Description

[Technical Field]

[0001] The present invention relates to electronic devices, for example, electronic devices including speaker modules. [Background technology]

[0002] 2. Description of the Related Art With the development of electronic, information and communication technology, various functions are being integrated into a single electronic device. For example, a smartphone includes a function of a sound player, an image capture device, or an electronic organizer in addition to a communication function, and by installing additional applications, the smartphone can realize even more diverse functions. As the use of personal, portable electronic devices such as smartphones becomes more common, user demands for portability and ease of use are steadily increasing.

[0003] For example, in addition to voice communication in early wireless communications, demand for multimedia services via broadcasting or real-time streaming is also increasing rapidly. In order to realize electronic devices that are suitable for multimedia services while maintaining portability, competition in terms of image and sound quality is likely to intensify. Flexible displays can be folded or rolled up to be easily portable and can provide a larger screen than typical flat panel displays.

[0004] Ensuring sound quality in miniaturized electronic devices can be difficult. For example, in miniaturized electronic devices, it can be difficult to design and ensure a path that can transmit or radiate sound from a speaker module to an external space. In such acoustic transmission paths, sound pressure can leak through the gaps between different structures, degrading acoustic quality, or the leaked sound pressure can cause internal structures to vibrate, generating noise. Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide an electronic device that can suppress sound pressure leakage in an acoustic transmission path. Another object of the present invention is to provide an electronic device that can suppress or prevent the generation of noise due to leaked sound pressure. Another object of the present invention is to provide an electronic device that includes a stable arrangement of various components or structures while providing an acoustic transmission path. [Means for solving the problem]

The aforementioned a speaker module disposed on the other surface, the portion of the acoustic waveguide is defined as a space between the first display and the first support plate; The acoustic waveguide guides the sound output from the speaker module to adjacent to the acoustic waveguide the second display One side part of The device is characterized in that it is configured to radiate the radiation from the outside to the external space.

[0007] Also, an electronic device according to an embodiment of the present invention includes a first housing and a second housing configured to rotate relative to each other between a first position where the housings are disposed opposite each other and a second position where the housings extend from the first position by a specified angle relative 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; a first region disposed in the first housing; a second region disposed in the second housing and disposed opposite the first region at the first position; and a hinge module disposed corresponding to the region where the hinge module is disposed and connecting the first region and the second region. and a first display including a folding region for folding the first display into the second display, wherein one of the first housing and the second housing includes an acoustic waveguide, a first support plate configured to support either the first region or the second region while defining at least a portion of the acoustic waveguide on one side, 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, and the acoustic waveguide is configured to radiate sound output from the speaker module to an external space from one side of the second display. [Effects of the Invention]

[0008] According to the electronic device of the present invention, the speaker module and the display (e.g., the second display 303 in Figure 4) are arranged on one side of the first support plate, and an acoustic waveguide is provided in an area or space substantially isolated from the display, thereby preventing the sound or sound pressure transmitted through the acoustic waveguide from interfering with the display.

[0009] For example, an electronic device according to an embodiment of the present invention can prevent sound pressure from leaking out of an acoustic transmission path, thereby suppressing or preventing noise generation and providing good acoustic quality. In one embodiment, by locating the display in an area or space separated from the acoustic transmission path (e.g., acoustic waveguide), the design freedom for the display mounting structure can be improved, and a stable display mounting structure can be provided. In addition, it provides various advantages that are identified directly or indirectly throughout this specification. [Brief explanation of the drawings]

[0017] FIG. 1 illustrates an electronic device 100 in an unfolded state according to one embodiment of the present invention, and FIG. 2 illustrates the electronic device 100 of FIG. 1 in a folded state according to one embodiment of the present invention. In the following detailed description, an example will be given of a configuration in which a pair of housing structures (also referred to as "housings") are pivotally coupled by a hinge structure (also referred to as "hinge module"). However, it should be noted that such embodiments do not limit the electronic device according to embodiments of the present invention. For example, an electronic device according to one embodiment of the present invention may include three or more housing structures, and a "pair of housing structures" in the embodiments disclosed below may mean "two housing structures among the three or more housing structures that are rotatably coupled to each other."

[0018] Referring to FIG. 1, the electronic device 100 includes a pair of housing structures (110, 120) that are rotatably coupled via a hinge structure (e.g., hinge structure 164 in FIG. 3) so as to be folded relative to each other, a hinge cover 165 that covers the foldable portions 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 the space formed by the pair of housing structures (110, 120). In one embodiment, electronic device 100 includes a foldable housing in which a pair of housing structures (110, 120) are pivotally coupled from a folded position opposite each other to an unfolded position next to each other. In this specification, the surface on which the display 130 is disposed is defined as the front surface of the electronic device 100, and the surface opposite the front surface is defined as the rear surface of the electronic device 100. Furthermore, the surface surrounding the space between the front and rear surfaces is defined as the side surface of the electronic device 100 .

[0019] In one embodiment, the pair of housing structures (110, 120) includes a first housing structure (e.g., first housing) 110 including the sensor area 131d, a second housing structure (e.g., 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 shown in FIGS. 1 and 2, but may be implemented with other shapes or combinations and / or combinations of parts. For example, in other embodiments, the first housing structure 110 and the first rear cover 140 can be integrally formed, and the second housing structure 120 and the second rear cover 150 can be integrally formed. In another embodiment, the first housing structure 110 can include a first back cover 140 and the second housing structure 120 can include a second back cover 150 .

[0020] According to one embodiment, the first housing structure 110 and the second housing structure 120 are arranged on opposite sides of a first axis, e.g., a folding axis A, and have a generally symmetrical shape with respect to the folding axis A. In some embodiments, the first housing structure 110 and the second housing structure 120 pivot relative to the hinge structure 164 or the hinge cover 165 about different folding axes. For example, the first housing structure 110 and the second housing structure 120 may be pivotally coupled to the hinge structure 164 or the hinge cover 165, respectively, and can be rotated between a folded position opposite each other to a tilted position relative to each other or a spread-out position next to each other by rotating about the folding axis A or about a different folding axis, respectively.

[0021] As used herein, "positioned alongside each other" or "extending alongside each other" means that two structures (e.g., housings (110, 120)) are at least partially positioned next to each other, or at least the portions that are adjacent to each other are positioned in parallel. In some embodiments, "placed alongside one another" means that two structures are placed adjacent to one another and are arranged to look in parallel or the same direction. In the following detailed description, expressions such as "side by side" and "parallel" are used, which can be easily understood based on the shape and arrangement of structures by referring to the attached drawings, etc.

[0022] According to one embodiment, the first housing structure 110 and the second housing structure 120 are at different angles or distances from each other depending on whether the state of the electronic device 100 is in an extended state (extended state, flat state, or open state), a folding state, or an intermediate state. According to one embodiment, the first housing structure 110 differs from the second housing structure 120 in that it further includes a sensor area 131d in which various sensors are arranged, but other areas may have mutually symmetrical shapes. In another embodiment, the sensor area 131d may be further disposed in at least a portion of the second housing structure 120, or may be substituted therefor.

[0023] In one embodiment, the first housing structure 110 is connected to a hinge structure (e.g., hinge structure 164 in FIG. 3) when the electronic device 100 is in an unfolded state and includes a first surface 111 arranged to face the front of the electronic device 100, a second surface 112 facing in the opposite direction to the first surface 111, and a first side member 113 that surrounds at least a portion of the space between the first surface 111 and the second surface 112. In one embodiment, the first side member 113 includes a first side 113a arranged parallel to the folding axis A, a second side 113b extending from one end of the first side 113a in a direction perpendicular to the folding axis A, and a third side 113c extending from the other end of the first side 113a in a direction perpendicular to the folding axis A.

[0024] In describing the embodiments of the present invention, expressions such as "parallel" or "perpendicular" are used in relation to the arrangement of the above-mentioned sides, but depending on the embodiment, this may also mean "partially parallel" or "partially perpendicular." In some embodiments, terms such as "parallel" or "perpendicular" may be used to include an arrangement inclined at an angle of 10 degrees or less.

[0025] In one embodiment, the second housing structure 120 is connected to a hinge structure (e.g., hinge structure 164 in FIG. 3 ) and includes a third surface 121 arranged to face the front of the electronic device 100 when the electronic device 100 is in an unfolded state, a fourth surface 122 facing in the opposite direction to the third surface 121, and a second side member 123 that surrounds at least a portion of the space between the third surface 121 and the fourth surface 122. In one embodiment, the second side member 123 includes 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 surface 121 may be positioned to face the first surface 111 in the folded state. In some embodiments, the second side member 123 may be made of substantially the same shape or material as the first side member 113, although there may be some differences in the specific shape.

[0026] In one embodiment, the electronic device 100 includes a recess 101 formed to accommodate a display 130 via a structural form-fit between the first housing structure 110 and the second housing structure 120. The recess 101 has substantially the same size as the display 130 . In one embodiment, the recess 101 has two or more different widths in the direction perpendicular to the folding axis A due to the sensor area 131d. For example, the recess 101 has a first width W1 between a first portion 120a parallel to the folding axis A in the second housing structure 120 and a first portion 110a formed at the edge of the sensor area 131d in 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 parallel to the folding axis A, not corresponding to the sensor area 131d in the first housing structure 110. In this case, the second width W2 is formed to be longer than the first width W1.

[0027] For example, the recess 101 is formed to have a first width W1 formed from the first portion 110a of the first housing structure 110 having mutually asymmetric shapes to the first portion 120a of the second housing structure 120, and a second width W2 formed from the second portion 110b of the first housing structure 110 to the second portion 120b of the second housing structure 120 having mutually symmetric shapes. 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 example shown in the figure. In various embodiments, depending on the configuration of sensor area 131d or portions of first housing structure 110 and second housing structure 120 that have asymmetric shapes, recess 101 may have two or more different widths.

[0028] In one embodiment, at least a portion of first housing structure 110 and second housing structure 120 are formed from a metallic or non-metallic material having a rigidity selected to support display 130 . In another embodiment, at least a portion of first housing structure 110 and second housing structure 120 comprises an electrically conductive material. If the first housing structure 110 and the second housing structure 120 include a conductive material, the electronic device 100 transmits and receives radio waves using the portions of the first housing structure 110 and the second housing structure 120 made of the conductive material. For example, a processor or communication module of electronic device 100 may use portions of first housing structure 110 and second housing structure 120 to perform wireless communication.

[0029] In one embodiment, the sensor area 131d is formed adjacent one corner of the first housing structure 110 and has a predetermined area. However, the arrangement, shape, or size of the sensor area 131d is not limited to the example shown in the figure. For example, in another embodiment, the sensor area 131d may be provided in another corner of the first housing structure 110, or in any area between the upper and lower corners. In another embodiment, the sensor area 131d may be disposed in at least a portion of the second housing structure 120. In another embodiment, the sensor area 131d may be arranged to extend into the first housing structure 110 and the second housing structure 120.

[0030] In one embodiment, electronic device 100 includes components exposed on the front surface of electronic device 100 through sensor area 131d or through one or more openings in sensor area 131d, and performs various functions through these components. The components disposed in the sensor area 131d may include, for example, at least one of a front camera device, a proximity sensor, an illuminance sensor, an iris recognition sensor, an ultrasonic sensor, or an indicator.

[0031] In one embodiment, the first back cover 140 is disposed on the second side 112 of the first housing structure 110 and has a substantially rectangular periphery. In one embodiment, the edges of the first back cover 140 are at least partially enveloped by the first housing structure 110 . Similarly, the second rear cover 150 is disposed on the fourth surface 122 of the second housing structure 120 and has at least a portion of its edge enclosed by the second housing structure 120 . In the illustrated embodiment, the first rear cover 140 and the second rear cover 150 have substantially symmetrical shapes with respect to the folding axis A. In other embodiments, the first back cover 140 and the second back cover 150 may include a variety of different shapes. In yet another embodiment, the first rear cover 140 can be integrally formed with the first housing structure 110, and the second rear cover 150 can be integrally formed with the second housing structure 120.

[0032] In one embodiment, the first rear cover 140, the second rear cover 150, the first housing structure 110, and the second housing structure 120, through their interconnected structures, 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, the back of electronic device 100 has one or more components located or visually exposed. For example, one or more components or sensors are visually exposed through the first rear region 141 of the first rear cover 140 . In various embodiments, the sensor may include a proximity sensor, a rear camera device and / or a flash.

[0033] In another embodiment, at least a portion of the sub-display 152 may be visually exposed through the second rear region 151 of the second rear cover 150 . In some embodiments, the sub-display 152 may be disposed over substantially the entire area of ​​the second rear area 151 . According to one embodiment, the electronic device 100 includes a slit 153 provided in the second housing structure 120 . The slit 153 is configured to radiate sound to the outside space, for example, and in voice calls, functions as a sound hole that radiates the voice of the other party. In some embodiments, if the sensor arranged in the first rear region 141 is a camera module, in the folded state, as shown in FIG. 2, the camera module is configured to capture an image of a subject in a direction opposite to the direction in which the sub-display 152 outputs the screen.

[0034] The display 130 is disposed in a space formed by the pair of housing structures (110, 120). For example, the display 130 is seated in a recess (eg, recess 101 in FIG. 1) formed by the pair of housing structures (110, 120) and is positioned to occupy substantially most of the front surface of the electronic device 100. For example, the front surface of the electronic device 100 includes the display 130 and a portion of the first housing structure 110 adjacent to the display 130 (e.g., an edge region) and a portion of the second housing structure 120 (e.g., an edge region). In one embodiment, the rear surface of the electronic device 100 includes a first rear cover 140, a portion of the first housing structure 110 adjacent to the first rear cover 140 (e.g., an edge region), a second rear cover 150, and a portion of the second housing structure 120 adjacent to the second rear cover 150 (e.g., an edge region).

[0035] In one embodiment, display 130 refers to a display in which at least a portion of the area can be transformed into a flat or curved surface. In one embodiment, the display 130 includes a folding region 131c, a first region 131a arranged on one side (e.g., the right region of the folding region 131c) of the folding region 131c, and a second region 131b arranged on the other side (e.g., the left region of the folding region 131c) of the folding region 131c. For example, the first region 131 a is disposed on the first surface 111 of the first housing structure 110 , and the second region 131 b is disposed on the third surface 121 of the second housing structure 120 . For example, the display 130 extends from the first surface 111 through the hinge structure 164 of FIG. 3 to the third surface 121, and at least the region corresponding to the hinge structure 164 (e.g., the folding region 131c) is a flexible region that can be transformed from a flat shape to a curved shape.

[0036] In one embodiment, the area division of display 130 is exemplary, and display 130 is divided into multiple areas (eg, four or more, or two) depending on structure or function. As an example, in the embodiment shown in FIG. 1, folding region 131c extends along a vertical axis (e.g., the Y axis in FIG. 3) parallel to folding axis A, and the area of ​​display 130 is divided by folding region 131c or folding axis (A axis), but in other embodiments, display 130 can be divided into areas based on other folding regions (e.g., folding regions parallel to a horizontal axis (e.g., the X axis in FIG. 3)) or other folding axes (e.g., folding axes parallel to the X axis in FIG. 3). The above-mentioned display area division is merely a physical division by a pair of housing structures (110, 120) and a hinge structure (e.g., hinge structure 164 in Figure 3), and the display 130 essentially displays one full screen via the pair of housing structures (110, 120) and a hinge structure (e.g., hinge structure 164 in Figure 3).

[0037] According to one embodiment, the first region 131a and the second region 131b have a generally symmetrical shape about the folding region 131c. However, unlike the second region 131b, the first region 131a includes a notch region (e.g., the notch region 133 in FIG. 3) that provides the sensor region 131d, and in other regions, has a shape symmetrical to that of the second region 131b. For example, the first region 131a and the second region 131b include portions having symmetrical shapes and portions having asymmetrical shapes.

[0038] With further reference to FIG. 3, the hinge cover 165 is disposed between the first housing structure 110 and the second housing structure 120 and is configured to be able to cover internal components (e.g., the hinge structure 164 in FIG. 3). In one embodiment, the hinge cover 165 is covered by a portion of the first housing structure 110 and the second housing structure 120 or is exposed to the outside depending on the operating state of the electronic device 100 (extended state or folded state). The following describes the operation of the first housing structure 110 and the second housing structure 120 and each area of ​​the display 130 depending on the operating state (for example, the extended state and the folded state) of the electronic device 100.

[0039] In one embodiment, when electronic device 100 is in an extended state (e.g., the state of FIG. 1), first housing structure 110 and second housing structure 120 form a 180 degree angle, and first region 131a and second region 131b of the display are arranged to face in the same direction, e.g., to display screens in directions parallel to each other. The folding region 131c is formed on the same plane as the first region 131a and the second region 131b. In one embodiment, when electronic device 100 is in a folded state (eg, the state of FIG. 2), first housing structure 110 and second housing structure 120 are positioned opposite 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 form a narrow angle (e.g., between 0 and 10 degrees) with respect to each other and face each other. When the electronic device 100 is in a folded state (for example, the state shown in FIG. 2), at least a portion of the folding region 131c forms a curved surface having a predetermined curvature.

[0040] In one embodiment, when the electronic device 100 is in an intermediate state, the first housing structure 110 and the second housing structure 120 are positioned at a certain angle 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 form an angle that is larger than in the folded state and smaller than in the unfolded state. At least a portion of the folding region 131c is made up of a curved surface having a predetermined curvature, and the curvature at this time is smaller than that in the folded state.

[0041] FIG. 3 is an exploded perspective view of an electronic device 100 according to one embodiment of the present invention. Referring to FIG. 3, in this embodiment, the electronic device 100 includes 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 rear cover 140, and a second rear cover 150. Herein, display 130 is referred to as a display module or a display assembly.

[0042] The display 130 includes a display panel 131 (eg, a flexible display panel) and one or more plates 132 or layers upon which the display panel 131 sits. In one embodiment, the plate 132 is disposed between the display panel 131 and the support member assembly 160 . A display panel 131 is disposed on at least a portion of one surface of the plate 132 (for example, the surface in the Z direction in FIG. 3). The plate 132 is formed in a shape corresponding to the display panel 131 . For example, a portion of the plate 132 is formed in a shape corresponding to the notch region 133 of the display panel 131 .

[0043] The support member assembly 160 includes 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 that covers the hinge structure 164 when viewed from the outside, and a wiring member 163 (e.g., a flexible printed circuit board (FPCB)) that crosses the first support member 161 and the second support member 162. In one embodiment, the support member assembly 160 is disposed between the plate 132 and at least one printed circuit board 170 . As an example, the first support member 161 is disposed between the first region 131 a of the display 130 and the first printed circuit board 171 . The second support member 162 is disposed between the second region 131 b of the display 130 and the second printed circuit board 172 .

[0044] In one embodiment, the support member assembly 160 has the wiring member 163 and at least a portion of the hinge structure 164 disposed therein. The wiring member 163 is disposed in a direction that crosses the first support member 161 and the second support member 162 (for example, in the X-axis direction). The wiring member 163 is disposed in a direction (eg, X-axis direction) perpendicular to the folding axis (eg, Y-axis or folding axis A in FIG. 1) of the folding region 131c.

[0045] According to one embodiment, the hinge structure 164 includes a hinge module 164a, a first hinge plate 164b, and / or a second hinge plate 164c. In some embodiments, the hinge module 164a is interpreted to include the first hinge plate 164b and the second hinge plate 164c. In one embodiment, the first hinge plate 164b is mounted to the interior of the first housing structure 110 and the second hinge plate 164c is mounted to the interior of the second housing structure 120. In some embodiments, the first hinge plate 164b may be attached directly to the first support member 161 and the second hinge plate 164c may be attached directly to the second support member 162.

[0046] In another embodiment, the first hinge plate 164b (or the second hinge plate 164c) may be directly attached 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 in which the first hinge plate 164b (or the second hinge plate 164c) is attached inside the first housing structure 110 (or the second housing structure 120) may vary depending on the embodiment. In yet another embodiment, the hinge module 164a may be attached to a first hinge plate 164b and a second hinge plate 164c, with the second hinge plate 164c pivotally coupled to the first hinge plate 164b. For example, hinge module 164a forms a folding axis (e.g., folding axis A in FIG. 1), and first housing structure 110 and second housing structure 120 (or first support member 161 and second support member 162) rotate relative to each other substantially around folding axis A.

[0047] As described above, the at least one printed circuit board 170 includes a first printed circuit board 171 arranged on the first support member 161 side and a second printed circuit board 172 arranged on the second support member 162 side. The first printed circuit board 171 and the second printed circuit board 172 are disposed within 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 realizing various functions of the electronic device 100 can be mounted on the first printed circuit board 171 and the second printed circuit board 172.

[0048] In one embodiment, first housing structure 110 and second housing structure 120 are assembled together such that they are coupled to opposite sides of support member assembly 160 with display 130 coupled to support member assembly 160 . First housing structure 110 and second housing structure 120 are slidably coupled to opposite sides of support member assembly 160, for example, first support member 161 and second support member 162, respectively. The first support member 161 and the second support member 162 are substantially housed in the first housing structure 110 and the second housing structure 120, and according to an embodiment, can be interpreted as part of the first housing structure 110 and the second housing structure 120.

[0049] In one embodiment, the first housing structure 110 includes a first rotational support surface 114 and the second housing structure 120 includes a second rotational support surface 124 that corresponds to the first rotational support surface 114 . The first rotation support surface 114 and the second rotation support surface 124 include curved surfaces that correspond to the curved surfaces included in the hinge cover 165 . In one embodiment, when electronic device 100 is in an unfolded state (e.g., the state of FIG. 1), first rotation support surface 114 and second rotation support surface 124 cover hinge cover 165, and hinge cover 165 may not be exposed or may be minimally exposed on the back of 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 rotating support surface 114 and the second rotating support surface 124 rotate along the curved surfaces included in the hinge cover 165 to maximize exposure of the hinge cover 165 to the back of the electronic device 100.

[0050] It should be noted that in the above detailed description, ordinal numbers such as first housing structure 110, second housing structure 120, first side member 113, or second side member 123 are used merely to distinguish components, and that such ordinal numbers do not limit the present invention. For example, although the sensor area 131d is illustrated 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 arranged on the first rear cover 140 and the sub-display 152 is arranged on the second rear cover 150, but the first rear area 141 for arranging sensors etc. and the sub-display 152 for outputting the screen may both be arranged on either the first rear cover 140 or the second rear cover 150.

[0051] FIG. 4 is a cross-sectional structural view showing an electronic device 300 (e.g., electronic device 100 or housing (110, 120) in FIGS. 1 to 3) according to one embodiment of the present invention, and FIG. 5 is a partially enlarged plan view showing the back of housing 301 (e.g., housing structure (110, 120) in FIGS. 1 to 3) of electronic device 300 according to one embodiment of the present invention.

[0052] The electronic device 300 of the embodiment disclosed by Figures 4 and 5 may be, for example, either the first housing or the second housing (e.g., the first housing structure 110 or the second housing structure 120) of Figures 1 to 3. In some embodiments, the first housing structure 110 of Figures 1-3 may include the configuration of the electronic device 300 shown in Figure 4, and / or the second housing structure 120 of Figures 1-3 may include the configuration of the electronic device 300 shown in Figure 4. In another embodiment, the electronic device 300 of FIG. 4 can be interpreted as including a cut-away view of the second housing structure 120 taken along line C of FIG.

[0053] Referring to Figures 4 and 5, electronic device 300 includes a housing 301, a first display 302 (e.g., display 130 in Figure 1 or 3) disposed on the front of housing 301, a second display 303 (e.g., sub-display 152 in Figure 1 or 2) disposed on the back of the housing, and / or a speaker module 304 disposed between first display 302 and second display 303. In some embodiments, electronic device 300 may include multiple speaker modules, at least one of which functions as a loudspeaker for outputting sound in a multimedia mode for playing videos or music, and at least one other of the multiple speaker modules (e.g., speaker module 304) may selectively function as an earpiece speaker for outputting received sound in a voice call mode. In another embodiment, any one of the speaker modules can function as either a loudspeaker or an earpiece speaker depending on the operating mode of the electronic device 300 .

[0054] According to one embodiment, the speaker module 304 outputs sound in a direction toward the first display 302, and the output sound travels through an acoustic waveguide 341 provided in the internal space of the housing 301 and is emitted into the external space from one side of the second display 303. Here, the space surrounded by the housing 301, the first display 302, and / or the second display 303 is defined as the "internal space of the electronic device 300 and / or the housing 301," and the "external space" means the "space surrounding the electronic device 300 and / or the housing 301." In one embodiment, the speaker module 304 serves as a speaker for the earpiece that outputs received sound in voice call mode. According to another embodiment, in multimedia mode, the speaker module 304 can function as a loudspeaker and can be combined with other speaker modules (not shown) to provide stereo sound.

[0055] According to one embodiment, the direction in which sound is radiated into the external space is different from the direction in which the speaker module 304 outputs sound. In one embodiment, the direction in which sound is radiated into the external space is substantially opposite to the direction in which the speaker module 304 outputs sound and is the same as the direction in which the second display 303 outputs a screen. For example, when the direction in which the speaker module 304 outputs sound is defined as the "+Z direction," the sound is emitted into the external space along the -Z direction. In another embodiment, sound may be emitted in a direction oblique to the Z axis while still being emitted substantially in the -Z direction.

[0056] For example, the direction in which the acoustic waveguide 341 (e.g., the slit (153, 345) in Figures 1, 2, or 4) points can be defined by the design shape of the electronic device 300, but the direction in which the sound propagates into the external space can be defined in various ways. In some embodiments, when a camera module is positioned in the first rear region 141 of FIG. 1 or FIG. 2, the camera module may be configured to capture an image of a subject in an opposite or oblique direction relative to the direction in which sound is emitted into the external space via the acoustic waveguide 341 or the slit 345.

[0057] According to one embodiment, the electronic device 300 includes a first support plate 311 (e.g., any one of the support members (161, 162) in FIG. 3) disposed between the first display 302 and the speaker module 304, and the acoustic waveguide 341 is provided between the first display 302 and the first support plate 311. For example, the first support plate 311 defines at least a portion of the acoustic waveguide 341 on one side (eg, the side 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 passes through the first support plate 311 to provide sound to the acoustic waveguide 341 . For example, the acoustic waveguide 341 is isolated by the first support plate 311 from the space in which the speaker module 304 (or the second display 303) is disposed.

[0058] According to one embodiment, the housing 301 includes a first support plate 311 and a side bezel structure 313 . In some embodiments, "housing 301" refers to a structure that houses other mechanical structures (e.g., at least a portion of support member assembly 160 in FIG. 3) or electrical components (e.g., printed circuit board 170 in FIG. 3), in which case first display 302 or second display 303 is interpreted as part of housing 301. In another embodiment, the side bezel structures 313 may be construed as part of the first support plate 311 . According to one embodiment, the first support plate 311 is positioned substantially within the electronic device 300 (e.g., at least one of the housing structures (110, 120) of Figures 1 to 3) and is coupled to and integrally formed with the side bezel structure 313. The first support plate 311 is formed, for example, from a metallic material and / or a non-metallic (eg, polymeric) material.

[0059] The first display 302 is coupled to one side of the first support plate 311, and a speaker module 304 and / or a printed circuit board (e.g., printed circuit board 170 in Figure 3) is disposed between the other side and the second display 303. According to one embodiment, the side bezel structure 313 has a frame shape that substantially surrounds the space between the first display 302 and the second display 303 . In one embodiment, the side bezel structures 313 are formed from substantially the same material as the first support plate 311 . In another embodiment, the side bezel structure 313 at least partially comprises a conductive material, and the portion formed of the conductive material functions as a radiating conductor for transmitting and receiving wireless signals. In some embodiments, the side bezel structure 313 is disposed at least partially adjacent to an edge of the first display 302 or the second display 303 .

[0060] According to one embodiment, printed circuit board 170 may have various electrical / electronic components disposed thereon, such as a processor, memory, and / or interfaces. 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 communications processor. In one embodiment, the processor or communication module is mounted on an electronic component, such as an integrated circuit chip, and disposed on the printed circuit board 170 .

[0061] According to one embodiment, the first display 302 is disposed on one side of the first support plate 311 and is at least partially surrounded by a side bezel structure 313 . The acoustic waveguide 341 is disposed or formed at least partially in the space between the first display 302 and the first support plate 311 . The acoustic waveguide 341 is substantially defined as the space provided by the first support plate 311, and a portion of the acoustic waveguide 341 is 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 a side bezel structure 313 .

[0062] According to one embodiment, the first display 302 includes a first display panel 323 (eg, 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 can include a protective sheet 321 exposed to the external space to protect the first display panel 323 from the external environment. The protective sheet 321 can be made of, for example, a synthetic resin film or thin glass, and is substantially transparent, allowing the 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 Figures 1 to 3 (e.g., the first housing structure 110 and the second housing 120), the first display 302 is folded or rolled by including a folding region 131c.

[0063] According to one embodiment, the electronic device 300 may further include a decorative member 315 attached to the side bezel structure 313 . The decorative member 315 is disposed on the front of the electronic device 300 so as to wrap around the edge of the first display 302 . For example, the decorative member 315 can provide a decorative effect on the appearance of the electronic device 300 while protecting the edges of the primary display 302 .

[0064] According to one embodiment, the second display 303 is disposed on the other side of the first support plate 311 and is at least partially surrounded by a side bezel structure 313, and together with at least a portion of the housing 301 (e.g., the side bezel structure 313), defines or forms a slit 345 (e.g., slit 153 in Figure 1 or Figure 2). For example, a portion of the side bezel structure 313 is disposed adjacent to an edge of the secondary display 303 , and the slit 345 is substantially formed by the spacing between the side bezel structure 313 and the secondary display 303 .

[0065] According to one embodiment, the second display 303 includes a transparent plate 331 exposed to the external space and a second display panel 333 disposed on the inner surface of the transparent plate 331 . For example, the transparent plate 331 is bonded 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 is disposed between the transparent plate 331 and the first support plate 311. The transparent plate 331 may be made of a glass plate or a polymer plate containing various coating layers, and is substantially transparent, allowing the image output through the second display panel 333 to pass through.

[0066] According to one embodiment, the second display 303 extends substantially from the first display 302 and is positioned on the back of the electronic device 300 and / or housing 301 while wrapping around a portion of the side of the electronic device 300 and / or housing 301 (e.g., sides (113a, 113b, 113c, 123a, 123b, 123c) in Figure 1 or Figure 2). When the second display 303 is extended from the first display 302 , the transparent plate 331 can be made of substantially the same material or thickness as the protective sheet 321 . In another embodiment, in a structure in which the second display 303 extends from the first display 302, the thickness of the transparent plate 331 in the portion located on the side of the electronic device 300 and / or the housing 301 or in the portion located on the back of the electronic device and / or the housing may be different from the thickness of the protective sheet 321.

[0067] According to one embodiment, the electronic device 300 further includes a second support plate 317 . The second support plate 317 is disposed in the space between the speaker module 304 and the second display 303 and is configured to substantially support the second display 303 (eg, the second display panel 333). For example, the entire area of ​​the second display panel 333 is supported by the second support plate 317, and the shape of the flat plate is stably maintained. In one embodiment, the electronic device 300 further includes an elastic member 349 disposed between the second support plate 317 and the speaker module 304, which presses the speaker module 304 to closely contact the first support plate 311.

[0068] According to one embodiment, the speaker module 304 is provided on the other side of the first support plate 311, and the area in contact with the first support plate 311 is substantially sealed. For example, an elastic third adhesive member 395 (e.g., double-sided tape) is provided in the area where the speaker module 304 and the first support plate 311 contact each other, and the elastic force of the elastic member 349 causes the speaker module 304 to adhere closely to the third adhesive member 395 and / or the first support plate 311. The speaker module 304 outputs sound in a direction toward the first display 302 (for example, the +Z direction), and the output sound travels through the acoustic waveguide 341 and is radiated into the external space.

[0069] According to one embodiment, the acoustic waveguide 341 is configured to receive and radiate sound output by the speaker module 304 into an external space. According to one embodiment, the acoustic waveguide 341 has the form of a groove formed substantially by machining one surface of the first support plate 311 and is connected to the external space at a position adjacent to the edge of the first support plate 311. In some embodiments, the acoustic waveguide 341 may pass through a portion of the side bezel structure 313 and be coupled to the external space via a slit 345 . For example, at least a portion of the acoustic waveguide 341 refers to a space surrounded by the first support plate 311 and / or the side bezel structure 313 .

[0070] According to one embodiment, the acoustic waveguide 341 has an open area facing the first display 302 . Some of the open areas of the acoustic waveguide 341 are closed by the first display 302 and / or the dummy plate 329 . For example, another portion of the acoustic waveguide 341 is 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 while surrounding another portion of the acoustic waveguide 341. The dummy plate 329 is joined 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 by welding or fusion bonding.

[0071] According to one embodiment, the first support plate 311 includes an open area 343 formed through both sides. The opening area 343 is formed at a position substantially corresponding to the speaker module 304 , and the speaker module 304 provides sound to the acoustic waveguide 341 through the opening area 343 . The sound provided to the acoustic waveguide 341 travels sequentially through the acoustic waveguide 341, for example, through a space partially surrounded by the dummy plate 329 and a space partially formed by the side bezel structure 313, and is radiated into the external space through the slit 345. For example, acoustic waveguide 341 is configured to receive sound through open area 343 at one end and radiate sound to the external space through slit 345 at the other end.

[0072] As mentioned above, in the acoustic transmission or propagation path from the speaker module 304 to the external space (for example, the path provided by the acoustic waveguide 341), sound pressure may escape through gaps between structures. For example, around the acoustic waveguide 341, if there is a gap 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., the transparent plate 331), sound pressure may leak out. If sound pressure escapes through gaps between structures that are not the designated path (e.g., slits), distorted sound may be output that differs from the specifications or adjustment state of the speaker module 304. In another embodiment, when the escaping sound pressure flows into a space between structures (e.g., the space between the first support plate 311 and the second display 303), it can cause vibrations in parts of the structure, which can cause noise.

[0073] According to an embodiment of the present invention, it is possible to block sound pressure from leaking through a space other than a path designated inside the electronic device 300 . For example, the third adhesive member 395 can provide a sealing structure between the speaker module 304 and the first support plate 311, thereby blocking the outflow of sound pressure. The third adhesive member 395 has a closed curve shape that wraps around the periphery of the open region 343 on the other surface of the first support plate 311 . Similarly, the dummy plate 329 and the first support plate 311 are joined by a fourth adhesive member 397 and / or by welding or fusion bonding, thereby forming a seal structure between the dummy plate 329 and the first support plate 311 and preventing sound pressure from escaping.

[0074] In some embodiments, around the end of the acoustic waveguide 341 (eg, the slit 345 ), the transparent plate 331 is bonded to the first support plate 311 and / or the side bezel structure 313 by a second adhesive member 393 . For example, the second adhesive member 393 blocks 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 where the second adhesive member 393 is arranged (e.g., bonding area 339 in Figure 5) is arranged around the acoustic waveguide 341 (or slit 345) when viewed substantially from the Z-axis direction, and the second adhesive member 393 seals the gap between the transparent plate 331 and the first support plate 311 (or side bezel structure 313) around the acoustic waveguide 341.

[0075] According to one embodiment, the transparent plate 331 is arranged to overlap the acoustic waveguide 341 when viewed in the Z-axis direction. For example, the edge of the transparent plate 331 may be at least partially colored to make it opaque to light, and the shape in which the acoustic waveguide 341 is machined may be hidden by the colored portion of the transparent plate 331. Thereby, the slit 345 is defined by the first support plate 311 or the side bezel structure 313 and the second display 303 (eg, the transparent plate 331). In some embodiments, although described separately for ease of explanation, the opening area 343 or slit 345 may be substantially part of the acoustic waveguide 341, and the transparent plate 331 may define another part of the acoustic waveguide 341.

[0076] According to one embodiment, the second adhesive member 393 is arranged to form a closed curve substantially along the edge of the second display 303 . In another embodiment, the second display panel 333 is disposed within the area surrounded by the second adhesive member 393 . For example, the second adhesive member 393 seals the space enclosed by the second display 303 and the housing 301 (e.g., the first support plate 311 or the side bezel structure 313) from other spaces inside the electronic device 300 or from the external space.

[0077] According to one embodiment, between the second display 303 and the first support plate 311, the second support plate 317 separates the space in which the second display panel 333 is arranged from the space in which the speaker module 304 is arranged or the space in which the printed circuit board 170 of FIG. 3 is arranged. For example, the second support plate 317 shields the second display panel 333 from interference with other structures inside the electronic device 300 and supports substantially 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 are stably positioned while blocking sound pressure from flowing into the space between at least the first support plate 311 (or side bezel structure 313) and the second display 303, while protecting the second display panel 333 from other structures.

[0078] FIG. 6 is a cross-sectional view showing an electronic device 400 (for example, the electronic device (100, 300) of FIGS. 1 to 4) according to another embodiment of the present invention. The embodiment shown in FIG. 6 omits the dummy plate 329 of the embodiment shown in FIG. 4, and is configured to define a portion of the acoustic waveguide 341 as the first display 302 itself. Compared to the embodiment shown 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 because 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, for configurations that can be easily understood from the above-described embodiments, the reference numbers in the drawings may be given in the same manner or may be omitted, and detailed descriptions thereof may also be omitted.

[0079] According to one embodiment, the electronic device 400 further includes at least one fifth adhesive member ( 491 , 493 ) that attaches the first display 302 (eg, the first display panel 323 ) to the first support plate 311 . The fifth adhesive members (491, 493) are formed or arranged on one surface of the first support plate 311 so as to form a closed curve that surrounds the open portion of the acoustic waveguide 341. In some embodiments, the fifth adhesive member (491, 493) is fabricated as substantially a 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 described as an example, but the first adhesive member 391 itself can perform the function of the fifth adhesive member (491, 493).

[0080] According to one embodiment, the first display 302 (e.g., the first display panel 323) has sufficient rigidity to not be deformed by the acoustic sound pressure output from the speaker module 304, and is positioned to replace the dummy plate 329 of FIG. 4 between the opening region 343 and the slit 345, thereby defining a portion of the acoustic waveguide 341. In one embodiment, the first display panel 323 is attached to the first support plate 311 by the fifth adhesive members (491, 493) (and / or the first adhesive member 391), and in the area surrounded by the fifth adhesive members (491, 493), the first display panel 323 forms part of the inner wall of the acoustic waveguide 341.
