[0025] Hereinafter, embodiments of the present disclosure are described in detail with reference to the drawings so that those skilled in the art can easily practice them. However, the present disclosure may be embodied in various different forms and is not limited to the embodiments described herein. In relation to the description of the drawings, the same or similar reference numerals may be used for identical or similar components. Furthermore, in the drawings and related descriptions, descriptions of well-known functions and configurations may be omitted for clarity and brevity.

[0026] FIG. 1a illustrates an example of a first state of a foldable electronic device.

[0027] FIG. 1b illustrates an example of a second state of a foldable electronic device.

[0028] FIG. 1c illustrates an example of a third state of a foldable electronic device.

[0029] Referring to FIGS. 1a, 1b, and 1c, a foldable electronic device (100) may include a housing structure (101), a flexible display (140) (which may be described as a foldable display (140) or a main display (140)), a first hinge structure (150), a second hinge structure (160), and a display (170) (which may be described as a sub-display (170)). The housing structure (101) may include a first housing part (110), a second housing part (120), and a third housing part (130).

[0030] The first housing part (110) can be rotatably coupled to the second housing part (120) by the first hinge structure (150). The second housing part (120) and the first housing part (110) can be rotated about the first hinge structure (150). While the first housing part (110) is rotated about the first hinge structure (150), the second housing part (120) can be rotated about the first hinge structure (150). For example, when the second housing part (120) and the first housing part (110) are rotated about the first hinge structure (150), the angular displacement of the second housing part (120) may be substantially the same as the angular displacement of the first housing part (110).

[0031] The third housing part (130) can be rotatably coupled to the second housing part (120) by the second hinge structure (160). The second housing part (120) and the third housing part (130) can be rotated about the second hinge structure (160). While the second housing part (120) is rotated about the second hinge structure (160), the third housing part (130) can be rotated about the second hinge structure (160). For example, when the second housing part (120) and the third housing part (130) are rotated about the second hinge structure (160), the angular displacement (or angular change) of the second housing part (120) may be substantially the same as the angular displacement of the third housing part (130).

[0032] The first hinge structure (150) and the second hinge structure (160) can change the state of the foldable electronic device (100). The first hinge structure (150) and the second hinge structure (160) can provide (or enable) a first state (100a) of the foldable electronic device (100) (or a first state (100a) of the housing structure (101). The first state (101) of the foldable electronic device (100) (or a first state (100a)) of the housing structure (101) can be described as an unfolded state (or unfolded state) of the foldable electronic device (100) (or housing structure (101)). In the first state (100a), the front of the first housing part (110), the front of the second housing part (120), and the front of the third housing part (130) may define the front of the foldable electronic device (100). In the first state (100a), the front of the first housing part (110), the front of the second housing part (120), and the front of the third housing part (130) may face in the same direction. In the first state (100a), the foldable electronic device (100) may provide the user with a large display area of ​​the flexible display (140).

[0033] The first hinge structure (150) and the second hinge structure (160) can provide a second state (100b) of the foldable electronic device (100). The second state (100b) of the foldable electronic device (100) can be described as a state in which the foldable electronic device (100) is partially folded and partially unfolded (or a single folding state or a half folding state). For example, in the second state (100b), the front of the second housing part (120) and the front of the third housing part (130) may face in the same direction, and the front of the first housing part (110) and the front of the second housing part (120) may face in opposite directions. For example, in the second state (100b), the first housing part (110) and the second housing part (120) may be folded, and the second housing part (120) and the third housing part (130) may be unfolded. In the second state (100b), the foldable electronic device (100) can provide visual information through a part of the flexible display (140) (e.g., a third display area (140c)).

[0034] A foldable electronic device (100) can change from a first state (100a) to a third state (100c) through a second state (100b). The foldable electronic device (100) can change from a first state (100a), which is an unfolded state, to a second state (100b), which is a partially unfolded state. For example, the foldable electronic device (100) can change from a first state (100a), in which the first housing part (110), the second housing part (120), and the third housing part (130) face the same direction, to a second state (100b), in which the front of the first housing part (110) faces the front of the second housing part (120). The foldable electronic device (100) can change from a second state (100b), which is a partially unfolded state, to a third state (100c), which is a folded state. For example, when changing from the second state (100b) to the third state (100c), the folded first housing part (110) and the second housing part (120) can be placed on the third housing part (130).

[0035] The first hinge structure (150) and the second hinge structure (160) can provide a third state (100c) of the foldable electronic device (100) (or a third state (100c) of the housing structure (101). The third state (100c) of the foldable electronic device (100) (or a third state (100c) of the housing structure (101)) can be described as a folded state (or a folded state or a multi-folded state) of the foldable electronic device (100) (or the housing structure (101)). In the third state (100c), the front of the first housing part (110) and the front of the second housing part (120) may face in opposite directions, and the front of the second housing part (120) and the front of the third housing part (130) may face in opposite directions. In the third state (100c), the front of the first housing part (110) and the front of the third housing part (130) may face each other in the same direction. For example, in the third state (100c), the front of the second housing part (120) may face the front of the first housing part (110), and the front of the third housing part (130) may face the rear of the first housing part (110). In the third state (100c), the rear of the second housing part (120) may be exposed to the outside. A display (170) may be placed on the rear of the second housing part (120). In the third state (100c), the rear of the third housing part (130) may be exposed to the outside. A camera (175) may be placed on the rear of the third housing part (130). In the third state (100c), the foldable electronic device (100) can be folded to improve portability and can provide visual information through a display (170) placed on the rear of the second housing part (120).

[0036] The foldable electronic device (100) may further include a key button (139). The key button (139) may be exposed from a structure (e.g., an opening) formed on the side of the third housing part (130) and may partially protrude outside the foldable electronic device (100). The key button (139) may provide physical input to a processing circuit inside the foldable electronic device (100) by pressure transmitted from the outside. The key button (139) may not be included in the foldable electronic device (100) and may be implemented in another form, such as a soft key displayed on a flexible display (140) or a display (170).

[0037] The key button (139) may be positioned on the side of the third housing part (130) so as to be exposed to the outside in the third state (100c). As the key button (139) is positioned on the side of the third housing part (130), it may be positioned in the direction in which the side of the third housing part (130) faces. Even if the display (170) in the third state (100c) is changed to the first state (100a) by a user, the position of the key button (139) positioned on the side of the third housing part (130) may not be moved. For example, referring to FIG. 1a, in the first state (100a), when the flexible display (140) is viewed from above, the key button (139) may be positioned on the right side. Referring to FIG. 1b, in the third state (100c), when viewing the display (170) from above, the key button (139) can be positioned on the right.

[0038] A flexible display (140) can define the appearance of a foldable electronic device (100) at least partially. The flexible display (140) can be partially disposed within a housing structure (101). The flexible display (140) can define the front of the foldable electronic device (100). The flexible display (140) may include a first unbendable portion (141), a second unbendable portion (142), a third unbendable portion (143), a first bendable portion (144), and a second bendable portion (145). The first unbendable portion (141), the second unbendable portion (142), and the third unbendable portion (143) are contained within the foldable electronic device (100) so as not to be bent, but the first unbendable portion (141), the second unbendable portion (142), and the third unbendable portion (143) detached from the foldable electronic device (100) may be deformable or bendable, such as the first bendable portion (144) and the second bendable portion (145). The first unbendable portion (141) of the flexible display (140) may be placed on the front of the first housing part (110). The second unbendable portion (142) of the flexible display (140) may be placed on the front of the second housing part (120). A third unbendable portion (143) of the flexible display (140) may be placed on the front of the third housing part (130). A first bendable portion (144) of the flexible display (140) may be placed between the first unbendable portion (141) and the third unbendable portion (143) of the flexible display (140). For example, the first bendable portion (144) of the flexible display (140) may be placed on a first hinge structure (150) connecting the first housing part (110) and the second housing part (120).The second bendable portion (145) of the flexible display (140) may be positioned between the second unbendable portion (142) and the third unbendable portion (143) of the flexible display (140). For example, the second bendable portion (145) of the flexible display (140) may be positioned on a second hinge structure (160) connecting the second housing part (120) and the third housing part (130).

[0039] The first hinge structure (150) and the second hinge structure (160) may have the first unbendable portion (141) of the flexible display (140), the second unbendable portion (142) of the flexible display (140), and the third unbendable portion (143) of the flexible display (140) oriented substantially in the same direction. In the first state (100a), the first bendable portion (144) and the second bendable portion (145) may be positioned in substantially the same horizontal plane as the first unbendable portion (141), the second unbendable portion (142), and the third unbendable portion (143).

[0040] The first hinge structure (150) and the second hinge structure (160) can provide a second state (100b) of the foldable electronic device (100). In the second state (100b), the first unbendable portion (141) of the flexible display (140) may face the second unbendable portion (142) of the flexible display (140), and the third unbendable portion (143) of the flexible display (140) may face the same direction as the second unbendable portion (142) of the flexible display (140). For example, the second unbendable portion (142) and the third unbendable portion (143) may be positioned substantially on the same horizontal plane.

[0041] In the second state (100b), the first bendable portion (144) of the flexible display (140) is bent by the first hinge structure (150), so that the first bendable portion (144) of the flexible display (140) can be folded such that the first unbendable portion (141) of the flexible display (140) and the second unbendable portion (142) of the flexible display (140) face in different directions.

[0042] In the second state (100b), the second bendable portion (145) of the flexible display (140) is maintained in an unfolded state by the second hinge structure (160), so that the second bendable portion (145) of the flexible display (140) can be unfolded such that the second unbendable portion (142) of the flexible display (140) and the third unbendable portion (143) of the flexible display (140) face each other in the same direction.

[0043] The first hinge structure (150) and the second hinge structure (160) can provide a third state (100c) of the foldable electronic device (100). In the third state (100c), the second unbendable portion (142) of the flexible display (140) faces the first unbendable portion (141) of the flexible display (140), and the third unbendable portion (143) of the flexible display (140) may face the rear of the first housing part (110).

[0044] In the third state (100c), the first bendable portion (144) of the flexible display (140) is bent by the first hinge structure (150), so that the first bendable portion (144) of the flexible display (140) can be folded such that the first unbendable portion (141) of the flexible display (140) and the second unbendable portion (142) of the flexible display (140) face in different directions.

[0045] In the third state (100c), the second bendable portion (145) of the flexible display (140) is bent by the second hinge structure (160), so that the second bendable portion (145) of the flexible display (140) can be folded such that the second unbendable portion (142) of the flexible display (140) and the third unbendable portion (143) of the flexible display (140) face in different directions. The second bendable portion (145) may further include a first deformation portion (145a), a second deformation portion (145b), and a flat portion (145c). The first deformation portion (145a) may be positioned between the flat portion (145c) and the second unbendable portion (142), and the second deformation portion (145b) may be positioned between the flat portion (145c) and the third unbendable portion (143). The flat portion (145c) may be positioned between the first deformation portion (145a) and the second deformation portion (145b). The flat portion (145c) may be supported by a support plate (e.g., the support plate (264) of FIG. 2a) that is distinct from the hinge plates of the second hinge structure (160) (e.g., the third hinge plate (262) and the fourth hinge plate (263) of FIG. 2a). Regardless of the state of the foldable electronic device (100), the flat portion (145c) may remain flat. The first deformation part (145a) and the second deformation part (145b) are unfolded in the first state (100a) and the second state (100b), and in the third state (100c), the first deformation part (145a) and the second deformation part (145b) can be bent so that the second unbendable part (142) and the third unbendable part (143) face in different directions. In the third state (100c), the first housing part (110) can be positioned between the second housing part (120) and the third housing part (130). In the third state (100c), the second bendable part (145) of the flexible display (140) positioned on the second hinge structure (160) can be partially facing the side (110c) of the first housing part (110).

[0046] The display area of ​​the flexible display (140) may include a first display area (140a), a second display area (140b), and a third display area (140c). The display area represents an area capable of providing visual information from the flexible display (140). In a first state (100a), the entire display area of ​​the flexible display (140) may be visible from the front of the housing structure (101). For example, in a first state (100a), the first display area (140a), the second display area (140b), and the third display area (140c) of the flexible display (140) may be visually exposed. The foldable electronic device (100) may provide a large display area to the user that includes the first display area (140a), the second display area (140b), and the third display area (140c).

[0047] In the second state (100b), the display area of ​​the flexible display (140) may be partially visible from the front of the third housing part (130). For example, the third display area (140c) may be visually exposed, while the first display area (140a) and the second display area (140b) may not be visually exposed.

[0048] In the third state (100c), the display area of ​​the flexible display (140) may not be visible. For example, in the third state (100c), the first display area (140a), the second display area (140b), and the third display area (140c) of the flexible display (140) may not be visually exposed.

[0049] In a non-limiting example, when the flexible display (140) is used to display a screen within a first state (100a) of the foldable electronic device (100), the first display area (140a), the second display area (140b), and the third display area (140c) of the flexible display (140) may be activated. In a non-limiting example, within a third state (100c), the first display area (140a), the second display area (140b), and the third display area (140c) of the flexible display (140) may be deactivated. In a non-limiting example, within a second state (100b) of the foldable electronic device (100), when the flexible display (140) is used to display a screen, the third display area (140c) is activated, and the first display area (140a) and the second display area (140b) of the flexible display (140) may be deactivated.

[0050] In a non-limiting example, when the flexible display (140) is used to display a screen within a first state (100a) of the foldable electronic device (100), the first display area (140a), the second display area (140b), and the third display area (140c) of the flexible display (140) may display visual information. In a non-limiting example, within a third state (100c), the first display area (140a), the second display area (140b), and the third display area (140c) of the flexible display (140) may provide a black image. In a non-limiting example, within a second state (100b) of the foldable electronic device (100), when the flexible display (140) is used to display a screen, the third display area (140c) provides visual information, and the first display area (140a) and the second display area (140b) of the flexible display (140) may provide a black image.

[0052] Referring to FIGS. 2a and 2b, the foldable electronic device (100) may include a first hinge structure (150) and a second hinge structure (160). The first width (w1) of the first hinge structure (150) may be narrower than the second width (w2) of the second hinge structure (160). The difference between the first width (w1) of the first hinge structure (150) and the second width (w2) of the second hinge structure (160) may be equal to or greater than the thickness of the first housing part (110). For example, the second hinge structure (160) may have a second width (w2) that is wider than the first width (w1) so that, according to a third state (100c), the first housing part (110) is positioned between the second housing part (120) and the third housing part (130). The first hinge structure (150) may be referred to as a narrow hinge structure in that it has a narrower width than the second hinge structure (160). The second hinge structure (160) may be referred to as a wide hinge structure in that it has a wider width than the first hinge structure (150).

[0053] The first hinge structure (150) may include a first set of gears (251), a first hinge plate (252), and a second hinge plate (253).

The second hinge plate (254) may be coupled to a second support portion (121) of the second housing part (120). The gears (g11, g12, g13, g14) included in the first set of gears (251) may be configured to rotate the first hinge plate (252) and the second hinge plate (253). For example, the gears (g11, g12, g13, g14) included in the first set of gears (251) can rotate the second hinge plate (253) (or the second housing part (120)) in conjunction with the rotation of the first hinge plate (252) (or the first housing part (110)). After the first hinge plate (252) (or the first housing part (110)) is rotated, the gears (g11, g12, g13, g14) included in the first set of gears (251) can be rotated according to the rotation of the first hinge plate (252) (or the first housing part (110)). The second hinge plate (253) (or the second housing part (120)) may be rotated in conjunction with the rotation of the first hinge plate (252) according to the rotation of the gears included in the first set of gears (251).

Depending on the first rotational direction (e.g., clockwise) of the first gear (g11), the second gear (g12) engaged with the first gear (g11) can be rotated in a second rotational direction (e.g., counterclockwise) opposite to the first rotational direction. Depending on the second rotational direction of the second gear (g2), the third gear (g13) engaged with the second gear (g12) can be rotated in the first rotational direction. Depending on the first rotational direction of the third gear (g13), the fourth gear (g14) can be rotated in the second rotational direction.

The fourth hinge plate (263) may be coupled to the third support portion (131) of the third housing part (130). The gears (g21, g22, g23, g24, g25, g26) included in the second set of gears (261) may be configured to rotate the third hinge plate (262) and the fourth hinge plate (263). For example, the gears (g21, g22, g23, g24, g25, g26) included in the second set of gears (261) can rotate the fourth hinge plate (263) (or the third housing part (130)) in conjunction with the rotation of the third hinge plate (262) (or the second housing part (120)). After the third hinge plate (262) (or the second housing part (120)) is rotated, the gears (g21, g22, g23, g24, g25, g26) included in the second set of gears (261) can be rotated according to the rotation of the third hinge plate (262) (or the second housing part (120)). The fourth hinge plate (263) (or the third housing part (130)) can be rotated in conjunction with the rotation of the third hinge plate (262) according to the rotation of the gears (g21, g22, g23, g24, g25, g26) included in the second set (261) of gears.

[0055] The gears (g21, g22, g23, g24, g25, g26) included in the second set (261) of gears may include a first gear (g21), a second gear (g22), a third gear (g23), a fourth gear (g24), a fifth gear (g25), and a sixth gear (g26). The first gear (g21) may be positioned adjacent to the third hinge plate (262), and the sixth gear (g26) may be positioned adjacent to the fourth hinge plate (263). The second gear (g22), the third gear (g23), the fourth gear (g24), and the fifth gear (g25) may be positioned between the first gear (g21) and the sixth gear (g26). The first gear (g21), second gear (g22), third gear (g23), fourth gear (g24), fifth gear (g25), and sixth gear (g26) can be engaged sequentially. Depending on the first rotational direction (e.g., clockwise) of the first gear (g21), the second gear (g22) engaged with the first gear (g21) can be rotated in a second rotational direction (e.g., counterclockwise) opposite to the first rotational direction. Depending on the second rotational direction of the second gear (g22), the third gear (g23) engaged with the second gear (g22) can be rotated in the first rotational direction. Depending on the first rotational direction of the third gear (g23), the fourth gear (g24) can be rotated in the second rotational direction. Depending on the rotation of the fourth gear (g24) in the second rotational direction, the fifth gear (g25) engaged with the fourth gear (g24) can be rotated in the first rotational direction. Depending on the rotation of the fifth gear (g25) in the first rotational direction, the sixth gear (g26) engaged with the fifth gear (g25) can be rotated in the second rotational direction. As the first gear (g21) and the sixth gear (g26) rotate in different directions, the second housing part (120) connected to the third hinge plate (262) and the third housing part (130) connected to the fourth hinge plate (263) can be folded or unfolded.

[0059] Hardware components placed on the first printed circuit board (271) may support or operate independently of hardware components placed on the second printed circuit board (272) and / or hardware components placed on the third printed circuit board (273).

[0060] Hardware components placed on the second printed circuit board (272) may support or operate independently of hardware components placed on the first printed circuit board (271) or the third printed circuit board (273).

The sub-printed circuit board (275) may be disposed in at least a portion of the first housing part (110), the second housing part (120), and the third housing part (130). The flexible printed circuit boards (280, 290) may include a first flexible printed circuit board (280) and a second flexible printed circuit board (290). The first flexible printed circuit board (280) may electrically connect the printed circuit board disposed in each of the housing parts (110, 120, 130). The second flexible printed circuit board (290) may connect the printed circuit board in the housing part where the sub-printed circuit board (275) is disposed with the sub-printed circuit board (275) by means of the second flexible printed circuit board (290).

[0063] Components within the foldable electronic device (100) may be connected to at least one processor within a third printed circuit board (273) via flexible printed circuit boards (280, 290). For example, a signal received from an antenna placed in the third housing part (130) may be transmitted to the third printed circuit board (273) where at least one processor (e.g., AP or CP) is placed via a signal path (a) provided by the first flexible printed circuit board (280).

[0064] The foldable electronic device (100) may further include batteries. Each of the batteries may be attached to support portions (111, 121, 131) included in the housing parts (110, 120, 130). The support portions (111, 121, 131) may support rechargeable batteries.

[0065] The arrangement of hardware components is exemplary, and unlike the above, the rear camera (175) and the second printed circuit board (272) may be placed in the third housing part (130), and the third printed circuit board (273) may be placed in the second housing part (120).

[0066] The first housing part (110) and the third housing part (130) are shown to rotate in opposite directions relative to the second housing part (120), but are not limited thereto. For example, while changing from the first state (100a) to the third state (100c), the first housing part (110) may rotate counterclockwise relative to the second housing part (120), and the third housing part (130) may rotate counterclockwise relative to the second housing part (120). As the first housing part (110) and the third housing part (130) rotate in the same direction, a portion of the display area of ​​the flexible display (140) in the second state may be visually exposed.

[0067] A housing structure (101) (which may be described as housing (101)) of a foldable electronic device (100) may include a first housing part (110), a second housing part (120) rotatably coupled to the first housing part (110), and a third housing part (130) rotatably coupled to the second housing part (120). Since the second housing part (120) is rotatably coupled to both the first housing part (110) and the third housing part (130), the second housing part (120) may be partially folded to both the first housing part (110) and the third housing part (130). The foldable electronic device (100) may be configured to have a triangular prism shape in accordance with a second housing part (120) that is partially folded with respect to both the first housing part (110) and the third housing part (130). The foldable electronic device (100) having the triangular prism shape is described with reference to FIG. 3a.

[0068] FIG. 3a illustrates a foldable electronic device having a triangular prism shape.

[0069] Referring to FIG. 3a, the second housing part (120) may be partially folded with respect to the first housing part (110) and partially folded with respect to the third housing part (130). The third housing part (130) may be supported by the first housing part (110) according to the second housing part (120) which is partially folded with respect to both the first housing part (110) and the third housing part (130). A portion of the third housing part (130) may be positioned on the first housing part (110) according to the second housing part (120) which is partially folded with respect to the first housing part (110) and the third housing part (130). A foldable electronic device (100) may be configured to have a triangular prism shape (or a rounded triangular prism shape) as illustrated in FIG. 3a when a third housing part (130) is supported by a first housing part (110) according to a second housing part (120) that is partially folded with respect to the first housing part (130). A foldable electronic device (100) may be configured to have the triangular prism shape when a part of the third housing part (130) is positioned on (or contacted with) the first housing part (110). A foldable electronic device (100) may be configured to have the triangular prism shape when the third housing part (130) is supported by the first housing part (110). The foldable electronic device (100) may be configured to have the triangular prism shape when the third housing part (130) is supported by the first housing part (110). When the foldable electronic device (100) has the triangular prism shape, the foldable electronic device (100) can provide various user experiences (UX).A foldable electronic device (100) having a triangular prism shape can provide various user experiences through a display (e.g., the flexible display (140) of FIG. 1a) forming the inner sides of the triangular prism.

[0070] The foldable electronic device (100) may include a speaker (315). Although the speaker (315) is shown in FIG. 3a as being contained within a second housing part (120), this is exemplary, and the speaker (315) may be contained within a first housing part (110), a second housing part (120), and / or a third housing part (130). For example, the speaker (315) may be configured to output an audio signal through a side wall of the second housing part (120) perpendicular to the folding axis of the foldable electronic device (100). The foldable electronic device (100) having a triangular prism shape may provide various user experiences through the speaker (315). While the foldable electronic device (100) has a triangular prism shape, it may output an audio signal (320) through the speaker (315).

[0071] When the foldable electronic device (100) has a triangular prism shape, a space surrounded by the foldable electronic device (100) may be formed (or caused). For example, destructive interference of the audio signal (320) may occur (or be caused) by the space surrounded by the foldable electronic device (100). Destructive interference of the audio signal (320) caused by the space surrounded by the foldable electronic device (100) is exemplified in the description of FIG. 3b.

[0072] FIG. 3b is a cross-sectional view illustrating an example of a foldable electronic device having a triangular prism shape cut along A-A' of FIG. 3a.

[0073] Referring to FIG. 3b, the foldable electronic device (100) can output an audio signal (320) through a speaker (315). The audio signal (320) output through the speaker (315) can be spread or radiated in all directions. For example, the audio signal (320) may include a first audio signal (320-1) radiated to the outside of the space enclosed by the foldable electronic device (100) having a triangular prism shape and a second audio signal (320-2) radiated into the space.

[0074] For example, a second audio signal (320-2) radiated into the space may be reflected by colliding with the side wall (330) of the third housing part (130) in contact with the first housing part (110). For example, the reflected second audio signal (320-2) may pass through the space. For example, as the second audio signal (320-2) passes through the space, a phase difference between the first audio signal (320-1) and the second audio signal (320-2) may occur (or be caused). For example, after passing through the space, the second audio signal (320-2) may be superimposed on the first audio signal (320-1) in an area (or zone, or space, or point) (325) outside the space. As the first audio signal (320-1) and the second audio signal (320-2) having a phase difference overlap in region (325), destructive interference between the first audio signal (320-1) and the second audio signal (320-2) may occur (or be caused).

[0075] The sound pressure of the audio signal (320) in the reference frequency range may be reduced due to destructive interference between the first audio signal (320-1) and the second audio signal (320-2). As the sound pressure of the audio signal (320) in the reference frequency range is reduced, the audio signal (320) may sound relatively quiet to the user, or the sound quality of the audio signal (320) may deteriorate. As the sound quality of the audio signal (320) deteriorates or the audio signal (320) sounds relatively quiet, the user may experience discomfort. A method may be required to resolve the user's discomfort caused by the reduction in the sound pressure of the audio signal (320) in the reference frequency range.

[0076] To resolve this inconvenience, the foldable electronic device (100) can tune an audio signal (320) on a reference frequency range. For example, the foldable electronic device (100) can identify a reference frequency range in which the sound pressure of the audio signal (320) is reduced based on detecting an event in which the audio signal (320) is output while the foldable electronic device (100) has a triangular prism shape. For example, the foldable electronic device (100) can tune an audio signal (320) on a reference frequency range based on identifying the reference frequency range. The foldable electronic device (100) can perform operations exemplified in the description of FIGS. 5 to 10b to tune the audio signal (320). The foldable electronic device (100) may include components for performing said operations. said components may be exemplified in the description of FIG. 4.

[0077] Figure 4 is a simplified block diagram of an exemplary foldable electronic device.

[0079] A speaker (315) may be used to output an audio signal. For example, the speaker (315) may be included in a first housing part (110), a second housing part (120), and / or a third housing part (130). For example, the speaker (315) may be configured to output an audio signal through a side wall of the second housing part (120) (or the first housing part (110), or the third housing part (130)) that is perpendicular to the folding axis of the foldable electronic device (100).

[0080] At least one processor (410) may include a processing circuit. For example, at least one processor (410) may include a central processing unit (e.g., including a processing circuit). For example, at least one processor (410) may include a graphic processing unit (e.g., including a processing circuit) and / or a neural processing unit (e.g., including a processing circuit). For example, at least one processor (410) may be described as an application processor. For example, at least one processor (410) may be configured to control a speaker (315), a memory (420), at least one sensor (440), and at least one other sensor (450). At least one processor (410) may be configured to execute instructions stored in memory (420) individually or collectively to cause the foldable electronic device (100) to perform at least some of the operations illustrated in the description of FIGS. 3a and 3b. At least one processor (410) may be configured to execute instructions stored in memory (420) to cause the foldable electronic device (100) to perform at least some of the operations illustrated in the description of FIGS. 5 to 10b.

[0081] For example, the term “processor” as used herein, including in the claims, may include various processing circuits comprising at least one processor, and one or more of said at least one processor may be configured to perform the various functions described below in a distributed manner, individually and / or collectively. As used below, where “processor,” “at least one processor,” and “one or more processors” are described as being configured to perform various functions, these terms encompass, for example, but not limited to, situations where one processor performs some of the cited functions and another processor(s) perform other parts of the cited functions, and also situations where one processor can perform all of the cited functions. Additionally, said at least one processor may include a combination of processors that perform the enumerated / disclosed various functions, for example, in a distributed manner. At least one processor may execute program instructions to achieve or perform the various functions.

[0082] The memory (420) may include one or more storage media. For example, the memory (420) may store various data used by at least one component of the foldable electronic device (100) (e.g., speaker (315), at least one processor (410), at least one sensor (440), and / or at least one other sensor (450)). For example, the data may include input data or output data for software and related commands. The memory (420) may include volatile memory or non-volatile memory.

For example, at least one sensor (440) may be placed in each of the first housing part (110), the second housing part (120), and the third housing part (130). For example, at least one sensor (440) may generate or output data representing the translational motion of the foldable electronic device (100) measured in each of the three axes (e.g., x-axis, y-axis, and z-axis) and / or the rotational motion of the foldable electronic device (100) measured in each of the rotational directions of each of the three axes (e.g., roll direction, pitch direction, and yaw direction), such as an inertial measurement unit (IMU).

Data representing rotational motion may include angular velocities for each of the rotation directions. To measure angular velocity, at least one sensor (440) may include a gyroscope. At least one sensor (440) may include a Hall sensor. For example, at least one sensor (440) may be configured to identify (or measure) an angle between the first housing part (110) and the second housing part (120). For example, at least one sensor (440) may be configured to identify (or measure) another angle between the second housing part (120) and the third housing part (130).For example, at least one sensor (440) may be configured to identify whether the first housing part and the second housing part are folded, or whether the first housing part and the second housing part are unfolded, or whether the first housing part and the second housing part are partially folded. For example, at least one sensor (440) may be configured to identify whether the second housing part and the third housing part are folded, or whether the second housing part and the third housing part are unfolded, or whether the second housing part and the third housing part are partially folded.

[0084] At least one other sensor (450) may include a circuit for generating and / or outputting electrical information (e.g., sensor data) that can be processed by at least one processor (210) from non-electrical information (or can be stored in memory (420)).

However, it is not limited thereto.

[0085] The foldable electronic device (100) illustrated in the description of FIG. 4 can perform at least some of the operations illustrated in the descriptions of FIG. 5 through 10b. For example, the operations illustrated in the descriptions of FIG. 5 through 10b can be caused by (or in) the foldable electronic device (100) under the control of at least one processor (410).

[0086] FIG. 5 is a flowchart illustrating exemplary operations of a foldable electronic device for identifying whether the foldable electronic device has a triangular prism shape.

[0087] Referring to FIG. 5, in operation 500, at least one processor (410) can identify an angle between the first housing part (110) and the second housing part (120) through at least one sensor (440). At least one processor (410) can identify another angle between the second housing part (120) and the third housing part (130) through at least one sensor (440).

[0088] As another example, at least one processor (410) can identify an angle between the first housing part (110) and the second housing part (120) based on the degree of rotation of the gears of the foldable electronic device (100) (e.g., the gears (g11, g12, g13, g14) of FIG. 2a). At least one processor (410) can identify another angle between the second housing part (120) and the third housing part (130) based on the degree of rotation of the gears of the foldable electronic device (100) (e.g., the gears (g21, g22, g23, g24, g25, g26) of FIG. 2a). However, it is not limited thereto.

[0089] In operation 510, at least one processor (410) can identify that the foldable electronic device (100) has a triangular prism shape based on an angle between the first housing part (110) and the second housing part (120) and another angle between the second housing part (120) and the third housing part (130). Identifying that the foldable electronic device (100) has a triangular prism shape based on said angle and said other angle is illustrated with reference to FIG. 3a.

[0090] Referring again to FIG. 3a, when the first housing part (110) and the second housing part (120) are partially bent, and when the second housing part (120) and the third housing part (120) are partially bent, the foldable electronic device (100) may have a triangular prism shape. When the second housing part (120) is partially bent with respect to both the first housing part (110) and the third housing part (130), the foldable electronic device (100) may have a triangular prism shape.

[0091] At least one processor (410) can identify that the first housing part (110) and the second housing part (120) are partially bent based on an angle (300) between the first housing part (110) and the second housing part (120). At least one processor (410) can identify that the second housing part (120) and the third housing part (130) are partially bent based on another angle (305) between the second housing part (120) and the third housing part (130). At least one processor (410) can identify that the foldable electronic device (100) has a triangular prism shape based on the angle (300) and another angle (305).

[0092] For example, at least one processor (410) can identify whether an angle (300) is within a first angle range and another angle (305) is within a second angle range. For example, at least one processor (410) can identify that the foldable electronic device (100) has a triangular prism shape based on identifying that the angle (300) is within a first angle range and another angle (305) is within a second angle range. For example, the first angle range may be defined as an angle range in which the distance between the first housing part (110) and the hinge structure (e.g., the second hinge structure (160) of FIG. 1a) connecting the second housing part (120) and the third housing part (130) is greater than or equal to a reference distance. For example, the first angle range may be defined as an angle range of 120 degrees or less. For example, the second angle range may be described as an angle range between 0 degrees and 90 degrees (e.g., an acute angle).

[0093] When the foldable electronic device (100) has a triangular prism shape, the side wall of the first housing part (110) parallel to the folding axis of the foldable electronic device (100) and the third housing part (130) may be relatively close. For example, when the foldable electronic device (100) has a triangular prism shape, the distance between the side wall of the first housing part (110) and the third housing part (130) may be relatively short. At least one processor (410) can identify the distance between the side wall of the first housing part (110) and the third housing part (130) based on an angle (300) and another angle (305). At least one processor (410) can identify whether the foldable electronic device (100) has a triangular prism shape based on the distance between the side wall of the first housing part (110) and the third housing part (130). The distance between the side wall of the first housing part (110) and the third housing part (130) is exemplified in the description of FIG. 6.

[0094] Figure 6 is a cross-sectional view of a foldable electronic device having a triangular prism shape.

[0095] Referring to FIG. 6, a first housing part (110) of a foldable electronic device (100) may include a side wall (600). The side wall (600) of the first housing part (110) may have a width (h1). At least one processor (410) may identify an angle (300) between the first housing part (110) and the second housing part (120) and another angle (305) between the second housing part (120) and the third housing part (130) through at least one sensor (440). For example, at least one processor (410) may identify the folded state of the foldable electronic device (100) based on the angle (300) and the other angle (305). For example, the distance (h2) between the side wall (600) of the first housing part (110) and the third housing part (130) may vary depending on the folded state of the foldable electronic device (100). For example, the distance (h2) between the side wall (600) of the first housing part (110) and the third housing part (130) may be described as the distance between the side wall (600) of the first housing part (110) and the front (605) of the third housing part (130). For example, since the distance (h2) varies depending on the folded state of the foldable electronic device (100), the distance (h2) may be shorter or longer than the width (h1) of the side wall (600) of the first housing part (110).

[0096] At least one processor (410) can identify a folded state of a foldable electronic device (100) in which the distance (h2) between the side wall (600) of the first housing part (110) and the third housing part (130) is shorter than the width (h1) of the side wall (600) of the first housing part (110). For example, a folded state of a foldable electronic device (100) in which the distance (h2) between the side wall (600) of the first housing part (110) and the third housing part (130) is shorter than the width (h1) of the side wall (600) of the first housing part (110) can be defined as a folded state of a foldable electronic device (100) in which the foldable electronic device (100) has a triangular prism shape. At least one processor (410) can identify a folded state of a foldable electronic device (100) in which the distance (h2) between the side wall (600) of the first housing part (110) and the third housing part (130) is longer than the width (h1) of the side wall (600) of the first housing part (110). For example, a folded state of a foldable electronic device (100) in which the distance (h2) between the side wall (600) of the first housing part (110) and the third housing part (130) is longer than the width (h1) of the side wall (600) of the first housing part (110) can be defined as a folded state of a foldable electronic device (100) in which the foldable electronic device (100) does not have a triangular prism shape. However, it is not limited thereto.

[0097] Referring again to FIG. 5, in operation 520, at least one processor (410) can detect an event for outputting an audio signal while identifying that the foldable electronic device (100) has a triangular prism shape. For example, the event for outputting an audio signal may include the playback of media content, the reception of a notification, a virtual keyboard, and / or the reception of a phone call (or message, or mail). However, it is not limited thereto.

[0098] For example, the audio signal to be output through the speaker (315) may be subject to (or caused to be subjected to) destructive interference by the foldable electronic device (100) having a triangular prism shape. For example, the sound pressure of the audio signal may be reduced within a reference frequency range due to the destructive interference. To increase the sound pressure of the audio signal reduced within the reference frequency range, it may be required to tune the audio signal within the reference frequency range.

[0099] At least one processor (410) may output an untuned audio signal through a speaker (315) based on the event detected while identifying the folded state of a foldable electronic device (100) that does not have a triangular prism shape. For example, at least one processor (410) may output another audio signal through a speaker (315) based on the event detected while identifying the folded state of a foldable electronic device (100) that does not have a triangular prism shape, to guide the folded state of the foldable electronic device (100) to change to the folded state of a foldable electronic device (100) that has a triangular prism shape. In another example, at least one processor (410) may display information guiding the change of the folded state of the foldable electronic device (100) to the folded state of the foldable electronic device (100) having a triangular prism shape through a display placed on the rear of the second housing part, based on the event detected while identifying the folded state of the foldable electronic device (100) not having a triangular prism shape. In yet another example, at least one processor (410) may display information guiding the change of the folded state of the foldable electronic device (100) to the folded state of the foldable electronic device (100) having a triangular prism shape through a flexible display placed across the front of the first housing part, the front of the second housing part, and the front of the third housing part, based on the event detected while identifying the folded state of the foldable electronic device (100) not having a triangular prism shape.

[0100] At least one processor (410) may identify a reference frequency range to tune an audio signal within a reference frequency range based on the event detected while identifying the folded state of the foldable electronic device (100) having a triangular prism shape. For example, the reference frequency range in which the sound pressure of the audio signal is reduced may vary depending on the pose or posture (or orientation) of the foldable electronic device (100) having a triangular prism shape. Identifying the pose of the foldable electronic device (100) having a triangular prism shape to identify the reference frequency range is exemplified in the description of FIG. 7.

[0101] FIG. 7 is a flowchart illustrating exemplary operations of a foldable electronic device for identifying the posture of the foldable electronic device.

[0102] Referring to FIG. 7, in operation 700, at least one processor (410) can detect an event for outputting an audio signal while identifying that the foldable electronic device (100) has a triangular prism shape. For example, operation 700 may correspond to operation 520 of FIG. 5.

[0103] In operation 710, at least one processor (410) can identify the posture (or orientation) of a foldable electronic device (100) having a triangular prism shape through at least one other sensor (450). As an example without limitation, at least one processor (410) can identify the posture (or orientation) of a foldable electronic device (100) having a triangular prism shape by identifying the direction of the foldable electronic device (100) through at least one other sensor (450). At least one processor (410) can identify the posture (or orientation) of a foldable electronic device (100) having a triangular prism shape by identifying the tilt of the foldable electronic device (100) through at least one other sensor (450). At least one processor (410) can identify the posture (or orientation) of a foldable electronic device (100) having a triangular prism shape through at least one other sensor (450), depending on whether the foldable electronic device (100) comes into contact with an external object (e.g., a floor). However, it is not limited thereto.

[0104] As another example, the foldable electronic device (100) may further include another speaker (e.g., another speaker (800) of FIG. 8a). The other speaker may be included in a first housing part (110), a second housing part (120), and / or a third housing part (130). For example, the other speaker may be configured to output an audio signal through an edge opposite to the edge where the speaker (315) of the foldable electronic device (100) is positioned, and which is perpendicular to the folding axis of the foldable electronic device (100). At least one processor (410) may identify whether the other speaker is clogged. By identifying whether the other speaker is clogged, the at least one processor (410) may identify the orientation of the foldable electronic device (100) having a triangular prism shape.

[0105] In operation 720, at least one processor (410) can identify a first reference frequency range based on identifying that the foldable electronic device (100) having a triangular prism shape has a first orientation through at least one other sensor (450) (or other speaker). The first reference frequency range may correspond to the length of the edge of the first housing part (110) or the third housing part (130) perpendicular to the folding axis of the foldable electronic device (100). The first orientation of the foldable electronic device (100) having a triangular prism shape is described with reference to FIG. 3a. The first reference frequency range is described with reference to FIG. 3b.

[0106] Referring again to FIG. 3a, a foldable electronic device (100) having a triangular prism shape may have a first posture. For example, when the foldable electronic device (100) having a triangular prism shape has a first posture, the rear wall of the first housing part (110) may be supported by an external object (e.g., floor). In FIG. 3a, a foldable electronic device (100) in which the rear wall of the first housing part (110) is supported by an external object is shown, but this is exemplary, and when the foldable electronic device (100) having a triangular prism shape has a first posture, the rear wall of the second housing part (120) may be supported by an external object (e.g., floor), or the rear wall of the third housing part (130) may be supported by an external object (e.g., floor).

[0107] When the foldable electronic device (100) having a triangular prism shape has a first posture, the side walls of the first housing part (110), the side walls of the second housing part (120), and the side walls of the third housing part (130) may not be supported by an external object (e.g., a floor). Because the side walls of the first housing part (110), the side walls of the second housing part (120), and the side walls of the third housing part (130) are not supported by an external object (e.g., a floor) when the foldable electronic device (100) having a triangular prism shape has a first posture, other speakers configured to output an audio signal through the edge of the foldable electronic device (100) perpendicular to the folding axis of the foldable electronic device (100) may not be blocked. At least one processor (410) can identify that the foldable electronic device (100) having a triangular prism shape has a first posture based on identifying that other speakers are not blocked.

[0108] When the foldable electronic device (100) has a triangular prism shape, a space surrounded by the foldable electronic device (100) may be formed (or caused). When the foldable electronic device (100) having a triangular prism shape has a first posture, both sides of the space surrounded by the foldable electronic device (100) may be open. While the foldable electronic device (100) having a triangular prism shape has the first posture, when at least one processor (410) outputs an audio signal (320) through a speaker (315), at least a portion of the audio signal (320) may be radiated toward the space surrounded by the foldable electronic device (100) with both sides open.

[0109] Referring again to FIG. 3b, the second audio signal (320-2) can be radiated toward a space enclosed by a foldable electronic device (100) with both sides open. For example, the second audio signal (320-2) can be moved in a first direction by the length (L) of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100) until it passes through the space enclosed by the foldable electronic device (100).

[0110] For example, at least a portion of the second audio signal (320-2) radiated into the space may collide with the side wall (330) of the third housing part (130) in contact with the first housing part (110). At least a portion of the second audio signal (320-2) may be moved in a second direction perpendicular to the first direction by a distance (a) between the side wall (330) of the third housing part (130) in contact with the first housing part (110) and the second housing part (120). For example, at least a portion of the second audio signal (320-2) may be reflected by colliding with the side wall (330) of the third housing part (130) in contact with the first housing part (110). For example, the reflected second audio signal (320-2) can be moved in a third direction opposite to the second direction by the distance (a) between the side wall of the third housing part (130) in contact with the first housing part (110) and the second housing part (120) until it passes through the space surrounded by the foldable electronic device (100).

[0111] For example, as the second audio signal (320-2) passes through the space, a phase difference between the first audio signal (320-1) and the second audio signal (320-2) may occur (or be caused). The phase difference between the first audio signal (320-1) and the second audio signal (320-2) may correspond to the distance of the second audio signal (320-2) moved to pass through the space. For example, the first reference frequency range in which the phase difference between the first audio signal (320-1) and the second audio signal (320-2) occurs may correspond to the length (L) of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100) and the distance (a) between the side wall of the third housing part (130) in contact with the first housing part (110) and the second housing part (120). For example, the second audio signal (320-2) may be superimposed on the first audio signal (320-1) in an area (or zone, or space, or point) (325) outside the space after passing through the space. As the first audio signal (320-1) and the second audio signal (320-2) having a phase difference are superimposed in the area (325), destructive interference may occur (or be caused) between the first audio signal (320-1) and the second audio signal (320-2) on a first reference frequency range.

[0112] The sound pressure of the audio signal (320) in the first reference frequency range may be reduced by destructive interference between the first audio signal (320-1) and the second audio signal (320-2). As the sound pressure of the audio signal (320) in the first reference frequency range is reduced, the audio signal (320) may be heard relatively quietly by the user, or the sound quality of the audio signal (320) may be degraded.

[0113] A first reference frequency range can be obtained according to the following mathematical formula 1. The first reference frequency range can be obtained by applying the length (L) of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100) and the distance (a) between the side wall of the third housing part (130) in contact with the first housing part (110) and the second housing part (120) to the following mathematical formula 1.

[0114]

[0115] Mathematical Formula 1 is merely an example to aid understanding, and embodiments of the present disclosure are not limited thereto. Mathematical Formula 1 may be modified, applied, or extended in various ways.

[0116] In mathematical formula 1, represents a frequency within a first reference frequency range, c represents the speed of light, L represents the length of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100), and a represents the distance between the side wall (330) of the third housing part (130) in contact with the first housing part (110) and the second housing part (120). The upper limit of the first reference frequency range is and the lower limit of the first reference frequency range is It could be.

[0117] Referring again to FIG. 7, in operation 730, at least one processor (410) can tune an audio signal over a first reference frequency range. For example, a peak filter, a dynamic range compressor (DRC), a notch filter, a high pass filter, a low pass filter, and / or a band pass filter may be used to tune the audio signal. However, it is not limited thereto. For example, tuning the audio signal may include compensating (or amplifying) the sound pressure of the audio signal. At least one processor (410) can tune the audio signal over the first reference frequency range by compensating (or amplifying) the sound pressure of the audio signal over the first reference frequency range.

[0118] At least one processor (410) can increase the sound pressure of an audio signal in a first reference frequency range that has been reduced by destructive interference by tuning the audio signal in a first reference frequency range. By increasing the sound pressure of the audio signal in the first reference frequency range, the audio signal in the first reference frequency range may be heard relatively louder by the user, or the sound quality of the audio signal in the first reference frequency range may be enhanced (or improved). At least one processor (410) can enhance the user experience provided through a foldable electronic device (100) having a triangular prism shape by increasing the sound pressure of the audio signal in the first reference frequency range.

[0119] In operation 740, at least one processor (410) may identify a second reference frequency range based on identifying that the foldable electronic device (100) having a triangular prism shape has a second orientation through at least one other sensor (450) (or other speaker). The second reference frequency range may correspond to the length of the edge of the first housing part (110) or the third housing part (130) perpendicular to the folding axis of the foldable electronic device (100). The second orientation of the foldable electronic device (100) having a triangular prism shape is illustrated in the description of FIG. 8a. The second reference frequency range is illustrated in the description of FIG. 8b.

[0120] FIG. 8a illustrates a foldable electronic device having a second posture.

[0121] FIG. 8b is a cross-sectional view illustrating an example of a foldable electronic device having a second posture cut along B-B' of FIG. 8a.

[0122] Referring to FIG. 8a, a foldable electronic device (100) having a triangular prism shape may have a second position. For example, when the foldable electronic device (100) having a triangular prism shape has a second position, the side wall of the first housing part (110), the side wall of the second housing part (120), and the side wall of the third housing part (130) may be supported by an external object (805) (e.g., a floor). When the foldable electronic device (100) having a triangular prism shape has a second position, the side wall of the first housing part (110), the side wall of the second housing part (120), and the side wall of the third housing part (130) are supported by an external object (805), so another speaker (800) configured to output an audio signal through the edge of the foldable electronic device (100) perpendicular to the folding axis of the foldable electronic device (100) may be blocked. At least one processor (410) can identify that the foldable electronic device (100) having a triangular prism shape has a second posture based on identifying that the other speaker (800) is blocked.

[0123] When the foldable electronic device (100) has a triangular prism shape, a space surrounded by the foldable electronic device (100) may be formed (or caused). When the foldable electronic device (100) having a triangular prism shape has a second posture, a first side of the space surrounded by the foldable electronic device (100) is open, and a second side opposite to the first side of the space surrounded by the foldable electronic device (100) may be blocked by an external object (805). While the foldable electronic device (100) having a triangular prism shape has a second posture, when at least one processor (410) outputs an audio signal (320) through a speaker (315), at least a portion of the audio signal (320) may be radiated toward the space surrounded by the foldable electronic device (100), where the first side is open and the second side is blocked by an external object (805).

[0124] Referring to FIG. 8b, a second audio signal (320-2) may be radiated toward a space enclosed by a foldable electronic device (100) in which a first surface is open and a second surface is blocked by an external object (805). For example, the second audio signal (320-2) may be radiated through the open first surface and collide with the external object (805) blocking the second surface. The second audio signal (320-2) may be moved in a first direction by the length (L) of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100) until it collides with the external object (805) blocking the second surface. For example, the second audio signal (320-2) may be reflected by colliding with the external object (805) blocking the second surface. For example, the reflected second audio signal (320-2) can be moved in a second direction opposite to the first direction by the length (L) of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100) until it passes through the first surface of the space surrounded by the foldable electronic device (100).

[0125] For example, at least a portion of the second audio signal (320-2) radiated into the space may collide with the side wall (330) of the third housing part (130) in contact with the first housing part (110). At least a portion of the second audio signal (320-2) may be moved in a third direction perpendicular to the first direction and the second direction by a distance (a) between the side wall (330) of the third housing part (130) in contact with the first housing part (110) and the second housing part (120). For example, at least a portion of the second audio signal (320-2) may be reflected by colliding with the side wall (330) of the third housing part (130) in contact with the first housing part (110). For example, the reflected second audio signal (320-2) can be moved in a fourth direction opposite to the third direction by the distance (a) between the side wall of the third housing part (130) in contact with the first housing part (110) and the second housing part (120) until it passes through the first surface of the space surrounded by the foldable electronic device (100).

[0126] For example, as the second audio signal (320-2) passes through the first surface of the space, a phase difference between the first audio signal (320-1) and the second audio signal (320-2) may occur (or be caused). The phase difference between the first audio signal (320-1) and the second audio signal (320-2) may correspond to the distance of the second audio signal (320-2) moved to pass through the first surface of the space. For example, the second reference frequency range in which the phase difference between the first audio signal (320-1) and the second audio signal (320-2) occurs may correspond to the length (L) of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100) and the distance (a) between the side wall of the third housing part (130) in contact with the first housing part (110) and the second housing part (120). For example, the second audio signal (320-2) may be superimposed on the first audio signal (320-1) in an area (or zone, or space, or point) (810) outside the space after passing through the first surface of the space. As the first audio signal (320-1) and the second audio signal (320-2) having a phase difference are superimposed in the area (810), destructive interference may occur (or be caused) between the first audio signal (320-1) and the second audio signal (320-2) on a second reference frequency range.

[0127] The sound pressure of the audio signal (320) in the second reference frequency range may be reduced by destructive interference between the first audio signal (320-1) and the second audio signal (320-2). As the sound pressure of the audio signal (320) in the first reference frequency range is reduced, the audio signal (320) may be heard relatively quietly by the user, or the sound quality of the audio signal (320) may be degraded.

[0128] The second reference frequency range can be obtained according to the following mathematical formula 2. The second reference frequency range can be obtained by applying the length (L) of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100) and the distance (a) between the side wall of the third housing part (130) in contact with the first housing part (110) and the second housing part (120) to the following mathematical formula 2.

[0129]

[0130] Mathematical Formula 2 is merely an example to aid understanding, and embodiments of the present disclosure are not limited thereto. Mathematical Formula 2 may be modified, applied, or extended in various ways.

[0131] In mathematical formula 2, indicates a frequency within a second reference frequency range, c indicates the speed of light, L indicates the length of the edge of the first housing part (110) or the third housing part (130) parallel to the folding axis of the foldable electronic device (100), and a may indicate the distance between the side wall (330) of the third housing part (130) in contact with the first housing part (110) and the second housing part (120). The upper limit of the second reference frequency range is It can be, and the lower limit of the second reference frequency range is It could be.

[0132] Referring again to FIG. 7, in operation 750, at least one processor (410) can tune an audio signal on a second reference frequency range. For example, tuning an audio signal on a second reference frequency range may be described by referring to the description of tuning an audio signal on a first reference frequency range in operation 730.

[0133] At least one processor (410) can increase the sound pressure of the audio signal in the second reference frequency range that has been reduced by destructive interference by tuning the audio signal in the second reference frequency range. By increasing the sound pressure of the audio signal in the second reference frequency range, the audio signal in the second reference frequency range may be heard relatively louder by the user, or the sound quality of the audio signal in the second reference frequency range may be enhanced (or improved). At least one processor (410) can enhance the user experience provided through the foldable electronic device (100) having a triangular prism shape by increasing the sound pressure of the audio signal in the second reference frequency range.

[0134] Figure 9 illustrates an example of a chart representing the sound pressure of an audio signal according to frequency.

[0135] Referring to FIG. 9, the chart (900) represents the change in sound pressure of an audio signal according to frequency. The horizontal axis (905) in the chart (900) indicates frequency, and the vertical axis (910) in the chart (900) indicates the sound pressure of the audio signal. The horizontal axis (905) in the chart (900) may have units of Hz (Hertz), and the vertical axis (910) in the chart (900) may have units of dB (decibel).

[0136] The sound pressure of the audio signal output through the speaker (315) while the foldable electronic device (100) having a triangular prism shape is in a first position can be represented as the first line (915) in the chart (900). The sound pressure of the audio signal output through the speaker (315) while the foldable electronic device (100) having a triangular prism shape is in a second position can be represented as the second line (920) in the chart (900).

[0137] For example, a dip in the sound pressure of the audio signal represented by the first line (915) may occur (or be caused) within the first reference frequency range (925). The dip in the sound pressure of the audio signal may occur (or be caused) by destructive interference of the audio signal output through the speaker (315) while the foldable electronic device (100) having a triangular prism shape is in the first position. The sound pressure of the audio signal represented by the first line (915) may decrease rapidly within the first reference frequency range (925). As the sound pressure of the audio signal decreases rapidly within the first reference frequency range (925), the audio signal may be heard relatively quietly by the user, or the sound quality of the audio signal may deteriorate. At least one processor (410) can tune an audio signal in a first reference frequency range (925) to cause the audio signal in the first reference frequency range (925) to be heard relatively loudly by the user, or to enhance (or improve) the sound quality of the audio signal in the first reference frequency range (925). At least one processor (410) can enhance the user experience provided through a foldable electronic device (100) having a triangular prism shape by tuning an audio signal in the first reference frequency range (925).

[0138] For example, a dip in the sound pressure of the audio signal represented by the second line (920) may occur (or be caused) within the second reference frequency range (930). The dip in the sound pressure of the audio signal may occur (or be caused) by destructive interference of the audio signal output through the speaker (315) while the foldable electronic device (100) having a triangular prism shape is in the second position. The sound pressure of the audio signal represented by the second line (920) may decrease rapidly within the second reference frequency range (930). As the sound pressure of the audio signal decreases rapidly within the second reference frequency range (930), the audio signal may be heard relatively quietly by the user, or the sound quality of the audio signal may deteriorate. At least one processor (410) can tune an audio signal in a second reference frequency range (930) to cause the audio signal in the second reference frequency range (930) to be heard relatively loudly by the user, or to enhance (or improve) the sound quality of the audio signal in the second reference frequency range (930).
