The first inner surface (2112) may face in the +Z direction or the center of the wearable electronic device (201) (e.g., the center (O') in FIG. 5).

[0114] According to one embodiment, the first inner surface (2112) may be partially recessed in a direction away from the center of the wearable electronic device (201) (e.g., the center (O') in FIG. 5). The first inner surface (2112) may form a first recess (e.g., 2131 in FIG. 6) in which part is recessed. The first recess (e.g., 2131a in FIG. 6) may form part of each of at least two holes (213a, 213b). For example, the first recess (e.g., 2131a in FIG. 6) may form the first hole (213a) together with the second recess (e.g., 2132a in FIG. 6). Although not shown, the second hole (213b) may be formed with two recesses (e.g., the first recess (2131a) and the second recess (2132a) of FIG. 6) in the same way as the first hole (213a).

[0115] According to one embodiment, the ring-shaped housing (210) may include a second ring housing part (212). The second ring housing part (212) may include a second inner surface (2122) facing the direction in which the first inner surface (2112) or the outer surface (2111) faces. The second ring housing part (212) may include an inner surface (2121) facing opposite to the first inner surface (2112) or facing the center of the wearable electronic device (201) (e.g., the center (O') in FIG. 5). The inner surface (2121) may come into contact with the user's body.

[0116] According to one embodiment, a portion of the second inner surface (2122) may be recessed toward the center of the wearable electronic device (201) (e.g., center (O') in FIG. 5). The second inner surface (2122) may form a second recess (e.g., 2132a in FIG. 6) that is partially recessed. The second recess (e.g., 2132a in FIG. 6) may form a portion of each of at least two holes (213a, 213b). For example, the second recess (e.g., 2132a in FIG. 6) may form the first hole (213a) together with the first recess (e.g., 2131a in FIG. 6). Although not shown, the second hole (213b) may be formed with two recesses (e.g., the first recess (2131a) and the second recess (2132a) of FIG. 6) in the same way as the first hole (213a).

[0117] According to one embodiment, at least two holes (213a, 213b) may be formed in a ring-shaped housing (210). The at least two holes (213a, 213b) may include a first hole (213a) facing a first direction (+X direction). For example, the first hole (213a) may be formed between a first ring housing part (211) and a second ring housing part (212). The at least two holes (213a, 213b) may include a second hole (213b) facing a direction opposite to the first direction (+X direction) (-X direction). For example, the second hole (213b) may be formed between a first ring housing part (211) and a second ring housing part (212).

[0118] According to one embodiment, the first hole (213a) and the second hole (213b) can output sound from the speaker (231) to the outside of the ring-shaped housing (210). Alternatively, if one of the first hole (213a) or the second hole (213b) is closed, sound having an audible frequency can be output or transmitted to the outside of the wearable electronic device (201) through the other. For example, when a user places the wearable electronic device (201) on the floor, one of the first hole (213a) or the second hole (213b) (e.g., the second hole (213b)) is closed, and sound having a frequency of 3 to 4 kHz can be transmitted to the user through the open hole (e.g., the first hole (213a)).

[0119] According to one embodiment, a first space (214) may be formed inside a ring-shaped housing (210) between a speaker (231) (or a diaphragm of the speaker) and a first ring housing part or between a second ring housing part. The first space (214) may connect at least two holes (213a, 213b) or connect the first hole (213a) and the second hole (213b). The first space (214) may output sound output from the speaker (231) to the outside through the first hole (213a) and / or the second hole (213b). The first space (214) may form part of an acoustic conduit for communicating sound to the outside of a wearable electronic device (201). For example, sound output from the speaker (231) can be output or transmitted to the outside of the ring-shaped housing (210) through the first space (214) and / or the first hole (213a) and / or the second hole (213b) so that the user can perceive the sound.

[0120] In the present disclosure, the wearable electronic device (201) may include an acoustic space (213 and 214) comprising a first space (214) and at least two holes (213). Alternatively, the acoustic space (213 and 214) may be formed through the first space and at least two holes.

[0121] In the present disclosure, the acoustic space (213 and 214) may be configured such that when at least two holes (213) are both open, sound output from the speaker (231) provides a harmonic sound wave of a first frequency (e.g., f2 in FIG. 12b) in the acoustic space (213 and 214). For example, all holes may be open so that resonance (or standing wave) occurs in the open tube (or open tube) and sound of the first frequency (e.g., f2 in FIG. 12b) may be output outside the wearable electronic device (201).

[0122] In the present disclosure, the acoustic space (213 and 214) may be configured such that when only some of at least two holes (213) are open, sound output from the speaker (231) provides harmonics of a second frequency (e.g., f1 in FIG. 12a) in the acoustic space (213 and 214). For example, when only some of the holes are open, resonance (or standing waves) occurs in the open tube (or open tube) so that sound of the second frequency (e.g., f1 in FIG. 12a) may be output outside the wearable electronic device (201).

[0123] According to one embodiment, the wearable electronic device (201) may include a speaker assembly (230).

[0124] According to one embodiment, the speaker assembly (230) may include a speaker (231). The speaker (231) may be disposed on a second ring housing part (212) or a second inner surface (2122) inside the ring-shaped housing (210). The speaker (231) may be disposed so as to be spaced apart from the first ring housing part (211) or the first inner surface (2112) by a first distance (T1). The speaker (231) may be spaced apart from the first ring housing part (211) by a first distance (T1) to form a first space (214) between the first ring housing part (211) and the speaker (231).

[0125] According to one embodiment, the speaker assembly (230) may include a bracket (232). The bracket (232) may be placed in a second ring housing part (212) to surround the speaker (231) within the internal space of the ring-shaped housing (210). The bracket (232) may surround the speaker (231) and may be partially open toward the first ring housing part (211) corresponding to the area where the speaker (231) is placed. The bracket (232) may secure the speaker (231) so that the speaker (231) maintains a distance from the first ring housing part (211). The bracket (232) may surround the speaker (231) and may partially contact a portion of the second inner surface (2122) of the second ring housing part (212) and a portion of the first inner surface (2112) of the first ring housing part (211).

[0126] According to one embodiment, the bracket (232) may include contact portions (2322a, 2322b) that contact a first inner surface (2112) and a second inner surface (2122) in the internal space of a ring-shaped housing (210). The contact portions (2322a, 2322b) may include a first contact portion (2322b) that contacts a first ring housing part (211) or a first inner surface (2112). The contact portions (2322a, 2322b) may include a second contact portion (2322a) that contacts a second ring housing part (212) or a second inner surface (2122).

[0127] According to one embodiment, the bracket (232) may include at least two openings (2321). The at least two openings (2321) may be formed at positions corresponding to the first hole (213a) and the second hole (213b). The at least two openings (2321) may be connected to the first space (214). For example, the first space (214) may be connected to the at least two openings (2321) and may be connected to the first hole (213a) and the second hole (213b) through the at least two openings (2321). The first space (214), the at least two openings (2321), the first hole (213a), and the second hole (213b) may form an acoustic conduit (or acoustic space).

[0128] The speaker assembly (230) described with reference to FIGS. 7a and 7b is described as having a structure that is positioned in the second ring housing part (212) and spaced apart from the first ring housing part (211) for convenience of explanation, but is not limited thereto and may be positioned in the first ring housing part (211) and spaced apart from the second ring housing part (212).

[0165] The description of the ring-shaped housing (510), the first ring housing part (511), and the second ring housing part (512) described with reference to FIG. 10 may be adapted from the description of the ring-shaped housing (e.g., 210 in FIG. 7a), the first ring housing part (e.g., 211 in FIG. 7a), and the second ring housing part (e.g., 212 in FIG. 7a) described with reference to FIG. 7a through FIG. 9, to the extent that such adaptation does not conflict.

[0166] FIG. 11 is a drawing for illustrating an example of use of a wearable electronic device according to one embodiment of the present disclosure.

[0167] The usage example described with reference to FIG. 11 may be a usage example of the embodiments described with reference to FIG. 1 to 10. The configurations described with reference to FIG. 10 may be substantially identical to the configurations described with reference to FIG. 1 to 10. The effects of the usage examples of FIG. 10 may be identical to FIG. 12a and FIG. 12b. Configurations not described below may be substantially identical to the configurations described with reference to FIG. 1 to 10.

[0168] According to one embodiment, the wearable electronic device (601) may include a ring-shaped housing (610), a battery (e.g., 220 in FIG. 5), a speaker assembly (630), a printed circuit board (e.g., 240 in FIG. 5), electronic components (e.g., a sensor (260) in FIG. 5, or a light-emitting part (270)) and a blocking member (e.g., 270 in FIG. 5).

[0169] According to one embodiment, the ring-shaped housing (610) may include a first ring housing part (611) and a second ring housing part (612). The ring-shaped housing (610) may form a first space (614) between the first ring housing part (611) and the speaker assembly (630) in the internal space. The ring-shaped housing (610) of FIG. 11 may utilize the ring-shaped housing of FIG. 7a through FIG. 10 (e.g., 210 of FIG. 7a).

[0170] According to one embodiment, the speaker assembly (630) may include a speaker (631) that transmits sound or vibration and a bracket (632) that secures the same. The speaker assembly (630) of FIG. 11 may utilize the speaker assembly of FIG. 7a through FIG. 10 (e.g., 230 of FIG. 7a).

[0171] A wearable electronic device (601) according to one embodiment of the present disclosure may convey a notification to a user through sound or vibration. For example, the user may receive a notification sound (S) conveyed from the wearable electronic device (601). Alternatively, the user may receive a notification sound (S) by vibration when the haptic module of the wearable electronic device (601) vibrates, or may receive vibration through the first ring housing part (611) and / or the second ring housing part (612) when the user wears it.

[0172] According to one embodiment, a wearable electronic device (601) may come into contact with an external object (1000). The wearable electronic device (601) may have a side portion (6151a) of the outer surface (6111) and / or a side portion (6152a) of the inner surface (6121) come into contact with the external object (1000). For example, the wearable electronic device (601), separated from the user, may be placed on the external object (1000) so that one of the side portions (e.g., 215a, 215b in FIG. 3) of the ring-shaped housing (610) may come into contact with the external object (1000). The external object (1000) may be, for example, a floor surface or a desk, but is not limited thereto.

[0173] According to one embodiment, a wearable electronic device (601) in contact with an external object (1000) may have at least one of two holes (613a, 613b) closed by the external object (1000).

[0174] According to one embodiment, the wearable electronic device (601) can output a sound (S) to the outside of the ring-shaped housing (610) through the first space (614) and one of the at least two holes (613a, 613b) that is open, while one of the two holes (613b) is closed. The output sound (S) can propagate into the air in a direction away from the external object (1000) and be transmitted to the user's ear (E') as a sound (S') having an audible frequency. For example, according to one embodiment of the present disclosure, the wearable electronic device (601) allows the user to hear the notification sound (S) of the wearable electronic device (601) through the other open hole (613a) even if one hole (613b) is closed.

[0175] According to one embodiment, the wearable electronic device (601) may be configured to automatically operate the actuator (631) to output the notification sound (S) upon a user's request or when a condition according to a specified setting is met. For example, the wearable electronic device (601) may be configured to output the notification sound (S) when the user requests to check information about the location of the wearable electronic device (601) or when the remaining power of the battery of the wearable electronic device (601) is below a specified value. Since the size of the wearable electronic device (601) is relatively small compared to other portable electronic devices (e.g., smartphones), it may be configured to allow the user to quickly recognize the location of the wearable electronic device (601) if the user forgets the location of the wearable electronic device (601).

[0176] FIG. 12a is a drawing for explaining the effect of a wearable electronic device according to one embodiment of the present disclosure.

[0177] FIG. 12b is a drawing for explaining the effect of a wearable electronic device according to one embodiment of the present disclosure.

[0178] The effects of the embodiments described with reference to FIGS. 12a and 12b may be the same as the effects of the embodiments described with reference to FIGS. 1 to 11. The configurations of FIGS. 12a and 12b may be the same as the configurations of FIGS. 1 to 11.

[0179] Referring to FIG. 12a, the first embodiment (901a) can describe the magnitude of the pressure acting on the second frequency (f1) and the acoustic duct (or, for example, the first space (214) and at least two holes (213)) of FIG. 7a in a closed state (900a) of at least two holes (e.g., 201 of FIG. 7a) of a wearable electronic device (e.g., 213a of FIG. 7a). In the first embodiment (901a), the pressure (Pa) in one open hole (e.g., 613a of FIG. 11) may be greater than the pressure (Pa) in the other closed hole (e.g., 613b of FIG. 11). The second frequency (f1) may be about 3 kHz to about 4 kHz.

[0180] Referring to FIG. 12b, the second embodiment (901b) can describe a first frequency (f2) and sound pressure in a state (900b) where one of the two holes (e.g., 213a, 213b of FIG. 7a) of a wearable electronic device (e.g., 201 of FIG. 7a) is closed. In the second embodiment (901b), when both of the two holes (e.g., 13a, 213b of FIG. 7a) are open, the pressure (Pa) in both of the two holes (e.g., 213a, 213b of FIG. 7a) may be lower than the pressure (Pa) in the one closed hole (e.g., 613b of FIG. 11) in the first embodiment (901a). When both of the two holes (e.g., 213a and 213b of FIG. 7a) are open, the first frequency (f2) may be greater than the second frequency (f1). For example, the first frequency (f2) may be about 5 kHz.

[0181] Referring to FIGS. 12a and 12b, the frequency may differ depending on the pressure in at least two holes (e.g., 213a and 213b in FIG. 7a) depending on whether at least one of the at least two holes (e.g., 213a and 213b in FIG. 7a) is open or closed. For example, if a greater pressure is applied to one of the at least two holes (e.g., 613a in FIG. 7a) than to the other (e.g., 613b in FIG. 11), the frequency may be lower than when both are open.

[0182] The first embodiment (901a) and the second embodiment (901b) described with reference to FIGS. 12a and 12b may be substantially identical to the wearable electronic device of the present disclosure (e.g., 201 of FIG. 7a).

[0183] The sound of the first frequency (f2) described in the present disclosure may be a harmonic to the sound output from the speaker (231) when at least two holes (e.g., 213 in FIG. 7a) are both open. For example, sound may be output from the speaker (231) and at least two holes (e.g., 213 in FIG. 7a) may be both open to form a standing wave or resonance. For example, the harmonic of the first frequency (f2) may be a standing wave in an open tube.

[0184] The sound of the second frequency (f1) described in the present disclosure may be a harmonic to the sound output from the speaker (231) when some of at least two holes (e.g., 213 in FIG. 7a) are open or some are closed. For example, sound may be output from the speaker (231), and a standing wave or resonance may be formed through the open hole that is not closed among the at least two holes (e.g., 213 in FIG. 7a). For example, the harmonic of the second frequency (f1) may be a standing wave in a tube in which some parts are closed.

[0185] The wearable electronic device of the present disclosure (e.g., 201 in FIG. 7a) can provide notifications to the user.

[0186] The wearable electronic device of the present disclosure (e.g., 201 in FIG. 7a) may include a plurality of holes that output sound.

[0187] The wearable electronic device of the present disclosure (e.g., 201 in FIG. 7a) can provide notification information to the user through a sound of an audible frequency while separated from the user through a plurality of holes that output sound and with part of the holes closed.

[0188] The wearable electronic device of the present disclosure (e.g., 201 in FIG. 7a) can secure a speaker (e.g., 231 in FIG. 7a) through a bracket (e.g., 232 in FIG. 7a) and secure space between the speaker (e.g., 231 in FIG. 7a) and a ring-shaped housing (e.g., 230 in FIG. 7a).

[0189] The wearable electronic device of the present disclosure (e.g., 201 in FIG. 7a) can efficiently transmit sound through a space (e.g., 214 in FIG. 7a) between a speaker (e.g., 231 in FIG. 7a) and a ring-shaped housing (e.g., 210 in FIG. 7a).

[0190] The wearable electronic device of the present disclosure (e.g., 201 in FIG. 7a) can provide information to a user through sound and / or vibration by a speaker (e.g., 231 in FIG. 7a).

[0191] The wearable electronic device of the present disclosure (e.g., 201 in FIG. 7a) can provide location information when separated from the user through sound or vibration.
