According to an embodiment, the second circuit board255may be electrically connected to the external microphone242. For example, the external microphone242may be disposed in one area of the second circuit board255to correspond to the position of the microphone hole221of the second case220. For example, the first circuit board252and the second circuit board255may be at least one of a printed circuit board (PCB) and a flexible printed circuit board (FPCB).

The connection part256may electrically connect the first circuit board252and the second circuit board255. According to an embodiment, the connection part256may surround a part of the sidewall of the battery251and extend from the first circuit board252to the second circuit board255. The connection part256may be, for example, at least one of a flexible printed circuit board (FPCB) formed of a polyimide material and a metal wire.

The nozzle300may connect the inner space201of the case200to the outside of the wearable device100. According to an embodiment, the nozzle300may be coupled to the case200by being inserted into the through hole213. For example, the nozzle300may be coupled to the case200such that a part of the nozzle300is located inside the case200and the other part of the nozzle300is located outside the wearable device100. The other part of the nozzle300may be inserted into the user's external auditory meatus when the wearable device100is worn on the user. According to an embodiment, the nozzle300may be rotatably coupled to the case200. For example, the nozzle300may be coupled to the case200to be rotatable along the periphery of the through hole213. According to an embodiment, at least a portion of the cross section of the nozzle300may have a shape corresponding to the cross section of the through hole213. For example, the cross section of the through-hole213may be circular, and the cross section of a part of the nozzle300in contact with the through-hole213may be circular. Since the cross section of the nozzle300and the cross section of the through hole213have a shape corresponding to each other, the nozzle300may have a coaxial axis with the through hole213and rotate based on the through hole213.

According to an embodiment, the nozzle300may include a tube320and a fastening portion330. The audio path310formed by the tube320may transmit sound or signal output from the speaker230to the outside of the wearable device100. For example, the audio path310may extend from the inner space201toward the outside of the wearable device100. Audio output from the speaker230may pass through the audio path310of the nozzle300in the inner space201and may be transmitted to the outside of the wearable device100.

According to an embodiment, the nozzle300may be formed of a plurality of pieces. For example, the nozzle300may be formed of two pieces coupled to each other. The two pieces coupled to each other may form a tube320and a fastening portion330, respectively.

The tube320may be an acoustic transmission duct that transmits sound or signal output from the speaker230to the outside or transmits sound or signal introduced from the outside to the microphone240. At least a portion of the tube320may be exposed to the outside of the first case210.

The fastening portion330may be configured to couple the ear tip400and the nozzle300. According to an embodiment, the fastening portion330may be a protrusion to which the ear tip400is fastened and may have a shape corresponding to a fastening groove (not illustrated) formed inside the ear tip400. According to an embodiment, the fastening portion330may be coupled to one end of the tube320exposed to the outside of the first case210.

According to an embodiment, the thickness of the fastening portion330may be 0.5 mm or less. For example, when the nozzle300is formed through insert injection, the thickness of the fastening portion330may be 0.05 mm to 1 mm. When the thickness of the fastening portion330decreases, the size of the wearable device100may decrease.

According to an embodiment, the fastening portion330and the first case210may be disposed to be spaced apart from each other. The separation distance r, which is a distance between the fastening portion330and the first case210, may affect the performance of the microphone240. For example, as the separation distance r decreases, the performance of the microphone240may be improved. When the first case210and the nozzle300are integrally manufactured, the separation distance r may unnecessarily increase. For example, when the first case210including the nozzle300is integrally formed, the separation distance r may increase by the minimum thickness capable of forming the mold. When the separation distance r increases, the length of the audio path310extending from the microphone240along the tube320may increase, so that the performance of the microphone240may be deteriorated, and the wearing comfort may be reduced. According to an embodiment, the first case210and the nozzle300of the wearable device100may be separately manufactured to prevent and/or reduce unnecessary increase in the separation distance r. For example, the first case210and the nozzle300may be separately manufactured. When the nozzle300is manufactured by inserting the tube320inside the first case210, the separation distance r may be set to secure the performance of the microphone240. Since the separation distance r is prevented/reduced from increasing, the wearable device100may secure excellent performance of the microphone240.

The ear tip400may be coupled to a part of the nozzle300exposed to the outside of the case200. When the wearable device100is worn to the user, the ear tip400may be in close contact with the inner wall of the external auditory meatus so that the audio output by the speaker230is smoothly transmitted to the user. In an embodiment, the ear tip400may be formed of a silicon material. For example, at least one area of the ear tip400may be deformed according to the shape of the user's ear when the wearable device100is worn on the user. For example, the ear tip400may be formed of a combination of at least one of silicon, foam, and plastic.

According to an embodiment, the wearable device100may improve a user's wearing comfort by including a nozzle300rotatably coupled to the first case210so as to be suitably worn on the user's ear. For example, when the nozzle300is coupled to the case200so as not to be movable, since the shape of the ear is different for each user, the user may not be able to adjust the nozzle300to suit his or her ear. According to an embodiment, when the nozzle300is rotatably coupled to the case200, the wearable device100may improve a user's wearing comfort by adjusting the nozzle300.

FIG.2Ais a cross-sectional view illustrating an example taken along line A-A′ ofFIG.1Bin a state in which the first case and the nozzle of the wearable device are fastened, andFIG.2Bis a top view illustrating a state in which a first case and a nozzle of a wearable device are fastened.

Referring toFIGS.2A and2B, according to an embodiment, the first case210forming the appearance of the wearable device100(e.g., the wearable device100ofFIG.1A) may be rotatably coupled to the nozzle300. For example, the nozzle300may be inserted into the through hole213and coupled to the first case210so that a part300A of the nozzle300is located in the inner space201.

According to an embodiment, a part300A of the nozzle300positioned in the first case210may have a shape of a flange340. The flange340may be disposed on the seating portion260and supported by the seating portion260. For example, the flange340may be formed to extend from the end of the nozzle300in the radial direction of the through hole213. When assembling the wearable device100, the nozzle300may be assembled to protrude from the inner space201to the outside of the first case210through the through hole213of the first case210. When the nozzle300is assembled to protrude from the inner space201to the outside of the first case210, the flange340may determine an external protruding length of the nozzle300and prevent/inhibit the nozzle300from being separated from the outside of the first case210.

According to an embodiment, the size of the flange340may be larger than the size of the through hole213so that the nozzle300is not separated from the first case210. For example, the outer diameter of the flange340may be equal to or larger than the inner diameter of the through hole213. The outer diameter of the tube320may be smaller than the inner diameter of the through hole213in consideration of an error such as a manufacturing tolerance. The outer diameter of the flange340may be larger than an inner diameter of the through hole213. Since the outer diameter of the flange340is manufactured to be larger than the inner diameter of the through hole213, the flange340may be seated on the seating surface of the seating portion260. The nozzle300inserted into the through hole213may rotate along the periphery of the through hole213. For example, the nozzle300may rotate clockwise or counterclockwise with respect to the first case210along the periphery of the through hole213. The cross section of the through hole213may be formed in a circular shape, and the cross section of the nozzle300may be manufactured in a circular shape to move along the through hole213.

According to an embodiment, the first case210may include a seating portion260and a guiding portion270. The seating portion260may support the flange340of the nozzle300positioned within the first case210. According to an embodiment, the seating portion260may be a part of the first case210formed along the periphery of the through hole213. For example, the seating portion260may have a seating surface extending from a periphery of the through hole213in a radial direction of the through hole213.

The guiding portion270may be disposed on the seating portion260and guide the rotation of the nozzle300. According to an embodiment, the guiding portion270may include a guiding protrusion271protruding from a seating surface of the seating portion260in contact with the flange340of the nozzle300.

According to an embodiment, the nozzle300may include a guiding groove350. The guiding groove350may accommodate the guiding protrusion271and guide rotation of the nozzle300. In an embodiment, the guiding groove350may be formed in the flange340of the nozzle300located in the first case210. For example, the guiding groove350may be an empty space formed in the flange340surrounded by the sidewall360. As the guiding groove350is formed in the flange340, the guiding groove350may rotate together with the nozzle300. As the guiding groove350rotates together with the nozzle300, the position of the guiding protrusion271in the guiding groove350may be changed. According to an embodiment, the guiding groove350may form a coaxial with the through hole213so that the nozzle300rotates with respect to the axis of the through hole213. For example, the rotation center of the guiding groove350may be the rotation center of the nozzle300. The rotation axis of the nozzle300may pass through the center of a circle that is a cross section of the through hole213. Since the rotation axis of the nozzle300passes through the center of a circle that is the cross-section of the through-hole213, and the cross-section of the nozzle300and the through-hole213is circular, the nozzle300inserted into the through-hole213may rotate.

According to an embodiment, the guiding groove350may extend along a part of a periphery of the through hole213. For example, the guiding groove350may be in the form of an arc extending between one end350aand the other end350b. The guiding groove350may extend by a distance requiring fine adjustment of the nozzle300. According to an embodiment, both end portions350aand350bof the guiding groove350may limit the rotation angle of the nozzle300. For example, when the nozzle300rotates clockwise, the guiding groove350may change the position of the guiding protrusion271in a direction toward one end350aof the guiding groove350. When the guiding protrusion271is in contact with one end350aof the guiding groove350, one end350aof the guiding groove350may function as a stopper for preventing/reducing rotation of the nozzle300rotating in the clockwise direction. For another example, when the nozzle300rotates counterclockwise, the guiding groove350may change the position of the guiding protrusion271in a direction toward the other end350bof the guiding groove350. When the guiding protrusion271is in contact with the other end350b, the other end350bof the guiding groove350may function as a stopper for preventing and/or reducing rotation of the rotating nozzle300.

According to the above-described embodiment, the wearable device100may include a nozzle300rotatably coupled to the first case210to be suitably worn on the user's ear, thereby improving the user's wearing comfort. The wearable device100may prevent/inhibit the nozzle300from spinning with out of a designated range by providing a guiding groove350for limiting the rotation radius of the nozzle300.

FIG.3is a diagram illustrating an example of a nozzle including a positioning protrusion according to an embodiment. The first case210and the nozzle300ofFIG.3may be the first case210and the nozzle300in which the structures of the first case210and the nozzle300ofFIGS.1A,1B,2A, and/or2B are changed, and descriptions thereof may not be repeated here.

Referring toFIG.3, according to an embodiment, the guiding groove350may include a positioning protrusion370.

The positioning protrusion370may interfere with rotation of the nozzle300to provide a click feeling to a user rotating the nozzle300. According to an embodiment, the positioning protrusion370may protrude from one of a plurality of sidewalls361and362spaced apart from each other toward the other sidewall360. For example, the positioning protrusion370may protrude from the first sidewall361adjacent to the audio path310toward the second sidewall362facing the first sidewall361. For another example, the positioning protrusion370may protrude from the second sidewall362toward the first sidewall361facing the second sidewall362.

According to an embodiment, the positioning protrusion370may include a plurality of positioning protrusions371,372,373, and374. For example, a plurality of positioning protrusions371,372,373, and374may be disposed to be spaced apart from each other along the first sidewall361. The guiding protrusion271may be located in one space among the spaces between a plurality of positioning protrusions371,372,373, and374.

According to an embodiment, a plurality of positioning protrusions371,372,373, and374may move the guiding protrusion271positioned in one space among the spaces between the plurality of positioning protrusions371,372,373, and374to the another space between the plurality of positioning protrusions371,372,373, and374by the rotation of the nozzle300. For example, when the nozzle300rotates clockwise, the position of the guiding protrusion271may be changed from a space between the first positioning protrusion371and the second positioning protrusion372to a space between the second positioning protrusion372and the third positioning protrusion373. For another example, when the nozzle300rotates counterclockwise, the position of the guiding protrusion271may be changed from a space between the first positioning protrusion371and the second positioning protrusion372to a space between the first positioning protrusion371and the fourth positioning protrusion374.

According to an embodiment, the protrusion formed on the first sidewall361and the protrusion formed on the second sidewall362may be disposed on the first sidewall361and the second sidewall362, respectively, to face each other. A space in which the guiding protrusion271can move may be formed between the protrusion formed on the first sidewall361and the protrusion formed on the second sidewall362disposed to face each other.

According to an embodiment, although the positioning protrusion370has been described as a plurality of positioning protrusions371,372,373and374, there may be only one positioning protrusion370. For example, the positioning protrusion370may be disposed inside the guiding groove350and may be move the guiding protrusion271in a space positioned on one side surface of the positioning protrusion370or a space positioned on the other side surface opposite to one side surface of the positioning protrusion370. The guiding protrusion271may flow finely in a space located on one side surface of the positioning protrusion370or a space located on the other side surface of the positioning protrusion370.

According to an embodiment, the positioning protrusion370has been described as positioned on both the first sidewall361and the second sidewall362and described as being disposed in a shape corresponding to each other but is not limited thereto. For example, the positioning protrusion370may be disposed on one of the first sidewall361or the second sidewall362. For another example, a part of the positioning protrusions may be disposed on a part of the first side wall361, and the other part of the positioning protrusions may be disposed on the second side wall362facing the other part of the first side wall361.

According to an embodiment, the positioning protrusion370may be made of an elastically deformable material. For example, the positioning protrusion370may be made of at least one material selected from rubber, polyurethane, or a combination thereof.

According to the above-described embodiment, the wearable device100may provide a click feeling to a user rotating the nozzle300by including a positioning protrusion370that may interfere with rotation of the nozzle300. The user may intuitively grasp the degree of rotation of the nozzle300by the click feeling provided by the positioning protrusion370. The wearable device100may fix the nozzle300at a designated position in the guiding groove350to maintain the position of the nozzle300while the user is wearing the wearable device100.
