Description

foldable electronic devices

[0001] Various embodiments of the present disclosure relate to a foldable electronic device that provides stereo sound as a foldable electronic device.

[0002] With the advancement of electronic, information, and communication technologies, various functions are being integrated into a single portable communication or electronic device. For example, smartphones include communication functions as well as audio playback, camera, or electronic notebook capabilities, and even more diverse functions can be implemented through the additional installation of applications.

[0003] With the widespread use of personal or portable communication devices such as smartphones, user demand for portability and ease of use is increasing. For example, touchscreen displays serve as output devices that display visual information, and can also provide a virtual keypad that replaces mechanical input devices (e.g., button inputs). Consequently, portable communication devices or electronic devices can be miniaturized while providing the same or even enhanced usability (e.g., larger screens). On the other hand, with the commercialization of flexible displays—such as foldable or rollable ones—the portability and ease of use of electronic devices are expected to improve even further.

[0004] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0005] A multi-foldable electronic device according to one embodiment may include a foldable housing comprising a first housing, a second housing, and a third housing; a first hinge structure disposed to rotatably connect the first housing and the second housing; a second hinge structure disposed to rotatably connect the second housing and the third housing; a first acoustic tube section comprising a first acoustic tube formed to be open toward the front of the first housing, a first speaker disposed on a first side of the upper side of the first housing; and a second acoustic tube section comprising a second acoustic tube formed to penetrate the front and rear of the second housing. When the first housing and the second housing are in a folded state, the first acoustic tube and the second acoustic tube may be connected.

The communication module (190) may operate independently from the processor (120) (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 (190) may include a wireless communication module (192) (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 (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (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 LAN or WAN)). These various types of communication modules can 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 (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0062] The wireless communication module (192) 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 (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in the high-frequency band, such as beamforming, massive MIMO (multiple-input and multiple-output), full-dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large-scale antenna.

Even when the electronic device (101) is folded, the first speaker (311) and the second speaker (312) output sound to the left and right sides of the user, respectively, thereby providing stereo sound to the user. Due to the structure of the first speaker (311) and the second speaker (312), stereo sound can be provided even when the user uses the sub-display (225) in the folded state of the electronic device (101).

[0176] According to one embodiment, the electronic device (101) can provide a call reception sound so that the user can make a call even in the folded state. The electronic device (101) according to one embodiment can provide a call reception sound to the user even in the folded state without adding any other speakers other than the first speaker (311) and the second speaker (312). The electronic device (101) according to one embodiment can provide a call reception sound so that the user can make a call in both the folded and unfolded states as well as in stereo sound with only two speakers (310).

[0177] An electronic device (101) according to one embodiment is positioned to provide stereo sound regardless of whether it is in an unfolded or folded state, as illustrated, so as to provide the user with a three-dimensional and vivid listening experience.

[0178] The electronic device (101) can form a housing structure that provides a call reception sound so that the user can make a call while in a folded state using the first speaker (311). The specific structure will be described later.

[0179] Figure 8 is an enlarged perspective view of area C of Figure 7b.

[0180] The embodiment of FIG. 8 can be optionally combined with the embodiments of FIGS. 1 to 7b and FIGS. 9 to 23.

[0181] Among the configurations illustrated in Fig. 8, the same reference numbers are used for configurations that are substantially the same or similar to the configuration described above.

[0182] The structure illustrated in FIG. 8 is an example for convenience of explanation, and the scope of the present disclosure is not limited by the illustrated shape and structure.

[0183] FIG. 8 is an enlarged perspective view of the upper part of an electronic device (e.g., the electronic device (101) of FIG. 1 or the electronic device (101) of FIGS. 2a, 2b, 3a, 3b, 3c, and 3d) in a folded state.

[0184] Referring to FIG. 8, the electronic device (101) can be arranged in the order of the second housing (220), the first housing (210), and the third housing (230) with the sub-display (225) as the starting point in a folded state.

[0185] According to one embodiment, the second housing (220) may include a receiver hole (2283a). The receiver hole (2283a) may be located in a groove (2251) formed at the upper edge of the sub-display (225). The receiver hole (2283a) may be formed to output sound transmitted through a second sound tube (e.g., the second sound tube (228) of FIG. 16b) to be described later. In FIG. 8, the size of the receiver hole (2283a) may be somewhat exaggerated for convenience of explanation.

[0186] According to one embodiment, the sound coming from the receiver hole (2283a) may be sound output from a first speaker (e.g., the first speaker (311) of FIG. 7a) disposed within the first housing (210). The sound output from the first speaker (311) may pass through the second acoustic tube (228), which will be described later, and diffuse from the receiver hole (2283a). The sound emitted from the receiver hole (2283a) may correspond to D3 of FIG. 7b.

[0187] According to one embodiment, an acoustic conduit (e.g., a third acoustic conduit (2182)) may be formed on one side of the first housing (210) (e.g., a first-third side (213)). The third acoustic conduit (2182) may be formed to penetrate one side of the first housing (210) (e.g., a first-third side (213)). The third acoustic conduit (2182) may be a passage through which sound output from the first speaker (311) passes. When sound is output from the first speaker (311), a portion of the output sound may be diffused to the outside through the third acoustic conduit (2182). The sound emitted from the third acoustic conduit (2182) may correspond to D2 in FIG. 7b.

[0188] An electronic device (101) according to one embodiment may have a structure that outputs sound in various directions using a first speaker (311). The sound output from the first speaker (311) may be diffused laterally through the third acoustic duct (2182) of the first housing (210) when the electronic device (101) is in a folded state. The sound output from the first speaker (311) may be diffused in a direction toward the rear of the second housing (220) (e.g., the side where the sub-display (225) is placed) through the receiver hole (2283a) when the electronic device (101) is in a folded state. When a user makes a call using the electronic device (101) in a folded state, the call volume may be received through the receiver hole (2283a).

[0189] An electronic device (101) according to one embodiment implements a housing structure that can be used for various purposes, such as sound output and transmission of call reception sound, using a single speaker (e.g., a first speaker (311)), thereby minimizing the number of speakers placed within the multi-foldable electronic device (101). By minimizing the number of speakers, mounting space within the housing can be secured.

[0190] FIG. 9a is a cross-sectional view of a third housing of an electronic device according to one embodiment of the present disclosure, cut along the line EE of FIG. 8.

[0191] Fig. 9b is a perspective view of Fig. 9a viewed diagonally.

[0192] FIG. 10 is an exploded perspective view of components disposed on the upper front of a third housing of an electronic device according to one embodiment of the present disclosure.

[0193] The embodiments of FIGS. 9A, 9B and 10 can be optionally combined with the embodiments of FIGS. 1 to 8 and FIGS. 11 to 23.

[0194] Among the configurations illustrated in FIGS. 9a, 9b and 10, the same reference numbers are used for configurations that are substantially the same or similar to the configuration described above.

[0195] The structures illustrated in FIGS. 9a, 9b, and 10 are exemplary for convenience of explanation, and the scope of the present disclosure is not limited by the illustrated shapes and structures.

[0196] Referring to FIGS. 9a, 9b, and 10, an electronic device (e.g., the electronic device (101) of FIG. 1 or the electronic device (101) of FIG. 2a, 2b, 3a, 3b, 3c, and 3d) may include a first housing (210).

[0197] According to one embodiment, the first housing (210) may include a first speaker (311) and a first acoustic tube (218) (e.g., a first acoustic duct). The first acoustic tube (218) may form a passage that diffuses sound output from the first speaker (311) to the outside of the first housing (210).

[0198] According to one embodiment, the first acoustic tube (218) may be formed on the upper side of the first speaker (311). The first acoustic tube (218) may be formed between the first speaker (311) and the first-third side (213), which is the upper side of the first housing (210).

[0199] According to one embodiment, the first sound pipe (218) may include an input pipe (2181), a third sound pipe (2182), and a first sound pipe (2183). The input pipe (2181) may be a pipe through which sound output from the first speaker (311) initially enters. The sound output from the first speaker (311) may be transmitted to another part through the input pipe (2181).

[0200] According to one embodiment, the third acoustic conduit (2182) and the first acoustic conduit (2183) may be formed by branching from the input conduit (2181). The third acoustic conduit (2182) may be connected to the input conduit (2181). The first acoustic conduit (2183) may be connected to the input conduit (2181).

[0201] According to one embodiment, the third acoustic conduit (2182) may be extended toward one side of the first housing (210) (e.g., the first-third side (213)). The third acoustic conduit (2182) may be formed so that sound transmitted from the input conduit (2181) diffuses through one side of the first housing (210) (e.g., the first-third side (213)).

[0202] According to one embodiment, the first acoustic conduit (2183) may be extended toward the front of the first housing (210). The first acoustic conduit (2183) may be extended toward the first protective member (216). The first acoustic conduit (2183) may be formed to diffuse sound transmitted from the input conduit (2181) through the front of the first housing (210).

[0203] According to one embodiment, sound output from the first speaker (311) can be diffused to the outside of the first housing (210) through the input conduit (2181), the third sound conduit (2182), and the first sound conduit (2183). Sound output from the first speaker (311) can be diffused from the upper part (or upper edge portion) of the first housing (210) through the first sound conduit section (218).

[0204] According to some embodiments, the third acoustic conduit (2182) may be omitted. Omitting the third acoustic conduit (2182) may mean that no sound-diffusing hole is formed on the first-third side (213) of the first housing (210). For example, the third acoustic conduit (2182) may be omitted so that sound passing through the input conduit (2181) is configured to diffuse only through the first acoustic conduit (2183). If the third acoustic conduit (2182) is omitted, the sound output from the first speaker (311) may not diffuse toward the side of the first housing (210) (e.g., the first-third side (213)) but may diffuse only through the front of the first housing (210).

[0205] According to one embodiment, the electronic device (101) may include a first protective member (216). The first protective member (216) may be disposed on the outer edge of the flexible display (203).

[0206] According to one embodiment, a through hole (2161) may be formed in the first protective member (216). The through hole (2161) may be formed at a position corresponding to the first sound conduit (2183). Sound diffused through the first sound conduit (2183) may pass through the through hole (2161).

[0207] According to one embodiment, the end of the first acoustic conduit (2183) may be positioned to overlap with the through hole (2161) of the first protective member (216).

[0208] According to one embodiment, the electronic device (101) may further include an elastic member (320). The elastic member (320) may be disposed in a through hole (2161) of the first protective member (216). The elastic member (320) may be disposed to surround the edge of the through hole (2161) of the first protective member (216). The elastic member (320) may have a hollow portion having a shape corresponding to the shape of the through hole (2161) of the first protective member (216).

[0209] According to one embodiment, the elastic member (320) may include an elastic material such as rubber, latex, silicone, or polyurethane. The material of the elastic member (320) is not limited thereto.

[0210] According to one embodiment, as illustrated in FIG. 10, the elastic member (320) may include a peripheral portion (323), a first rib (321) extending from the upper end of the peripheral portion (323), and a second rib (322) extending from the lower end of the peripheral portion (323).

[0211] According to one embodiment, the first rib (321) may be formed to protrude outwardly from the upper end of the peripheral portion (323). The first rib (321) may extend outwardly along the upper end of the peripheral portion (323).

[0212] According to one embodiment, the second rib (322) may be formed to protrude outward from the bottom of the perimeter (323). The second rib (322) may extend outward along the bottom of the perimeter (323).

[0213] According to one embodiment, the first rib (321) and the second rib (322) may be formed parallel to each other.

[0214] According to one embodiment, the elastic member (320) may be coupled to the first protective member (216). The elastic member (320) may be fitted into the through hole (2161) of the first protective member (216). The elastic member (320) may be coupled to the first protective member (216) by fitting a recess defined on the outer side of the elastic member (320) by the first rib (321), the periphery (323), and the second rib (322) of the elastic member (320) into the through hole (2161) of the first protective member (216). According to some embodiments, the periphery (323) of the elastic member (320) and the edge of the through hole (2161) of the first protective member (216) may be bonded by an adhesive member.

[0215] According to one embodiment, the elastic member (320) may be positioned so that a portion of it protrudes above the first protective member (216). The first rib (321) of the elastic member (320) may be positioned above the first protective member (216).

[0216] According to one embodiment, a first protective member (216) to which an elastic member (320) is attached may be disposed on the front surface of a first housing (210). The first protective member (216) may be coupled to the first housing (210). The first protective member (216) may be fixedly coupled to the first housing (210) in various ways, such as a snap-fit ​​method, an assembly method, or an adhesive method.

[0217] According to one embodiment, the electronic device (101) may further include an adhesive member (330). The adhesive member (330) may be positioned between the elastic member (320) and the first housing (210). The adhesive member (330) may be bonded to the second rib (322) of the elastic member (320). The adhesive member (330) may be bonded to the front surface of the first housing (210). The adhesive member (330) may be positioned to wrap around the top perimeter of the first acoustic tube (2183). The adhesive member (330) may be positioned so as to bond the bottom of the elastic member (320) and the front surface of the first housing (210).

[0218] According to one embodiment, the adhesive member (330) can fix the elastic member (320) by adhering it to the first housing (210). The adhesive member (330) may have the function of fixing the shape of the elastic member (320) so as to prevent the elastic member (320) from being deformed by an external force. The adhesive member (330) may fix the elastic member (320) to the first housing (210) so that the elastic member (320) is not detached from the first protective member (216) due to the deformation of the elastic member (320). The adhesive member (330) may be positioned to prevent sound leakage in the space between the elastic member (320) and the first housing (210). The adhesive member (330) may be made of an elastic material.

[0219] FIG. 11 is a perspective view showing a first housing and a portion of a second housing side of an electronic device in an unfolded state according to one embodiment of the present disclosure.

[0220] FIG. 12 is a cross-sectional view of a first housing and a second housing of an electronic device according to one embodiment of the present disclosure, cut along the line EE of FIG. 8.

[0221] FIG. 13 is a cross-sectional view of a second housing of an electronic device according to one embodiment of the present disclosure, cut along the line EE of FIG. 8.

[0222] The embodiments of FIGS. 11 to 13 can be optionally combined with the embodiments of FIGS. 1 to 10 and the embodiments of FIGS. 14 to 23.

[0223] For configurations shown in FIGS. 11 to 13 that are substantially identical or similar to the configuration described above, the same reference numerals are used.

[0224] The structures illustrated in FIGS. 11 to 13 are exemplary for convenience of explanation, and the scope of the present disclosure is not limited by the illustrated shapes and structures.

[0225] Referring to FIGS. 11 through 13, an electronic device (e.g., the electronic device (101) of FIG. 1 or the electronic device (101) of FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, FIG. 3c and FIG. 3d) may include a first housing (210), a second housing (220), a flexible display (203), and a sub-display (225).

[0226] FIG. 11 illustrates the arrangement relationship of the outlet (2283) of the sound-emitting holes (e.g., the second acoustic tube section (228)), the end of the third acoustic tube (2182), and the end of the first acoustic tube (2183) when the first housing (210) and the second housing (220) are unfolded. FIG. 12 illustrates the connection relationship between the first acoustic tube section (218) and the second acoustic tube section (228) when the electronic device (101) is folded so that the front of the first housing (210) and the front of the second housing (220) face each other. FIG. 13 illustrates the second acoustic tube section (228) and its surrounding configuration positioned on the upper part of the second housing (220).

[0227] According to one embodiment, the sub-display (225) may be placed on the opposite side of the second display area (A2) of the flexible display (203). The second display area (A2) of the flexible display (203) may be placed on the front side of the second housing (220). The sub-display (225) may be placed on the rear side of the second housing (220).

[0228] According to one embodiment, the second housing (220) may include a second acoustic tube section (228) (e.g., a second acoustic duct). The second acoustic tube section (228) may be located on the upper part of the second housing (220). The second acoustic tube section (228) may be positioned on the upper edge portion of the second housing (220). The second acoustic tube section (228) may be located on the upper side of the second display area (A2). The second acoustic tube section may be formed adjacent to the upper side of the second housing (220) (e.g., a second-third side (223)).

[0229] According to one embodiment, the second acoustic tube (228) may be formed to penetrate between the front and rear of the second housing (220). One end of the second acoustic tube (228) may be formed to be open toward the front of the second housing (220). The other end of the second acoustic tube (228) may be formed to be open toward the rear of the second housing (220).

[0230] According to one embodiment, when the electronic device (101) is folded, the second acoustic tube (228) may be positioned to overlap with the first acoustic tube (218). When the electronic device (101) is folded, the first acoustic tube (218) and the second acoustic tube (228) may be connected. When sound is output from the first speaker (311) while the electronic device (101) is folded, the sound may be transmitted to the second acoustic tube (228) connected to the first acoustic tube (218).

[0231] According to one embodiment, the second acoustic tube section (228) may include an inlet (2281), a second acoustic conduit (2282), and an outlet (2283). The second acoustic conduit (2282) may be a conduit connecting the inlet (2281) and the outlet (2283).

[0232] According to one embodiment, the inlet (2281) may be connected to the first acoustic tube (2183) when the electronic device (101) is in a folded state. The inlet (2281) may be a hole open toward the front of the second housing (220). The outlet (2283) may be a hole open toward the rear of the second housing (220).

[0233] According to one embodiment, when sound is output to the first speaker (311) while the electronic device (101) is in a folded state, the output sound may pass through the first sound conduit (2183) and enter the inlet (2281) of the second sound conduit (228). The sound entering through the inlet (2281) may pass through the second sound conduit (2282) and spread through the rear of the second housing (220) via the outlet (2283).

[0234] According to one embodiment, when the electronic device (101) is folded, the first acoustic tube section (218) and the second acoustic tube section (228) can form a single integrated acoustic tube section. When the electronic device (101) is folded, the first acoustic tube (2183) and the second acoustic tube (2282) can form a single connected acoustic tube.

[0235] According to one embodiment, an elastic member (320) may be disposed between the first acoustic tube section (218) and the second acoustic tube section (228). The elastic member (320) may be disposed so that sound passing through the space between the first acoustic tube section (218) and the second acoustic tube section (228) is not lost. The elastic member (320) may be disposed between the first acoustic tube section (218) and the second acoustic tube section (228) to reduce sound loss.

[0236] According to one embodiment, the elastic member (320) may be positioned to bring the first protective member (216) and the second protective member (226) into close contact. For example, the elastic member (320) may be positioned to seal the space between the first acoustic tube (2183) and the inlet (2281) of the second acoustic tube section (228). The elastic member (320) may seal the gap between the first protective member (216) and the second protective member (226) to reduce sound leakage through the fine gap between the first protective member (216) and the second protective member (226) when the electronic device (101) is folded.

[0237] According to one embodiment, the elastic member (320) can perform a cushioning role between the first housing (210) and the second housing (220) when folded. By having the cushioning role of the elastic member (320), damage between the display areas of the flexible display (203) that face each other when folded can be prevented. By having the cushioning role of the elastic member (320), damage between adjacent protective members (e.g., the first protective member (216) and the second protective member (226)) that come into contact with each other when folded can be prevented.

[0238] According to one embodiment, the electronic device (101) may include a second protective member (226). The second protective member (226) may be disposed on the outer edge of the flexible display (203). The second protective member (226) may be disposed on the upper side of the second display area (A2).

[0239] According to one embodiment, the second protective member (226) may include a through hole (2261). The through hole (2261) of the second protective member (226) may be formed to overlap with the inlet (2281) of the second acoustic tube (228). The through hole (2261) of the second protective member (226) may be connected to the second acoustic tube (228).

[0240] According to one embodiment, the second housing (220) may include a protrusion (2231). The protrusion (2231) may protrude toward the inside of the second acoustic tube (228). The protrusion (2231) may protrude toward the inside of the second acoustic tube (228) from a side member that includes a side surface of the second housing (220) adjacent to the second acoustic tube (228) (e.g., the second-third side surface (223)). By forming the protrusion (2231), the rigidity of the side member of the second housing (220) thinned by the second acoustic tube (228) may be improved.

[0241] According to one embodiment, the second protective member (226) may include a groove (2262) dug around the through hole (2261). The groove (2262) may be formed so that the upper side of the elastic member (320) is secured when the electronic device (101) is folded and the front surface of the first housing (210) and the front surface of the second housing (220) face each other. The groove (2262) may be a portion where the first rib (321) of the elastic member (320) is secured when the electronic device (101) is folded. By forming the groove (2262) in the second protective member (226), the first protective member (216) and the second protective member (226) can be brought into closer contact in the folded state, and as a result, the sound level can be effectively reduced.

[0242] In one embodiment, the outlet (2283) may include a receiver hole (2283a). A portion of the outlet (2283) may be covered by the sub-display (225). A portion of the outlet (2283) may be covered by an edge portion of the sub-display (225). The receiver hole (2283a) may refer to a space in the outlet (2283) that is not covered by the sub-display (225).

[0243] According to one embodiment, the protrusion (2231) may be positioned to overlap the receiver hole (2283a) front and back. By blocking the space between the inlet (2281) and the receiver hole (2283a), the protrusion (2231) can make it difficult for the user to visually check the receiver hole (2283a) from the outside. By configuring the receiver hole (2283a) so that it is not easily visible to the user, the aesthetic appeal of the side of the sub-display (225) can be improved.

[0244] According to some embodiments, the elastic member (320) may be coupled to the through hole (2261) of the second protective member (226) as illustrated. For example, the elastic member (320) may be placed on the front surface of the second housing (220). For example, the elastic member (320) may be placed to surround the rim of the through hole (2261) of the second protective member (226). For example, the elastic member (320) may be fitted into the through hole (2261) of the second protective member (226).

[0245] According to some embodiments, the elastic member (320) may be placed in each of the through hole (2161) of the first protective member (216) and the through hole (2261) of the second protective member (226), as illustrated.

[0254] Fig. 14 is a perspective view of the upper front surface of the second housing (220) with the second protective member (e.g., the second protective member (226) of Fig. 11) omitted. Fig. 15 is a perspective view of the upper rear surface of the second housing (220) with the sub-display (225) omitted. Fig. 16a is a perspective view of the state in which the sub-display (225) is arranged in Fig. 15.

[0255] According to one embodiment, the second acoustic pipe (228) may include an inlet (2281), a third acoustic pipe (2282), and an outlet (2283).

[0256] According to one embodiment, the width of the inlet (2281) of the second acoustic tube (228) may be smaller than the width of the outlet (2283) of the second acoustic tube (228). Here, the width may be a value measured with respect to a direction parallel to the length direction of the second-third side (223). The outlet (2283) may have a wider width than the inlet (2281). The receiver hole (2283a) may have a wider width than the inlet (2281).

[0257] As described, a sub-display (225) may be positioned on the rear of the second housing (220). The sub-display (225) may be positioned to cover a portion of the outlet (2283). Sound is diffused through the receiver hole (2283a), which is the portion not covered by the sub-display (225).

[0271] For configurations shown in FIGS. 19 and 20 that are substantially identical or similar to the configuration described above, the same reference numbers are used.

[0272] The structures illustrated in FIGS. 19 and 20 are exemplary for convenience of explanation, and the scope of the present disclosure is not limited by the illustrated shapes and structures.

[0273] Referring to FIGS. 19 and 20, an electronic device (e.g., the electronic device (101) of FIG. 1 or the electronic device (101) of FIGS. 2A, 2B, 3A, 3B, 3C, and 3D) may include a first housing (210), a second housing (220), a first protective member (216), a second protective member (226), an elastic member (320), and an adhesive member (330).

[0274] According to one embodiment, the electronic device (101) may further include a first magnetic body (1911) and a second magnetic body (1912). The first magnetic body (1911) and the second magnetic body (1912) may be arranged to be coupled to each other when the electronic device (101) is in a folded state (e.g., the state of FIG. 3a, FIG. 3b, FIG. 3c and FIG. 3d).

[0275] According to one embodiment, the first magnetic body (1911) may be placed in the first housing (210). The first magnetic body (1911) may be placed facing the front of the first housing (210). The first magnetic body (1911) may be placed on the upper part of the first housing (210). The first magnetic body (1911) may be received within the first housing (210) so as not to be seen from the outside.

[0277] According to one embodiment, when the electronic device (101) is folded, the first magnetic body (1911) and the second magnetic body (1912) can be brought into close contact with each other by magnetism. The first housing (210) and the second housing (220) can also be fixed more closely by the magnetic coupling between the first magnetic body (1911) and the second magnetic body (1912). The coupling between the first magnetic body (1911) and the second magnetic body (1912) strengthens the force pressing the elastic member (320), thereby more efficiently reducing the sound gap between the first acoustic tube (218) and the second acoustic tube (228).

[0278] FIG. 21 is a plan view of an electronic device according to one embodiment of the present disclosure.

[0279] The embodiments of FIG. 21 can be optionally combined with the embodiments of FIG. 1 to 20 and the embodiments of FIG. 22 to 23.

[0280] For configurations shown in FIG. 21 that are substantially identical or similar to the configuration described above, the same reference number is used.

[0281] The structure illustrated in FIG. 21 is exemplary for convenience of explanation, and the scope of the present disclosure is not limited by the illustrated shape and structure.

[0282] Referring to FIG. 21, an electronic device (e.g., the electronic device (101) of FIG. 1 or the electronic device (101) of FIGS. 2A, 2B, 3A, 3B, 3C, and 3D) may include a first housing (210), a second housing (220), a third housing (230), a first protective member (216), a second protective member (226), a third protective member (236), a first hinge structure (240), a second hinge structure (250), a flexible display (203), a speaker (310), an elastic member (320), and an adhesive member (330).

[0283] According to one embodiment, the electronic device (101) may further include a damper member (2110). The damper member (2110) may be positioned to attenuate impact between adjacent housings when the electronic device (101) is in a folded state (e.g., the states of FIGS. 3a, 3b, 3c, and 3d).

[0284] In one embodiment, the damper member (2110) may be made of an elastic material. The damper member (2110) may be made of the same material as the elastic member (320). The damper member (2110) may include an elastic material such as rubber, latex, silicone, or polyurethane. The material of the damper member (2110) is not limited thereto.

[0285] According to one embodiment, the damper member (2110) may include a first damper member (2111), a second damper member (2112), and a third damper member (2113). The first damper member (2111), the second damper member (2112), and the third damper member (2113) may be positioned at the edge of the front (201a) of the electronic device (101) when the electronic device (101) is in an unfolded state (e.g., the state of FIG. 2a and FIG. 2b). The first damper member (2111), the second damper member (2112), and the third damper member (2113) may be positioned adjacent to the corner area of ​​the front (201a) of the electronic device (101) when the electronic device (101) is in an unfolded state.

[0286] For example, the first damper member (2111) may be positioned at the lower edge of the first housing (210). For example, the second damper member (2112) may be positioned at the upper edge of the third housing (230). For example, the third damper member (2113) may be positioned at the lower edge of the third housing. The positions of the first damper member (2111), the second damper member (2112), and the third damper member (2113) are exemplary, and the illustrated arrangement structure does not limit the scope of the present disclosure.

[0287] According to one embodiment, the elastic member (320) can perform the role of a single damper member. The elastic member (320) can have the role of damping between the front of the first housing (210) and the front of the second housing (220) when the electronic device (101) is folded. By having the elastic member (320) perform the role of a single damper member, the number of damper members (2110) placed in the electronic device (101) can be reduced.

[0288] According to one embodiment, when the electronic device (101) is in a folded state, the elastic member (320) and the first damper member (2111) can damp between the first housing (210) and the second housing (220).

[0289] According to one embodiment, when the electronic device (101) is in a folded state, the second damper member (2112) and the third damper member (2113) can damp between the first housing (210) and the third housing (230).

[0290] FIGS. 22a and FIGS. 22b are drawings for illustrating tuning profiles applied in an unfolded state and a folded state, respectively, in an electronic device according to one embodiment of the present disclosure.

[0291] The embodiments of FIGS. 22a and 22b can be optionally combined with the embodiments of FIGS. 1 to 21 and the embodiments of FIG. 23.

[0292] Among the configurations illustrated in FIGS. 22a and 22b, the same reference numbers are used for configurations that are substantially the same or similar to the configuration described above.

[0293] The structures illustrated in FIGS. 22a and 22b are exemplary for convenience of explanation and the scope of the present disclosure is not limited by the illustrated shapes and structures. The tuning profiles illustrated in FIGS. 22a and 22b are exemplary for convenience of explanation and the illustrated tuning profiles are not limited by the scope of the present disclosure.

[0294] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1 or the electronic device (101) of FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, FIG. 3c and FIG. 3d) may include at least one processor (e.g., the processor (120) of FIG. 1) and a memory (e.g., the memory (130) of FIG. 1).

[0295] According to one embodiment, the electronic device (101) can operate the first speaker (311) using different tuning profiles in an unfolded state (e.g., the state of FIG. 2a and FIG. 2b) and a folded state (e.g., the state of FIG. 3a, FIG. 3b, FIG. 3c and FIG. 3d), respectively. The processor (120) of the electronic device (101) can operate the first speaker (311) using different tuning profiles in an unfolded state and a folded state, respectively. The memory (130) may include instructions that cause the processor (120) to operate the first speaker (311) using different tuning profiles in an unfolded state and a folded state of the electronic device (101).

[0296] According to one embodiment, the electronic device (101) can operate the first speaker (311) by applying the first tuning profile (2210) while in an unfolded state. The processor (120) can operate the first speaker (311) by applying the first tuning profile (2210) while the electronic device (101) is in an unfolded state. The memory (130) may include instructions that cause the processor (120) to operate the first speaker (311) using the first tuning profile (2210) while the electronic device (101) is in an unfolded state.

[0297] According to one embodiment, the electronic device (101) can operate the first speaker (311) by applying the second tuning profile (2220) when the electronic device (101) is in a folded state. For example, the electronic device (101) can operate the first speaker (311) by applying the second tuning profile (2220) when the electronic device (101) is in a folded state. The processor (120) can operate the first speaker (311) by applying the second tuning profile (2220) when the electronic device (101) is in a folded state. The memory (130) may include instructions that cause the processor (120) to operate the first speaker (311) by applying the second tuning profile (2220) when the electronic device (101) is in a folded state.

[0298] When a user makes a call while the electronic device (101) is in a folded state, the call sound output from the first speaker (311) may experience attenuation as it passes through the first acoustic tube (218) and the second acoustic tube (228), causing the sound volume to decrease. In order to compensate for the attenuated sound, the electronic device (101) according to one embodiment may perform control to operate the first speaker (311) using different tuning profiles for the unfolded state and the folded state of the electronic device (101).

[0299] When the first speaker (311) is used for calling purposes, optimization may be required in a frequency band of about 100 Hz to 4 kHz. When the sound output from the first speaker (311) is transmitted through the first acoustic tube (218) and the second acoustic tube (228), an attenuation phenomenon may occur noticeably in the high frequency band (e.g., 1 kHz to 3 kHz). The second tuning profile (2220) may be formed to compensate for the amount of attenuation for each frequency band compared to the first tuning profile (2210). For example, the amount by which the second tuning profile (2220) is compensated for compared to the first tuning profile (2210) in a range below 1 kHz may be smaller than the amount by which the second tuning profile (2220) is compensated for compared to the first tuning profile (2210) in a range exceeding 1 kHz. Here, the amount may refer to the average compensation amount in the corresponding frequency range. For example, the difference between the first tuning profile (2210) and the second tuning profile (2220) in the 1 kHz or lower range may be smaller than the difference between the first tuning profile (2210) and the second tuning profile (2220) in the 1 kHz or higher range. Here, the difference may refer to the average difference in the corresponding frequency range.

[0300] According to one embodiment, the data of the first tuning profile (2210) and the second tuning profile (2220) can be determined by experiment and stored in memory (130).

[0301] According to one embodiment, the first tuning profile (2210) can be applied in speaker mode (sound output mode), and the second tuning profile (2220) can be applied in receiver mode (telephone call mode) which outputs volume during a call while the electronic device (101) is closed.

[0302] FIG. 23 is a flowchart illustrating a control method for applying the tuning profiles shown in FIG. 22a and FIG. 22b.

[0303] The embodiment of FIG. 23 can be optionally combined with the embodiments of FIGS. 1 to 22b.

[0304] For configurations described in FIG. 23 that are substantially identical or similar to the aforementioned configuration, the same reference number is used.

[0305] The flowchart illustrated in FIG. 23 is exemplary for convenience of explanation, and the scope of the present disclosure is not limited to the control sequence of the illustrated flowchart. Other operations may be added in addition to the illustrated control operations.

[0306] Referring to FIG. 23, a method for controlling an electronic device (e.g., the electronic device (101) of FIG. 1 or the electronic devices (101) of FIGS. 2A, 2B, 3A, 3B, 3C, and 3D) may be performed by at least one processor (e.g., the processor (120) of FIG. 1). Commands related to the method for controlling the electronic device (101) illustrated in FIG. 23 may be stored in a memory (e.g., the memory (130) of FIG. 1).

[0307] According to one embodiment, a method for controlling an electronic device (101) may include an operation (2310) in which the electronic device (101) receives a sound output request. When the processor (120) receives the sound output request, the processor (120) may perform the following operations. Here, the sound output request may refer to a request to operate the first speaker (311) and / or the second speaker (312). The memory (130) may include instructions that cause the processor (120) to perform operations below operation 2320 when the sound output request is received.

[0308] According to one embodiment, a control method for an electronic device (101) may include an operation (2320) for determining whether the electronic device (101) is in a closed state (e.g., the state of FIG. 3a, FIG. 3b, FIG. 3c and FIG. 3d). A processor (120) may determine whether the electronic device (101) is in a closed state. A memory (130) may include instructions that cause the processor (120) to determine whether the electronic device (101) is in a closed state.

[0309] According to one embodiment, a control method for an electronic device (101) may include an operation (2330) of determining whether a phone call is in progress when it is determined that the electronic device (101) is in a closed state. A processor (120) may determine whether a phone call is in progress when it is determined that the electronic device (101) is in a closed state. A memory (130) may include instructions that cause the processor (120) to determine whether a phone call is in progress when it is determined that the electronic device (101) is in a closed state.

[0310] According to one embodiment, a control method for an electronic device (101) may include an operation (2350) of applying a second tuning profile (e.g., the second tuning profile (2220) of FIG. 22b) when it is determined in operation 2330 that a phone call is in progress. A processor (120) may apply the second tuning profile (2220) when it is determined that a phone call is in progress. A memory (130) may include instructions that cause the processor (120) to apply the second tuning profile (2220) when it is determined that a phone call is in progress. To compensate for the attenuation of volume by frequency band while passing through the first acoustic tube (218) and the second acoustic tube (228) when the electronic device (101) is in a folded state, a second tuning profile (2220) with a compensation value applied to the first tuning profile (2210) may be applied.

[0311] According to one embodiment, a control method for an electronic device (101) may include an operation (2350) of applying a first tuning profile (e.g., the first tuning profile (2210) of FIG. 22a) when it is determined in operation 2320 that the electronic device (101) is not in a closed state. A processor (120) may apply the first tuning profile (2210) when it is determined that the electronic device (101) is not in a closed state. A memory (130) may include instructions that cause the processor (120) to apply the first tuning profile (2210) when it is determined that the electronic device (101) is not in a closed state. When the electronic device (101) is in an open state, the sound output from the first speaker (311) is output to the outside through only the first sound tube (218), so the first tuning profile (2210), which has a lower output value than the second tuning profile (2220), may be applied.

[0312] According to one embodiment, a control method of an electronic device (101) may include an operation (2350) of applying a first tuning profile (2210) when it is determined in operation 2330 that a phone call is not in progress. A processor (120) may apply the first tuning profile (2210) when it is determined that a phone call is not in progress. A memory (130) may include instructions that cause the processor (120) to apply the first tuning profile (2210) when it is determined that a phone call is not in progress. If it is determined in operation 2330 that a phone call is not in progress, the first speaker (311) does not need to output sound through the receiver hole (2283a) and outputs through the first acoustic tube (2183) of the first acoustic tube section (218) through one side of the first housing (210) (e.g., the first-third side (213)), so a first tuning profile (2210) with a lower output value than the second tuning profile (2220) can be applied.

[0313] According to one embodiment, a method of controlling an electronic device (101) may include an operation (2360) of controlling a speaker (310) to output sound by applying a first tuning profile (2210) or a second tuning profile (2220). The processor (120) may control the speaker (310) to output sound by applying the first tuning profile (2210) or the second tuning profile (2220). The memory (130) may include instructions that cause the processor (120) to control the speaker (310) to output sound by applying the first tuning profile (2210) or the second tuning profile (2220).
