The terminal 253 may be exposed to the outside of the first case 210 through the terminal hole 211. According to an embodiment, the first housing 210 may include a sensor hole 212 that communicates the wear detection sensor 254 with the outside of the wearable device 100. The wear detection sensor 254 may be a sensor capable of collecting information capable of detecting the wear of the user. The wear detection sensor 254 may be exposed to the outside of the first housing 210 through the sensor hole 212. According to an embodiment, the first housing 210 may include a through hole 213 that communicates the inner space 201 with the outside of the wearable device 100.

The second housing 220 may be disposed to face a direction opposite to the disposition direction of the first housing 210 with respect to the boundary surface between the first housing 210 and the second housing 220 when the wearable device 100 is worn by a user. According to an embodiment, a microphone hole 221 communicating the inner space 201 in which the microphone 240 is disposed with the outside of the wearable apparatus 100 may be formed at one side of the second case 220. According to an embodiment, the second housing 220 may include a touch area configured to detect a user touch.

The microphone 240 may receive an audio signal and generate an electrical signal based on the received audio signal. For example, microphone 240 may obtain audio information for transmission through mouthpiece 300. As another example, microphone 240 may be an Active Noise Cancellation (ANC) feedback microphone for canceling noise. According to an embodiment, the microphone 240 may include an inner microphone 241 disposed to face the first housing 210 and an outer microphone 242 disposed to face the second housing 220. For example, the microphone 240 may be an Electronic Capacitive Microphone (ECM) or a microelectromechanical system (MEMS), but is not limited thereto.

The electronic assembly 250 may include electrical circuitry internal to the wearable device 100. According to an embodiment, the electronic assembly 250 may include a battery 251, a first circuit board 252, terminals 253, a wear detection sensor 254, a second circuit board 255, and a connection 256.

The battery 251 may supply power to at least one component of the wearable device 100. According to an embodiment, the battery 251 may include, for example, a primary battery that is not rechargeable, a rechargeable secondary battery, or a fuel cell.

The first circuit board 252 may be disposed adjacent to the first housing 210. According to an embodiment, the first circuit board 252 may be electrically connected to the speaker 230 and the internal microphone 241. According to an embodiment, a terminal 253 electrically connecting the battery 251 and the external electronic device may be provided on the first circuit board 252. The terminal 253 may be disposed on the first circuit board 252 such that a portion of the terminal 253 passes through the terminal hole 211 formed in the first housing 210 and is exposed to the outside of the wearable device 100. For example, the external device connected to the wearable device 100 through the terminal 253 may be a cradle (not shown) for supplying power to the battery 251. The terminal 253 may be connected to a terminal of an external device such as a cradle (such as a charging device or a charging housing of a wearable device). The terminal 253 may supply power to the wearable device 100 through a terminal of an external electronic device. For example, the power supplied to the wearable device 100 may be used to charge the battery 251. The terminal hole 211 may be formed on a side surface of the wearable device 100 facing the mounting surface of the external device when the wearable device 100 is mounted on the external device. For example, when the wearable device 100 is disposed in a state specified in the charging housing of the wearable device 100, the terminal hole 211 may be formed at a position corresponding to the charging terminal among surfaces of the wearable device 100 that contact the charging housing. According to an embodiment, a wear detection sensor 254 configured to detect whether the user wears the wearable apparatus 100 may be provided on the first circuit board 252. The wear detection sensor 254 may be disposed on the first circuit board 252 such that a portion passes through the sensor hole 212 formed in the first housing 210 and is exposed to the outside of the wearable device 100. The wear detection sensor 254 may detect contact or touching of a portion of the user's body. For example, the wear detection sensor 254 may detect when the wearable device 100 is inserted into the external auditory canal of the user. The wear detection sensor 254 may refer to, for example, a proximity sensor, but is not limited thereto. The wear detection sensor 254 may include an ultrasonic sensor, an infrared sensor, a touch sensor, or a combination thereof.

The second circuit board 255 may be disposed to be spaced apart from the first circuit board 252 and adjacent to the second housing 220. For example, the second circuit board 255 may be disposed on the other side of the battery 251 facing the side of the battery 251 on which the first circuit board 252 is disposed. According to an embodiment, the second circuit board 255 may be electrically connected to the external microphone 242. For example, the external microphone 242 may be disposed in one region of the second circuit board 255 to correspond to the position of the microphone hole 221 of the second housing 220. For example, the first and second circuit boards 252 and 255 may be at least one of a Printed Circuit Board (PCB) and a Flexible Printed Circuit Board (FPCB).

The connection portion 256 may electrically connect the first circuit board 252 and the second circuit board 255. According to an embodiment, the connection portion 256 may surround a portion of a sidewall of the battery 251 and extend from the first circuit board 252 to the second circuit board 255. The connection part 256 may be at least one of a Flexible Printed Circuit Board (FPCB) and a metal line, for example, formed of a polyimide material.

Spout 300 may connect interior space 201 of housing 200 to the exterior of wearable device 100. According to an embodiment, the mouthpiece 300 may be coupled to the housing 200 by being inserted into the through-hole 213. For example, spout 300 may be coupled to housing 200 such that a portion of spout 300 is located inside housing 200 and another portion of spout 300 is located outside wearable device 100. Another portion of mouthpiece 300 may be inserted into the external auditory canal of a user when wearable device 100 is worn on the user. According to an embodiment, spout 300 may be rotatably coupled to housing 200. For example, the nozzle 300 may be coupled to the housing 200 to be rotatable along the circumference of the through-hole 213. According to an embodiment, at least a portion of the cross section of spout 300 may have a shape corresponding to the cross section of through-hole 213. For example, the cross section of the through hole 213 may be circular, and the cross section of a portion of the nozzle 300 contacting the through hole 213 may be circular. Since the cross section of the nozzle 300 and the cross section of the through-hole 213 have shapes corresponding to each other, the nozzle 300 may have an axis coaxial with the through-hole 213 and rotate based on the through-hole 213.

According to an embodiment, spout 300 may include a tube 320 and a fastening portion 330. The audio path 310 formed by the tube 320 may transmit sound or signal output from the speaker 230 to the exterior of the wearable device 100. For example, the audio path 310 may extend from the interior space 201 toward the exterior of the wearable device 100. Audio output from speaker 230 may pass through audio path 310 of mouthpiece 300 in interior space 201 and may be transmitted to the exterior of wearable device 100.

According to an embodiment, spout 300 may be formed from multiple components. For example, spout 300 may be formed from two components that are bonded to one another. Two parts coupled to each other may form the tube 320 and the fastening part 330, respectively.

The tube 320 may be an acoustic transmission conduit that transmits sound or signal output from the speaker 230 to the outside or transmits sound or signal introduced from the outside to the microphone 240. At least a portion of the tube 320 may be exposed to the outside of the first housing 210.

The fastening portion 330 may be configured to couple the earplug 400 with the boss 300. According to an embodiment, the fastening portion 330 may be a protruding portion to which the earplug 400 is fastened, and may have a shape corresponding to a fastening groove (not shown) formed inside the earplug 400. According to an embodiment, the fastening part 330 may be coupled to one end of the tube 320 exposed to the outside of the first housing 210.

According to an embodiment, the thickness of the fastening part 330 may be 0.5mm or less. For example, when the mouthpiece 300 is formed by insert injection molding (insert injection), the thickness of the fastening portion 330 may be 0.05mm to 1mm. As the thickness of the fastening portion 330 is reduced, the size of the wearable device 100 may be reduced.

According to an embodiment, the fastening part 330 and the first housing 210 may be disposed to be spaced apart from each other. The separation distance r, which is the distance between the fastening portion 330 and the first housing 210, may affect the performance of the microphone 240. For example, as separation distance r decreases, performance of microphone 240 may increase. When the first housing 210 and the mouthpiece 300 are integrally manufactured, the separation distance r may be unnecessarily increased. For example, when the first housing 210 including the nozzle 300 is integrally formed, the separation distance r may be increased up to a minimum thickness capable of forming a mold. As the separation distance r increases, the length of the audio path 310 extending from the microphone 240 along the tube 320 may increase, so that the performance of the microphone 240 may deteriorate and the wearing comfort may decrease. According to an embodiment, the first housing 210 and the mouthpiece 300 of the wearable device 100 may be manufactured separately to prevent and/or reduce an unnecessary increase in the separation distance r. For example, the first housing 210 and the mouthpiece 300 may be manufactured separately. When the mouthpiece 300 is manufactured by inserting the tube 320 inside the first housing 210, the separation distance r may be set to ensure the performance of the microphone 240. Because the increase of the separation distance r is prevented/reduced, the wearable device 100 can ensure excellent performance of the microphone 240.

Earplug 400 may be coupled to a portion of spout 300 that is exposed to the exterior of housing 200. When the user wears the wearable apparatus 100, the ear plug 400 may be in close contact with the inner wall of the external auditory canal so that the audio output from the speaker 230 is smoothly transmitted to the user. In an embodiment, the earplug 400 may be formed of a silicon material. For example, at least one region of the earplug 400 may deform according to the shape of a user's ear when the wearable device 100 is worn on the user. For example, the earplug 400 may be formed of a combination of at least one of silicon, foam, and plastic.

According to the above-described embodiments, the wearable apparatus 100 may improve wearing comfort of a user by including the mouthpiece 300 rotatably coupled to the first housing 210 to be properly worn on the user's ear. For example, when mouthpiece 300 is coupled to housing 200 so as to be immovable, the user may not be able to adjust mouthpiece 300 to fit his or her ear because the ear shape of each user is different. According to an embodiment, when spout 300 is rotatably coupled to housing 200, wearable device 100 may improve the wearing comfort of the user by adjusting spout 300.

Fig. 2a is a cross-sectional view showing an example taken along a line A-A' of fig. 1b in a state where the first housing and the mouthpiece of the wearable device are fastened, and fig. 2b is a top view showing a state where the first housing and the mouthpiece of the wearable device are fastened.

Referring to fig. 2a and 2b, according to an embodiment, a first housing 210 forming an appearance of a wearable device 100 (e.g., the wearable device 100 of fig. 1 a) may be rotatably coupled to a mouthpiece 300. For example, the mouthpiece 300 may be inserted into the through-hole 213 and coupled to the first housing 210 such that the portion 300A of the mouthpiece 300 is located in the internal space 201.

According to an embodiment, the portion 300A of the nozzle 300 provided in the first housing 210 may have a shape of the flange 340. The flange 340 may be provided on the seating part 260 and supported by the seating part 260. For example, the flange 340 may be formed to extend from an end of the nozzle 300 in a radial direction of the through-hole 213. When the wearable device 100 is assembled, the mouthpiece 300 may be assembled to protrude from the inner space 201 to the outside of the first housing 210 through the penetration hole 213 of the first housing 210. When the mouthpiece 300 is assembled to protrude from the inner space 201 to the outside of the first housing 210, the flange 340 may determine the external protruding length of the mouthpiece 300 and prevent/restrain the mouthpiece 300 from being separated from the outside of the first housing 210.

According to an embodiment, the size of the flange 340 may be larger than the size of the through-hole 213 such that the nozzle 300 is not separated from the first housing 210. For example, the outer diameter of the flange 340 may be equal to or greater than the inner diameter of the through-hole 213. The outer diameter of the tube 320 may be smaller than the inner diameter of the through-hole 213 in consideration of errors such as manufacturing tolerances. The outer diameter of the flange 340 may be greater than the inner diameter of the through-hole 213. Since the outer diameter of the flange 340 is manufactured to be greater than the inner diameter of the through-hole 213, the flange 340 may be seated on the seating surface of the seating part 260. The nozzle 300 inserted into the through-hole 213 may be rotated along the circumference of the through-hole 213. For example, the nozzle 300 may be rotated clockwise or counterclockwise along the circumference of the through-hole 213 with respect to the first housing 210. The cross section of the through-hole 213 may be formed in a circular shape, and the cross section of the nozzle 300 may be manufactured in a circular shape to move along the through-hole 213.

According to an embodiment, the first housing 210 may include a seating portion 260 and a guide portion 270. The seating part 260 may support the flange 340 of the nozzle 300 provided in the first housing 210. According to an embodiment, the seating part 260 may be a portion of the first housing 210 formed along the circumference of the through-hole 213. For example, the seating part 260 may have a seating surface extending from a circumference of the through hole 213 in a radial direction of the through hole 213.

The guide 270 may be provided on the seating part 260 and guide the rotation of the nozzle 300. According to an embodiment, the guide 270 may include a guide protrusion 271 protruding from a seating surface of the seating part 260 contacting the flange 340 of the nozzle 300.

According to an embodiment, spout 300 may include guide slot 350. The guide groove 350 may receive the guide protrusion 271 and guide the rotation of the nozzle 300. In an embodiment, the guide groove 350 may be formed in the flange 340 of the nozzle 300 located in the first housing 210. For example, the guide groove 350 may be an empty space formed in the flange 340 surrounded by the sidewall 360. Since the guide groove 350 is formed in the flange 340, the guide groove 350 may rotate together with the nozzle 300. The position of the guide projection 271 in the guide groove 350 may be changed when the guide groove 350 rotates together with the mouthpiece 300. According to an embodiment, the guide groove 350 may be formed coaxially with the through-hole 213 such that the nozzle 300 rotates with respect to the axis of the through-hole 213. For example, the rotation center of the guide groove 350 may be the rotation center of the nozzle 300. The rotation axis of the nozzle 300 may pass through the center of a circle as a cross section of the through hole 213. Since the rotation axis of the nozzle 300 passes through the center of a circle as the cross section of the through-hole 213, and the cross sections of the nozzle 300 and the through-hole 213 are circular, the nozzle 300 inserted into the through-hole 213 can be rotated.

According to an embodiment, the guide groove 350 may extend along a portion of the circumference of the through hole 213. For example, the guide groove 350 may be in the form of an arc extending between one end portion 350a and the other end portion 350 b. The guide slot 350 may extend a distance that requires fine adjustment of the nozzle 300. According to an embodiment, both end portions 350a and 350b of the guide groove 350 may limit the rotation angle of the nozzle 300. For example, when the nozzle 300 rotates clockwise, the guide groove 350 may change the position of the guide projection 271 in a direction toward one end 350a of the guide groove 350. When the guide projection 271 is in contact with the one end portion 350a of the guide groove 350, the one end portion 350a of the guide groove 350 may serve as a stopper for preventing/reducing the rotation of the spout 300 in the clockwise direction. For another example, when the nozzle 300 is rotated counterclockwise, the guide groove 350 may change the position of the guide projection 271 in a direction toward the other end portion 350b of the guide groove 350. When the guide protrusion 271 is in contact with the other end portion 350b, the other end portion 350b of the guide groove 350 may serve as a stopper for preventing and/or reducing the rotation of the rotary nozzle 300.

According to the above-described embodiments, the wearable apparatus 100 may include the nozzle 300 rotatably coupled to the first housing 210 to be properly worn on the user's ear, thereby improving the wearing comfort of the user. The wearable device 100 can prevent/restrain the mouthpiece 300 from rapidly rotating beyond a specified range by providing the guide groove 350 for limiting the radius of rotation of the mouthpiece 300.

Fig. 3 is a diagram illustrating an example of a nozzle including a positioning protrusion according to an embodiment. The first housing 210 and the nozzle 300 of fig. 3 may be the first housing 210 and the nozzle 300 in which the structures of the first housing 210 and the nozzle 300 of fig. 1a, 1b, 2a, and/or 2b are changed, and a description thereof may not be repeated here.

Referring to fig. 3, according to an embodiment, the guide groove 350 may include a positioning protrusion 370.

The positioning tab 370 may interfere with the rotation of the mouthpiece 300, thereby providing a click feel to the user rotating the mouthpiece 300.
