Depending on the embodiment, the electronic device 101 can communicate with the electronic device 104 via the server 108. Depending on the embodiment, the electronic device 101 may include a processor 120, a memory 130, an input module 150, an audio output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connection terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, and / or an antenna module 197. In some embodiments, at least one of the aforementioned components (e.g., the connection terminal 178) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101. In some embodiments, some of the above-described components (eg, sensor module 176 , camera module 180 , or antenna module 197 ) may be implemented as a single integrated component (eg, display module 160 ).

[0025] The processor 120 may execute, for example, software (e.g., program 140) to control at least one other component of the electronic device 101 connected to the processor 120 (e.g., a hardware component or a software component), and may perform various data processing or calculations. According to an embodiment, as at least part of the data processing or calculation, the processor 120 may store commands or data received from another component (e.g., sensor module 176 or communication module 190) in the volatile memory 132, process the commands or data stored in the volatile memory 132, and store the resulting data in the non-volatile memory 134. According to an embodiment, the processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)) or an auxiliary processor 123 (e.g., a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is independent of or integrated with the main processor 121. For example, when the electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121 or be adapted to be dedicated to a specific function. The auxiliary processor 123 may be implemented separately from the main processor 121 or as part of the main processor 121.

[0026] When the main processor 121 is inactive (e.g., sleeping), the auxiliary processor 123 (rather than the main processor 121) may control at least some of the functions or states associated with at least one of the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190). Alternatively, when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 may work with the main processor 121 to control at least some of the functions or states associated with at least one of the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190). Depending on the embodiment, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component functionally related to the auxiliary processor 123 (e.g., the camera module 180 or the communication module 190). Depending on the embodiment, the auxiliary processor 123 (e.g., a neural processing unit) may include hardware structures dedicated to artificial intelligence model processing. The artificial intelligence model may be generated through machine learning. For example, such learning may be performed by the electronic device 101 where the artificial intelligence is executed or via a separate server (e.g., server 108). The learning algorithm may include, but is not limited to, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. The artificial intelligence model may include multiple artificial neural network layers. The artificial neural network may be a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), or a deep Q network or a combination of two or more thereof, but is not limited thereto. Additionally or alternatively, the artificial intelligence model may include a software structure in addition to a hardware structure.

[0027] The memory 130 may store various data used by at least one component of the electronic device 101 (e.g., the processor 120 or the sensor module 176). This various data may include, for example, software (e.g., the program 140) and input data or output data for commands associated therewith. The memory 130 may include a volatile memory 132 or a non-volatile memory 134.

[0028] The program 140 may be stored as software in the memory 130 , and may include, for example, an operating system (OS) 142 , middleware 144 , or applications 146 .

[0029] The input module 150 may receive commands or data from outside the electronic device 101 (e.g., a user) to be used by other components of the electronic device 101 (e.g., the processor 120). The input module 150 may include, for example, a microphone, a mouse, a keyboard, keys (e.g., buttons), or a digital pen (e.g., a stylus).

[0030] The sound output module 155 can output sound signals to the outside of the electronic device 101. The sound output module 155 can include, for example, a speaker or a receiver. The speaker can be used for general purposes such as playing multimedia or playing records. The receiver can be used to receive incoming calls. Depending on the embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0031] The display module 160 can visually provide information to the outside of the electronic device 101 (e.g., a user). The display device 160 may include, for example, a display, a holographic device, or a projector, and a control circuit for controlling a corresponding one of the display, the holographic device, and the projector. Depending on the embodiment, the display module 160 may include a touch sensor adapted to detect a touch or a pressure sensor adapted to measure the strength of the force caused by the touch.

[0032] The audio module 170 can convert sound into an electrical signal, and vice versa. Depending on the embodiment, the audio module 170 can obtain sound via the input module 150, or output sound via the sound output module 155 or an earphone of an external electronic device (e.g., electronic device 102) directly (e.g., wired) or wirelessly connected to the electronic device 101.

[0033] The sensor module 176 can detect the operating state of the electronic device 101 (e.g., power or temperature) or the environmental state outside the electronic device 101 (e.g., the state of the user), and then generate an electrical signal or data value corresponding to the detected state. Depending on the embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illumination sensor.

[0034] The interface 177 may support one or more specific protocols to be used to connect the electronic device 101 directly (e.g., wired) or wirelessly to an external electronic device (e.g., the electronic device 102). Depending on the embodiment, the interface 177 may include, for example, a High-Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, a Secure Digital (SD) card interface, or an audio interface.

[0035] The connection end 178 may include a connector, wherein the electronic device 101 can be physically connected to an external electronic device (e.g., the electronic device 102) via the connector. Depending on the embodiment, the connection end 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0036] The haptic module 179 may convert the electrical signal into mechanical stimulation (eg, vibration or motion) or electrical stimulation that can be recognized by the user via his sense of touch or kinesthetic sense. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0037] The camera module 180 may capture still images or moving images. According to an embodiment, the camera module 180 may include one or more lenses, image sensors, image signal processors, or flashes.

[0038] The power management module 188 may manage power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as, for example, at least a part of a power management integrated circuit (PMIC).

[0039] The battery 189 may power at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0040] The communication module 190 can support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and support direct (e.g., wired) communication or wireless communication. Depending on the embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0041] The wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (e.g., New Radio (NR) access technology). NR access technology can support enhanced mobile broadband (eMBB), massive machine type communication (mMTC), or ultra-reliable low-latency communication (URLLC). The wireless communication module 192 can support high-frequency bands (e.g., millimeter wave bands) to achieve, for example, high data transmission rates. The wireless communication module 192 can support various technologies for ensuring performance in high-frequency bands, such as, for example, beamforming, massive multiple-input multiple-output (massive MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. The wireless communication module 192 can support various requirements specified in the electronic device 101, an external electronic device (e.g., electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate for implementing eMBB (e.g., 20 Gbps or greater), loss coverage for implementing mMTC (e.g., 164 dB or less), or U-plane latency for implementing URLLC (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or 1 ms or less round trip).

[0042] Antenna module 197 can transmit or receive signals or power to or from an external device (e.g., an external electronic device) outside of electronic device 101. Depending on the embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). Depending on the embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for the communication scheme used in a communication network (e.g., first network 198 or second network 199) may be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. Depending on the embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may also be formed as part of antenna module 197.

[0043] According to various embodiments, antenna module 197 may form a millimeter wave antenna module. According to embodiments, the millimeter wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and multiple antennas (e.g., array antennas), wherein the RFIC is disposed on or adjacent to a first surface (e.g., the bottom surface) of the printed circuit board and is capable of supporting a designated high frequency band (e.g., the millimeter wave band), and the multiple antennas are disposed on or adjacent to a second surface (e.g., the top surface or a side surface) of the printed circuit board and are capable of transmitting or receiving signals in the designated high frequency band.

[0044] At least some of the above components may be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transfer signals (e.g., commands or data) therebetween.

[0045] According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199. Each of the electronic device 102 or the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type than the electronic device 101. According to an embodiment, all or some operations to be executed on the electronic device 101 may be executed on one or more of the external electronic device 102, the external electronic device 104, or the server 108. For example, if the electronic device 101 should automatically execute a function or service or should execute a function or service in response to a request from a user or another device, the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service instead of executing the function or service, or the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service in addition to executing the function or service. The one or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or execute another function or service related to the request, and transmit the results of the execution to the electronic device 101. The electronic device 101 may provide the results as at least a partial response to the request, either with or without further processing. To this end, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technologies may be used, for example. The electronic device 101 may use distributed computing or mobile edge computing to provide ultra-low latency services. In another embodiment, the external electronic device 104 may include an Internet of Things (IoT) device. The server 108 may be an intelligent server that utilizes machine learning and / or neural networks. Depending on the embodiment, the external electronic device 104 or the server 108 may be included in the second network 199. The electronic device 101 may be used for intelligent services based on 5G communication technology or IoT-related technologies (e.g., smart homes, smart cities, smart cars, or healthcare).

[0046] Figure 2 is a schematic diagram illustrating an electronic device according to an embodiment.

[0047] refer to Figure 2 , according to the electronic device 200 of the embodiment (eg, Figure 1The electronic device 101 may include a housing 230 that forms the appearance of the electronic device 200. For example, the housing 230 may include a first surface (or front surface) 200A, a second surface (or rear surface) 200B, and a third surface (or side surface) 200C surrounding the space between the first surface 200A and the second surface 200B.

Figure 3 frame structure 240).

[0048] The electronic device 200 according to an embodiment may include a substantially transparent front plate 202. In an embodiment, the front plate 202 may form at least a portion of the first surface 200A. In an embodiment, the front plate 202 may include, for example, a polymer plate or a glass plate including various coatings, but is not limited thereto.

[0049] The electronic device 200 according to an embodiment may include a substantially opaque rear panel 211. In an embodiment, the rear panel 211 may form at least a portion of the second surface 200B. In an embodiment, the rear panel 211 may be formed of coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS) or magnesium), or a combination of at least two of the foregoing materials.

[0050] The electronic device 200 according to an embodiment may include a side frame structure (or side member) 218 ​​(eg, Figure 3 In an embodiment, the side frame structure 218 may be coupled to the front panel 202 and / or the rear panel 211 to form at least a portion of the third surface 200C. For example, the side frame structure 218 may form the entire third surface 200C. In another example, the side frame structure 218 may form the third surface 200C together with the front panel 202 and / or the rear panel 211.

[0051] Unlike the illustrated embodiment, when the third surface 200C is partially formed by the front plate 202 and / or the rear plate 211, the front plate 202 and / or the rear plate 211 may include an area that curves from its periphery toward the rear plate 211 and / or the front plate 202 and extends seamlessly. The extended areas of the front plate 202 and / or the rear plate 211 may be positioned at, for example, both ends of the long side of the electronic device 200, but are not limited to the above examples.

[0052] In an embodiment, the side frame structure 218 may include metal and / or polymer. In an embodiment, the rear panel 211 and the side frame structure 218 may be integrally formed and may include the same material (e.g., a metal material such as aluminum), but is not limited thereto. For example, the rear panel 211 and the side frame structure 218 may be formed in separate configurations and / or may include different materials.

[0053] In an embodiment, the electronic device 200 may include at least one of a display 201, audio modules 203, 204, 207, a sensor module (not shown), camera modules 205, 212, 213, a key input device 217, a light emitting device (not shown), and / or a connector hole 208. In an embodiment, the electronic device 200 may omit at least one component (e.g., the key input device 217 or the light emitting device (not shown)), or may further include another component.

[0054] In an embodiment, the display 201 (e.g., Figure 1 The display module 160 may be visibly exposed through a majority of the front panel 202. For example, at least a portion of the display 201 may be visible through the front panel 202 forming the first surface 200A. In an embodiment, the display 201 may be disposed on the rear surface of the front panel 202.

[0055] In an embodiment, the outer shape of the display 201 may be formed to be substantially the same as the outer shape of the front panel 202 adjacent to the display 201. In an embodiment, in order to expand the area in which the display 201 is visually exposed, the distance between the outer portion of the display 201 and the outer portion of the front panel 202 may be formed to be substantially the same.

[0056] In an embodiment, the display 201 (or the first surface 200A of the electronic device 200) may include a screen display area 201A. In an embodiment, the display 201 may provide visual information to the user via the screen display area 201A. In the illustrated embodiment, when the first surface 200A is viewed from the front, the screen display area 201A is shown as being spaced apart from the exterior of the first surface 200A and positioned within the interior of the first surface 200A, but the present invention is not limited thereto. In an embodiment, when the first surface 200A is viewed from the front, at least a portion of the perimeter of the screen display area 201A may substantially coincide with the perimeter of the first surface 200A (or the front panel 202).

[0057] In an embodiment, the screen display area 201A may include a sensing area 201B configured to acquire biometric information of a user. Here, "the screen display area 201A includes the sensing area 201B" can be understood to mean that at least a portion of the sensing area 201B may overlap the screen display area 201A. For example, the sensing area 201B (like other areas of the screen display area 201A) may refer to an area where visual information can be displayed by the display 201 and where biometric information of a user (e.g., fingerprint) can be acquired. In an embodiment, the sensing area 201B may be formed in the key input device 217.

[0058] In an embodiment, the display 201 may include a first camera module 205 (eg, Figure 1 In an embodiment, an opening may be formed in this area of ​​the display 201, and the first camera module 205 (e.g., a punch-hole camera) may be at least partially disposed in the opening so as to face the first surface 200A. For example, the screen display area 201A may surround at least a portion of the perimeter of the opening. In an embodiment, the first camera module 205 (e.g., an under-display camera (UDC)) may be disposed below the display 201 so as to overlap this area of ​​the display 201. For example, the display 201 may provide visual information to the user through this area, and the first camera module 205 may also capture images corresponding to a direction facing the first surface 200A through this area of ​​the display 201.

[0059] In an embodiment, the display 201 may be coupled to or disposed adjacent to a touch sensing circuit, a pressure sensor capable of measuring touch intensity (pressure), and / or a digitizer for detecting a magnetic field-type stylus.

[0060] In an embodiment, the audio modules 203, 204, and 207 (e.g., Figure 1 The audio module 170 may include microphone holes 203 and 204 and a speaker hole 207.

[0061] In an embodiment, the microphone holes 203 and 204 may include a first microphone hole 203 formed in a partial area of ​​the third surface 200C and a second microphone hole 204 formed in a partial area of ​​the second surface 200B. A microphone (not shown) for acquiring external sound may be provided inside the microphone holes 203 and 204. The microphone may include a plurality of microphones to detect the direction of the sound.

[0062] In an embodiment, the second microphone hole 204 formed in a partial area of ​​the second surface 200B may be disposed adjacent to the camera modules 205, 212, and 213. For example, the second microphone hole 204 may capture sound according to the operation of the camera modules 205, 212, and 213. However, the present invention is not limited thereto.

[0063] In an embodiment, the speaker hole 207 may include an external speaker hole 207 and a receiver hole for calls (not shown). The external speaker hole 207 may be formed on a portion of the third surface 200C. In an embodiment, the external speaker hole 207 may be implemented as a single hole with the microphone hole 203. Although not shown, the receiver hole for calls (not shown) may be formed on another portion of the third surface 200C. For example, the receiver hole for calls may be formed on the opposite side of the external speaker hole 207 on the third surface 200C. For example, based on Figure 2As shown in FIG, the external speaker hole 207 may be formed on the third surface 200C corresponding to the lower end of the electronic device 200, and the receiver hole for calls may be formed on the third surface 200C corresponding to the upper end of the electronic device 200. However, the present invention is not limited to this, and in some embodiments, the receiver hole for calls may be formed in a location other than the third surface 200C.

[0076] In an embodiment, the frame structure 240 may include a structure forming the appearance of the electronic device 200 (eg, Figure 2 The frame structure 240 includes a sidewall 241 (surface 200B) and a support portion 243 extending inward from the sidewall 241. In an embodiment, the frame structure 240 may be disposed between the display 201 and the rear panel 211. In an embodiment, the sidewall 241 of the frame structure 240 may surround the space between the rear panel 211 and the front panel 202 (and / or the display 201), and the support portion 243 of the frame structure 240 may extend from the sidewall 241 within the space.

[0077] In embodiments, the frame structure 240 may support or accommodate other components included in the electronic device 200. For example, the display 201 may be disposed on one surface of the frame structure 240 facing one direction (e.g., the +z direction), and the display 201 may be supported by the support portion 243 of the frame structure 240. For another example, the first printed circuit board 250, the second printed circuit board 252, the battery 270, and the second camera module 212 may be disposed on another surface of the frame structure 240 facing a direction opposite to the one direction (e.g., the -z direction). The first printed circuit board 250, the second printed circuit board 252, the battery 270, and the second camera module 212 may be mounted in a recess defined by the sidewall 241 and / or the support portion 243 of the frame structure 240.

[0078] In an embodiment, the first printed circuit board 250, the second printed circuit board 252, and the battery 270 may be coupled to the frame structure 240. For example, the first printed circuit board 250 and the second printed circuit board 252 may be fixedly mounted in the frame structure 240 using coupling members such as screws. For example, the battery 270 may be fixedly mounted on the frame structure 240 using an adhesive member (e.g., double-sided tape). However, the present invention is not limited to the above example.

[0079] In an embodiment, the cover plate 260 may be disposed between the first printed circuit board 250 and the rear plate 211. In an embodiment, the cover plate 260 may be disposed on the first printed circuit board 250.

In an embodiment, the cover plate 260 may cover at least a portion of the first printed circuit board 250. In this manner, the cover plate 260 may protect the first printed circuit board 250 from physical impact or prevent a connector coupled to the first printed circuit board 250 from detaching.

[0081] In an embodiment, the cover plate 260 may be fixedly disposed on the first printed circuit board 250 by a coupling member (eg, a screw), or may be coupled to the frame structure 240 together with the first printed circuit board 250 by a coupling member.

[0082] In an embodiment, the display 201 may be disposed between the frame structure 240 and the front plate 202. For example, the front plate 202 may be disposed on one side of the display 201 (eg, +z direction) and the frame structure 240 may be disposed on the other side (eg, -z direction).

[0083] In an embodiment, the front plate 202 may be coupled to the display 201. For example, the front plate 202 and the display 201 may be bonded to each other with an optical bonding member (eg, optically clear adhesive (OCA) or optically clear resin (OCR)) interposed therebetween.

[0084] In an embodiment, the front panel 202 may be coupled to the frame structure 240. For example, when viewed in the z-axis direction, the front panel 202 may include an outer portion extending outside the display 201, and may be bonded to the frame structure 240 by an adhesive member (e.g., double-sided tape) disposed between the outer portion of the front panel 202 and the frame structure 240 (e.g., the sidewall 241). However, the present invention is not limited to the above example.

[0085] In an embodiment, the first printed circuit board 250 and / or the second printed circuit board 252 may be equipped with a processor (eg, Figure 1 processor 120), memory (e.g., Figure 1 Memory 130) and / or interfaces (e.g., Figure 1 Interface 177). The processor may include, for example, one or more of a central processing unit, an application processor, a graphics processing unit, an image signal processor, a sensor hub processor, or a communication processor. The memory may include, for example, a volatile memory or a non-volatile memory. The interface may include, for example, a high-definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and / or an audio interface. The interface may electrically or physically connect the electronic device 200 to an external electronic device and may include a USB connector, an SD card / MMC connector, or an audio connector. In an embodiment, the first printed circuit board 250 and the second printed circuit board 252 may be operably connected or electrically connected to each other via a connecting member (e.g., a flexible printed circuit board).

[0086] In an embodiment, the battery 270 can supply power to at least one component of the electronic device 200. For example, the battery 270 can include a rechargeable secondary battery or a fuel cell. At least a portion of the battery 270 can be disposed on substantially the same plane as the first printed circuit board 250 and / or the second printed circuit board 252.

[0087] The electronic device 200 according to an embodiment may include an antenna module (not shown) (eg, Figure 1 Antenna module 197). In embodiments, the antenna module may be disposed between rear panel 211 and battery 270. The antenna module may include, for example, a near-field communication (NFC) antenna, a wireless charging antenna, and / or a magnetic secure transmission (MST) antenna. For example, the antenna module may enable short-range communication with an external device or wirelessly transmit and receive power to and from an external device.

[0088] In an embodiment, the first camera module 205 (eg, a front camera) may be disposed in at least a portion of the frame structure 240 (eg, the support portion 243 ) so that the lens may be viewed through a portion of the front panel 202 (eg, Figure 2 The camera area 237) receives external light.

[0089] In an embodiment, a second camera module 212 (e.g., a rear camera) may be disposed between the frame structure 240 and the rear panel 211. In an embodiment, the second camera module 212 may be electrically connected to the first printed circuit board 250 via a connection member (e.g., a connector). In an embodiment, the second camera module 212 may be disposed so that the lens can receive external light through the camera region 284 of the rear panel 211 of the electronic device 200.

[0090] In an embodiment, the camera area 284 may be formed on a surface of the rear plate 211 (eg, Figure 2 200B). In an embodiment, the camera region 284 may be formed to be at least partially transparent so that external light can be incident on the lens of the second camera module 212. In an embodiment, at least a portion of the camera region 284 may protrude from the surface of the rear plate 211 to a predetermined height. However, the present invention is not limited thereto, and in an embodiment, the camera region 284 may form a substantially flat surface with the surface of the rear plate 211.

[0091] In an embodiment, the housing 230 of the electronic device 200 may refer to a configuration or structure that forms at least a portion of the appearance of the electronic device 200. In this regard, at least a portion of the front plate 202, the frame structure 240, and / or the rear plate 211 that form the appearance of the electronic device 200 may be referred to as the housing 230 of the electronic device 200.

[0092] Figure 4 is a diagram showing an exemplary electronic device being Figure 2 Cross-sectional view of an example of line cutting of AA'.

[0093] refer to Figure 4 , according to the electronic device 200 of the embodiment (eg, Figure 1 The electronic device 101 may include a housing 230 (eg, Figure 3 frame structure 240 ) and / or speaker module 400 .

[0094] According to an embodiment, the housing 230 may provide an appearance of the electronic device 200. For example, the housing 230 may form at least a portion of the appearance of the electronic device 200. For example, the housing 230 may accommodate components of the electronic device 200. For example, the housing 230 may provide an interior space in which the components of the electronic device 200 are disposed. For example, the speaker module 400 may be disposed in the housing 230.

[0095] According to an embodiment, the housing 230 may include a speaker hole 207. For example, audio output from the speaker module 400 may be transmitted to the outside of the housing 230 (or the outside of the electronic device 200) through the speaker hole 207. The speaker hole 207 may penetrate a portion of the housing 230. For example, the speaker hole 207 may penetrate a portion of the frame structure 240 in the housing 230. For example, the speaker hole 207 may penetrate the outer surface 230a of the housing 230. The outer surface 230a of the housing 230 may refer to a surface of the housing 230 that is exposed to the outside. For example, the outer surface 230a of the housing 230 may be provided on the first surface 200A (e.g., Figure 2 a first surface 200A) and a second surface 200B (eg, Figure 2 The outer surface 230a of the housing 230 may connect the first surface 200A of the housing 230 and the second surface 200B of the housing 230. However, the present invention is not limited thereto. For example, the speaker hole 207 may have a shape provided on a display (e.g., Figure 2 and Figure 3 The shape of the gap between the display 201) and the housing 230.

[0096] According to an embodiment, the speaker module 400 may include a speaker 410 , at least one housing 420 , an audio path 430 , a resonance space 440 , a plurality of adsorption sheets 450 , at least one air gap 460 and / or at least one attachment member 470 .

[0097] Depending on the embodiment, the speaker 410 may be configured to output audio to provide auditory information to the user. For example, the speaker 410 may be configured to output audio through the first surface 410a of the speaker 410. A hole for transmitting the audio output from the speaker 410 may be provided (or formed) on the first surface 410a of the speaker 410. The second surface 410b of the speaker 410 may be opposite to the first surface 410a. For example, the direction facing the second surface 410b of the speaker 410 (e.g., the +z direction) may be opposite to the direction facing the first surface 410a of the speaker 410 (e.g., the -z direction). For example, the second surface 410b of the speaker 410 may be spaced apart from the first surface 410a of the speaker 410 in the direction facing the second surface 410b (e.g., the +z direction). Depending on the embodiment, the speaker 410 may include a diaphragm, a coil, and / or a magnet. For example, the diaphragm of the speaker 410 may be provided on the first surface 410a of the speaker 410. For example, the diaphragm of speaker 410 may form at least a portion of the first surface 410a of speaker 410. The coil of speaker 410 may be coupled to the diaphragm disposed on the first surface 410a of speaker 410. For example, the coil of speaker 410 may be disposed within speaker 410. The magnet of speaker 410 may be disposed within speaker 410. The magnet in speaker 410 may apply a magnetic field to the coil of speaker 410. For example, when current is applied to the coil of speaker 410, a magnetic field may be generated by the coil of speaker 410. The magnetic field generated by the application of current to the coil of speaker 410 may interact with the magnetic field generated by the magnet. As the magnetic field generated by the current applied to the coil interacts with the magnetic field generated by the magnet, the coil and the diaphragm coupled to the coil may vibrate at a specified frequency. For example, the diaphragm of speaker 410 may be vibrated by the coil vibrating in the direction facing the first surface 410a of speaker 410 (e.g., the -z direction) or in the direction facing the second surface 410b of speaker 410 (e.g., the +z direction). As the air adjacent to the diaphragm in the speaker module 400 vibrates due to the vibration of the diaphragm of the speaker 410, audio may be generated. According to an embodiment, the speaker 410 may be provided in the housing 230. The speaker 410 may be provided inside at least one housing 420 in the speaker module 400. The speaker 410 may be accommodated inside the at least one housing 420.

[0098] According to an embodiment, at least one housing 420 may provide the exterior appearance of the speaker module 400. The at least one housing 420 may surround (or cover) the speaker 410. According to an embodiment, the at least one housing 420 may include a first housing 421 and a second housing 422. The speaker 410 may be disposed within the first housing 421 and the second housing 422. The first housing 421 may surround (or enclose) a portion of the speaker 410. For example, the first housing 421 may surround (or enclose) the first surface 410a of the speaker 410. For example, at least a portion of the first housing 421 may be disposed to correspond to the first surface 410a of the speaker 410. The second housing 422 may surround (or enclose) another portion of the speaker 410. For example, at least a portion of the second housing 422 may be disposed to correspond to the second surface 410b of the speaker 410. For example, the second housing 422 may surround (or enclose) the second surface 410b of the speaker 410. The second housing 422 may be coupled to the first housing 421. For example, the second housing 422 may be connected to the first housing 421. However, the present invention is not limited thereto, and the first housing 421 may be integrally formed with the second housing 422 .

[0099] According to an embodiment, the audio path 430 can output audio from the speaker 410 to the exterior of the housing 230. The audio path 430 can provide a path through which the audio from the speaker 410 can move to the exterior of the housing 230. For example, the audio path 430 can be provided on the first surface 410a of the speaker 410 that outputs the audio. For example, the audio path 430 can be in contact with the first surface 410a of the speaker 410. For example, the audio path 430 can extend from the first surface 410a of the speaker 410 toward the speaker hole 207 of the housing 230. According to an embodiment, the audio path 430 can be surrounded (or enclosed) by at least one housing 420. For example, the audio path 430 can be surrounded (or enclosed) by the first housing 421 and / or the second housing 422. The audio path 430 can connect the space within the at least one housing 420 with the exterior of the housing 230. For example, the audio path 430 can connect the space within the at least one housing 420 with the speaker hole 207. Audio output through the first surface 410 a of the speaker 410 may move along the audio path 430 to the speaker hole 207 and then be output to the outside of the housing 230 .

[0100] Depending on the embodiment, the resonance space 440 can provide resonance for the audio output by the diaphragm of the speaker 410. For example, the resonance space 440 can provide a space for the back volume of the audio from the speaker 410. Depending on the embodiment, the resonance space 440 can be separated from the audio path 430. The resonance space 440 can be disconnected from the audio path 430. For example, when audio is output from the speaker 410, the entire speaker 410 can vibrate due to the vibration generated by the diaphragm of the speaker 410. Due to the vibration of the speaker 410, another audio with a phase opposite to the phase of the audio output through the first surface 410a of the speaker 410 can be output through the second surface 410b of the speaker 410. When the audio path 430 and the resonance space 440 are connected to each other, destructive interference may occur between the audio output through the first surface 410a of the speaker 410 and the other audio output through the second surface 410b of the speaker 410. Resonance space 440 can reduce destructive interference between audio output through first surface 410a and other audio output through second surface 410b by disconnecting it from audio path 430, which is the path for audio output through first surface 410a. Depending on the embodiment, resonance space 440 may be disposed within at least one housing 420. For example, resonance space 440 may extend from second surface 410b of speaker 410 within at least one housing 420. For example, at least a portion of resonance space 440 may be disposed on second surface 410b of speaker 410. For example, this portion of resonance space 440 may be in contact with second surface 410b of speaker 410. Depending on the embodiment, resonance space 440 may be sealed by at least one housing 420 and speaker 410. For example, resonance space 440 may be sealed by first housing 421, second housing 422, and / or speaker 410, disconnecting it from audio path 430. Depending on the embodiment, resonance space 440 may have a stepped shape. For example, the size of resonance space 440 may vary within at least one housing 420. For example, the shape of resonance space 440 may not correspond to the shape of speaker 410. For example, the thickness h1 of one region of resonance space 440 may be different from the thickness h2 of another region of the resonance space. The thickness of a component may refer to the distance in a direction (e.g., the +z direction and / or the -z direction) parallel to the direction (e.g., the -z direction) facing first surface 410a of speaker 410, and corresponding expressions may be used substantially the same below.

[0101] According to embodiments, the multiple adsorption sheets 450 can significantly expand the size of the resonance space 440 without increasing its physical size. For example, the multiple adsorption sheets 450 can adsorb at least a portion of the air in the resonance space 440. Since at least a portion of the air in the resonance space 440 is adsorbed by the multiple adsorption sheets 450, the size of the resonance space 440 can be significantly expanded. For example, each of the multiple adsorption sheets 450 can include a porous material having micropores that adsorb at least a portion of the air in the resonance space 440. For example, each of the multiple adsorption sheets 450 can include at least one of zeolite or activated carbon. For example, the multiple adsorption sheets 450 can have the form of a sheet without particles. For example, the multiple adsorption sheets 450 can have the shape of a plate (or plane) extending in a direction (e.g., +x, -x, +y, and / or -y) perpendicular to the direction (e.g., -z) facing the first surface 410a of the speaker 410. According to embodiments, the multiple adsorption sheets 450 can be disposed within the at least one housing 420. Multiple adsorption sheets 450 may be disposed in the resonance space 440. At least a portion of the multiple adsorption sheets 450 may be stacked on top of each other within the resonance space 440. For example, at least a portion of the multiple adsorption sheets 450 may be arranged in the direction facing the first surface 410a of the speaker 410 (e.g., the -z direction) or the direction facing the second surface 410b of the speaker 410 (e.g., the +z direction). For example, at least a portion of the multiple adsorption sheets 450 may be stacked in the direction facing the first surface 410a of the speaker 410 (e.g., the -z direction). For example, at least a portion of the multiple adsorption sheets 450 may be stacked in the direction facing the second surface 410b of the speaker 410 (e.g., the +z direction). For example, the thickness of each of the multiple adsorption sheets 450 may be 0.4 mm to 0.8 mm, but is not limited thereto. Depending on the embodiment, the multiple adsorption sheets 450 may be disconnected from each other. The multiple adsorption sheets 450 may be separated from each other. For example, the multiple adsorption sheets 450 may include a first adsorption sheet 451 and a second adsorption sheet 452 that are disconnected from each other. The second adsorption sheet 452 may be provided on the first adsorption sheet 451. In the following description, the first adsorption sheet 451 and the second adsorption sheet 452 may be used to refer to one of the plurality of adsorption sheets 450 and another of the plurality of adsorption sheets 450. Hereinafter, for example, the first adsorption sheet 451 is described as one of the plurality of adsorption sheets 450 adjacent to the support member 453, but the sheet referred to by the first adsorption sheet 451 may be different.

[0102] According to an embodiment, the first adsorption sheet 451 may be attached to the support member 453. For example, the first adsorption sheet 451 may be attached to the support member 453 via at least one adhesive member 454. The support member 453 may support the plurality of adsorption sheets 450 within the at least one housing 420. The support member 453 may include, but is not limited to, polyethylene terephthalate (PET). For example, the thickness of the support member 453 may be 0.05 mm, but is not limited thereto.

[0103] According to an embodiment, at least one adhesive member 454 may attach the support member 453 to the at least one housing 420. At least one adhesive member 454 may attach the support member 453 to the first adsorption sheet 451. For example, the at least one adhesive member 454 may include an adhesive material. For example, the thickness of the at least one adhesive member 454 between the at least one housing 420 and the support member 453 may be 0.03 mm, but is not limited thereto. For example, the thickness of the at least one adhesive member 454 between the support member 453 and the first adsorption sheet 451 may be 0.03 mm, but is not limited thereto.

[0104] Depending on the embodiment, the size of the second adsorption sheet 452 may differ from the size of the first adsorption sheet 451. For example, the thickness of the second adsorption sheet 452 may differ from the thickness of the first adsorption sheet 451. For example, the width of the second adsorption sheet 452 may differ from the width of the first adsorption sheet 451. For example, the width of the first adsorption sheet 451 may be greater than the width of the second adsorption sheet 452. The width of a component may refer to the distance in a direction (e.g., -y direction, +y direction) substantially perpendicular to the direction (e.g., -z direction) facing the first surface 410a of the speaker 410. The corresponding expressions may be used substantially the same unless otherwise stated below. For example, as the components installed in the electronic device 200 become more diverse, the shape of the space within the housing 230 in which the speaker module 400 is installed may also become more diverse. As the shape of the space within the housing 230 becomes more diverse, the shape of the resonance space 440 within the speaker module 400 may also become more diverse. For example, the thickness of the resonance space 440 may vary within at least one housing 420. If the multiple adsorption sheets 450 have the same size, the number (and / or size) of the multiple adsorption sheets 450 disposed in the resonance space 440 may be reduced. If the number (and / or size) of the multiple adsorption sheets 450 disposed in the resonance space 440 is reduced, the quality of the audio transmitted from the speaker 410 to the outside of the housing 230 may be reduced. Because the size of a portion (e.g., the first adsorption sheet 451) of the multiple adsorption sheets 450 disposed in the resonance space 440 is different from the size of another portion (e.g., the second adsorption sheet 452), the electronic device 200 according to an embodiment can provide a structure in which the overall shape of the multiple adsorption sheets 450 corresponds to the shape of the resonance space 440. Since the overall shape of the multiple adsorption sheets 450 corresponds to the shape of the resonance space 440, the number (and / or size) of the multiple adsorption sheets 450 disposed in the resonance space 440 can be increased compared to when the multiple adsorption sheets 450 have the same size. As the number (and / or size) of the multiple adsorption sheets 450 disposed in the resonance space 440 increases, the quality of the audio output to the outside of the housing 230 can be improved. However, it should be remembered that in the above description, the fact that the first adsorption sheet 451 and the second adsorption sheet 452 have different sizes does not necessarily mean that the sizes of the plurality of adsorption sheets 450 are different from each other. For example, when the size of the first adsorption sheet 451 (which is one of the plurality of adsorption sheets 450) is different from the size of the second adsorption sheet 452 (which is another adsorption sheet), the size of the other adsorption sheets in the plurality of adsorption sheets 450 may be substantially the same as that of one of the first adsorption sheet 451 and the second adsorption sheet 452.

[0105] Depending on the embodiment, the materials included in each of the plurality of adsorption sheets 450 may be different. For example, the material included in the first adsorption sheet 451 and the material included in the second adsorption sheet 452 may be different. Depending on the embodiment, each of the plurality of adsorption sheets 450 may include different materials depending on the distance from the speaker 410. For example, the porosity of each of the plurality of adsorption sheets 450 may vary depending on the distance from the speaker 410. Of the first adsorption sheet 451 and the second adsorption sheet 452, the speaker 410 may be closer to the first adsorption sheet 451. For example, the porosity of the first adsorption sheet 451, which is relatively close to the speaker 410, may be lower than the porosity of the second adsorption sheet 452, which is relatively far away from the speaker 410. For example, the first adsorption sheet 451 may be made of zeolite with a relatively low porosity, and the second adsorption sheet 452 may be made of activated carbon with a relatively high porosity, but the present invention is not limited thereto. For example, the closer the distance to the speaker 410, the higher the likelihood of damage from the vibrations generated by the speaker 410. As the porosity increases, the rigidity of the plurality of adsorption sheets 450 may decrease. Therefore, the porosity of the first adsorption sheet 451, which is relatively close to the speaker 410, may be lower than the porosity of the second adsorption sheet 452, which is relatively far from the speaker 410. Since the porosity of the first adsorption sheet 451 is relatively lower than that of the second adsorption sheet 452, the rigidity of the first adsorption sheet 451 may be higher than that of the second adsorption sheet 452.

[0106] According to embodiments, the at least one air gap 460 can increase contact between the plurality of adsorption sheets 450 and at least a portion of the air in the resonance space 440. For example, the at least one air gap 460 can increase the contact area between the plurality of adsorption sheets 450 and at least a portion of the air in the resonance space 440. According to embodiments, the at least one air gap 460 can be provided between the plurality of adsorption sheets 450. For example, the at least one air gap 460 can be interposed between the first adsorption sheet 451 and the second adsorption sheet 452. Since the at least one air gap 460 is interposed between the first adsorption sheet 451 and the second adsorption sheet 452, the contact area between the air in the resonance space 440 and the first adsorption sheet 451, as well as the contact area between the air in the resonance space 440 and the second adsorption sheet 452, can be increased. As each of the plurality of adsorption sheets 450 comes into easier contact with the air in the resonance space 440, the plurality of adsorption sheets 450 can easily adsorb at least a portion of the air in the resonance space 440.

[0107] According to an embodiment, at least one attachment member 470 may be interposed between the plurality of adsorption sheets 450. The at least one attachment member 470 may attach one of the plurality of adsorption sheets 450 (e.g., the first adsorption sheet 451) to another of the plurality of adsorption sheets 450 (e.g., the second adsorption sheet 452). The at least one attachment member 470 may separate each of the plurality of adsorption sheets 450. For example, since the at least one attachment member 470 is interposed between the first adsorption sheet 451 and the second adsorption sheet 452, the first adsorption sheet 451 and the second adsorption sheet 452 may be spaced apart from each other by a distance corresponding to the thickness of the at least one attachment member 470. For example, the at least one attachment member 470 may be in the form of a tape including an adhesive material, but is not limited thereto.

[0108] As described above, since the size of a portion of the plurality of adsorption sheets 450 is different from the size of another portion of the plurality of adsorption sheets 450 to correspond to the shape of the resonance space 440 (the thickness of which varies within the housing 420), the electronic device 200 according to the embodiment can provide a structure in which the quality of audio transmitted to the outside of the housing 230 is improved. Since at least one air gap 460 is provided between the plurality of adsorption sheets 450, the electronic device 200 according to the embodiment can provide a structure in which the contact area between the plurality of adsorption sheets 450 and the air in the resonance space 440 can be expanded.

[0109] Hereinafter, the plurality of adsorption sheets 450 will be described based on the first adsorption sheet 451 and the second adsorption sheet 452 , but the description of the first adsorption sheet 451 and the second adsorption sheet 452 can basically be applied to the rest of the plurality of adsorption sheets 450 .

[0110] Figure 5a is a perspective view showing a plurality of exemplary adsorption sheets. Figure 5b is an exploded perspective view showing a plurality of exemplary adsorption sheets.

[0111] refer to Figure 5a and Figure 5bAccording to embodiments, the first suction sheet 451 may include a first edge 451a, a second edge 451b, a third edge 451c, and / or a fourth edge 451d. The first edge 451a may extend in a first direction (e.g., the −y direction). The second edge 451b may be connected to the first edge 451a. For example, the second edge 451b may be connected to one end of the first edge 451a. For example, the second edge 451b may extend in a second direction (e.g., the +x direction) perpendicular to the first direction (e.g., the −y direction). The third edge 451c may be connected to the second edge 451b. The third edge 451c may be opposite to the first edge 451a. For example, the third edge 451c may be connected to the other end of the second edge 451b opposite to the end connected to the first edge 451a. For example, the third edge 451c may be parallel to the first edge 451a. For example, the third edge 451c may extend from the fourth edge 451d in the first direction (e.g., the −y direction). The fourth edge 451d may connect the first edge 451a and the third edge 451c. The fourth edge 451d may be opposite to the second edge 451b. For example, the fourth edge 451d may extend from the other end of the first edge 451a opposite to the end connected to the second edge 451b along the second direction (e.g., the +x direction) to the third edge 451c.

[0112] According to an embodiment, at least one attachment member 470 may include a first attachment member 471 and a second attachment member 472. The first attachment member 471 may be closer to the first corner 451e of the first suction sheet 451, between the first corner 451e and the second corner 451f opposite the first corner 451e. The first corner 451e may refer to the area of ​​the first suction sheet 451 where the first edge 451a and the fourth edge 451d contact each other. The second corner 451f may refer to another area of ​​the first suction sheet 451 where the second edge 451b and the third edge 451c contact each other. For example, the first attachment member 471 may be provided at the first corner 451e. The second attachment member 472 may be disconnected from the first attachment member 471. The second attachment member 472 may be disconnected from the first attachment member 471. The second attachment member 472 may be closer to the second corner 451f of the first suction sheet 451, between the first corner 451e and the second corner 451f. For example, the second attachment member 472 may be provided at the second corner 451f. Since the second attachment member 472 and the first attachment member 471 are spaced apart from each other, at least one air gap 460 may be located between the first attachment member 471 and the second attachment member 472. For example, the at least one air gap 460 may refer to a space between the first adsorption sheet 451 and the second adsorption sheet 452 that does not include the first attachment member 471 and the second attachment member 472.

[0113] As described above, since at least one air gap 460 is provided between the first adsorption sheet 451 and the second adsorption sheet 452, the electronic device (eg, Figure 4 The electronic device 200) may provide a resonance space (eg, Figure 4 The air in the resonance space 440) is connected to the plurality of adsorption sheets (eg, Figure 4 The contact area of ​​the plurality of adsorption sheets 450 can be expanded.

[0114] Figure 6a is a perspective view showing a plurality of exemplary adsorption sheets. Figure 6b is an exploded perspective view showing a plurality of exemplary adsorption sheets.

[0115] refer to Figure 6a and Figure 6b According to an embodiment, at least one attachment member 470 may include a third attachment member 473, a fourth attachment member 474, a fifth attachment member 475, a sixth attachment member 476, a seventh attachment member 477, and / or an eighth attachment member 478. Hereinafter, the third attachment member 473, the fourth attachment member 474, the fifth attachment member 475, the sixth attachment member 476, the seventh attachment member 477, and / or the eighth attachment member 478 are described as separate members, but this is for ease of description. For example, the third attachment member 473, the fourth attachment member 474, the fifth attachment member 475, the sixth attachment member 476, the seventh attachment member 477, and / or the eighth attachment member 478 may each represent a portion of at least one attachment member 470. For example, the third attachment member 473, the fourth attachment member 474, the fifth attachment member 475, the sixth attachment member 476, the seventh attachment member 477 and / or the eighth attachment member 478 can be referred to as the third part, the fourth part, the fifth part, the sixth part, the seventh part and / or the eighth part of at least one attachment member 470 formed integrally with each other.

[0116] According to an embodiment, the third attachment member 473 may extend along the first direction (eg, the −y direction). For example, the third attachment member 473 may extend along the first edge 451 a of the first adsorption sheet 451. For example, the third attachment member 473 may be substantially parallel to the first edge 451 a of the first adsorption sheet 451.

[0117] Depending on the embodiment, the fourth attachment member 474 may extend along the second direction (e.g., the +x direction). For example, the fourth attachment member 474 may extend from the third attachment member 473 along the second direction (e.g., the +x direction). For example, the fourth attachment member 474 may extend along the second edge 451b of the first suction sheet 451. For example, the fourth attachment member 474 may be substantially parallel to the second edge 451b of the first suction sheet 451.

[0118] Depending on the embodiment, the fifth attachment member 475 may extend in a third direction (e.g., the +y direction) opposite the first direction (e.g., the -y direction). For example, the fifth attachment member 475 may extend from the fourth attachment member 474 in the third direction (e.g., the +y direction). For example, the fifth attachment member 475 may extend along the third edge 451c of the first suction sheet 451. For example, the fifth attachment member 475 may be substantially parallel to the third edge 451c.

[0119] Depending on the embodiment, the sixth attachment member 476 may extend in a fourth direction (e.g., the −x direction) opposite the second direction (e.g., the +x direction). For example, the sixth attachment member 476 may extend from the fifth attachment member 475 in the fourth direction (e.g., the −x direction). For example, the sixth attachment member 476 may extend along the fourth edge 451 d of the first suction sheet 451. For example, the sixth attachment member 476 may be substantially parallel to the fourth edge 451 d. Depending on the embodiment, the sixth attachment member 476 may be spaced apart from the third attachment member 473. The sixth attachment member 476 may be disconnected from the third attachment member 473. For example, one end of the sixth attachment member 476 may be connected to the fifth attachment member 475, and the other end of the sixth attachment member 476, opposite the first end, may be spaced apart from the third attachment member 473.

[0120] Depending on the embodiment, the seventh attachment member 477 may extend in a first direction (e.g., the -y direction). For example, the seventh attachment member 477 may extend from the sixth attachment member 476 in the first direction (e.g., the -y direction). The seventh attachment member 477 may be spaced apart from the third attachment member 473, the fourth attachment member 474, and / or the fifth attachment member 475. For example, one end of the seventh attachment member 477 may be connected to the sixth attachment member 476. For example, the other end of the seventh attachment member 477, opposite the one end of the seventh attachment member 477, may be spaced apart from the third attachment member 473, the fourth attachment member 474, the fifth attachment member 475, and / or the sixth attachment member 476.

[0121] Depending on the embodiment, the eighth attachment member 478 may extend in the second direction (e.g., the +x direction). For example, the eighth attachment member 478 may extend from the seventh attachment member 477 in the second direction (e.g., the +x direction). The eighth attachment member 478 may be spaced apart from the third attachment member 473, the fourth attachment member 474, the fifth attachment member 475, and / or the sixth attachment member 476. For example, one end of the eighth attachment member 478 may be connected to the seventh attachment member 477. For example, the other end of the eighth attachment member 478, opposite the one end of the eighth attachment member 478, may be spaced apart from the third attachment member 473, the fourth attachment member 474, the fifth attachment member 475, the sixth attachment member 476, and / or the seventh attachment member 477.

[0122] According to an embodiment, at least one air gap 460 may be located between the third attachment member 473, the fourth attachment member 474, the fifth attachment member 475, the sixth attachment member 476, the seventh attachment member 477, and / or the eighth attachment member 478. For example, the at least one air gap 460 may be surrounded (or enclosed) by the third attachment member 473, the fourth attachment member 474, the fifth attachment member 475, the sixth attachment member 476, the seventh attachment member 477, and / or the eighth attachment member 478.

[0123] As described above, since at least one air gap 460 defined by at least one attachment member 470 is provided between the first adsorption sheet 451 and the second adsorption sheet 452, the electronic device according to the embodiment (eg, Figure 4 The electronic device 200) may provide a resonance space (eg, Figure 4 The air in the resonance space 440) is connected to the plurality of adsorption sheets (eg, Figure 4 The contact area of ​​the plurality of adsorption sheets 450 can be expanded.

[0124] At the same time, Figure 6b , the at least one attachment member 470 is shown extending in a clockwise direction relative to the center of the first adsorption sheet 451 on one surface of the first adsorption sheet 452 facing the second adsorption sheet 452, but the present invention is not limited thereto. For example, the at least one attachment member 470 may extend in a counterclockwise direction relative to the center of the first adsorption sheet 451 on one surface of the first adsorption sheet 451 facing the second adsorption sheet 452.

[0125] Figure 7a is a perspective view showing a plurality of exemplary adsorption sheets. Figure 7b is an exploded perspective view showing a plurality of exemplary adsorption sheets.

[0126] refer to Figure 7a and Figure 7bAccording to an embodiment, the plurality of adsorption sheets 450 may include at least one through-hole 455. Each of the first adsorption sheet 451 and the second adsorption sheet 452 may include at least one through-hole 455 that penetrates each of the first adsorption sheet 451 and the second adsorption sheet 452. For example, the number of the at least one through-hole 455 may correspond to the number of the plurality of adsorption sheets 450, but is not limited thereto. For example, the number of the at least one through-hole 455 may be greater than or less than the number of the plurality of adsorption sheets 450. According to an embodiment, the at least one through-hole 455 may penetrate at least a portion of each of the plurality of adsorption sheets 450. For example, the at least one through-hole 455 may penetrate the first adsorption sheet 451. For example, the at least one through-hole 455 may penetrate the second adsorption sheet 452. According to an embodiment, the at least one through-hole 455 may connect to at least one air gap 460 interposed between the plurality of adsorption sheets 450. For example, if the at least one through-hole 455 includes a plurality of through-holes, the at least one air gap 460 may be interposed between the plurality of through-holes. Since an empty space can be added inside the plurality of adsorption sheets 450 through at least one through hole 455, the plurality of adsorption sheets 450 and the resonance space (eg, Figure 4 The contact area between the resonance space 440) can be increased.

[0127] According to embodiments, at least one attachment member 470 may be provided along an edge of each of the plurality of adsorption sheets 450. For example, at least one attachment member 470 may be provided along edges 451a, 451b, 451c, and 451d of the first adsorption sheet 451. For example, the at least one attachment member 470 may have a closed loop form between the first adsorption sheet 451 and the second adsorption sheet 452. According to embodiments, the at least one attachment member 470 may surround at least one air gap 460 and at least one through-hole 455. For example, the at least one attachment member 470 may surround at least one air gap 460 between the first adsorption sheet 451 and the second adsorption sheet 452 and at least one through-hole 455 of the first adsorption sheet 451.

[0128] As described above, the electronic device according to the embodiment (eg, Figure 2 The electronic device 200) may provide a plurality of adsorption sheets 450 and a resonance space (eg, Figure 4 The contact area between the air in the resonance space 440 and the adsorption sheet 450 can be expanded by penetrating at least one through hole 455 of each of the plurality of adsorption sheets 450 .

[0129] Figure 8a is an exploded perspective view showing a plurality of exemplary adsorption sheets. Figure 8b is a diagram showing a plurality of exemplary adsorption sheets being arranged along Figure 8a A cross-sectional view of the example cut along line BB'.

[0130] refer to Figure 8a and Figure 8b According to embodiments, at least one attachment member 470 may be interposed between the first adsorption sheet 451 and the second adsorption sheet 452. According to embodiments, the at least one through-hole 455 may include a first through-hole 455a and a second through-hole 455b. The first through-hole 455a may penetrate the first adsorption sheet 451. For example, between the first corner 451e and the second corner 451f of the first adsorption sheet 451, the first through-hole 455a may be closer to the first corner 451e. The second through-hole 455b may penetrate the second adsorption sheet 452 disposed on the first adsorption sheet 451. According to embodiments, when the second adsorption sheet 452 is disposed above the first adsorption sheet 451 (e.g., in the -z direction) and viewed from above, the second through-hole 455b may be closer to the second corner 451f of the first adsorption sheet 451. According to an embodiment, the second suction sheet 452 may include a third corner 452e and a fourth corner 452f. The third corner 452e may correspond to the first corner 451e of the first suction sheet 451. For example, when the second suction sheet 452 is viewed from above (e.g., in the -z direction), the third corner 452e may overlap with the first corner 451e of the first suction sheet 451. The fourth corner 452f may be opposite to the third corner 452e. When the second suction sheet 452 is viewed from above (e.g., in the -z direction), the fourth corner 452f may overlap with the second corner 451f of the first suction sheet 451. Of the third corner 452e and the fourth corner 452f, the second through hole 455b may be closer to the fourth corner 452f.

[0131] According to an embodiment, the second through-hole 455b can be arranged to be staggered from the first through-hole 455a. The second through-hole 455b can be arranged so as not to overlap with the first through-hole 455a. When the second adsorption sheet 452 is viewed from above (e.g., in the -z direction) while the second adsorption sheet 452 is positioned above the first adsorption sheet 451 (e.g., in the -z direction), the second through-hole 455b can be positioned outside the first through-hole 455a. For example, when the second adsorption sheet 452 is viewed from above in a direction from the second adsorption sheet 452 toward the first adsorption sheet 451 (e.g., in the +z direction), the second through-hole 455b can be positioned outside the first through-hole 455a. For example, when the second adsorption sheet 452 is viewed from above in a direction from the second adsorption sheet 452 toward the first adsorption sheet 451 (e.g., in the +z direction), the second through-hole 455b can be spaced apart from the first through-hole 455a. For example, when the second adsorption sheet 452 is observed from above (e.g., in the -z direction) in a state where the second adsorption sheet 452 is arranged above the first adsorption sheet 451 (e.g., in the -z direction), the second through hole 455b can be closer to the second corner 451f between the first corner 451e and the second corner 451f of the first adsorption sheet 451.

[0132] According to an embodiment, at least one air gap 460 may be connected to at least one through hole 455 by being located between the first adsorption sheet 451 and the second adsorption sheet 452. For example, at least one air gap 460 may be connected to the first through hole 455a penetrating the first adsorption sheet 451 and the second through hole 455b penetrating the second adsorption sheet 452. Since at least one air gap 460 is connected to at least one through hole 455, the plurality of adsorption sheets 450 and the resonance space (e.g., Figure 4 The contact area between the air in the resonance space 440) can be increased.

[0133] As described above, the electronic device according to the embodiment (eg, Figure 4 The electronic device 200 may provide a structure in which a contact area between the plurality of adsorption sheets 450 and the air in the resonance space 440 may be expanded by at least one through hole 455 penetrating each of the plurality of adsorption sheets 450 .

[0134] Figure 9a is a perspective view showing a plurality of exemplary adsorption sheets. Figure 9b is an exploded perspective view showing a plurality of exemplary adsorption sheets.

[0135] refer to Figure 9a and Figure 9bAccording to embodiments, at least a portion of the plurality of adsorption sheets 450 may include a stepped structure. For example, the first adsorption sheet 451 may include a stepped portion 456. The stepped portion 456 may protrude from one surface 451g of the first adsorption sheet 451 facing the second adsorption sheet 452. For example, the stepped portion 456 may extend from one surface 451g of the first adsorption sheet 451 in the direction (e.g., the -z direction) that the one surface 451g of the first adsorption sheet 451 faces. For example, the distance between the stepped portion 456 and the second adsorption sheet 452 may be shorter than the distance between one surface 451g of the first adsorption sheet 451 (excluding the stepped portion 456) and the second adsorption sheet 452. According to embodiments, at least one attachment member 470 may be provided on the stepped portion 456.

[0136] According to an embodiment, at least one air gap 460 may be defined between the first adsorption sheet 451 and the second adsorption sheet 452 by the step portion 456 and the at least one attachment member 470. For example, the at least one air gap 460 may be surrounded by the step portion 456 and the at least one attachment member 470.

[0137] As described above, since at least one air gap 460 is formed between the plurality of adsorption sheets 450 by the step portion 456 and the at least one attachment member 470, the electronic device (eg, Figure 4 The electronic device 200) may provide a plurality of adsorption sheets 450 and a resonance space (eg, Figure 4 The contact area between the air in the resonance space 440) can be expanded.

[0138] Figure 10a is a perspective view showing a plurality of exemplary adsorption sheets. Figure 10b is an exploded perspective view showing a plurality of exemplary adsorption sheets.

[0139] refer to Figure 10a and Figure 10b According to an embodiment, each of the plurality of adsorption sheets 450 may include at least one receiving groove 457 formed by inwardly recessing a portion of each of the plurality of adsorption sheets 450. For example, the first adsorption sheet 451 may include at least one receiving groove 457 disposed (or formed) on one surface 451g of the first adsorption sheet 451 facing the second adsorption sheet 452. The receiving groove 457 may be formed by inwardly recessing one surface 451g of the first adsorption sheet 451.

[0140] According to an embodiment, at least one attachment member 470 may be accommodated in at least one receiving groove 457. At least one attachment member 470 may be disposed in at least one receiving groove 457. According to an embodiment, at least one attachment member 470 may contact the second suction sheet 452. For example, the thickness of at least one attachment member 470 may be thicker than the thickness of at least one receiving groove 457. Because the thickness of at least one attachment member 470 is thicker than the thickness of at least one receiving groove 457, a portion of at least one attachment member 470 may protrude outside of the at least one receiving groove 457. Because at least one attachment member 470 contacts the second attachment sheet 452 within the at least one receiving groove 457, one surface 451g of the first suction sheet 451, excluding the area where the at least one attachment member 470 is disposed, may be spaced apart from the second suction sheet 452. For example, one surface 451g of the first suction sheet 451, excluding the area where the at least one attachment member 470 is disposed, may be spaced apart from the second suction sheet 452 by a distance corresponding to the thickness of the at least one attachment member 470 protruding outside of the at least one receiving groove 457.

[0141] According to an embodiment, at least one air gap 460 may surround (or enclose) at least one attaching member 470 protruding from one surface 451 g of the first adsorption sheet 451 .

[0142] As described above, since at least one air gap 460 is formed between the plurality of adsorption sheets 450 by at least one attaching member 470 protruding outside the at least one receiving groove 457, the electronic device (eg, Figure 4 The electronic device 200) may provide a plurality of adsorption sheets 450 and a resonance space (eg, Figure 4 The contact area between the air in the resonance space 440) can be expanded.

[0143] Figure 11 is a perspective view showing a plurality of exemplary adsorption sheets.

[0144] refer to Figure 11 Depending on the embodiment, the plurality of adsorption sheets 450 may be arranged along the second direction (e.g., the +x direction) or the fourth direction (e.g., the -x direction). For example, the plurality of adsorption sheets 450 may be stacked along the second direction (e.g., the +x direction). For example, the plurality of adsorption sheets 450 may be stacked along the fourth direction (e.g., the -x direction). For example, the first adsorption sheet 451 and the second adsorption sheet 452 included in the plurality of adsorption sheets 450 may be stacked along the second direction (e.g., the +x direction).

[0145] According to an embodiment, the plurality of adsorption sheets 450 may be curved to have a curvature. The plurality of adsorption sheets 450 may have a coiled shape. For example, each of the plurality of adsorption sheets 450 may have a shape that rotates clockwise from the center of each of the plurality of adsorption sheets 450, but is not limited thereto.
