[0085] According to one embodiment, the wearable electronic device (300) may include a housing (310), a grill (330), and a microphone (340). The description of the above-described components (e.g., the housing (310), the grill (330), the microphone (340)) may be substantially identical to the description of the components (e.g., the housing (310), the grill (330), the microphone (340)) described with reference to FIGS. 1 to 5.

[0086] According to one embodiment, the housing (310) may include an outer surface (310c). The outer surface (310c) may form a surface of the housing (310).

A portion of the air flowing along the outer surface (310c) of the housing (310) may be introduced into the chamber (314) through the apertures (331) of the grill (330).

[0088] In one embodiment, the housing (310) may include a chamber (314). The chamber (314) may form a space (3141) in the housing (310). For example, the chamber (314) may be formed by being recessed into an outer surface (310c) of the housing (310). The chamber (314) may be a part of the housing (310). The space (3141) may face the opening (313). The space (3141) may face the grill (330). In one embodiment, the chamber (314) may be formed by the housing (310) and the grill (330). For example, the chamber (314) may include the opening (313) and the space (3141). The grill (330) may be disposed in the space (3141) formed by the chamber (314). Chamber (314) may be referred to as a "groove". Chamber (314) may be referred to as a "recess". Chamber (314) may be referred to as a "home".

[0089] According to one embodiment, the chamber (314) may include a space (3141). The space (3141) may be connected to an opening (313). The space (3141) may be in communication with the outside of the housing (310). A portion of the air flowing along the outer surface (310c) of the housing (310) may be introduced into the space (3141). The air introduced into the space (3141) may be discharged to the outside of the housing (310) through the opening (313).

[0090] In one embodiment, the chamber (314) may include a first surface (3142). The first surface (3142) may face the opening (313). The first surface (3142) may be spaced apart from the grill (330). A space (3141) may be formed between the first surface (3142) and the grill (330). The first surface (3142) may be formed to be convex toward the opening (313). The first surface (3142) may have a curved shape. The first surface (3142) may be referred to as a “guide surface.”

[0091] According to one embodiment, the chamber (314) may include a second surface (3143). The second surface (3143) may extend from the first surface (3142) to an opening (313) of the housing (310).

[0092] In one embodiment, the chamber (314) may include a third surface (3144). The third surface (3144) may extend from the first surface (3142) to an opening (313) of the housing (310).

[0093] In one embodiment, each of the second surface (3143) and the third surface (3144) may be a portion of a peripheral surface (3149) of the chamber (314). For example, the chamber (314) may have a cylindrical peripheral surface (3149), and each of the second surface (3143) and the third surface (3144) may form an arch-shaped surface that is a portion of the peripheral surface (3149) of the chamber (314). For example, the second surface (3143) and the third surface (3144) may be different portions of the peripheral surface (3149) of the chamber (314). For example, the second surface (3143) and the third surface (3144) may be defined as a pair of portions that face each other on the peripheral surface (3149) of the chamber (314). The space (3141) of the chamber (314) can be formed between the second surface (3143) and the third surface (3144).

[0094] According to one embodiment, the first surface (3142) may include a first portion (3142a). The first portion (3142a) may extend in a curved shape toward the opening (313). The first surface (3142) may include a second portion (3142b). The second portion (3142b) may extend in a curved shape toward the opening (313).

The bend portion (3142c) may be formed at a location where the first portion (3142a) and the second portion (3142b) are connected. The first portion (3142a), the second portion (3142b), and the bend portion (3142c) may be integral. The inflection portion (3142c) may form a vertex of the first surface (3142) formed convexly. The first portion (3142a) may extend in a first direction (e.g., +X direction) and may be bent toward the opening (313) along the first direction. The second portion (3142b) may extend in a second direction (e.g., -X direction) opposite to the first direction and may be bent toward the opening (313) along the second direction. The first surface (3142) may be formed convexly in a third direction (e.g., -Z direction) intersecting the first and second directions (e.g., +X and -X directions). The third direction may be a direction facing the outside of the housing (310).

[0095] According to one embodiment, air flows (F1, F2) formed outside the housing (310) can flow along the outer surface (310c) of the housing (310) and can be introduced into the space (3141) inside the chamber (314). The air introduced into the space (3141) inside the chamber (314) can form a laminar flow along the first surface (3142). For example, the first flow (F1) can flow along the first portion (3142a), and the second flow (F2) can flow along the second portion (3142b). The first flow (F1) flowing along the first portion (3142a) and the second flow (F2) flowing along the second portion (3142b) can form a turbulent flow at the inflection portion (3142c). The flow (F1, F2) introduced into the internal space (3141) of the chamber (314) can flow along the first surface (3142) due to the Coanda effect.

[0096] According to one embodiment, air introduced into the chamber (314) can form airflows (A1, A2) within the space (3141). A portion of the air introduced into the chamber (314) can flow along the first portion (3142a) to form the first airflow (A1), and the remainder can flow along the second portion (3142b) to form the second airflow (A2). The first airflow (A1) can flow toward the opening (313) at a first inclination angle (θ1), and the second airflow (A2) can flow toward the opening (313) at a second inclination angle (θ2). According to various embodiments of the present disclosure, a wearable electronic device (300) can reduce the phenomenon in which noise generated by airflow is transmitted to a microphone (340) through a channel (315) by forming an airflow toward the outside of the housing (310) along a first surface (3142) that is convexly formed toward the opening (313). The first portion (3142a) may be referred to as a “first guide portion.” The second portion (3142b) may be referred to as a “second guide portion.”

[0097] According to one embodiment, the channel (315) may be formed at a position spaced apart from the first portion (3142a). The channel (315) may be formed at a position spaced apart from the inflection portion (3142c). The channel (315) may be formed by being opened in the second portion (3142b). The microphone (340) may be arranged so that the microphone hole (341) is in communication with the channel (315). A portion of the sound introduced into the space (3141) may be picked up by the microphone (340) through the channel (315). The air flow (F1, F2) introduced into the space (3141) may not be introduced into the channel (315) at least partially due to the shape of the chamber (314). For example, air flow (F1, F2) introduced into the space (3141) may flow toward the opening (313) due to the shape of the first surface (3142) and may not be introduced into the channel (315) at least in part.

[0098] In one embodiment, the first surface (3142) may include a third portion (3142d). The third portion (3142d) may be formed between the channel (315) and the third surface (3144). The third portion (3142d) may extend from the channel (315) toward the third surface (3144).

[0099] According to one embodiment, the first portion (3142a) and the second portion (3142b) may be distinguished based on the center line (CX1) illustrated in FIG. 8. For example, the first portion (3142a) and the second portion (3142b) may be defined as portions of the first surface (3142) located in different directions based on the center line (CX1) passing through the center (CP). For example, the first portion (3142a) may be a portion of the first surface (3142) located in the first direction (P1) based on the center line (CX1). For example, the second portion (3142b) may be a portion of the first surface (3142) located in the second direction (P2) based on the center line (CX1). According to one embodiment, the first portion (3142a) and the second portion (3142b) may be distinguished based on the flow direction of air. For example, referring to FIG. 7, the first portion (3142a) may be a portion of the first surface (3142) along which the first flow (F1) flows in a first direction (e.g., +X direction). For example, referring to FIG. 7, the second portion (3142b) may be a portion of the first surface (3142) along which the second flow (F2) flows in a second direction (e.g., -X direction).

[0100] In one embodiment, the housing (310) may include a channel (315). The channel (315) may be formed by opening in a first surface (3142) of the chamber (314). For example, the channel (315) may be formed by opening in a portion of the housing (310). The chamber (314) may be a portion of the housing (310) that is recessed into a surface of the housing (310), and the channel (315) may be formed in the recessed portion of the housing (310). The housing (310) may include a chamber (314) formed in a surface of the housing (310) and a channel (315) that is opened from the chamber (314) toward the microphone (340). The channel (315) may be open in a fourth direction (e.g., a +Z direction). The channel (315) may extend from the first surface (3142) of the chamber (314) in a direction (e.g., +Z direction) toward the inside of the housing (310). The channel (315) may be formed in the second portion (3142b) of the first surface (3142). The channel (315) may be formed at a position spaced apart from the inflection portion (3142c) in the first direction (+X direction). The channel (315) may connect the space (3141) inside the chamber (314) and the microphone hole (341) of the microphone (340). Sound from outside the housing (310) may be received by the microphone hole (341) through the space (3141) and the channel (315). The chamber (314) may be located between the opening (313) and the microphone (340). A channel (315) may connect a chamber (314) and a microphone (340). The channel (315) may be referred to as a “hole.” The channel (315) may be referred to as a “passage.”

The length (a) of the minor axis may be smaller than the length (b) of the major axis. The eccentricity (e) of the ellipse defined by the length (a) of the minor axis and the length (b) of the major axis (e) (e.g., e = (1-a) 2 / b 2 ) 1 / 2 ) can have a value in the range of about 0.65 to about 0.9.

[0102] According to one embodiment, the first surface (3142) may be a curved surface. For example, the first surface (3142) may be a portion of a circumferential surface of a three-dimensional object (C). For example, the three-dimensional object (C) may include an elliptical surface (CS) and a circumferential surface (RS). The circumferential surface (RS) may be a circumferential surface of an elliptical cylinder. The first surface (3142) may be a portion of the circumferential surface (RS). However, the definition of the first surface (3142) is not limited to that described above, and may be defined as a curved surface having a predetermined curvature.

[0103] In one embodiment, the center line (CX1) may pass through the elliptical center (CP) of the elliptical surface (CS) of the solid object (C). The chamber center (CX) may be spaced apart from the elliptical center (CP) of the solid object (C). The chamber center (CX) may be positioned offset from the center of the solid object (C).

[0104] According to one embodiment, the chamber (314) may have a chamber center (CX). The chamber (314) may have a cylindrical shape, and the chamber center (CX) may be the center of the cylindrical chamber (314). The peripheral surface (3149) of the chamber (314) may be a surface of a body of rotation about the chamber center (CX). A first distance between the second surface (3143) and the chamber center (CX) may be substantially equal to a second distance between the third surface (3144) and the chamber center (CX). A distance from the chamber center (CX) to the first outer surface (310a) and a distance from the chamber center (CX) to the second outer surface (310b) may be substantially equal.

The inflection portion (3142c) may be spaced apart from the chamber center (CX). The center line (CX1) may be spaced apart from the chamber center (CX). The chamber center (CX) may pass through the second portion (3142b). The center line (CX1) may pass through the inflection portion (3142c). The first surface (3142) may be formed to be convex toward the opening (313), and a vertex of the first surface (3142) (e.g., the inflection portion (3142c)) may be spaced apart from the chamber center (CX). The channel (315) may be positioned in a first direction (e.g., the +X direction) with respect to the chamber center (CX). The third portion (3142d) may be positioned in a first direction (+X direction) with respect to the chamber center (CX). The first portion (3142a) may be positioned in a second direction (e.g., -X direction) opposite to the first direction (+X direction) with respect to the chamber center (CX). The inflection portion (3142c) may be positioned in a second direction (-X direction) with respect to the chamber center (CX).

[0106] According to one embodiment, the first length (L1) from the inflection portion (3142c) to the second surface (3143) may be less than the second length (L2) from the inflection portion (3142c) to the third surface (3144).

[0107] Fig. 9a is a conceptual diagram illustrating the flow within a chamber (914) according to the first comparative example. Fig. 9b is a conceptual diagram illustrating the flow within a chamber (9140) according to the second comparative example.

[0108] According to a first comparative embodiment (e.g., FIG. 9a), a chamber (914) of a housing (910) includes a flat surface (9142). The flat surface (9142) is positioned between a space (9141) of the chamber (914) and a microphone (940). An opening (913) in the first comparative embodiment has a smaller width than an opening according to an embodiment of the present disclosure (e.g., an opening (313) of FIG. 7). Air introduced into the space (9141) through the opening (913) forms vortices (A3, A4) within the space (9141), and noise generated by the vortices (A3, A4) is transmitted to a microphone (940).

[0109] According to a second comparative example (e.g., FIG. 9b), the chamber (9140) of the housing (9100) includes a flat surface (91420). The flat surface (91420) is located between the space (91410) of the chamber (9140) and the microphone (9400).

The angle (e.g., θ3) at which the airflows (A5, A6) formed in the second comparative embodiment (e.g., FIG. 9b) are inclined toward the opening (9130) may be smaller than the angle (e.g., θ1, θ2) at which the airflows (e.g., A1, A2) formed inside the chamber (e.g., 314 of FIG. 7) according to one embodiment of the present disclosure are inclined toward the opening (e.g., 313 of FIG. 7). Air introduced into the chamber (e.g., 314 of FIG. 7) according to one embodiment of the present disclosure may collide with the first surface (e.g., 3142 of FIG. 7) of the chamber (e.g., 314 of FIG. 7) and diffract toward the opening (e.g., 313 of FIG. 7). According to one embodiment of the present disclosure, the angle at which air is diffracted (e.g., θ1, θ2) may be greater than the angle at which air is diffracted (e.g., θ3) according to the comparative embodiment. In the second comparative embodiment, the air introduced into the chamber (9140) has a longer residence time inside the chamber than the air introduced into the chamber (e.g., 314 of FIG. 7) according to one embodiment of the present disclosure. The air introduced into and remaining in the chamber (9140) may transmit noise to the microphone (9400).

[0110] FIG. 9C is a drawing illustrating a portion of a housing (410) of a wearable electronic device (300) according to one embodiment of the present disclosure. The components described with reference to FIG. 9C may be partially or entirely identical to the components described with reference to FIGS. 1 to 8.

[0111] According to one embodiment, the housing (410) may include a chamber (414). The chamber (414) may have a cylindrical peripheral surface (4149). A space (4141) may be formed inside the chamber (414). The chamber (414) may include a first surface (4142), a second surface (4143), and a third surface (4144). The first surface (4142) may be formed to be convex toward the opening (313). The first surface (4142) may include a first portion (4142a), a second portion (4142b), and a bend portion (4142c). The chamber (414) may include a chamber center (CX). The chamber center (CX) may pass through the bend portion (4142c). The first part (4142a) and the second part (4142b) may be formed in opposite directions based on the inflection part (4142c). The chamber center (CX) may distinguish the first part (4142a) and the second part (4142b). A channel (415) may be formed in the second part (4142b). The channel (415) may be communicated with the microphone hole (341) of the microphone (340). The first flow (F1) and the second flow (F2) may be introduced into the chamber (414) and form airflows (A7, A8) in the space (4141).

[0112] FIG. 10 is a conceptual diagram illustrating a computer simulation domain for noise measurement of a wearable electronic device (300) according to an embodiment of the present disclosure. The computer simulation domain (S) illustrated in FIG. 10 includes a generator (G) that generates airflow toward a person (H) and a wearable electronic device (300) mounted on the ear (E) of the person (H).

[0113] Fig. 11 is a graph comparing simulation data for the embodiments of Figs. 9b, 9c, and 7 in the domain of Fig. 10, respectively. It can be confirmed that the noise level (S3) according to the embodiment of Fig. 7 is lower than the noise level (S1) according to the embodiment of Fig. 9b. It can be confirmed that the noise level (S2) according to the embodiment of Fig. 9c is lower than the noise level (S1) according to the embodiment of Fig. 9b.

[0114] Figures 12a and 12b are diagrams illustrating airflows (F1, F2) around a wearable electronic device (300) inserted into a user's ear (E). Referring to Figures 12a and 12b, it can be confirmed that a direct airflow (F1) and an indirect airflow (F2) are formed toward the wearable electronic device (300).

[0115] Fig. 13a is a diagram showing the airflow inside a chamber (9140) according to the embodiment of Fig. 9b. Fig. 13b is a diagram showing the airflow inside a chamber (414) according to the embodiment of Fig. 9c. Fig. 13c is a diagram showing the airflow inside a chamber (314) according to the embodiment of Fig. 7. The components described with reference to Figs. 13a to 13c may be partially or entirely the same as the components described with reference to Figs. 1 to 12b.

[0116] Referring to FIG. 13c, the first flow (F1) and the second flow (F2) can form an airflow (F3) (e.g., laminar flow) along the first surface (3142). The first flow (F1) and the second flow (F2) can form a mixed airflow (F4) at the inflection portion (3142c) of the first surface (3142) and can be discharged to the outside of the wearable electronic device (300). The wearable electronic device (300) according to the embodiment of the present disclosure can form the inflection portion (3142c) at a location spaced apart from the center (CX) of the chamber (314), thereby spaced apart the formation location of the mixed airflow (F4) from the channel (315). By separating the formation location of the mixed air flow (F4) from the channel (315), the phenomenon of air flow (e.g., noise caused by wind) outside the wearable electronic device (300) flowing into the channel (315) can be reduced.

[0117] The wearable electronic device (300) according to an embodiment of the present disclosure can cause airflow introduced into the chamber (314) to flow toward the opening (313) rather than the channel (315) by forming the first surface (3142) of the chamber (314) convexly toward the opening (313). The wearable electronic device (300) can reduce airflow introduced into the channel (315) by spacing the inflection portion (3142c) of the first surface (3142) away from the chamber center (CX) in the opposite direction to the channel (315). The wearable electronic device (300) can improve the distance that the indirect airflow (F2) flows along the first surface (3142) by the Coanda effect by spacing the inflection portion (3142c) of the first surface (3142) away from the chamber center (CX). Compared to the direct airflow (F1), the indirect airflow (F2) may have a lower velocity, and due to the position of the inflection point (3142c), the indirect airflow (F2) may be guided to the opening (313) by the Coanda effect of the first surface (3142).

[0118] A wearable electronic device includes a housing with an opening. A microphone is positioned inside the housing to pick up external sounds through the opening. Air flowing outside the housing can be picked up by the microphone and perceived as noise.

[0119] A problem to be solved in the present disclosure may be to reduce noise picked up by a microphone.

[0120] A problem to be solved in the present disclosure may be to simplify the chamber structure of the housing.

[0121] The problem to be solved in this disclosure is not limited to the problem mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.
