[0021] Hereinafter, various embodiments of the present invention will be described with reference to the attached drawings. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that the present invention encompasses various modifications, equivalents, and / or alternatives of the embodiments.

[0022] Embodiments disclosed in this document relate to a button assembly (or side key) including a fingerprint sensor and an electronic device including the button assembly. In one embodiment, the button assembly may include a sensor unit (or fingerprint sensor unit), a printed circuit board connected to the sensor unit, and a dome switch (or dome key) connected to the printed circuit board. The button assembly may include a printed circuit board laminated with a plurality of layers (e.g., four layers) without including a separate support member (e.g., stainless steel) for thickness compensation. In one embodiment, the button assembly may include a printed circuit board laminated with four layers, thereby reducing a width in one direction. The button assembly may include a printed circuit board formed in a stepped shape so that a certain level or higher of waterproof performance can be maintained despite the reduction in width. In one embodiment, the printed circuit board may have a shape in which a portion (or, a center portion, an extended portion) that comes into contact with the dome switch is extended more than the remaining portion (or, a periphery portion). For example, the width of the extended portion of the printed circuit board can be formed to be larger than the width of the remaining portion by a specified value, and the specified value can be set to be larger than the minimum width to which a waterproof material can be applied. Since the printed circuit board disposed between the sensor portion of the button assembly and the dome switch is composed of a four-layer laminated substrate and at least one portion is formed in an extended shape, the width of the button assembly can be reduced in at least one direction, and waterproof performance can be secured. At least a part of a conductive portion (or, electrical material) of an electronic device disposed adjacent to the printed circuit board of the button assembly can be removed, and interference that may occur between the button assembly and the conductive portion in a pressed state of the button assembly can be prevented.

[0024] FIG. 1b is a drawing showing one form of a side and back side of an electronic device according to one embodiment.

[0025] FIG. 2 is an exploded perspective view of a portion of an electronic device according to one embodiment.

[0026] Referring to FIGS. 1A to 2, in one embodiment, the electronic device (100) may include a first housing (110) (e.g., a first housing structure) including a first side member (113) (e.g., a side bezel) and a second housing (120) (e.g., a second housing structure) including a second side member (123) (e.g., a side bezel) that are foldably coupled to each other with respect to a folding axis (F) through at least one hinge device (140, 140-1) (e.g., a hinge module or a hinge structure). For example, the first housing (110) and the second housing (120) may be configured as a foldable housing (e.g., a housing structure). For example, the electronic device (100) may include a first display (130) (e.g., a flexible display, a foldable display, or a main display) arranged to be supported by a first housing (110) and a second housing (120). For example, the first housing (110) may include a first plate (111) (e.g., a first side) facing a first direction (e.g., a z-axis direction) and a second plate (112) (e.g., a second side) facing a second direction (e.g., a -z-axis direction) opposite to the first direction. For example, the second housing (120) may include a third plate (121) (e.g., a third side) and a fourth plate (122) (e.g., a fourth side) facing a direction opposite to the third plate (121) (e.g., a third side). For example, the first housing (110) may include a first rear cover (114) coupled with a first side member (113). For example, the second housing (120) may include a second rear cover (124) coupled with a second side member (123). For example, when the electronic device (100) is in a fully unfolded first state (e.g., an unfolded state or an unfolded state), the first plate (111) and the third plate (121) may be operated such that they face substantially the same direction (e.g., a z-axis direction).For example, when the electronic device (100) is in a fully folded second state (e.g., a folded state or a folded state), the first plate (111) and the third plate (121) may be operated so that they face each other or face in opposite directions. For example, the electronic device (100) may also be operated so as to maintain a third state (e.g., an intermediate state) between the first state and the second state.

[0027] FIG. 1B illustrates one form of a rear side (e.g., a portion composed of a first rear cover (114) and a second rear cover (124)) and a side side (e.g., a portion composed of a first side member (113) and a second side member (123)) of an electronic device (100). Reference numeral 11 of FIG. 1B illustrates one example of a rear side of the electronic device (100), reference numeral 12 illustrates one example of an upper side (e.g., a side facing the y-axis) of the electronic device (100), reference numeral 13 illustrates one example of a lower side (e.g., a side facing the -y-axis) of the electronic device (100), and reference numeral 14 illustrates one example of a left side (e.g., a side facing the x-axis) of the electronic device (100). Hereinafter, “the side of the electronic device (100)” or “the side of the first housing (110)” may be referred to as the left side.

[0028] In one embodiment, the electronic device (100) may include a first receiver (101), at least one first sensor module (104) (e.g., an ambient light sensor) and / or at least one first camera module (105) (e.g., a UDC, under display camera) disposed on a first plate (111) of a first housing (110). In one embodiment, the electronic device (100) may include at least one second camera module (108) and / or a flash disposed on a second plate (112) of the first housing (110) (e.g., a first rear cover (114)). In one embodiment, the electronic device (100) may include a second display (131), at least one third camera module (125) (e.g., a UDC, under display camera), at least one second sensor module and / or a second receiver disposed on a fourth plate (122) of a second housing (120). For example, the second display (131) may be arranged to be visible from the outside through at least a portion of the second rear cover (124).

[0029] In one embodiment, the electronic device (100) may include at least one key (106, 160) (or button), a microphone (103), a vent hole (115), and / or a connector port (107) disposed on a first side member (113). For example, a sound control key (106) (or volume key) and a button assembly (160) (or side key, side button, side key, power key) may be disposed on a left side of the electronic device (100). As an example, the button assembly (160) may be disposed below the sound control key (106) (e.g., in the -y-axis direction). The button assembly (160) may be in a form in which at least a portion thereof protrudes from a side of the electronic device (100) (e.g., a surface of the first side member (113) facing the x-axis) in a direction perpendicular to the side (e.g., in the x-axis direction). The button assembly (160) may be formed to be pressable from the outside of the electronic device (100). The button assembly (160) may include a fingerprint sensor for fingerprint sensing, and at least a portion of the button assembly (160) in which the fingerprint sensor is disposed may be visible to the outside through an opening formed in the first side member (113). For example, a microphone (103) and a vent hole (115) may be disposed on an upper side of the electronic device (100). For example, a microphone (103) and a connector port (107) may be disposed on a lower side of the electronic device (100). In one embodiment, the electronic device (100) may include a speaker (102) disposed on a second side member (123). At least some of the components described above may be disposed in the first housing (110) and / or the second housing (120). For convenience of explanation, in FIG. 3 and below, the structure in which the button assembly (160) is placed in the first housing (110) is described.

[0030] In one embodiment, the first display (130) (e.g., a flexible display) may include a first region (130a) (e.g., a first planar portion) corresponding to at least a portion of the first plate (111), a second region (130b) (e.g., a second planar portion) corresponding to at least a portion of the third plate (121), and a third region (130c) (e.g., a flexible portion) connecting the first region (130a) and the second region (130b) and allowing the electronic device (100) to be deformed in a second state (e.g., a folded state) and / or a third state. For example, the third region (130c) may be positioned to at least partially overlap at least one hinge device (140, 140-1) when the first display (130) is viewed from above (e.g., in the z-axis direction). For example, the first display (130) may be arranged so as not to be visible from the outside in the second state by having the first plate (111) and the third plate (121) face each other (e.g., inward-fold type). For example, the first display (130) may be arranged so as to be visible from the outside in the second state by having the first plate (111) and the third plate (121) face each other in opposite directions (e.g., outward-fold type).

[0031] In one embodiment, the electronic device (100) may include at least one hinge device (140, 140-1) (e.g., a hinge module or a hinge structure) connecting the first housing (110) and the second housing (120) under the first display (130) (e.g., in the -z-axis direction). For example, the at least one hinge device (140, 140-1) may include a first hinge device (140) and a second hinge device (140-1) spaced apart from the first hinge device (140) along a direction parallel to the folding axis (F) (e.g., in the ±y-axis direction). For example, at least one hinge device (140, 140-1) may be supported by a first support member (1131) extending from the first side member (113) to the first space (1101) of the first housing (110) and a second support member (1231) extending from the second side member (123) to the second space (1201) of the second housing (120). For example, at least one hinge device (140, 140-1) may be arranged so as not to be visible from the outside through a hinge housing (150) (e.g., a hinge cover) between the first housing (110) and the second housing (120).

[0032] In one embodiment, the first hinge device (140) may include a first rotation member (141) (e.g., a first arm or a first rotator) disposed on a first support member (1131) of the first housing (110), a second rotation member (142) (e.g., a second arm or a second rotator) disposed on a second support member (1231) of the second housing (120), and a gear assembly (143) connected to the first rotation member (141) and the second rotation member (142) such that the first housing (110) and the second housing (120) rotate symmetrically with respect to each other. For example, the gear assembly (143) may include a plurality of gears (e.g., spur gears and / or worm gears) gear-coupled to one another. For example, the gear assembly (143) may include a cam coupling structure for urging the first housing (110) and the second housing (120) in a direction in which they are to transition from a first state (e.g., an unfolded state or an unfolded state) to a second state (e.g., a folded state or a folded state) or in a direction in which they are to transition from the second state to the first state, based on a predetermined angle, and for providing a free stop at various folding angles. For example, the second hinge device (140-1) may have substantially the same configuration as the first hinge device (140).

[0033] In one embodiment, the electronic device (100) may include a first hinge plate (151) connected to a first support member (1131) and / or a first rotation member (141). The electronic device (100) may include a second hinge plate (152) connected to a second support member (1231) and / or a second rotation member (142). For example, at least one hinge device (140, 140-1), the first rotation member (141), the second rotation member (142), the first hinge plate (151), and the second hinge plate (152) may form substantially the same plane as the first support member (1131) and the second support member (1231) when the electronic device (100) is in a first state. For example, the second hinge device (140-1) may be substantially symmetrical with the first hinge device (140) or may have a substantially identical configuration.

[0034] FIG. 3 is an exploded perspective view of a portion of a first housing including a button assembly according to one embodiment.

[0035] FIG. 3 shows a view from the -z axis with the first rear cover (e.g., the first rear cover (114) of FIG. 1b) removed from the first housing (e.g., the first housing (110) of FIG. 1a).

[0036] Referring to FIG. 3, in one embodiment, an electronic device (e.g., the electronic device (100) of FIG. 1A) may include a button assembly (160) (e.g., the button assembly (160) of FIG. 1B) at least partially exposed through a portion of a side surface. For example, at least a portion of the button assembly (160) may be exposed through a side surface (e.g., a surface facing the x-axis) of a first side member (113) of a first housing (110). The button assembly (160) may be at least partially exposed through the side surface of the first housing (110) to recognize a fingerprint of a user of the electronic device (100). At least a portion of a portion of the button assembly (160) disposed inside the first housing (110) may be connected to a printed circuit board (or main printed circuit board, first printed circuit board) (e.g., the first printed circuit board (170) of FIG. 9) disposed inside the first housing (110) (e.g., the first space (1101) of FIG. 2). For example, the button assembly (160) may include at least one circuit that is electrically connected to the printed circuit board and processes whether the button assembly (160) is pressed and / or whether fingerprint recognition is activated based on whether the button assembly (160) is pressed. In one embodiment, at least a portion of the button assembly (160) may be disposed below a sound control key (106) disposed on a side surface of the first housing (110). For example, a portion of the button assembly (160) exposed through the side surface of the first housing (110) may be disposed in the -y-axis direction relative to the sound control key (106).

[0037] FIGS. 4 and 5 are drawings showing an example of a shape of a button assembly according to one embodiment, viewed from various angles.

[0038] Reference numeral 401 in FIG. 4 represents an example of a button assembly (160) as viewed from the -z axis, and reference numeral 402 represents a part of reference numeral 401 as viewed from the -y axis. Reference numeral 501 in FIG. 5 represents an example of a button assembly (160) as viewed from the -y axis, and reference numeral 502 represents an example of a button assembly (160) as viewed from the x axis.

[0039] With reference to FIGS. 4 and 5, in one embodiment, a button assembly (160) may include a sensor portion (161) at least partially exposed through a side surface (e.g., a side facing the x-axis) of an electronic device (e.g., the electronic device (100) of FIG. 1A), a second printed circuit board (163) in contact with the sensor portion (161) and connected to a first printed circuit board (e.g., the first printed circuit board (170) of FIG. 9) of the electronic device (100), and a dome switch (167) in contact with a side of the second printed circuit board (163) opposite to the side in contact with the sensor portion (161). The sensor portion (161) may include a first side (1611) exposed through the side surface of the electronic device (100) (e.g., a side facing the x-axis) and a second side (1612) opposite to the first side (1611) (e.g., a side facing the -x-axis). The sensor unit (161) may include a flange (1610) that is at least partially in contact with an inner surface (e.g., a surface facing the -x axis) of the first housing (110). At least one sensor (e.g., a fingerprint sensor) included in the sensor unit (161) may receive an external physical stimulus (e.g., a fingerprint contact) through the first surface (1611). A second surface (1612) of the sensor unit (161) may be in contact with a second printed circuit board (163). For example, the second surface (1612) may be a surface of the flange (1610) facing the -x axis.

[0040] The second printed circuit board (163) may include a rigid printed circuit board (RPCB) (164) that is in contact with the sensor portion (161) and the dome switch (167) and a flexible printed circuit board (FPCB) that extends from at least a portion of the rigid printed circuit board (164). For example, one end of the rigid printed circuit board (164) (e.g., an end facing the x-axis) may be in contact with at least a portion of the sensor portion (161) (e.g., a flange (1610)). The other end of the rigid printed circuit board (164) (e.g., an end facing the -x-axis) may be in contact with the dome switch (167). The flexible printed circuit board (165) may be formed to extend to connect the rigid printed circuit board (164) and the first printed circuit board (e.g., the first printed circuit board (170) of FIG. 9) disposed within the first housing (110).

[0041] For example, the flexible printed circuit board (165) may include an extension portion extending from the rigid printed circuit board (164) and a bend portion extending in a curved manner toward the first printed circuit board (170). For example, the flexible printed circuit board (165) may include a first extension portion (1651) extending downwardly (e.g., toward the z-axis) from the rigid printed circuit board (164), a bend portion (1652) (or, a bend portion, a second extension portion) extending upwardly (e.g., toward the -z-axis) from the first extension portion (1651) in a different direction, a third extension portion (1653) extending in a third direction (e.g., toward the -x-axis) perpendicular to a side surface (e.g., a surface facing the x-axis) of the electronic device (100) from the second extension portion (1652), and a fourth extension portion (1654) extending from the third extension portion (1653) toward the first printed circuit board (170) (e.g., toward the y-axis). At least a portion of the flexible printed circuit board (165) may be formed to fold in response to pressing of the sensor portion (161). For example, at least a portion of the first extension portion (1651) and / or at least a portion of the bending portion (1652) may be bent to become closer to each other as the first surface (1611) of the sensor portion (161) is pressed in the third direction. At least a portion of the flexible printed circuit board (165) may be connected to the first printed circuit board (170). For example, the fourth extension portion (1654) may include a connector that is physically and / or electrically connected to the first printed circuit board (170). The first printed circuit board (170) and the second printed circuit board (163) may be electrically connected through the fourth extension portion (1654), and at least one electrical circuit comprising the sensor portion (161), the second printed circuit board (163), the dome switch (167), and the first printed circuit board (170) may be formed. For example, the first printed circuit board (170) may include at least one processor that processes a signal (or data) related to whether the dome switch (167) is pressed or not transmitted through the electric circuit.For example, the processor of the first printed circuit board (170) may be set to detect the pressing of the dome switch (167) and activate the fingerprint sensor of the sensor unit (161) when the dome switch (167) is pressed.

[0042] In one embodiment, the shape of the flexible printed circuit board (165) is not limited to the above-described content and may be formed in various forms. For example, each part (e.g., the first extension part (1651), the bending part (1652), the third extension part (1653), and the fourth extension part (1654)) of the flexible printed circuit board (165) may be deformed into an appropriate shape within the available range of the internal space of the first housing (110) (e.g., the first space (1101) of FIG. 2). Hereinafter, for convenience of explanation, the first extension part (1651) of the flexible printed circuit board (165) may be defined as a part where extension in the first direction (e.g., the z-axis direction) from the rigid printed circuit board (164) begins. The bending portion (1652) of the flexible printed circuit board (165) may be defined as a portion including one end of the flexible printed circuit board (165) in a first direction, a portion that is bent to the left (e.g., in the x-axis direction) of the end, and a portion that is bent to the right (e.g., in the -x-axis direction) of the end in a second direction (e.g., in the -z-axis direction). Alternatively, in one embodiment, the second printed circuit board (163) itself may be referred to as a flexible printed circuit board that includes at least a partially flexible portion (e.g., the flexible printed circuit board (165)).

[0044] Reference numeral 601 in FIG. 6 represents the shape of the sensor portion (161) of the button assembly (160), a portion of the second printed circuit board (163), and the dome switch (167), and reference numeral 602 represents a portion of the button assembly (160) viewed from the -x-axis direction.

[0045] Referring to FIG. 6, in one embodiment, the second printed circuit board (163) may include a third surface (1641) in contact with the sensor portion (161) and a fourth surface (1642) in contact with the dome switch (167). Conductive pads may be arranged on the third surface (1641) and the fourth surface (1642) of the second printed circuit board (163). The second printed circuit board (163) may include a first portion (1645) (or a central portion, a center portion) in contact with the dome switch (167) and a second portion (1646) (or a peripheral portion) located on both sides of the first portion (1645) (e.g., in the y-axis direction and the -y-axis direction). The first portion (1645) may be formed to have a larger width in at least one direction (e.g., in the z-axis direction) than the second portion (1646). For example, a first width (W1) of the first portion (1645) in a first direction (e.g., in the z-axis direction) may be formed to be larger than a second width (W2) of the second portion (1646) in the first direction. For example, the first portion (1645) may include an area that extends upward (e.g., in the -z-axis direction) and downward (e.g., in the z-axis direction) of the dome switch (167) compared to the second portion (1646). For example, the first width (W1) of the first portion (1645) may be formed to be larger than a third width (W3) of the dome switch (167) in the first direction. For example, the first width (W1) of the first portion (1646) may be formed to be substantially the same as a fourth width (W4) of the flange (1610) in the first direction.

[0046] The second width (W2) of the second portion (1646) may be formed smaller than the fourth width (W4) of the sensor portion (161) in the first direction. For example, the second width (W2) of the second portion (1646) may be formed to be substantially the same as the third width (W3) of the dome switch (167) in the first direction. For example, the second width (W2) of the second portion (1646) may be formed smaller than the fourth width (W4) of the flange (1610) so that at least a portion of the second printed circuit board (163) may move inwardly of the sensor portion (161) when the first surface (1611) of the sensor portion (161) is pressed.

[0047] The first portion (1645) may include a first step surface (16451) (e.g., a surface facing the z-axis) that protrudes further in the first direction than the second portion (1646). For example, the first step surface (16451) of the first portion (1645) may protrude further in the first direction than the second step surface (16461) of the second portion (1646) that faces the first direction. The first portion (1645) may include a curved surface (16452) (or, an inclined surface) that smoothly connects the first step surface (16451) and the second step surface (16461). For example, the first portion (1645) may be formed to be stepped in a direction parallel to the y-axis with respect to the second portion (1646). For example, the first part (1645) and the second part (1646) may be formed so that the distances in the first direction to the first plate (e.g., the first plate (111) of FIG. 1A) are different from each other.

[0048] The rigid printed circuit board (164) may include a first portion (1645) and a second portion (1646), and the flexible printed circuit board (165) may be formed to extend from at least a portion of the second portion (1646). For example, the flexible printed circuit board (165) may be formed to extend from a second-first portion (1646_1) positioned to the left (e.g., along the -y axis) of the first portion (1645) or a second-second portion (1646_2) positioned to the right (e.g., along the y axis). As an example, the flexible printed circuit board (165) may include an extension (e.g., the first extension (1651) of FIG. 4) that extends from a surface of the second-second portion (1646_2) facing the first direction. For example, the flexible printed circuit board (165) may include a draw out part (1650) that is drawn out (or extends from) one side (e.g., the side facing the z-axis) of the second part (1646).

[0049] In one embodiment, the second printed circuit board (163) may be configured as a substrate assembly (or substrate array, composite array) including printed circuit boards formed in different layers. For example, the second printed circuit board (163) may include a rigid printed circuit board (164) (or rigid portion) formed in four or more layers (e.g., four layers, or five layers) and a flexible printed circuit board (165) (or flexible portion) formed in two layers. For example, the second printed circuit board (163) may include a rigid printed circuit board (164) formed as a four-layer printed circuit board including four different wiring layers (or wiring layers, signal layers) and a flexible printed circuit board (165) formed as a two-layer printed circuit board including two different wiring layers. In one embodiment, the rigid printed circuit board (164) and the flexible printed circuit board (165) of the second printed circuit board (163) may share at least one layer. For example, the flexible printed circuit board (165) may be an extension of some of the layers constituting the rigid printed circuit board (164). In one embodiment, the second printed circuit board (163) may be a composite printed circuit board (or rigid-flexible printed circuit board) (e.g., RFPCB, rigid-flexible printed circuit board) that includes a rigid portion that is formed relatively rigidly so that various electrical components can be mounted thereon and a soft portion that is formed relatively flexibly for connection with another printed circuit board (e.g., the first printed circuit board (170) of FIG. 9). A waterproof material (166) may be applied to at least a portion of the button assembly (160) to ensure waterproof performance. For example, a waterproofing material may be applied between the sensor portion (161) and the second printed circuit board (163) and between the second printed circuit board (163) and the dome switch (167).For example, the waterproofing material may be filled between a plurality of conductive pads (e.g., 1646a) arranged on a third side (1641) of the rigid printed circuit board (164). For example, the waterproofing material may be filled between a plurality of conductive pads (not shown) arranged on a fourth side (1642) of the rigid printed circuit board (164). The waterproofing material may be filled in various ways, such as underfill, overfill, or sidefill. For example, at least some of the plurality of conductive pads arranged on the third side (1641) may be waterproofed by underfill, and at least some of the plurality of conductive pads arranged on the fourth side (1642) may be waterproofed by overfill.

[0050] For example, a waterproofing material may be filled into the lower portion (e.g., on the surface facing the -x-axis of the sensor portion (161)) of a plurality of conductive pads (e.g., 1646a) arranged on the third surface (1641) (or a plurality of conductive pads arranged on the third surface (1641) of the first portion (1645) and the second portion (1646)). For example, when the button assembly (160) is viewed in the -x-axis direction, at least a portion of a waterproofing material (e.g., 1661) filled in an underfill manner into the lower portion (e.g., in the x-axis direction) of the second printed circuit board (163) (or, on the upper portion of the second surface (1612) of the sensor portion (161)) may be visible. At least some of the plurality of conductive pads arranged on the fourth surface (1642) (or, the plurality of conductive pads arranged on the fourth surface (1642) of the first portion (1645)) may be filled with a waterproofing material on the upper portion (e.g., in the -x-axis direction). For example, the waterproofing material may be applied on an area that extends in the first direction and / or the second direction (e.g., in the -x-axis direction) compared to the second portion (1646) of the first portion (1645), and may be filled between the plurality of pads of the dome switch (167). For example, when the button assembly (160) is viewed in the -x-axis direction, at least some of the waterproofing material (e.g., 1662) filled in an overfill manner on the upper portion (e.g., in the -x-axis direction) of the second printed circuit board (163) may be visible. The waterproofing material may include, for example, a synthetic resin (e.g., a resin).

[0051] By forming the first part (1645) of the second printed circuit board (163) in an expanded shape compared to the second part (1646), the waterproof performance of the button assembly (160) can be secured. For example, as the electronic device (e.g., the electronic device (100) of FIG. 1A) becomes smaller, the width of the button assembly (160) in the first direction (e.g., the z-axis direction) can be reduced, and the width of the second printed circuit board (163) in the first direction can also be reduced. As the width of the second printed circuit board (163) in the first direction (e.g., the second width (W2)) is reduced, a first part (1645) having a larger width than the width of the dome switch (167) in the first direction (e.g., the third width (W3)) can be formed on the second printed circuit board (163) in order to waterproof the pad of the dome switch (167). Due to the formation of the first part (1645), a device (e.g., a nozzle) for applying a waterproofing material between the first part (1645) and the dome switch (167) can be stably positioned. The waterproofing material (e.g., 1662) can be filled in the pad area of ​​the dome switch (167) on the first part (1645) (e.g., in the -x-axis direction), and the waterproofing performance of the button assembly (160) can be secured.

[0052] FIG. 7 is a drawing showing an example of a laminated structure of a printed circuit board according to one embodiment.

[0053] Referring to FIG. 7, in one embodiment, a rigid printed circuit board (e.g., the rigid printed circuit board (164) of FIG. 4) of a second printed circuit board (e.g., the second printed circuit board (163) of FIG. 4) may include a plurality of layers (1640). For example, the rigid printed circuit board (164) may be in the form of four different layers stacked together (or a four-layer printed circuit board). For example, the plurality of layers (1640) may include a first layer (164a) forming a third surface (e.g., the third surface (1641) of FIG. 6), a second layer (164b) forming a fourth surface (e.g., the fourth surface (1642) of FIG. 6), a third layer (164c) disposed between the first layer (164a) and the second layer (164b), and a fourth layer (164d) disposed between the second layer (164b) and the third layer (164c). Each of the plurality of layers (1640) may include a wiring layer (e.g., a copper layer). For example, the first layer (164a) may include a first ink layer (16401), a first plating layer (16402), and a first wiring layer (16403). For example, the second layer (164b) may include a second wiring layer (16413), a second plating layer (16414), and a second ink layer (16415). For example, the third layer (164c) may include a first adhesive layer (16404), a first material layer (16405), a second adhesive layer (16406), a third wiring layer (16407), and a second material layer (16408). For example, the fourth layer (164d) may include a fourth wiring layer (16409), a third adhesive layer (16410), a third material layer (16411), and a fourth adhesive layer (16412).

[0054] Each of the wiring layers (16403, 16407, 16409, 16413) can form at least one circuit that transmits and receives data or signals with a sensor unit (e.g., the sensor unit (161) of FIG. 4) and a first printed circuit board (e.g., the first printed circuit board (170) of FIG. 9). At least a portion of the wiring layers can be plated with a metal (e.g., copper, gold, or lead) and soldered by each of the plating layers (16402, 16414). Each of the ink layers (16401, 16415) can be formed to be applied to at least a portion of the wiring layers that are not plated to protect the wiring layers from an external environment. For example, the ink layers (16401, 16415) can include PSR (photo solder resist) ink. Each of the adhesive layers (16404, 16406, 16410, 16412) may be positioned and formed between the plurality of layers (1640) so that the wiring layers, the plating layers, and / or the ink layers are bonded to form a four-layer printed circuit board. For example, the adhesive layers (16404, 16406, 16410, 16412) may include a fiber composite material (e.g., prepreg). Each of the material layers (16405, 16408, 16411) may include a polymer compound (e.g., polyimide) having excellent heat resistance and strength. The shape and stacking order of the layers included in the plurality of layers (1640) are not limited to the above-described contents and may be formed in various shapes.

[0055] The second printed circuit board (163) connecting the sensor portion (161) of the button assembly (e.g., the button assembly (160) of FIG. 4) and the dome switch (e.g., the dome switch (167) of FIG. 4) may be formed as a four-layer printed circuit board including a plurality of layers (1640), so that the width parallel to the third direction (e.g., the -x-axis direction) of the second printed circuit board (163) and the button assembly (160) may be reduced. For example, the second printed circuit board (163) connecting the sensor portion (161) and the dome switch (167) may be formed as a single laminated substrate rather than a bent printed circuit board (e.g., a two-layer printed circuit board) including at least one layer, so that the width parallel to the x-axis may be reduced. For example, the second printed circuit board (163) may not include a separate support member (e.g., a reinforcing member including stainless steel) for supporting the printed circuit board, so that the width parallel to the x-axis may be reduced.

[0056] In one embodiment, the plurality of layers (1640) may be formed in a form in which at least some layers are excluded in order to reduce the thickness (e.g., thickness in the x-axis direction) of the second printed circuit board (163). For example, the plurality of layers (1640) may not include an adhesive layer or a material layer that may be arranged between the first layer (164a) and the third layer (164c) and between the second layer (164b) and the fourth layer (164d) in order to compensate for the thickness of the second printed circuit board (163). As an example, the second printed circuit board (163) may be configured with a minimum number of additional layers excluding the wiring layers (16403, 16407, 16409, 16413), so that the thickness (e.g., thickness in the x-axis direction) may be minimized.

[0057] In one embodiment, a flexible printed circuit board (e.g., the flexible printed circuit board (165) of FIG. 4) may be formed to extend from at least one layer of a plurality of layers (1640) of a rigid printed circuit board (164). For example, the flexible printed circuit board (165) may be formed such that two layers of the plurality of layers (1640) extend from a second portion (e.g., the second portion (1646) of FIG. 6) of the rigid printed circuit board (164). As an example, the flexible printed circuit board (165) may be formed such that a third layer (164c) and a fourth layer (164d) located in the second portion (1646) extend in a first direction from the second portion (1646). For example, a first extension portion (e.g., a first extension portion (1651) of FIG. 4) of a flexible printed circuit board (165) may extend in a first direction from a lead portion (e.g., a lead portion (1650) of FIG. 6) composed of a third layer (164c) and a fourth layer (164d) of a second-second portion (e.g., a second-second portion (1646_2) of FIG. 6).

[0058] FIG. 8 is a drawing showing a layout area of ​​a button assembly of an electronic device according to one embodiment.

[0059] FIG. 9 is a drawing showing an example of a layout area of ​​a button assembly according to one embodiment, as viewed from the rear of an electronic device.

[0060] Fig. 8 shows a view of an area (e.g., area A1 of Fig. 3) where a button assembly (e.g., button assembly (160) of Fig. 4) of a first housing (e.g., the first housing (110) of Fig. 1a) is arranged, as viewed from the -y axis. Reference numerals 901 and 902 of Fig. 9 show views of the area as viewed from the -z axis and as viewed obliquely to the -z axis.

[0061] With reference to FIGS. 8 and 9, in one embodiment, at least a portion of the button assembly (160) may be disposed within an interior space of the first housing (110) (e.g., the first space (1101) of FIG. 2). For example, the second printed circuit board (163) and the dome switch (e.g., the dome switch (167) of FIG. 4) may be disposed within the first space (1101). At least a portion of the button assembly (160) may be visible through a side surface of the first housing (110). For example, at least a portion of the sensor portion (161) may be visible outside the first housing (110) through a first opening (1132) formed in a side surface of the first housing (110) (e.g., the first side member (113)). For example, at least a portion of the first surface of the sensor portion (161) (e.g., the first surface (1611) of FIG. 6) may be positioned to protrude in the x-axis direction more than the first side member (113) so that it can be pressed by a user.

[0062] At least a portion of the sensor portion (161) may be formed to engage with a side surface (e.g., a first side member (113)) of the first housing (110). For example, a flange (1610) of the sensor portion (161) may extend further in the first direction and / or the second direction than the first side (1611) so as to engage with an inner surface (1133) (e.g., a surface facing the -x axis) of the first side member (113). By contacting the inner surface (1133) of the first side member (113) and the flange (1610) of the sensor portion (161), the sensor portion (161) may not be separated from the first housing (110).

[0063] The rigid printed circuit board (164) of the second printed circuit board (163) may be arranged parallel to the first side member (113), and the flexible printed circuit board (165) may be arranged to be bent at least once within the first space (1101) and connected to the first printed circuit board (170). For example, the rigid printed circuit board (164) may be arranged parallel to the sensor unit (161) on the x-axis. For example, the flexible printed circuit board (165) may have at least a portion (e.g., at least a portion of the first extension portion (1651) and at least a portion of the bend portion (1652)) disposed lower than the sensor portion (161) (e.g., in the z-axis direction), and at least a portion (e.g., at least a portion of the bend portion (1652), the third extension portion (1653), and the fourth extension portion (1654)) disposed higher than the sensor portion (161) (e.g., in the -z-axis direction). As an example, the bend portion (1652) may be formed to be bent one or more times within the first space (1101).

[0064] In one embodiment, when the sensor unit (161) is pressed in a third direction (e.g., in the -x-axis direction), stress (e.g., bending stress) may be generated in at least a portion of the bending unit (1652). In order to prevent damage to the bending unit (1652), the bending unit (1652) may be designed to be cushioned so that a stress less than a specified value is generated. For example, as described above, by simplifying the laminated structure of the second printed circuit board (163) (e.g., the plurality of layers (1640) of FIG. 7) to reduce the width in the x-axis direction, the area where the flexible printed circuit board (165) is positioned within the first space (1101) may be increased. As an example, when the sensor unit (161) is pressed, at least a portion of the bending unit (1652) may be bent in the third direction within the first space (1101), and the stress applied to the bending unit (1652) may be reduced. Due to the cushioning effect according to the bending of the bending portion (1652), the stress generated at the maximum bending point of the bending portion (1652) (e.g., the part bent at 90 degrees) may fall within the allowable stress range.

[0065] A first waterproofing member (180) and a bracket (190) may be disposed in a first space (1101) where a button assembly (160) is disposed. For example, a second opening (1102) leading to the first space (1101) may be formed in a portion adjacent to the first side member (113) of the first housing (110) (e.g., the first support member (1131) of FIG. 2), and the first waterproofing member (180) and the bracket (190) may be disposed through the second opening (1102). For example, the first waterproofing member (180) and the bracket (190) may be disposed on a flexible printed circuit board (164) (e.g., in the -z-axis direction). In one example, a plurality of holes (1135) may be formed in the first support member (1131) so that a fastening member such as a screw may be inserted therein.

[0066] At least a portion of the flexible printed circuit board (165) may be disposed adjacent to a metal portion of the first housing (110). For example, the bending portion (1652) may be disposed adjacent to an inner surface (1133) of the first side member (113) and / or the first display (130) (e.g., the first region (130a) of FIG. 1A). For example, at least a portion of the bending portion (1652) may be disposed adjacent to the inner surface (1133), and another portion may be disposed adjacent to the first display (130). In one example, when the sensor portion (161) is pressed in a third direction (e.g., in the −x-axis direction), the rigid printed circuit board (164) may be moved in the third direction, and the first extension portion (1651) and the bending portion (1652) may be bent in a direction in which they become closer to each other. One end of the bending portion (1652) in the first direction can be positioned closer to the inner surface (1133) or the first display (130) when the sensor portion (161) is pressed.

[0067] In one embodiment, since the bending portion (1652) is positioned adjacent to the inner side surface (1133), interference of a signal of the second printed circuit board (163) (e.g., a signal transmitted and received in at least one electrical circuit connecting the button assembly (160) and the first printed circuit board (170)) may occur due to the first side member (113) adjacent to the bending portion (1652). In order to mitigate the interference of the signal, the structure of the inner side surface (1133) adjacent to the bending portion (1652) may be changed, and this is described in FIGS. 12 to 14.

[0068] In one embodiment, since the bending portion (1652) is positioned adjacent to the first display (130), interference of the signal of the second printed circuit board (163) by the first display (130) may occur. To mitigate the signal interference, the structure of the first display (130) adjacent to the bending portion (1652) may be changed, and this is described in FIG. 15.

[0069] FIG. 10 is a drawing showing an example of a button assembly and a waterproof member according to one embodiment.

[0070] FIG. 11 is a drawing showing an example of a button assembly and bracket according to one embodiment.

[0071] Fig. 10 shows a view of an area where a first waterproof member (180) of a first housing (e.g., the first housing (110) of Fig. 1a) is placed, as viewed from the -z axis. Reference numerals 1101 and 1102 of Fig. 11 show a view of an area where a bracket (190) of the first housing (110) is placed, as viewed from the -z axis and a view of an area viewed obliquely to the -z axis.

[0072] Referring to FIGS. 8 to 11, in one embodiment, a first waterproof member (180) and a bracket (190) may be disposed on an upper portion (e.g., in the -z-axis direction) of a button assembly (e.g., the button assembly (160) of FIG. 4). For example, after the button assembly (160) is disposed in the first space (1101) of the first housing (110), the first waterproof member (180) may be disposed on at least a portion of a bending portion (1652) of a flexible printed circuit board (164) (e.g., in the -z-axis direction). An opening formed in the first waterproof member (180) may be passed through the bending portion (1652), and the bending portion (1652) may extend toward the first printed circuit board (170) on the first waterproof member (180) (e.g., in the -z-axis direction). The first waterproof member (180) may be formed so that, for example, the first space (1101) in which the first extension (1651) and the bending portion (1652) of the first housing (110) are arranged, and the second space in which the third extension (1653), the fourth extension (1654), and the first printed circuit board (170) are arranged are sealed to each other.

[0073] In one embodiment, with the button assembly (160) and the first waterproof member (180) disposed in the first housing (110), a bracket (190) may be coupled to the first housing (110). For example, the bracket (190) may be coupled to the first housing (110) through fastening members (191) inserted into a plurality of holes (1135) formed in at least a portion of the first housing (110) (e.g., the first support member (1131) of FIG. 2). For example, the bracket (190) may be formed to accommodate at least a portion of a flexible printed circuit board (165) (e.g., the bending portion (1652) or the third extension portion (1653)). For example, the button assembly (160) may not be free to move within the first housing (110) (e.g., within the first space (1101)) by the bracket (190) being coupled to at least a portion of the flexible printed circuit board (165). The button assembly (160) may be at least partially fixed to the first housing (110) by the first waterproofing member (180) and the bracket (190) being coupled to at least a portion of the button assembly (160).

[0074] FIGS. 12 to 14 are drawings showing an example of an inner shape adjacent to a button assembly of a side member according to one embodiment.

[0075] Reference numeral 1201 of Fig. 12 represents a form in which the first rear cover (e.g., the rear cover (114) of Fig. 1b) is excluded from the first housing (110), and reference numeral 1202 represents an enlarged view of area A2 of reference numeral 1201. Fig. 13 represents a cross-section of area A2 of Fig. 12 cut in a plane parallel to the xz plane, as viewed from the -y-axis direction. Fig. 14 represents a cross-section of area A2 of Fig. 12 cut in a plane parallel to the xz plane, as viewed obliquely to the z-axis.

[0076] With reference to FIGS. 12 to 14, in one embodiment, at least a portion of the first housing (110) may include an opening formed so as not to contact at least a portion of the button assembly (160). For example, the first housing (110) may include a third opening (1134) formed at a lower portion (e.g., in the z-axis direction) of a first space (e.g., the first space (1101) of FIG. 8) that accommodates a second printed circuit board (163). For example, the rigid printed circuit board (164) may be disposed in the first space (1101), and the flexible printed circuit board (165) may be disposed at least partially in the first space (1101) and the third opening (1134), respectively.

[0077] In one embodiment, the third opening (1134) may be formed from a contact surface (or, joining surface) of the first side member (113) and the first support member (1131). For example, an inner surface (1133) of the first side member (113) (e.g., a surface facing the -x axis) may be joined to one side surface (e.g., a surface facing the x axis) of the first support member (1131). The third opening (1134) may be formed by surfaces of the first side member (113) and the first support member (1131) that do not contact each other during the joining.

[0078] The third opening (1134) may be formed in a shape such that the end portion of the flexible printed circuit board (165) in the first direction does not come into contact with the first side member (113) and / or the first support member (1131). For example, the end portion (16511) of the flexible printed circuit board (165) in the first direction may be a part of a bending portion (1652) extending in the first direction from the first extension portion (1651). The end portion (16511) may be positioned lower (e.g., in the z-axis direction) than the inner surface (1133) of the first side member (113). Through the third opening (1134), the end portion (16511) can be prevented from contacting (or colliding) with the first side member (113) and the first support member (1131), thereby preventing damage (e.g., cracking) of the flexible printed circuit board (165). Through the third opening (1134), the end portion (16511) can be spaced apart from the first side member (113) and the first support member (1131) by a predetermined distance, and through the distance, interference (e.g., signal interference of the flexible printed circuit board (165)) that may be generated by the first side member (113) and / or the first support member (1131) can be alleviated.

[0079] In one embodiment, the third opening (1134) may be formed with a stepped shape at least partially so as not to come into contact with the flexible printed circuit board (165). For example, the third opening (1134) may include a first inner side (1133a), a second inner side (1133b), and a third inner side (1133c). The first inner side (1133a) and the third inner side (1133c) may be formed parallel to each other, and the second inner side (1133b) may be a curved surface formed to connect the first inner side (1133a) and the third inner side (1133c). For example, the third inner side (1133c) may have a shape that is more recessed in the x-axis direction than the first inner side (1133a). For example, the first inner side (1133a), the second inner side (1133b), and the third inner side (1133c) may be formed in a stepwise manner when viewed from the z-axis. For example, the third inner side (1133c), which is positioned to overlap the first extension (1651) of the flexible printed circuit board (165) in the x-axis direction, may be formed to have a shorter length from the side surface (e.g., the side facing the x-axis) of the first housing (110) compared to the first inner side (1133a). In one embodiment, the first inner side (1133a), the second inner side (1133b), and the third inner side (1133c) may be formed as a part of the inner side surface (1133) of the first side member (113). Alternatively, in one embodiment, at least one of the first inner side (1133a), the second inner side (1133b), or the third inner side (1133c) may be formed as part of the first support member (1131).

[0080] The width of the third opening (1134) in the third direction may be set to prevent contact between the end (16511) and the inner surface (1133) in the first direction of the flexible printed circuit board (165). For example, the width of the area through which the end (16511) of the third opening (1134) passes in the third direction may be formed to be larger than the width of the remaining area in the third direction. For example, the fifth width (W5) of the third inner surface (1133c) in the third direction may be formed to be larger than the sixth width (W6) of the first inner surface (1133a) in the third direction. For example, the width of the second printed circuit board (163) in the third direction may be reduced as the second printed circuit board (163) is formed as a four-layer printed circuit board including a plurality of layers (e.g., a plurality of layers (1640) of FIG. 7). As the width of the second printed circuit board (163) (or, rigid printed circuit board (164)) in the third direction is reduced, the region where the first extension portion (1651) and the bend portion (1652) of the flexible printed circuit board (165) are positioned may also move in the x-axis direction. For example, a step structure composed of a first inner side surface (1133a), a second inner side surface (1133b), and a third inner side surface (1133c) may be formed to avoid positioning at least a portion (e.g., the end portion (16511)) of the first extension portion (1651) or the bend portion (1652) on the first side member (113) (e.g., in the -z-axis direction).

[0081] In one embodiment, a second waterproofing member (181) (or adhesive member, waterproofing tape) may be disposed inside the first housing (110). For example, the second waterproofing member (181) may be disposed on at least a portion of the first side member (113) and / or at least a portion of the first support member (1131). For example, the second waterproofing member (181) may be attached to the inside of the first side member (113) of the first housing (110) (or an edge of the first housing (110). For example, the second waterproofing member (181) may be configured to prevent fluid flowing in from the outside of the first housing (110) from diffusing to electrical components mounted inside the first housing (110) (e.g., electrical components disposed on the first printed circuit board (170) of FIG. 9). The second waterproofing member (181) may be formed in a shape corresponding to the shape of the first housing (110). For example, at least a portion of the second waterproofing member (181) may be formed in a shape corresponding to the stepped shape of the inner surface (1133) (e.g., a stepped structure composed of the first inner surface (1133a), the second inner surface (1133b), and the third inner surface (1133c)). For example, the second waterproofing member (181) may be placed in an area excluding an area corresponding to the third opening (1134) so ​​as not to come into contact with the second printed circuit board (163).

[0082] FIG. 15 is a drawing showing an example of a display and support member of an electronic device according to one embodiment.

[0083] FIG. 15 schematically illustrates a portion of an electronic device (e.g., an electronic device (100) of FIG. 1A) disposed adjacent to a first side member (e.g., a first side member (113) of FIG. 1A) of a first display (e.g., a first display (130) of FIG. 1A).

[0084] Referring to FIG. 15, in one embodiment, a first display (130) of an electronic device (e.g., the electronic device (100) of FIG. 1A) may be formed by stacking a plurality of configurations from the bottom toward the top in a first direction (e.g., toward the -z-axis). For example, the first display (130) may include a first adhesive member (1307) (e.g., an optically transparent adhesive), a polarizing film (1306), a second adhesive member (1305) (e.g., an optically transparent adhesive), a display panel (1304), a third adhesive member (1303) (e.g., an optically transparent adhesive), a polyimide film (1302), a fourth adhesive member (1301), and a third support member (1300) disposed on a cover glass (1308) (e.g., in the -z-axis direction). The plurality of components (1300, 1301, 1302, 1303, 1304, 1305, 1306, 1307, 1308) of the first display (130) may be arranged to at least partially overlap in a first direction. The third support member (1300) may be formed to support at least some of the plurality of components in the first direction. At least some of the first display (130) may be arranged adjacent to a second printed circuit board (e.g., the second printed circuit board (163) of FIG. 4). For example, the third support member (1300) positioned at the top (e.g., the end in the -z-axis direction) of the first display (130) may be arranged adjacent to the second printed circuit board (163). For example, the third support member (1300) may be positioned adjacent to an end of the second printed circuit board (163) in the first direction (e.g., the end (16511) of FIG. 14). In one embodiment, the third support member (1300) may be formed integrally with the first support member (e.g., the first support member (1131) of FIG. 2). For example, the third support member (1300) may correspond to a portion of the first support member (1131) that supports the first display (130) in the first direction.

[0085] In one embodiment, the third support member (1300) may be formed in a form in which at least a portion thereof is removed compared to other components of the first display (130) (e.g., the polyimide film (1302), the third adhesive member (1303), or the display panel (1304)) to mitigate interference generated in the second printed circuit board (163). For example, the third support member (1300) may include a step formed parallel to the x-axis at one end adjacent to the second printed circuit board (163) (e.g., the bending portion (1652) of FIG. 4). By forming the step, the end portion (16511) of the second printed circuit board (163) in the first direction and the other components of the first display (130) may be spaced apart by a specified distance (e.g., a distance set so as to prevent interference of signals). For example, the third support member (1300) may be formed so that at least a portion thereof is stepped in the third direction so that the first display (130) is spaced apart from the end (16511) of the second printed circuit board (163) in the first direction by a specified distance or more. For example, at least a portion of one end (e.g., an end in the x-axis direction) of the third support member (1300) adjacent to the end (16511) of the second printed circuit board (163) may be formed so as to be positioned in the -x-axis direction compared to one end (e.g., an end in the x-axis direction) of the other components. For example, one end of the third support member (1300) may be spaced apart from one end of the other components by a predetermined distance (D1). The distance in the first direction between at least a portion (e.g., the end (16511)) of the second printed circuit board (163) and the first display (130) may be increased by the distance (D1).For example, interference of a signal (e.g., a signal of the second printed circuit board (163)) that may be generated when at least a portion of the bending portion (e.g., the bending portion (1652) of FIG. 8) is positioned on the first display (130) (e.g., in the -z-axis direction) can be reduced by having the third support member (1300) spaced apart in the third direction from the end (16511) of the bending portion (1652) in the first direction. Alternatively, for example, when the third support member (1300) is spaced apart from the other configurations by the distance (D1), even when the button assembly (e.g., the button assembly (160) of FIG. 4) is pressed, the bending portion (1652) does not come into contact with the first display (130), thereby preventing damage to the second printed circuit board (163).

[0086] FIG. 16 is a block diagram of an electronic device within a network environment according to various embodiments.

[0087] Referring to FIG. 16, in one embodiment, in a network environment (1600), an electronic device (1601) (e.g., the electronic device (100) of FIG. 1A) may communicate with an electronic device (1602) via a first network (1698) (e.g., a short-range wireless communication network), or may communicate with at least one of an electronic device (1604) or a server (1608) via a second network (1699) (e.g., a long-range wireless communication network).

[0088] The processor (1620) may control at least one other component (e.g., a hardware or software component) of the electronic device (1601) connected to the processor (1620) by executing, for example, software (e.g., a program (1640)), and may perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (1620) may store commands or data received from other components (e.g., a sensor module (1676) or a communication module (1690)) in a volatile memory (1632), process the commands or data stored in the volatile memory (1632), and store result data in a non-volatile memory (1634).

For example, when the electronic device (1601) includes the main processor (1621) and the secondary processor (1623), the secondary processor (1623) may be configured to use less power than the main processor (1621) or to be specialized for a given function. The secondary processor (1623) may be implemented separately from the main processor (1621) or as a part thereof.

[0089] The auxiliary processor (1623) may control at least a portion of functions or states associated with at least one component (e.g., the display module (1660), the sensor module (1676), or the communication module (1690)) of the electronic device (1601), for example, on behalf of the main processor (1621) while the main processor (1621) is in an inactive (e.g., sleep) state, or together with the main processor (1621) while the main processor (1621) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1623) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1680) or a communication module (1690)). In one embodiment, the auxiliary processor (1623) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (1601) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (1608)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above.

[0092] The input module (1650) can receive commands or data to be used in a component of the electronic device (1601) (e.g., a processor (1620)) from an external source (e.g., a user) of the electronic device (1601). The input module (1650) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button) (e.g., a button assembly (160) of FIG. 4), or a digital pen (e.g., a stylus pen).

[0093] The audio output module (1655) can output audio signals to the outside of the electronic device (1601). The audio output module (1655) can include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

The display module (1660) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (1660) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0095] The audio module (1670) can convert sound into an electrical signal, or vice versa. According to one embodiment, the audio module (1670) can acquire sound through the input module (1650), output sound through the sound output module (1655), or an external electronic device (e.g., electronic device (1602)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (1601).

[0096] The sensor module (1676) can detect the operating status (e.g., power or temperature) of the electronic device (1601) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (1676) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0097] The interface (1677) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (1601) with an external electronic device (e.g., the electronic device (1602)).

[0103] The communication module (1690) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (1601) and an external electronic device (e.g., electronic device (1602), electronic device (1604), or server (1608)), and the performance of communication through the established communication channel. The communication module (1690) may operate independently from the processor (1620) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (1690) may include a wireless communication module (1692) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (1694) (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external electronic device (1604) via a first network (1698) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (1699) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a local area network or a wide area network)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (1692) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (1696) to identify or authenticate the electronic device (1601) within a communication network such as the first network (1698) or the second network (1699).

[0104] The wireless communication module (1692) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency communications (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (1692) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate.

In one embodiment, the antenna module (1697) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (1698) or the second network (1699), may be selected from the plurality of antennas by, for example, the communication module (1690). A signal or power may be transmitted or received between the communication module (1690) and an external electronic device via the selected at least one antenna. In one embodiment, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (1697).

[0106] According to various embodiments, the antenna module (1697) may form a mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0107] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0108] According to one embodiment, commands or data may be transmitted or received between the electronic device (1601) and an external electronic device (1604) via a server (1608) connected to a second network (1699). Each of the external electronic devices (1602 or 1604) may be the same or a different type of device as the electronic device (1601). According to one embodiment, all or part of the operations executed in the electronic device (1601) may be executed in one or more of the external electronic devices (1602, 1604, or 1608). For example, when the electronic device (1601) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (1601) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (1601). The electronic device (1601) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (1601) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In one embodiment, the external electronic device (1604) may include an Internet of Things (IoT) device. The server (1608) may be an intelligent server utilizing machine learning and / or a neural network.In one embodiment, an external electronic device (1604) or server (1608) may be included within the second network (1699). The electronic device (1601) may be applied to intelligent services (e.g., smart homes, smart cities, smart cars, or healthcare) based on 5G communication technology and IoT-related technology.
