       FIG.  5 A  is a partial cut away perspective view illustrating a part of the wearable device of  FIG.  3    taken along line A-A′.  FIG.  5 B  is a perspective view viewing a first housing of a wearable device according to various embodiments of the disclosure.  FIG.  6    is an example view schematically illustrating a first and a second path, a speaker, and a microphone arrangement status of a wearable device according to various embodiments of the disclosure.

     According to an embodiment, the speaker  20  may include a diaphragm, an acoustic generation part, and a coil (not illustrated). According to an embodiment, the speaker  20  is disposed in the housing  13  to generate sound in the first direction {circle around ( 1 )}, and the generated sound may move towards the outside of the first housing  11  through the first path  41  along an arrow direction  411 . According to an embodiment, when the diaphragm of the speaker  20  vibrates, a part of speaker sound moving toward the second direction {circle around ( 2 )} opposite to the first direction {circle around ( 1 )} may be output to the outside through the first port  114  or the second port  124  (shown in  FIG.  2   ). According to an embodiment, the sound output from the speaker  20  may move in the first direction {circle around ( 1 )} through the first path  41  from one or more resonance space(s) to be output to the outside through the speaker nozzle part  112  (e.g., in arrow direction  411 ), and a part of sound which fails to be output to the outside through the first path  41  may move in the second direction {circle around ( 2 )} to be output to the outside through the first port  114 . 
     According to an embodiment, a microphone  22  is an electronic component for collecting a sound signal introduced from the outside into the housing  13 , and at least one thereof may be disposed in the housing  13 . In some embodiments, the microphone  22  may be a feedback microphone. According to an embodiment, a feedback microphone may be a microphone for removing outside noise by comparing the sound output from the speaker  20  of the wearable device  10  and sound introduced from the outside of the wearable device  10  when the wearable device  10  performs an ANC operation. According to an embodiment, the microphone  22  may be disposed at a location spaced apart from the speaker  20  and disposed at a location spaced apart from the partition wall  30 . In some embodiments, the partition wall  30  may be located between the microphone  22  and the speaker  20 . 
     According to an embodiment, a resonance space “s” may be located in the first direction {circle around ( 1 )} of the speaker  20 . The partition wall  30  may be located between the resonance space “s” and the second path  42  and provided to allow a sound from the speaker  20  to be input to the microphone  22 . According to an embodiment, the partition wall  30  may be made by a separate member and attached to an inner support member  221  to provide or define the second path  42 . According to an embodiment, the partition wall  30  and the inner support member  221  may be integrally formed. According to an embodiment, the thickness of the partition wall  30  may be different from the thickness of the inner support member  221 . 
     According to an embodiment, an additional resonance space may be further included in the second direction {circle around ( 2 )} of the speaker  20 . For example, an additional resonance space (not illustrated) may be located in the second direction {circle around ( 2 )} of the diaphragm of the speaker  20 . 
     According to an embodiment, the first path  41  may be provided between the speaker nozzle part  112  and the speaker  20 . According to an embodiment, the first path  41  is a path through which speaker sound which is the sound generated from the speaker  20  to be output to the outside by passing through the speaker nozzle part  112  passes, and may be provided as a duct structure  140  (e.g., as illustrated in  FIG.  6   ). According to an embodiment, the first path  41  may be provided in the inner support member  221 , for example, an inner support frame or a bracket, of the housing  13 . According to an embodiment, the first path  41  may face the first direction {circle around ( 1 )}. In some embodiments, the first path  41  may have a linear shape or a curved shape, or a combination thereof. 
     According to an embodiment, the second path  42  may diverge from the first path  41  and may be provided between the first path  41  and the microphone  22 . According to an embodiment, the second path  42  is a path through which a sound signal introduced through the first path  41  reaches the microphone  22  passes, and may be provided as a duct structure  142 . According to an embodiment, the second path  42  may be provided in a part of the inner support member  221 , for example, an inner support frame or a bracket, of the housing. According to an embodiment, the second path  42  may include a third path  422  diverging from the first path  41 , and a fourth path  443  extending from the third path  442  and directing a sound signal moved through the third path  422  to the microphone  22 . That is, the second path  42  may be formed or defined by two portions  422 ,  433 , with the third path  422  (of the second path  42 ) extending between the first path  41  and the second portion of the second path  42  (i.e., fourth path  423 ), and the fourth path  423  extends from the third path  422  and is arranged to direct sound toward the microphone  22 . In some embodiments, the third path  422  and the fourth path  423  may be arranged in different directions. 
     According to an embodiment, the second path  42  may diverge from the first path  41 , and a cross sectional size of the second path  42  (e.g., d 3  and/or d 4 ) may be smaller than a cross sectional size of the first path  41  (e.g., d 1  and/or d 2 ). That is, the cross-sectional dimensions of the second path  42  (and each of third path  422  and fourth path  423  thereof) is less than the cross-sectional dimensions of the first path  41 . 
     According to an embodiment, when it is defined that a distance (e.g., a width) between a first surface  140   a  of the duct structure  140  defining the first path  41  and one end part  302  of the partition wall  30  is a first distance d 1  and a distance (e.g., a width) between the first surface  140   a  of the duct structure  140  and a second surface  140   b  of the duct structure  140  in a direction facing the first surface  140   a  is a second distance d 2 , the first distance d 1  may be substantially equal to or larger than the second distance d 2 . According to an embodiment, when a distance between a third surface  30   a  of the duct structure  142  defining the third path  422  and a fourth surface  30   b  of the duct structure  142  in a direction facing the third surface  30   a  is a third distance d 3 , the third distance d 3  may be smaller than each of the first distance d 1  and the second distance d 2 . According to an embodiment, when a distance between a fifth surface  142   a  of the duct structure  142  defining a fourth path  423  and a sixth surface  142   b  of the duct structure  142  in a direction facing the fifth surface  142   a  is a fourth distance d 4 , the fourth distance d 4  may be smaller than each of the first distance d 1  and the second and d 2 . 
     According to an embodiment, the third path  422  may be approximately perpendicular to the first direction {circle around ( 1 )}, and the fourth path  423  may be approximately perpendicular to the third path  422  and face the first direction {circle around ( 1 )}. For example, the third path  423  may be substantially parallel to the first path  41 , and may be oriented in the first direction {circle around ( 1 )}. 
     According to an embodiment, the speaker sound output from the speaker  20  though the first path  41  may move in the first direction {circle around ( 1 )} and may be output to the outside of the wearable device  10 . Additionally, a sound signal (or an external sound) may be introduced in the second direction {circle around ( 1 )} from the outside of the wearable device  10 . According to an embodiment, at least a part of the first path  41  may share at least a part of a path from which the speaker sound output from the speaker  20  is output and a path through which a sound signal outside the wearable device  10  is introduced into the microphone  22 . Therefore, at least a part of the sound signal introduced into the housing  13  through the speaker nozzle part  112  may pass through a part of the first path  41 , move toward the second path  42 , and be finally collected in the microphone  22 . 
     According to an embodiment, the partition wall  30  may be a member for spatially partitioning a mounting space of the speaker  20  and a mounting space of the microphone  22 , and may extend (internally) from a part of the housing  13  toward the first path  41 . According to an embodiment, the partition wall  30  may be a member for spatially partitioning the second path  42  provided to allow a sound to be input to a speaker resonance space “s” and the microphone  22  (e.g., as shown in  FIG.  5 A ). The partition wall  30  may extend from a part of the housing  13  toward the first path  41 . According to an embodiment, the partition wall  30  may be formed as an injection structure for spatially partitioning the first path  41  and the second path  42 . For example, in some embodiments, the partition wall  30  may be integrally inj ection-molded as a part of the housing  13 , or in other embodiments, the partition wall  30  may be made of a separate material to be coupled to the housing  13 . In some non-limiting embodiments, the partition wall  30  may have a thin plate shape. According to an embodiment, the partition wall  30  may be coupled to a part of a support member of the first housing  11  or a part of a support member of the second housing  12  through an adhesive, bonding, mechanical coupling, or the like. 
     According to an embodiment, the partition wall  30  may protrude from the inner support member (e.g., a support frame or a bracket) of the housing  13  toward the first path  41 , and may extend to a length in which the end part  302  of the partition wall  30  does not protrude within the first path  41 . For example, the first distance dl between the end part  302  and the first surface  140   a  of the first path  41  may be substantially identical to the second distance d 2  between the first surface  140   a  of the first path  41  and the second surface  140   b  of the first path  41 . In accordance with some embodiments, the end part  302  of the partition wall  30  may extend into the first path  41  in a protruding shape and a partial area of the first path  41  may be blocked to cause an obstacle to outputting speaker sound from the speaker  20 . 
     According to an embodiment, the partition wall  30  may be disposed to be approximately parallel to the speaker  20  and disposed to be approximately parallel to the microphone  22 . That is, an orientation of the partition wall  30  may be such that it provides a wall or barrier between the speaker  20  and the microphone  22 . 
     According to an embodiment, the microphone  20  may be disposed at a part of the inner support structure  221  of the housing  13  while at least a part thereof is wound or enclosed by a microphone sealing member  220 . According to an embodiment, the microphone sealing member  220  may elastically support a mounting structure of the microphone  20  and may seal the microphone  20  from the outside. 
     According to an embodiment, a microphone hole  2201  may be provided through the microphone sealing member  220  to provide a path for sound to travel from the fourth path  423  and interact with the microphone  22 . 
     According to an embodiment, when the first housing  11  and the second housing  12  are assembled, an adhesive member  224  (e.g., shown in  FIG.  5 A ) may be attached between a part of a support member  222  of the first housing  11  and a part of the support member  221  of the second housing  12 , in order to define a part of the second path  42 . The adhesive member  224  may be formed from rubber tape or the like. According to an embodiment, the adhesive member  224  may be disposed on a boundary part of the first housing  11  and the second housing  12  to seal at least a part of the duct structure  142  defining the second path  42 . 
     Referring to  FIG.  7   , a partition wall  32  according to an embodiment may be made by a separate member to be attached to a portion of the housing  13  (e.g., a part of second housing  12 ). According to an embodiment, the partition wall  32  may be separately manufactured to be attached, coupled, or injection-molded to the inner support member  221  which is a part of the second housing  12 . In accordance with some embodiments of the present disclosure, a material of the partition wall  32  may be different from a material of the inner support member  221 . 
     Referring to  FIG.  8 A , a second path  43  according to an embodiment may diverge from the first path  41 , face a direction perpendicular to the first path  41 , be provided by a linear duct structure  143 , and extend in a direction facing the microphone  22 . According to an embodiment, the microphone  22  may be disposed to frontally and directly face the second path  43 . According to an embodiment, a sound signal moved through the second path  43  may be collected in the microphone  22  through the microphone hole  2201 . According to an embodiment, a direction in which the sound signal output from the speaker  20  may be substantially perpendicular to a direction in which the sound signal moves toward the microphone  22 . 
     Referring to  FIG.  8 B , the second path  44  according to an embodiment may be defined by a duct structure  144 , and may include a third path  441  diverging in a direction inclined from the first path  41 , a fourth path  442  linearly extending from the third path  441 , and a fifth path  443  extending in a right-angle direction from the fourth path  442  to be connected with the microphone  22 . According to an embodiment, a sound signal having passed through the fifth path  443  may be collected in the microphone  22  through the microphone hole  2201 . For example, the third path  441  diverging from the first path  41  may include an inclination to reduce an introduction of the sound, which is output from the speaker  20  and moves in a first direction, into the second path  44 . That is, the third path  441  may be angled to preferentially receive sound received from the second direction {circle around ( 2 )}, and to minimize sound traveling in the first direction {circle around ( 1 )}. 
     Referring to  FIG.  8 C , a second path  45 , according to an embodiment, diverges from the first path  41  and may be defined by a duct structure  145  which extends in a curved shape. In the illustrative configuration, the second path  45  has the letter “C” shape, contour, or curvature, in which one end thereof may be spatially connected to the first path  41  and the other end thereof may be connected to the microphone hole  2201 . According to an embodiment, a sound signal having passed through the second path  45  may be collected in the microphone  22  through the microphone hole  2201 . Similar to the configuration of  FIG.  8 B , the second path  45  of  FIG.  8 C  may be angled or oriented to preferentially receive sound received from the second direction {circle around ( 1 )}, and to minimize sound traveling in the first direction {circle around ( 1 )}. The curvature of the second path  45  may be configured to direct sound from the first path  41  to the microphone  22  in a substantially smooth or continuous curve. In other embodiments, the second path  45  may include a substantially straight portion between two curved ends (e.g., a first curved end proximate the first path  41  and a second curved end proximate the microphone  22 ). 
     Referring to  FIG.  9   , according to an embodiment, when the first housing  11  and the second housing (not shown in  FIG.  9   ) are assembled, a boundary part between the first housing  11  and the second housing may block an outside sound signal introduction by a bonding process. For example, in  FIG.  9   , reference signals BLO and BL 1  may be an adhesive layer (e.g., an adhesive member). The adhesive layers/members BL 0 , BL 1  may be arranged to provide a seal between the first housing  11  and the second housing, or a bracket assembly  14 , as shown in  FIG.  9   . The bracket assembly  14  may be housed within or between the first housing  11  and the second housing. 
     According to an embodiment, the bracket assembly  14  to which at least one component (e.g., the speaker  20 , the microphone  22 , or a battery (not illustrated)) of the wearable device  10  is assembled may be attached to the first housing  11  (e.g., as shown in  FIG.  9   ). The first housing  11  and the second housing  12  may then be bonded together, with the adhesive layers/members BL 0 , BL 1  providing bonding and sealing between the components of the wearable device  10 . The resonance space “s” of the speaker  20  and the microphone  22  are spatially separated by the partition wall  30 , so that the first path  41  and the second path  42  may be defined. The duct structure of the second path  42  may be secured by the adhesive member  224  (e.g., silicon rubber) disposed between the inner support members (e.g., the bracket assembly  14 ) of the first housing  11  and/or the second housing  12  (e.g., as shown in  FIGS.  5 A,  7   ). In accordance with some embodiments, the first housing  11 , the second housing  12 , and/or the bracket assembly  14  may be coupled by a bonding process, so that the outside sound signal fails to pass through the second path  42  and introduction thereof into the microphone  22  through another gap may be reduced. 
     Referring to  FIG.  10   , the wearable device  10  according to an embodiment may include the housing  13 , the speaker  20 , the microphone  22 , a first path  410 , a second path  420 , a first space sl and a second space s 2 , and a partition wall  30 . 
     According to an embodiment, the first space sl may be defined between the speaker  20  and the partition wall  30 , and the second space s 2  may be defined between the partition wall  30  and the microphone  22 . In accordance with some embodiments, at least a part of the first space sl may be a resonance space of the speaker  20 , and at least a part of the second space s 2  may be a space through which the collected acoustic signal passes. 
     According to an embodiment, the first path  410  may be a path between the first space sl and the speaker nozzle part  112 , and the second path  420  may be a path between the speaker nozzle part  112  and the second space s 2 . According to an embodiment, at least a part of the first path  410  and the second path  420  may include the same path, and at least a part thereof may be a shared path. 
     According to an embodiment, a first acoustic signal output from the speaker  20  may pass along the first path  410  and may be output to the outside of the speaker nozzle part  112 , and a second acoustic signal may be input to the microphone  22  along the second path  420  by which the microphone  22  and the speaker nozzle part  122  are connected.
