Description

Electronic device including a speaker module

[0001] Various embodiments disclosed in this document relate to electronic devices, for example, electronic devices including a speaker module.

[0002] With the advancement of electronics, information, and communication technologies, a variety of functions are being integrated into a single electronic device. For example, smartphones incorporate functions such as audio playback, imaging, and electronic notebooks in addition to communication functions. Furthermore, the installation of additional applications allows smartphones to offer even more diverse functions.

[0003] As the use of personal, portable electronic devices like smartphones becomes more widespread, user demand for portability and ease of use is steadily increasing. For example, demand is rapidly increasing not only for voice calls in early wireless communications, but also for multimedia services such as broadcasting and live streaming. Developing portable electronic devices suitable for multimedia services can intensify competition for image and audio quality. Flexible displays can transform into folded or rolled states, making them easy to carry while also providing a larger screen than typical flat-panel displays.

[0004] Ensuring sound quality in miniaturized electronic devices can be challenging. For example, it can be difficult to design and secure a path for transmitting or radiating sound from the speaker module to the external space. In this sound transmission path, sound pressure can leak through gaps between different structures, degrading sound quality. This leaked sound pressure can also cause internal structures to vibrate, generating noise.

[0005] Various embodiments disclosed in this document can provide an electronic device capable of suppressing sound pressure leakage in an acoustic transmission path.

[0006] Various embodiments disclosed in this document can provide an electronic device capable of suppressing or preventing noise generation due to leaked sound pressure.

[0007] Various embodiments disclosed in this document can provide an electronic device that includes a stable arrangement structure of various components or structures while providing an acoustic transmission path.

[0008] According to various embodiments disclosed in the present document, an electronic device includes an acoustic waveguide, a first support plate configured to define at least a portion of the acoustic waveguide on one side, a first display disposed on one side of the first support plate, a second display disposed on the other side of the first support plate, and a speaker module disposed on the other side of the first support plate between the first support plate and the second display, wherein the acoustic waveguide may be configured to radiate sound output from the speaker module to an external space from one side of the second display.

[0009] According to various embodiments disclosed in the present document, an electronic device includes a first housing and a second housing configured to rotate relative to each other between a first position facing each other and a second position unfolded from the first position by a specified angle with respect to each other, a hinge module disposed between the first housing and the second housing and rotatably connecting the first housing and the second housing, and a first display including a first region disposed in the first housing, a second region disposed in the second housing and facing the first region at the first position, and a folding region disposed corresponding to the region where the hinge module is disposed and connecting the first region and the second region, wherein one of the first housing and the second housing comprises an acoustic waveguide, a first support plate configured to support one of the first region and the second region while defining at least a portion of the acoustic waveguide on one surface, a second display disposed on the other surface of the first support plate, and a second display disposed between the first support plate and the second display on the other surface of the first support plate. A speaker module is included, and the acoustic waveguide can be configured to radiate sound output from the speaker module to an external space from one side of the second display.

[0010] According to various embodiments disclosed in the present document, when a speaker module and a display (e.g., the second display (303) of FIG. 4) are disposed on one side of a first support plate, an acoustic waveguide is provided in an area or space substantially isolated from the display, thereby preventing sound or sound pressure transmitted through the acoustic waveguide from interfering with the display. For example, an electronic device according to various embodiments can suppress or prevent the generation of noise and provide good sound quality by preventing sound pressure from leaking from the sound transmission path. In one embodiment, since the display is disposed in an area or space isolated from the sound transmission path (e.g., the acoustic waveguide), the design freedom for the display mounting structure can be improved, and a stable display mounting structure can be provided. In addition, various effects that can be directly or indirectly identified through the present document can be provided.

[0023] FIG. 1 is a drawing showing an unfolded state of an electronic device (100) according to various embodiments disclosed in this document. FIG. 2 is a drawing showing a folded state of the electronic device (100) of FIG. 1 according to various embodiments disclosed in this document.

[0024] In the detailed description below, a configuration in which a pair of housing structures (or, referred to as 'housings') are rotatably coupled by a hinge structure (or, referred to as 'hinge module') may be exemplified. However, it should be noted that this embodiment does not limit the electronic device according to various embodiments disclosed in the present document. For example, the electronic device according to various embodiments disclosed in the present document may include three or more housing structures, and "a pair of housing structures" in the embodiments disclosed below may mean "two housing structures rotatably coupled to each other among the three or more housing structures."

[0025] Referring to FIG. 1, an electronic device (100) may include a pair of housing structures (110, 120) that are rotatably coupled to each other via a hinge structure (e.g., hinge structure (164) of FIG. 3) so as to be folded with respect to each other, a hinge cover (165) that covers a foldable portion of the pair of housing structures (110, 120), and a display (130) (e.g., a flexible display or a foldable display) that is disposed in a space formed by the pair of housing structures (110, 120). In one embodiment, the electronic device (100) may include a foldable housing in which the pair of housing structures (110, 120) are rotatably coupled from a position where they are folded to face each other to a position where they are unfolded parallel to each other. In this document, the surface on which the display (130) is placed may be defined as the front surface of the electronic device (100), and the surface opposite the front surface may be defined as the back surface of the electronic device (100). Additionally, the surface surrounding the space between the front surface and the back surface may be defined as the side surface of the electronic device (100).

[0026] In one embodiment, a pair of housing structures (110, 120) may include a first housing structure (e.g., a first housing) (110) including a sensor area (131d), a second housing structure (e.g., a second housing) (120), a first rear cover (140), and a second rear cover (150). The pair of housing structures (110, 120) of the electronic device (100) are not limited to the shapes and combinations illustrated in FIGS. 1 and 2 and may be implemented by other shapes or combinations and / or combinations of parts. For example, in another embodiment, the first housing structure (110) and the first rear cover (140) may be formed integrally, and the second housing structure (120) and the second rear cover (150) may be formed integrally. In another embodiment, the first housing structure (110) may include a first rear cover (140), and the second housing structure (120) may include a second rear cover (150).

[0027] According to one embodiment, the first housing structure (110) and the second housing structure (120) may be arranged on both sides about a first axis, for example, a folding axis (A), and may have an overall symmetrical shape about the folding axis (A). In some embodiments, the first housing structure (110) and the second housing structure (120) may be rotatable about different folding axes with respect to the hinge structure (164) or the hinge cover (165). For example, the first housing structure (110) and the second housing structure (120) may be rotatably coupled to the hinge structure (164) or the hinge cover (165), respectively, and may be rotatable about the folding axis (A) or about different folding axes, thereby being rotatable between a position in which they are folded facing each other, a position inclined with respect to each other, or a position in which they are unfolded parallel to each other.

[0028] In this document, the phrase "positioned parallel to each other" or "extending parallel to each other" may mean a state in which two structures (e.g., housings (110, 120)) are positioned at least partially next to each other, or a state in which at least portions positioned next to each other are arranged in parallel. In some embodiments, the phrase "positioned parallel to each other" may mean that two structures are positioned next to each other and are arranged to face a parallel direction or the same direction. Although expressions such as "parallel" and "parallel" may be used in the detailed description below, this can be easily understood according to the shape or arrangement relationship of the structures by referring to the attached drawings, etc.

[0029] According to one embodiment, the first housing structure (110) and the second housing structure (120) may have different angles or distances from each other depending on whether the state of the electronic device (100) is an extended state (flat state or open state), a folded state, or an intermediate state. According to one embodiment, unlike the second housing structure (120), the first housing structure (110) additionally includes a sensor area (131d) in which various sensors are arranged, but may have a mutually symmetrical shape in other areas. In another embodiment, the sensor area (131d) may be additionally arranged in or replaced with at least a portion of the second housing structure (120).

[0030] In one embodiment, the first housing structure (110) may include a first side (111) that is connected to a hinge structure (e.g., hinge structure (164) of FIG. 3) when the electronic device (100) is in an unfolded state and is arranged to face the front of the electronic device (100), a second side (112) that faces in an opposite direction to the first side (111), and a first side member (113) that surrounds at least a portion of the space between the first side (111) and the second side (112). In one embodiment, the first side member (113) may include a first side (113a) that is arranged parallel to a folding axis (A), a second side (113b) that extends from one end of the first side (113a) in a direction perpendicular to the folding axis (A), and a third side (113c) that extends from the other end of the first side (113a) in a direction perpendicular to the folding axis (A). In describing various embodiments of the present invention, expressions such as "parallel" or "vertical" are used with respect to the arrangement relationship of the above-described aspects. However, depending on the embodiment, this may include the meaning of "partially parallel" or "partially perpendicular." In some embodiments, expressions such as "parallel" or "vertical" may include an inclined arrangement relationship within an angular range of 10 degrees or less.

[0031] In one embodiment, the second housing structure (120) may be connected to a hinge structure (e.g., the hinge structure (164) of FIG. 3) and may include a third side (121) arranged to face the front of the electronic device (100) when the electronic device (100) is in an unfolded state, a fourth side (122) facing in an opposite direction to the third side (121), and a second side member (123) surrounding at least a portion of the space between the third side (121) and the fourth side (122). In one embodiment, the second side member (123) may include a fourth side (123a) arranged parallel to the folding axis (A), a fifth side (123b) extending from one end of the fourth side (123a) in a direction perpendicular to the folding axis (A), and a sixth side (123c) extending from the other end of the fourth side (123a) in a direction perpendicular to the folding axis (A). In one embodiment, the third side (121) may be positioned to face the first side (111) in a folded state. In some embodiments, the second side member (123) may be manufactured with substantially the same shape or material as the first side member (113), although there may be some differences in specific shapes.

[0032] In one embodiment, the electronic device (100) may include a recess (101) formed to accommodate a display (130) through a structural shape combination of a first housing structure (110) and a second housing structure (120). The recess (101) may have substantially the same size as the display (130). In one embodiment, due to the sensor area (131d), the recess (101) may have two or more different widths in a direction perpendicular to the folding axis (A). For example, the recess (101) may have a first width (W1) between a first portion (120a) of the second housing structure (120) that is parallel to the folding axis (A) and a first portion (110a) formed at the edge of the sensor area (131d) of the first housing structure (110), and a second width (W2) formed by a second portion (120b) of the second housing structure (120) and a second portion (110b) that is parallel to the folding axis (A) and does not correspond to the sensor area (131d) of the first housing structure (110). In this case, the second width (W2) may be formed to be longer than the first width (W1). For example, the recess (101) may be formed to have a first width (W1) formed from a first portion (110a) of a first housing structure (110) having a mutually asymmetrical shape to a first portion (120a) of a second housing structure (120), and a second width (W2) formed from a second portion (110b) of a first housing structure (110) having a mutually symmetrical shape to a second portion (120b) of a second housing structure (120). In one embodiment, the first portion (110a) and the second portion (110b) of the first housing structure (110) may be formed to have different distances from the folding axis (A). The width of the recess (101) is not limited to the illustrated example. In various embodiments, the recess (101) may have two or more different widths due to the shape of the sensor area (131d) or the asymmetrical shape of the first housing structure (110) and the second housing structure (120).

[0033] In one embodiment, at least a portion of the first housing structure (110) and the second housing structure (120) may be formed of a metallic or non-metallic material having a rigidity selected to support the display (130). In another embodiment, at least a portion of the first housing structure (110) and the second housing structure (120) may include an electrically conductive material. When the first housing structure (110) and the second housing structure (120) include an electrically conductive material, the electronic device (100) may transmit and receive wireless radio waves using portions of the first housing structure (110) and the second housing structure (120) made of the electrically conductive material. For example, a processor or a communication module of the electronic device (100) may perform wireless communication using portions of the first housing structure (110) and the second housing structure (120).

[0034] In one embodiment, the sensor area (131d) may be formed to have a predetermined area adjacent to one corner of the first housing structure (110). However, the arrangement, shape, or size of the sensor area (131d) is not limited to the illustrated example. For example, in another embodiment, the sensor area (131d) may be provided at another corner of the first housing structure (110) or any area between the upper corner and the lower corner. In another embodiment, the sensor area (131d) may be arranged in at least a portion of the second housing structure (120). In another embodiment, the sensor area (131d) may be arranged to extend to the first housing structure (110) and the second housing structure (120). In one embodiment, the electronic device (100) may include components exposed on the front side of the electronic device (100) through the sensor area (131d) or through one or more openings provided in the sensor area (131d), and may perform various functions through these components. The components arranged in the sensor area (131d) may include, for example, at least one of a front camera device, a proximity sensor, an illumination sensor, an iris recognition sensor, an ultrasonic sensor, or an indicator.

[0035] In one embodiment, the first rear cover (140) can be disposed on the second side (112) of the first housing structure (110) and can have a substantially rectangular periphery. In one embodiment, the periphery of the first rear cover (140) can be at least partially wrapped by the first housing structure (110). Similarly, the second rear cover (150) can be disposed on the fourth side (122) of the second housing structure (120) and can have at least a portion of its periphery wrapped by the second housing structure (120).

[0036] In the illustrated embodiment, the first rear cover (140) and the second rear cover (150) may have substantially symmetrical shapes with respect to the folding axis (A). In other embodiments, the first rear cover (140) and the second rear cover (150) may include various different shapes. In yet another embodiment, the first rear cover (140) may be formed integrally with the first housing structure (110), and the second rear cover (150) may be formed integrally with the second housing structure (120).

[0037] In one embodiment, the first rear cover (140), the second rear cover (150), the first housing structure (110), and the second housing structure (120) may be coupled to each other to provide a space in which various components of the electronic device (100) (e.g., a printed circuit board, an antenna module, a sensor module, or a battery) may be placed. In one embodiment, one or more components may be placed or visually exposed on the rear surface of the electronic device (100). For example, one or more components or sensors may be visually exposed through the first rear area (141) of the first rear cover (140). In various embodiments, the sensors may include a proximity sensor, a rear camera device, and / or a flash. In another embodiment, at least a portion of the sub-display (152) may be visually exposed through the second rear area (151) of the second rear cover (150). In some embodiments, the sub-display (152) may be placed on substantially the entire area of ​​the second rear area (151). According to one embodiment, the electronic device (100) may include a slit (153) provided in the second housing structure (120). The slit (153) may be configured to, for example, radiate sound into the external space, and may function as an acoustic hole for radiating the other party's voice in a voice call. In some embodiments, when the sensor arranged in the first rear area (141) is a camera module, the camera module may be configured to capture an object in a direction opposite to the direction in which the sub-display (152) outputs a screen in a folded state as shown in FIG. 2.

[0038] The display (130) may be placed on a space formed by a pair of housing structures (110, 120). For example, the display (130) may be mounted in a recess (e.g., recess (101) of FIG. 1) formed by the pair of housing structures (110, 120) and may be placed to occupy substantially most of the front surface of the electronic device (100). For example, the front surface of the electronic device (100) may include the display (130) and a portion (e.g., an edge portion) of the first housing structure (110) adjacent to the display (130) and a portion (e.g., an edge portion) of the second housing structure (120). In one embodiment, the back of the electronic device (100) may include a first back cover (140), a portion (e.g., an edge portion) of a first housing structure (110) adjacent to the first back cover (140), a second back cover (150), and a portion (e.g., an edge portion) of a second housing structure (120) adjacent to the second back cover (150).

[0039] In one embodiment, the display (130) may refer to a display in which at least a portion of the display can be transformed into a flat or curved surface. In one embodiment, the display (130) may include a folding area (131c), a first area (131a) disposed on one side (e.g., a right area of ​​the folding area (131c)) relative to the folding area (131c), and a second area (131b) disposed on the other side (e.g., a left area of ​​the folding area (131c)). For example, the first area (131a) may be disposed on a first side (111) of the first housing structure (110), and the second area (131b) may be disposed on a third side (121) of the second housing structure (120). For example, the display (130) may extend from the first surface (111) to the third surface (121) through the hinge structure (164) of FIG. 3, and at least a region corresponding to the hinge structure (164) (e.g., folding region (131c)) may be a flexible region that can be transformed from a flat shape to a curved shape.

[0040] In one embodiment, the division of the regions of the display (130) is exemplary, and the display (130) may be divided into a plurality of regions (for example, four or more or two) depending on the structure or function. For example, in the embodiment illustrated in FIG. 1, the folding region (131c) extends in the direction of the vertical axis (for example, the Y-axis in FIG. 3) parallel to the folding axis (A), and the regions of the display (130) may be divided by the folding region (131c) or the folding axis (A-axis), but in other embodiments, the display (130) may be divided into regions based on another folding region (for example, a folding region parallel to the horizontal axis (for example, the X-axis in FIG. 3)) or another folding axis (for example, a folding axis parallel to the X-axis in FIG. 3). The division of the display area described above is merely a physical division by a pair of housing structures (110, 120) and a hinge structure (e.g., hinge structure (164) of FIG. 3), and in reality, the display (130) can display one entire screen through a pair of housing structures (110, 120) and a hinge structure (e.g., hinge structure (164) of FIG. 3).

[0041] According to one embodiment, the first region (131a) and the second region (131b) may have an overall symmetrical shape centered on the folding region (131c). However, unlike the second region (131b), the first region (131a) may include a notch region (e.g., the notch region (133) of FIG. 3) that provides a sensor region (131d), and may have a shape symmetrical with respect to the second region (131b) in other regions. For example, the first region (131a) and the second region (131b) may include a portion having a symmetrical shape and a portion having an asymmetrical shape.

[0042] Referring further to FIG. 3, the hinge cover (165) may be configured to be disposed between the first housing structure (110) and the second housing structure (120) so as to cover internal components (e.g., the hinge structure (164) of FIG. 3). In one embodiment, the hinge cover (165) may be covered by a portion of the first housing structure (110) and the second housing structure (120) or exposed to the outside, depending on the operating state of the electronic device (100) (an extended state or a folded state).

[0043] Hereinafter, the operation of the first housing structure (110) and the second housing structure (120) and each area of ​​the display (130) according to the operating state (e.g., extended state and folded state) of the electronic device (100) will be described.

[0044] In one embodiment, when the electronic device (100) is in an extended state (e.g., the state of FIG. 1), the first housing structure (110) and the second housing structure (120) form an angle of 180 degrees, and the first region (131a) and the second region (131b) of the display may be arranged to face the same direction, for example, to display the screen in a direction parallel to each other. In addition, the folding region (131c) may form the same plane as the first region (131a) and the second region (131b).

[0045] In one embodiment, when the electronic device (100) is in a folded state (e.g., the state of FIG. 2), the first housing structure (110) and the second housing structure (120) may be arranged to face each other. For example, when the electronic device (100) is in a folded state (e.g., the state of FIG. 2), the first region (131a) and the second region (131b) of the display (130) may form a narrow angle (e.g., between 0 and 10 degrees) with each other and face each other. When the electronic device (100) is in a folded state (e.g., the state of FIG. 2), the folding region (131c) may form a curved surface having at least a predetermined curvature.

[0046] In one embodiment, when the electronic device (100) is in an intermediate state, the first housing structure (110) and the second housing structure (120) may be arranged to form a certain angle with respect to each other, for example, a 90 degree or 120 degree angle. For example, in the intermediate state, the first region (131a) and the second region (131b) of the display (130) may form an angle that is greater than the angle in the folded state and less than the angle in the unfolded state. The folding region (131c) may be formed as a curved surface having at least a certain curvature, and the curvature at this time may be less than that in the folded state.

[0047] FIG. 3 is an exploded perspective view of an electronic device (100) according to various embodiments disclosed in this document.

[0048] Referring to FIG. 3, in one embodiment, the electronic device (100) may include a display (130), a support member assembly (160), at least one printed circuit board (170), a first housing or first housing structure (110), a second housing or second housing structure (120), a first back cover (140), and a second back cover (150). In this document, the display (130) may be referred to as a display module or a display assembly.

[0049] The display (130) may include a display panel (131) (e.g., a flexible display panel) and one or more plates (132) or layers on which the display panel (131) is mounted. In one embodiment, the plate (132) may be disposed between the display panel (131) and the support member assembly (160). The display panel (131) may be disposed on at least a portion of one surface of the plate (132) (e.g., a surface in the Z direction of FIG. 3). The plate (132) may be formed in a shape corresponding to the display panel (131). For example, a portion of the plate (132) may be formed in a shape corresponding to a notch region (133) of the display panel (131).

[0050] The support member assembly (160) may include a first support member (161), a second support member (162), a hinge structure (164) disposed between the first support member (161) and the second support member (162), a hinge cover (165) covering the hinge structure (164) when viewed from the outside, and a wiring member (163) (e.g., a flexible printed circuit board (FPCB)) crossing the first support member (161) and the second support member (162).

[0051] In one embodiment, a support member assembly (160) can be disposed between a plate (132) and at least one printed circuit board (170). For example, a first support member (161) can be disposed between a first region (131a) of the display (130) and a first printed circuit board (171). A second support member (162) can be disposed between a second region (131b) of the display (130) and a second printed circuit board (172).

[0052] In one embodiment, a wiring member (163) and at least a portion of a hinge structure (164) may be disposed within the support member assembly (160). The wiring member (163) may be disposed in a direction transverse to the first support member (161) and the second support member (162) (e.g., in the X-axis direction). The wiring member (163) may be disposed in a direction perpendicular to a folding axis (e.g., the Y-axis or the folding axis (A) of FIG. 1) of the folding region (131c) (e.g., in the X-axis direction).

[0053] According to various embodiments, the hinge structure (164) may include a hinge module (164a), a first hinge plate (164b), and / or a second hinge plate (164c). In some embodiments, the hinge module (164a) may be interpreted to mean including a first hinge plate (164b) and a second hinge plate (164c). In one embodiment, the first hinge plate (164b) may be mounted inside the first housing structure (110), and the second hinge plate (164c) may be mounted inside the second housing structure (120). In some embodiments, the first hinge plate (164b) may be directly mounted to the first support member (161), and the second hinge plate (164c) may be directly mounted to the second support member (162). In another embodiment, the first hinge plate (164b) (or the second hinge plate (164c)) may be directly mounted to another structure (e.g., the first rotational support surface (114) or the second rotational support surface (124)) within the first housing structure (110) (or the second housing structure (120)). For example, the structure to which the first hinge plate (164b) (or the second hinge plate (164c)) is mounted within the first housing structure (110) (or the second housing structure (120)) may vary depending on the embodiment. In another embodiment, the hinge module (164a) may be mounted to the first hinge plate (164b) and the second hinge plate (164c) to rotatably connect the second hinge plate (164c) to the first hinge plate (164b). For example, a folding axis (e.g., the folding axis (A) of FIG. 1) is formed by a hinge module (164a), and the first housing structure (110) and the second housing structure (120) (or the first support member (161) and the second support member (162)) can substantially rotate relative to each other about the folding axis (A).

[0054] At least one printed circuit board (170) may include a first printed circuit board (171) disposed on the first support member (161) side and a second printed circuit board (172) disposed on the second support member (162) side, as mentioned above. The first printed circuit board (171) and the second printed circuit board (172) may be disposed inside a space formed by the support member assembly (160), the first housing structure (110), the second housing structure (120), the first rear cover (140), and the second rear cover (150). Components for implementing various functions of the electronic device (100) may be mounted on the first printed circuit board (171) and the second printed circuit board (172).

[0055] In one embodiment, the first housing structure (110) and the second housing structure (120) may be assembled to each other so as to be coupled to both sides of the support member assembly (160) while the display (130) is coupled to the support member assembly (160). The first housing structure (110) and the second housing structure (120) may be slidably coupled to both sides of the support member assembly (160), for example, to the first support member (161) and the second support member (162), respectively. The first support member (161) and the second support member (162) are substantially accommodated in the first housing structure (110) and the second housing structure (120), and may be interpreted as a part of the first housing structure (110) and the second housing structure (120) according to an embodiment.

[0056] In one embodiment, the first housing structure (110) may include a first rotational support surface (114), and the second housing structure (120) may include a second rotational support surface (124) corresponding to the first rotational support surface (114). The first rotational support surface (114) and the second rotational support surface (124) may include curved surfaces corresponding to the curved surfaces included in the hinge cover (165).

[0057] In one embodiment, when the electronic device (100) is in an unfolded state (e.g., the state of FIG. 1), the first rotational support surface (114) and the second rotational support surface (124) may cover the hinge cover (165) so that the hinge cover (165) is not exposed or is minimally exposed to the rear of the electronic device (100). In one embodiment, when the electronic device (100) is in a folded state (e.g., the state of FIG. 2), the first rotational support surface (114) and the second rotational support surface (124) may rotate along a curve included in the hinge cover (165) so that the hinge cover (165) is maximally exposed to the rear of the electronic device (100).

[0058] In the detailed description above, the components are simply distinguished using ordinal numbers, such as the first housing structure (110), the second housing structure (120), the first side member (113), or the second side member (123), but it should be noted that the present invention is not limited by the description of such ordinal numbers. For example, although the sensor area (131d) is exemplified as being formed in the first housing structure (110), the sensor area (131d) may be formed in the second housing structure (120) or may be formed in both the first and second housing structures (110, 120). In another embodiment, a configuration is exemplified in which the first rear area (141) is disposed on the first rear cover (140) and the sub-display (152) is disposed on the second rear cover (150), but both the first rear area (141) for disposing sensors and the like and the sub-display (152) for outputting a screen may be disposed on either the first rear cover (140) or the second rear cover (150).

[0059] FIG. 4 is a cross-sectional diagram illustrating an electronic device (300) according to one of various embodiments disclosed in the present document (e.g., the electronic device (100) or housings (110, 120) of FIGS. 1 to 3). FIG. 5 is a plan view partially enlarged to illustrate the rear surface of a housing (301) of an electronic device (300) according to one of various embodiments disclosed in the present document (e.g., the housing structures (110, 120) of FIGS. 1 to 3).

[0060] The electronic device (300) of the embodiment disclosed through FIGS. 4 and 5 may be, for example, any one of the first housing or the second housing (e.g., the first housing structure (110) or the second housing structure (120)) of FIGS. 1 to 3. In some embodiments, the first housing structure (110) of FIGS. 1 to 3 may include the configuration of the electronic device (300) disclosed in FIG. 4, and / or the second housing structure (120) of FIGS. 1 to 3 may include the configuration of the electronic device (300) disclosed in FIG. 4. In another embodiment, the electronic device (300) of FIG. 4 may be interpreted as including a cutaway view of the second housing structure (120) along line C of FIG. 1.

[0061] Referring to FIGS. 4 and 5 , the electronic device (300) may include a housing (301), a first display (302) disposed on the front of the housing (301) (e.g., the display (130) of FIG. 1 or 3 ), a second display (303) disposed on the rear of the housing (e.g., the sub-display (152) of FIG. 1 or 2 ), and / or a speaker module (304) disposed between the first display (302) and the second display (303). In some embodiments, the electronic device (300) may include a plurality of speaker modules, and at least one of the plurality of speaker modules may function as a loudspeaker for outputting sound in a multimedia mode for playing a video or music, and at least one other of the plurality of speaker modules (e.g., the speaker module (304)) may selectively function as a speaker for a receiver for outputting a received sound in a voice call mode. In another embodiment, any one of the plurality of speaker modules may function as either a loudspeaker or a speaker for the receiver, depending on the operating mode of the electronic device (300).

[0062] According to various embodiments, the speaker module (304) outputs sound in a direction toward the first display (302), and the output sound may travel through an acoustic waveguide (341) provided in the internal space of the housing (301) and be radiated from one side of the second display (303) to the external space. Here, the space surrounded by the housing (301), the first display (302), and / or the second display (303) may be defined as the 'internal space of the electronic device (300) and / or the housing (301),' and the 'external space' may mean the 'space around the electronic device (300) and / or the housing (301). In one embodiment, the speaker module (304) may be provided as a speaker for a receiver that outputs a received sound in a voice call mode. According to another embodiment, in a multimedia mode, the speaker module (304) may function as a loudspeaker, and may be combined with another speaker module (not shown) to implement stereo sound.

[0063] According to various embodiments, the direction in which the sound is radiated into the external space may be different from the direction in which the speaker module (304) outputs the sound. In one embodiment, the direction in which the sound is radiated into the external space may be substantially the opposite direction in which the speaker module (304) outputs the sound, and may be the same direction in which the second display (303) outputs the screen. For example, when the direction in which the speaker module (304) outputs the sound is defined as the '+Z direction', the sound may be radiated into the external space along the -Z direction. In another embodiment, the sound may be radiated substantially in the -Z direction, but in a direction oblique to the Z axis. For example, the direction in which the acoustic waveguide (341) (e.g., the slits (153, 345) of FIG. 1, FIG. 2, or FIG. 4) is directed may be defined by the design shape of the electronic device (300), but the direction in which the sound propagates into the external space may be defined in various ways. In some embodiments, when a camera module is placed in the first rear area (141) of FIG. 1 or FIG. 2, the camera module may be configured to photograph a subject in a direction opposite to or inclined with respect to the direction in which sound is radiated into the external space through the acoustic waveguide (341) or the slit (345).

[0064] According to various embodiments, the electronic device (300) includes a first support plate (311) (e.g., any one of the support members (161, 162) of FIG. 3) disposed between a first display (302) and a speaker module (304), and an acoustic waveguide (341) may be provided between the first display (302) and the first support plate (311). For example, the first support plate (311) may define at least a portion of the acoustic waveguide (341) on one surface (e.g., a surface facing the first display (302)). In one embodiment, the speaker module (304) is disposed between the first support plate (311) and the second display (303) and may provide sound to the acoustic waveguide (341) by penetrating the first support plate (311). For example, the acoustic waveguide (341) may be isolated by the first support plate (311) from the space where the speaker module (304) (or the second display (303)) is placed.

[0065] According to various embodiments, the housing (301) may include a first support plate (311) and a side bezel structure (313). In some embodiments, the 'housing (301)' may mean a structure that accommodates another mechanical structure (e.g., at least a portion of the support member assembly (160) of FIG. 3) or an electrical component (e.g., a printed circuit board (170) of FIG. 3), in which case the first display (302) or the second display (303) may be interpreted as a part of the housing (301). In other embodiments, the side bezel structure (313) may be interpreted as a part of the first support plate (311). According to one embodiment, the first support plate (311) is substantially disposed inside the electronic device (300) (e.g., at least one of the housing structures (110, 120) of FIGS. 1 to 3) and may be connected to or formed integrally with the side bezel structure (313). The first support plate (311) may be formed of, for example, a metallic material and / or a non-metallic (e.g., a polymer) material. The first display (302) may be coupled to one surface of the first support plate (311), and a speaker module (304) and / or a printed circuit board (e.g., a printed circuit board (170) of FIG. 3) may be disposed between the other surface and the second display (303).

[0066] According to various embodiments, the side bezel structure (313) may have a frame shape that substantially surrounds the space between the first display (302) and the second display (303). In one embodiment, the side bezel structure (313) may be formed of substantially the same material as the first support plate (311). In another embodiment, the side bezel structure (313) may at least partially include an electrically conductive material, and the portion formed of the electrically conductive material may function as a radiation conductor for transmitting and receiving wireless signals. In some embodiments, the side bezel structure (313) may be disposed at least partially adjacent to an edge of the first display (302) or the second display (303).

[0067] According to various embodiments, various electrical / electronic components, such as a processor, memory, and / or interface, may be disposed on the printed circuit board (170). The processor may include, for example, one or more of a central processing unit, an application processor, a graphics processing unit, an image signal processor, a sensor hub processor, or a communication processor. In one embodiment, the processor or communication module may be mounted on an electronic component, such as an integrated circuit chip, and disposed on the printed circuit board (170).

[0068] According to various embodiments, the first display (302) may be disposed on one surface of the first support plate (311) while being at least partially surrounded by the side bezel structure (313). The acoustic waveguide (341) may be disposed or formed at least partially in the space between the first display (302) and the first support plate (311). The acoustic waveguide (341) may be substantially defined by the space provided by the first support plate (311), and a portion of the acoustic waveguide (341) may be defined by the first display (302) (or a dummy plate (329) described below). In another embodiment, another portion of the acoustic waveguide (341) may be defined by the side bezel structure (313).

[0069] According to various embodiments, the first display (302) may include a first display panel (323) (e.g., the display panel (131) of FIG. 3) attached to a first support plate (311) by a first adhesive member (391). The first adhesive member (391) may be, for example, an elastic double-sided tape. In some embodiments, the first display (302) may include a protective sheet (321) exposed to the external space, thereby protecting the first display panel (323) from the external environment. The protective sheet (321) may be formed of, for example, a synthetic resin film or a thin film glass and may be substantially transparent to allow a screen output by the first display panel (323) to pass through. For example, when the electronic device (300) is provided as at least one of the housings of FIGS. 1 to 3 (e.g., the first housing structure (110) and the second housing (120)), the first display (302) can be folded or rolled by including a folding area (131c).

[0070] According to various embodiments, the electronic device (300) may further include a decorative member (315) mounted on the side bezel structure (313). The decorative member (315) may be positioned to surround the edge of the first display (302) on the front of the electronic device (300). For example, the decorative member (315) may provide a decorative effect on the exterior of the electronic device (300) while protecting the edge of the first display (302).

[0071] According to various embodiments, the second display (303) may be disposed on the other surface of the first support plate (311) and at least partially surrounded by the side bezel structure (313), and may define or form a slit (345) (e.g., the slit (153) of FIG. 1 or 2) together with at least a portion of the housing (301) (e.g., the side bezel structure (313)). For example, a portion of the side bezel structure (313) may be disposed adjacent to an edge of the second display (303), and the slit (345) may be formed substantially by a gap between the side bezel structure (313) and the second display (303).

[0072] According to various embodiments, the second display (303) may include a transparent plate (331) exposed to the external space, and a second display panel (333) disposed on an inner surface of the transparent plate (331). For example, the transparent plate (331) may be coupled to the first support plate (311) and / or the side bezel structure (313) by a second adhesive member (393), and the second display panel (333) may be disposed between the transparent plate (331) and the first support plate (311). The transparent plate (331) may be formed of a glass plate or a polymer plate including various coating layers, and may be substantially transparent to allow a screen output through the second display panel (333) to be transmitted.

[0073] According to various embodiments, the second display (303) may be disposed on the rear surface of the electronic device (300) and / or the housing (301) while substantially extending from the first display (302) and surrounding a portion of a side surface (e.g., side surfaces 113a, 113b, 113c, 123a, 123b, 123c of FIG. 1 or 2) of the electronic device (300). When the second display (303) extends from the first display (302), the transparent plate (331) may be formed of substantially the same material or with the same thickness as the protective sheet (321). In another embodiment, in a structure where the second display (303) extends from the first display (302), the thickness of the transparent plate (331) in the portion disposed on the side of the electronic device (300) and / or the housing (301) or in the portion disposed on the rear of the electronic device and / or the housing may be different from that of the protective sheet (321).

[0074] According to various embodiments, the electronic device (300) may further include a second support plate (317). The second support plate (317) may be disposed in a space between the speaker module (304) and the second display (303) and may be configured to substantially support the second display (303) (e.g., the second display panel (333)). For example, the entire area of ​​the second display panel (333) may be supported by the second support plate (317), thereby stably maintaining a flat shape. In one embodiment, the electronic device (300) may further include an elastic member (349) disposed between the second support plate (317) and the speaker module (304), and the elastic member (349) may press the speaker module (304) to bring it into close contact with the first support plate (311).

[0075] According to various embodiments, the speaker module (304) is provided on the other surface of the first support plate (311), and an area in contact with the first support plate (311) may be substantially sealed. For example, an elastic third adhesive member (395) (e.g., double-sided tape) may be provided in an area in which the speaker module (304) and the first support plate (311) are in contact, and the speaker module (304) may be brought into close contact with the third adhesive member (395) and / or the first support plate (311) by the elastic force of the elastic member (349). The speaker module (304) may output sound in a direction toward the first display (302) (e.g., +Z direction), and the output sound may travel through an acoustic waveguide (341) and be radiated into the external space.

[0076] According to various embodiments, the acoustic waveguide (341) may be configured to receive sound output from the speaker module (304) and radiate it to an external space. According to one embodiment, the acoustic waveguide (341) may have a groove shape formed substantially by processing one surface of the first support plate (311) and may be connected to the external space at a position adjacent to an edge of the first support plate (311). In some embodiments, the acoustic waveguide (341) may penetrate a portion of the side bezel structure (313) and be connected to the external space through a slit (345). For example, at least a portion of the acoustic waveguide (341) may refer to a space surrounded by the first support plate (311) and / or the side bezel structure (313).

[0077] According to various embodiments, the acoustic waveguide (341) may have a portion open facing the first display (302). The open portion of the acoustic waveguide (341) may be closed by the first display (302) and / or the dummy plate (329). For example, another portion of the acoustic waveguide (341) may be defined by the first display (302) and / or the dummy plate (329). In the illustrated embodiment, the electronic device (300) further includes a dummy plate (329), which may be positioned or attached to the first support plate (311) so as to surround another portion of the acoustic waveguide (341). The dummy plate (329) may be bonded to the first support plate (311) by a fourth adhesive member (397), such as an adhesive or an elastic double-sided tape. In some embodiments, the dummy plate (329) may be joined to the first support plate (311) in a manner such as welding or fusion.

[0078] According to various embodiments, the first support plate (311) may include an opening region (343) formed to penetrate both surfaces. The opening region (343) is formed at a position substantially corresponding to the speaker module (304), and the speaker module (304) may provide sound to the acoustic waveguide (341) through the opening region (343). The sound provided to the acoustic waveguide (341) may sequentially travel through the acoustic waveguide (341), for example, a space partially surrounded by the dummy plate (329) and a space partially formed in the side bezel structure (313), and may be radiated to an external space through the slit (345). For example, the acoustic waveguide (341) may be configured to receive sound through the opening region (343) at one end and radiate sound to an external space through the slit (345) at the other end.

[0079] As mentioned above, sound pressure may leak through gaps between structures in a sound transmission or propagation path (e.g., a path provided by an acoustic waveguide (341)) from the speaker module (304) to the external space. For example, if a gap exists around the acoustic waveguide (341), between the speaker module (304) and the first support plate (311), between the first support plate (311) and the dummy plate (329), and / or between the first support plate (311) (or the side bezel structure (313)) and the second display (303) (e.g., a transparent plate (331)), sound pressure may leak. If sound pressure leaks through gaps between structures other than a designated path (e.g., a slit), distorted sound that is different from the specifications or tuning state of the speaker module (304) may be output. In another embodiment, if the leaked negative pressure flows into the space between the structures (e.g., the space between the first support plate (311) and the second display (303), vibrations may occur in some of the structures, which may cause noise.

[0080] According to various embodiments disclosed in this document, sound pressure can be prevented from leaking through a gap other than a designated path inside the electronic device (300). For example, the third adhesive member (395) can prevent sound pressure from leaking by providing a sealing structure between the speaker module (304) and the first support plate (311). The third adhesive member (395) can have a closed curve shape that surrounds the perimeter of the opening area (343) on the other surface of the first support plate (311). Similarly, the dummy plate (329) and the first support plate (311) can be joined by the fourth adhesive member (397) and / or by welding or fusion, thereby forming a sealing structure between the dummy plate (329) and the first support plate (311), thereby preventing sound pressure from leaking. In some embodiments, the transparent plate (331) may be bonded to the first support plate (311) and / or the side bezel structure (313) around an end of the acoustic waveguide (341) (e.g., a slit (345)) by a second adhesive member (393). For example, the second adhesive member (393) may block sound pressure from entering the space between the transparent plate (331) and the first support plate (311) (or the side bezel structure (313)). For example, the bonding area (e.g., bonding area (339) of FIG. 5) where the second adhesive member (393) is placed is substantially positioned around the periphery of the acoustic waveguide (341) (or slit (345)) when viewed in the Z-axis direction, and the second adhesive member (393) can seal the gap between the transparent plate (331) and the first support plate (311) (or side bezel structure (313)) around the acoustic waveguide (341).

[0081] According to various embodiments, when viewed in the Z-axis direction, the transparent plate (331) may be arranged to partially overlap with the acoustic waveguide (341). For example, the edge of the transparent plate (331) may be at least partially colored to not transmit light, and the processed shape of the acoustic waveguide (341) may be concealed by the colored portion of the transparent plate (331). Thus, the slit (345) may be defined by the first support plate (311) or the side bezel structure (313) and the second display (303) (e.g., the transparent plate (331)). In some embodiments, although described separately for convenience of explanation, the opening area (343) or the slit (345) may be substantially a part of the acoustic waveguide (341), and the transparent plate (331) may define another part of the acoustic waveguide (341).

[0082] According to various embodiments, the second adhesive member (393) may be arranged to form a closed curve substantially along the edge of the second display (303). In another embodiment, the second display panel (333) may be arranged within an area surrounded by the second adhesive member (393). For example, a space surrounded by the second display (303) and the housing (301) (e.g., the first support plate (311) or the side bezel structure (313)) by the second adhesive member (393) may be sealed against another space within the electronic device (300) or an external space.

[0083] According to various embodiments, between the second display (303) and the first support plate (311), the second support plate (317) can isolate the space where the second display panel (333) is arranged from the space where the speaker module (304) is arranged or the space where the printed circuit board (170) of FIG. 3 is arranged. For example, the second support plate (317) can block the second display panel (333) from interfering with other structures inside the electronic device (300) and can substantially support the entire area of ​​the second display panel (333). In this way, the arrangement structure of the acoustic waveguide (341) and / or the arrangement structure of the second display (303) can stably arrange the second display panel (333) while blocking sound pressure from flowing into the space between at least the first support plate (311) (or the side bezel structure (313)) and the second display (303) and protecting the second display panel (333) from other structures.

[0084] FIG. 6 is a cross-sectional diagram illustrating an electronic device (400) (e.g., the electronic device (100, 300) of FIGS. 1 to 4) according to another one of the various embodiments disclosed in this document.

[0085] The embodiment disclosed in FIG. 6 may be configured such that the dummy plate (329) of the embodiment disclosed in FIG. 4 is omitted and the first display (302) itself defines a portion of the acoustic waveguide (341). Compared to the embodiment disclosed in FIG. 4, in the electronic device (400) of FIG. 6, the thickness (t1, t2) of the first support plate (311) may be partially increased as the dummy plate (329) is omitted. For example, compared to the electronic device (300) of FIG. 4, in the electronic device (400) of FIG. 6, the thickness of the first support plate (311) is at least partially increased, thereby improving the mechanical strength of the electronic device (400). In the following detailed description, reference numerals in the drawings may be used interchangeably with or omitted for configurations that can be easily understood through the above-described embodiments, and detailed descriptions thereof may also be omitted.

[0086] According to various embodiments, the electronic device (400) may further include at least one fifth adhesive member (491, 493) that attaches the first display (302) (e.g., the first display panel (323)) to the first support plate (311). The fifth adhesive member (491, 493)(s) may be formed or arranged to form a closed curve surrounding an open portion of the acoustic waveguide (341) on one surface of the first support plate (311). In some embodiments, the fifth adhesive member (491, 493)(s) may be manufactured as a substantially single body ('single body' or 'one-piece') with the first adhesive member (391). For example, in this embodiment, a fifth adhesive member (491, 493) separate from the first adhesive member (391) is exemplified and described, but the first adhesive member (391) itself can perform the function of the fifth adhesive member (491, 493).

In one embodiment, the first display panel (323) may be attached to the first support plate (311) by the fifth adhesive member (491, 493) (and / or the first adhesive member (391)), and the first display panel (323) may form a portion of the inner wall of the sound waveguide (341) in the area surrounded by the fifth adhesive member (491, 493). According to one embodiment, the fifth adhesive member (491, 493) can form a closed curve substantially surrounding the open portion of the acoustic waveguide (341) on one surface of the first support plate (311). For example, the fifth adhesive member (491, 493) can form a sealing structure between the first support plate (311) and the first display (302) (e.g., the first display panel (323)), thereby blocking sound pressure from leaking out.
