     In the following description of the disclosure, the duct structure  10 , which is configured to provide a sound delivery path of the electronic device  300 , will be described with reference to the drawings. 
     First, according to various embodiments, the support member constituting the duct structure  10  and various embodiments including various elements coupled to the support member will be described with reference to  FIGS.  5  and  6   . 
     First, in the following description of this disclosure, it will be mainly described that a sound output path from the sound module  341  to the outside of the electronic device  200 , which is provided by the duct structure (e.g., the duct structure  10 ,  11 , or  12  of  FIGS.  5  to  11 ,  12 A to  12 C, and  13 A to  13 F ) will be described with reference to  FIGS.  5  and  6   . However, it may be merely an example. As an example, when the sound module  341  is provided as a sound input module such as a microphone, the same description may be applied to the sound input path which allows sound to be delivered from the outside of the electronic device  200  to the sound module  341 , and description of embodiments of the disclosure should not be interpreted as being limited to terms. 
       FIG.  5    is an exploded perspective view showing a part of a duct structure according to an embodiment of the disclosure.  FIG.  6    is a view showing a support member to which elements of  FIG.  4    are coupled according to an embodiment of the disclosure. 
     Referring to  FIGS.  5  and  6   , the duct structure  10  may include at least a part or all of a support member  400 , a shielding member  420 , and an auxiliary member  430 . The description of the duct area A of  FIG.  4    may be applied correspondingly to the description of the support member  400  of  FIGS.  5  and  6   , and all or a part of the support member  400  may be similar to or the same as the support member  311  of  FIG.  4   . According to an embodiment, the shielding member  420  may be configured to shield the leakage of sound emitted from a sound module (e.g., the sound module  341  of  FIG.  4   ). According to an embodiment, the auxiliary member  430  may be configured to provide an emission path which allows sound emitted from the sound module  341  (see  FIG.  4   ) to be emitted to the outside. 
     According to an embodiment, an inlet opening  411  may be formed through a front surface  401  of the support member  400 . For example, the front surface  401  may mean a surface in a direction (the +Z-axis direction) in which a display module (e.g., the display module  330  of  FIG.  4   ) of the support member  400  is disposed. The inlet opening  411  may be configured to provide a path into which sound emitted from the sound module  341  is introduced. According to an embodiment, the sound module  341  may be disposed in an accommodation portion (e.g., the accommodation portion  460  of  FIG.  7   ) formed on the lower surface (for example, the rear surface of the front surface  401 ) of the support member  400 . For example, the accommodation portion (e.g., the accommodation portion  460  of  FIG.  7   ) may be formed at a position corresponding to the inlet opening  411 . As another example, the sound module  341  may be disposed on the lower surface of the support member  400 , which corresponds to the inlet opening  411 , and may be configured to emit sound such that the emitted sound is delivered through the inlet opening  411 . 
     According to an embodiment, the shielding member  420  may be disposed near the inlet opening  411 . For example, a shielding member accommodation area  410  may be formed near the inlet opening  411 , and the shielding member  420  may be seated in the shielding member accommodation area  410 . For example, the inlet opening  411  is formed inside the shielding member accommodation area  410 , and in order to prevent the leakage of sound emitted from the inlet opening  411 , the shielding member  420  may be disposed in the shielding member accommodation area  410  so as to surround all or a part of the inlet opening  411 . According to an embodiment, the shielding member accommodation area  410  may be formed as a concave part on the front surface  401 . 
     According to an embodiment, a passing area  421 , which is connected to a first discharge conduit  402 , may be formed in a partial area of the shielding member  420 . Sound emitted from the sound module  341  may be introduced into the first discharge conduit  402  through the passing area  421 . According to an embodiment, the passing area  421  may be formed by cutting a part of the shielding member  420  so as to be formed as an incision area  421 . For example, a part of the shielding member  420 , which corresponds to the position of the first discharge conduit  402 , may be cut, and thus sound emitted through the inlet opening  411  may be delivered to the first discharge conduit  402  via the incision area  421 . However, it may be merely an example, and a passing area connected to the first discharge conduit  402  may be formed in a part of the shielding member  420  by various manners. 
     According to various embodiments, the first discharge conduit  402  may be formed on the front surface  401 .

According to an embodiment, the sound output conduit  404   a  may have one end connected to the first discharge conduit  402 . For example, sound emitted from the sound module  341  may pass sequentially through the first discharge conduit  402  and the sound output conduit  404   a , and then may be emitted to the outside. 
     According to various embodiments, the auxiliary member  430  may be disposed in the sound output area  404 . The auxiliary member  430  may be disposed on the sound output area  404  so as to prevent foreign materials from being introduced into the sound output area  404 . According to an embodiment, the auxiliary member  430  may include multiple openings  432 . The multiple openings  432  may be arranged at positions corresponding to the sound output conduit  404   a  so as to deliver sound emitted from the sound output conduit  404   a  to the outside of the electronic device  100 . According to an embodiment, the auxiliary member  430  may be disposed to overlap at least a part of the sound output conduit  404   a , and thus sound emitted from the sound output conduit  404   a  may be delivered to the outside through the opening  432 . 
     According to an embodiment, a support portion  403  may be formed in the first discharge conduit  402 . For example, the support portion  403  may be configured to support at least a part of the auxiliary member  430 . The support portion  403  may be configured to support at least a part of the auxiliary member  430 , and thus it may be possible to prevent deformation of the auxiliary member  430  due to a load or external force. The support portion  403  may be formed as a protrusion in the first discharge conduit  402 . 
     According to an embodiment, an adhesive member  490  may be disposed when the auxiliary member  430  is disposed on the sound output area  404 . The adhesive member  490  may be disposed on all or a part of the side wall  450  and the auxiliary member  430  in order for attachment of the display module  330 . The adhesive member  490  may include a liquid material, a solid material, and/or a semi-solid material. As will be described later, the display module  330  may be attached on the support member  400  so as to prevent sound emitted from the sound module  341  from leaking to the outside. In addition, the support member  400  and the display module  330  may be combined to form an emission path (e.g., see the first path  415  of  FIG.  8   )) of sound emitted from the sound module  341 .

According to an embodiment, the second conduit  413  may be connected to the inlet opening  411  so as to deliver sound emitted from the sound module  341  thereto. In the description of  FIG.  7   , the Y′-axis may be interpreted as an axis parallel to the A-A′ axis of  FIG.  6   . 
     According to an embodiment, the second conduit  413  may be formed by at least a part of the support member  400 , which extends therethrough. For example, the second conduit  413  may be formed in a space between a first surface  412   a  and a second surface  412   b  of the support member  400 . For example, the first surface  412   a  may mean the upper surface of the shielding member accommodation area  410 , and the second surface  412   b  may mean a lower surface of the shielding member accommodation area. According to an embodiment, the second conduit  413  may be connected to the inlet opening  411 . For example, the second conduit  413  may be formed between the first surface  412   a  and the second surface  412   b  so as to be connected to at least a part of the inlet opening  411  extending through the shielding member accommodation area  410 . In addition, the second conduit  413  may be formed in a direction different from that of the inlet opening  411 . For example, when the inlet opening  411  is formed in a first direction, the second conduit  413  may be formed in a second direction different from the first direction. For example, the second direction and the first direction may be vertical. 
     According to an embodiment, a second discharge conduit  414  may be formed at the end of the second conduit  413 . According to an embodiment, the second discharge conduit  414  may be provided as a space spaced between the support member  400  and the side wall  450 .

     Referring to  FIGS.  8  and  9   , the display module  330  may be attached to the support member  400 . According to an embodiment, the display module  330  may adhere onto the support member  400  through the adhesive member  490 . According to an embodiment, the display module  330  and the support member  400  may be combined to form the first conduit  415 . According to an embodiment, the display module  330  may adhere to the support member  400  through the adhesive member  490  so as to prevent sound from leaking to the outside through the first conduit  415 . In the above and below description of the specification, for the convenience of explanation, although only a combination of the support member  400  and the display module  330  is described, the concept of the disclosure may not be limited thereto. The display module  330  may be coupled to the front plate  320  so as to be coupled to the support member  400 , the front plate  320  and the support member  400  may be coupled to provide the duct structure  10 , and also it may be understood that various changes of embodiments are possible. 
     According to an embodiment, the display module  330  may be disposed on the auxiliary member  430 . In addition, the display module  330  may be disposed to be spaced apart from at least a part of the side wall  450  such that sound is emitted to the outside through the opening  432  (see  FIG.  6   ). For example, a space, in which at least a part of the display module  330  and the side wall  450  are spaced apart each other, may be configured to be provided as a sound charge conduit  415 . 
     According to an embodiment, the first conduit  415  may be formed between the display module  330  and the support member  400 . For example, a space between the display module  330  and the first surface  412   a  may be configured to be provided as the first conduit  415 . According to an embodiment, the first conduit  415  may be connected to the first discharge conduit  402 . 
     According to an embodiment, the first conduit  415  may be connected to the inlet opening  411 . For example, when the inlet opening  411  is formed to extend through the second surface  412   b  from the first surface  412   a  of the support member  400 , the first conduit  415 , which is formed between the display module  330  and the upper surface  412   b , may be connected to the inlet opening  411 . 
     According to an embodiment, the first conduit  415  and the second conduit  413  may be arranged side by side. For example, with reference to the first surface  412   a , the first conduit  415  may be formed above the first surface  412   a , and the second conduit  413  may be formed below the first surface  412   a . For example, the first conduit  415  and the second conduit  413  may be positioned in opposite directions with reference to the first surface  412   a.    
     According to an embodiment, the first conduit  415  and the second conduit  413  may be arranged in the same direction. In addition, the first conduit  415  and the second conduit  413  may be formed in a direction different from that of the inlet opening  411 . For example, when the inlet opening  411  is formed in a direction (e.g., a direction passing through the support member  400 ) from the first surface  412   a  toward the second surface  412   b , the first conduit  415  and the second conduit  413  may be formed in the width direction (or the length direction) of the support member  400 . According to an embodiment, the first conduit  415  and the second conduit  413  may be formed in a direction substantially perpendicular to the direction in which the inlet opening  411  is formed. 
       FIG.  10    is a view showing a sound path of a duct structure according to an embodiment of the disclosure. 
     The Y′-axis of  FIG.  10    may be interpreted as an axis parallel to the B-B′ axis of  FIG.  8   . 
     Referring to  FIG.  10   , the duct structure  10  may include the first conduit  415  and the second conduit  413 . All or a part of the configuration of the duct structure  10  of  FIG.  10    may be the same as or similar to the configuration of the duct structure  10  described in  FIGS.  5  to  9   , and thus overlapping descriptions will be omitted. According to an embodiment, sound emitted from the sound module  341  may be emitted to the outside through the first conduit  415  and the second conduit  413 . In the following description of the disclosure, the path of sound passing through the first conduit  415  may be referred to as a ‘first path R1’, and the path of sound passing through the second conduit  413  may be referred to as a ‘second path R2’. 
     According to an embodiment, sound emitted from the sound module  341  may be introduced into the inlet opening  411 . As described above, according to an embodiment, the inlet opening  411  may be connected to the accommodation portion  460 , and thus may be configured to receive sound emitted from the sound module  341  mounted in the accommodation portion  460 . 
     According to an embodiment, sound passing through the inlet opening  411  may be branched so as to pass through the first conduit  415  and the second conduit  413 . For example, sound introduced into the inlet opening  411  may enter each of the first conduit  415  and the second conduit  413  which are branched with reference to a portion  405  of the second surface  412   b . For example, sound emitted from the sound module  341  may travel to the inlet opening  411  which is a common path, and then may be branched to be delivered to the first path R1 and the second path R2. For example, it may be also expressed that the first path R1 and the second path R2 have a common path with respect to the first direction (the +Z-axis direction) in at least a part of the inlet opening  411 , and are branched in the second direction (the +Y′-axis direction) in the inlet opening  411 . 
     According to an embodiment, the first path R1 and the second path R2 may be combined in the sound output conduit  404   a . For example, sounds, which are branched to the first path R1 and the second path R2 and then travels, may overlap each other in the sound output conduit  404   a , and then may be delivered to the outside through one path. 
       FIG.  11    is a view showing the length of a sound conduit according to an embodiment of the disclosure. 
     The Y′-axis of  FIG.  11    may be interpreted as an axis parallel to the B-B′ axis of  FIG.  8   . 
     Referring to  FIG.  11   , the lengths of the first path R1 and the second path R2 may be formed to satisfy a predetermined condition. For example, the predetermined condition may be determined by the wavelength or frequency of sound emitted from the sound module  341 . 
     According to an embodiment, the first path R1 and the second path R2 may have lengths corresponding to each other. For example, the first path R1 and the second path R2 may have a substantially identical length or similar lengths. Since the first path R1 and the second path R2 have lengths corresponding to each other, sound quality may be improved when sound passing through the first path R1 and the second path R2 are added. 
     According to an embodiment, the distance l1 (hereinafter, referred to as a ‘first vertical distance’) from the sound module  341  to the first conduit  415  in the first direction (e.g., the +Z-axis direction) may be configured to correspond to the distance l2 (hereinafter, referred to as a ‘second vertical distance’) from the sound module  341  to the second conduit  413  in the first direction and the distance l3 (hereinafter, referred to as a ‘third vertical distance’) from the second conduit  413  to the first conduit  415  in the first direction. In addition, according to an embodiment, the length r1 (hereinafter, referred to as a ‘first horizontal distance’) of the first conduit  415  in the second direction (e.g., the x-axis direction) may be configured to correspond to the length r2 (hereinafter, referred to as a ‘second horizontal distance’) of the second conduit  413  in the second direction (e.g., the x-axis direction). For example, the first vertical distance l1 may be configured to correspond to the sum of the second and third vertical distances l2 and l3, and the first horizontal distance r1 and the second horizontal distance r2 may be configured to correspond to each other. Therefore, the travel distances of sound passing through the first path R1 and the second path R2 may correspond to each other. As the travel distances of sound passing through the first path R1 and the second path R2 correspond to each other, when each sound overlaps, sounds having substantially the same wavelength band or similar wavelength bands may overlap each other so that the quality of sound emitted to the outside is improved. As another example, the difference in length between the first path R1 and the second path R2 may be configured to be related to the wavelength of sound emitted from the sound module  341 . 
     According to an embodiment, sound passing through the first path R1 and the second path R2 may be added in the sound output conduit  404   a , and then may be output to the outside. 
       FIGS.  12 A to  12 C  illustrate a part of a duct structure according to various embodiments of the disclosure. 
     Referring to  FIGS.  12 A to  12 C , a support member  1000  may include an inlet opening  1011 , a shielding member  1020 , and an auxiliary member  1030   a ,  1030   b , or  1030   c.    
     All or a part of the configuration of the support member  1000 , the inlet opening  1011 , the shielding member  1020 , and the auxiliary member  1030   a ,  1030   b , or  1030   c  of  FIGS.  12 A to  12 C  may be the same as or similar to the configuration of the support member  400 , the inlet opening  411 , the shielding member  420 , and the auxiliary member  430  of  FIGS.  5  to  9   , and thus overlapping descriptions will be omitted. 
     According to various embodiments, the size of a first discharge conduit  1002   a ,  1002   b , or  1002   c  may be various. For example, the shape and size of the first discharge conduit  1002   a ,  1002   b , or  1002   c  may be determined. According to an embodiment, the support member  1000  may have multiple numbers of support portions  1003   b  or  1003   c  formed therein. 
     According to various embodiments, the support portion  1003   b  or  1003   c  may have a changeable number or may not be formed. For example, when the first discharge conduit  1002   a  is configured to have a small size, the support portion may not be formed. As another example, when the first discharge conduit  1002   c  is configured to have a relatively large size, multiple support portions  1003   c  may be formed. 
     According to an embodiment, as the size of the first discharge conduit  1002   a ,  1002   b , or  1002   c  increases, the area of the auxiliary member  1030   a ,  1030   b , or  1030   c  disposed on the first discharge conduit  1002   a ,  1002   b , or  1002   c  may be increased. In the case, in order to prevent deformation of the auxiliary member  1030   a ,  1030   b , or  1030   c  due to the load thereof, the support portion  1003   b  or  1003   c  may be formed, and as the size of the first discharge conduit  1002   b  or  1002   c  increases, a larger number of the support portions  1003   b  or  1003   c  may be formed. In addition, since the deformation of the auxiliary member  1030   a ,  1030   b , or  1030   c  is prevented, it may be possible to prevent foreign materials from entering an opening  1032   a ,  1032   b , or  1032   c  or the first discharge conduit  1002   a ,  1002   b , or  1002   c.

For example, after a support member  1100   a  is shaped, a support member  1100   e , with which an auxiliary member is integrated, may be provided by performing an additional process on the support member  1100   a . All or a part of the configuration of each of support members  1100   a ,  1100   b ,  1100   c ,  1100   d , and  1100   e  of the  FIGS.  13 A to  13 F  may be the same as that of the support member  311  of the  FIG.  4   . In addition,  FIGS.  13 A to  13 F  show a processing process which may be performed on the duct area A of  FIG.  4   .

     Referring to  FIGS.  13 D and  13 E , after the first discharge conduit  1102   c  is formed, a shielding member  1120  may be attached thereto (e.g., the support member  1100   d  to which the shielding member  1120  is attached). In addition, an adhesive member  1190  may be disposed (e.g., the support member  1100   e  on which the adhesive member  1190  is disposed). All or a part of contents related to the shielding member  1120  or the adhesive member  1190  may be the same as or similar to the contents of the shielding member  420  or the adhesive member  1190  of  FIGS.  5  and  6   , and thus overlapping descriptions will be omitted. 
     Referring to  FIGS.  13 E and  13 F , after the adhesive member  1190  is applied, the display module  330  may be attached to the support member  1100   e .
