Title: Electronic device including waterproof structure

Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2021/018897, filed on Dec. 13, 2021, which is based on and claims the benefit of a Korean patent application number 10-2021-0003527, filed on Jan. 11, 2021, in the Korean Intellectual Property Office, and of a Korean patent application number 10-2021-0043604, filed on Apr. 2, 2021, in the Korean Intellectual Property Office the disclosure of which is incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     The disclosure relates to an electronic device including a waterproof structure. 
     BACKGROUND ART 
     An electronic device may include at least one vent hole for allowing air pressure inside the electronic device and air pressure outside the electronic device to remain the same. For example, air may flow through the vent hole so that the air pressure inside the electronic device and the air pressure outside the electronic device may remain substantially the same. Accordingly, low performance and/or malfunctions of various electronic components due to an air-pressure difference may be reduced. In addition, the electronic device may include a waterproof structure to prevent introduction of liquid into the electronic device through the vent hole. 
     The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. 
     DISCLOSURE 
     Technical Problem 
     The electronic device may be configured such that air flows between the inside of the housing and the outside of the housing through the vent hole exposed outside the housing, and the waterproof structure may be provided on one side of the vent hole. Liquid outside the electronic device may be introduced into the vent hole. In this case, the pressure of the liquid delivered to the waterproof structure may be reduced when the path of the vent hole is formed to be long and complicated. However, when the formation of the long and complicated path of the vent hole is restricted due to a limitation in design, the pressure of the liquid delivered to the waterproof structure may be high. Therefore, the liquid may pass through the waterproof structure, and thus a waterproof function may be deteriorated. 
     Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device including a waterproof structure for reducing the pressure of liquid introduced through a vent hole. 
     Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments. 
     Technical Solution 
     In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes a front plate, a back plate that faces the front plate, a side member that surrounds an inner space between the front plate and the back plate and includes a frame that forms a side surface of the electronic device and a plate that extends from the frame toward the inner space, and a blocking member located in the inner space and disposed on the plate to cover a partial area of the plate connected with the outside of the electronic device. The blocking member includes a membrane including a first surface and a second surface that faces away from the first surface and a cover member that is disposed between the second surface of the membrane and the plate and that has a through-hole formed in at least a portion thereof. The through-hole fluidly communicates with the outside of the electronic device through the partial area of the plate. 
     In accordance with another aspect of the disclosure, a blocking member is provided. The blocking member includes a membrane including a first surface and a second surface that faces away from the first surface, a cover member that is attached to the second surface of the membrane and that has a through-hole formed in at least a portion thereof, the cover member including a third surface that faces the second surface and a fourth surface that faces away from the third surface, and a first adhesive member that is disposed between the second surface and the third surface and that attaches the membrane and the cover member to each other, the first adhesive member having a first opening, at least a portion of which overlaps the through-hole. The membrane is formed of an air-permeable material, and the cover member is formed of a non-breathable material. 
     Advantageous Effects 
     The electronic device according to the various embodiments of the disclosure may reduce the pressure of liquid delivered to the membrane of the waterproof structure, thereby providing stable waterproofing performance. 
     In addition, the disclosure may provide various effects that are directly or indirectly recognized.

     Referring to  FIGS. 1 and 2 , an electronic device  100  according to an embodiment may include a housing  110  that forms the exterior of the electronic device  100 . For example, the housing  110  may include a first surface (or, a front surface)  110 A, a second surface (or, a rear surface)  110 B, and a third surface (or, a side surface)  110 C that surrounds a space between the first surface  110 A and the second surface  110 B. 
     In various embodiments, the housing  110  may refer to a structure that forms some of the first surface  110 A, the second surface  110 B, and the third surface  110 C. 
     In an embodiment, the first surface  110 A may be formed by a front plate  102 , at least a portion of which is substantially transparent (e.g., a glass plate including various coating layers, or a polymer plate). The second surface  110 B may be formed by a back plate  111  that is substantially opaque. For example, the back plate  111  may be formed of coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two thereof. The third surface  110 C may be formed by a side bezel structure (or, a side member)  118  that is coupled with the front plate  102  and the back plate  111  and that contains metal and/or polymer. 
     In various embodiments, the back plate  111  and the side bezel structure  118  may be integrally formed with each other and may contain the same material (e.g., a metallic material such as aluminum). 
     In the illustrated embodiment, the front plate  102  may include two first areas  110 D that curvedly and seamlessly extend from partial areas of the first surface  110 A toward the back plate  111 . The first areas  110 D may be located at opposite long edges of the front plate  102 . 
     In the illustrated embodiment, the back plate  111  may include two second areas  110 E that curvedly and seamlessly extend from partial areas of the second surface  110 B toward the front plate  102 . The second areas  110 E may be located at opposite long edges of the back plate  111 . 
     In various embodiments, the front plate  102  (or, the back plate  111 ) may include only one of the first areas  110 D (or, the second areas  110 E). Furthermore, in another embodiment, the front plate  102  (or, the back plate  111 ) may not include a part of the first areas  110 D (or, the second areas  110 E). 
     In an embodiment, when viewed from a side of the electronic device  100 , the side bezel structure  118  may have a first thickness (or, width) at sides (e.g., short sides) not including the first areas  110 D or the second areas  110 E and may have a second thickness at sides (e.g., long sides) including the first areas  110 D or the second areas  110 E, the second thickness being smaller than the first thickness. 
     In an embodiment, the electronic device  100  may include at least one of a display  101 , audio modules  103 ,  104 , and  107  (e.g., an audio module  470  of  FIG. 21 ), a sensor module (not illustrated) (e.g., a sensor module  476  of  FIG. 21 ), camera modules  105   112 , and  113  (e.g., a camera module  480  of  FIG. 21 ), key input devices  117  (e.g., an input device  450  of  FIG. 21 ), a light emitting element (not illustrated), or a connector hole  108  (e.g., a connecting terminal  478  of  FIG. 21 ). In another embodiment, the electronic device  100  may not include at least one component (e.g., the key input devices  117  or the light emitting element (not illustrated)) among the aforementioned components, or may additionally include other component(s). 
     In an embodiment, the display  101  may be visually exposed through most of the front plate  102 . For example, at least a portion of the display  101  may be visually exposed through the front plate  102  that includes the first surface  110 A and the first areas  110 D of the third surface  110 C. The display  101  may be disposed on the rear surface of the front plate  102 . 
     In an embodiment, the periphery of the display  101  may be formed to be substantially the same as the shape of the adjacent outside edge of the front plate  102 . In another embodiment, the gap between the outside edge of the display  101  and the outside edge of the front plate  102  may be substantially constant to expand the area by which the display  101  is visually exposed. 
     In an embodiment, a surface of the housing  110  (or, the front plate  102 ) may include a screen display area that is formed as the display  101  is visually exposed. For example, the screen display area may include the first surface  110 A and the first areas  110 D of the side surface.

For example, the first sidewall  141   a  may form the side surface facing the +y-axis direction, and the second sidewall  141   b  may form the side surface facing the −y-axis direction. For example, the third sidewall  141   c  may form the side surface facing the +x-axis direction, and the fourth sidewall  141   d  may form the side surface facing the −x-axis direction. 
     In an embodiment, the first sidewall  141   a  and the second sidewall  141   b  may be disposed to face each other and may extend in the x-axis direction. The third sidewall  141   c  and the fourth sidewall  141   d  may be disposed to face each other and may extend in the y-axis direction. The frame  141  may be configured such that the plurality of sidewalls  141   a ,  141   b ,  141   c , and  141   d  are connected or integrated with one another. For example, the third sidewall  141   c  may connect one end portion (e.g., the end portion facing the +x-axis direction) of the first sidewall  141   a  and one end portion (e.g., the end portion facing the +x-axis direction) of the second sidewall  141   b , and the fourth sidewall  141   d  may connect an opposite end portion (e.g., the end portion facing the −x-axis direction) of the first sidewall  141   a  and an opposite end portion (e.g., the end portion facing the −x-axis direction) of the second sidewall  141   b.    
     In an embodiment, the plate  142  may be disposed inside the frame  141  so as to be surrounded by the frame  141 . The plate  142  may be connected with the frame  141 , or may be integrally formed with the frame  141 . The plate  142  may be formed of a metallic material and/or a nonmetallic (e.g., polymer) material. 
     In an embodiment, the plate  142  may support other components included in the electronic device  100 . For example, at least one of the display  130 , the printed circuit board  150 , the rear case  160 , or the battery  170  may be disposed on the plate  142 . For example, the display  130  may be coupled to one surface (e.g., the surface facing the +z-axis direction) of the plate  142 , and the printed circuit board  150  may be coupled to a surface (e.g., the surface facing the −z-axis direction) of the plate  142  that faces away from the one surface. 
     In an embodiment, the rear case  160  may be disposed between the back plate  180  and the plate  142 . The rear case  160  may be coupled to the side member  140  so as to overlap at least a portion of the printed circuit board  150 . For example, the rear case  160  may face the plate  142  with the printed circuit board  150  therebetween. 
     In an embodiment, a processor (e.g., a processor  420  of  FIG. 21 ), a memory (e.g., a memory  430  of  FIG. 21 ), and/or an interface (e.g., an interface  477  of  FIG. 21 ) may be mounted on the printed circuit board  150 . The processor may include, for example, one or more of a central processing unit, an application processor, a graphic processing unit, an image signal processor, a sensor hub processor, or a communication processor.

     In an embodiment, the battery  170  (e.g., a battery  489  of  FIG. 21 ) may supply power to at least one component of the electronic device  100 . For example, the battery  170  may include a primary cell that is not rechargeable, a secondary cell that is rechargeable, or a fuel cell. At least a portion of the battery  170  may be disposed on substantially the same plane as the printed circuit board  150 . The battery  170  may be integrally disposed inside the electronic device  100 , or may be disposed so as to be detachable from the electronic device  100 . 
     In an embodiment, the antenna (not illustrated) (e.g., an antenna module  497  of  FIG. 21 ) may be disposed between the back plate  180  and the battery  170 . The antenna (not illustrated) may include, for example, a near field communication (NFC) antenna, a wireless charging antenna, and/or a magnetic secure transmission (MST) antenna. For example, the antenna (not illustrated) may perform short-range communication with an external device, or may wirelessly transmit and receive power required for charging. 
     In an embodiment, the first camera module  105  (e.g., a front camera) may be disposed on at least a portion (e.g., the plate  142 ) of the side member  140  such that a lens receives external light through a partial area of the front plate  120  (e.g., the front surface  110 A of  FIG. 1 ). For example, the lens of the first camera module  105  may be visually exposed through a partial area (e.g., a camera area  137 ) of the front plate  120 . 
     In an embodiment, the second camera module  112  (e.g., a rear camera) may be disposed in at least a portion of an inner space formed in the housing (e.g., the housing  110  of  FIGS. 1 and 2 ) of the electronic device  100  and may be electrically connected to the printed circuit board  150  through a connecting member (e.g., a connector). In an embodiment, the second camera module  112  may be disposed on the printed circuit board  150  such that a lens receives external light through a camera area  184  of the back plate  180  (e.g., the rear surface  110 B of  FIG. 2 ) of the electronic device  100 . For example, the lens of the second camera module  112  may be visually exposed through the camera area  184 . 
     In an embodiment, the camera area  184  may be formed in a surface (e.g., the rear surface  110 B of  FIG. 2 ) of the back plate  180 . In an embodiment, the camera area  184  may be formed to be at least partially transparent such that external light is incident on the lens of the second camera module  112 . In an embodiment, at least a portion of the camera area  184  may protrude to a predetermined height from the surface of the back plate  180 . However, without being necessarily limited thereto, the camera area  184  may form substantially the same plane as the surface of the back plate  180 .

       FIG. 6  may be a sectional view of the electronic device  100  taken along line A-A′ illustrated in  FIG. 5  according to an embodiment of the disclosure. 
     Referring to  FIGS. 4A, 4B, 5, and 6 , the electronic device  100  according to an embodiment may include the front plate  120  (e.g., the front plate  120  of  FIG. 3 ), the display  130  (e.g., the display  130  of  FIG. 3 ), the side member  140  (e.g., the side member  140  of  FIG. 3 ), the printed circuit board  150  (e.g., the printed circuit board  150  of  FIG. 3 ), the rear case  160  (e.g., the rear case  160  of  FIG. 3 ), the back plate  180  (e.g., the back plate  180  of  FIG. 3 ), adhesive tapes  191  and  192 , and a blocking member  200  (hereinafter, referred to as the waterproof structure  200 ). 
     Some of the components of the electronic device  100  illustrated in  FIGS. 4A to 6  may be identical or similar to the components of the electronic device  100  illustrated in  FIGS. 1 to 3 , and therefore repetitive descriptions will hereinafter be omitted. 
     In an embodiment, the exterior of the electronic device  100  may be formed by a coupling structure of the front plate  120 , the side member  140 , and the back plate  180 . For example, the housing  110  (e.g., the housing  110  of  FIGS. 1 and 2 ) of the electronic device  100  may be formed by a coupling of the front plate  120 , the side member  140 , and the back plate  180 . 
     In an embodiment, the front plate  120  and the back plate  180  may be disposed to face each other, and a portion (e.g., the frame  141 ) of the side member  140  may surround the space between the front plate  120  and the back plate  180  to form an inner space S of the electronic device  100  (or, the housing  110 ). For example, the inner space S may be understood as a predetermined space that is formed in the housing  110  and in which other components (e.g., the display  130 , the printed circuit board  150 , the rear case  160 , and/or the waterproof structure  200 ) of the electronic device  100  are accommodated. 
     In an embodiment, the front plate  120  and the back plate  180  may be coupled with the side member  140 . For example, the front plate  120  may be coupled to the plate  142  through the first adhesive tape  191  in the state of being attached to the display  130 . The back plate  180  may be attached to the plate  142  through the second adhesive tape  192 . 
     In an embodiment, at least a portion (e.g., the plate  142 ) of the side member  140  may be located in the inner space S between the front plate  120  and the back plate  180 . In an embodiment, the display  130  may be disposed between the front plate  120  and the plate  142 , and the rear case  160  and/or the printed circuit board  150  may be disposed between the back plate  180  and the plate  142 . For example, the display  130 , the printed circuit board  150 , and the rear case  160  may be supported by the plate  142  of the side member  140  and may be located in the inner space S. 
     In an embodiment, the display  130  may be disposed on the rear surface (e.g., the surface facing the −z-axis direction) of the front plate  120 . For example, the display  130  may be disposed on the rear surface of the front plate  120  so as to be located in the inner space S of the electronic device  100 . The display  130  may be visually exposed through the front plate  120  in the direction toward the front side of the electronic device  100  (e.g., in the +z-axis direction). 
     In an embodiment, the display  130  may be attached to the plate  142  of the side member  140  in the state of being coupled with the front plate  120 . For example, the front plate  120  may be attached to one surface (e.g., the surface facing the +z-axis direction) of the display  130 , and an opposite surface (e.g., the surface facing the −z-axis direction) of the display  130  may be attached to the plate  142 . The display  130  may be attached to the plate  142  through the adhesive tapes  191  and  192  disposed between the plate  142  and the display  130 . 
     In various embodiments, the display  130  and the front plate  120  may be coupled through various adhesive members (not illustrated) to form a display assembly. The display assembly may be coupled to the side member  140  through the adhesive tapes  191  and  192 . For example, it may be understood that  FIGS. 4B and 5  illustrate the state in which the display assembly (e.g., the front plate  120  and the display  130 ) is not attached to the side member  140 . 
     In an embodiment, the side member  140  may include the frame  141  surrounding the inner space S between the front plate  120  and the back plate  180  and the plate  142  extending from the frame  141  toward the inner space S. For example, the plate  142  may extend from the inside of the frame  141  such that at least a portion of the plate  142  is located between the front plate  120  and the back plate  180 . 
     In an embodiment, the plate  142  may support the display  130 , the printed circuit board  150 , the rear case  160 , and the back plate  180 . For example, the display  130  and the front plate  120  may be disposed on one surface (e.g., the surface facing the +z-axis direction) of the plate  142 . The printed circuit board  150 , the rear case  160 , and the back plate  180  may be disposed on an opposite surface (e.g., the surface facing the −z-axis direction) of the plate  142 . 
     In an embodiment, the frame  141  may surround the plate  142 . For example, the frame  141  may include a plurality of sidewalls extending along the periphery of the plate  142  to surround the plate  142 . 
     In an embodiment, the frame  141  may include the first sidewall  141   a , and the third sidewall  141   c  and the fourth sidewall  141   d  that extend to the first sidewall  141   a . Although not illustrated in  FIGS. 4A, 4B, 5, and 6 , the frame  141  may include the second sidewall (e.g., the second sidewall  141   b  of  FIG. 3 ) that faces the first sidewall  141   a . For example, the third sidewall  141   c  and the fourth sidewall  141   d  may extend from the opposite end portions of the first sidewall  141   a  toward the second sidewall  141   b.    
     In an embodiment, the side member  140  may include a vent hole  143  formed through at least a portion of the side member  140  such that the outside of the electronic device  100  (or, the housing  110 ) and the inner space S of the electronic device  100  (or, the housing  110 ) fluidly communicate with each other. For example, when the outside of the housing  110  and the inner space S fluidly communicate with each other, this may mean that the outside of the housing  110  and the inner space S are partially connected to enable a movement of fluid between the outside of the housing  110  and the inner space S. In various embodiments, the waterproof structure  200  may be disposed on a partial area of the side member  140  to allow for a movement of air through the vent hole  143  but prevent introduction of water into the inner space S. 
     In an embodiment, the vent hole  143  may be formed through the frame  141  and at least a portion of the plate  142 . For example, the vent hole  143  may extend a partial area of the first sidewall  141   a  of the frame  141  to a partial area of the plate  142 . According to the illustrated embodiment, the vent hole  143  may penetrate the first sidewall  141   a . However, this is illustrative, and the position of the vent hole  143  is not limited to that illustrated. According to various embodiments, the vent hole  143  may be formed through the second sidewall  141   b , the third sidewall  141   c , and/or the fourth sidewall  141   d.    
     In an embodiment, the vent hole  143  may include a first opening area  143   a  formed in the frame  141 , a second opening area  143   b  formed in the plate  142 , and a duct connecting the first opening area  143   a  and the second opening area  143   b . For example, the first opening area  143   a  may be formed in the first sidewall  141   a  of the frame  141 , and the duct  143   c  may extend from the first opening area  143   a  toward the second opening area  143   b . For example, the duct  143   c  may extend from the first opening area  143   a  toward the inner space S (e.g., in the −y-axis direction), and at least a portion of the duct  143   c  may be connected with the second opening area  143   b . For example, at least a portion of the duct  143   c  may extend toward the display  130  (e.g., in the +z-axis direction) such that the second opening area  143   b  is open toward the display  130 . In various embodiments, the duct  143   c  may extend from the first sidewall  141   a  of the frame  141  to a partial area of the plate  142 . 
     In an embodiment, as the first opening area  143   a  of the vent hole  143  is formed in the first sidewall  141   a , the first opening area  143   a  of the vent hole  143  may be exposed on an outer surface (e.g., the side surface facing the +y-axis direction) of the electronic device  100 . As the second opening area  143   b  of the vent hole  143  is formed in the plate  142 , the second opening area  143   b  of the vent hole  143  may be located in the inner space S. For example, fluid outside the electronic device  100  may move into the duct  143   c  through the first opening area  143   a . In various embodiments, the first sidewall  141   a  having the first opening area  143   a  formed therein and the plate  142  having the second opening area  143   b  formed therein may be substantially perpendicular to each other, and the duct  143   c  may be formed in a shape in which at least a portion is inclined or bent such that the duct  143   c  penetrates from a partial area of the first sidewall  141   a  to a partial area of the plate  142 . 
     In an embodiment, the second opening area  143   b  may be covered by the waterproof structure  200 . For example, when the front plate  120  or the display  130  of the electronic device  100  is viewed from above, the second opening area  143   b  of the vent hole  143  may overlap the waterproof structure  200 . As illustrated in  FIGS. 4B and 5 , when the plate  142  is viewed from above (e.g., in the +z-axis direction), the second opening area  143   b  may not be visually exposed as the second opening area  143   b  overlaps the waterproof structure  200  and is hidden by the waterproof structure  200 . For example, the second opening area  143   b  and the inner space S may be configured such that a movement of liquid (e.g., water) therebetween is interrupted by the waterproof structure  200 , but air is movable therebetween. 
     In an embodiment, the first opening area  143   a  and the second opening area  143   b  may be defined as areas that form opposite end portions of the vent hole  143  having a predetermined shape. The duct  143   c  may extend to connect the first opening area  143   a  and the second opening area  143   b , and the shape of the vent hole  143  may be substantially determined by the direction and shape in which the duct  143   c  extends. According to various embodiments, the waterproofing effect of the electronic device  100  may be improved depending on the shape and the inclined direction of the duct  143   c . Various embodiments of the shape of the duct  143   c  will be described below with reference to  FIGS. 15 and 16 . 
     The electronic device  100  according to an embodiment may be configured such that air moves from the outside of the electronic device  100  to the inner space S or from the inner space S to the outside of the electronic device  100  through the vent hole  143 . For example, air outside the housing  110  may flow into the duct  143   c  through the first opening area  143   a  and may move into the inner space S through the second opening area  143   b  and the waterproof structure  200 . For example, even though liquid (e.g., water) flows from the outside of the electronic device  100  into the duct  143   c  through the first opening area  143   a , the liquid may fail to pass through the waterproof structure  200  covering the second opening area  143   b , and therefore a movement of the liquid into the inner space S may be interrupted. 
     According to an embodiment, the electronic device  100  may maintain the air pressure outside the electronic device  100  and the air pressure inside the electronic device  100  at the same pressure through the vent hole  143 , thereby reducing defects in various components (e.g., a sensor) of the electronic device  100  due to a difference between the air pressure outside the electronic device  100  and the air pressure inside the electronic device  100 . 
     In an embodiment, the adhesive tapes  191  and  192  may include the first adhesive tape  191  for attaching the display  130  to the side member  140  and the second adhesive tape  192  for attaching the back plate  180  to the side member  140 . In an embodiment, the first adhesive tape  191  and/or the second adhesive tape  192  may contain a waterproof material. For example, the first adhesive tape  191  and/or the second adhesive tape  192  may be a waterproof tape. 
     In an embodiment, the first adhesive tape  191  may be disposed between the plate  142  of the side member  140  and the display  130 . For example, a portion of the first adhesive tape  191  may be disposed between the periphery of the plate  142  and the display  130 . The display  130  may be attached to the plate  142  through the first adhesive tape  191 . The first adhesive tape  191  may partially seal the space between the plate  142  and the display  130 . 
     In an embodiment, the first adhesive tape  191  may surround the area around the first camera module  105 . For example, the first adhesive tape  191  may have, in at least a portion thereof, an opening  1911  in which the first camera module  105  is disposed. When the first adhesive tape  191  is attached to the plate  142  and the display  130  is attached to the first adhesive tape  191 , the first camera module  105  may face the rear surface (e.g., the surface facing the −z-axis direction) of the display  130  through the opening  1911 . 
     In an embodiment, the second adhesive tape  192  may be disposed between the plate  142  of the side member  140  and the back plate  180 . The second adhesive tape  192  may partially seal the space between the plate  142  and the back plate  180 . 
     In an embodiment, the waterproof structure  200  may interrupt a movement of liquid outside the electronic device  100  into the inner space S through the vent hole  143 . The waterproof structure  200  may be located between the display  130  and the plate  142  and may be attached to the plate  142 . For example, the waterproof structure  200  may be disposed at the position on the plate  142  that overlaps the second opening area  143   b  of the vent hole  143 . The waterproof structure  200  may interrupt a flow path of liquid between the second opening area  143   b  and the inner space S. 
     In an embodiment, the waterproof structure  200  may be attached to a partial area (e.g., a bonding area  144  of  FIG. 7 ) of the plate  142  to cover the second opening area  143   b . The waterproof structure  200  may be configured to interrupt a movement of liquid (e.g., water) into the inner space S and allow for a movement of gas (e.g., air) into the inner space S. For example, the waterproof structure  200  may be implemented by using a material (e.g., Gore-Tex) through which liquid cannot pass and air can pass. In various embodiments, the waterproof structure  200  may include a waterproof ventilation sheet (e.g., a membrane  210  of  FIGS. 8, 9A, and 9B ). The structure of the waterproof structure  200  and components thereof will be described below in more detail with reference to  FIGS. 8, 9A, 9B, 10, and 11 . 
       FIG. 7  illustrates a portion of a side member of an electronic device according to an embodiment of the disclosure. 
       FIG. 7  may be a view illustrating the portion of the side member  140  in which the vent hole  143  is formed and the portion of the side member  140  on which the waterproof structure (e.g., the waterproof structure  200  of  FIGS. 4A, 4B, 5, and 6 ) is disposed. 
       FIG. 7  may be a view illustrating the state in which the waterproof structure  200  and an adhesive tape (e.g., the first adhesive tape  191  of  FIGS. 4A, 4B, 5 , and  6 ) are not attached to the side member  140 . 
     Referring to  FIG. 7 , the side member  140  of the electronic device  100  according to an embodiment may include the bonding area  144  on which the waterproof structure  200  is disposed. Although the waterproof structure  200  is not illustrated in  FIG. 7 , the waterproof structure  200  may be attached to the bonding area  144 . In various embodiments, the bonding area  144  may be formed in a shape substantially corresponding to the waterproof structure  200 . 
     In an embodiment, the side member  140  may include the frame  141  and the plate  142 . The frame  141  of the side member  140  illustrated in  FIG. 7  may be referred to as the first sidewall (e.g., the first sidewall  141   a  of  FIGS. 4A, 4B, 5, and 6 ) in which the vent hole  143  is formed. 
     In an embodiment, the vent hole  143  may include the first opening area  143   a  formed in the first sidewall  141   a , the duct  143   c  extending from the first opening area  143   a  toward the plate  142 , and the second opening area  143   b  extending from the duct  143   c  so as to be formed in a partial area of the plate  142 . For example, the first opening area  143   a  may refer to the opening area formed in a portion of the first sidewall  141   a . The second opening area  143   b  may refer to the opening area formed in a portion of the plate  142 . The duct  143   c  may refer to the passage extending to connect the first opening area  143   a  and the second opening area  143   b . In various embodiments, the first opening area  143   a  may be open in the lateral direction of the electronic device  100  (e.g., in the +y-axis direction), and the second opening area  143   b  may be open in the direction toward the front side of the electronic device  100  (e.g., in the +z-axis direction). 
     In an embodiment, the bonding area  144  may be formed on a portion of the plate  142 . For example, the bonding area  144  may be formed around the area of the plate  142  in which the second opening area  143   b  is formed. The second opening area  143   b  may be formed at the position overlapping the boding area  144 . For example, the bonding area  144  may be formed on a partial area of the plate  142 , and the second opening area  143   b  may penetrate a portion of the bonding area  144 . As illustrated in  FIG. 7 , the second opening area  143   b  may be located within the bonding area  144 . In various embodiments, the waterproof structure  200  may be attached to the bonding area  144  and may cover the second opening area  143   b  accordingly. 
     In an embodiment, a partial area of the plate  142  may be recessed to form the bonding area  144 . For example, a partial area of the plate  142  may be recessed in a predetermined shape, and the bonding area  144  may be connected with the other area of the plate  142  with a step therebetween. As illustrated in  FIG. 7 , the bonding area  144  may be concavely recessed in the direction toward the rear side of the electronic device  100  (e.g., in the −z-axis direction). However, the shape of the bonding area  144  is not limited to the illustrated embodiment. According to various embodiments, the bonding area  144  may form substantially the same plane as the other areas of the plate  142 . 
     In an embodiment, the plate  142  may include a recess  145  connected with the second opening area  143   b . The recess  145  may be formed in the bonding area  144  of the plate  142 . For example, a portion of the bonding area  144  may be recessed to form the recess  145 . The recess  145  may have a predetermined length and may extend substantially parallel to the first sidewall  141   a.    
     In an embodiment, the recess  145  may be connected with, or may fluidly communicate with, the second opening area  143   b  such that fluid (e.g., liquid and/or gas) passing through the second opening area  143   b  moves into the recess  145 . For example, at least a portion of the recess  145  may be connected with the second opening area  143   b . The recess  145  may be formed such that at least a portion thereof overlaps the second opening area  143   b . For example, as illustrated in  FIG. 7 , when the bonding area  144  is viewed from above or the front (e.g., when the side member  140  is viewed in the −z-axis direction), the recess  145  may be located in the bonding area  144 , and the second opening area  143   b  may be located in the recess  145 . The second opening area  143   b  may be located adjacent to one end portion of the recess  1445 . However, the relative positions of the second opening area  143   b  and the recess  145  are not limited to the illustrated embodiment. According to various embodiments, the second opening area  143   b  may be located in the middle of the recess  145 . 
     In an embodiment, the recess  145  may provide a predetermined space for securing an amount of air introduced through the vent hole  143  (an amount of ventilation). For example, as the recess  145  is connected with the bonding area  144  with a step therebetween, the predetermined space surrounded by the recess  145  and the waterproof structure  200  may be formed when the waterproof structure (e.g., the waterproof structure  200  of  FIGS. 4A, 4B, 5, and 6 ) is attached to the bonding area  144 . In various embodiments, the space formed by the recess  145  and the waterproof structure  200  may be used as a space for reducing pressure applied to the waterproof structure  200  by water passing through the second opening area  143   b . For example, at least a portion of water passing through the second opening area  143   b  may flow in the space between the recess  145  and the waterproof structure  200 , and thus water pressure applied to the waterproof structure  200  may be reduced. 
       FIG. 8  illustrates a waterproof structure of an electronic device according to an embodiment of the disclosure. 
       FIG. 9A  illustrates a waterproof structure of an electronic device according to an embodiment of the disclosure. 
       FIG. 9B  illustrates a waterproof structure of an electronic device according to an embodiment of the disclosure. 
       FIG. 8  may illustrate a perspective view and an exploded perspective view of the waterproof structure  200 .  FIGS. 9A and 9B  may be sectional views of the waterproof structure  200  taken along line B-B′ illustrated in  FIG. 8 . 
     Referring to  FIGS. 8, 9A, and 9B , the waterproof structure  200  according to an embodiment may include the membrane  210 , a cover member  220 , a first adhesive member  230 , and a second adhesive member  240 . For example, the waterproof structure  200  may be formed in a structure in which the membrane  210 , the first adhesive member  230 , the cover member  220 , and the second adhesive member  240  are stacked one above another. 
     In an embodiment, the membrane  210  may be formed of a waterproof and air-permeable material. For example, the membrane  210  may provide a waterproof function of blocking liquid introduced from outside the electronic device  100  and may pass gas through the membrane  210 . In various embodiments, the membrane  210  may be a ventilation waterproof sheet or a waterproof ventilation sheet. For example, the membrane  210  may contain a Gore-Tex material. However, the material of the membrane  210  is not limited to the above-described example and may be formed of various waterproof and air-permeable materials. 
     In an embodiment, the membrane  210  may include a first surface  211  and a second surface facing away from the first surface  211 . For example, when the waterproof structure  200  is attached to the bonding area  144 , the first surface  211  may face toward the display  130 , and the second surface  212  may face toward the bonding area  144  (or, the plate  142  of the side member  140 ). The membrane  210  may be attached to the cover member  220  through the first adhesive member  230 . For example, the second surface  212  of the membrane  210  may be attached to the cover member  220  through the first adhesive member  230 . 
     In an embodiment, the cover member  220  may be attached to the second surface  212  of the membrane  210 . The cover member  220  may be formed of a material through which fluid (liquid and/or gas) cannot pass. For example, the cover member  220  may be formed of polyethylene terephthalate (PET). However, the material of the cover member  220  is not limited to the above-described example and may be formed of various waterproof and non-breathable materials. 
     In an embodiment, a through-hole  223  may be formed in a partial area of the cover member  220 . For example, the cover member  220  may include a third surface  221  facing the second surface  212  of the membrane  210  and a fourth surface  222  facing away from the third surface  221 . The through-hole  223  may penetrate the third surface  221  and the fourth surface  222 . 
     In an embodiment, the through-hole  223  may provide a passage through which fluid outside the electronic device  100  moves toward the membrane  210 . For example, the fluid may move into the space between the membrane  210  and the cover member  220  through the through-hole  223  as the cover member  220  is formed of a waterproof and non-breathable material. According to an embodiment, liquid introduced from outside the electronic device  100  may move through the through-hole  223  of the cover member  220 , and thus the pressure that the liquid directly applies or transmits to the membrane  210  by contact with the membrane  210  may be reduced. In various embodiments, the through-hole  223  of the cover member  220  may be formed to be smaller than openings  231  and  241  of the adhesive members  230  and  240 . 
     In an embodiment, the cover member  220  may be attached to the membrane  210  so as to be spaced apart from the second surface  212  of the membrane  210  by a predetermined gap G. For example, the third surface  221  of the cover member  220  may be attached to the second surface  212  of the membrane  210  through the first adhesive member  230 , and the second surface  212  of the membrane  210  and the third surface  221  of the cover member  220  may be spaced apart from each other by the predetermined gap G by the first adhesive member  230  (e.g., refer to  FIG. 9A ). For example, the predetermined gap G between the membrane  210  and the cover member  220  may be about 0.02 mm or more, but is not limited thereto. 
     In an embodiment, the cover member  220  may secure an amount of ventilation of the membrane  210  as the cover member  220  is attached to the membrane  210  so as to be spaced apart from the membrane  210  by the predetermined gap G. For example, the area (or, space) by which the membrane  210  makes contact with air may be secured by the predetermined gap G between the cover member  220  and the membrane  210 . 
     In an embodiment, the gap G between the cover member  220  and the membrane  210  may vary as the pressure P of liquid (e.g., water pressure) is applied to the cover member  220 . For example, when the water pressure P is transmitted to the cover member  220 , at least a portion of the cover member  220  may be moved toward the membrane  210  by the water pressure P and may partially make contact with the membrane  210  (e.g., refer to  FIG. 9B ). According to an embodiment, when liquid is introduced from outside the electronic device  100 , most of the pressure P of the liquid may be applied to the cover member  220 , and thus the pressure of the liquid transmitted to the membrane  210  may be reduced. 
     In an embodiment, the first adhesive member  230  may be disposed between the membrane  210  and the cover member  220 . For example, the first adhesive member  230  may be disposed between the second surface  212  of the membrane  210  and the third surface  221  of the cover member  220  and may attach the membrane  210  and the cover member  220  to each other. For example, the both sides of the first adhesive member  230  may be attached to the membrane  210  and the cover member  220 , respectively. In various embodiments, the first adhesive member  230  may include a double-sided tape. 
     In an embodiment, the first opening  231  may be formed in the central area of the first adhesive member  230 . For example, the first adhesive member  230  may be formed in a ring shape corresponding to the shapes of the peripheries of the membrane  210  and the cover member  220 . 
     In an embodiment, the second adhesive member  240  may be disposed on the fourth surface  222  of the cover member  220 . For example, the second adhesive member  240  may attach the cover member  220  to the bonding area  144 . In various embodiments, the second adhesive member  240  may be disposed between the fourth surface  222  of the cover member  220  and the bonding area (e.g., the bonding area  144  of  FIG. 7 ). For example, the both sides of the second adhesive member  240  may be attached to the cover member  220  and the bonding area  144 , respectively. In various embodiments, the second adhesive member  240  may include a double-sided tape. 
     In an embodiment, the second opening  241  may be formed in the central area of the second adhesive member  240 . For example, the second adhesive member  240  may be formed in a ring shape corresponding to the shapes of the peripheries of the membrane  210  and the cover member  220 . In various embodiments, the first adhesive member  230  and the second adhesive member  240  may be formed in substantially the same shape. For example, the shapes and/or sizes of the first opening  231  and the second opening  241  may be substantially the same as each other. 
     In an embodiment, the first opening  231  of the first adhesive member  230  and the second opening  241  of the second adhesive member  240  may overlap the through-hole  223  of the cover member  220 . For example, the through-hole  223  may be located inside the first opening  231  and the second opening  241 . In various embodiments, the through-hole  223  may be located adjacent to one of the edges of the first opening  231  and the second opening  241 . For example, each of the first opening  231  and the second opening  241  may include a first edge E 1  and a second edge E 2  that face each other in parallel. The through-hole  223  may be formed in a position adjacent to one of the first edge E 1  and the second edge E 2 . As illustrated in  FIG. 8 , the through-hole  223  may be located closer to the first edges E 1  of the openings  231  and  241  than to the second edges E 2  of the openings  231  and  241 . However, the position of the through-hole  223  is not limited to the illustrated embodiment. 
       FIG. 10  illustrates a side member and a waterproof structure of an electronic device according to an embodiment of the disclosure. 
       FIG. 11  illustrates a section of a portion of an electronic device according to an embodiment of the disclosure. 
       FIG. 10  may be a view illustrating the bonding area  144  to which the waterproof structure  200  is attached. For example, the enlarged view of  FIG. 10  may be a view in which the membrane  210  is omitted to describe the position of the through-hole  223  formed in the cover member  220 . 
       FIG. 11  may be a sectional view of the electronic device  100  taken along line C-C′ illustrated in  FIG. 10  according to an embodiment of the disclosure. For example,  FIG. 11  may be a view for explaining a flow path of liquid introduced from outside the electronic device  100 . 
     Referring to  FIGS. 10 and 11 , the electronic device  100  according to an embodiment may include the side member  140  (e.g., the side member  140  of  FIGS. 4A, 4B, 5, 6, and 7 ) having the vent hole  143  formed therein and the waterproof structure  200  (e.g., the waterproof structure  200  of  FIGS. 8, 9A, and 9B ) disposed on the side member  140  to cover the vent hole  143 . 
     Some of the components of the side member  140  and the waterproof structure  200  illustrated in  FIGS. 10 and 11  may be identical or similar to the components of the side member  140  and the waterproof structure  200  illustrated in  FIGS. 4A to 9B , and therefore repetitive descriptions will hereinafter be omitted. 
     In an embodiment, the side member  140  may include the frame  141  and the plate  142 , and the bonding area  144  to which the waterproof structure  200  is attached may be formed on the plate  142 . For example, the bonding area  144  may be formed in a shape corresponding to the waterproof structure  200 . In various embodiments, the bonding area  144  may be formed to be larger than the waterproof structure  200 . For example, the waterproof structure  200 , when attached to the bonding area  144 , may be surrounded by the periphery of the bonding area  144 . 
     In an embodiment, the waterproof structure  200  may be attached to the bonding area  144  of the plate  142 . The waterproof structure  200  may include the membrane  210 , the cover member  220  attached to the rear surface (e.g., the surface facing the −z-axis direction or the second surface  212  of  FIGS. 9A and 9B ) of the membrane  210 , the first adhesive member  230  that attaches the membrane  210  and the cover member  220  to each other, and the second adhesive member  240  that attaches the cover member  220  to the bonding area  144 . For example, the waterproof structure  200  may be attached to the bonding area  144  such that the membrane  210  faces the display  130  and the cover member  220  is located between the membrane  210  and the plate  142 . 
     In an embodiment, the waterproof structure  200  may cover a partial area of the vent hole  143 . For example, the waterproof structure  200  may cover the second opening area  143   b  of the vent hole  143  by attachment to the bonding area  144 . The waterproof structure  200  may provide a waterproof function by interrupting a movement of liquid passing through the second opening area  143   b  into the inner space S of the electronic device  100 . The waterproof structure  200  may overlap the second opening area  143   b  in the +z-axis direction with respect to  FIGS. 10 and 11 . For example, when the waterproof structure  200  is viewed from the front or above, the second opening area  143   b  may overlap at least a portion of the waterproof structure  200 . 
     In an embodiment, the waterproof structure  200  may be configured such that the through-hole  223  of the cover member  220  does not overlap the second opening area  143   b . For example, the through-hole  223  of the cover member  220  may be located so as not to be aligned with the second opening area  143   b . As illustrated in  FIG. 10 , when the waterproof structure  200  is viewed from the front or above, the through-hole  223  may be located to be spaced apart from the second opening area  143   b  by a predetermined gap (e.g., a first distance L 1 ) in a first direction d (e.g., the −x-axis direction) parallel to the first sidewall  141   a . For example, the first distance L 1  may refer to the distance between the periphery of the through-hole  223  and the periphery of the second opening area  143   b  adjacent to each other that is measured in a direction parallel to the first direction  . For example, as the through-hole  223  is located so as not to be aligned with the second opening area  143   b , at least a portion of liquid passing through the second opening area  143   b  may not be directly introduced into the through-hole  223  and may pass through the through-hole  223  after flowing in the space between the recess  145  and the waterproof structure  200 . For example, when the waterproof structure  200  is viewed from the front or above, the through-hole  223  may be located to be spaced apart from the second opening area  143   b  by about 1 mm or more in the first direction   (e.g., the −x-axis direction) parallel to the first sidewall  141   a . However, the first distance L 1  is not limited to the aforementioned numerical value. 
     In an embodiment, the through-hole  223  of the cover member  220  may be located between the opposite end portions of the recess  145  when the waterproof structure  200  is viewed from the front or above. For example, the second opening area  143   b  may overlap the one end portion of the recess  145 , and the through-hole  223  may overlap the central portion of the recess  145 . For example, as the through-hole  223  is located to overlap the central portion of the recess  145 , liquid passing through the second opening area  143   b  may not be introduced into the through-hole  223  immediately after moving to the opposite end portion (e.g., the end portion in the first direction  ) of the recess  145 . Accordingly, the flow path of the liquid may be elongated, and the pressure that the liquid applies to the membrane  210  by direct contact with the membrane  210  may be reduced. 
     Hereinafter, an operation in which the pressure of liquid is reduced by the waterproof structure  200  according to the embodiment of the disclosure when the liquid is introduced from outside the electronic device  100  will be described with reference to  FIG. 11 . 
     In an embodiment, liquid outside the electronic device  100  may be introduced into the duct  143   c  through the first opening area  143   a . The liquid introduced into the duct  143   c  may move toward the second opening area  143   b.    
     In an embodiment, the liquid passing through the second opening area  143   b  may collide with the cover member  220  of the waterproof structure  200 . The liquid may fail to pass through the cover member  220 , and the pressure of the liquid may be reduced by the collision with the cover member  220 . 
     In an embodiment, the flow path of the liquid may be changed by the cover member  220 . For example, after the collision with the cover member  220 , the liquid passing through the second opening area  143   b  may move in the first direction and may flow into the recess  145 . At least a portion of the liquid introduced into the recess  145  may collide with the end portion of the recess  145  that faces the first direction  1 , and the pressure of the liquid may be reduced. 
     In an embodiment, at least a portion of the liquid introduced into the recess  145  may flow in the recess  145  and thereafter may pass through the through-hole  223  of the cover member  220 . For example, the liquid moving in the first direction   and flowing into the recess  145  may collide with the end portion  1451  of the recess  145  that faces the first direction  , and therefore the flow path may be changed to the direction opposite to the first direction  . 
     In an embodiment, the liquid passing through the through-hole  223  may be in a low-pressure state as the liquid collides with the cover member  220  and flows in the recess  145 . The waterproof structure  200  according to the embodiment may include the cover member  220  having the through-hole  223  formed therein and thus may reduce the pressure of the liquid finally delivered to the membrane  210 . For example, the through-hole  223  of the cover member  220  may not be aligned with the second opening area  143   b  in the z-axis direction, and thus the liquid passing through the second opening area  143   b  may move toward the recess  145  without directly passing through the through-hole  223 . For example, the through-hole  223  of the cover member  220  may be located between the end portion  1451  of the recess  145 , which faces the first direction  , and the second opening area  143   b . Accordingly, the path along which the liquid flows to reach the through-hole  223  may be increased, and the pressure of the liquid may be reduced. 
     In an embodiment, as the liquid passing through the second opening area  143   b  collides with the cover member  220 , at least a portion of the cover member  220  may be moved toward the membrane  210  by the pressure of the liquid. For example, at least a portion of the cover member  220  may be brought into close contact with the membrane  210  by the pressure of the liquid. Accordingly, the area of the membrane  210  making contact with the liquid may be decreased, and the pressure of the liquid transmitted to the membrane  210  may be reduced. 
       FIG. 12  illustrates a side member, a waterproof structure, and a layer structure of an electronic device according to an embodiment of the disclosure. 
       FIG. 12  may be a view illustrating an operation in which the waterproof structure  200  and the layer structure  300  are coupled to the side member  140  and a state in which the layer structure  300  is disassembled. 
     Referring to  FIG. 12 , the electronic device  100  according to an embodiment may include the side member  140  including the frame  141  and the plate  142 , and the waterproof structure  200  and the layer structure  300  that are disposed on the bonding area  144  of the side member  140 . 
     Some of the components of the side member  140  and the waterproof structure  200  illustrated in  FIG. 12  may be identical or similar to the components of the side member  140  and the waterproof structure  200  illustrated in  FIGS. 4A, 4B, 5, 6, 7, 8, 9A, 9B, 10, and 11 . For example, the waterproof structure  200  may be referred to as the waterproof structure  200  illustrated in  FIGS. 8, 9A, 9B, 10, and 11  and may include a membrane (e.g., the membrane  210  of  FIGS. 8, 9A, 9B, 10, and 11 ), a cover member (e.g., the cover member  220  of  FIGS. 8, 9A, 9B, 10, and 11 ), and adhesive members (e.g., the first adhesive member  230  and the second adhesive member  240  of  FIGS. 8, 9A, 9B, 10, and 11 ). Hereinafter, repetitive descriptions will be omitted. 
     In an embodiment, the layer structure  300  may be disposed between the waterproof structure  200  and the bonding area  144 . For example, the layer structure  300  may be attached to the bonding area  144 , and the waterproof structure  200  may be attached above the layer structure  300  (e.g., in the +z-axis direction). For example, the layer structure  300  may be formed in a shape corresponding to the bonding area  144  and the waterproof structure  200 . In various embodiments, fluid (liquid and/or gas) introduced into a vent hole (e.g., the vent hole  143  of  FIGS. 4A, 4B, 5, 6, and 7 ) of the side member  140  may move to the waterproof structure  200  through the layer structure  300 . 
     In an embodiment, the layer structure  300  may contain a material through which fluid cannot pass. For example, the fluid may move toward the waterproof structure  200  through an opening area formed in the layer structure  300 . The layer structure  300  may be configured to provide a passage through which the fluid introduced into the vent hole  143  moves. 
     In an embodiment, the layer structure  300  may include a first sheet  310 , a second sheet  320 , a third adhesive member  330 , and a fourth adhesive member  340 . For example, the layer structure  300  may be formed in a structure in which the second sheet  320 , the fourth adhesive member  340 , the first sheet  310 , and the third adhesive member  330  are stacked one above another. 
     In an embodiment, the first sheet  310  may be attached to the bonding area  144 . For example, the first sheet  310  may be attached to the bonding area  144  through the third adhesive member  330 . The first sheet  310  may be formed of a material through which fluid (liquid and/or gas) cannot pass. For example, the first sheet  310  may be formed of polyethylene terephthalate (PET). However, the material of the first sheet  310  is not limited to the above-described example and may be formed of various waterproof and non-breathable materials. 
     In an embodiment, the first sheet  310  may include a fifth surface  313  and a sixth surface  314  facing away from the fifth surface  313 . The fifth surface  313  may face toward the second sheet  320  and the fourth adhesive member  340 , and the sixth surface  314  may face toward the bonding area  144  and the third adhesive member  330 . For example, the sixth surface  314  of the first sheet  310  may be attached with the third adhesive member  330 . 
     In an embodiment, a first hole  311  may be formed in the first sheet  310 . The first hole  311  may form a flow passage of fluid together with opening areas (e.g., a second hole  321 , a third opening  331 , and a fourth opening  341 ) that are formed in the second sheet  320 , the third adhesive member  330 , and the fourth adhesive member  340 . For example, the first hole  311  may be connected with a partial area of the third opening  331  of the third adhesive member  330  and a partial area of the fourth opening  341  of the fourth adhesive member  340 . For example, the first hole  311  may partially overlap the third opening  331  and the fourth opening  341 . The first hole  311  may not overlap the second hole  321  of the second sheet  320 . 
     In an embodiment, the second sheet  320  may be attached to the first sheet  310 . For example, the second sheet  320  may be attached to the first sheet  310  through the fourth adhesive member  340 . The second sheet  320  may be formed of a material through which fluid (liquid and/or gas) cannot pass. For example, the second sheet  320  may be formed of polyethylene terephthalate (PET). However, the material of the second sheet  320  is not limited to the above-described example. In various embodiments, the second sheet  320  may be formed of substantially the same material as the first sheet  310 . 
     In an embodiment, the second sheet  320  may include a seventh surface  323  and an eighth surface  324  facing away from the seventh surface  323 . The seventh surface  323  may face toward the waterproof structure  200 , and the eighth surface  324  may face toward the first sheet  310  and the fourth adhesive member  340 . The waterproof structure  200  may be disposed on the seventh surface  323  of the second sheet  320 . For example, the seventh surface  323  of the second sheet  320  may be attached with the waterproof structure  200  (e.g., the second adhesive member  240  of the waterproof structure  200  of  FIGS. 8, 9A, 9B, 10, and 11 ). For example, the eighth surface  324  of the second sheet  320  may be attached with the fourth adhesive member  340 . 
     In an embodiment, the second hole  321  may be formed in the second sheet  320 . The second hole  321  may form a flow passage of fluid together with opening areas (e.g., the first hole  311 , the third opening  331 , and the fourth opening  341 ) that are formed in the first sheet  310 , the third adhesive member  330 , and the fourth adhesive member  340 . For example, the second hole  321  may be connected to a partial area of the fourth opening  341  of the fourth adhesive member  340 . For example, the second hole  321  may partially overlap the fourth opening  341 . The second hole  321  may not overlap the first hole  311  of the first sheet  310 . 
     In an embodiment, the third adhesive member  330  may be disposed between the first sheet  310  and the bonding area  144 . For example, the third adhesive member  330  may attach the first sheet  310  to the bonding area  144 . For example, the both sides of the third adhesive member  330  may be attached to the first sheet  310  and the bonding area  144 , respectively. In various embodiments, the third adhesive member  330  may include a double-sided tape. 
     In an embodiment, the third opening  331  may be formed in the central area of the third adhesive member  330 . The third opening  331  may be formed in the central area of the third adhesive member  330  to have a predetermined length. A partial area of the third opening  331  may be connected with the first hole  311  of the first sheet  310 . For example, when the third adhesive member  330  is attached to the first sheet  310 , one end portion of the third opening  331  may overlap the first hole  311 . 
     In an embodiment, the fourth adhesive member  340  may be disposed between the first sheet  310  and the second sheet  320 . For example, the fourth adhesive member  340  may attach the first sheet  310  and the second sheet  320  to each other. For example, the both sides of the fourth adhesive member  340  may be attached to the first sheet  310  and the second sheet  320 , respectively. In various embodiments, the fourth adhesive member  340  may include a double-sided tape. 
     In an embodiment, the fourth opening  341  may be formed in the central area of the fourth adhesive member  340 . The fourth opening  341  may be formed in the central area of the fourth adhesive member  340  to have a predetermined length. A partial area (e.g., a first area  343 ) of the fourth opening  341  may be connected with the first hole  311  of the first sheet  310 , and another partial area (e.g., a second area  345 ) may be connected with the second hole  321  of the second sheet  320 . For example, when the fourth adhesive member  340  is attached to the first sheet  310  and the second sheet  320 , the first area  343  (or, one end portion) of the fourth opening  341  may overlap the first hole  311  and a portion of the third opening  331 , and the second area  345  (or, an opposite end portion) of the fourth opening  341  may overlap the second hole  321 . The first area  343  and the second area  345  may be located to be spaced apart from each other by a second distance L 2  in the x-axis direction to correspond to the positions of the first hole  311  and the second hole  321 . 
     In an embodiment, the first hole  311  of the first sheet  310 , the second hole  321  of the second sheet  320 , the third opening  331  of the third adhesive member  330 , and the fourth opening  341  of the fourth adhesive member  340  may fluidly communicate with each other or may be connected with each other, and thus the layer structure  300  may provide a passage through which fluid moves. In various embodiments, fluid introduced into the vent hole  143  may move to the waterproof structure  200  through the passage formed by the layer structure  300 . For example, when liquid is introduced into the vent hole  143 , the pressure of the liquid may be reduced while the liquid passes through the passage of the layer structure  300 . Accordingly, the pressure of the liquid transmitted to the waterproof structure  200  may be reduced, and the waterproof function of the electronic device  100  may be improved. An operation in which liquid passes through the layer structure  300  will be described below with reference to  FIGS. 13 and 14 . 
       FIG. 13  illustrates a section of a portion of an electronic device according to an embodiment of the disclosure. 
       FIG. 14  illustrates a side member and a layer structure of an electronic device according to an embodiment of the disclosure. 
       FIGS. 13 and 14  may be views for explaining a flow path of liquid introduced from outside the electronic device  100 . For example,  FIG. 14  may be a view illustrating an operation in which the components of the layer structure  300  are sequentially attached. 
     Referring to  FIGS. 13 and 14 , the electronic device  100  according to an embodiment may include the front plate  120 , the display  130 , the side member  140 , the waterproof structure  200 , and the layer structure  300 . 
     In an embodiment, the waterproof structure  200  may be attached to the second sheet  320  of the layer structure  300  so as to be located between the layer structure  300  and the display  130 . For example, the waterproof structure  200  illustrated in  FIG. 14  may be referred to as the waterproof structure  200  of  FIGS. 8, 9A, 9B, 10 , and  11 . 
     In an embodiment, the layer structure  300  may be attached to the bonding area  144  of the plate  142 . The layer structure  300  may include the first sheet  310  attached to the bonding area  144 , the second sheet  320  attached to the first sheet  310 , the third adhesive member  330  attaching the first sheet  310  to the bonding area  144 , and the fourth adhesive member  340  attaching the second sheet  320  to the first sheet  310 . 
     In an embodiment, the layer structure  300  may be attached to the bonding area  144  and may cover the second opening area  143   b  of the vent hole  143  accordingly. The layer structure  300  may overlap the second opening area  143   b  in the +z-axis direction with respect to  FIGS. 13 and 14 . For example, when the layer structure  300  is viewed from the front or above, the second opening area  143   b  may overlap at least a portion of the layer structure  300 . 
     In an embodiment, the layer structure  300  may be configured such that the first hole  311  of the first sheet  310  does not overlap the second opening area  143   b . For example, the first hole  311  of the first sheet  310  may be located so as not to be aligned with the second opening area  143   b  in the z-axis direction. With respect to  FIG. 14 , when the layer structure  300  is viewed from the front or above, the first hole  311  may be located to be spaced apart from the second opening area  143   b  by a specified third distance L 3  in the first direction  . For example, with respect to  FIG. 14 , when the layer structure  300  is viewed from the front or above, the first hole  311  may be located to be spaced apart from the second opening area  143   b  by about 1 mm or more in the first direction  . However, the third distance L 3  is not limited to the aforementioned numerical value. 
     In an embodiment, the layer structure  300  may be configured such that the second hole  321  of the second sheet  320  does not overlap the first hole  311  of the first sheet  310 . For example, the second hole  321  of the second sheet  320  may be located so as not to be aligned with the first hole  311  in the z-axis direction. With respect to  FIG. 14 , when the layer structure  300  is viewed from the front or above, the second hole  321  may be located to be spaced apart from the first hole  311  by a specified fourth distance L 4  in the direction opposite to the first direction  . For example, with respect to  FIG. 14 , when the layer structure  300  is viewed from the front or above, the second hole  321  may be located to be spaced apart from the first hole  311  by about 1 mm or more in the direction opposite to the first direction  . However, the fourth distance L 4  is not limited to the aforementioned numerical value. In an embodiment, the first hole  311  of the first sheet  310  may be connected with the third opening  331  of the third adhesive member  330  and the fourth opening  341  of the fourth adhesive member  340 . For example, with respect to  FIG. 14 , when the layer structure  300  is viewed from the front or above, the first hole  311  may overlap a partial area of the third opening  331  and a partial area of the fourth opening  341 . For example, the partial areas of the third opening  331  and the fourth opening  341  may be areas adjacent to an end portion facing the first direction  . 
     In an embodiment, the second hole  321  of the second sheet  320  may be connected with the fourth opening  341  of the fourth adhesive member  340 . For example, with respect to  FIG. 14 , when the layer structure  300  is viewed from the front or above, the second hole  321  may overlap another partial area of the fourth opening  341 . For example, the fourth opening  341  may be configured such that the area overlapping the first hole  311  is spaced apart from the area overlapping the second hole  321  by a specified distance (e.g., the second distance L 2  of  FIG. 12 ) in the first direction  . For example, the area of the fourth opening  341  that overlaps the second hole  321  may be an area (e.g., the second area  345  of  FIG. 12 ) that is adjacent to an end portion facing the direction (e.g., the +x-axis direction) opposite to the first direction  . For example, the fourth opening  341  may be configured such that the area (e.g., the first area  343  of  FIG. 12 ) overlapping the first hole  311  is spaced apart from the area (e.g., the second area  345  of  FIG. 12 ) overlapping the second hole  321  by about 1 mm or more in the first direction d (e.g., the −x-axis direction with respect to  FIG. 12 ). However, the distance (e.g., the second distance L 2 ) between the first area  343  and the second area  345  is not limited to the aforementioned numerical value. 
     Hereinafter, an operation in which the pressure of liquid is reduced by the layer structure  300  according to the embodiment of the disclosure when the liquid is introduced from outside the electronic device  100  will be described with reference to  FIGS. 13 and 14 . 
     In an embodiment, liquid outside the electronic device  100  may be introduced into the duct  143   c  through the first opening area  143   a . The liquid introduced into the duct  143   c  may move toward the second opening area  143   b.    
     In an embodiment, the liquid passing through the second opening area  143   b  may collide with the first sheet  310  of the layer structure  300 . The liquid may fail to pass through the first sheet  310 , and the pressure of the liquid may be reduced by the collision with the first sheet  310 . 
     In an embodiment, the flow path of the liquid passing through the second opening area  143   b  may be changed by the first sheet  310 . For example, the liquid passing through the second opening area  143   b , after colliding with the first sheet  310 , may move in the first direction d and may pass through the first hole  311  of the first sheet  310 . At this time, the pressure of the liquid may be reduced while the liquid collides with the inside surface of the side member  140  before passing through the first hole  311 . 
     In an embodiment, the liquid passing through the first hole  311  may collide with the second sheet  320 . The liquid may fail to pass through the second sheet  320 , and the pressure of the liquid may be reduced by the collision with the second sheet  320 . 
     In an embodiment, the flow path of the liquid passing through the first hole  311  may be changed by the second sheet  320 . For example, the liquid passing through the first hole  311 , after colliding with the second sheet  320 , may move in the direction opposite to the first direction d and may pass through the second hole  321  of the second sheet  320 . In various embodiments, the liquid passing through the first hole  311  may move toward the second hole  321  along the fourth opening  341  of the fourth adhesive member  340 . For example, the fourth opening  341  may be formed in a shape in which at least a portion is curved or bent, and thus the pressure of the liquid moving along the fourth opening  341  may be reduced. 
     According to an embodiment, the electronic device  100  may include, between the waterproof structure  200  and the vent hole  143 , the layer structure  300  having a flow passage formed therein, and thus the flow path of the liquid moving toward the waterproof structure  200  may be implemented to be long and complicated. 
       FIG. 15  illustrates a section of a portion of an electronic device according to an embodiment of the disclosure. 
       FIG. 16  illustrates a section of a portion of an electronic device according to an embodiment of the disclosure. 
       FIGS. 15 and 16  may be views illustrating embodiments in which the shape of the vent hole  143  is changed, as compared with the section of the electronic device  100  illustrated in  FIG. 6 . 
     Referring to  FIG. 15 , the electronic device  100  according to an embodiment may include the front plate  120 , the display  130 , the side member  140 , the printed circuit board  150 , the rear case  160 , the back plate  180 , and the waterproof structure  200 . 
     In an embodiment, the side member  140  may include the vent hole  143  that passes through the frame  141  and at least a portion of the plate  142 . For example, the vent hole  143  may include the first opening area  143   a  formed in the frame  141 , the second opening area  143   b  formed in the plate  142 , and the duct  143   c  connecting the first opening area  143   a  and the second opening area  143   b.    
     In an embodiment, the vent hole  143  may be formed such that at least a portion of the duct  143   c  extends to be inclined in a direction away from the waterproof structure  200 . For example, the duct  143   c  may include a first portion  143   d  extending from the first opening area  143   a  toward the inner space S and a second portion  143   e  extending from the first portion  143   d  toward the second opening area  143   b.    
     In an embodiment, the first portion  143   d  of the duct  143   c  may be formed to be inclined in a direction (e.g., the −z-axis direction) toward the back plate  180  with an approach to the inner space S. For example, the first portion  143   d  may be formed in a shape farther away from the waterproof structure  200  and/or the second opening area  143   b  with an approach to the inner space S. 
     In an embodiment, as the first portion  143   d  is formed to be inclined in the direction away from the waterproof structure  200 , the flow path along which liquid introduced into the duct  143   c  reaches the waterproof structure  200  may be elongated, and the direction in which the liquid moves may be changed. 
     In an embodiment, the length of the second portion  143   e  of the duct  143   c  may be changed depending on the degree to which the first portion  143   d  is inclined. For example, the length of the second portion  143   e  may be increased with an increase in the degree to which the first portion  143   d  is inclined toward the back plate  180 . 
     In an embodiment, the liquid introduced into the duct  143   c  may be farther away from the waterproof structure  200  as the liquid moves along the first portion  143   d . The liquid passing through the first portion  143   d  may collide with an inside surface  146  of the second portion  143   e , and thus the pressure of the liquid may be reduced. For example, as the liquid passing through the first opening area  143   a  passes through the duct  143   c  formed to be inclined toward the back plate  180 , the pressure of the liquid may be lowered, and thus the pressure of the liquid transmitted to the waterproof structure  200  may be reduced. 
     Referring to  FIG. 16 , a recessed area  147  connected with the duct  143   c  of the vent hole  143  may be formed on the side member  140  of the electronic device  100  according to an embodiment. 
       FIG. 16  may be a view illustrating an embodiment in which the recessed area  147  is additionally formed in the electronic device  100  illustrated in  FIG. 15 . Hereinafter, repetitive descriptions will be omitted, and the following description will be focused on the changed portion. 
     In an embodiment, at least a portion of the inside surface  146  of the second portion  143   e  may be concavely recessed to form the recessed area  147 . For example, the recessed area  147  may be connected with the first portion  143   d  and the second portion  143   e . The recessed area  147  may provide a space into which liquid moving along the first portion  143   d  is introduced. For example, the liquid passing through the first portion  143   d  may be introduced into the recessed area  147  and may collide with an inside surface  148  of the recessed area  147 , and thus the pressure of the liquid may be reduced. 
     According to an embodiment, a space in which the liquid introduced into the duct  143   c  flows may be secured by the recessed area  147 , and the flow path along which the liquid introduced into the duct  143   c  reaches the waterproof structure  200  may be elongated. 
       FIG. 17  illustrates a side member and a pin of an electronic device according to an embodiment of the disclosure. 
       FIG. 18  illustrates a pin of an electronic device according to an embodiment of the disclosure. 
     Referring to  FIGS. 17 and 18 , the electronic device  100  according to an embodiment may include the side member  140 , the waterproof structure  200 , and the pin  194 . 
     In an embodiment, the side member  140  may include the vent hole  143  extending from a partial area of the frame  141  to a partial area of the plate  142 . In an embodiment, the pin  194  may be inserted into at least a portion of the vent hole  143 . For example, the vent hole  143  may be configured such that the area or size of an opening area is decreased by the pin  194  inserted into the vent hole  143 . 
     In an embodiment, the pin  194  may be inserted into the vent hole  143 . For example, the pin  194  may be inserted into the vent hole  143  through the first opening area  143   a  of the vent hole  143  formed in the frame  141 . In various embodiments, the pin  194  may be located in the duct (e.g., the duct  143   c  of  FIGS. 19 and 20 ) of the vent hole  143 . A coupling structure of the pin  194  and the vent hole  143  will be described below with reference to  FIGS. 19 and 20 . 
     In an embodiment, the pin  194  may include a body  194   a , first protrusions  194   b  protruding from a central portion of the body  194   a , and second protrusions  194   c  protruding from at least one of opposite end portions of the body  194   a.    
     In an embodiment, the body  194   a  may be formed in a shape corresponding to the vent hole  143 . For example, the body  194   a  may be formed in a substantially cylindrical shape. The body  194   a  may be formed to be smaller than the vent hole  143  so as to be inserted into the vent hole  143 . In various embodiments, the body  194   a  may be formed such that the diameter of the central portion is greater than the diameters of the opposite end portions. However, the shape of the body  194   a  is not limited to the illustrated embodiment and may be changed to various shapes. 
     In an embodiment, the first protrusions  194   b  may be formed along the outer circumferential surface of the central portion of the body  194   a . For example, the first protrusions  194   b  may protrude from the outer circumferential surface of the body  194   a . For example, a plurality of first protrusions  194   b  may be formed. When the pin  194  is inserted into the vent hole  143 , the first protrusions  194   b  may be brought into close contact with the inside surface of the vent hole  143 , and thus the size of the opening area of the vent hole  143  may be decreased. For example, when the opening area of the vent hole  143  is decreased, a space in which fluid moves may be decreased, and thus the amount of fluid introduced may be reduced. 
     In an embodiment, the second protrusions  194   b  may protrude from the opposite end portions of the body  194   a . Although the second protrusions  194   c  protrude from the opposite end portions of the body  194   a  according to the illustrated embodiment, this is illustrative, and the second protrusions  194   c  may be formed on at least one of the opposite end portions of the body  194   a . When the pin  194  is inserted into the vent hole  143 , the second protrusions  194   c  may be stopped by the inside of the vent hole  143 , and thus the pin  194  may be fastened so as not to be separated from the vent hole  143 . 
     In an embodiment, the pin  194  may be formed to be symmetric with respect to the central portion of the body  194   a . For example, the pin  194  may be formed to be bilaterally symmetric and thus may be fastened without a limitation in an insertion direction when inserted into the vent hole  143 . 
     The pin  194  illustrated in  FIG. 18  is illustrative, and the shape of the pin  194  is not limited to the illustrated embodiment. The pin  194  may function to reduce the opening area by partially closing the vent hole  143  and may be changed to various shapes within such a range as to provide the function. 
       FIG. 19  illustrates a coupling structure of a side member and a pin of an electronic device according to an embodiment of the disclosure. 
       FIG. 20  illustrates the coupling structure of a side member and a pin of an electronic device according to an embodiment of the disclosure. 
     Referring to  FIGS. 19 and 20 , the electronic device  100  according to an embodiment may include the side member  140  including the vent hole  143 , the waterproof structure  200  attached to the side member  140 , and the pin  194  inserted into at least a portion of the vent hole  143 . 
     In an embodiment, the pin  194  may be inserted into the vent hole  143 . For example, the pin  194  may be inserted into the duct  143   c  of the vent hole  143 . The pin  194  inserted into the duct  143   c  may close at least a portion of the duct  143   c.    
     In an embodiment, the pin  194  may be inserted into the duct  143   c , and at least a portion of the pin  194  may be brought into close contact with the inside surface of the duct  143   c . For example, the first protrusions  194   b  of the pin  194  may make contact with the inside surface of the duct  143   c . In various embodiments, the first protrusions  194   b  may be inserted into the duct  143   c  while overlapping the inside surface of the duct  143   c . For example, the diameter of a virtual circle connecting the outside edges of the first protrusions  194   b  may be greater than the diameter of the duct  143   c.    
     In various embodiments, the first protrusions  194   b  may partially contain a flexible material or an elastic material so as to deform while being brought into close contact with the inner wall of the duct  143   c  as the pin  194  is inserted into the duct  143   c.    
     In an embodiment, the size of the opening area of the duct  143   c  may be decreased when the pin  194  is inserted into the duct  143   c . For example, when the cross-section of the pin  194  and the duct  143   c  in one direction is viewed, the pin  194  may close at least a portion of the entire area of the duct  143   c , and the remaining partial areas may be open through between the first protrusions  194   b.    
     In an embodiment, fluid introduced through the first opening area  143   a  may pass through the opening area of the duct  143   c  and may move to the second opening area  143   b . For example, the pin  194  may decrease the area of a passage through which the fluid moves. In various embodiments, when liquid outside the electronic device  100  is introduced into the vent hole  143 , a flow of the liquid passing through the first opening area  143   a  toward the second opening area  143   b  may be restricted by the pin  194  in a predetermined range. Accordingly, the amount of liquid delivered to the waterproof structure  200  may be decreased, and the pressure of the liquid transmitted to the waterproof structure  200  may be reduced. 
     In an embodiment, the pin  194  may be configured such that the second protrusions  194   c  are stopped by an inside wall  149  of the vent hole  143  when the pin  194  is inserted into the vent hole  143 . For example, the second protrusions  194   c  may be stopped by the inside wall  149  of the side member  140  that surrounds the duct  143   c . Accordingly, the pin  194  may be prevented from being separated from the vent hole  143 .

     The electronic device according to various embodiments may be one of various types of electronic devices. The electronic devices may include, for example, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance. According to an embodiment of the disclosure, the electronic devices are not limited to those described above. 
     It should be appreciated that various embodiments of the disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively,” as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element. 
     As used in connection with various embodiments of the disclosure, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry.” A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC). 
     Various embodiments as set forth herein may be implemented as software (e.g., the program  440 ) including one or more instructions that are stored in a storage medium (e.g., internal memory  436  or external memory  438 ) that is readable by a machine (e.g., the electronic device  401 ). For example, a processor (e.g., the processor  420 ) of the machine (e.g., the electronic device  401 ) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium. 
     According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer&#39;s server, a server of the application store, or a relay server. 
     According to various embodiments, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities, and some of the multiple entities may be separately disposed in different components. According to various embodiments, one or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In such a case, according to various embodiments, the integrated component may perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to various embodiments, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added. 
     While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
