[0042] FIG. 1 is a diagram illustrating an electronic device that emits sound according to one embodiment.

[0043] Referring to FIG. 1, an electronic device (101) according to one embodiment may include a foldable housing (400), a hinge assembly (e.g., the hinge device (240, 240-1) of FIG. 3 or the hinge device (340, 340-1) of FIG. 5), a flexible display (500) (e.g., the first display (230) of FIG. 2A or the first display (330) of FIG. 4A), and a speaker (e.g., 700 of FIG. 7).

[0044] In an electronic device (101) according to one embodiment, the foldable housing (400) may include a first housing (410) (e.g., the first housing (210) of FIG. 2A or the first housing (310) of FIG. 4A) and a second housing (420) (e.g., the second housing (220) of FIG. 2A or the second housing (320) of FIG. 4A).

[0045] In an electronic device (101) according to one embodiment, a lateral side of the first housing (410) may include a first side (413), a second side (416), and a third side (419).

[0046] In an electronic device (101) according to one embodiment, the side surfaces of the second housing (420) may include a fourth side surface (423), a fifth side surface (426), and a sixth side surface (429).

[0047] In an electronic device (101) according to one embodiment, in a folded state of the foldable housing (400), the first side (413) and the fourth side (423) may correspond to each other, the second side (416) and the fifth side (426) may correspond to each other, and the third side (419) and the sixth side (429) may correspond to each other.

[0048] A foldable housing (400) of an electronic device (101) according to one embodiment may include a first front member (610) disposed in a first housing (410) along an edge of a flexible display (500) and a second front member (620) disposed in a second housing (420) along an edge of the flexible display (500). According to one embodiment, for example, the first front member (610) and / or the second front member (620) may be formed of an elastic material.

[0049] According to one embodiment, the first front member (610) may be connected to the first side (413), the second side (416), and the third side (419). The first front member (610) according to one embodiment may be formed along an edge of the first display portion (503) and may be arranged in a direction from the side of the first housing (410) (e.g., the first side (413), the second side (416), and the third side (419)) toward the first display portion (503). According to one embodiment, the first front member (610) may be formed separately from the side of the first housing (410) (e.g., the first side (413), the second side (416), and the third side (419)) and may be coupled to the side of the first housing (410), but is not limited thereto. For example, the first front member (610) may be formed integrally with the side surface of the first housing (410) and may be positioned to extend from the side surface of the first housing (410).

[0050] According to one embodiment, the second front member (620) may be connected to the fourth side (423), the fifth side (426), and the sixth side (429). According to one embodiment, the second front member (620) may be formed along an edge of the second display portion (506) and may be arranged in a direction from the side of the second housing (420) (e.g., the fourth side (423), the fifth side (426), and the sixth side (429)) toward the second display portion (506). According to one embodiment, the second front member (620) may be formed separately from the side of the second housing (420) (e.g., the fourth side (423), the fifth side (426), and the sixth side (429)) and may be coupled to the side of the second housing (420), but is not limited thereto. For example, the second front member (620) may be formed integrally with the side surface of the second housing (420) and may be positioned to extend from the side surface of the second housing (420).

[0051] In an electronic device (101) according to one embodiment, the first front member (610) may include a first sound emitting area (710). For example, the first sound emitting area (710) may be formed at a position corresponding to a portion adjacent to a speaker (e.g., 700 of FIG. 7) among the side surfaces of the first housing (410). For example, the first sound emitting area (710) may be positioned adjacent to the first side surface (413) of the first housing (410). For example, the first sound emitting area (710) may be recessed toward the interior of the electronic device (101) (e.g., in the -z-axis direction) and may include a first recessed area (715) (e.g., 715 of FIG. 6) including at least one emitting hole (713). For example, the first sound emission region (710) may include a border region (714) (e.g., 714 in FIG. 6) surrounding the first recess region (715). For example, the border region (714) may include a first lateral region (e.g., 718 in FIG. 9), a second lateral region (e.g., 719 in FIG. 9), and a rear region (717 in FIG. 9). The border region (714) will be described later with reference to FIG. 9.

[0052] For example, the first recessed area (715) may be formed by cutting a portion of the first front member (610) or by injection molding. For example, one side (e.g., identification number 1 in FIG. 6) of the first recessed area (715) may be connected to the first side (413) of the first housing (410), and a plurality of discharge holes (713) may be arranged on the other side (e.g., identification number 2 in FIG. 6) of the first recessed area (715). For example, the first recessed area (715) may form a sloped surface with one side (e.g., identification number 1 in FIG. 6) facing toward the first side (413) of the first housing (410). The first recessed area (715) will be described later with reference to FIG. 12.

[0053] In an electronic device (101) according to one embodiment, a speaker (e.g., 700 of FIG. 7) may be placed inside a first housing (410). For example, the speaker (e.g., 700 of FIG. 7) may be placed adjacent to a first side (413) of the first housing (410). For example, the speaker (e.g., 700 of FIG. 7) may be placed below a flexible display (500).

[0054] In an electronic device (101) according to one embodiment, an acoustic path (e.g., 705 of FIG. 7) may be formed in a space between a speaker (e.g., 700 of FIG. 7) and a flexible display (500). For example, the speaker (e.g., 700 of FIG. 7) may be connected to a plurality of emission holes (713) through an acoustic path (e.g., 705 of FIG. 7) formed inside a foldable housing (400). For example, the acoustic path (e.g., 705 of FIG. 7) formed inside the foldable housing (400) may be formed by an internal space surrounded by at least a portion of a first side (413) of the first housing (410), the flexible display (500), or the support member (520) (e.g., 520 of FIG. 7). For example, sound output from a speaker (e.g., 700 in FIG. 7) may sequentially pass through a sound path (e.g., 705 in FIG. 7) and a plurality of emission holes and be emitted to the outside of the electronic device (101). The sound path (e.g., 705 in FIG. 7) formed inside the foldable housing (400) will be described later in FIG. 7.

[0055] In an electronic device (101) according to one embodiment, a hinge assembly (e.g., hinge device (240, 240-1) of FIG. 3 or hinge device (340, 340-1) of FIG. 5) can rotatably connect a first housing (410) and a second housing (420).

[0056] In an electronic device (101) according to one embodiment, a flexible display (500) can be arranged across a first housing (410) and a second housing (420).

[0058] The electronic device (200) of FIGS. 2A, 2B and 2C may correspond to the electronic device (101) of FIG. 1.

[0059] Referring to FIGS. 2A, 2B, and 2C, the electronic device (200) may include a first housing (210) (e.g., a first housing structure) including a first side member (213) (e.g., a side bezel) and a second housing (220) (e.g., a second housing structure) including a second side member (223) (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 (240, 240-1) (e.g., a hinge module or a hinge structure). For example, the first housing (210) and the second housing (220) may be configured as a foldable housing (e.g., a housing structure). For example, the electronic device (200) may include a first display (230) (e.g., a flexible display, a foldable display, or a main display) arranged to be supported by a first housing (210) and a second housing (220). For example, the first housing (210) may include a first side (211) and a second side (212) facing in an opposite direction (e.g., a -z-axis direction) of the first side (211). For example, the second housing (220) may include a third side (221) and a fourth side (222) facing in an opposite direction (e.g., a -z-axis direction) of the third side (221). For example, the first housing (210) may include a first rear cover (214) coupled with a first side member (213). For example, the second housing (220) may include a second rear cover (224) coupled with a second side member (223). For example, when the electronic device (200) is in a fully unfolded first state (e.g., an unfolded state or an unfolded state), the first side (211) and the third side (221) may be operated so that they face substantially the same direction (e.g., a z-axis direction). For example, when the electronic device (200) is in a fully folded second state (e.g., a folded state or a folded state), the first side (211) and the third side (221) may face each other or face opposite directions.For example, the electronic device (200) may be operated to maintain a third state (e.g., an intermediate state) between the first state and the second state.

[0060] According to one embodiment, the electronic device (200) may include a receiver (201), at least one sensor module (204) (e.g., an ambient light sensor), and / or at least one first camera module (205) (e.g., a UDC, under display camera) disposed on a first side (211) of the first housing (210). For example, the electronic device (200) may include at least one key (206) disposed on a first side member (213). For example, the electronic device (200) may include a second display (231) (e.g., a sub-display), at least one second camera module (208), and / or a flash (209) disposed on a second side (212) of the first housing (210) (e.g., a first rear cover (214)). For example, the second display (231) may be disposed to be visible from the outside through at least a portion of the first rear cover (214). For example, the electronic device (200) may include a speaker (202), a microphone (203), or a connector port (207) arranged on the second side member (223). At least some of the aforementioned components may be arranged in the first housing (210) and / or the second housing (220).

[0061] According to one embodiment, the first display (230) (e.g., a flexible display) may include a first region (230a) (e.g., a first planar portion) corresponding to at least a portion of the first surface (211), a second region (230b) (e.g., a second planar portion) corresponding to at least a portion of the third surface (221), and a third region (230c) (e.g., a flexible portion) connecting the first region (230a) and the second region (230b) and allowing the electronic device (200) to be deformed in a second state (e.g., a folded state) and / or a third state (e.g., an intermediate state). For example, the third region (230c) may be positioned at a position that at least partially overlaps at least one hinge device (240, 240-1) when the first display (230) is viewed from above (e.g., in the z-axis direction). For example, the first display (230) may be arranged so that it is not visible from the outside in the second state by having the first side (211) and the third side (221) face each other (e.g., inward-fold type). For example, the first display (230) may be arranged so that it is visible from the outside in the second state by having the first side (211) and the third side (221) face each other in opposite directions (e.g., outward-fold type).

[0062] FIG. 3 is an exploded perspective view of a portion of the electronic device of FIGS. 2A, 2B, and 2C including a hinge device according to one embodiment.

[0064] Referring to FIG. 3, the electronic device (200) may include at least one hinge device (240, 240-1) (e.g., a hinge module or a hinge structure) connecting the first housing (210) and the second housing (220) under the first display (230) (e.g., in the -z-axis direction). For example, the at least one hinge device (240, 240-1) may include a first hinge device (240) and a second hinge device (240-1) spaced apart from the first hinge device (240) along a direction parallel to the folding axis (F) (e.g., in the ±y-axis direction). For example, at least one hinge device (240, 240-1) may be supported by a first support member (2131) extending from the first side member (213) to the first space (3101) of the first housing (210) and a second support member (2231) extending from the second side member (223) to the second space (3201) of the second housing (220). For example, at least one hinge device (240, 240-1) may be arranged between the first housing (210) and the second housing (220) so as to be invisible from the outside through a hinge housing (250) (e.g., a hinge cover).

[0065] According to one embodiment, the first hinge device (240) may include a first rotation member (241) (e.g., a first arm or a first rotator) disposed on a first support member (2131) of the first housing (210), a second rotation member (242) (e.g., a second arm or a second rotator) disposed on a second support member (2231) of the second housing (220), and a gear assembly (243) connected to the first rotation member (241) and the second rotation member (242) such that the first housing (210) and the second housing (220) rotate symmetrically with respect to each other. For example, the gear assembly (243) may include a plurality of gears (e.g., spur gears and / or worm gears) gear-coupled with respect to one another. For example, the gear assembly (243) may include a cam coupling structure for urging the first housing (210) and the second housing (220) 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 (240-1) may be substantially symmetrical with respect to the first hinge device (240), or may have a configuration that is substantially the same.

[0066] According to one embodiment, the electronic device (200) may be coupled with at least one hinge device (240, 240-1) and may include at least one detent module (244) for providing a stopping sensation at various angles. For example, at least one hinge device (240, 240-1) and / or the detent module (244) may form substantially the same plane as the first support member (2131) and the second support member (2231) when the electronic device (200) is in the first state. For example, the second hinge device (240-1) may be substantially symmetrical with the first hinge device (240) or may have a substantially identical configuration.

[0071] According to one embodiment, the first display (330) (e.g., a flexible display) may include a first region (330a) (e.g., a first planar portion) corresponding to at least a portion of the first surface (311), a second region (330b) (e.g., a second planar portion) corresponding to at least a portion of the third surface (321), and a third region (330c) (e.g., a flexible portion) connecting the first region (330a) and the second region (330b) and allowing the electronic device (300) to be deformed in a second state (e.g., a folded state) and / or a third state. For example, the third region (330c) may be positioned to at least partially overlap at least one hinge device (340, 340-1) when the first display (330) is viewed from above (e.g., in the z-axis direction). For example, the first display (330) may be arranged so that it is not visible from the outside in the second state by having the first side (311) and the third side (321) face each other (e.g., inward-fold type). For example, the first display (330) may be arranged so that it is visible from the outside in the second state by having the first side (311) and the third side (321) face each other in opposite directions (e.g., outward-fold type).

[0072] FIG. 5 is an exploded perspective view of a portion of the electronic device of FIGS. 4A, 4B, and 4C including a hinge device according to various embodiments of the present disclosure.

[0073] The electronic device (300) of FIG. 5 can correspond to the electronic device (101) of FIG. 1.

[0074] Referring to FIG. 5, the electronic device (300) may include at least one hinge device (340, 340-1) (e.g., a hinge module or a hinge structure) connecting the first housing (310) and the second housing (320) under the first display (330) (e.g., in the -z-axis direction). For example, the at least one hinge device (340, 340-1) may include a first hinge device (340) and a second hinge device (340-1) spaced apart from the first hinge device (340) along a direction parallel to the folding axis (F) (e.g., in the ±y-axis direction). For example, at least one hinge device (340, 340-1) may be supported by a first support member (3131) extending from the first side member (313) to the first space (3101) of the first housing (310) and a second support member (3231) extending from the second side member (323) to the second space (3201) of the second housing (320). For example, at least one hinge device (340, 340-1) may be arranged between the first housing (310) and the second housing (320) so as to be invisible from the outside through a hinge housing (350) (e.g., a hinge cover).

[0075] According to one embodiment, the first hinge device (340) may include a first rotation member (341) (e.g., a first arm or a first rotator) disposed on a first support member (3131) of the first housing (310), a second rotation member (342) (e.g., a second arm or a second rotator) disposed on a second support member (3231) of the second housing (320), and a gear assembly (343) connected to the first rotation member (341) and the second rotation member (342) such that the first housing (310) and the second housing (320) rotate symmetrically with respect to each other. For example, the gear assembly (343) may include a plurality of gears (e.g., spur gears and / or worm gears) gear-coupled with respect to one another. For example, the gear assembly (343) may include a cam coupling structure for urging the first housing (310) and the second housing (320) 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 (340-1) may have substantially the same configuration as the first hinge device (340).

[0076] According to one embodiment, the electronic device (300) may include a first hinge plate (361) connected to a first support member (3131) and / or a first rotation member (341). The electronic device (300) may include a second hinge plate (362) connected to a second support member (3231) and / or a second rotation member (342). For example, at least one hinge device (340, 340-1), the first rotation member (341), the second rotation member (342), the first hinge plate (361), and the second hinge plate (362) may form substantially the same plane as the first support member (3131) and the second support member (3231) when the electronic device (300) is in a first state. For example, the second hinge device (340-1) may be substantially symmetrical with the first hinge device (340) or may have a substantially identical configuration.

[0077] Fig. 6 is a perspective view showing the periphery of a first sound emission area (710) of an electronic device (101) according to one embodiment. Fig. 7 is a perspective view showing the periphery of a first sound emission area (710) of an electronic device (101) according to one embodiment with a flexible display (500) removed.

[0078] Referring to FIGS. 6 and 7, a first front member (610) of an electronic device (101) according to one embodiment may include a first sound emission area (710) for emitting sound output from a speaker (700) of the electronic device (101). The first sound emission area (710) may be formed at a position corresponding to a portion adjacent to the speaker (700) among the side surfaces of the first housing (410). The first sound emission area (710) may include a first recess area (715) sunken toward the inside of the electronic device (101) and a border area (714) surrounding the first recess area (715).

[0079] For example, at least one emission hole (713) connected to the sound path (705) may be formed in the first recessed region (715). The border region (714) may be a portion extending from the surface of the first front member (610) and may be formed so as not to be sunken toward the inside of the electronic device (101). For example, the border region (714) may include a first side region (e.g., 718 of FIG. 9), a second side region (e.g., 719 of FIG. 9), and a rear region (717 of FIG. 9).

[0080] For example, in the unfolded state of the foldable housing (400), the plurality of emission holes (713) connected to the sound path (705) may be configured so that the sound output from the speaker (700) is emitted from inside the first housing (410) toward the front of the first housing (410). For example, the plurality of emission holes (713) connected to the sound path (705) may be formed in the first front member (610). For example, the plurality of emission holes (713) connected to the sound path (705) may be arranged along the longitudinal direction of the first front member (610) (e.g., the x-axis direction of FIG. 1).

[0081] According to one embodiment, the first front member (610) of the electronic device (101) may be in partial contact with the second front member (620) in correspondence with the second front member (620) in the folded state of the foldable housing (400).

[0082] In one embodiment, the electronic device (101) has a first sound emission port (716) (e.g., 716 of FIG. 12) that is opened in a first direction by a first recessed area (715) of a first sound emission area (710) in a folded state of the foldable housing (400) and is formed between the first front member (610) and the second front member, and sound output from the speaker (700) can be emitted to the outside of the electronic device (101) through the emission port (716). For example, in the folded state of the foldable housing (400), the first front member (610) and the second front member (620) can prevent sound output from the speaker (700) from being emitted to a portion where the first front member (610) and the second front member (620) come into contact. For example, the edge area (714) of the first sound emission area (710) may be in contact with the second front member (620) in the folded state of the foldable housing (400), and the first recess area (715) of the first sound emission area (710) may be spaced apart from the second front member (620). Accordingly, sound output from the speaker (700) and emitted through the plurality of emission holes (713) may be emitted toward the side of the electronic device (101).

[0083] For example, in the folded state of the foldable housing (400), the sound output from the speaker (700) can be sequentially emitted to the outside through the sound path (705), the plurality of emission holes (713), and the first recessed area (715). For example, in the folded state of the foldable housing (400), the first recessed area (715) can be spaced apart from the second front member (620), and the plurality of emission holes (713) can be formed in a shape that has an incline toward the spaced apart space. For example, in the folded state of the foldable housing (400), since the first recessed area (715) is spaced apart from the second front member (620), the sound output from the speaker (700) can be emitted in the first direction rather than the front of the first housing (410) through the plurality of emission holes (713). For example, when the foldable housing (400) is in a folded state, if the sound output from the speaker (700) is emitted toward the front of the first housing (410), the sound may be blocked by the second front member (620), resulting in sound reduction and sound vibration in a specific frequency band. For example, the first recessed area (715) may serve as a passage connecting the plurality of emission holes (713) and the outside when the foldable housing (400) is in a folded state.

[0084] Fig. 8 is a front view showing the periphery of a first sound emission area (710) of an electronic device (101) according to one embodiment. Fig. 9 is an enlarged view of the first sound emission area (710) of Fig. 8.

[0085] Referring to FIGS. 8 and 9, in an electronic device (101) according to one embodiment, the first sound emission area (710) may be positioned adjacent to the first side (413). For example, in a folded state of the foldable housing (400), the first sound emission area (710) may be formed on the first front member (610) adjacent to the first side (413) of the first housing (410) and the fourth side (423) of the second housing (420).

[0086] In an electronic device (101) according to one embodiment, one side (1) of the first recessed area (715) may be connected to at least a portion of an edge of the first side (413). According to one embodiment, a plurality of emission holes (713) may be formed in the first recessed area (715) at a portion adjacent to the other side (2) of the first recessed area (715). For example, the first recessed area (715) may be formed by cutting at least a portion of the first front member (610), or the first front member (610) including the first recessed area (715) may be formed by, for example, injection molding. For example, the first recessed area (715) may be cut so that the surface has a gentle slope. For example, the plurality of emission holes (713) may be formed by cutting at least a portion of the first front member (610) so as to face the first side (413).

[0087] Fig. 10 is a front view of Fig. 8 with the flexible display (500) removed. Fig. 11 is a front view of Fig. 10 with the support member (520) removed.

[0088] Referring to FIGS. 10 and 11, in an electronic device (101) according to one embodiment, a support member (520) that supports at least one electronic component (e.g., a light sensor, a front camera (510)) may be placed inside a first housing (410). For example, a speaker (700) may be placed adjacent to a first side (413) of the first housing (410) on one side of the front camera (510). For example, a flexible display (500) in the first housing (410) may be supported at the rear by the support member (520).

[0089] In an electronic device (101) according to one embodiment, the sound path (705) may be formed by an internal space surrounded by a first side (413) of the first housing (410), the flexible display (500), or at least a portion of the support member (520). For example, one side of the internal space formed on the inside of the first front member (610) and the flexible display (500) may be connected to a speaker (700), and the other side of the internal space may be connected to a plurality of emission holes (713). For example, the support member (520) may have a space connected from the speaker (700) to the plurality of emission holes (713), and the sound path (705) may include a space provided in the support member (520). For example, a space provided in the support member (520) may be surrounded by the first side (413) of the first housing (410) and the flexible display (500) to form an acoustic path (705). For example, the acoustic path (705) may allow sound output from the speaker (700) to be reflected by the support member (520), the first side (413), and the flexible display (500) or guided toward a plurality of emission holes (713) so as to be emitted through the plurality of emission holes (713). For example, an internal space surrounded by the support member (520), the first side (413), or the flexible display (500) may be formed at a position corresponding to the speaker (700) and the plurality of emission holes (713).

[0090] FIG. 12 is a cross-sectional view showing a cross-section taken in the C-C' direction of FIG. 8 in a folded state of a foldable housing (400) according to one embodiment.

[0091] For example, referring to FIG. 2C, FIG. 12 may be a cross-section taken in the A-A' direction for part a in the folded state of the electronic device (101) of FIG. 2C.

[0092] For example, referring to FIG. 4C, FIG. 12 may be a cross-section taken in the B-B' direction with respect to part b in the folded state of the electronic device (101) of FIG. 4C.

[0093] Referring to FIGS. 2C, 4C, and 12, in an electronic device (101) according to one embodiment, at least a portion of a first recessed area (715) of a first front member (610) may be inclined toward the first side (413). For example, the first recessed area (715) may amplify sound emitted to the outside through the inclined portion. For example, the first recessed area (715) may be formed by cutting at least a portion of the first front member (610). Alternatively, the first front member (610) including the first recessed area (715) may be formed by, for example, injection molding. For example, the first recessed area (715) may be formed to have an inclined surface in a direction from a first direction (e.g., an opposite direction of the plurality of emission holes (713)) toward the first side (413) of the first housing (410). For example, one side of the inclined surface formed in the first recessed area (715) may be connected to the boundary of the plurality of emission holes (713), and the other side of the inclined surface formed in the first recessed area (715) may be connected to at least a portion of the first housing (410). For example, the depth of one side (1) near the first side (413) of the first recessed area (715) may be formed to be greater than the depth of the other side (2) of the first recessed area (715). For example, one side (1) and / or the other side (2) of the first recessed area (715) may be formed to have a depth of approximately 0.1 mm to 0.3 mm. For example, the width of the sound emission port (716) may be formed to increase toward the first side (413) of the electronic device (101). For example, the size of sound emitted to the outside of the electronic device (101) can be amplified by the first recess area (715).

[0094] For example, in the folded state of the foldable housing (400), sound output from the speaker (700) can be sequentially emitted to the outside through the sound path (705), the plurality of emission holes (713) and the inclined surface of the first recess area (715) formed inside the foldable housing (400).

[0095] Referring to FIG. 12, in an electronic device (101) according to one embodiment, the second front member (620) may include a second sound emitting area (720). For example, the second sound emitting area (720) may be formed at a position corresponding to a portion of a side surface of the second housing (420) adjacent to the speaker (700) when the foldable housing (400) is in a folded state. For example, the second sound emitting area (720) may be positioned adjacent to the fourth side surface (423) of the second housing (420). For example, the second sound emitting area (720) may be in partial contact with the first front member (610) when the foldable housing (400) is in a folded state. For example, the second sound emitting area (720) may be in partial contact with the first sound emitting area (710) when the foldable housing (400) is in a folded state.

[0096] FIG. 13 is a drawing for explaining a shape and corresponding frequency characteristics that can be applied to an acoustic emission port (716) of an electronic device (101) according to one embodiment.

[0097] An electronic device (101) according to one embodiment can amplify sound output from a speaker (700) by forming a first recessed area (715) spaced apart from a second front member (620) when the foldable housing (400) is in a folded state, and an emission port (716) open in a first direction to form a horn speaker (700) shape. For example, a horn speaker may be shaped like a trumpet-shaped horn, and its basic structure may be configured such that a thin diaphragm is arranged at the rear so that sound generated from the diaphragm is amplified and output from the inlet to the neck and the outlet. For example, a horn speaker may determine a frequency range to be amplified depending on the cross-sectional area and length of the horn, and an impedance change may appear differently depending on the shape of the horn. For example, a horn speaker may improve the efficiency and quality of sound emitted depending on the shape of the horn, and may improve the response in a specific frequency range. For example, a horn speaker can amplify the sound emitted and improve the sound quality by having a shape that widens from the inlet to the outlet. For example, in a horn speaker, the shape of the horn can have a hyperbolic shape, an exponential shape, and a conical shape. According to one embodiment, at least a portion of an emission port (716) formed by the first recessed area (715) and the second front member (620) can have at least one shape among a hyperbolic shape, an exponential shape, and / or a conical shape.

[0098] Referring to FIG. 13, in an electronic device (101) according to one embodiment, at least a portion of the first recessed area (715) may have any one of a hyperbolic shape, an exponential shape, and a conical shape. For example, at least a portion of the first front member (610) may be formed to have an incline such that at least a portion of the first recessed area (715) faces the first side (413), and the incline may be formed in any one of a hyperbolic shape, an exponential shape, and a conical shape. For example, the incline of the first recessed area (715) may be formed in a shape such that a portion of the plurality of emission holes (713) constitutes an inlet of the horn speaker, and a portion of the first side (413) of the first housing (410) constitutes an outlet of the horn speaker.

[0099] FIG. 14 is an enlarged view of a cross-section taken in the C-C' direction of FIG. 8 in a folded state of a foldable housing (400) according to one embodiment.

[0100] For example, referring to FIG. 14, an electronic device (101) according to one embodiment may be configured such that the first housing (410) and the second housing (420) face each other in a folded state of the foldable housing (400), as in the case of FIG. 2C or FIG. 4C. For example, an electronic device (101) according to one embodiment may be configured such that the first front member (610) and the second front member (620) face each other in a folded state of the foldable housing (400). For example, when the first front member (610) is in contact with both the second front member (620), sound emitted from the plurality of emission holes (713) may be blocked by the second front member (620) and may not be emitted to the outside, or a decrease in volume or sound shaking may occur. For example, when the foldable housing (400) is in a folded state, sound output from the speaker (700) within the foldable housing (400) can be emitted in the first direction through the sound path (705) and the emission hole and the emission port (716) formed by the first recess being spaced apart from the second front member (620).

[0101] FIG. 15 is a drawing showing a cross-section taken in the C-C' direction of FIG. 8 when the first front member (610) is positioned facing the bottom surface (735) in the unfolded state of the foldable housing (400) according to one embodiment.

[0102] For example, referring to FIG. 15, in an electronic device (101) according to one embodiment, when the flexible display (500) is placed so that the foldable housing (400) is in an unfolded state as in FIG. 2A or FIG. 4A and faces the bottom surface (735), the first front member (610) of the first housing (410) may come into contact with the bottom surface (735). For example, when the first front member (610) is in full contact with the bottom surface (735), sound emitted from the plurality of emission holes (713) may be blocked by the bottom surface (735) and may not be emitted to the outside, or a decrease in volume or sound shaking may occur. When the foldable housing (400) is in a folded state, sound output from the speaker (700) within the foldable housing (400) can be emitted in the first direction through the sound path (705) and the emission hole and the emission port (716) formed by the first recess being spaced apart from the bottom surface (735).

[0103] FIG. 16 is a cross-sectional view showing a cross-section taken in the C-C' direction of FIG. 8 in a folded state of a foldable housing (400) according to one embodiment.

[0104] For example, referring to FIG. 2C, FIG. 12 may be a cross-section taken in the A-A' direction for part a in the folded state of the electronic device (101) of FIG. 2C.

[0105] For example, referring to FIG. 4C, FIG. 12 may be a cross-section taken in the B-B' direction with respect to part b in the folded state of the electronic device (101) of FIG. 4C.

[0106] Referring to FIGS. 2C, 4C, 12, and 16, in an electronic device (101) according to one embodiment, the second front member (620) may include a second sound emitting area (720) that includes a second recessed area (725) that is sunken toward the interior of the electronic device (101). The second sound emitting area (720) may be adjacent to the fourth side (423) and correspond to the first sound emitting area (710) in a folded state of the foldable housing (400). One side (3) of the second recessed area (725) may be connected to at least a portion of an edge of the fourth side (423) of the second front member (620) and configured to be spaced apart from the first recessed area (715) in a folded state of the foldable housing (400). At least a portion of the first recessed area (715) and the second recessed area (725) may each have an incline toward the fourth side surface (423).

[0107] For example, the first recessed area (715) may be formed by cutting a portion of the first front member (610), or the first front member (610) including the first recessed area (715) may be formed, for example, by injection molding. For example, one side (1) of the first recessed area (715) may be connected to the first side (413) of the first housing (410), and the other side (2) of the first recessed area (715) may include a plurality of discharge holes (713). For example, the first recessed area (715) may form a surface with one side (1) inclined toward the first side (413) of the first housing (410).

[0108] For example, the second recessed area (725) may be formed by cutting a portion of the second front member (620), or the second front member (620) including the second recessed area (725) may be formed, for example, by injection molding. For example, one side (3) of the second recessed area (725) may be connected to the fourth side (423) of the second housing (420), and the other side (4) of the second recessed area (725) may be adjacent to the plurality of discharge holes (713) when the foldable housing (400) is in an unfolded state. For example, the second recessed area (725) may form a surface with one side (3) inclined toward the fourth side (423) of the second housing (420).

[0109] For example, the first recessed area (715) and the second recessed area (725) can amplify the sound emitted to the outside through the portion having the slope, respectively. For example, the first recessed area (715) and the second recessed area (725) can each have at least a portion cut to form an inclined surface in the first direction (e.g., in the opposite direction of the plurality of emission holes (713)). For example, in the folded state of the foldable housing (400), one side of the inclined surface formed in the second recessed area (725) can be adjacent to the contact surface of the first front member (610) and the second front member (620), and the other side of the inclined surface formed in the second recessed area (725) can be connected to at least a portion of the fourth side surface (423) of the second housing (420). For example, the depth of one side (3) near the fourth side (423) of the second recessed area (725) may be formed to be greater than the depth of the other side (4) adjacent to the plurality of emission holes (713) of the second recessed area (725). For example, one side (3) and / or the other side (4) of the second recessed area (725) may be formed to have a depth of approximately 0.1 mm to 0.3 mm.

[0110] For example, in the folded state of the foldable housing (400), the first recessed area (715) and the second recessed area (725) can amplify sound emitted to the outside. For example, in the folded state of the foldable housing (400), sound output from the speaker (700) can pass through the sound path (705) and the plurality of emission holes (713) formed inside the foldable housing (400) and then pass between the inclined surface of the first recessed area (715) and the inclined surface of the second recessed area (725) to be emitted to the outside. For example, the distance between the first recessed area (715) and the second recessed area (725) can be formed so that the portion adjacent to the plurality of emission holes (713) is narrow and the portion adjacent to the outside of the electronic device (101) is wide.

[0111] Referring to FIG. 16, in the electronic device (101) according to one embodiment, the inclined surface formed in the second recessed area (725) may be formed asymmetrically with respect to the inclined surface formed in the first recessed area (715) based on the contact surface of the first front member (610) and the second front member (620). In the electronic device (101) according to one embodiment, at least a portion of the first recessed area (715) may have one of a hyperbolic shape, an exponential shape, and a conical shape, and at least a portion of the second recessed area (725) may have another of a hyperbolic shape, an exponential shape, and a conical shape.

[0112] For example, at least a portion of the second front member (620) is formed to have an incline such that at least a portion of the first recessed area (715) faces the first side (413), and the inclined surface having the incline can be cut into any one of a hyperbolic shape, an exponential shape, and a conical shape. For example, at least a portion of the second front member (620) is formed to have an incline such that at least a portion of the second recessed area (725) faces the fourth side (423), and the inclined surface having the incline can be formed into a shape different from the first recessed area (715) from the hyperbolic shape, the exponential shape, and the conical shape. For example, the slope of the first recess area (715) and the slope of the second recess area (725) can be formed in a shape in which a portion of the plurality of emission holes (713) constitutes an inlet of the horn speaker and a portion of the first side (413) of the first housing (410) constitutes an outlet of the horn speaker.

[0113] FIG. 17 is a cross-sectional view showing a cross-section taken in the C-C' direction of FIG. 8 in a folded state of a foldable housing (400) according to one embodiment.

[0114] For example, referring to FIG. 2C, FIG. 12 may be a cross-section taken in the A-A' direction for part a in the folded state of the electronic device (101) of FIG. 2C.

[0115] For example, referring to FIG. 4C, FIG. 12 may be a cross-section taken in the B-B' direction with respect to part b in the folded state of the electronic device (101) of FIG. 4C.

[0116] Referring to FIGS. 2C, 4C, and 17, the second front member (620) of the electronic device (101) according to one embodiment can be in partial contact with the first front member (610) in correspondence with the first front member (610) in the folded state of the foldable housing (400).

[0117] In an electronic device (101) according to one embodiment, the second front member (620) may include a second sound emitting area (720) including a second recessed area (725) that is sunken toward the inside of the electronic device (101). The second sound emitting area (720) may be adjacent to a fourth side (423) of the second housing (420) and may correspond to the first sound emitting area (710) in a folded state of the foldable housing (400). One side (3) of the second recessed area (725) may be adjacent to a plurality of emission holes (713) of the first front member (610), and the other side (4) of the second recessed area (725) may be connected to the fourth side (423) of the second housing (420). For example, the second recessed area (725) may be configured to be spaced apart from the first front member (610) in a folded state of the foldable housing (400).

[0118] In one embodiment, the electronic device (101) has an emission port (716) that is open in a first direction by a separation space formed by the second recessed area (725) of the second sound emission area (720) being spaced apart from the first front member (610) in the folded state of the foldable housing (400), and sound output from the speaker (700) can be emitted to the outside of the electronic device (101) through the emission port (716). For example, in the folded state of the foldable housing (400), the first front member (610) and the second front member (620) can prevent sound output from the speaker (700) from being emitted to a portion where the first front member (610) and the second front member (620) come into contact. For example, in the folded state of the foldable housing (400), the sound output from the speaker (700) can be sequentially emitted to the outside through the sound path (705), the plurality of emission holes (713), and the inclined surface of the second recessed area (725). For example, in the folded state of the foldable housing (400), the second recessed area (725) can be spaced apart from the first front member (610), and the plurality of emission holes (713) can be formed in a shape that has an incline toward the spaced apart space. For example, in the folded state of the foldable housing (400), since the second recessed area (725) is spaced apart from the first front member (610), the sound output from the speaker (700) can be emitted in the first direction rather than the front of the first housing (410) through the plurality of emission holes (713). For example, when the foldable housing (400) is in a folded state, if the sound output from the speaker (700) is emitted toward the front of the first housing (410), the sound may be blocked by the second front member (620), resulting in sound reduction and sound vibration in a specific frequency band. For example, the second recessed area (725) may serve as a passage connecting the plurality of emission holes (713) and the outside when the foldable housing (400) is in a folded state.

[0119] In an electronic device (101) according to one embodiment, at least a portion of the second recessed area (725) may be inclined toward the fourth side surface (423). For example, the second recessed area (725) may be formed by cutting a portion of the second front member (620). Alternatively, the second front member (620) including the second recessed area (725) may be formed, for example, by injection molding. For example, one side (3) of the second recessed area (725) may be connected to the fourth side surface (423) of the second housing (420), and the other side (4) of the second recessed area (725) may be adjacent to the plurality of emission holes (713) in the unfolded state of the foldable housing (400). For example, the second recessed area (725) may form an inclined surface with one side (3) facing the fourth side (423) of the second housing (420). For example, the second recessed area (725) may amplify sound emitted to the outside through a portion having an incline. For example, the second recessed area (725) may be formed with an inclined surface in the first direction (e.g., in the opposite direction of the plurality of emission holes (713)) by at least a portion being cut off. For example, in the foldable housing (400) in a folded state, one side of the inclined surface formed in the second recessed area (725) may be adjacent to a contact surface where the first front member (610) and the second front member (620) come into contact, and the other side of the inclined surface formed in the second recessed area (725) may be connected to at least a portion of the fourth side (423) of the second housing (420). For example, the depth of one side (3) near the fourth side (423) of the second recessed area (725) may be formed to be greater than the depth of the other side adjacent to the plurality of emission holes (713) of the second recessed area (725). For example, sound emitted to the outside by the second recessed area (725) may be amplified.For example, in the folded state of the foldable housing (400), sound output from the speaker (700) can be sequentially emitted to the outside through the sound path (705), the plurality of emission holes (713) and the second recess area (725) formed inside the foldable housing (400).

[0120] Referring to FIG. 13, in an electronic device (101) according to one embodiment, at least a portion of the second recessed area (725) may have any one of a hyperbolic shape, an exponential shape, and a conical shape. For example, at least a portion of the second front member (620) may be formed to have an incline such that at least a portion of the second recessed area (725) faces the fourth side surface (423), and the incline may be formed in any one of a hyperbolic shape, an exponential shape, and a conical shape. For example, the incline of the second recessed area (725) may be formed in a shape such that a portion of the plurality of emission holes (713) constitutes an inlet of the horn speaker, and a portion of the fourth side surface (423) of the second housing (420) constitutes an outlet of the horn speaker.

[0121] Fig. 18 is a diagram showing a frequency response curve for sound output from an electronic device (101) according to one embodiment. Fig. 19 is a diagram showing sound vibration for sound output from an electronic device (101) according to one embodiment.

[0122] For example, referring to FIG. 18, an electronic device (101) according to an embodiment can minimize a decrease in volume in a 3 to 5 kHz band by preventing a plurality of emission holes (713) from being blocked when (after) the first recess is formed in a portion of the first front member (610). In an electronic device (101) according to an embodiment, when (after) the first recess is formed in a portion of the first front member (610), a sound enhancement effect evenly distributed across the entire frequency band and a sound enhancement effect of about 20 dB or more in the mid- and high-frequency portion (3 to 5 kHz) can be exhibited compared to a case where (before) the electronic device does not have the first recess. For example, a 20 dB sound pressure deviation in a 3 to 5 kHz band can lower sound clarity, causing the sound to sound muffled. For example, a 10 dB sound pressure deviation in a 500 Hz to 1 kHz band can reduce the richness of low-frequency sounds.

[0123] For example, referring to FIG. 19, an electronic device (101) according to one embodiment can prevent sound shaking due to blockage of a plurality of emission holes (713) by having a first recess formed in a portion of a first front member (610) when the flexible display (500) faces the bottom surface (735) in a folded or unfolded state of the foldable housing (400). For example, referring to a circled portion of FIG. 19, the occurrence of sound shaking can be quantitatively analyzed by comparing signal intensities in an acoustic frequency band. For example, in an electronic device (101) according to one embodiment, when the flexible display (500) faces the bottom surface (735) in the folded or unfolded state of the foldable housing (400), the vibration can be reduced (the frequency components are slightly changed) in both 160 Hz to 1.6 Hz multi-tone and music tone by the first recess spaced apart from the second front member (620).

[0124] Referring to FIGS. 2A to 3, in an electronic device (101) according to one embodiment, a first side (413) of a first housing (410) and a fourth side (423) of a second housing (420) may each be substantially parallel to a longitudinal direction of a hinge assembly. For example, the first side (413) and the fourth side (423) may each be substantially parallel to a folding axis (F). For example, the first side (413) and the fourth side (423) may be substantially parallel. For example, in the first housing (410), both sides of the first side (413) may be a second side (416) and a third side (419), and the second side (416) and the third side (419) may be substantially parallel. For example, in the second housing (420), the opposite sides of the fourth side (423) may be the fifth side (426) and the sixth side (429), and the fifth side (426) and the sixth side (429) may be substantially parallel. For example, in the folded state of the foldable housing (400), the first side (413) and the fourth side (423) may be adjacent to each other, the second side (416) and the fifth side (426) may be adjacent, and the third side (419) and the sixth side (429) may be adjacent.

[0125] Referring to FIGS. 4A to 5, in an electronic device (101) according to one embodiment, a first side (413) of a first housing (410) and a fourth side (423) of a second housing (420) may each be substantially perpendicular to a longitudinal direction of a hinge assembly. For example, the first side (413) and the fourth side (423) may each be substantially perpendicular to a folding axis (F). For example, the first side (413) and the fourth side (423) may face substantially the same direction (+Y). For example, in the first housing (410), the first side (413) may be substantially parallel to the third side (419), and the second side (416) may be substantially perpendicular to the first side (413) and the third side (419). For example, in the second housing (420), the fourth side (423) may be substantially parallel to the sixth side (429), and the fifth side (426) may be substantially perpendicular to the fourth side (423) and the sixth side (429). For example, in the folded state of the foldable housing (400), the first side (413) and the fourth side (423) may be adjacent to each other, the second side (416) and the fifth side (426) may be adjacent, and the third side (419) and the sixth side (429) may be adjacent.

[0126] Referring to FIGS. 1 to 5, an electronic device (101) according to one embodiment may include a foldable housing (e.g., a housing structure), a hinge assembly (e.g., a hinge device (240, 240-1) of FIG. 3 or a hinge device (340, 340-1) of FIG. 5), a flexible display (500) (e.g., a first display (230) of FIG. 2A or a first display (330) of FIG. 4A), and a speaker (700).

[0127] A foldable housing (400) of an electronic device (101) according to one embodiment may include a first housing (410) including a first side (413), a second side (416), and a third side (419), and a fourth side (423), a fifth side (426), and a sixth side (429).

[0128] A hinge assembly of an electronic device (101) according to one embodiment can foldably connect a first housing (410) and a second housing (420).

[0129] A flexible display (500) of an electronic device (101) according to one embodiment may include a first display portion (503) accommodated within a first housing (410) and a second display portion (506) accommodated within a second housing (420).

[0130] A speaker (700) of an electronic device (101) according to one embodiment is positioned adjacent to a first side (413) below a first display portion (503) and can emit sound through an acoustic path (705) formed inside a first housing (410).

[0131] In an electronic device (101) according to one embodiment, in a folded state of the foldable housing (400), the first side (413) and the fourth side (423) may correspond to each other, the second side (416) and the fifth side (426) may correspond to each other, and the third side (419) and the sixth side (429) may correspond to each other.

[0132] A foldable housing (400) of an electronic device (101) according to one embodiment may include a first elastic member (e.g., a first front member (610)) extending from a first side (413), a second side (416), and a third side (419) of a first housing (410) along an edge of a side of a first display portion (503), and a second elastic member (e.g., a second front member (620)) extending from a fourth side (423), a fifth side (426), and a sixth side (429) of a second housing (420) along an edge of a side of a second display portion (506).

[0133] A first elastic member of an electronic device (101) according to one embodiment may include a first sound emission area (710) adjacent to a first side (413) and including a plurality of emission holes (713) connected to an acoustic path (705).

[0134] Referring to FIGS. 9 and 14, a first sound emission area (710) of an electronic device (101) according to one embodiment may include a first front area (e.g., a first recess area (715)) adjacent to a first side (413) and having a plurality of emission holes (713) formed therein, and a rear area (717) opposite the front area based on the plurality of emission holes (713).

[0135] In one embodiment, the electronic device (101) may have a first elastic member partially in contact with a second elastic member in a folded state of the foldable housing (400).

[0136] An electronic device (101) according to one embodiment may have a first front region (e.g., a first recessed region (715)) spaced apart from a second elastic member, and a rear region (717) in contact with the second elastic member.

[0137] Referring to FIGS. 10 and 11, in an electronic device (101) according to one embodiment, a support member (520) that supports at least one electronic component (e.g., a light sensor, a front camera (510)) may be placed within a first housing (410). For example, a speaker (700) may be placed adjacent to a first side (413) of the first housing (410) on one side of the front camera (510). For example, a first display portion (503) in the first housing (410) may be supported on the back by the support member (520).

[0138] In an electronic device (101) according to one embodiment, the sound path (705) may be formed by an internal space surrounded by the first side (413) of the first housing (410), the first display portion (503), or at least a portion of the support member (520). For example, one side of the internal space may be connected to the speaker (700) on the inside of the first elastic member and the first display portion (503), and the other side of the internal space may be connected to a plurality of emission holes (713). For example, the support member (520) may have a space connected from the speaker (700) to the plurality of emission holes (713). For example, the space provided in the support member (520) may be surrounded by the first side (413) of the first housing (410) and the first display portion (503), thereby forming the sound path (705). For example, the sound path (705) may allow sound output from the speaker (700) to be reflected or guided by the support member (520), the first side (413), or the first display portion (503) and emitted to the plurality of emission holes (713). For example, an internal space surrounded by the support member (520), the first side (413), or the first display portion (503) may be formed at a position corresponding to the speaker (700) and the plurality of emission holes (713).

[0139] In one embodiment, the electronic device (101) may have an emission port (716) formed in a first direction by a separation space formed by the front region of the first sound emission region (710) being separated from the second elastic member when the foldable housing (400) is in a folded state. In one embodiment, the electronic device (101) may allow sound output from the speaker (700) to be emitted to the outside of the electronic device (101) through the emission port (716). In one embodiment, the electronic device (101) may prevent sound output from the speaker (700) from being emitted in a second direction opposite to the first direction when the foldable housing (400) is in a folded state by having the rear region (717) come into contact with the second elastic member. For example, the first direction may be a direction toward the outside of the electronic device (101). For example, the second direction may be a direction toward the inside of the electronic device (101). For example, in the folded state of the foldable housing (400), the sound output from the speaker (700) may pass through the sound path (705) and the plurality of emission holes (713) and then pass between the front region and the second elastic member to be emitted to the outside. For example, in the folded state of the foldable housing (400), the sound output from the speaker (700) may pass through the sound path (705) and the plurality of emission holes (713) and then be blocked from being emitted in the second direction by the contact surface where the rear region (717) and the second elastic member come into contact. For example, in the folded state of the foldable housing (400), the sound output from the speaker (700) may pass through the sound path (705) and the plurality of emission holes (713) and then be reflected by the contact surface where the rear region (717) and the second elastic member come into contact and then be emitted in the first direction.

[0140] Referring to FIG. 9, in an electronic device (101) according to one embodiment, the first elastic member may further include a first lateral region (718) and a second lateral region (719) located on both sides of a first front region (e.g., a first recessed region (715)) and a rear region (717) in a first sound emitting region (710). In an electronic device (101) according to one embodiment, when the foldable housing (400) is in a folded state, the first lateral region (718) and the second lateral region (719) may come into contact with the second elastic member to prevent sound output from the speaker (700) from being emitted to both sides of the front region and the rear region (717). For example, in the folded state of the foldable housing (400), sound output from the speaker (700) may be blocked from being emitted in a third or fourth direction perpendicular to the first and second directions by the contact surfaces where the first lateral region (718) and the second lateral region (719) come into contact with the second elastic member after passing through the sound path (705) and the plurality of emission holes (713). For example, in the folded state of the foldable housing (400), sound output from the speaker (700) may be reflected by the contact surfaces where the first lateral region (718) and the second lateral region (719) come into contact with the second elastic member after passing through the sound path (705) and the plurality of emission holes (713) and may be emitted in the first direction.

[0141] Referring to FIGS. 2C, 4C, 12, and 16, in an electronic device (101) according to one embodiment, the second elastic member may include a second sound emitting area (720) including a second front area (e.g., a second recess area (725)) that is recessed toward the inside of the electronic device (101). The second sound emitting area (720) may be adjacent to the fourth side (423) and correspond to the first sound emitting area (710) in a folded state of the foldable housing (400). One side (3) of the second front area (e.g., the second recess area (725)) may be connected to at least a portion of an edge of the fourth side (423) of the second elastic member and configured to be spaced apart from the first front area (e.g., the first recess area (715)) in a folded state of the foldable housing (400). The first front region (e.g., the first recess region (715)) and the second front region (e.g., the second recess region (725)) may each have an incline such that at least a portion thereof faces the fourth side surface (423).

[0142] For example, the first front region (e.g., the first recessed region (715)) and the second front region (e.g., the second recessed region (725)) can each amplify sound emitted to the outside through a portion having an incline. For example, the first front region (e.g., the first recessed region (715)) and the second front region (e.g., the second recessed region (725)) can each have at least a portion cut to form an incline in the first direction (e.g., in the opposite direction of the plurality of emission holes (713). For example, in the folded state of the foldable housing (400), one side of the incline formed in the second front region (e.g., the second recessed region (725)) can be adjacent to a contact surface between the first elastic member and the second elastic member, and the other side of the incline formed in the second front region (e.g., the second recessed region (725)) can be connected to at least a portion of the fourth side surface (423) of the second housing (420). For example, the depth of one side (3) close to the fourth side (423) of the second front area (e.g., the second recess area (725)) may be formed to be greater than the depth of the other side (4) adjacent to the plurality of emission holes (713) of the second front area (e.g., the second recess area (725)). For example, sound emitted to the outside by the first recess area (715) and the second recess area (725) may be amplified. For example, in the folded state of the foldable housing (400), sound output from the speaker (700) may pass through the sound path (705) and the plurality of emission holes (713) formed inside the foldable housing (400) and then pass between the inclined surface of the first front area (e.g., the first recess area (715)) and the inclined surface of the second front area (e.g., the second recess area (725)) to be emitted to the outside. For example, the distance between the first front region (e.g., the first recess region (715)) and the second front region (e.g., the second recess region (725)) may be formed so that the portion adjacent to the plurality of emission holes (713) is narrow and the portion adjacent to the outside of the electronic device (101) is wide.

[0143] Referring to FIG. 16, in the electronic device (101) according to one embodiment, the inclined surface formed in the second front region (e.g., the second recessed region (725)) may be formed asymmetrically with respect to the inclined surface formed in the first front region (e.g., the first recessed region (715)) based on the contact surface of the first elastic member and the second elastic member. In the electronic device (101) according to one embodiment, the first front region (e.g., the first recessed region (715)) may have at least a portion of a shape of any one of a hyperbolic shape, an exponential shape, and a conical shape, and the second front region (e.g., the second recessed region (725)) may have at least a portion of another shape of the hyperbolic shape, an exponential shape, and a conical shape.

[0144] For example, at least a portion of the second elastic member is formed to have an incline such that at least a portion of the first front region (e.g., the first recessed region (715)) is inclined toward the first side surface (413), wherein the inclined surface can be formed in any one of a hyperbolic shape, an exponential shape, and a conical shape. For example, at least a portion of the second elastic member is formed to have an incline such that at least a portion of the second front region (e.g., the second recessed region (725)) is inclined toward the fourth side surface (423), wherein the inclined surface can be formed in any one of a hyperbolic shape, an exponential shape, and a conical shape different from the first front region (e.g., the first recessed region (715)). For example, the inclined surface of the first front region (e.g., the first recessed region (715)) and the inclined surface of the second front region (e.g., the second recessed region (725)) can be formed in a shape such that a portion of the plurality of emission holes (713) constitutes an inlet of the horn speaker and a portion of the first side (413) of the first housing (410) constitutes an outlet of the horn speaker.

[0145] Referring to FIGS. 2C, 4C, and 17, the second elastic member of the electronic device (101) according to one embodiment can be in partial contact with the first elastic member in correspondence with the first elastic member in the folded state of the foldable housing (400).

[0146] In an electronic device (101) according to one embodiment, the second elastic member may include a second sound emitting area (720) including a second front area (e.g., a second recess area (725)) that is sunken toward the inside of the electronic device (101). The second sound emitting area (720) may be adjacent to a fourth side (423) of the second housing (420) and may correspond to the first sound emitting area (710) in a folded state of the foldable housing (400). One side (3) of the second front area (e.g., the second recess area (725)) may be adjacent to a plurality of emission holes (713) of the first elastic member, and the other side (4) of the second front area (e.g., the second recess area (725)) may be connected to the fourth side (423) of the second housing (420). For example, it may be configured to be spaced apart from the first elastic member in the folded state of the foldable housing (400).

[0147] In one embodiment, the electronic device (101) has an emission port (716) that is open in a first direction by a separation space formed by a second front region (e.g., a second recessed region (725)) of a second sound emission region (720) being spaced apart from a first elastic member when the foldable housing (400) is in a folded state, and sound output from the speaker (700) can be emitted to the outside of the electronic device (101) through the emission port (716). For example, in the folded state of the foldable housing (400), the first elastic member and the second elastic member can prevent sound output from the speaker (700) from being emitted to a portion where the first elastic member and the second elastic member are in contact. For example, in the folded state of the foldable housing (400), the sound output from the speaker (700) can be sequentially emitted to the outside through the sound path (705), the plurality of emission holes (713), and the inclined surface of the second front region (e.g., the second recessed region (725)). For example, in the folded state of the foldable housing (400), the second front region (e.g., the second recessed region (725)) can be spaced apart from the first elastic member, and the plurality of emission holes (713) can be formed in a shape having an incline toward the spaced apart space. For example, in the folded state of the foldable housing (400), since the second front region (e.g., the second recessed region (725)) is spaced apart from the first elastic member, the sound output from the speaker (700) can be emitted in the first direction rather than the front of the first housing (410) through the plurality of emission holes (713). For example, when the foldable housing (400) is in a folded state, if the sound output from the speaker (700) is emitted toward the front of the first housing (410), the sound may be blocked by the second elastic member, resulting in sound reduction and sound vibration in a specific frequency band. For example, the second front region (e.g., the second recessed region (725)) may serve as a passage connecting the plurality of emission holes (713) and the outside in the folded state of the foldable housing (400).

[0148] At least a portion of the second front region (e.g., the second recessed region (725)) may have an incline toward the fourth side surface (423). For example, the second front region (e.g., the second recessed region (725)) may amplify sound emitted to the outside through the portion having the incline. For example, the second front region (e.g., the second recessed region (725)) may have an incline formed in the first direction (e.g., in the opposite direction of the plurality of emission holes (713)) by cutting molding or injection molding. For example, in a folded state of the foldable housing (400), one side of the incline formed in the second front region (e.g., the second recessed region (725)) may be adjacent to a contact surface where the first elastic member and the second elastic member come into contact, and the other side of the second front region (e.g., the second recessed region (725)) may be connected to at least a portion of the fourth side surface (423) of the second housing (420).
