According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service.

The acoustic pipe may be an audio path through which the first audio signal moves, as a hole passing through the nozzle 230.
According to an embodiment, the housing 210 may include a first surface 210a facing a first direction d1 in which a transmission path of the first audio signal is extended and a second surface 210b including an opening 211 facing a second direction d2 different from the first direction d1.

The second surface 210b may be a curved surface convexly formed in the second direction d2. The first surface 210a may face the second surface 210b, and an edge of the first surface 210a may contact an edge of the second surface 210b.
According to an embodiment, the first surface 210a may be a surface in which the nozzle 230 extended in the first direction d1 protrudes. The second surface 210b may include the opening 211 facing the second direction d2. A portion of the grill 220 (e.g., a mesh pattern 221 and/or a frame 223) may be inserted into the opening 211. A second audio signal may be conducted into the inside of the wearable device 100 through the opening 211. The second audio signal may be an audio signal transmitted to the microphone 226.
According to an embodiment, the microphone 226 in the housing 210 may face the opening 211. The microphone 226 may obtain the second audio signal through the opening 211. The second audio signal may be distinct from the first audio signal. The second audio signal may be an acoustic signal conducted from the outside.

According to an embodiment, the grill 220 may surround the opening 211. The grill 220 may have a shape corresponding to the opening 211. The grill 220 may be disposed to across the inner space of the wearable device 100 connected to the opening 211 and the outside. The grill 220 may include a conductive portion. For example, the entire grill 220 may be formed of a conductive portion, and a portion of the grill 220 may be formed of the conductive portion. The conductive portion may be formed of a metal, which is capable of conducting current and has rigidity. The conductive portion may include stainless steel. The grill 220 may prevent/reduce air flowing around the wearable device 100 from flowing into the microphone 226 through the opening 211. For example, the grill 220 may disperse the air flow or scatter the air, while the air passes through the opening 211.

According to an embodiment, the grill 220 may include a mesh pattern 221, a supporter (e.g., a support) 222, and/or a frame 223. The mesh pattern 221 may have a shape corresponding to a cross-section of the opening 211. For example, the mesh pattern 221 may be formed to sufficiently surround the entire opening 211. According to an embodiment, the grill 220 may further include the frame 223 disposed between the opening 211 and the mesh pattern 221. The frame 223 may be in contact with inside of the opening 211 along an edge of the opening 211. The frame 223 may extend along an edge of the mash pattern 221, and define an appearance of the mesh pattern 221. The supporter 222 may support the mash pattern 221 and the frame 223. The supporter 222 may be attached to an inner surface of the housing 210. The mash pattern 221 fixed or supported by the supporter 222 may cover the cross-section of the opening 211. The supporter 222 may be disposed along the edge of the opening 211 formed in the housing 210. The supporter 222 may be attached to the edge of the opening 211 of the housing 210. A partial area of the housing 210 to which the supporter 222 is attached may form a continuous surface with the inner surface, but is not limited thereto. For example, a partial area of the housing 210 may form a recess or a groove. The supporter 222 may be seated in the recess or the groove.
According to an embodiment, the mesh pattern 221 may be formed as a curved surface corresponding to the second surface 210b. The mesh pattern 221 may be disposed in the opening 211. The mesh pattern 221 may protrude from the supporter 222 in the second direction d2. The frame 223 may be positioned between the mesh pattern 221 and the supporter 222. The frame 223 may extend in the second direction d2 along a side surface of the opening 211. A distance between the mesh pattern 221 and the printed circuit board 260 may be different from a distance between the supporter 222 and the printed circuit board 260. The frame 223 may connect the mesh pattern 221 and the supporter 222. The frame 223 may be inserted into the opening 211, and the supporter 222 may be attached to the inner surface of the housing 210. The frame 223 and the supporter 222 may be coupled to the housing 210, so that the grill 220 may be attached to the housing 210.
According to an embodiment, a current may flow through an entire area of the grill 220. The grill 220 may include the mash pattern 221, the supporter 222, and/or the frame 223, which are formed of a conductive material. The grill 220 formed of the conductive material may be connected to the conductive pattern 250 to function as an antenna element. For example, the grill 220 and the conductive pattern 250 may be fed through a feeder to transmit an electromagnetic wave to the outside of the wearable device 100. According to an embodiment, the conductive pattern 250 may be disposed on a portion of the inner surface of the housing 210. For example, the conductive pattern 250 may have a shape corresponding to the inner surface of the housing 210. The conductive pattern 250 may be attached to the inner surface of the housing 210. However, the disclosure is not limited thereto, and the conductive pattern 250 may be printed on a carrier formed of a non-conductive portion. The conductive pattern 250 may be disposed to face an inner surface of the housing 210. For another example, the carrier and the conductive pattern 250 may be referred to as a laser direct structuring antenna (LDS antenna). The carrier may be a resin (e.g., polycarbonate). The conductive pattern 250 may be printed in a groove formed on the resin through laser processing.
According to an embodiment, a partial area of the grill 220 may include a conductive portion through which the current may flow, and a remaining area of the grill 220 may include a non-conductive portion. For example, the non-conductive portion may be the mesh pattern 221, and the conductive portion may be the supporter 222. The supporter 222 may be electrically connected to the conductive pattern 250 and function as an antenna element.
According to an embodiment, a radiation extent of the antenna may increase by being coupled with a conductive portion (e.g., at least a portion of the grill 220) disposed around the conductive pattern 250. An antenna performance may be improved by the increased extent of the antenna radiator. For example, an electrical length of the antenna required in a low frequency band may be secured by connection of the conductive pattern 250 and the conductive portion around the conductive pattern 250. A gain of the antenna may increase by the increased extent of the antenna radiator. When only the conductive pattern 250 functions as an antenna, a radiation extent of the antenna element may be an area A1. When both the conductive pattern 250 and the grill 220 function as an antenna, a radiation extent of the antenna element may be an area A2. When the conductive pattern 250 functions as an antenna, the conductive portion disposed around the conductive pattern 250 may be coupled or cause parasitic capacitance, by electromagnetic interaction with the conductive pattern 250. The conductive portion may distort a signal radiated from the conductive pattern 250. According to an embodiment, the conductive pattern 250 may be electrically connected to the mesh pattern 221, the supporter 222, or the frame 223, which are the conductive portion, so that the distortion of the signal radiated from the antenna element and/or the grill may be reduced or an output of the radiated signal may be improved. For example, the conductive portion (e.g., the conductive portion of the grill 220) that causes the parasitic capacitance may be used as a conductive pattern to reduce the distortion of the signal. Based on the electrical connection between the mesh pattern 221, the supporter 222, or the frame 223, which are the conductive portions, the conductive pattern 250 may provide an electrical length for securing the performance of the antenna.
According to an embodiment, the conductive pattern 250 is electrically connected to at least one portion of the frame 223 including the supporter 222 or the conductive portion, so that the output of the signal radiated from the antenna element and/or the grill may be improved.
According to an embodiment, the conductive pattern 250 may be connected to the conductive portion of the grill 220. The conductive pattern 250 may include a body portion 251, an extension portion 252, and a bridge 253. The body portion 251 may determine a shape of the conductive pattern 250. An antenna structure of the conductive pattern 250 may be determined according to a shape of the body portion 251 or a connection shape with the grill 220. For example, based on the shape of the body portion 251 or the connection shape with the grill 220, the conductive pattern 250 may function as a patch antenna, a monopole antenna, a F antenna, an inverted F antenna, or a dipole antenna. However, the disclosure is not limited thereto.
According to an embodiment, the conductive pattern 250 may be disposed in the inner surface of the housing 210. The conductive pattern 250 may be disposed in an inner surface facing the second surface of the housing 210 in which the opening 211 is formed. The conductive pattern 250 may function as an antenna by being fed from the feeder. The conductive pattern 250 may receive power from a wireless communication circuit, and emit the electromagnetic wave to the outside of the wearable device 100.
