According to an embodiment, the second housing 112 may be coupled to the first housing 111. For example, the second housing 112 may be manufactured separately from the first housing 111 and then coupled to the first housing 111. For example, the second housing 112 may be coupled to the first housing 111 by a snap-fit ​​method, but is not limited thereto.

[0019] According to an embodiment, the nozzle portion 113 may provide a channel through which audio from at least one speaker 130 may be emitted to the outside of the housing 110. The nozzle portion 113 may define (or form) a first audio path 113a. For example, the nozzle portion 113 may surround (or enclose) the first audio path 113a. The first audio path 113a may extend from at least one speaker 130 toward the outside of the electronic device 100 (or the outside of the housing 110). For example, the first audio path 113a may extend from a first surface 130a of at least one speaker 130 to the outside of the electronic device 100 (or the outside of the housing 110). According to an embodiment, when the electronic device 100 is worn by a user, the nozzle portion 113 may be accommodated in the user's ear canal e1. For example, when the electronic device 100 is worn by a user, the nozzle portion 113 may be inserted into the user's ear canal e1. Since the nozzle portion 113 is inserted into the user's ear canal e1 when the electronic device 100 is worn by the user, the electronic device 100 may be referred to as a core-type headphone.

[0020] According to an embodiment, the vent 114 can connect the exterior and interior of the housing 110. The vent 114 provides a channel through which sound from outside the housing 110 is transmitted to the user's ear canal e1 when the electronic device 100 is worn by the user. The vent 114 can be spaced apart from the first audio path 113a. The vent 114 can penetrate the housing 110. For example, the vent 114 can penetrate the area of ​​the housing 110 corresponding to the side surface 130c of at least one speaker 130. For example, the vent 114 can be formed (or positioned) in the area of ​​the housing 110 corresponding to the side surface 130c of at least one speaker 130.

[0021] According to an embodiment, a side surface 130c of at least one speaker 130 may be disposed between a first surface 130a and a second surface 130b of at least one speaker 130. The first surface 130a of at least one speaker 130 may face the nozzle portion 113. The first surface 130a of at least one speaker 130 may contact the first audio path 113a. The second surface 130b of at least one speaker 130 may be opposite to the first surface 130a of at least one speaker 130. The direction (e.g., +z direction) facing the second surface 130b of at least one speaker 130 may be opposite to the direction (e.g., -z direction) facing the first surface 130a of at least one speaker 130. The second surface 130b of at least one speaker 130 may face the first support 140. The side surface 130c of at least one speaker 130 may connect to the first surface 130a and the second surface 130b of at least one speaker 130. For example, the side surface 130c of at least one speaker 130 may connect to the periphery of the first surface 130a and the periphery of the second surface 130b of at least one speaker 130.

[0022] According to one embodiment, the microphone hole 115 can provide a channel through which sound from outside the housing 110 can be transmitted to the interior of the housing 110. Sound from outside the housing 110 can also be transmitted to the interior of the housing 110 through the microphone hole 115. For example, the location of the microphone hole 115 can correspond to the location of at least one microphone 170 within the housing 110. The microphone hole 115 can penetrate the housing 110. For example, the microphone hole 115 can penetrate the second housing 112.

[0023] According to an embodiment, when the electronic device 100 is worn by a user, the earbud head 120 can be inserted into (or accommodated) in the user's ear canal e1. For example, when the electronic device 100 is worn by a user, the earbud head 120 can contact the user's ear canal e1. The earbud head 120 can be detachably (or separably) attached to the housing 110. For example, the earbud head 120 can be detachably (or separably) attached to the nozzle portion 113 of the housing 110. For example, when attached to the housing 110, the earbud head 120 can surround or enclose at least a portion of the nozzle portion 113. According to an embodiment, when the electronic device 100 is worn by a user, the earbud head 120 can be deformable to correspond to the internal shape of the user's ear canal e1. For example, the earbud head 120 can be formed of an elastic material.

[0024] According to an embodiment, at least one speaker 130 can be configured to emit (or output) audio. At least one speaker 130 can emit (or output) audio through at least one of a first surface 130a and a second surface 130b. A first audio signal can be emitted through the first surface 130a of the at least one speaker 130, and a second audio signal, different from the first audio signal, can be emitted through the second surface 130b of the at least one speaker. For example, the second audio signal may have a lower frequency than the first audio signal. In the case where the second audio signal has a lower frequency than the first audio signal, the first audio signal can be emitted from a first diaphragm facing the first surface 130a (e.g., ...). Figure 2b The first vibrating plate 131) emits (or outputs) a second audio signal, which can be emitted (or output) from the second vibrating plate facing the second surface 130b (e.g., Figure 2b The second diaphragm 132 emits (or outputs) the signal. For example, the first diaphragm 131 may form the tweeter of at least one speaker 130, and the second diaphragm 132 may form the woofer of at least one speaker. For example, the second audio signal may be referred to as the rear sound. However, it is not limited thereto. For example, the second audio signal may have a different phase than the first audio signal. In the case where the second audio signal and the first audio signal have different phases, at least one speaker 130 may include only one diaphragm facing the first surface 130a. The first audio signal from the first surface 130a of at least one speaker 130 may be transmitted to the outside of the housing 110 along the first audio path 113a. The second audio signal from the second surface 130b of at least one speaker 130 may pass through the vent 114 and be transmitted to the outside of the housing 110.

[0025] According to an embodiment, a first bracket 140 may be disposed between at least one speaker 130 and electronic component 150. The first bracket 140 can separate a first space 111a and a second space 112a within the housing 110. For example, a portion of the first bracket 140 may be disposed between the first space 111a and the second space 112a. The first bracket 140 can separate the first space 111a in which at least one speaker 130 is disposed and the second space 112b in which the electronic component 150 is disposed, thereby reducing electrical interference between the at least one speaker 130 and the electronic component 150. For example, the first bracket 140 may be formed of a non-conductive material, but is not limited thereto.

[0026] According to one embodiment, the first support 140 may include a flange 141 and a guide 142. The flange 141 may be disposed on a second surface 130b of at least one speaker 130. For example, the flange 141 may cover the second surface 130b of at least one speaker 130. The guide 142 may guide second audio from the second surface 130b of at least one speaker 130 to the outside of the housing 110. The guide 142 may be connected to the flange 141. The guide 142 may contact the flange 141. For example, the guide 142 may be integrally formed with the flange 141. According to one embodiment, the guide 142 may be disposed (or extend) along at least a portion of a side surface 130c of at least one speaker 130. For example, the guide 142 may surround (or encircle) said at least a portion of the side surface 130c of at least one speaker 130. For example, the guide portion 142 may overlap with at least a portion of the side surface 130c of at least one speaker 130, but may not overlap with the first surface 130a and the second surface 130b of at least one speaker 130.

[0027] According to various embodiments, electronic component 150 can perform various functions, enabling electronic device 100 to provide various functions to the user. For example, electronic component 150 may include battery 151 and / or printed circuit board 152. Battery 151 may store power to be supplied to electronic component 150 and at least one speaker 130. According to various embodiments, battery 151 may be disposed on a first support 140. For example, battery 151 may be disposed on flange 141. Printed circuit board 152 may be disposed on a second support 160. For example, printed circuit board 152 may include a processor for controlling the operation of battery 151 and at least one speaker 130. For example, printed circuit board 152 may include communication circuitry for communicating with other electronic devices external to electronic device 100. However, the examples of electronic component 150 are not limited to the above, and electronic device 100 may further include other electronic components.

[0028] According to an embodiment, the second bracket 160 can be disposed between the battery 151 and the printed circuit board 152. Because the second bracket 160 is disposed between the battery 151 and the printed circuit board 152, electrical interference between the battery 151 and the printed circuit board 152 can be reduced. For example, the second bracket 160 can be formed of a non-conductive material, but is not limited thereto.

[0029] According to an embodiment, at least one microphone 170 can acquire electrical signals based on sound from outside the housing 110. For example, at least one microphone 170 can be used to acquire a user's voice. For example, at least one microphone 170 can be used to implement noise reduction functionality. According to an embodiment, at least one microphone 170 can be disposed within the housing 110. For example, at least one microphone 170 can be disposed within a second housing 112. When at least one microphone 170 is disposed within the second housing 112, at least one microphone 170 can face the microphone hole 115. For example, at least one microphone 170 can be disposed on a printed circuit board 152. However, it is not limited to this. For example, at least one microphone 170 can be disposed within a first housing 111.

[0030] For example, when the electronic device 100 is worn by the user, the earbud head 120 can be in close contact with the user's ear canal e1. When the electronic device 100 is worn by the user, the vent 114 and microphone hole 115 can be positioned outside the user's ear canal e1. When the electronic device 100 is worn by the user, the vent 114 and microphone hole 115 may not be inserted into the user's ear canal e1. Without the vent 114, sound from outside the ear canal e1 cannot be transmitted to the inside of the ear canal e1 when the earbud head 120 is in close contact with the user's ear canal e1, which may cause discomfort to the user. With the vent 114 formed, sound (or air) can move between the inside and outside of the ear canal e1 when the earbud head 120 is in close contact with the ear canal e1, thus reducing user discomfort. When at least one speaker 130 is in operation with the earbud head 120 in close contact with the user's ear canal e1, a first audio signal from the first surface 130a of the at least one speaker 130 can be transmitted to the eardrum along the user's ear canal e1 by being released to the outside of the housing 110. Simultaneously with the first audio signal, a second audio signal from the second surface 130b of the at least one speaker 130 can be emitted to the outside of the housing 110 through an exhaust port 114 located outside the ear canal e1. The second audio signal emitted through the exhaust port 114 can be received by a microphone 170 via a microphone hole 115 located outside the ear canal e1. When the second audio signal is received by the microphone 170, a whistling sound based on audio feedback may occur, where the second audio signal is again output through the at least one speaker 130. The structure of the electronic device 100 for reducing whistling sound will be described below.

[0032] Reference Figure 2a , Figure 2b and Figure 2c According to an embodiment, the flange portion 141 may be provided in the first housing 111 and the second housing 112 of the housing 110. According to an embodiment, the vent 114 may have a shape extending along the axis a1 of the housing 110. For example, the major axis 114a of the vent 114 may be substantially parallel to the axis a1 of the housing 110, but is not limited thereto. For example, the angle between the major axis 114a of the vent 114 and the axis a1 of the housing 110 may be an acute angle. The axis a1 of the housing 110 may be substantially parallel to the first audio path 113a. The axis a1 of the housing 110 may be substantially parallel to the extending direction of the nozzle portion 113. Meanwhile, in Figure 2a In the diagram, the vent 114 is shown in the form of having a major axis 114a, but the shape of the vent 114 is not limited to this. For example, the vent 114 may have a circular shape and / or a polygonal shape without a major axis 114a.

[0033] According to one embodiment, at least one speaker 130 may include a first diaphragm 131, a second diaphragm 132, and / or an enclosure 133. According to one embodiment, the first diaphragm 131 may face a first surface 130a. The first diaphragm 131 may output a first audio signal toward the first surface 130a. The first audio signal emitted from the first diaphragm 131 may pass through a nozzle portion 113 along a first audio path 113a after passing through the first surface 130a. The first audio signal may be transmitted to the outside of the housing 110 after passing through the nozzle portion 113.

[0034] According to an embodiment, the second vibrating plate 132 may face the second surface 130b. The second vibrating plate 132 may output a second audio frequency. For example, the second vibrating plate 132 may operate (or vibrate) independently of the first vibrating plate 131. The second vibrating plate 132 may be disposed on the first vibrating plate 131. The second audio frequency emitted from the second vibrating plate 132 may pass through the second surface 130b. The second audio frequency passing through the second surface 130b may be transmitted to the first space 111a of the housing 110.

[0035] According to an embodiment, the surrounding element 133 may define (or form) the outer surface of at least one speaker 130. For example, the surrounding element 133 may define (or form) a first surface 130a, a second surface 130b, and / or a side surface 130c as the outer surface of at least one speaker 130. The surrounding element 133 may accommodate a first diaphragm 131 and a second diaphragm 132. The surrounding element 133 may surround (or enclose) the first diaphragm 131 and the second diaphragm 132. According to an embodiment, the surrounding element 133 may include at least one first hole and at least one second hole. The at least one first hole may penetrate the first surface 130a. The at least one first hole may be formed on the first surface 130a. The at least one first hole may provide a channel through which first audio from the first diaphragm 131 is transmitted to a first audio path 113a. The at least one second hole may penetrate the second surface 130b. The at least one second hole may be formed on the second surface 130b. The at least one second hole may provide a channel through which second audio from the second diaphragm 132 is transmitted to a first space 111a.

[0036] According to an embodiment, the guide portion 142 may extend along at least a portion of the perimeter of at least one speaker 130. For example, the guide portion 142 may extend within the housing 110 along at least a portion of the side surface 130c of at least one speaker 130. For example, the guide portion 142 may extend between at least a portion of the side surface 130c of at least one speaker 130 and the housing 110. For example, when the housing 110 is viewed in a direction facing the first surface 130a (e.g., the -z direction), the guide portion 142 may be disposed (or positioned) between at least one speaker 130 and the vent 114.

[0037] According to an embodiment, the guide portion 142 may include a first portion 142a and a second portion 142b. The first portion 142a may contact the housing 110. The second portion 142b may be spaced apart from the first portion 142a by a specified distance. For example, the second portion 142b may be spaced apart from the first portion 142a by a specified distance along the circumferential direction of the housing 110. The second portion 142b may be spaced apart from the housing 110. The second portion 142b may be spaced apart from the housing 110 along the circumferential direction of the housing 110. For example, the second portion 142b may be spaced apart from the housing 110 along the circumferential direction of at least one speaker 130. For example, the second portion 142b may be spaced apart from the housing 110 while facing the housing 110 in the direction facing the first surface 130a (e.g., the -z direction). Since the second portion 142b and the housing 110 are spaced apart from each other, a gap g1 may be positioned (or formed) between the housing 110 and the second portion 142b. The gap g1 can provide a channel through which second audio can be transmitted to the first space 111a. The gap g1 can be connected to the first space 111a in the housing 110, and at least one speaker 130 is disposed in the first space 111a.

The inner surface 142c may face at least a portion of the side surface 130c of at least one speaker 130. The inner surface 142c may extend along at least a portion of the side surface 130c of at least one speaker 130. The inner surface 142c may surround (or enclose) at least a portion of the first space 111a. The inner surface 142c may face the axis a1 of the housing 110. The outer surface 142d may be opposite to the inner surface 142c. For example, the direction facing the outer surface 142d may be opposite to the direction facing the inner surface 142c, but is not limited thereto. For example, the outer surface 142d may be spaced apart from the inner surface 142c along the radiation direction of the housing 110. The radiation direction may refer to a direction away from the axis (or center) of the component, and unless otherwise stated, the corresponding expressions may be used substantially the same. For example, the outer surface 142d may be spaced apart from the inner surface 142c along the radiation direction of at least one speaker 130. According to an embodiment, the attachment surface 142e may contact the housing 110. The attachment surface 142e may be attached to the housing 110. The attachment surface 142e may face the direction in which the first surface 130a faces (e.g., the -z direction). For example, the attachment surface 142e may be substantially perpendicular to at least one of the inner surface 142c and the outer surface 142d, but is not limited thereto. A first side surface 142f may be disposed between the inner surface 142c and the outer surface 142d. For example, when viewing the housing 110 along the direction in which the first surface 130a faces (e.g., the -z direction), the first side surface 142f may be disposed between the inner surface 142c and the outer surface 142d. For example, when viewing the housing 110 along the direction in which the first surface 130a faces (e.g., the -z direction), the first side surface 142f may connect the inner surface 142c and the outer surface 142d. The second side surface 142g can be disposed between the inner surface 142c and the outer surface 142d. For example, when viewing the housing 110 along the direction facing the first surface 130a (e.g., the -z direction), the second side surface 142g can be disposed between the inner surface 142c and the outer surface 142d. For example, when viewing the housing 110 along the direction facing the first surface 130a (e.g., the -z direction), the second side surface 142g can connect the inner surface 142c and the outer surface 142d. The second side surface 142g can be opposite to the first side surface 142f. For example, the direction facing the second side surface 142g can be opposite to the direction facing the first side surface 142f. The second side surface 142g can be spaced apart from the first side surface 142f. The second side surface 142g can be located between the gap g1 and the housing 110.

[0039] According to an embodiment, the position of the first portion 142a can represent the position among the positions of the outer surface 142d, the first side surface 142f, and the second side surface 142g of the guide portion 142 that contacts the housing 110. For example, the position of the first portion 142a can represent the position among the positions of the outer surface 142d of the guide portion 142 that contacts the housing 110. However, it is not limited to this; the position of the first portion 142a can also represent the position among the positions of the first side surface 142f that contacts the housing 110. According to an embodiment, the second portion 142b can include the second side surface 142g of the guide portion 142. For example, the position of the second portion 142b can represent the second side surface 142g of the guide portion 142.

[0040] According to an embodiment, the electronic device 100 may include a second audio path 180. The second audio path 180 may be located (or formed) between the guide portion 142 and the housing 110. The second audio path 180 may extend (or be formed) along at least a portion of the side surface 130c of at least one speaker 130. The second audio path 180 may be located between the outer surface 142d of the guide portion 142 and the housing 110. For example, the second audio path 180 may be formed by pressing the outer surface 142d of the guide portion 142 inward, but is not limited thereto. The second audio path 180 may connect to the gap g1 between the second portion 142b and the housing 110. The second audio path 180 may extend from the gap g1 to the vent 114, such that a second audio signal from the second surface 130b passing through the gap g1 is emitted to the vent 114. When the second audio path 180 is formed through the guide portion 142, the path of movement of the second audio signal from the second surface 130b to the vent 114 may be increased. For example, since the first portion 142a of the guide portion 142 contacts the housing 110, the audio transmitted to the first space 111a after passing through the second surface 130b can be transmitted to the vent 114 only through the gap g1. Because the second audio is transmitted to the vent 114 only through the gap g1, the movement path of the second audio from the second surface 130b to the vent 114 can be relatively increased compared to the case where the guide portion 142 is omitted. As the movement path of the second audio increases, the volume of the second audio transmitted to the vent 114 can decrease. As the volume of the second audio transmitted to the vent 114 decreases, the volume of the second audio received by the microphone 170 after passing through the vent 114 can also decrease.

[0041] According to an embodiment, the vent 114 may be close to (or adjacent to) the first portion 142a of the first portion 142a and the second portion 142b. When the vent 114 is closer to the first portion 142a that contacts the housing 110, the movement path of the second audio signal from the second surface 130b to the vent 114 can be relatively increased compared to when the vent 114 is closer to the second portion 142b. When the movement path of the second audio signal is relatively increased, the magnitude of the second audio signal received by the microphone 170 after passing through the vent 114 can be reduced.

[0042] As described above, the electronic device 100 according to the embodiment can provide a structure for reducing the magnitude of a second audio signal received by the microphone 170 after passing through the vent 114 via the guide portion 142, which relatively increases the movement path of the second audio signal from the second surface 130b to the vent 114.

For example, the major axis 114a of the vent 114 may be substantially perpendicular to the axis a1 of the housing 110, but is not limited thereto. For example, the angle between the major axis 114a of the vent 114 and the axis a1 of the housing 110 may be an obtuse angle.

[0046] According to an embodiment, the location of the first portion 142a of the guide portion 142 may include a corner 142h in the guide portion 142. For example, the location of the first portion 142a of the guide portion 142 may represent a corner 142h in the guide portion 142 where a first side surface 142f and an outer surface 142d contact (or connect). According to an embodiment, the second portion 142b may include a second side surface 142g of the guide portion 142. For example, the location of the second portion 142b may represent the second side surface 142g of the guide portion 142.

The distance between the vent 114 and the first portion 142a can represent the straight-line distance from the vent 114 to the first portion 142a. The distance between the vent 114 and the second portion 142b can represent the straight-line distance from the vent 114 to the second portion 142b.
