Description

Technical Field

[0001] Embodiments of this disclosure relate to an electronic device that forms a plurality of sound radiation channels corresponding to a loudspeaker and provides an audio signal optimized according to the movement of the plurality of sound radiation channels. Background Technology

[0002] Generally speaking, electronic devices include audio modules, such as speakers, for providing sound services to users, and the audio modules are fixed to the internal space of the electronic device.

[0003] One of the main uses of audio modules, such as speakers, is to provide sound services to users outside of electronic devices; therefore, sound radiation conduits are formed to radiate high-quality sound to the outside through the speakers.

[0004] As a related technology, when sound is radiated through a loudspeaker in an electronic device with a sound device, a single sound radiation channel fixed to a loudspeaker is formed to reflect the characteristics of the fixed radiation channel and provide good sound quality to the external user of the electronic device. Summary of the Invention

[0005] Technical issues

[0006] The existing technology only considers devices with a single speaker and a single sound radiation channel fixed in its corresponding position, and therefore may be difficult to apply to electronic devices with various shapes and shape-changing capabilities. For example, depending on the extent of display expansion, electronic devices with flexible or rollable displays may require one or more sound radiation channels for a single speaker, but the existing technology may not be sufficient to meet this requirement.

[0007] According to existing technology, simple changes in the sound radiation pipe may affect the characteristics of the audio signal passing through the corresponding pipe. Therefore, the sound quality may change continuously depending on the changes in the sound radiation pipe.

[0008] Based on current technology, it may not be possible to provide optimal sound quality to users of electronic devices with various shapes and changing shapes.

[0009] Solution to the problem

[0010] In an electronic device according to an embodiment of the present disclosure, the electronic device may include: a first housing and a second housing, the second housing being coupled to the first housing to be movable relative to the first housing; a speaker disposed in the first housing to output an audio signal; a flexible display having at least a portion disposed in the first and second housings, the flexible display having an area visually exposed to the front of the electronic device and whose size can expand according to the movement of the second housing; a first conduit formed in the first housing to allow the audio signal to be output to the outside of the first housing; a second conduit formed at a position corresponding to the first conduit when the movement distance of the second housing is within a first range, and formed in the second housing to allow the audio signal to pass through the first conduit and be output to the outside of the electronic device; a third conduit connected to the first conduit when the movement distance of the second housing is within a second range, and formed in the second housing to allow the audio signal to be output to the outside of the electronic device; and a processor operatively connected to the speaker and the flexible display, wherein the processor detects the movement distance of the second housing relative to the first housing and corrects the characteristics of the audio signal generated from the speaker based on the detected movement distance.

[0011] In an electronic device according to an embodiment of the present disclosure, the electronic device may include: a first housing and a second housing, the second housing being coupled to the first housing to be movable relative to the first housing; a speaker, included in the first housing to output an audio signal; a flexible display disposed in the first housing and the second housing and movable along the second housing; a first conduit formed in the first housing to allow the audio signal to be output to the outside of the second housing; a second conduit formed at a position corresponding to the first conduit when the flexible display is within a first range of movement distance relative to the first housing, and formed in the second housing to allow the audio signal to be output to the outside of the electronic device; and a processor operatively connected to the speaker and the flexible display, wherein the processor detects the movement distance of the flexible display relative to the first housing and corrects the characteristics of the audio signal generated from the speaker based on the conduit state according to the detected movement distance.

[0012] Beneficial effects of the invention

[0013] According to various embodiments of the present invention, as the shape of the electronic device changes, the shape of the sound radiation conduit of the audio module, such as a speaker, can also change, thus providing the user with optimal sound service through a structure that adapts to shape changes.

[0014] According to various embodiments of the present invention, by pre-storing audio characteristics corresponding to the shape of the sound radiation pipe according to the shape of the electronic device to be changed, and by pre-applying supplementary audio signal characteristics, the same quality audio output can be provided to the user even when the sound radiation pipe is changed.

[0015] According to various embodiments of this disclosure, abrupt changes in sound quality can be reduced by gradually supplementing the characteristics of the audio signal.

[0016] The effects that can be obtained based on various embodiments are not limited to those mentioned above, and those skilled in the art to which this disclosure pertains will clearly understand from the following description other effects not mentioned herein. Attached Figure Description

Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth™, 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, 5G network, 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 can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify or verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

According to an embodiment, all or some operations that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, 104, or 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, the one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used.

In an embodiment, the display 320 may be as follows: Figure 2-1 The display 320 is shown in a state where it is not moved (or extended). In this embodiment, the display 320 can be as follows: Figure 2-2 The diagram shows the movement (or extension) of d1 based on a non-moving state (or non-extended state). Furthermore, the display 320 can be as follows: Figure 2-3 The diagram shows the movement (or expansion) of d2 based on the non-moving state (or non-expanding state).

[0071] According to the embodiment, d2 can be the maximum moving distance of the display 320, and d1 can be any distance before the maximum moving distance of the display 320.

[0072] According to an embodiment, the display 320 can move a distance equal to d1 or d2 based on a non-moving state (or a non-extended state). In this way, when the extended distance of the display 320 increases, the situation can be described as sliding out.

[0073] According to an embodiment, the display 320 can change from a state of movement equal to d1 or d2 to a non-moving state (or non-extended state), in which case the situation can be described as sliding in when the extension distance of the display 320 decreases.

[0080] According to an embodiment, the memory 350 may store information about the movement (or extension) distance and movement status of the display 320.

[0081] According to an embodiment, the processor 240 can identify the movement (or extension) distance and pipeline status corresponding to the movement state of the display 320.

[0082] According to an embodiment, the electronic device 201 may further include a display movement detection sensor 330.

[0083] In this embodiment, the display motion detection sensor 330 can detect the movement of the display 320. For example, the display motion detection sensor 330 can detect the movement (or extension) distance and movement state of the display 320. As another example, when detecting the movement of the display 320, the display motion detection sensor 330 can be based on magnets and Hall sensors, wires and resistance sensing, optical sensors, or capacitance.

[0084] In this embodiment, the display motion detection sensor 330 can detect the movement of the second housing 220. For example, under the control of the processor 310, the electronic device 201 can detect the movement (or extension) distance and movement state of the second housing 220 relative to the first housing and the display 320.

[0085] In one embodiment, the processor 310 may be operatively coupled to the display motion detection sensor 330 and control the operations performed by the display motion detection sensor 330.

[0086] Figure 4-1 to Figure 4-3This is a view illustrating how the display of the electronic device, including a speaker, in the embodiment moves (or expands). Figure 4-1 to Figure 4-3 middle, Figure 4-1 to Figure 4-3 The diagram shows a gradual change based on the extent of the display's expansion.

[0087] In an embodiment, Figure 4-1 This shows the state where the display 320 has not moved (or extended). Furthermore, Figure 4-1 The second housing 220 is shown in a state where it has not moved (or expanded) relative to the first housing 210.

[0088] In the embodiments, reference is made to Figure 4-1 The electronic device 201 may include a first housing 210 and a second housing 220 coupled to the first housing 210 and movable relative to the first housing 210. In an embodiment, the first housing 210 of the electronic device 201 may be a fixed housing. For example, when the display 320 moves or expands, at least a portion of the second housing 220 may move with the display 320, while the first housing 210 may be fixed and not move.

[0089] In an embodiment, a conduit (e.g., a first conduit 211) may be formed in the first housing 210 to output (or radiate) audio signals (or sound) generated from a speaker (e.g., speaker 340) in the electronic device 201 to the outside of the first housing 210. For example, the first conduit 211 may be a conduit through which the audio signal generated from the speaker 340 is output to the outside of the first housing 210. The first conduit 211 may be described as a conduit for radiating sound from the speaker 340.

[0090] In one embodiment, the first conduit 211 may be formed on one side of the first housing 210. For example, the first conduit 211 may be as follows: Figure 4-3 It is shown to be formed on one side of the first housing 210 and on the lower side of the first housing 210.

[0091] In an embodiment, a second conduit 221 may be formed within the second housing 220 to output audio signals (or sound) generated from a speaker (e.g., speaker 340) to the outside of the second housing 220. For example, in a display 320... Figure 4-1 In the unextended state shown, the audio signal or sound generated from the speaker 340 can be output to the outside of the first housing 210 through the first conduit 211, and output to the outside of the second housing 220 through the second conduit 221.

[0092] In an embodiment, when the display 320 is not moved, the second conduit 221 may be formed at a position corresponding to the first conduit 211 (e.g., the position of the second housing 220 corresponding to the first conduit 211). For example, when the display 320 is not moved, the second conduit 221 may be formed at a position where the cross-section of the second conduit 221 and the cross-section of the first conduit 211 at least partially overlap each other. As another example, Figure 4-1 The position of the second pipe 221 in the middle can correspond to Figure 4-3 The location of the first pipeline 211.

[0093] In an embodiment, even in the display 320, such as Figure 4-2 In the state where the display 320 has moved a predetermined distance, the cross-sections of the second conduit 221 and the first conduit 211 may at least partially overlap each other, depending on the distance moved. In an embodiment, when the display 320 has moved a predetermined distance or more, the cross-sections of the second conduit 221 and the first conduit 211 may not overlap each other in at least a portion of their cross-sections.

[0094] In an embodiment, Figure 4-1 to Figure 4-3 The external structure of the electronic device 201 is shown, but internal conduits (e.g., a third conduit 222) may be formed inside the electronic device 201 to output audio signals from the speaker 340 to the outside. For example, the third conduit 222, distinct from the first conduit 211 and the second conduit 221, may be formed inside the second housing 220, and the third conduit 222 may be a radiating conduit for outputting audio signals or sound from the speaker 340 to the outside of the second housing 220.

[0095] In this embodiment, when the display 320 is not extended, the audio signal output from the speaker 340 can pass through the first conduit 211 and the second conduit 221 and be output (or radiated) to the outside of the electronic device 201. For example, the audio signal or sound from the speaker 340 can be output to the outside of the first housing 210 through the first conduit 211, and the output audio signal or sound can be output to the outside of the second housing 220 through the second conduit 221.

[0096] In this embodiment, even when the display 320 is extended, the audio signal output from the speaker 340 can pass through the first conduit 211 and the second conduit 221 and be output (or radiated) to the outside of the electronic device 201. For example, the audio signal or sound from the speaker 340 can be output to the outside of the first housing 210 through the first conduit 211, and at least a portion of the audio signal or sound output to the outside of the first housing 210 can pass through the second conduit 221 and be output to the outside of the second housing 220.

[0097] In this embodiment, when the display 320 is extended by a predetermined distance or more, the audio signal output from the speaker 340 can pass through the first conduit 211 and the third conduit 222 and be output (or radiated) to the outside of the second housing 220 (or the electronic device 201). For example, the audio signal or sound from the speaker 340 can be output to the outside of the first housing 210 through the first conduit 211, and the output audio signal or sound can be output to the outside of the second housing 220 through the third conduit 222.

[0098] Figure 5-1 to Figure 5-2 The diagram illustrates the structure of the electronic device, including a speaker, in an embodiment where the display is not moved. Specifically, Figure 5-1 to Figure 5-2 Perspective and sectional views of the electronic device, including the speaker, are shown.

[0099] For ease of explanation, Figure 5-1 to Figure 5-2 The first housing 210 and the second housing 220 are shown in their separated state before connection. Furthermore, this cross-sectional view is a perspective view of the electronic device 201 cut along A-A'.

[0100] In an embodiment, the electronic device 201 may include a first housing 210 and a second housing 220, the second housing 220 being coupled to the first housing 210 to be movable or expandable relative to the first housing 210.

[0101] In one embodiment, the speaker 340 may be included in the first housing 210, and the first conduit 211 may be formed within the first housing 210. For example, the speaker 340 may be disposed in the lower part of the first housing 210 for smooth output of audio signals or sound, but is not limited thereto. As another example, the first conduit 211 may be formed in the inner housing on the lower side of the first housing 210, but is not limited thereto.

[0102] In one embodiment, the first conduit 211 may be formed in the first housing 210 at a position corresponding to the location where the speaker 340 is disposed. For example, the speaker 340 may be disposed in the lower part of the first housing 210, and the first conduit 211 may be formed in the first housing 210 corresponding to the location where the speaker 340 is disposed.

[0103] In an embodiment, a second conduit 221, distinct from the first conduit 211, may be formed in the second housing 220. For example, the second conduit 221 may be formed on the underside of the second housing 220 at the location where the first conduit 211 forms the first housing 210. Furthermore, the second conduit 221 may be formed in a shape that extends through at least a portion of the underside of the second housing 220.

[0104] In an embodiment, a third conduit 222, distinct from the first conduit 211 and the second conduit 221, may be formed in the second housing 220. For example, the third conduit 222 may be formed on the underside of the second housing 220. As another example, the third conduit 222 may be formed to be spaced apart from the second conduit 221 by a predetermined distance. The third conduit 222 may have the shape of a linear hole formed along the underside of the second housing 220.

[0105] In this embodiment, the first conduit 211, the second conduit 221, and the third conduit 222 may be formed in the shape of holes to output audio signals or sound. For example, the first conduit 211 may have the shape of multiple holes extending through at least a portion of the lower side of the first housing 210, and the second conduit 221 and the third conduit 222 may be formed in the shape of multiple holes extending through at least a portion of the lower side of the second housing 220. As another example, the first conduit 211, the second conduit 221, and the third conduit 222 may also be formed in the shape of a single hole.

[0109] Figure 7 The structure shown in the embodiment is viewed in direction ① when the display of the electronic device including the speaker is not moved.

[0110] In the embodiments, reference is made to Figure 7The speaker 340 may be disposed at the lower part of the electronic device 201 (or the first housing 210). In an embodiment, the first conduit 211 may be formed on the lower side of the first housing 210 corresponding to the location where the speaker 340 is disposed. In an embodiment, the second conduit 221 may be formed in the second housing 220 at a position corresponding to the location where the first conduit 211 is formed. In an embodiment, the first conduit 211 and the second conduit 221 may be in the shape of multiple holes. In an embodiment, the third conduit 222 may be formed at a position spaced at a predetermined distance from the location where the second conduit 221 is formed. In an embodiment, the third conduit 222 may be formed along the lower side of the second housing 220 and may be in the shape of multiple holes or even in the shape of a single hole. In an embodiment, the third conduit 222 may have the shape of a through hole that can be connected to the outside of the second housing 220.

[0111] Figure 8 The structure shown in the embodiment is viewed in direction ② when the display of the electronic device including the speaker is not moved.

[0112] In one embodiment, a speaker 340 may be disposed in a first housing 210, and a first conduit 211 may be formed in the first housing 210 corresponding to the position of the speaker 340. The first conduit 211 may be formed in the first housing 210, and audio signals or sounds generated from the speaker 340 may be output to the outside of the second housing 220 through the first conduit 211 and another conduit (e.g., a second conduit 221 and a third conduit 222).

[0113] In one embodiment, the second conduit 221 of the second housing 220 may be formed at a position corresponding to the first conduit 211. In another embodiment, the second conduit 221 may be formed at a position corresponding to the first conduit 211, thereby outputting the audio signal or sound from the speaker 340 output through the first conduit 211 to the outside of the second housing 220. In another embodiment, the second conduit 221 may have the shape of a hole extending through at least a portion of the lower side of the second housing 220. In another embodiment, when the display 320 is not extended, the second conduit 221 may be formed at a position corresponding to the first conduit 211; therefore, the second conduit can output the audio signal or sound from the speaker 340 output through the first conduit 221 to the outside of the second housing 220.

[0114] In one embodiment, the third conduit 222 may have the shape of a hole formed along the lower side of the second housing 220. In another embodiment, the third conduit 222 may have the shape of multiple holes, but is not limited thereto. In yet another embodiment, the third conduit 222 may have the shape of a hole that can be connected to the outside of the second housing 220.

[0115] Figure 9The structure shown in the embodiment is viewed in direction ③ when the display of the electronic device including the speaker is not moved.

[0116] In one embodiment, since the second conduit 221 is formed in the second housing 220, a plurality of holes can be formed. In another embodiment, the second conduit 221 can be formed in the shape of extending through a plurality of holes in the second housing 220.

[0117] In an embodiment, although not visible from the outside of the second housing 220, the third conduit 222 may be formed as a hole along the inside of the second housing 220. In an embodiment, the third conduit 222 may be formed as a plurality of holes or as a single hole. In an embodiment, the third conduit 222 may be connected to the outside of the second housing 220.

[0118] Figure 10 The illustration shows a process in which an electronic device including a speaker corrects the characteristics of an audio signal based on the movement of a display.

[0119] Reference Figure 11-1 to Figure 11-3 Description based on Figure 10 The operating procedure of electronic device 201 Figure 11-1 to Figure 11-3 An embodiment is shown that describes the characteristics of an audio signal based on the state of a conduit in which an electronic device in which a display moves.

[0120] According to an embodiment, in operation 1010, the electronic device 201 can detect the movement distance of the flexible display.

[0121] In this embodiment, the display 320 may be a flexible display or a rollable display. For example, the display 320 may be a flexible display or a rollable display that can be bent by external pressure.

[0122] In this embodiment, the electronic device 201 can detect the movement of the display 320 under the control of the processor 310. For example, when the display 320 is moved by the user or when the display 320 itself moves, the electronic device 201 can detect the movement of the display 320 based on the control of the processor 310.

[0123] In an embodiment, the processor 310 of the electronic device 201 can detect movement of the display 320 based on the display motion detection sensor 330. For example, the electronic device 201 may include the display motion detection sensor 330 for detecting movement of the display 320. The electronic device 201 can detect the movement (e.g., movement distance) of the display 320 by using the display motion detection sensor 330 under the control of the processor 310.

[0124] In the embodiments, reference is made to Figure 11-1 to Figure 11-3 The electronic device 201 can, under the control of the processor 310, according to, such as Figure 11-1 to Figure 11-3 The movement of the display 320 or the second housing 220 is detected. For example, the movement distance of the second housing 220 relative to the first housing 210 can be... Figure 11-2 China and Belgium in Figure 11-1 The second housing 220 can move a greater distance relative to the first housing 210. Figure 11-3 China and Belgium in Figure 11-2 The middle is larger. As another example, Figure 11-2 The movement distance (or extension range) of the monitor 320 in the middle can be greater than Figure 11-1 The distance (or extent) of movement of the display 320 in the middle, and Figure 11-3 The movement distance (or extension range) of the display 320 in the middle can be greater than Figure 11-2 The distance (or extent) of movement of the display 320. The electronic device 201 can detect the distance of movement or extent of extension of the display 320 by means of the processor 310 or by means of the display movement detection sensor 330 under the control of the processor 310.

[0125] In one embodiment, the electronic device 201 can identify the piping status based on the detected movement distance. In another embodiment, the electronic device 201 can detect the movement distance (or extent of expansion) of the display 320 under the control of the processor 310, and identify the piping status based on the detected movement distance (or extent of expansion). For example, refer to... Figure 11-1 to Figure 11-3 Electronic device 201 can detect, for example Figure 11-1 to Figure 11-3 The display 320 shows the movement distance (or extent of expansion) and identifies the piping status (e.g., first state, second state, third state) based on the detected movement distance (or extent of expansion). See reference... Figure 11-1 The first conduit 211 of the electronic device 201 can be connected to the second conduit 221. For example, the first conduit 211 can be fully or partially connected to the second conduit 221, and thus can be connected to the outside of the second housing 220. As another example, audio signals or sounds generated from the speaker 340 can pass through the first conduit 211 and the second conduit 221 and be output (or radiated) to the outside of the second housing 220. In this case, the conduit state of the electronic device 201 can be defined as a first state, and the electronic device 201 can identify the conduit state of the first state under the control of the processor 310. (Refer to...) Figure 11-2The first conduit 211 of the electronic device 201 can be connected to the third conduit 222. For example, the first conduit 211 can be connected to the third conduit 222, thus connecting to the outside of the second housing 220. As another example, an audio signal or sound generated from the speaker 340 can pass through the first conduit 211 and the third conduit 222 and be output (or radiated) to the outside of the second housing 220. In this case, the conduit state of the electronic device 201 can be defined as a second state, and the electronic device 201 can identify the conduit state of the second state under the control of the processor 310. (Refer to...) Figure 11-3 The first conduit 211 of the electronic device 201 can be connected to the outside of the second housing 220 without being connected to the second conduit 221 or the third conduit 222. For example, the first conduit 211 can be connected to the outside of the second housing 220, so that the output (or radiation) is directed to the outside of the second housing 220, while the audio signal or sound generated from the speaker 340 does not pass through the second conduit 221 and / or the third conduit 222. In this case, the conduit state of the electronic device 201 can be defined as a third state, and the electronic device 201 can identify the conduit state of the third state under the control of the processor 310.

[0126] In an embodiment, the piping state can be a first state when the movement distance of the display (e.g., display 320) relative to the first housing 210 is within a predetermined range (e.g., a first range). For example, the first range can be the range of distances from which the display 320 moves to where the first piping 211 and the second piping 221 end overlapping each other.

[0127] In an embodiment, the piping state can be a second state when the movement distance of the display (e.g., display 320) relative to the first housing 210 is within a predetermined range (e.g., a second range). For example, the second range can be the range of distances from which the display 320 moves to where the first piping 211 begins to overlap with the third piping 222 while the first piping 211 and the second piping 221 do not overlap with each other.

[0128] In an embodiment, the piping state can be a first state when the movement distance of the display (e.g., display 320) relative to the first housing 210 is within a predetermined range (e.g., a first range). For example, the first range can be the range of distances from which the display 320 moves to where the first piping 211 and the second piping 221 end overlapping each other.

[0129] In an embodiment, the piping state can be a second state when the movement distance of the display (e.g., display 320) relative to the first housing 210 is within a predetermined range (e.g., a second range). For example, the second range can be the range of distances from which the display 320 moves to where the first piping 211 begins to overlap with the third piping 222 while the first piping 211 and the second piping 221 do not overlap with each other.

[0130] In an embodiment, the piping state can be a third state when the movement distance of the display (e.g., display 320) relative to the first housing 210 is within a predetermined range (e.g., a third range). For example, the third range can be the range of distances from which the display 320 moves to a point where the first piping 211 does not overlap with the third piping 222 and the first piping 211 and the second piping 221 do not overlap with each other.

[0131] In an embodiment, the third range may be a range in which the display 320 moves a greater distance relative to the first housing 210 compared to the first range and the second range.

[0132] In an embodiment, the second range may be a range in which the display 320 moves a greater distance relative to the first housing 210 compared to the first range.

[0133] According to an embodiment, in operation 1020, electronic device 201 can correct the characteristics of the audio signal generated from a speaker (e.g., speaker 340) based on the detected movement distance of the flexible display (e.g., display 320).

[0134] In this embodiment, the electronic device 201, under the control of the processor 310, can identify which range the detected movement distance belongs to. For example, the electronic device 201, under the control of the processor 310, can identify which of the aforementioned first, second, and third ranges the detected movement distance belongs to.

[0135] In an embodiment, the electronic device 201 may pre-store the characteristics of the audio signal according to the identified range (e.g., a first range, a second range, and a third range) in the memory 350.

[0136] In this embodiment, the electronic device 201, under the control of the processor 310, can identify filters corresponding to the characteristics of an audio signal, such as a frequency response curve, based on a first to a third range. Furthermore, the processor 310 can use the identified filters to correct the characteristics of the audio signal, thus allowing the electronic device 201 to output the corrected audio signal to an external location.

[0137] According to another embodiment, under the control of the processor 310, the electronic device 201 can correct the characteristics of the audio signal generated from the speaker based on the identified pipeline state.

[0138] In an embodiment, electronic device 201 may pre-store the characteristics of audio signals based on identified pipeline states (e.g., first state, second state, and third state) in memory 350. For example, electronic device 201 may store, for instance, the characteristics of audio signals based on identified pipeline states (e.g., first state, second state, and third state) in memory 350. Figure 11-1The pipeline status shown is identified as the first state, and will be such as with Figure 11-1 The characteristics of the audio signal corresponding to the curve (e.g., the frequency response curve according to the first state) are stored in memory 350. As another example, electronic device 201 can store the characteristics of the audio signal as follows: Figure 11-2 The pipeline status shown is identified as the second state, and will be such as with Figure 11-2 The characteristics of the audio signal, corresponding to a graph (e.g., a frequency response graph based on the second state), are stored in memory 350. Furthermore, electronic device 201 can store, for example, the characteristics of the audio signal as shown in the graph. Figure 11-3 The pipeline status shown is identified as the third state, and will be such as with Figure 11-3 The characteristics of the audio signal corresponding to the curve (e.g., the frequency characteristic curve of the third state) are stored in the memory 350.

[0139] In an embodiment, electronic device 201 can apply a filter based on the characteristics of the audio signal pre-stored in memory 350, thereby correcting the characteristics of the audio signal. For example, electronic device 201 can identify characteristics of the audio signal (such as frequency response curves based on first to third states, or characteristics pre-stored in memory 350) and... Figure 11-1 to Figure 11-3 The corresponding curve (corresponding filter). Furthermore, the electronic device 201 can use the identified filter to correct the characteristics of the audio signal, thereby outputting the corrected audio signal to the outside of the electronic device 201.

[0140] In this embodiment, due to the structural characteristics of the electronic device 201, the audio signal or sound in the third state is minimally affected by the output (or radiation) of the audio signal or sound generated from the speaker 340. In this embodiment, due to the structural characteristics of the electronic device 201, the audio signal or sound in the first and second states is more susceptible to volume reduction, partial frequency loss, and per-band frequency loss compared to the third state.

[0141] Figure 12 The illustration shows a process in which an electronic device including a speaker uses a filter to correct the characteristics of an audio signal corresponding to the pipeline state.

[0142] Reference Figure 13 and Figure 14 Conduct the investigation Figure 12 A description of the operating procedures performed by the electronic device 201 in the document. Figure 13 The characteristics of first and second correction filters used to correct the characteristics of audio signals corresponding to pipeline conditions are shown. Figure 14 The characteristics of a third correction filter are shown, which corrects the audio signal corresponding to the pipeline state differently according to case 1 and case 2.

[0143] According to an embodiment, in operation 1210, an audio signal can be generated from the speaker 340 of the electronic device 201.

[0144] In one embodiment, the electronic device 201 may include a speaker 340, and audio signals or sounds may be generated from the speaker 340. In another embodiment, conduits may be formed for outputting (or radiating) the audio signals or sounds generated from the speaker 340 to the exterior of the electronic device 201 or to the exterior of the second housing 220 in which the speaker 340 is located. In yet another embodiment, the audio signals or sounds from the speaker 340 may be output to the exterior through conduits formed in the housings of the electronic device 201 (e.g., the first housing 210 and the second housing 220).

[0145] According to an embodiment, in operation 1220, the electronic device 201 can identify a filter used to correct the characteristics of an audio signal corresponding to the pipeline state.

[0146] In an embodiment, the electronic device 201 can, under the control of the processor 310, identify the movement distance (e.g., a first to a third range) and / or pipeline state (e.g., a first to a third state) of the display (e.g., the first to a third range) and / or pipeline state, and each of the movement distance (e.g., the first to a third range) and / or pipeline state can have audio characteristics corresponding to the structural characteristics of the electronic device 201. For example, referring to... Figure 11-1 to Figure 11-3 When compared to the graph corresponding to the third state, the graph corresponding to the first state may include audio characteristics with reduced volume and partial frequency loss. As another example, when compared to the graph corresponding to the third state, the graph corresponding to the second state may include audio characteristics with frequency loss in both the low-frequency and high-frequency bands.

[0147] In an embodiment, electronic device 201 may, under the control of processor 310, store audio characteristics corresponding to travel distance (e.g., the first to third range) and / or pipeline state (e.g., the first to third state). For example, under the control of processor 310, electronic device 201 may pre-store audio characteristics such as volume characteristics, frequency characteristics, and frequency characteristics for each frequency band in memory 350 for the first to third states (or the first to third range).

[0148] In an embodiment, the electronic device 201 can identify a correction filter corresponding to a travel distance (e.g., a first to a third range) and / or a pipeline state (e.g., a first to a third state) under the control of the processor 310.

[0149] In the embodiments, reference is made to Figure 13The electronic device 201, under the control of the processor 310, can identify a first correction filter for correcting the volume reduction and partial frequency loss in the first state relative to the third state. The first correction filter may be a filter that includes audio characteristics that correct for the differences in volume reduction and partial frequency loss compared to the audio characteristics of the third state.

[0150] In the embodiments, reference is made to Figure 13 The electronic device 201, under the control of the processor 310, can identify a second correction filter for correcting frequency losses in the low and high frequency bands in the second state relative to the third state. The second correction filter may be a filter that includes audio characteristics that correct for frequency differences in each frequency band for which losses have occurred, compared to the audio characteristics of the third state.

[0151] In an embodiment, electronic device 201, under the control of processor 310, can identify a third correction filter for correcting the characteristics of an audio signal in a third state, the characteristics of which serve as a reference for correcting the differences in audio characteristics between the first and second correction filters. The third correction filter can apply different audio characteristics depending on the volume of the audio. For example, when the volume of the audio generated from speaker 340 is low, sufficient correction is performed only by the first and second correction filters; therefore, electronic device 201, under the control of processor 310, can identify a third correction filter that does not affect the audio characteristics. As another example, when the volume of the audio generated from speaker 340 is high, the electronic device can identify a third correction filter that can perform volume reduction and / or frequency level reduction.

[0152] According to an embodiment, in operation 1230, electronic device 201 can use the identified filter to correct the characteristics of the audio signal generated from the speaker.

[0153] In an embodiment, when the pipeline state identified under the control of the processor 310 is in a first state, the electronic device 201 can apply a first correction filter to correct the characteristics of the audio. For example, the electronic device 201 can apply the first correction filter under the control of the processor 310 to correct characteristics that need correction compared to the characteristics of the audio in the third state (e.g., volume reduction, partial frequency level loss).

[0154] In an embodiment, when the pipeline state identified under the control of processor 310 is in the second state, electronic device 201 can apply a second correction filter to correct the characteristics of the audio. For example, electronic device 201 can apply the second correction filter under the control of processor 310 to correct characteristics that need correction compared to the characteristics of the audio in the third state (e.g., frequency level loss for each frequency band).

[0155] In an embodiment, when the pipeline state identified under the control of the processor 310 is in the third state, the electronic device 201 can apply a third correction filter to correct the audio characteristics. For example, under the control of the processor 310, the electronic device 201 can apply the third correction filter to both low and high audio volume conditions to correct the audio characteristics when the volume is too high.

[0156] According to an embodiment, in operation 1240, the electronic device 201 can output an audio signal to the outside.

[0157] In one embodiment, the electronic device 201 may apply first to third correction filters under the control of the processor 310. In another embodiment, the electronic device 201 may apply correction filters (e.g., a first correction filter, a second correction filter, and a third correction filter) under the control of the processor 310, thereby outputting (or radiating) an audio signal with corrected audio characteristics to the outside of the electronic device 201.

[0158] In various embodiments, the above description of the first to third states may be applied when the movement distance of the display (e.g., display 320) is within the first to third range.

[0159] Figure 15-1 to Figure 15-2 The characteristics of the audio signal corrected by using a correction filter corresponding to the pipeline state are shown in the embodiment.

[0160] In various embodiments, according to Figure 15-1 to Figure 15-2 The description of the pipeline state (e.g., first to third states) can be applied to cases where the movement distance of the display (e.g., display 320) is within the first to third range.

[0161] In an embodiment, Figure 15-1 The differences in audio characteristics between the first and third states before applying correction filters (e.g., first to third correction filters) are shown. (Refer to...) Figure 15-1 Due to reduced volume, frequency loss, and frequency level loss for each frequency band, the audio characteristics corresponding to the first and second states differ from those in the third state, which serves as the correction reference.

[0162] In an embodiment, Figure 15-2 The differences in audio characteristics between the first and third states after applying correction filters (e.g., first to third correction filters) are shown. (Refer to...) Figure 15-2Compared with the audio characteristics in the third state, which serves as the correction reference, it can be identified that the difference between the audio characteristics corresponding to the first and second states, where the correction filter has been applied, is significantly reduced.

[0163] In the embodiments, reference is made to Figure 15-1 to Figure 15-2 The electronic device 201 can apply a correction filter corresponding to the pipeline state under the control of the processor 310, thereby obtaining the same or similar audio characteristics in the first to third states.

[0164] Figure 16 The embodiment illustrates the operation of interpolating the characteristics of an audio signal corresponding to a pipeline state using multiple filters.

[0165] In various embodiments, according to Figure 16 The description of the pipeline state (e.g., first to third states) can be applied to cases where the movement distance of the display (e.g., display 320) is respectively within the first to third ranges.

[0166] In an embodiment, the electronic device 201 may interpolate and apply first to third correction filters at each extension step of the display 320, thereby reducing rapid changes in audio characteristics (e.g., sound quality) from the speaker 340 to the outside of the electronic device 201.

[0167] In one embodiment, by extending the display 320 from its previous state before the display 320 of the electronic device 201 by a predetermined distance, the conduit state can be changed from a first state to a second state. Furthermore, by extending the display 320 from its previous state after the predetermined distance of extension of the electronic device 201 by a predetermined distance or more, the conduit state can be changed from a second state to a third state.

[0168] In an embodiment, the electronic device 201 in the first state can apply a first correction filter under the control of the processor 310, and the electronic device 201 in the second state can apply a second correction filter under the control of the processor 310. In an embodiment, when the pipeline state of the electronic device 201 changes from the first state to the second state according to the expansion of the display 320, the rapid change of audio characteristics can be reduced by applying a fourth correction filter that interpolates the median between the audio characteristics of the first correction filter and the audio characteristics of the second correction filter during the time delay period and has a predetermined time delay before and after the change.

[0169] In an embodiment, the electronic device 201 in the second state can apply a second correction filter under the control of the processor 310, and the electronic device 201 in the third state can apply a third correction filter under the control of the processor 310. In an embodiment, when the pipeline state of the electronic device 201 changes from the second state to the third state according to the expansion of the display 320, the rapid change of audio characteristics can be reduced by applying a fifth correction filter that interpolates the median between the audio characteristics of the second correction filter and the audio characteristics of the third correction filter during the time delay period and has a predetermined time delay before and after the change.

[0170] Figure 17 An example is shown in which the characteristics of the audio signal corresponding to the pipeline state are corrected.

[0171] In various embodiments, according to Figure 17 The description of the pipeline state (e.g., first to third states) can be applied to cases where the movement distance of the display (e.g., display 320) is respectively within the first to third ranges.

[0172] In an embodiment, during the stage when the volume generated from the speaker 340 is at its highest, the structural difference between the third state and the second state of the electronic device 201 can be large, so the effect of the correction filter in compensating for the audio characteristics can appear relatively low.

[0173] In an embodiment, during a phase where the volume is lower than the highest volume generated by speaker 340, when the state of the conduit through which the audio output from speaker 340 changes, the audio output of the reference third state can be reduced, and the difference in audio characteristics between the first and second states and the third state, and thus the effect of applying a correction filter, can be further increased. For example, the output characteristics of the final audio signal for each state of the conduit through which the audio signal from the output electronics 201 is transmitted can be similar to each other. As a specific example, when the highest volume level is level 15, if the conduit state changes from the third state to the second state while the speaker 340 is played at volume level 14, the virtual volume level can be maintained at level 15, and a correction filter can be applied.

[0174] Figure 18-1 to Figure 18-3 The shape of the display movement (expansion) of the electronic device including the speaker in the embodiment is shown.

[0175] In various embodiments, according to Figure 18 The description of the pipeline state (e.g., first to third states) can be applied to cases where the movement distance of the display (e.g., display 320) is respectively within the first to third ranges.

[0176] In an embodiment, electronic device 201 may include a first housing 410, a second housing 420, and a speaker 340.

[0177] In an embodiment, the second housing 420 may be coupled to the first housing 410 so that it is movable relative to the fixed first housing 410. For example, the second housing 420 may move as the display (e.g., display 320) moves or expands, and the distance of the second housing 420 relative to the first housing 410 may change.

[0178] In an embodiment, the first housing 410 may include a speaker 340. For example, the speaker 340 may be disposed inside the first housing 410, and the speaker 340 may be disposed at the lower part of the first housing in which a conduit (e.g., conduit 411) is formed for the smooth output of the generated audio signal or sound.

[0179] In the embodiments, reference is made to Figure 18-1 to Figure 18-3 The conduit 411 can be formed in the first housing 410 at a location corresponding to the speaker 340. For example, the conduit 411 can be formed in the first housing as a plurality of holes or a single hole. Furthermore, in order to ensure a smooth output of audio signals or sound generated from the speaker 340, the conduit 411 can be formed at a location corresponding to the speaker 340. As another example, the conduit 411 can be formed to extend through at least a portion of the first housing 410.

[0180] In the embodiments, reference is made to Figure 18-1 When the display (e.g., display 320) is not moved or extended (e.g., in the first state), conduit 421 can be formed at a position corresponding to conduit 411. For example, conduit 421 can be formed in the second housing 420 and formed to extend through at least a portion of the second housing 420. As another example, audio signals or sounds generated from speaker 340 can be output to the outside of the first housing 410 via conduit 411 and to the outside of the second housing 420 via conduit 421.

[0181] In the embodiments, reference is made to Figure 18-2 In a state where the display (e.g., display 320) moves or extends a predetermined distance (e.g., a second state), conduits 411 and 421 can be positioned to partially correspond to each other. For example, the cross-sections of conduits 411 and 421 can at least partially overlap each other. Alternatively, conduits 411 and 421 can be described as sharing a portion of each other. As another example, audio signals or sounds generated from the speaker 340 can pass through conduit 411 and be output to the outside of the second housing 420 through at least a portion of conduit 421.

[0182] In the embodiments, reference is made to Figure 18-3 In a state where the display (e.g., display 320) moves or extends a predetermined distance or more (e.g., a third state), the positions of conduit 411 and conduit 421 may not correspond to each other. For example, the cross-sections of conduit 411 and conduit 421 may not overlap. As another example, audio signals or sounds generated from speaker 340 may be output to the outside of second housing 420 only through first conduit 411.

[0183] In an embodiment, the piping state can be a first state when the movement distance of the display (e.g., display 320) relative to the first housing 410 is within a predetermined range (e.g., a first range). For example, the first range can be the range in which the first piping 411 and the second piping 421 overlap with each other. As another example, the first range can represent the range in which the display (e.g., display 320) does not move.

[0184] In an embodiment, the conduit state can be a second state when the movement distance of the display (e.g., display 320) relative to the first housing 410 is within a predetermined range (e.g., a second range). For example, the second range can be the range in which the display 320 has moved to a distance where the second conduit 421 overlaps with the first conduit 411.

[0185] In an embodiment, the piping state can be a third state when the movement distance of the display (e.g., display 320) relative to the first housing 410 is within a predetermined range (e.g., a third range). For example, the third range can be the range of distances by which the display 320 moves to the first piping 411 and the second piping 421 without overlapping each other.

[0186] In an embodiment, the third range may be a range in which the display 320 moves a greater distance relative to the first housing 410 compared to the first and second ranges.

[0187] In an embodiment, the second range may be a range in which the display 320 moves a greater distance relative to the first housing 410 compared to the first range.

[0188] Figure 19-1 to Figure 19-2 An auxiliary structure for assisting the movement (or extension) and fixation of the display of an electronic device including a speaker is shown in the embodiment.

[0189] In one embodiment, the electronic device 201 may include a first housing 510 and a second housing 520. In another embodiment, the second housing 520 may be coupled to the first housing 510 so that it is movable relative to the first housing 510.

[0190] In one embodiment, a conduit 511 for outputting audio signals or sound generated from a loudspeaker (e.g., loudspeaker 540) may be formed in the first housing 510. The conduit 511 may be formed in the shape of a plurality of holes.

[0191] In the embodiments, reference is made to Figure 19-1 to Figure 19-2 For ease of explanation, the second housing 520 can be shown by dividing it into an inner housing 520-1 and an outer housing 520-2.

[0192] In an embodiment, a mounting hole 511-1 for securing a display (e.g., display 320) may be formed through the inner housing 520-1 of the second housing 520. For example, the mounting hole 511-1 may be formed at a position corresponding to a conduit 511 formed in the second housing 520. As another example, the mounting hole 511-1 may be formed in the shape of a plurality of holes.

[0193] In an embodiment, the fixing protrusion 525, which is fixed to the fixing hole 511-1 formed in the inner housing 520-1, can be arranged on the outer housing 520-2 of the second housing 520.

[0194] In an embodiment, the fixing protrusion 525 can be fixed to the fixing hole 511-1 to assist in fixing the display (e.g., display 320) or the second housing 520.

[0195] In an embodiment, when the fixing hole 511-1 and the fixing protrusion 525 coincide, the display (e.g., display 320) or the second housing 520 can be fixed.

[0196] Figure 20-1 to Figure 20-3 The illustration shows the movement (or expansion) of a display, including a speaker, from various aspects of the electronic device in the embodiment. Reference will be made to... Figure 20-1 to Figure 20-3 Detailed description of the formation of reference Figure 19-1 to Figure 19-2 The operation of the electronic device 201 described in terms of the fixing hole 511-1 and the fixing protrusion 525.

[0197] In the embodiments, reference is made to Figure 20-1 When the fixing hole 511-1 and the fixing protrusion 525 coincide, the second housing 520 is fixed. In an embodiment, the fixing protrusion 525 can be seated at a position corresponding to the fixing hole 511-1 to allow the second housing 520 to be fixed. In an embodiment, when the second housing 520 is fixed, the hole of the conduit 511 and the hole of the conduit 521 of the second housing 520 can coincide.

[0198] In the embodiments, reference is made to Figure 20-2The second housing 520 is shown in a fixed state from its side surface. In an embodiment, the second housing 520 can be fixed by attaching the fixing protrusion 525 to the fixing hole 511-1. In an embodiment, the holes of the conduit 511 and the conduit 521 can coincide, so that audio signals or sounds generated from the speaker 340 can pass through the conduits 511 and 521 to be output to the outside of the second housing 520.

[0199] In the embodiments, reference is made to Figure 20-3 The fixing protrusion 525 moves left and right and is fixed to the fixing hole 511-1. For example, there may be multiple fixing protrusions 525. Furthermore, the fixing protrusion 525 may be seated in at least a portion of the multiple fixing holes 511-1 to which it is fixed. As another example, the fixing protrusion 525 may move into a hole formed in the moving direction of the second housing 520 within the fixing hole 511-1. The fixing protrusion 525 can be seated in the fixing hole (511-1) formed in the moving direction of the second housing 520, thus the second housing 520 can be fixed.

[0200] Figure 21-1 to Figure 21-8 The characteristics of the audio signal based on the movement (or expansion) of the display of the electronic device including the speaker are specifically illustrated in the embodiments.

[0201] In an embodiment, Figure 21-1 to Figure 21-8 The characteristics of the audio signal are shown when the second housing 520 moves or expands along with the display (e.g., display 320) of the electronic device 201. In an embodiment, the characteristics of the audio signal may be those of the audio signal output by the speaker 340, and include at least frequency characteristics and / or volume characteristics.

[0202] In an embodiment, Figure 21-1 The illustration shows a state where the display (e.g., display 320) or the second housing 520 is stationary. In embodiments, the distance the display (e.g., display 320) or the second housing 520 moves in each figure can be increased, from... Figure 21-2 Move to Figure 21-8 .

[0203] In an embodiment, as the movement distance of the display (e.g., display 320) or the second housing 520 increases, the area of ​​overlap between conduits 511 and 521 can be smaller, and the ratio of audio signals generated from the speaker (e.g., speaker 340) to be output to the outside only through conduit 511 can also be increased.

[0204] In the embodiment, when pipes 511 and 521 are present, as follows: Figure 21-2When the areas shown partially overlap, the volume of the audio signal generated from the speaker (e.g., speaker 340) can be reduced.

[0205] In the embodiment, from Figure 21-2 Move to Figure 21-6 The area of ​​overlap between conduits 511 and 521 is reduced, and the ratio of audio signals from the speaker (e.g., speaker 340) output solely through conduit 511 can be increased. In an embodiment, from Figure 21-2 Move to Figure 21-6 The volume of the audio signal can be gradually increased, and the frequency loss in the low-frequency band and high-frequency band can be improved more and more.

[0206] In the embodiments, such as Figure 21-7 In the case where only a small portion of the pipe 511 overlaps with the pipe shown, and Figure 21-2 Compared to the situation in 21-6, frequency loss in both low and high frequency bands can be further improved.

[0207] In an embodiment, the movement distance of the display (e.g., display 320) or the second housing 520 is as follows: Figure 21-8 The diagram illustrates that, at a predetermined distance or greater, the audio signal generated from the speaker (e.g., speaker 340) can be output to the outside solely through conduit 511. In this embodiment, in... Figure 21-8 In certain cases, audio characteristics, including at least volume, tone quality, and / or frequency characteristics, can be improved.

[0208] Figure 22 The embodiment specifically illustrates the process by which an electronic device including a speaker corrects the characteristics of an audio signal corresponding to a pipeline state using a filter.

[0209] According to an embodiment, in operation 2210, an audio signal can be generated from the speaker of the electronic device 201.

[0210] According to an embodiment, in operation 2220, the electronic device 201 can tune the generated audio signal.

[0211] In this embodiment, there is an area (C) covered by the second housing 520, so the total effective area (H) of the conduit can be determined by the sum of the effective area (A) of conduit 511 and the effective area (B) of the overlap between conduits 511 and 521. The effective area can represent the actual area on which the audio signal or volume generated from the speaker 340 can be output to the outside.

[0212] In an embodiment, the audio output volume can be maximized when the effective area (A) of the conduit 511 is maximized, and the audio output volume can be reduced as the effective area (B) of the conduit 511 and the conduit 521 overlapping each other and the area (C) covered by the second housing 520 increase.

[0213] In an embodiment, when applying a correction filter (e.g., a first correction filter, a second correction filter, and a third correction filter) for each of the travel distances (e.g., a first range, a second range, and a third range) and / or conduit states (e.g., a first state, a second state, and a third state) under the control of processor 310, electronic device 201 may apply the correction filter taking into account the area ratios mentioned above. For example, under the control of processor 310, electronic device 201 may perform volume compensation for the area (C) covered by the second housing 520, volume compensation taking into account the audio characteristics of the effective area (A) of conduit 511 and the ratio of the effective area (A) of conduit 511 to the total effective area (H) of the conduit, and volume compensation taking into account the audio characteristics of the effective area (B) of conduit 511 and conduit 521 overlapping each other in the effective area (B) taking into account the ratio of the effective area (B) to the total effective area (H).

[0214] According to an embodiment, in operation 2230, the electronic device 201 can correct the volume of the audio signal.

[0215] In an embodiment, without applying a correction filter, the electronic device 201 can measure and store the volume for each of the travel distances (e.g., a first range, a second range, and a third range) and / or states (e.g., a first state, a second state, and a third state). For example, under the control of the processor 310, the electronic device 201 can measure the volume in the first state, the second state, and / or the third state (or the first range, the second range, and / or the third range) before correction and store that volume in the memory 350.

[0216] In an embodiment, under the control of the processor 310, the electronic device 201 can correct the audio output of the first state (or first range) and the second state (or second range) so that the volume is the same as the volume in the third state (or third range) which serves as the reference for audio output correction.

[0217] In one embodiment, under the control of the processor 310, the electronic device 201 can adjust the audio AMP output (e.g., VIAMP) to perform additional volume correction.

[0218] According to an embodiment, in operation 2240, the electronic device 201 can adjust the amplitude of the audio signal for each frequency band segment.

[0219] According to the embodiments, reference will be made to Figure 23 Description of operation 2240, Figure 23 Specifically, an embodiment of a process is shown in which an electronic device including a loudspeaker uses a filter to correct the characteristics of the audio signal corresponding to the pipeline state (or movement distance) for each segment.

[0220] In an embodiment, under the control of the processor 310, the electronic device 201 can measure the audio output for which volume correction has been performed corresponding to the movement distance (e.g., a first range, a second range, and a third range) and / or pipeline state (e.g., a first state, a second state, and a third state).

[0221] In an embodiment, under the control of processor 310, electronic device 201 can perform correction by dividing the measured audio output into multiple frequency bands. For example, refer to... Figure 23 Under the control of processor 310, electronic device 201 can divide the audio output into first to fifth segments. Under the control of processor 310, electronic device 201 can configure the center frequency based on the areas of greater difference in the audio output in the third state (or third range), and adjust the limiter, start time, release time, gain, etc. for each of the first to fifth segments.

[0222] In this embodiment, the division of the audio output is not limited to the first to fifth segments, and there may be no restriction on the segmentation.

[0223] According to an embodiment, in operation 2250, the electronic device 201 can adjust the amplification of the audio signal.

[0224] In an embodiment, even after operations 2210 to 2240 are performed under the control of processor 310, when there is a difference compared to the audio output in the third state (or third range), the electronic device 201 can perform correction by applying an AM filter. In an embodiment, by adjusting the center frequency, bandwidth, and gain under the control of processor 310, the electronic device 201 can adjust the audio output to maintain an output that is the same as or similar to the audio output corresponding to the reference state (e.g., the third state or third range).

[0225] According to an embodiment, in operation 2260, electronic device 201 can output an audio signal to the outside. For example, electronic device 201 can perform audio output correction according to operations 2210 to 2250, and then output the audio signal to the outside of electronic device 201.

[0226] Figure 24 The structure of an electronic device based on the characteristics of an audio signal corresponding to median correction and pipeline status (or travel distance) in an embodiment is shown.

[0227] In the embodiments, reference is made to Figure 24 The second housing 520 of the electronic device 201 can be fixed to a position that is not aligned with a predefined position, rather than to a predefined position, based on a fixing protrusion (e.g., fixing protrusion 525) and a fixing hole (e.g., fixing hole 511-1), in order to maintain a specific aspect ratio.

[0228] In an embodiment, a fixing protrusion (e.g., fixing protrusion 525) and a fixing hole (e.g., fixing hole 511-1) can be fixed at the aligned positions of the fixing protrusion and the fixing hole. In an embodiment, under the control of the processor 310, the electronic device 201 can apply a correction filter having a median value of the applied correction filter defined before and after the aligned hole.

[0229] In an embodiment, when the holes of conduit 511 and conduit 521 are aligned in the nth fixing hole, the electronic device 201 can interpolate the midpoint between the value of the correction filter when they coincide at the nth fixing hole and the value of the correction filter when they coincide at the (n+1)th fixing hole, and apply the interpolated value.

[0230] Figure 25 The embodiment illustrates the operation of the electronic device for the user interface when the display of the electronic device is moved rapidly.

[0231] In one embodiment, without intermediate steps, a user can change the state of electronic device 201 from an unextended state (or a slide-in state) of the display (e.g., display 320) to a fully extended state (or a slide-out state) of the display (e.g., display 320). In another embodiment, without intermediate steps, a user can change the state of electronic device 201 from a fully extended state of the display (e.g., display 320) to an unextended state of the display (e.g., display 320).

[0232] In this embodiment, under the control of the processor 310, the electronic device 201 can apply fade-in or fade-out effects to the audio output, thereby providing the user with a user experience consistent with the physical changes of the electronic device 201.

[0233] In an embodiment, when changing from a slide-out state to a slide-in state at the same volume level, if the overlap area of ​​pipes 511 and 521 increases and the total volume decreases by 3dB, the electronic device 201, under the control of the processor 310, can increase the audio output by 3dB and sequentially apply volume compensation and audio output amplification adjustment for each frequency band.

[0234] In an embodiment, under the control of processor 310, electronic device 201 can detect the movement distance of the display (e.g., display 320), and divide the movement distance into the total extension distance (D) according to the distance of each step of the audio signal, thereby applying a correction filter. For example, if the audio output changes by 0.5 dB, electronic device 201, under the control of processor 310, can change the audio output in 0.5 dB increments for every D / 6 distance, so that the user can perceive the change as a continuous sound change.

[0235] In this embodiment, the steps by which the electronic device 201 changes the audio output according to the distance are not limited to the above six steps, and can be further simplified or subdivided.

[0236] Figure 26-1 to Figure 26-4 This is a view illustrating a user interface in an embodiment where audio output can be selectively corrected.

[0237] In an embodiment, the electronic device (e.g., electronic device 201) may selectively perform the function of correcting audio output according to user configuration.

[0238] In the embodiments, reference is made to Figure 26-1 When a user wants to perform calibration of the natural audio output based on the extension or movement of the display (e.g., display 320) of the electronic device (e.g., electronic device 201), the user can configure the audio output calibration to be on or in a "used" state. In this case, for example, when the display 320 of electronic device 201 extends or moves, the electronic device, under the control of processor 310, can perform audio output calibration based on the distance of movement (e.g., a first range, a second range, and a third range) and / or the pipeline state (e.g., a first state, a second state, and a third state).

[0239] In an embodiment, if the configuration for correcting the audio output of the electronic device 201 is configured to a "in use" state, the electronic device 201, under the control of the processor 310, can provide the user with an output that applies audio output correction regardless of the corresponding pipeline state.

[0240] In one embodiment, for the configuration of correcting the audio output, the user can configure the electronic device 201 to perform audio output correction only when the display (e.g., display 320) is slid out. In this case, under the control of the processor 310, the electronic device 201 can perform audio output correction only when the display 320 is slid out.

[0241] In one embodiment, for the configuration of correcting the audio output, the user can configure the electronic device 201 to perform audio output correction only when the display (e.g., display 320) is slid in. In this case, under the control of the processor 310, the electronic device 201 can perform audio output correction only when the display 320 is slid in.

[0242] In the embodiments, reference is made to Figure 26-2 When a user does not want to perform audio output calibration based on the expansion or movement of the display (e.g., display 320) of the electronic device (e.g., electronic device 201), the user can configure the audio output calibration to be off or in a "not in use" state. In this case, for example, even if the display 320 of electronic device 201 expands or moves, the electronic device may not perform audio output calibration based on the distance of movement (e.g., a first range, a second range, and a third range) and / or the pipeline state (e.g., a first state, a second state, and a third state).

[0243] In the embodiments, reference is made to Figure 26-3 Under the control of processor 310, electronic device 201 can provide the user with a preview of the calibrated audio output. For example, when the user configures the system to "not in use," electronic device 201 can, under the control of processor 310, not perform audio output calibration and can provide the user with a preview of the audio output based on different pipe states. As another example, when the user configures the system to "in use," electronic device 201 can, under the control of processor 310, perform audio output calibration and provide the user with a preview of the audio output calibrated based on each pipe state.

[0244] In the embodiments, reference is made to Figure 26-4 Under the control of processor 310, electronic device 201 can display a graph on display 320 showing the characteristics of audio output based on travel distance (e.g., a first range, a second range, and a third range) and / or pipeline state (e.g., a first state, a second state, and a third state), thereby providing the user with information about the characteristics of the audio output. For example, in Figure 26-3 In the preview state described, if the user selects a movement distance (e.g., a first range, a second range, and a third range) and / or a conduit state (e.g., a first state, a second state, and a third state), the electronic device 201, under the control of the processor 310, can respond to the selection and display a graph on the display 320 showing the characteristics of the audio output corresponding to the movement distance and / or the conduit state. As another example, even without any selected user input, the electronic device 201, under the control of the processor 310, can also display a graph on the display 320 showing the characteristics of the audio output corresponding to the movement distance and / or the conduit state.
