Description

An electronic device that outputs audio

[0001] The present disclosure relates to an electronic device that outputs audio.

[0002] With the development of electronic devices that provide various functions, such as mobile communication terminals, smartphones, tablet personal computers (PCs), and laptop computers, various wearable devices (e.g., earphones, headsets, smartwatches, or smart glasses) have emerged that can be connected to other electronic devices or used independently. Wireless audio output devices (e.g., wireless earphones) can receive audio data from electronic devices such as smartphones via wireless communication. Because wireless audio output devices do not include cables for electrical connection, they may be equipped with a battery to provide the necessary power. The electronic device and the wireless audio output device may be connected via a wired interface (e.g., a connector connection) or a wireless interface (e.g., a Bluetooth™ connection). The wireless audio output device may include double-ear, detachable wireless earphones that operate in pairs. For example, wireless earphones may include a first earbud (or earpiece) and a second earbud, each worn on a user's left and right ears.

[0003] The wireless audio output device may be stored within a separate electronic device (e.g., a charging case) to prevent loss while not in use, and the battery of the wireless audio output device may be charged while the wireless audio output device is stored within the separate electronic device. For example, the wireless audio output device may be stored by being at least partially inserted and seated within a recess or receiving space provided within the separate electronic device, and the battery of the wireless audio output device may be charged by electrically connecting the conductive pins arranged within the separate electronic device to the conductive connector of the wireless audio output device by making contact.

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

[0006] According to an embodiment of the present invention, an electronic device for outputting audio may include a case including a first wearable audio output device and a first receiving portion for accommodating the first wearable audio output device. The first receiving portion may include a first recess for accommodating a first portion of the first wearable audio output device, and a second recess for accommodating a second portion of the first wearable audio output device. The second recess may include a first space and a second space extending from the first space. While the first receiving portion accommodates the first wearable audio output device, the second portion of the first wearable audio output device may fill the first space, and the second space may be empty. The second recess may be formed such that, when the first wearable audio output device is pulled out from the case, the first wearable audio output device is pulled out in an obliquely upward direction. The curved inner surface of the second recess may be formed so that the first wearable audio output device rotates by a predetermined angle about the longitudinal direction of the first wearable audio output device as the first wearable audio output device is drawn out obliquely upward from the case.

[0007] According to an embodiment of the present invention, a case for accommodating a wearable audio output device may include a receiving portion for accommodating the wearable audio output device. The receiving portion may include a plurality of recesses in which the wearable audio output device is received. The plurality of recesses may include a first recess for accommodating a first portion of the wearable audio output device, and a second recess for accommodating a second portion of the wearable audio output device. The second recess may include a first space and a second space extending from the first space. While the receiving portion receives the wearable audio output device, the second portion of the wearable audio output device may fill the first space, and the second space may be empty. The second recess may be formed such that, when the wearable audio output device is pulled out from the case, the wearable audio output device is pulled out in an obliquely upward direction. The curved inner surface of the second recess may be formed so that the wearable audio output device rotates by a certain angle about the longitudinal direction of the wearable audio output device as the wearable audio output device is drawn out obliquely upward from the case.

[0046] Referring to FIGS. 1 to 6, the electronic device (1) may include a case (100) including a receiving portion (120), a housing (110), and a cover (130).

[0047] According to one embodiment, the receiving portion (120) may include a bracket (200), a rear guide portion (300), a front guide portion (400), and a mounting portion (500). The bracket (200) may include an upper guide portion (e.g., an upper guide portion (240) of FIGS. 24 to 26). In the present disclosure, the bracket (200), the rear guide portion (300), and the front guide portion (400) are expressed as separate terms, but this is for convenience in describing the configuration according to the present disclosure, and does not mean that the bracket (200), the rear guide portion (30), and the front guide portion (400) are limited to separate and distinct configurations. For example, in the present disclosure, the bracket (200) may be a term for expressing configurations forming a part of the receiving portion (120). In addition, in the present disclosure, the bracket (200), the rear guide portion (300), the front guide portion (400), and the mounting portion (500) included in the receiving portion (120) are illustrated as being separate materials, but are not limited thereto. For example, the bracket (200), the rear guide portion (300), the front guide portion (400), and the mounting portion (500) included in the receiving portion (120) may form at least a portion of the receiving portion (120) as an integral part. For example, as a component of the receiving portion (120), at least one of the rear guide portion (300), the front guide portion (400), or the bracket (200) may be omitted, or other components may be further included. The shape of the rear guide portion (300) will be described in detail with reference to FIG. 10. The shape of the front guide portion (400) will be described in detail with reference to FIG. 13. The shape of the upper surface guide portion (240) will be described in detail with reference to FIGS. 24 and 25.

[0048] According to one embodiment, referring to FIG. 1, the receiving portion (120) may be formed symmetrically based on an imaginary plane including the line A-A'. Hereinafter, in the present disclosure, a portion forming one area of ​​the receiving portion (120) in the third direction (-y) based on the line A-A' of FIG. 1 may be referred to as a 'first receiving portion (120)', and a portion forming another area of ​​the receiving portion (120) in the fourth direction (+y) may be referred to as a 'second receiving portion (120)'. In the present disclosure, the first receiving portion (120) and the second receiving portion (120) are not separately illustrated with separate reference numerals, but it should be understood that the case (100) includes one receiving portion (120) including the first receiving portion (120) and the second receiving portion (120). In addition, as will be described later, the first receiving portion (120) can provide a space in which the first wearable audio output device (1001) is received, and the second receiving portion (120) can provide a space in which the second wearable audio output device (1002) is received.

[0049] According to one embodiment, the receiving portion (120) may include a bracket (200) formed so that a wearable audio output device (e.g., the wearable audio output device (1000) of FIG. 9) (or an ear piece) can be mounted thereon.

[0050] According to one embodiment, the bracket (200) may include a first recess (2101) and a third recess (2103) in which a first portion (e.g., a head (1100) of the wearable audio output device (1000) of FIG. 9) of a wearable audio output device (e.g., a wearable audio output device (1000) of FIG. 9) is mounted. In the present disclosure, a plurality of first recesses (2100) may be used as a term to collectively refer to the first recess (2101) and the third recess (2103).

[0051] According to one embodiment, the bracket (200) may form at least a portion of a second recess (221) and a fourth recess (222) that accommodate at least a portion of a second portion (e.g., a grip portion (1200) of the wearable audio output device (1000) of FIG. 9) of a wearable audio output device (e.g., a wearable audio output device (1000) of FIG. 9). For example, each of the second recess (221) and the fourth recess (222) may extend from the first recess (2101) and the third recess (2103), respectively, and may be formed to correspond to a shape of one end of the second portion (e.g., a grip portion (1200) of the wearable audio output device (1000) of FIG. 9) of the wearable audio output device (e.g., a wearable audio output device (1000) of FIG. 9), but is not limited thereto.

[0052] In the present disclosure, a plurality of second recesses (220) may be used as a term to collectively refer to the second recess (221) and the fourth recess (222).

[0053] In the present disclosure, an open shape formed on one side of the sixth direction (+z) of the receiving portion (120) by the second recess (221) and the fourth recess (222) may be referred to as an opening. For example, in the present disclosure, the opening may refer to a shape that allows a second part (e.g., a grip portion (1200) of the wearable audio output device (1000 of FIG. 9) of the wearable audio output device (e.g., a wearable audio output device (1000) of FIG. 9) to be inserted as the case (100) receives the wearable audio output device (e.g., a wearable audio output device (1000) of FIG. 9).

[0054] According to one embodiment, the bracket (200) may include a portion (230) formed to open at least a portion of the second recess (221) and the fourth recess (222). For example, the portion (230) of the bracket (200) forming a portion of the second recess (221) and the fourth recess (222) may be formed to open at least a portion of a space (111) inside the housing (110). The space (111) may be opened in one direction (e.g., in the opposite direction from where the cover (130) is connected to the housing (110)) by the portion (230).

[0055] Hereinafter, in the present disclosure, a portion (230) of the bracket (200) formed so that the space (111) is opened in one direction (e.g., the direction opposite to the position where the cover (130) is connected to the housing (110)) may be referred to as a step portion. For example, a first step portion (e.g., a first step portion (231) of FIG. 24) and a second step portion (e.g., a second step portion (232) of FIG. 24) may correspond to a portion (230) of the bracket (200). However, in the present disclosure, although the shape of the portion (230) of the bracket (200) is illustrated as including step portions (e.g., the first step portion (231) and the second step portion (232) of FIG. 24), this does not mean that the shape of the portion (230) of the bracket (200) is limited by the illustrated step portions. For example, a portion (230) of the bracket (200) may be formed so that at least a portion of the space (111) is open without including a step.

[0056] According to one embodiment, the receiving portion (120) may form a space that receives at least a portion of a second portion (e.g., a grip portion (1200) of the wearable audio output device (1000) of FIG. 9) of a wearable audio output device (e.g., a wearable audio output device (1000) of FIG. 9). For example, the second recess (221) of the first receiving portion (120) may include a first space (e.g., a first space (331) of FIG. 11) in which a second portion (e.g., a grip portion (1201) of the first wearable audio output device (1001) of FIG. 9) of the first wearable audio output device (e.g., a first wearable audio output device (1001) of FIG. 9) is received. For example, the second recess (221) of the first receiving portion (120) may include a second space (e.g., the second space (332) of FIG. 12) in which a second portion (e.g., the grip portion (1201) of the first wearable audio output device (1001) of FIG. 9) of the first wearable audio output device (e.g., the first wearable audio output device (1001) of FIG. 9) is received when the first wearable audio output device (e.g., the first wearable audio output device (1001) of FIG. 9) is pulled out from the case (100). In the present disclosure, a space in which at least a portion of the wearable audio output device (1000) is received by the case (100) may be referred to as a “receiving space.” In the present disclosure, the space may mean a part of a space (111) that is at least partially surrounded by a part (230) of a bracket (200), a rear guide part (e.g., a rear guide part (300) of FIG. 9), a front guide part (e.g., a front guide part (400) of FIG. 9), and a mounting part (500). The shapes of the rear guide part (e.g., a rear guide part (300) of FIG. 9), the front guide part (e.g., a front guide part (400) of FIG. 9), and the mounting part (500) will be described later.

[0057] According to one embodiment, the housing (110) can accommodate at least a portion of the receiving portion (120). For example, at least a portion of the receiving portion (120) can be accommodated in a space formed by at least two portions of the housing (110) through an open side of the housing (110) (e.g., space (111) of FIG. 4).

[0058] According to one embodiment, referring to FIG. 3, a height (114) in the sixth direction (+z) of one region of the housing (110) in the first direction (-x) with respect to the space (111) inside the housing (110) may be greater than a height (115) in the sixth direction (+z) of another region of the housing (110) in the second direction (+x). For example, a slope may be formed on one side of the housing (110) extending from one region of the housing (110) in the first direction (-x) to another region of the housing (110) in the second direction (+x) with respect to the space (111) inside the housing (110).

[0059] According to one embodiment, the cover (130) can be rotated relative to the housing (110) in certain directions (the first rotation direction (+a) of FIG. 1, the second rotation direction (-a) of FIG. 1) and within a certain angular range (p) with respect to the axis (X). For example, the cover (130) can be coupled to one side of the housing (110) or the receiving portion (120) so as to be rotatable through a hinge portion (the hinge portion (131) of FIG. 2).

[0060] According to one embodiment, the case (100) may include a hinge portion (131) that connects the cover (130) to the housing (110) or the receiving portion (120). For example, the cover (130) may be rotated in a first rotational direction (-a) or a second rotational direction (+a) within a range of 90 degrees to 180 degrees about the axis X of FIG. 1. However, the range of the rotatable angle of the cover (130) is not limited thereto and may vary depending on the shapes of individual components of the case (100).

[0061] According to one embodiment, the hinge portion (131) may be formed on one side of the bracket (200), but is not limited thereto. For example, the hinge portion (131) may be formed separately from the bracket (200) or the housing (110) and configured to be coupled to the bracket (200) or the housing (110). In the present disclosure, for the convenience of explanation, the structure connecting the cover (130) to the housing (110) is described as the term “hinge portion,” but the hinge portion (131) may be formed with another structure for connecting the cover (130) to the housing (110).

[0062] In the present disclosure, a state in which the cover (130) is rotated in the first rotational direction (-a) within a certain angle range so that at least a portion of the receiving portion (120) is exposed to the outside of the case (100) may be referred to as an open state of the cover (130). In one embodiment, the open state of the cover (130) of the case (100) may correspond to the state of the electronic device of FIGS. 1, 2, and 3. For example, in the open state of the cover (130), at least a portion of one side (210) of the bracket (200) may be exposed to the outside of the case (100). For example, in the open state of the cover (130), a plurality of first recesses (2100) forming one side of the receiving portion (120) in the sixth direction (+z) may be exposed to the outside. The plurality of first recesses (2100) forming one side of the receiving portion (120) in the sixth direction (+z) will be described later.

[0063] In the present disclosure, a state in which the cover (130) is rotated in the first rotational direction (+a) and at least a portion of the receiving portion (120) is covered by the cover (130) may be referred to as a closed state. In one embodiment, the closed state of the cover (130) of the case (100) may correspond to the state of the case (100) of FIG. 6. A case in which at least a portion of the receiving portion (120) received in the housing (110) is visible to the outside of the case (100) through the cover (130) in a closed state of the cover (130) will be described in detail with reference to FIGS. 34 and 35.

[0064] According to one embodiment, the case (100) may include at least one conductive pin (510) disposed in a mounting portion (e.g., mounting portion (500) of FIG. 2, mounting portion (500) of FIG. 4). For example, at least one conductive pin (510) may be disposed in at least one through hole (e.g., at least one first through hole (521) of FIG. 30) of the mounting portion (500).

[0065] According to one embodiment, the battery of a wearable audio output device (e.g., the wearable audio output device (1000) of FIG. 9) may be charged by electrical contact with at least one conductive pin (510) disposed on a mounting portion (500) of a case (100). The shape of the case (100) for charging the battery of the wearable audio output device (e.g., the wearable audio output device (1000) of FIG. 9) through the conductive pin (510) will be described in detail with reference to FIGS. 30 and 31, which will be described later.

[0066] FIG. 7 is a diagram illustrating a first wearable audio output device and a second wearable audio output device according to one embodiment.

[0067] According to one embodiment, a wearable audio output device (1000) accommodated in a case (100) may include a first wearable audio output device (1001) and a second wearable audio output device (1002).

For example, the head (1100) may include a first head (1101) forming at least a portion of a first wearable audio output device (1001), and a second head (1102) forming at least a portion of a second wearable audio output device (1002). For example, the grip portion (1200) may include a first grip portion (1201) extending from the first head (1101), and a second grip portion (1202) extending from the second head (1102). In the present disclosure, the head (1100) may be referred to as a first part (1100) of the wearable audio output device (1000). In the present disclosure, the grip portion (1200) may be referred to as a second part (1200) of the wearable audio output device (1000). In one embodiment, a cross-section of the grip portion (1200) perpendicular to the direction in which the grip portion (1200) extends from the head (1100) may have a shape other than a circle. However, the shape of the grip portion (1200) is not limited to the shape illustrated in FIG. 7.

[0069] According to one embodiment, the first wearable audio output device (1001) and the second wearable audio output device (1002) can perform wireless communication with another electronic device through wireless communication (e.g., Bluetooth).

[0072] According to one embodiment, the wearable audio output device (1000) may have a head (1100) accommodated in a first recess (e.g., the first recess (2101) of FIG. 1) or a third recess (e.g., the third recess (2103) of FIG. 1) of the case (100), and at least a portion of a grip portion (1200) of the wearable audio output device (1000) may be accommodated in a second recess (e.g., the second recess (221) of FIG. 1) or a fourth recess (e.g., the fourth recess (222) of FIG. 1) of the case (100). For example, the first wearable audio output device (1001) may be accommodated in the case (100) by having at least a portion of the first head (1101) accommodated in a first recess (e.g., the first recess (2101) of FIG. 1) and the first grip portion (1201) accommodated in a second recess (e.g., the second recess (221) of FIG. 1).

[0073] According to one embodiment, the second wearable audio output device (1002) may be accommodated in the case (100) by having at least a portion of the second head (1102) accommodated in a third recess (e.g., the third recess (2103) of FIG. 1) and the second grip portion (1202) accommodated in a fourth recess (e.g., the fourth recess (222) of FIG. 1).

[0074] According to one embodiment, as the first wearable audio output device (1001) and the second wearable audio output device (1002) are accommodated in the case (100), the first wearable audio output device (1001) and the second wearable audio output device (1002) can be positioned symmetrically about the line A-A' of FIG. 1.

[0075] According to one embodiment, as the wearable audio output device (1000) is accommodated in the case (100), at least a portion of the head (1100) of the wearable audio output device (1000) may be positioned higher than the bracket (200) and thus may protrude in a sixth direction (+z) with respect to the bracket (200). A user may pick up at least a portion of the protruding head (1100) with fingers to pull the wearable audio output device (1000) out of the case (100).

[0076] According to one embodiment, as the wearable audio output device (1000) is accommodated in the case (100), at least a portion (1250) of the grip portion (1200) of the wearable audio output device (1000) accommodated in the case (100) may be exposed to the outside of the case (100) in the second direction (+x) with respect to the bracket (200). For example, with respect to the space inside the housing (110) (e.g., the space (111) inside the housing (110) of FIG. 4), the height (115) in the z direction of a region of the housing (110) in the second direction (+x) may be smaller than the height (122) in the z direction of a region of the bracket (200) in the second direction (+x). For example, when the grip portion (1200) is accommodated in the case (100) based on the entire length of the grip portion (1200), a part of the grip portion (1200) (e.g., one-third of the length of the grip portion (1200)) from one side of the grip portion (1200) in the fifth direction (-z) may be covered by one side of the housing (110) in the second direction (+x) based on the bracket (200) when viewed in the -x-axis direction. A remaining part of the grip portion (1200) from the other side adjacent to the head (1100) of the grip portion (1200) in the sixth direction (+z) may be exposed to the outside of the case (100) in the second direction (+x) based on the bracket (200). For example, the size in the z direction of a region of the grip portion (1200) exposed to the outside of the case (100) may be greater than the difference between the height (115) in the z direction of a region of the housing (110) in the second direction (+x) based on the space (111) inside the receiving portion (120) and the height (122) in the z direction of a region of the bracket (200) in the second direction (+x).

[0077] According to one embodiment, at least a part of the wearable audio output device (1000) accommodated in the case (100) when the cover (130) is closed may be covered by the case (100) and may not be visible from the outside of the case (100). According to one embodiment, when the cover (130) includes a transparent material, at least a part of the wearable audio output device (1000) accommodated in the case (100) when the cover (130) is closed may be visible from the outside of the case (100) through the cover (130). A case in which at least a part of the wearable audio output device (1000) accommodated in the case (100) when the cover (130) is closed is visible from the outside of the case (100) through the cover (130) will be described in detail with reference to FIGS. 34 and 35.

[0078] Fig. 10 is a perspective view illustrating a rear guide portion and a mounting portion according to an embodiment. Fig. 11 is a cross-sectional view illustrating an electronic device in which a first wearable audio output device is accommodated in the electronic device, and the first wearable audio output device, taken along the line A-A' of Fig. 1 according to an embodiment. Fig. 12 is a cross-sectional view illustrating an electronic device in which the first wearable audio output device is being pulled out from the electronic device, and the first wearable audio output device, taken along the line A-A' of Fig. 1 according to an embodiment.

[0079] Referring to FIGS. 10, 11, and 12, the case (100) may include a rear guide portion (300) and a mounting portion (500). In the present disclosure, the rear guide portion (300) and the mounting portion (500) are expressed as being formed integrally, but are not limited thereto. For example, the mounting portion (500) may form at least a portion of the receiving portion (120) as a separate component from the rear guide portion (300). According to one embodiment, at least a portion of the rear guide portion (300) may be formed by extending from the first recess (2101) and the third recess (2103). For example, the rear guide portion (300) may be disposed on one side of the bracket (200). For example, the first rear guide portion (301) may include a surface formed by extending from the first recess (e.g., the first recess (2101) of FIG. 1). For example, the first rear guide portion (301) may be arranged in a first direction (-x) with respect to the first space (the first space (331) of FIG. 11). For example, the second rear guide portion (302) may include a surface formed by extending from a third recess (e.g., the third recess (2103) of FIG. 1). For example, the second rear guide portion (302) may include a surface arranged in the first direction (-x) with respect to the third space (not shown). For example, in the present disclosure, the first rear guide portion (301) and the second rear guide portion (302) may have a symmetrical shape with respect to an imaginary surface including the line A-A' of FIG. 1 and extending in the z direction. Hereinafter, the description of the first rear guide part (301) and the configurations of the first rear guide part (301) in the present disclosure can be equally applied to the second rear guide part (302) and the configurations included in the second rear guide part (302).

[0080] According to one embodiment, referring to FIG. 10, the rear guide portion (300) may include a first curved surface (311), a fourth curved surface (314), a first mounting surface (321), and a fourth mounting surface (324).

[0081] According to one embodiment, the first curved surface (311) may form at least a portion of a first space (331) that accommodates at least a portion of the first grip portion (1201) of the first wearable audio output device (1001). For example, the first curved surface (311) may include a shape that is sunken in the first direction (-x) in the first space (331) in which the first grip portion (1201) of the first wearable audio output device (1001) is accommodated. For example, the first curved surface (311) may extend from the first recess (2101) in a direction having a component in the fifth direction (-z) to form at least a portion of the second recess (221). According to one embodiment, the first mounting surface (321) may be formed to extend in a fifth direction (-z) away from the first recess (2101) from the first curved surface (311) so that at least a portion of the first grip portion (1201) of the first wearable audio output device (1001) is mounted thereon. For example, the shape of the first mounting surface (321) may be formed to correspond to the shape of at least a portion of the first grip portion (1201) disposed toward the first direction (-x) based on a state in which the first wearable audio output device (1001) is accommodated in the case (100). For example, when at least a portion of the shape of the first grip portion (1201) arranged toward the first direction (-x) is formed as a curved surface based on the state in which the first wearable audio output device (1001) is accommodated in the case (100), at least a portion of the first mounting surface (321) may also be formed as a curved surface.

[0082] According to one embodiment, the fourth curved surface (314) may form at least a portion of a third space (not shown) that accommodates at least a portion of the second grip portion (1202) of the second wearable audio output device (1002). For example, the fourth curved surface (314) may include a shape that is sunken in the first direction (-x) in the fourth space where the second grip portion (1202) of the second wearable audio output device (1002) is accommodated. For example, the fourth curved surface (314) may extend from the third recess (2103) in a direction having a component in the fifth direction (-z) to form at least a portion of the fourth recess (222).

[0083] According to one embodiment, the fourth mounting surface (324) may be formed to extend in a fifth direction (-z) away from the third recess (2103) from the fourth curved surface (314) so ​​as to allow at least a portion of the second grip portion (1202) of the second wearable audio output device (1002) to be mounted thereon. For example, the shape of the fourth mounting surface (324) may be formed to correspond to the shape of at least a portion of the second grip portion (1202) disposed toward the first direction (-x) based on a state in which the second wearable audio output device (1002) is accommodated in the case (100). For example, when at least a portion of the shape of the second grip portion (1202) arranged toward the first direction (-x) is formed as a curved surface based on the state in which the second wearable audio output device (1002) is accommodated in the case (100), at least a portion of the fourth mounting surface (324) may also be formed as a curved surface.

[0084] According to one embodiment, the friction coefficient of the first seating surface (321) of the rear guide portion (300) may be greater than the friction coefficient of the first curved surface (311). According to one embodiment, the friction coefficient of the fourth seating surface (324) of the rear guide portion (300) may be greater than the friction coefficient of the fourth curved surface (314). Since the coefficient of friction of the first mounting surface (321) and the fourth mounting surface (324) of the rear guide portion (300) is greater than the coefficient of friction of the first curved surface (311) and the fourth curved surface (314), when the first wearable audio output device (1001) or the second wearable audio output device (1002) is accommodated in the case (100) and an impact or vibration is applied to the case (100) from the outside, the first wearable audio output device (1001) or the second wearable audio output device (1002) can be prevented from being separated from the case (100) regardless of the user's intention. Since the friction coefficients of the first curved surface (311) and the fourth curved surface (314) of the rear guide portion (300) are smaller than the friction coefficients of the first mounting surface (321) and the fourth mounting surface (324), the first wearable audio output device (1001) or the second wearable audio output device (1002) can be pulled out more smoothly from the case (100). In addition, since the coefficient of friction of the first curved surface (311) and the fourth curved surface (314) of the rear guide portion (300) is smaller than the coefficient of friction of the first mounting surface (321) and the fourth mounting surface (324), it is possible to prevent or reduce damage to the case (100), the first wearable audio output device (1001), or the second wearable audio output device (1002) due to contact between one side of the receiving portion (120) of the case (100) and the first wearable audio output device (1001) or the second wearable audio output device (1002) drawn out from the case (100).

[0085] In the present disclosure, the shapes of the first curved surface (311), the first mounting surface (321), the fourth curved surface (314), and the fourth mounting surface (324) are not limited to the embodiments shown in the drawings, and in accordance with the shape and size of the grip portion (1200) of the wearable audio output device (1000), the first curved surface (311), the first mounting surface (321), the fourth curved surface (314), and the fourth mounting surface (324) can be formed to have various directions and curvatures.

[0086] According to one embodiment, referring to FIG. 11, while the first receiving portion (120) accommodates the first wearable audio output device (1001), the second portion (1201) of the first wearable audio output device (1001) may fill the first space (331). For example, while the first receiving portion (120) accommodates the first wearable audio output device (1001), the second portion (1201) of the first wearable audio output device (1001) may be accommodated in the first space (331). For example, the first space (331) may be a space occupied by the first grip portion (1201) of the first wearable audio output device (1001) among the accommodation spaces of the case (100) in which the first wearable audio output device (1001) is accommodated. For example, the shape of the first space (331) may correspond to the shape of the first grip portion (1201) of the first wearable audio output device (1001). For example, the size of a cross-section including the x-direction and the y-direction of the first space (331) may be at least larger than the size of the area of ​​the end of the first grip portion (1201) of the first wearable audio output device (1001). According to one embodiment, while the second receiving portion (120) receives the second wearable audio output device (1002), the second part (1202) of the second wearable audio output device (1002) may fill the third space (not shown). This can be understood in the same manner as the description of the first space (331) described above.

[0087] According to one embodiment, referring to FIG. 11, while the first receiving portion (120) receives the first wearable audio output device (1001), the second space (332) of the first receiving portion (120) may be empty. For example, the second space (332) may refer to a space not occupied by the first grip portion (1201) of the first wearable audio output device (1001) while the first receiving portion (120) receives the first wearable audio output device (1001), among the spaces formed by the second recess (e.g., the second recess (221) of FIG. 1). For example, the second space (332) may be a space formed by a shape that is sunken in the first direction (-x) with respect to the receiving space of the first rear guide portion (301). According to one embodiment, while the second receiving portion (120) accommodates the second wearable audio output device (1002), the fourth space (not shown) may be empty. This may be understood in the same manner as the description regarding the second space (332) described above. According to one embodiment, during the process of taking the wearable audio output device (1000) out of the case (100), the wearable audio output device (1000) may be tilted in a specific direction. For example, the rear guide portion (301) may provide a second space (332) in the first direction (-x) based on the receiving space so that at least a portion of the first grip portion (1201) can move in an eighth direction (1502) opposite to the seventh direction (1501) within the receiving space so that the first wearable audio output device (1001) can be tilted in the seventh direction (1501) as the first wearable audio output device (1001) is inserted into the case (100) or as the first wearable audio output device (1001) is withdrawn from the case (100).Accordingly, as the first wearable audio output device (1001) is pulled out from the case (100), the first wearable audio output device (1001) can be tilted in a seventh direction (1501) including at least a component of the second direction (+x) and the fifth direction (-z). For example, when the first wearable audio output device (1001) is pulled out from the case (100), an end of the first grip portion (1201) of the first wearable audio output device (1001) can be accommodated in the second space (332).

[0088] According to one embodiment, as the first wearable audio output device (1001) is pulled out from the case (100), the first wearable audio output device (1001) may be pulled out in a ninth direction (1503). For example, referring to FIG. 12, the ninth direction (1503) may be a direction including a component in the second direction (+x) and a component in the sixth direction (+z). In the present disclosure, the seventh direction (1501) is illustrated as a vector having a fixed magnitude including components in the second direction (+x) and the fifth direction (-z), but the magnitude and direction components of the seventh direction (1501) may dynamically change. For example, the seventh direction (1501) may include a component in the third direction (-y). For example, as the first wearable audio output device (1001) is pulled out from the case (100), the size of the x-direction, y-direction, or z-direction of the seventh direction (1501) may dynamically change. In the present disclosure, the ninth direction (1503) is illustrated as a one-directional vector having a fixed size including components in the second direction (+x) and the sixth direction (+z), but the components of the size and direction of the ninth direction (1503) may dynamically change. For example, the ninth direction (1503) may include a component in the third direction (-y). For example, as the first wearable audio output device (1001) is pulled out from the case (100), the size of the components of the x-direction, y-direction, or z-direction of the ninth direction (1501) may dynamically change.

[0089] In the present disclosure, for convenience, the seventh direction (1501) may be referred to as an oblique downward direction (1501), and the ninth direction (1503) may be referred to as an oblique upward direction (1503).

[0090] In FIG. 12, only the motion of tilting in the seventh direction (1501) as the first wearable audio output device (1001) is pulled out from the case (100) is illustrated, but the second rear guide portion (302) can provide the same function even when the second wearable audio output device (1002) is pulled out from the case (100). For example, since the second rear guide part (302) has a shape symmetrical with respect to the line A-A' of FIG. 1 with respect to the first rear guide part (301), the second rear guide part (302) can provide a fourth space (not shown) that allows the second wearable audio output device (1002) to tilt in a direction symmetrical with respect to the line A-A' of FIG. 1 while the first wearable audio output device (1001) is tilted as the second wearable audio output device (1002) is pulled out from the case (100).

[0091] According to one embodiment, the mounting portion (500) may be formed by extending from a region of the rear guide portion (300) where the mounting surface (320) is formed. For example, the first mounting portion (501) may extend in a first direction (-x) from a region of the first rear guide portion (301) where the first mounting surface (321) is formed to form one side of a second recess (e.g., the second recess (221) of FIG. 1). For example, the second mounting portion (502) may extend in a first direction (-x) from a region of the second rear guide portion (302) where the fourth mounting surface (324) is formed to form one side of a fourth recess (e.g., the fourth recess (222) of FIG. 1).

[0092] According to one embodiment, the mounting portion (500) may include at least one through hole (520) in which at least one conductive pin (e.g., the conductive pin (510) of FIG. 2) may be disposed. For example, at least one conductive pin (510) may be exposed to the receiving space through at least one through hole (520) formed in the mounting portion. For example, at least one through hole (520) formed in the mounting portion (500) may be formed to correspond to a shape of a portion of at least one conductive pin (e.g., the conductive pin (510) of FIG. 2). The wearable audio output device (1000) and the case (100) may be electrically connected when the conductive connector (1300) disposed at one end of the grip portion (1200) of the wearable audio output device (1000) disposed in the receiving space and the conductive pin (510) disposed at one side of the mounting portion (500) come into contact. The configuration of the case (100) in which the wearable audio output device (1000) and the case (100) are electrically connected to charge the battery of the wearable audio output device (1000) will be described in detail with reference to FIGS. 30 and 31.

[0093] Fig. 13 is a perspective view illustrating a front guide part according to an embodiment. Fig. 14 is a front view illustrating a front guide part according to an embodiment. Fig. 15 is a plan view illustrating a front guide part according to an embodiment. Fig. 16 is a rear view illustrating a front guide part according to an embodiment. Fig. 17 is a cross-sectional view illustrating a surface taken along line D-D' of Fig. 14 of the front guide part according to an embodiment. Fig. 18 is a cross-sectional view illustrating a surface taken along line E-E' of Fig. 14 of the front guide part according to an embodiment.

[0094] Referring to FIGS. 13 to 18, the front guide portion (400) may include a first front guide portion (401) and a second front guide portion (402), which form at least one inclined surface (410). For example, the first front guide portion (401) may include a first protrusion portion (431) and a second protrusion portion (432). For example, the second front guide portion (402) may include a third protrusion portion (433) and a fourth protrusion portion (434). For example, the second protrusion portion (432) and the fourth protrusion portion (434) may form one protrusion portion as a single unit.

[0095] According to one embodiment, the first protrusion (431) may protrude in one direction including a component in the first direction (-x) from an area of ​​the first front guide portion (401) forming at least a portion of the first space (e.g., the first space (331) of FIG. 11) in which the first wearable audio output device (1001) is accommodated, to form a first inclined surface (411). According to one embodiment, the first protrusion (431) may include a second mounting surface (422) formed by extending in a third direction (-y) from the first inclined surface (411).

[0096] According to one embodiment, the third protrusion (433) may protrude in one direction including a component in the first direction (-x) from an area of ​​the second front guide portion (402) forming at least a portion of a third space (not shown) in which the second wearable audio output device (1002) is accommodated, thereby forming a second inclined surface (412). According to one embodiment, the third protrusion (433) may include a fifth mounting surface (425) formed by extending in a fourth direction (+y) from the second inclined surface (412).

[0097] According to one embodiment, the coefficient of friction of the second seating surface (422) and the fifth seating surface (425) may be greater than the coefficient of friction of the first inclined surface (411) and the second inclined surface (412). For example, the second seating surface (422) and the fifth seating surface (425) may be formed of a material having a greater coefficient of friction than the first inclined surface (411) and the second inclined surface (412). For example, the second seating surface (422) and the fifth seating surface (425) may be formed of a urethane material. Since the friction coefficients of the second mounting surface (422) and the fifth mounting surface (425) are greater than the friction coefficients of the first inclined surface (411) and the second inclined surface (412), when the first wearable audio output device (1001) or the second wearable audio output device (1002) is accommodated in the case (100), the first wearable audio output device (1001) or the second wearable audio output device (1002) can be prevented from being separated from the case (100) regardless of the user's intention.

[0098] In one embodiment, the first inclined surface (411) and the second inclined surface (412) may have a lower coefficient of friction than the second seating surface (422) and the fifth seating surface (425). For example, the first inclined surface (411) and the second inclined surface (412) may be formed through a mold and may have a lower coefficient of friction than the coefficients of friction of the second seating surface (422) and the fifth seating surface (425). For example, a paint may be applied to at least one of the first inclined surface (411) or the second seating surface (422) so that the first inclined surface (411) may have a lower coefficient of friction than the second seating surface (422). For example, different paints may be applied to the first inclined surface (411) and the second seating surface (422) so that the first inclined surface (411) may have a lower coefficient of friction than the second seating surface (422). For example, paint may be applied to at least one of the second inclined surface (412) or the fifth seating surface (425) so that the second inclined surface (412) has a lower coefficient of friction than the fifth seating surface (425). For example, different paints may be applied to the second inclined surface (412) and the fifth seating surface (425) so that the second inclined surface (412) has a lower coefficient of friction than the fifth seating surface (425). Since the first inclined surface (411) and the second inclined surface (412) have a relatively low coefficient of friction, the first wearable audio output device (1001) or the second wearable audio output device (1002) can be easily pulled out from the case (1000). The first inclined surface (411) and the second inclined surface (412) having a low coefficient of friction can prevent or reduce a phenomenon in which one side of the case (100), the first wearable audio output device (1001), or the second wearable audio output device (1002) is damaged due to contact between the first inclined surface (411) and the first wearable audio output device (1001) pulled out from the case (100), or between the second inclined surface (412) and the second wearable audio output device (1002) pulled out from the case (100).

[0099] According to one embodiment, the second protrusion (432) and the fourth protrusion (434) may be formed to be positioned between the first protrusion (431) and the third protrusion (433) and protrude in the first direction (-x) from one surface of the front guide portion (400).

[0100] According to one embodiment, the first protrusion (431) and the third protrusion (433) may have a shape that protrudes further in the first direction (-x) in the receiving space than the second protrusion (432) and the fourth protrusion (434), but is not limited thereto.

[0101] Fig. 19 is a right side view illustrating a front guide part according to one embodiment. Fig. 20 is a left side view illustrating a front guide part according to one embodiment.

[0102] Referring to FIGS. 19 and 20, the degree of protrusion of the portion adjacent to the mounting portion (500) of the first protrusion (431) and the third protrusion (433) may be greater than the degree of protrusion of the portion adjacent to the first recess (e.g., the first recess (2101) of FIG. 1) and the third recess (e.g., the third recess (2103) of FIG. 1) of the first protrusion (431) and the third protrusion (433).

[0103] According to one embodiment, one area (4315) of the first protrusion (431) may protrude further in the first direction (-x) than the other area (4316) of the first protrusion (431). For example, since one area (4315) of the first protrusion (431) protrudes further in the first direction (-x) than the other area (4316) of the first protrusion (431) in the sixth direction (+z), the lower portion of the first grip portion (1201) may be stably fixed when the first wearable audio output device (1001) is accommodated in the case (100). For example, since one area (4316) of the first protrusion (431) protrudes further in the first direction (-x) than the other area (4315) of the first protrusion (431), a space (space (4341) of FIG. 19) in which the first grip portion (1201) of the first wearable audio output device (1001) can tilt can be secured as the first wearable audio output device (1001) moves in the sixth direction (+z) in the receiving space.

[0104] In one embodiment, the first inclined surface (411) may be formed such that the width (4415) of the portion adjacent to the mounting portion (500) is greater than the width (4416) of the portion adjacent to the first recess (e.g., the first recess (2101) of FIG. 1). In the process in which the first wearable audio output device (1001) moves in the sixth direction (+z), the first wearable audio output device (1001) may rotate about the longitudinal direction of the first grip portion (1201) of the first wearable audio output device (1001) by the first inclined surface (411). Hereinafter, in the present disclosure, the longitudinal direction of the first grip portion (1201) may correspond to the line R-R' of FIG. 21, but is not limited to the illustrated example. For example, the longitudinal direction of the first grip portion (1201) may dynamically change as the first wearable audio output device (1001) is pulled out from or inserted into the case (100). For example, the longitudinal direction of the first grip portion (1201) may refer to the direction in which the first grip portion (1201) extends from the first head (1101).

[0105] According to one embodiment, one area (4335) of the third protrusion (433) may protrude further in the first direction (-x) than the other area (4336) of the third protrusion (433). The effect of one area (4335) of the third protrusion (433) protruding further in the first direction (-x) than the other area (4336) of the third protrusion (433) may be understood in correspondence to the effect of one area (4315) of the first protrusion (431) protruding further in the first direction (-x) than the other area (4316) of the first protrusion (431). For example, as the second wearable audio output device (1002) moves in the sixth direction (+z) in the receiving space, a space (space (4342) of FIG. 20) in which the second grip portion (1202) of the second wearable audio output device (1002) can tilt can be secured.

[0106] In one embodiment, the second inclined surface (412) may be formed such that the width (4425) of the portion adjacent to the mounting portion (500) is greater than the width (4426) of the portion adjacent to the third recess (e.g., the third recess (2103) of FIG. 1). In the process of the second wearable audio output device (1002) moving in the sixth direction (+z), the second wearable audio output device (1002) may rotate about the longitudinal direction of the second grip portion (1202) of the second wearable audio output device (1002) by the second inclined surface (412). Hereinafter, in the present disclosure, the longitudinal direction of the second grip portion (1202) may be understood as corresponding to the longitudinal direction of the first grip portion (1201) described above along the line RR` of FIG. 21. For example, the longitudinal direction of the second grip portion (1202) may mean a direction symmetrical to the longitudinal direction of the first grip portion (1201) with respect to the virtual surface.

[0107] FIG. 21 is a drawing for explaining the role of a front guide portion that induces the first wearable audio output device to rotate as the first wearable audio output device accommodated in the case is pulled out from the case according to one embodiment.

[0108] Referring to FIG. 21, the front guide portion (400) can guide the wearable audio output device (1000) to rotate in a predetermined rotational direction and by a predetermined angle around the longitudinal direction of the first wearable audio output device (1001) as the wearable audio output device (1000) is pulled out from the case (100).

[0109] According to one embodiment, as the first wearable audio output device (1001) is pulled out from the case (100), the first wearable audio output device (1001) can move a predetermined distance in the sixth direction (+z) along one side of the first protrusion (431), as shown in the first state (491) of FIG. 21. As the first wearable audio output device (1001) is pulled out from the case (100) from the first state (491), the first wearable audio output device (1001) can rotate a predetermined angle in the third rotational direction (r) about the line R-R' as an axis, as shown in the second state (492) of FIG. 21. As the first wearable audio output device (1001) is withdrawn from the case (100) from the second state (492), the first wearable audio output device (1001) can be withdrawn while further tilting in the incline direction of the first inclined surface (411) as shown in the third state (493) of FIG. 21. The first front guide portion (401) can be configured to induce moving motions during the process of the first wearable audio output device (1001) being withdrawn from the case (100).

[0110] In the present disclosure, only the operation in which the wearable audio output device (1000) is withdrawn from the case (100) has been described, but a series of operations of the wearable audio output device (1000) as the wearable audio output device (1000) is received into the case (100) can be understood in the reverse order of a series of operations in which the wearable audio output device (1000) rotates as the wearable audio output device (1000) is withdrawn from the case (100).

[0111] In the present disclosure, only a series of operations for rotating the first wearable audio output device (1001) as it is pulled out from the case (1001) has been described, but a series of operations for rotating the second wearable audio output device (1002) as it is pulled out from the case (100) can also be understood by the same principle. For example, a series of operations for rotating the first wearable audio output device (1001) as it is pulled out from the case (100) and a series of operations for rotating the second wearable audio output device (1002) as it is pulled out from the case (100) can be understood as operations that are symmetrical with respect to the line A-A' of FIG. 1.

[0112] In the present disclosure, the withdrawal operations of the first wearable audio output device (1001) are expressed as discrete individual states, but a series of operations in which the first wearable audio output device (1001) is withdrawn from the case (100) may be continuously continued. In addition, the operation of moving in a specific direction, rotating, or tilting as the first wearable audio output device (1001) is withdrawn from the case (100) may occur simultaneously, and each operation illustrated in the present disclosure does not mean that it occurs exclusively.

[0113] FIG. 22 is a cross-sectional view of an electronic device, as seen from a plane cut along line B-B' of FIG. 11, with the wearable audio output device housed in a case according to one embodiment. FIG. 23 is a cross-sectional view of an electronic device, as seen from a plane cut along line C-C' of FIG. 11, with the wearable audio output device housed in a case according to one embodiment.

[0114] Referring to FIGS. 22 and 23, the width in the x-axis direction of the receiving space formed by the receiving portion (120) of the case (100) may become smaller as the distance from the specific position to the mounting portion (500) increases from the first recess (e.g., the first recess (2101) of FIG. 1) and the third recess (e.g., the third recess (2103) of FIG. 1).

[0115] According to one embodiment, the second width in the x-axis direction of the accommodation space formed by the accommodation portion (120) in the plane cut along line C-C' of FIG. 11 (the second width (124) of FIG. 23) may be smaller than the first width in the x-axis direction of the accommodation space formed by the accommodation portion (120) in the plane cut along line B-B' of FIG. 11 (the first width (123) of FIG. 22). For example, when the grip portion (1200) of the wearable audio output device (1000) is accommodated in the case (100), the width in the x-axis direction of the accommodation space formed by the accommodation portion (120) of the case (100) becomes smaller as it moves away from the first recess (e.g., the first recess (2101) of FIG. 1) and the third recess (e.g., the third recess (2103) of FIG. 1), so the gap between the grip portion (1100) and the front guide portion (400) may become smaller as it moves away from the first recess (e.g., the first recess (2101) of FIG. 1) and the third recess (e.g., the third recess (2103) of FIG. 1). Due to this, as the wearable audio output device (1000) is accommodated in the case (100), one end of the grip portion (1100) on which the conductive connector (conductive connector (1300) of FIG. 7) is arranged can be accurately seated in the mounting portion (500) on which at least one conductive pin (at least one conductive pin (510) of FIG. 2) is arranged.

[0116] Fig. 24 is a perspective view illustrating a bracket according to one embodiment. Fig. 25 is a plan view illustrating a bracket according to one embodiment. Fig. 26 is a cross-sectional view illustrating a region of the bracket as viewed along the line F-F' in Fig. 24 according to one embodiment.

[0117] Referring to FIGS. 24 to 26, the bracket (200) may include a first recess (e.g., the first recess (2101) of FIG. 1), a third recess (e.g., the third recess (2103) of FIG. 1), and an upper guide portion (240).

[0118] According to one embodiment, the first recess (2101) may include a third mounting surface (2113) formed to allow the first head (1101) of the first wearable audio output device (1001) to be mounted thereon. For example, the third mounting surface (2113) may be formed to correspond to the shape of at least a portion of the first head (1101).

[0119] According to one embodiment, the third recess (2103) may include a sixth mounting surface (2116) formed to allow the second head (1102) of the second wearable audio output device (1002) to be mounted thereon. For example, the sixth mounting surface (2116) may be formed to correspond to the shape of at least a portion of the second head (1102).

[0120] According to one embodiment, the first recess (2101) and the third recess (2103) may be formed to be symmetrical with respect to an imaginary plane including line A-A' of FIG. 1. For example, the third mounting surface (2113) and the sixth mounting surface (2116) may be formed to be symmetrical with respect to an imaginary plane including line A-A' of FIG. 1.

[0121] According to one embodiment, the bracket (200) may be formed so that at least a portion of the receiving space in which at least a portion of the first grip portion (1201) of the first wearable audio output device (1001) formed by the receiving portion (120) is received is opened. For example, a portion (230) of the bracket (200) may be formed so that at least a portion of the second recess (e.g., the second recess (221) of FIG. 1) and the fourth recess (e.g., the fourth recess (222) of FIG. 1) are opened in the second direction (+x).

[0122] According to one embodiment, the upper surface guide portion (240) may include a first upper surface guide portion (241) and a second upper surface guide portion (242). The first upper surface guide portion (241) and the second upper surface guide portion (242) may have a shape symmetrical with respect to the line A-A' of FIG. 1 as an axis.

[0123] According to one embodiment, the first upper surface guide portion (241) may form at least a portion of the first recess (2101). For example, the first upper surface guide portion (241) may include a second curved surface (2412) formed to extend in a direction from the third seating surface (2113) toward the second recess (221) and in a second direction (+x) based on the third seating surface (2113).

[0124] According to one embodiment, the first upper guide portion (241) may form at least a portion of the second recess (221). For example, the first upper guide portion (241) may include a third curved surface (2413) extending from the second curved surface (2412) and connected to a first curved surface (e.g., the first curved surface (311) of FIG. 10) included in the first rear guide portion (e.g., the first rear guide portion (301) of FIG. 10).

[0125] According to one embodiment, the second upper surface guide portion (242) may form at least a portion of the third recess (2103). For example, the second upper surface guide portion (242) may include a fifth curved surface (2425) formed in a direction from the sixth seating surface (2116) toward the fourth recess (222) and extending in the second direction (+x) with respect to the sixth seating surface (2116).

[0126] According to one embodiment, the second upper guide portion (242) may form at least a portion of the fourth recess (222). For example, the second upper guide portion (242) may include a sixth curved surface (2426) extending from the fifth curved surface (2425) and connected to a fourth curved surface (e.g., the fourth curved surface (314) of FIG. 10) included in the second rear guide portion (e.g., the second rear guide portion (302) of FIG. 10).

[0127] In the present disclosure, the shapes of the second curved surface (2412), the third curved surface (2413), the fifth curved surface (2425), and the sixth curved surface (2426) are not limited to the embodiments expressed in the drawings, and the second curved surface (2412), the third curved surface (2413), the fifth curved surface (2425), and the sixth curved surface (2426) can be formed to have various directions and curvatures in response to the shapes and sizes of the head (1100) and the grip portion (1200) of the wearable audio output device (1000).

[0128] According to one embodiment, the second curved surface (2412) and the third curved surface (2413) may induce the first wearable audio output device (1001) to rotate by a predetermined angle in a third rotational direction (e.g., the third rotational direction (r) of FIG. 21) as the first wearable audio output device (1001) is pulled out from the case (100). For example, the rotation of the first wearable audio output device (1001) may be induced as at least a portion of one side of the first head (1101) of the first wearable audio output device (1001) slides along the second curved surface (2412) and at least a portion of one side of the first grip portion (1201) of the first wearable audio output device (1001) slides along the third curved surface (2413). In the present disclosure, only the function of inducing the second curved surface (2412) and the third curved surface (2413) to rotate as the first wearable audio output device (1001) is withdrawn from the case (100) has been described, but the function of inducing the fifth curved surface (2425) and the sixth curved surface (2426) to rotate as the second wearable audio output device (1002) is withdrawn from the case (100) can also be understood in the same way as the function of inducing the second curved surface (2412) and the third curved surface (2413) to rotate as the first wearable audio output device (1001) is withdrawn from the case (100).

[0129] According to one embodiment, the friction coefficients of the third seating surface (2113) and the sixth seating surface (2116) formed in the plurality of first recesses (2100) may be greater than the friction coefficients of the second curved surface (2412), the third curved surface (2412), the fifth curved surface (2425), and the sixth curved surface (2426) of the upper guide portion (300). Since the friction coefficients of the third mounting surface (2113) and the sixth mounting surface (2116) formed in the plurality of first recesses (2100) are greater than the friction coefficients of the second curved surface (2412), the third curved surface (2412), the fifth curved surface (2425), and the sixth curved surface (2426) of the upper guide portion (300), the first wearable audio output device (1001) or the second wearable audio output device (1002) can be maintained in a state of being stably mounted on the case (100). For example, when the first wearable audio output device (1001) and the second wearable audio output device (1002) are accommodated in the case (100), and an impact or vibration is applied to the case (100) from the outside, the third mounting surface (2113) and the sixth mounting surface (2116) can prevent the first wearable audio output device (1001) and the second wearable audio output device (1002) from being separated from the case (100) regardless of the user's intention.

[0130] According to one embodiment, the friction coefficients of the second curved surface (2412), the third curved surface (2413), the fifth curved surface (2425), and the sixth curved surface (2426) of the upper guide portion (300) may have friction coefficients lower than the friction coefficients of the third seating surface (2113) and the sixth seating surface (2116). For example, the second curved surface (2412), the third curved surface (2413), the fifth curved surface (2425), and the sixth curved surface (2426) may be formed through a mold and have friction coefficients lower than the friction coefficients of the third seating surface (2113) and the sixth seating surface (2116). For example, by applying paint to at least one of the second curved surface (2412), the third curved surface (2413), the fifth curved surface (2425), the sixth curved surface (2426), the third mounting surface (2113), or the sixth mounting surface (2116), the second curved surface (2412), the third curved surface (2413), the fifth curved surface (2425), and the sixth curved surface (2426) can be formed to have a coefficient of friction higher than that of the third mounting surface (2113) and the sixth mounting surface (2116). Since the friction coefficients of the second curved surface (2412), the third curved surface (2413), the fifth curved surface (2425), and the sixth curved surface (2426) are smaller than the friction coefficients of the third mounting surface (2113) and the sixth mounting surface (2116), the first wearable audio output device (1001) or the second wearable audio output device (1002) can be pulled out more smoothly from the case (100). In addition, since the coefficients of friction of the second curved surface (2412), the third curved surface (2413), the fifth curved surface (2425), and the sixth curved surface (2426) are smaller than the coefficients of friction of the third mounting surface (2113) and the sixth mounting surface (2116), it is possible to prevent or reduce damage to the case (100) and one side of the head (1100) of the wearable audio output device (1000) due to contact between one area of ​​the plurality of first recesses (2100) of the case (100) and one side of the head (1100) of the wearable audio output device (1000) drawn out from the case (100).

[0131] FIG. 27 is a cross-sectional view taken along line A-A' of FIG. 1 according to an embodiment of the present invention, illustrating a process in which a first wearable audio output device accommodated in a case is pulled out from the case. FIG. 28 is a perspective view taken along line A-A' of FIG. 1 according to an embodiment of the present invention, illustrating a process in which a first wearable audio output device accommodated in a case is pulled out from the case. FIG. 29 is a plan view illustrating a process in which a first wearable audio output device accommodated in a case is pulled out from the case.

[0132] Referring to FIGS. 27 to 29, the case (100) can be induced to rotate and tilt in a predetermined direction about the longitudinal direction of the wearable audio output device (1000) as the wearable audio output device (1000) is pulled out from the case (100).

[0133] According to one embodiment, when a user applies an external force in a specific direction to at least a part of the wearable audio output device (1000) accommodated in the case (100), the wearable audio output device (1000) can be pulled out from the case (100). For example, referring to FIG. 27, when an external force is applied in a direction including the sixth direction (+z) with at least a part of the first head (1101) exposed to the outside or at least a part of the first grip portion (1201) exposed to the outside as a point of action, the first wearable audio output device (1001) can be moved in the sixth direction (+z). For example, referring to FIG. 28, when the first wearable audio output device (1001) is accommodated in the case (100), and an external force is applied in a direction including the second direction (+x) with at least a part of the first head (1101) exposed to the outside or at least a part of the first grip portion (1201) exposed to the outside as a point of action, the first wearable audio output device (1001) can be tilted and pulled out in the second direction (+x). For example, referring to FIGS. 27 to 29, the first wearable audio output device (1001) moving in the sixth direction (+z) and tilted in the second direction (+x) can be pulled out by rotating a predetermined angle in a third rotational direction (the third rotational direction (r) of FIG. 21) about the line R-R' of FIG. 21 as an axis by the first curved surface (311) included in the first rear guide portion (301), the first inclined surface (411) included in the first front guide portion (401), and the second curved surface (2412) and the third curved surface (2413) included in the first upper guide portion (241).

[0134] In the present disclosure, the withdrawal operations of the first wearable audio output device (1001) are expressed as discrete individual states, but a series of operations in which the first wearable audio output device (1001) is withdrawn from the case (100) may be continuously continued. In addition, the operation of moving in a specific direction, rotating, or tilting as the first wearable audio output device (1001) is withdrawn from the case (100) may occur simultaneously, and each operation illustrated in the present disclosure does not mean that it occurs exclusively.

[0135] In the present disclosure, only a series of operations of the first wearable audio output device (1001) as the first wearable audio output device (1001) is pulled out from the case (1001) has been described, but a series of operations as the second wearable audio output device (1002) is pulled out from the case (100) can also be understood by the same principle. For example, a series of operations in which the first wearable audio output device (1001) rotates as it is pulled out from the case (100) and a series of operations in which the second wearable audio output device (1002) rotates as it is pulled out from the case (100) can be understood as operations that are symmetrical with respect to the line A-A' of FIG. 1.

[0136] In the present disclosure, only the operation in which the wearable audio output device (1000) is withdrawn from the case (100) has been described, but a series of operations of the wearable audio output device (1000) as the wearable audio output device (1000) is received into the case (100) can be understood in the reverse order of a series of operations in which the wearable audio output device (1000) rotates as the wearable audio output device (1000) is withdrawn from the case (100).

[0137] FIG. 30 is a drawing showing at least one first conductive pin arranged on one side of a first receiving portion according to one embodiment. FIG. 31 is a drawing showing a state in which a first conductive connector of a first wearable audio output device is in contact with at least one first conductive pin of a case when the first wearable audio output device is accommodated in a case according to one embodiment.

[0138] Referring to FIGS. 30 and 31, according to one embodiment, a case (100) and a wearable audio output device (1000) accommodated in the case (100) may be electrically connected.

[0139] According to one embodiment, the case (100) may include at least one conductive pin (510). According to one embodiment, the at least one conductive pin (510) may extend from the rear guide portion (300) and be positioned on a mounting portion (500) forming one side of the receiving portion (120).

[0140] For example, at least one first conductive pin (511) may be arranged on one side of the first mounting portion (501). For example, at least one second conductive pin (at least one second conductive pin (512) of FIG. 2) may be arranged on one side of the second mounting portion (the second mounting portion (502) of FIG. 10). For example, at least one first conductive pin (511) may be coupled to at least one first through-hole (at least one first through-hole (521) of FIG. 10) formed in the first mounting portion (501). For example, at least one second conductive pin (at least one second conductive pin (512) of FIG. 2) may be coupled to at least one second through-hole (at least one second through-hole (522) of FIG. 10) formed in the second mounting portion (the second mounting portion (502) of FIG. 10).

[0141] In the present disclosure, at least one conductive pin (510) is described as being disposed on the mounting portion (500), but is not limited thereto, and for example, at least one conductive pin (510) may be disposed on the first recess (2101) and the third recess (2103).

[0142] According to one embodiment, at least one conductive pin (510) may include a member for detecting a seated state of the wearable audio output device (1000). For example, the member for detecting a seated state of the wearable audio output device (1000) may include at least one of a detect pin, a charging pin, a data communication pin, or a ground (GND) pin.

[0143] According to one embodiment, at least one conductive pin (510) may be formed of a shape or material capable of exerting a repulsive force on a conductive connector (1300) of a wearable audio output device (1000). For example, the conductive pin (510) may include a pogo pin or an elastic C-clip.

[0144] According to one embodiment, the wearable audio output device (1000) may include a conductive connector (1300) arranged to be brought into contact with at least one conductive pin (510) of the case (100) when received and seated in the case (100). For example, a first wearable audio output device (1001) may include a first conductive connector (1301). For example, a second wearable audio output device (1002) may include a second conductive connector (1302). In the present disclosure, the conductive connector (1300) is illustrated as forming at least a portion of one end of a grip portion (1200) of the wearable audio output device (1000), but is not limited thereto. For example, the conductive connector (1300) may form a groove into which at least one conductive pin (510) of the case (100) may be accommodated as the wearable audio output device (1000) is accommodated and seated in the case (100).

[0145] According to one embodiment, when the wearable audio output device (1000) is accommodated and seated in the case (100), and the conductive pin (510) of the case (100) and the conductive connector (1300) of the wearable audio output device (1000) come into contact, the case (100) and the wearable audio output device (1000) may be electrically connected. According to one embodiment, when the case (100) and the wearable audio output device (1000) are electrically connected, the battery (not shown) of the wearable audio output device (1000) may be charged.

[0146] FIG. 32 is a perspective view of an electronic device with the case cover open while housing a wearable audio output device according to one embodiment. FIG. 33 is a front view of an electronic device with the case cover open while housing a wearable audio output device according to one embodiment.

[0147] Referring to FIGS. 32 and 33, a wearable audio output device (1000) is accommodated in a case (100) according to an embodiment, and the case (100) and the wearable audio output device (1000) are electrically connected, so that light output from at least one light emitting module disposed in the case (100) and at least one light emitting module disposed in the wearable audio output device (1000) can be recognized from the outside of the case (100). For example, the light emitting module may include a light source including at least one of a light emitting diode (LED), an infrared (IR), or a xenon lamp.

[0148] According to one embodiment, the case (100) may include at least one light emitting module disposed on one side of the housing (110). For example, the at least one light emitting module disposed on one side of the housing (110) may include a light source including at least one of a light emitting diode (LED), an infrared (IR), or a xenon lamp. For example, the at least one light emitting module disposed on one side of the housing (110) may include three LEDs. For example, the three LEDs may each output light of a first color (e.g., red), a second color (e.g., yellow), and a third color (e.g., green).

[0149] According to one embodiment, the housing (110) may include a first light-transmitting region (600). For example, the first light-transmitting region (600) may be formed to penetrate at least a portion of the housing (110). According to one embodiment, at least one light-emitting module may be arranged in the first light-transmitting region (600) of the housing (110). Light output from the at least one light-emitting module may be visually visible from the outside of the case (100) through the first light-transmitting region (600) of the housing (110).

[0150] According to one embodiment, the case (100) can visually provide information related to the charging status of the battery of the case (100) or the charging status of the battery of the wearable audio output device (1000) to the user through the color of light output from the light-emitting module through the first light-transmitting area (600) of the housing (110).

[0151] According to one embodiment, the case (100) may select at least one LED among a plurality of LEDs included in the light-emitting module to output light based on the remaining battery level of the case (100). For example, when the remaining battery level of the case (100) is less than a first threshold value, the case (100) may output light to the outside of the case (100) through the light-transmitting area (600) using the first red LED included in the light-emitting module.
