The display member 201 may have a first surface F1 facing in a direction (e.g., −Y direction) in which external light is incident and a second surface F2 facing in a direction (e.g., +Y direction) opposite to the first surface F1. In a state where the user wears the electronic device 200, the second surface F2 of the display member 201 may be disposed to face the user's left or right eye and at least partially transmits the light or image incident through the first surface F1 to the user's left eye or right eye.

The lens frame 202 may be a structure at least partially surrounding the edge of the display member 201 to fix at least a portion of the display members 201 and may be supported or positioned on the user's face while the user wears the wearable electronic device 200. For example, the lens frame 202 may position at least one of the display members 201 to correspond to the user's eye. In some embodiments, the lens frame 202 may serve as the rim of a normal eyeglass structure. In some embodiments, the lens frame 202 may at least partially include a material, e.g., metal, with good thermal conductivity. The thermally conductive material may include, e.g., a metal material, but is not limited thereto, and any material having good thermal conductivity may be used as a material for manufacturing the lens frame 202 even when it is not a metal material. The lens frame 202 may be a structure substantially exposed to the exterior of the wearable electronic device 200 and may be easily processed or shaped by including not only a metal material having thermal conductivity but also a polymer, such as polycarbonate. In some embodiments, the lens frame 202 may have a closed loop shape surrounding the display member 201.

The lens frame 202 may be formed of a combination of at least two frames. For example, the lens frame 202 may include a first frame 202a and a second frame 202b. As seen in FIG. 2, the first frame 202a may form a frame structure of a portion facing the user's face when the user wears the wearable electronic device 200, and the second frame 202b may form a frame structure of a portion facing in the direction of the user's gaze when the user wears the wearable electronic device 200. However, the specific shapes of the first frame 202a and the second frame 202b and the coupling relationship between these structures may vary, for example as described below in detail with reference to FIG. 6.

The wearable electronic device 200 may include a camera module 251 (e.g., the camera module 180 and/or the sensor module 253 (e.g., the sensor module 176 of FIG. 1) of FIG. 1) disposed on the lens frame 202. The flexible printed circuit board 205 may electrically connect the camera module 251 and/or the sensor module 253 to the circuit board 241 received in the wearing member 203. The camera module 251 may obtain an image of a surrounding object or environment through a first optical hole 221 formed in the lens frame 202. The camera modules 251 and/or first optical holes 221 may be disposed on two opposite sides of the lens frame 202 (e.g., the second frame 202b), e.g., formed in two opposite ends of the lens frame 202 (e.g., the second frame 202b) with respect to the X direction. The processor (e.g., the processor 120 of FIG. 1) of the electronic device 200 may recognize the object or environment based on the image obtained through the camera module 251. In some embodiments, the wearable electronic device 200 (e.g., the processor 120 or the communication module 190 of FIG. 1) may transmit the image obtained through the camera module 251 to an external electronic device (e.g., the electronic device 102 or 104 or server 108 of FIG. 1) and request information regarding the image.

The flexible printed circuit board 205 may extend from the circuit board 241 through the hinge structure 229 to the inside of the lens frame 202 and may be disposed in at least a portion of the inside of the lens frame 202 around the display member 201. For example, the camera module 251 and/or the sensor module 253 may be disposed substantially in the lens frame 202 and may be positioned around the display member 201.

The sensor module 253 may include a proximity sensor and it may be electrically connected to the circuit board 241 through the flexible printed circuit board 205. The sensor module 253 may detect whether the user's body (e.g., finger) approaches the display member 201 or remains close to the display member 201 within a predetermined distance through the second optical hole 223 formed in the second frame 202b. The sensor module 253 and/or the second optical hole 223 may be disposed in the central portion of the lens frame 202, between the camera modules 251, e.g., in the X direction. In some embodiments, the exemplified configuration of the wearable electronic device 200 includes one sensor module 253 (e.g., a proximity sensor) and one second optical hole 223. However, the present invention is not limited thereto. Various numbers and/or positions may exist for the second optical hole 223 and sensor module 253 to more accurately detect the approach or proximity of the user's body.

If the approach of the user's body is detected through the sensor module 253 (e.g., a proximity sensor), the processor (e.g., the processor 120 of FIG. 1) may be configured to perform a designated function. In some embodiments, if approach of the user's body is detected, the processor 120 may store the image obtained through the camera module 251. For example, the processor 120 may execute various functions based on the signal detected through a proximity sensor (e.g., the sensor module 253) according to the operation mode of the wearable electronic device 200. In some embodiments, the sensor module 253 may include a gaze tracking sensor (not shown). For example, the wearable electronic device 200 may track the user's gaze by including a gaze tracking sensor and adjust the position and/or size of the image output through the display module (e.g., the display module 160 of FIG. 1) according to the user's gaze and provided to the user through the display member 201.

The camera module 251 may be replaced with the sensor module 253, or the sensor module 253 may be replaced with the camera module 251. Further, according to an embodiment, more camera modules 251 and/or sensor modules 253 than those of the embodiment shown in the drawings may be included.

The wearable electronic device 200 may include a pair of wearing members 203. The wearing members 203 each may extend from the lens frame 202 and, together with the lens frame 202, may be partially supported or positioned on the user's body (e.g., ears). In some embodiments, the wearing member 203 may be pivotably coupled to the lens frame 202 through a hinge structure 229. While the wearable electronic device 200 is not in use, the user may fold the wearing members 203 to the lens frame 202 for convenient carrying or storage. A portion of the hinge structure 229 may be mounted on the lens frame 202, and another portion may be received or mounted into the wearing member 203. A hinge cover 227 may be mounted on the lens frame 202 to conceal a portion of the hinge structure 229, and another portion of the hinge structure 229 may be received or hidden between the inner case 231 and the outer case 233 to be described below.

According to various embodiments, the wearable electronic device 200 may include various electric components positioned on the wearing member 203, e.g., the circuit board 241, the battery 243, the camera module 251, the display module (e.g., the display module 160 of FIG. 1), and/or the speaker module 245. Various electric components received in the wearing members 203 may be electrically connected through a circuit board (e.g., the circuit board 241, a flexible printed circuit board (e.g., the flexible printed circuit board 205), conductive cables or connectors). In some embodiments, at least one integrated circuit chip may be mounted on the circuit board 241. Circuit devices, such as the processor 120, communication module 190, power management module 188, or memory 130 of FIG. 1, may be provided in an integrated circuit chip 241a.

The wearing member 203 may include the inner case 231 and the outer case 233. The inner case 231 may be, e.g., a case configured to directly contact the user's body, and may be formed of a material having low thermal conductivity, e.g., a synthetic resin. The outer case 233 may include, e.g., a material (e.g., a metal) capable of at least partially transferring heat and may be coupled to the inner case 231 to face each other. In an embodiment, the circuit board 241 or the speaker module 245 may be received in a space separated from the battery 243 in the wearing member 203. In the illustrated embodiment, the inner case 231 may include a first case 231a including the circuit board 241 or the speaker module 245 and a second case 231b receiving the battery 243, and the outer case 233 may include a third case 233a coupled to face the first case 231a and a fourth case 233b coupled to face the second case 231b. For example, the first case 231a and the third case 233a may be coupled (hereinafter, ‘first case portions 231a and 233a’) to receive the circuit board 241 or the speaker module 245, and the second case 231b and the fourth case 233b may be coupled (hereinafter, ‘second case portions 231b and 233b’) to receive the battery 343.

The first case portions 231a and 233a may be rotatably coupled to the lens frame 202 through the hinge structure 229, and the second case portions 231b and 233b may be connected or mounted to the ends of the first case portions 231a and 233a through the connecting member 235. In some embodiments, a portion of the connecting member 235 in contact with the user's body may be formed of a material having low thermal conductivity, e.g., an elastic material, such as silicone, polyurethane, or rubber, and another portion thereof which does not come into contact with the user's body may be formed of a material having high thermal conductivity (e.g., a metal). For example, when heat is generated from the circuit board 241 or the battery 243, the connecting member 235 may block heat transfer to the portion in contact with the user's body while dissipating or discharging heat through the portion not in contact with the user's body. In some embodiments, a portion of the connecting member 235 configured to come into contact with the user's body may be interpreted as a portion of the inner case 231, and a portion of the connecting member 235 that does not come into contact with the user's body may be interpreted as a portion of the outer case 233.

FIG. 3 is a perspective view illustrating an internal configuration of a display member and a wearing member of a wearable electronic device according to various embodiments of the disclosure. FIG. 4 is a cross-sectional view taken along direction A-A of FIG. 3. FIG. 5 is an enlarged cross-sectional view of portion B of FIG. 4. FIGS. 4 and FIG. 5 may schematically show a position of a reinforcing member 300 disposed in the wearable electronic device 200.

Referring to FIGS. 3 to 5, the wearable electronic device 200 may further include a reinforcing member 300 disposed in the internal space of the lens frame and formed to have a higher rigidity than the lens frame.

The reinforcing member 300 may be a component provided to increase front surface rigidity of the wearable electronic device 200. As shown in FIGS. 3 and 4, when the wearable electronic device 200 opens the wearing members 203, the lens frame 202 may be disposed on the front surface of the wearable electronic device 200. Accordingly, the ‘front surface’ of the wearable electronic device 200 may mean the lens frame 202. As the reinforcing member 300 is disposed, the rigidity of the lens frame 202 may increase, so that warpage may be reduced as compared to other portions of the wearable electronic device 200 in which the reinforcing member 300 is not provided. According to various embodiments, the reinforcing member 300 may be disposed in a portion adjacent to the connecting structure of the lens frame 202 and the wearing member 203 among various portions of the lens frame 202. Here, the ‘portion adjacent to the connecting structure of the lens frame 202 and the wearing member 203’ may mean the upper structure 202-1 of the upper structure 202-1 and the lower structure 202-2 of the lens frame 202. According to an embodiment, the reinforcing member 300 may be disposed in a portion adjacent to the portion in which the camera module 251 and/or the sensor module 253 is disposed in the lens frame 202. As the reinforcing member 300 is disposed in the portion adjacent to the portion in which the camera module 251 and/or the sensor module 253 is disposed, the rigidity of the lens frame 202 of that portion may be increased, and accordingly, the warpage of the lens frame 202 in the portion where the camera module 251 and/or the sensor module 253 is disposed may be reduced, increasing the accuracy of recognition of the space or object using the camera module 251 and/or the sensor module 253. In some embodiments, as shown in FIG. 3, the reinforcing member 300 may be formed to extend along the display members 201 disposed on the left eye and right eye to at least partially surround the left and right display members 201, respectively. Further, in some embodiments, the reinforcing member 300 may have a left/right symmetrical structure with respect to the central portion of the reinforcing member 300.

Referring to FIGS. 4 and 5, the reinforcing member 300 may have a plate shape with a bent portion as viewed in cross-sectional view. For example, the reinforcing member 300 may be formed to have an inverted-‘L’ or ‘L’ shape cross section. The reinforcing member 300 may include a portion (first portion) extending along the length direction (e.g., the +y or −y-axis direction of FIG. 2) and a portion (second portion) extending along the height direction (e.g., z direction of FIG. 2) of the electronic device 200. Length direction may be the length direction of the wearing members 203 when the wearing members 203 of the wearable electronic device 200 are opened, and height direction may be the height direction of the display members 201 of the wearable electronic device.

The reinforcing member 300 may be formed in a position adjacent to the lens frame 202. At least a portion of the reinforcing member 300 may be disposed to overlap the flexible printed circuit board 205 disposed on the lens frame 202.

The shape and dispositional relationship of the reinforcing member 300 are described below in more detail below with reference to FIG. 6.

FIG. 6 is a view illustrating a rigidity securing structure of a wearable electronic device according to various embodiments of the disclosure.

FIG. 6 depicts a conceptual view for a dispositional relationship between the lens frame 202 of the wearable electronic device 200, the flexible printed circuit board 205 and reinforcing member 300 disposed in the lens frame 202.

The lens frame 202 may include a first frame 202a and a second frame 202b surrounding at least a portion of the display members 201 and coupled to the first frame 202a to form an internal space of the electronic device. According to an embodiment, the first frame 202a may be disposed to face the user's face. The second frame 202b may include a second frame 202b coupled to the first frame 202a to face each other. For example, in a state in which the user wears the wearable electronic device 200, the first frame 202a may be disposed towards the user's face, and the second frame 202b may be disposed in a direction opposite to the first frame 202a, e.g., in the direction where the user views. In an embodiment, the display members 201 may be disposed on the lens frame 202 with the first surface F1 and the second surface F2 exposed to the external environment. According to an embodiment, at least a portion of the edge of the display members 201 may be positioned on the seating portion 202b′ of the second frame 202b. The specific shape and connecting structure of the first frame 202a and the second frame 202b may be varied depending on embodiments. Although not shown in the drawings, at least a portion of the edge of the display members 201 may be positioned between the first frame 202a and the second frame 202b. For example, the first frame 202a and the second frame 202b are coupled to face each other, fastening or fixing the edge of at least one of the display members 201.

The first frame 202a may include a 1-1th frame 202a-1 forming the outermost frame of the wearable electronic device, which is farthest from the display members 201 and a 1-2th frame 202a-2 bent from the 1-1th frame 202a-1 to face the user's face when worn by the user. The 1-2th frame 202a-2 may be bent substantially perpendicular to the 1-1th frame 202a-1, but is not limited thereto. The 1-1th frame 202a-1 and the 1-2th frame 202a-2 may be integrally formed by including a polymer, such as polycarbonate, which is easy to process and shape.

The second frame 202b may include a 2-1th frame 202b-1 having a seating portion 202b′ where the display members 201 are drawn in to be seated and a 2-2th frame 202b-2 bent from the 2-1th frame 202b-1 to face the user's gaze direction when worn by the user. The 2-2th frame 202b-2 may be bent substantially perpendicular to the 2-1th frame 202b-1, but is not limited thereto. The 2-1th frame 202b-1 and the 2-2th frame 202b-2 may be integrally formed by including a polymer, such as polycarbonate, which is easy to process and shape. The respective ends of the first frame 202a and the second frame 202b may be coupled to each other to form the overall appearance of the wearable electronic device.

A flexible printed circuit board 205 may be disposed in the internal space between the first frame 202a and the second frame 202b. The flexible printed circuit board 205 may be a component for electrical connection between at least one electronic component disposed in the lens frame 202 and an electronic component disposed in the wearing member 203 or in another position in the lens frame 202. For example, as described above in connection with FIG. 2, the flexible printed circuit board 205 may be a component to electrically connect the camera module 251 and/or the sensor module 253 to the circuit board 241 received in the wearing member 203. In some embodiments, the flexible printed circuit board 205 may be disposed on or over the second frame 202b. In this case, at least a portion of the flexible printed circuit board 205 may be supported from the second frame 202b. In some embodiments, although not shown in the drawings, at least one electronic component may be mounted on the flexible printed circuit board 205.

The wearable electronic device 200 may include a reinforcing member 300 formed to have higher rigidity than the lens frame 202 and including a first portion 300a disposed between the flexible printed circuit board 205 and the first frame 202a and a second portion 300b bent from the first portion 300a at a predetermined angle. In some embodiments, the reinforcing member 300 may include carbon fiber reinforced plastics (CFRP). For example, when the rigidity of the lens frame 202 including polycarbonate is 2 GPa, the rigidity of the reinforcing member 300 may be measured as 42 GPa to 76 GPa. For example, if the wearable electronic device 200 in which the specific gravity of the display members 201 is 2.4, and the specific gravity of the lens frame 202 is 1.2 adds a reinforcing member 300 whose specific gravity is 1.2 to 1.55, it is possible to provide a wearable electronic device 200 having higher rigidity than the lens frame 202 including only polycarbonate, with an increase in weight minimized.

The first portion 300a of the reinforcing member 300 may be formed to at least partially face the 1-1th frame 202a-1, and the second portion 300b of the reinforcing member 300 may be formed to at least partially face the 1-2th frame 202a-2. As shown in FIG. 6, the first portion 300a of the reinforcing member 300, along with the 1-1th frame 202a-1, may extend toward the wearing member 203 of the wearable electronic device 200, and the second portion 300b of the reinforcing member 300 may extend toward the display members 201 while contacting the 1-2th frame 202a-2. As the first portion 300a of the reinforcing member 300 contacts the 1-1th frame 202a-1, and the second portion 300b contacts the 1-2th frame 202a-2, the rigidity of the lens frame 202 may be enhanced. According to an embodiment, the reinforcing member 300 may be shaped to be attached to the first frame 202a.

Further, as shown in the FIG. 6, the second portion 300b, along with the 1-2th frame 202a-2, may extend toward the display members 201, and its end may contact a portion of the 2-1th frame 202b-1. Accordingly, an end of the second portion 300b may contact the first frame 202a, and the other end may contact the second frame 202b to be supported from the reinforcing member of the lens frame 202, further enhancing the rigidity of the lens frame 202.

As shown in FIG. 6, the reinforcing member 300 may directly contact the flexible printed circuit board 205, but is not necessarily limited thereto. As described above in connection with FIG. 5, the reinforcing member 300 may be spaced apart from the flexible printed circuit board by a predetermined gap. According to an embodiment, when at least one electronic component is disposed on the flexible printed circuit board, at least a portion of the reinforcing member 300 may be stacked with the at least one electronic component. For example, the electronic component that may be disposed on the flexible printed circuit board may correspond to at least one of the camera module 251, the sensor module 253, or a receiver.

In relation to a method for manufacturing a rigidity securing structure shown in FIG. 6, according to an embodiment, the second frame 202b coupled with the display members 201 may be attached to the first frame 202a, with the first frame 202a and the reinforcing member 300 attached to each other.

FIG. 7A is a view illustrating an example in which a user wears a wearable electronic device. FIG. 7B is a view illustrating an embodiment in which a wearing member of a wearable electronic device hits a user's face portion and an embodiment in which the wearing member of the wearable electronic device does not hit the user's face portion. FIGS. 8A to 8C are views illustrating various embodiments of tension generated in a wearing member of a wearable electronic device. FIG. 8A is a view illustrating a wearing member before a user wears a wearable electronic device. FIG. 8B is a view illustrating an example in which wearing members are opened in directions opposite to the direction toward a user's head with respect to a hinge structure when the user wears a wearable electronic device. FIG. 8C is a view illustrating an example in which flexible portions of wearing members are opened in directions opposite to the direction toward a user's head when the user wears a wearable electronic device.

Referring to FIGS. 7a and 7b , when the user wears the wearable electronic device 200 on the head H, the lens frame 202 may be positioned on the user's face F, and the wearing members 203 may be hung on the user's ears E. In the rigidity-reinforced wearable electronic device in the embodiment described above in connection with FIG. 6, the warpage of the lens frame 202 may be reduced, so that a portion of the wearing members 203 may contact the face F when the user wears the wearable electronic device 200, causing inconvenience in use. Accordingly, a method for enhancing the wearing comfort of the wearable electronic device 200 may be provided corresponding to the enhanced rigidity of the lens frame 202. For example, as in the embodiment shown in FIGS. 8A to 8C, the wearable electronic device 200 may apply a tension structure to the hinge structure 229 (refer to FIG. 8(b )) and apply a flexible structure (or a flexible portion) to the wearing member 203 (refer to FIG. 8(c )), enhancing the wearing comfort of the wearable electronic device 200.

FIG. 9 is a view illustrating a rigid portion and a flexible portion of a wearing member according to various embodiments of the disclosure. FIG. 10 is an enlarged view of a flexible portion of a wearing member according to various embodiments of the disclosure.

There may be provided a method for reducing the concentration of the weight of the wearable electronic device 200 to the lens frame 202 or on the user's face. Referring back to FIG. 2 together with FIGS. 9 and 10, the positions of the electric components may be varied in the wearing members 203 to evenly distribute the weight of the wearable electronic device 200 with the wearable electronic device 200 worn. For example, in the wearing member 203, the circuit board 241 may be disposed adjacent to the lens frame 202, and the electric component (e.g., the battery 243) which is heavier than the circuit board 241 may be disposed farther from the lens frame 202 than the circuit board 241. Accordingly, it is possible to mitigate the concentration of the weight of the wearable electronic device 200 to the lens frame 202 or on the user's face. The speaker module 245 may be disposed in the wearing member 203 between the circuit board 241 and the battery 243, and may be positioned close to the user's ear while the user wears the wearable electronic device 200.

The wearing member 203 may include a rigid portion having relatively low bendability and a flexible portion having relatively high bendability. In some embodiments, the wearing member 203 may be formed by combining at least one rigid portion and at least one flexible portion. For example, the wearing member 203 may include a first rigid portion S1 formed adjacent to the lens frame 202, a flexible portion S2 provided to reduce pressure on the side of the face when worn by the user, and a second rigid portion S3 positioned at the end of the wearing member 203. Here, the first rigid portion S1 may correspond to a portion in which the circuit board 241 and the speaker module 245 are disposed. The second rigid portion S3 may correspond to a portion in which the battery 243 is disposed. The first rigid portion S1 and the second rigid portion S3 may be relatively less bendable because their appearance is formed by the inner/outer cases 231 and 233 as described above in FIG. 2. The flexible portion S2 is a portion where the connecting member 235 is disposed, and may be formed of an elastic material, such as silicone, polyurethane, or rubber, and be provided between the first rigid portion S1 and the second rigid portion S3. A wire 246 for electrically connecting the circuit board 241 disposed on the first rigid portion S1 and the battery 243 disposed on the second rigid portion S3 may be provided inside the connecting member 235. The electronic components mounted in the internal space of the cases 231 and 233 of the first rigid portion S1 and the second rigid portion S3 may be electrically connected by the wire 246, while the cases 231 and 233 of the first rigid portion Si and the second rigid portion S3 each may be bonded and connected to the connecting member 235 of the flexible portion S2. It is possible to provide a wearable electronic device 200 that is warpable as in the embodiment shown in FIG. 8(c ) by using a combined structure of the rigid portion and the flexible portion of the wearing member 203.

FIG. 11 is a perspective view illustrating a wearable electronic device including a hinge structure according to various embodiments of the disclosure. FIG. 12 is a perspective view illustrating a hinge structure according to various embodiments of the disclosure. FIG. 13 is a cross-sectional view illustrating a hinge structure according to various embodiments of the disclosure. FIG. 13 may show a cross-section taken along direction A-A′ of the hinge structure of FIG. 12.

The wearable electronic device 200 may further include a hinge structure 229 disposed between the lens frame 202 and the wearing member 203 and provided to fold the wearing member 203 about the lens frame 202. As described above in connection with FIG. 2, the wearing member 203 may be pivotably coupled to the lens frame 202 through a hinge structure 229. While the wearable electronic device 200 is not in use, the user may fold the wearing members 203 to the lens frame 202 for convenient carrying or storage.

The hinge structure 229 may be provided to fold the wearing member 203 about the lens frame 202 and may also be formed to rotate about the lens frame 202 in the direction opposite to the folding direction.

Referring to FIGS. 12 and 13, the hinge structure 229 may include a first hinge portion 229a connected with the lens frame 202 and a second hinge portion 229b axis-coupled with the first hinge portion 229a and connected with the wearing member 203. The hinge structure 229 may further include a restoring member 292c having a portion connected to the first hinge portion 229a and another portion extending towards the second hinge portion 229b. The restoring member 229c may be formed of, e.g., a leaf spring, and may be formed to cover at least a portion of an outer surface of the first hinge portion 229a and an outer surface of the second hinge portion 229b. A portion of the restoring member 229c may be received and fixed in a recess formed in the outer surface of the first hinge portion 229a, and another portion may be received in a recess 229d formed in the outer surface of the second hinge portion 229b.

In an example of rotating about the lens frame 202 in the direction opposite to the folding direction of the wearing member 203, in the initial state where the first hinge portion 229a and the second hinge portion 229b are parallel to each other, the second hinge portion 229b and the restoring member 229c may be rotated by a predetermined angle (e.g., 5°)and be then restored to the initial state due to the elastic restoring force of the restoring member 229c. In other words, there may be a structure (tension structure) where the wearing member 203 is rotated about the lens frame 202 by a predetermined angle in the direction opposite to the folding direction, but is restored to the original position by the restoring member 229c.

It is possible to provide a wearable electronic device 200 that is warpable as in the embodiment shown in FIG. 8(b) by using such a hinge structure 229.

It is possible to secure high rigidity of the frame for increasing the accuracy of sensing of the sensor positioned on the front surface of the wearable electronic device 200. Furthermore, it is possible to minimize the concentration of weight on the front portion of the wearable electronic device 200 by applying a lightweight material (e.g., carbon fiber reinforced plastic) as a component for securing high rigidity.

In some embodiments, to minimize the issue that the wearing member hits the user's face when wearing due to securing the rigidity of the front surface of the wearable electronic device 200, the hinge structure 229 is provided for rotating the wearing member about the lens frame in the direction opposite to the folding direction by predetermined tension, thereby enhancing wearing comfort.

In some embodiments, to minimize the issue that the wearing member hits the user's face when wearing due to securing the rigidity of the front surface of the wearable electronic device 200, wearing members 203 having a flexible portion between rigid portions is applied, so that the wearing members are maximally opened while wearing and, after wearing, tightly contact the user's face, thereby enhancing wearing comfort.
