According to an embodiment, the connecting member 550 may have a shape that encloses the circuit board 530 in a concave (“custom character”) shape (or “U” shape) structure. According to an embodiment, the connecting member 550 may contact fixing grooves (e.g., the first groove 630, the second groove 640) of both sides (e.g., a portion 635 of the left side and a portion 645 of the right side) of the circuit board 530 and a portion of the lower surface 655 of the circuit board 530.


According to an embodiment, the connecting member 550 may be, for example, a reinforcing member formed with a plurality of portions (e.g., a first portion, a second portion, and a third portion) divided according to a shape and/or function thereof. According to an embodiment, the connecting member 550 may be divided into a first reinforcing member 710 (e.g., vertical member, bar member) that is a first portion of the reinforcing member and for fixing to the first groove 630 of one side of the circuit board 530, a second reinforcing member 720 that is a second portion of the reinforcing member and for fixing to the circuit board 530 through the second groove 640 of the other side of the circuit board 530, or a third reinforcing member 730 (e.g., a bottom member) that is a third portion of the reinforcing member and that contacts the lower surface 655 of the circuit board 530.


According to an embodiment, the first reinforcement member 710 (e.g., a first portion of the reinforcement member) and the second reinforcement member 720 (e.g., a second portion of the reinforcement member) may be fixed vertically to both sides of the third reinforcing member 730 (e.g., a third portion of the reinforcement member). For example, the connecting member 550 may be formed such that the first portion (first region) is disposed to correspond to the first groove 630 of the circuit board 530, the second portion (second region) is disposed to correspond to the second groove 640 of the circuit board 530, and a third portion (third region) contacts a lower surface of the circuit board 530. According to an embodiment, the connecting member 550 may be formed such that the first reinforcing member 710 (e.g., the first portion of the reinforcing member), the second reinforcing member 720 (e.g., the second portion of the reinforcing member), and the third reinforcing member 730 (e.g., the third portion of the reinforcing member) each have different functions (or have different shapes).


According to an embodiment, in the connecting member 550, one surface 810 (e.g., an inner surface) of the first reinforcing member 710 of one end may contact the first groove 630 of the circuit board 530, and at least one surface 820 (e.g., a partial area of the inner surface side) of the second reinforcing member 720 of the other end may contact the second groove 640 of the circuit board 530. According to an embodiment, the shield member 540 may contact the entirety of the other surface 830 (e.g., outer surface) of the second reinforcing member 720. For example, one side of the connecting member 550 may contact the other surface 830 of the second reinforcing member 720.


According to an embodiment, the first reinforcement member 710 and the second reinforcement member 720 may have different widths and lengths (or heights). According to an embodiment, in FIGS. 6 to 9, the first reinforcing member 710 may have relatively smaller width and length than the second reinforcing member 720, and the second reinforcing member 720 may have a relatively larger width and length (e.g., a structure including a wide width and a long length) than the first reinforcing member 710. For example, the second reinforcing member 720 may contact in a larger area in consideration of bending prevention and contact force of the shield member 540.


According to an embodiment, the first reinforcement member 710 may have a height corresponding to (or equal to) a height of the circuit board 530 (e.g., an upper surface of the circuit board 530). The second reinforcing member 720 may protrude in a height higher than that of the circuit board 530 (e.g., a structure protruding from an upper surface of the circuit board 530). For example, the second reinforcing member 720 may have a relatively larger area than the first reinforcing member 710 in consideration of a contact area with the shield member 540. Through such a structure shape, one side (e.g., the inner side) of the second reinforcing member 720 may be fixed to and contact the circuit board 530, and the other side (e.g., the outer side) thereof may be more stably fixed to and contact the shield member 540.


According to an embodiment, the third reinforcing member 730 may have a shape in which the entire upper surface 830 (or the inner surface) contacts the circuit board 530.



FIGS. 10 to 14 illustrate various embodiments of a shield structure according to various embodiments of the disclosure. According to an embodiment, a circuit board (e.g., PCB) may have a relatively small width w between (e.g., a weak part) at least two devices (e.g., a first device, a second device) and may be more easily damaged than other portions of the circuit board. In various embodiments, a shield structure (e.g., shield member, connecting member) may reinforce a narrowly formed portion (e.g., a weak part) between the devices. According to an embodiment, in the circuit board, a shield structure may be disposed in a portion that may benefit from reinforcement (e.g., a weak part), and the shield structure may reinforce the weak part based on an elongated plate-like structure or a bending structure bent in a predetermined angle (e.g., about 90°). According to an embodiment, the connecting member of the shield structure may function as a member for reinforcing strength.



FIG. 10 is a rear perspective view illustrating another form of a shield structure contacting a circuit board according to various embodiments of the disclosure.



FIG. 10 illustrates another form of the shield structure 560 (e.g., the shield member 540 and the connecting member 550) described in the foregoing description with reference to FIGS. 5 to 9. According to an embodiment, as illustrated in FIG. 10, a shield structure 1060 (e.g., a shield member 1040, a connecting member 1050) may have a shape (or structure) corresponding to the shield structure 560 according to the foregoing example and further have a function (e.g., a member for reinforcing strength) for reinforcing strength of the circuit board 1030 using the connecting member 1050.


Referring to FIG. 10, in a circuit board 1030, one end and the other end of the connecting member 1050 may contact through one side of a circuit board 1030 between at least two devices (e.g., a first device (not illustrated), a second device (not illustrated)) and the other side of an opposite direction of one side. According to an embodiment, the circuit board 1030 may further have grooves (e.g., the first groove 630 of FIG. 6, the second groove 640 of FIG. 6) for fixing the connecting member 1050 to at least one of one side or the other side. According to an embodiment, FIG. 10 illustrates an example in which a groove is formed in which one end (e.g., a first member 1010) of the connecting member 1050 may contact any one side (e.g., the left side of the circuit board 1030 in a viewing direction of FIG. 10) of the circuit board 1030.


According to an embodiment, the shield member 1040 of the shield structure 1060 may correspond to the description of the shield member 540 described with reference to FIGS. 5 to 9, and a detailed description thereof will be omitted.


According to an embodiment, the connecting member 1050 of the shield structure 1060 may be extended longer than the connecting member 550 described with reference to FIGS. 5 to 9 to have a length (or width) longer than the connecting member 550. According to an embodiment, in the circuit board 1030, a portion (hereinafter, weak part) between two devices (e.g., a first device (not illustrated), a second device (not illustrated)) may have relatively weaker strength than that of other portions of the circuit board 1030 because of a narrow width w. In various embodiments, the connecting member 1050 of the shield structure 1060 may be used as a reinforcing member for reinforcing strength of the weak part of the circuit board 1030. For example, the connecting member 1050 may function as a member for reinforcing strength.


According to an embodiment, as illustrated in FIG. 10, the connecting member 1050 may be elongated in a direction corresponding to a longitudinal direction of a weak part of the circuit board 1030 to have a shape that covers at least part (e.g., all or some) of the weak part. As illustrated in FIG. 10, in the circuit board 1030, the connecting member 1050 may be formed inward (e.g., a shape in which the weak part and the connecting member 1050 have a step) by a width of a groove 1015 in which one end (e.g., the first member 1010) thereof may contact to have a width w′ smaller than a width w of the weak part. According to an embodiment, a length of the connecting member 1050 may correspond to that of the weak part or may be shorter or longer than that of the weak part according to a fastening structure of the connecting member 1050. According to an embodiment, the connecting member 1050 may have a shape corresponding to that of the weak part.


According to various embodiments, the connecting member 1050 may be disposed in the circuit board 1030 in a specific manner (e.g., formed in a SMD method) to contact the circuit board 1030. In the case of a shield structure according to various embodiments, the nonmagnetic material (e.g., the connecting member 1050) formed with an SMD method may be designed to secure a maximum area (or larger area) to be formed with an SMD method, thereby reinforcing strength of the weak part between the device and the device in the circuit board 1030.



FIG. 11 is a rear perspective view illustrating another form of a shield structure contacting a circuit board according to various embodiments of the disclosure.



FIG. 11 illustrates another form of the shield structure 1060 described with reference to FIG. 10. For example, FIG. 11 illustrates an example of another structure of a connecting member 1150 of a shield structure 1160.


Referring to FIG. 11, in a circuit board 1130, one end and the other end of the connecting member 1150 may contact through one side of the circuit board 1130 between at least two devices (e.g., a first device (not illustrated), a second device (not illustrated)) and the other side, respectively of opposite side of the one side. According to an embodiment, FIG. 11 illustrates an example of a structure in which the circuit board 1130 contacts the connecting member 1150 through one side and the other side without forming grooves in one side and the other side.


According to an embodiment, a shield member 1140 of the shield structure 1160 may correspond to that described with reference to FIGS. 5 to 10, and a detailed description thereof will be omitted.


According to an embodiment, the connecting member 1150 of the shield structure 1160 has an extended width further than that of the connecting member 1050 described with reference to FIG. 10, and a first member 1110 contacting any one side (e.g., the left side of the circuit board 1130 in a viewing direction of FIG. 11) of the circuit board 1130 may have a length corresponding to that of the connecting member 1050. According to an embodiment, the connecting member 1150 may have an extended length by a height of the side surface of the circuit board 1130 at one end of the weak part of the circuit board 1130. According to an embodiment, the first member 1110 may have a structure in which an extended portion of the connecting member 1150 is bent at the end (or edge portion) of a width w of the weak part.


According to an embodiment, as illustrated in FIG. 11, the connecting member 1150 may have a length corresponding to that of the weak part of the circuit board 1130 and have a width corresponding to a width w of the weak part to be formed in a shape (or covering an entire weak part) including an area corresponding to the weak part.



FIG. 12 is a rear perspective view illustrating another form of a shield structure contacting a circuit board according to various embodiments of the disclosure.



FIG. 12 illustrates another form of the shield structure 1160 described with reference to FIG. 11. For example, FIG. 12 illustrates an example of another structure of a connecting member 1250 of a shield structure 1260.


Referring to FIG. 12, a circuit board 1230 may include at least one circuit terminal (or contact portion) (e.g., GND terminal) related to at least one device (e.g., a first device (not illustrated), a second device (not illustrated)). According to an embodiment, the circuit board 1230 may include a circuit terminal for electrical connection of a particular device (e.g., a speaker) in the weak part. FIG. 12 illustrates an example in which a hole 1203 for electrical wiring connection is formed at a position corresponding to a circuit terminal formed in a weak part in the connecting member 1250.


According to an embodiment, a shield member 1240 of the shield structure 1260 may correspond to that described with reference to FIGS. 5 to 10, and a detailed description thereof will be omitted.


According to an embodiment, FIG. 12 illustrates an example in which two circuit terminals (e.g., GND terminals) for electrical connection with a device are formed in the weak part of the circuit board 1230. According to an embodiment, the connecting member 1250 may have two holes 1203 at positions corresponding to each position of the circuit terminals. According to an embodiment, a connection wiring from the device may be connected to circuit terminals of the circuit board 1230 exposed through two holes 1203 of the connecting member 1250. According to an embodiment, as illustrated in FIG. 12, when an area of the connecting member 1250 decreases in order to avoid a circuit terminal, as illustrated in FIG. 11 or 12, a first member 1210 of the connecting member 1250 is extended by a height of the circuit board 1230 (or the weak part) and a portion (e.g., the first member 1210) extended by the height is bent at the end in the width direction of the weak part, thereby reinforcing strength of the weak part.



FIGS. 13 and 14 are diagrams illustrating a shield structure for shielding a magnetic force from a device including a magnetic substance in an electronic device according to various embodiments of the disclosure.


Referring to, FIG. 13 is a diagram schematically illustrating one side of electronic components cut in any one direction in a state in which the device is seated in FIGS. 10 to 12.


Referring to FIG. 13, an electronic device 1300 may include a first device 1301 (e.g., the receiver 410 of FIG. 4) including a magnetic substance 1305, a second device 1302 (e.g., the second device 420 of FIG. 4) that does not include a magnetic substance, a circuit board 1330 (e.g., the PCB 430 of FIG. 4), and a shield structure 1360 for shielding at least part of a magnetic force generated between the first device 1301 and the second device 1302. In various embodiments, the first device 1301 includes a magnetic substance 1305, but the disclosure is not limited thereto. According to various embodiments, the first device 1301 and the second device 1302 each may include a structure including a magnetic substance. For example, the electronic device 1300 of the disclosure may include a structure in which one device (e.g., the first device 1301) includes a magnetic substance, and the other device (e.g., the second device 1302) does not include a magnetic material, or a structure in which one device and at least one other device each include a magnetic substance.


In various embodiments, the electronic device 1300 may include a structure in which at least part of a magnetic force generated by the magnetic substance 1305 of the first device 1301 is shielded so as not to affect at least one second device 1302 affected by the magnetic substance 1305.


According to an embodiment, the shield structure 1360 may include a shield member 1340 for shielding a magnetic force and a connecting member 1350 for physically fixing the shield member 1340 to the circuit board 1330.


In various embodiments, the shield member 1340 may be disposed between the first device 1301 and the second device 1302. The shield member 1340 may be made of a shield material (or first material metal or magnetic material) capable of shielding at least part of a magnetic force between the first device 1301 (or the magnetic substance 1305 of the first device 1301) and the second device 1302. According to an embodiment, the shield material may be a material (metal) including a property of a ferromagnetic material. For example, the shield material may be implemented with SUS (e.g., made of an element or alloy such as iron (Fe), cobalt (Co), and nickel (Ni)).


In various embodiments, the connection member 1350 may contact (or be physically connected to) at least part of the shield member 1340 based on a portion of one side (e.g., the outer side) and may contact (or be physically connected to) the circuit board 1330 based on the other side (e.g., the inner side). According to an embodiment, the connecting member 1350 may be made of a nonmagnetic material (or a second material metal) that may be magnetically separated from at least part of a magnetic force generated between the first device 1301 (or the magnetic substance 1305 of the first device 1301) and the second device 1302. According to an embodiment, the nonmagnetic material may be a material (metal) that is not affected by a magnetic field formed by the magnetic substance (e.g., magnet). For example, the nonmagnetic material may be implemented using nickel silver (or pure iron).


According to various embodiments, the shield structure 1360 (e.g., the shield member 1340, the connecting member 1350) may be disposed (e.g., formed with an SMD method) in the circuit board 1330 in a particular manner to contact the circuit board 1330. According to an embodiment, in implementing the shield structure 1360, the shield member 1340 (e.g., a material for absorbing a magnetic field (e.g., magnetic material) for shielding a magnetic force and the connecting member 1350 (e.g., non-magnetized material (e.g., nonmagnetic material)) may be divided and by bonding between two materials (e.g., the shield member 1340 and the connecting member 1350), a shield structure may be implemented. In the case of a shield structure according to an embodiment, a nonmagnetic material (e.g., the connecting member 1350) to be formed with an SMD method may be designed to secure a minimum area to be formed with an SMD method; thus, a contact structure and/or position between the device (or the magnetic substance of the device) and the circuit board 1330 may be more freely designed. In the case of a shield structure according to an embodiment, a nonmagnetic material (e.g., the connecting member 1350) be formed with an SMD method may be designed to secure a maximum area (e.g., a junction area to be formed with an SMD method in the circuit board 1330) to be formed with an SMD method. Thereby, in various embodiments, the strength of a weak part of the circuit board 1330 may be reinforced (e.g., twist is reinforced), and the connecting member 1350 may be bonded to the circuit board 1330 in a larger area to prevent from separation from the circuit board 1330 of the shield structure 1360.


According to various embodiments, a disposition position (e.g., a position adjacent to a device of any one side) of the shield member 1340 may be determined according to whether functional characteristics (or driving (operation) method) of the device (e.g., the first device 1301, the second device 1302) are affected by a magnet (or magnetic force or magnetic field) between the first device 1301 and the second device 1302. According to an embodiment, the shield member 1340 may be disposed closer (or leaned) to any one device (e.g., the first device 1301 including a magnetic substance that affects an operation of the other device) based on at least functional characteristics of the first device 1301 and the second device 1302. According to an embodiment, the shield member 1340 may have a distance and/or thickness different from the device in which the disposition position is determined to correspond to the magnitude (or magnetic force) of the magnetic substance between the magnetic substance 1305 of the first device 1301 and the second device 1302 (or a magnetic substance (not illustrated) of the second device 1302).


The shield structure 1360 of the electronic device 1300 according to various embodiments may be disposed adjacent to a device (e.g., the first device 1301) that emits a relatively strong magnetic flux among the devices 1301 and 1302. According to an embodiment, as illustrated in FIG. 13, the shield structure 1360 (in particular, the shield member 1340) may be disposed closer to the first device 1301 rather than the second device 1302.


According to various embodiments, the shield member 1340 may have a plate-like structure and may contact (be physically fixed) on one side of the circuit board 1330 through the connecting member 1350. According to an embodiment, the shield member 1340 may form at least one end of both ends (e.g., an upper or lower portion in a length (or height) direction in the drawing) in a bending structure. For example, the shield member 1340 may be at least partly bent.


According to an embodiment, a bending portion of the shield member 1340 may have a shape bent in a predetermined direction. According to an embodiment, a bending structure of the shield member 1340 may be designed in a shape “custom character” or “custom character” by bending of an upper portion or a lower portion or may be designed in a shape “custom character” by bending of an upper portion or a lower portion. For example, the number of bending portions of the shield member 1340 may be plural. According to an embodiment, the shield member 1340 may not include a bending portion and may be formed in a plate-like structure (or a flat plate structure, or a shape “custom character”), as illustrated in FIG. 13.


According to an embodiment, an entire height (or length) and/or area of the shield member 1340 may be equal to or relatively larger than a size (e.g., height and/or area) of a magnetic substance to be shielded.
