Description

Technical Field

[0001] The present disclosure relates to a foldable electronic device including a plurality of speakers and a method of operating the foldable electronic device. Background Art

[0002] The functional differences between electronic devices from various manufacturers have been substantially reduced, and electronic devices have therefore become thinner to meet the purchasing needs of consumers, and have been improved to enhance the design aspects and distinguish their functional elements. With the development of display technology, active research and development has been carried out on electronic devices with flexible displays (or rollable displays). Electronic devices have gradually evolved from unilateral rectangular shapes to more diverse shapes. For example, the development of flexible electronic devices with flexible displays has been carried out, and the flexible display is applied to the flexible electronic device so that the flexible display can be folded, bent, rolled up or unfolded. The foldable electronic device can have at least two shells that are foldably connected, so that the foldable electronic device can be easily carried, and a large screen display can be obtained when the foldable electronic device is used. The foldable electronic device may include a hinge device (e.g., a hinge structure) configured to connect at least two shells and a plurality of speakers arranged in at least two shells.

[0003] The above description is provided as background information only to help understand the embodiments of the present disclosure. It has not been determined whether any of the above descriptions are applicable to the prior art related to the present disclosure, and no claims have been made. Summary of the invention

[0004] Technical issues

[0005] A plurality of speakers may be provided in a foldable electronic device, and space limitations make it difficult to have a flat frequency response characteristic in all audible frequency bands with only the characteristics of the speaker itself. Sound filters and tuning parameters may be used to tune the frequency response characteristics of the speaker, but the trade-off between the high frequency band, the mid-frequency band, and the low frequency band makes it difficult to have a flat frequency response characteristic in all audible frequency bands. In particular, the frequency response characteristics of the speaker may deteriorate in the low frequency band and the high frequency band. A foldable electronic device may have a plurality of speakers provided in two housings, and it is necessary to control the output characteristics of the speaker according to the folding state (e.g., the folded state, the flat state). In the folded state of the foldable electronic device, a first speaker provided in the first housing and a second speaker provided in the second housing are close to each other (e.g., adjacent). If the first speaker and the second speaker are provided close to each other (e.g., adjacent), the sound waves outputted may cancel each other out, thereby reducing the entire sound output. An embodiment of the present disclosure may provide a foldable electronic device including a plurality of speakers and a method for operating the foldable electronic device, wherein the sound output characteristics of the speakers are selectively controlled according to the folded state and the flat state of the foldable electronic device, thereby ensuring a flat frequency response characteristic in all audible frequency bands. Another embodiment of the present disclosure may provide a foldable electronic device including a plurality of speakers and a method for operating the foldable electronic device, wherein the phases of sound waves output from the plurality of speakers are selectively controlled according to the folded state and the flat state of the foldable electronic device, thereby preventing the sound output from being reduced.

[0006] The technical problems to be solved by the present disclosure are not limited to the above-mentioned technical problems, and other technical problems not mentioned herein will be clearly understood by those skilled in the art to which the present disclosure belongs from the following description.

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 supporting direct (e.g., wired) communication or wireless communication. According to an 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).

[0076] In an embodiment, the speaker unit 210 may include a plurality of speakers 211, 212, 213, and 214. For example, among the plurality of speakers 211, 212, 213, and 214, the first speaker 211 (e.g., Figure 7 The first speaker 740 and the second speaker 212 (eg Figure 7 The second speaker 750 in the first housing (eg, Figure 3a and Figure 3b For example, among the plurality of speakers 211, 212, 213 and 214, the third speaker 213 (for example, Figure 7 760) and the fourth speaker 214 (e.g., Figure 7 The fourth speaker 770 in the embodiment may be disposed in the second housing (eg, Figure 3a and Figure 3b In the second shell structure 312).

[0077] For example, the electronic device 200 (eg, Figure 3a and Figure 3b The electronic device 300, Figure 4 and Figure 5 The electronic device 400, Figure 7 and Figure 8 The frequency response characteristics and stereo output of the plurality of speakers 211, 212, 213, and 214 are controlled by switching the electronic device 700) to a first state (e.g., a flat state) or a second state (e.g., a folded state).

[0078] For example, the electronic device 200 (eg, Figure 3a and Figure 3b The electronic device 300, Figure 4 and Figure 5 The electronic device 400, Figure 7 and Figure 8 The phases of sound waves output from the plurality of speakers 211, 212, 213, and 214 are controlled by adjusting the first state (e.g., a flat state) or the second state (e.g., a folded state) of the electronic device 700 in FIG.

[0079] In an embodiment, the processor 220 may determine that the electronic device 200 (eg, Figure 3a and Figure 3b The electronic device 300, Figure 4 and Figure 5 The electronic device 400, Figure 7 and Figure 8 For example, the processor 220 may control the audio DSP 240 so that the frequency response characteristics and stereo output of the plurality of speakers 211, 212, 213, and 214 are controlled according to the first state (e.g., flat state) or the second state (e.g., folded state) of the electronic devices 200, 300, 400, and 700.

[0080] For example, the processor 220 can control the audio DSP 240 so that the phase of sound waves output from multiple speakers 211, 212, 213 and 214 is controlled according to the first state (e.g., flat state) or the second state (e.g., folded state) of the electronic devices 200, 300, 400 and 700.

[0081] In an embodiment, the memory 230 may be operably connected to the processor 220. For example, the memory 230 may store instructions for controlling the frequency response characteristics and stereo output of the plurality of speakers 211, 212, 213, and 214 according to a first state (e.g., a flat state) or a second state (e.g., a folded state) of the electronic devices 200, 300, 400, and 700.

[0082] For example, the memory 230 may store instructions for controlling the phase of sound waves output from multiple speakers 211, 212, 213, and 214 according to a first state (e.g., a flat state) or a second state (e.g., a folded state) of the electronic devices 200, 300, 400, and 700.

[0083] For example, the memory 230 may store various pieces of data for the processor 220, the audio DSP 240, and the sensor module 270 of the electronic devices 200, 300, 400, and 700. The data stored in the memory 230 may include, for example, software (e.g., Figure 1 140) and input data or output data about commands related to the software. The memory 230 may include volatile memory (e.g., Figure 1 volatile memory 132 in ) or non-volatile memory (e.g., Figure 1 The non-volatile memory 134 in the memory.

[0084] In an embodiment, the audio DSP 240 may change the sampling ratio relative to one or more digital audio signals, apply one or more filters, process interpolation, amplify or attenuate all or some frequency bands, process noise (e.g., attenuate noise or echo), change channels (e.g., switch between mono and stereo), perform mixing or extract a specified signal. Depending on the embodiment, one or more functions of the audio signal processor 240 may be implemented as an equalizer.

[0085] In an embodiment, when sound waves are output through multiple speakers 211, 212, 213 and 214, the audio DSP 240 can control at least one of the frequency response characteristics of the multiple speakers 211, 212, 213 and 214, the stereo output of the multiple speakers 211, 212, 213 and 214, and the phase of the output sound waves according to the first state (e.g., a flat state) or the second state (e.g., a folded state) of the electronic devices 200, 300, 400 and 700 based on the control of the processor 220.

[0086] For example, the audio DSP 240 can control the frequency response characteristics and stereo output of multiple speakers 211, 212, 213 and 214 according to the first state (e.g., flat state) or the second state (e.g., folded state) of the electronic devices 200, 300, 400 and 700 based on the control of the processor 220.

[0087] For example, the audio DSP 240 can control the phase of sound waves output from multiple speakers 211, 212, 213 and 214 according to the first state (e.g., flat state) or the second state (e.g., folded state) of the electronic devices 200, 300, 400 and 700 based on the control of the processor 220.

[0088] Despite Figure 2 The processor 220 and the audio DSP 240 are shown as separate components, but some or all of the functions of the audio DSP 240 may be incorporated by the processor 220. Some or all of the functions of the audio DSP 240 may be implemented as hardware or software.

[0089] In an embodiment, the voice input device 250 may include at least one microphone. For example, when the voice input device 250 includes a single microphone, the single microphone may be disposed on the first housing (eg, Figure 3a and Figure 3b The first shell structure 311) or the second shell (for example, Figure 3a and Figure 3b For example, when the voice input device 250 includes multiple microphones, the first microphone can be disposed in the first housing (eg, Figure 3a and Figure 3b , and the second microphone may be disposed in the second housing (eg, Figure 3a and Figure 3b In the second shell structure 312).

[0090] In an embodiment, the display module 260 may be disposed in a housing (eg, Figure 3a and Figure 3b The display module 260 may include a flexible display or a foldable display.

[0091] In an embodiment, the sensor module 270 may include a plurality of sensors 271, 272, and 273. For example, the sensor module 270 may include a Hall sensor 271, an optical sensor 272, and a gyro / acceleration sensor 273.

[0092] For example, the sensor module 270 may sense the operating state (e.g., a flat state, a folded state, an intermediate state) of the electronic devices 200, 300, 400, and 700. The sensor module 270 may generate an electrical signal or a data value corresponding to the sensed state, and may provide the electrical signal or the data value to the processor 220. The sensor module 270 may include not only a Hall sensor 271, an optical sensor 272, and a gyro / acceleration sensor 273, but also a gesture sensor, an atmospheric pressure sensor, a magnetic 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.

[0093] For example, the processor 220 may determine whether the electronic devices 200 , 300 , 400 , and 700 are in a first state (eg, a flat state) or a second state (eg, a folded state) based on sensing data input from the sensor module 270 .

[0094] For example, the processor 220 may determine whether the electronic devices 200 , 300 , 400 , and 700 are in a third state (eg, an intermediate state between the unfolded state and the folded state) based on sensing data input from the sensor module 270 .

[0095] For example, the processor 220 may determine whether the electronic devices 200 , 300 , 400 , and 700 are transitioning from a first state (eg, a flat state) to a second state (eg, a folded state) based on sensing data input from the sensor module 270 .

[0096] For example, the processor 220 may determine whether the electronic devices 200 , 300 , 400 , and 700 are transitioning from the second state (eg, folded state) to the first state (eg, flat state) based on sensing data input from the sensor module 270 .

[0097] Figure 3a A first state (eg, a flat state, an opened state) of the electronic device according to various embodiments of the present disclosure is shown. Figure 3b A second state (eg, folded state, closed state) of the electronic device according to various embodiments of the present disclosure is shown.

[0098] refer to Figure 3a and Figure 3b , the electronic device 300 (eg, Figure 1 The electronic device 101, Figure 2 The electronic device 200, Figure 4 and Figure 5 The electronic device 400, Figure 7 and Figure 8 The electronic device 700 may include a housing 310 and a display 320 (eg, Figure 1 The display module 160, Figure 7 and Figure 8 In an embodiment, the display 320 may include a flexible display or a foldable display.

[0099] According to an embodiment, the surface on which the display 320 is provided may be defined as the first surface or the front surface of the electronic device 300 (e.g., the surface on which the screen is displayed when unfolded). The surface opposite to the front surface may be defined as the second surface or the rear surface of the electronic device 300. The surface surrounding the space between the front surface and the rear surface may be defined as the third surface or the side surface of the electronic device 300. For example, the electronic device 300 may have a folding area 323 that is folded or unfolded in a first direction (e.g., the x-axis direction) relative to the folding axis (e.g., the A-axis).

[0100] In an embodiment, the housing 310 may include a first housing structure 311, a second housing structure 312 including a sensor region 324, a first back cover 380, and / or a second back cover 390. The type and connection of the housing 310 of the electronic device 300 are not limited to Figure 3a and Figure 3b The types and connections shown in , and can be implemented by combinations and / or connections of other shapes or components. In an embodiment, the first housing structure 311 and the first back cover 380 can be integrally formed, and the second housing structure 312 and the second back cover 390 can be integrally formed.

[0101] In an embodiment, the first housing structure 311 and the second housing structure 312 may be disposed on both sides of the folding axis A, and may be formed to be overall symmetrical with respect to the folding axis A. The angle between the first housing structure 311 and the second housing structure 312 may vary depending on whether the electronic device 300 is in a first state (e.g., a flat state), in a second state (e.g., a folded state), or in a third state (e.g., an intermediate state between the unfolded state and the folded state).

[0102] In an embodiment, unlike the first housing structure 311, the second housing structure 312 may further include a sensor area 324 in which various sensors (e.g., an illumination sensor, an iris sensor, and / or an image sensor) are disposed, but may be formed in other areas to be symmetrical with the first housing structure 311. As another example, the sensor area 324 may be disposed in the first housing structure 311 or omitted.

[0103] In an embodiment, in addition to the sensor area 324, at least one sensor (eg, a camera module, an illumination sensor, an iris sensor, and / or an image sensor) may be disposed under the display and / or in the bezel area.

[0104] In an embodiment, the first housing structure 311 and the second housing structure 312 may form a recess in which the display 320 is accommodated. In the illustrated embodiment, due to the sensor area 324, the recess may have two or more different widths in a direction perpendicular to the folding axis A (eg, the x-axis direction).

[0105] For example, the recess may have a first width W1 between the first portion 311a of the first housing structure 311 and the first portion 312a of the second housing structure 312, which is formed on the periphery of the sensor region 324 in the second housing structure 312. The recess may have a second width W2 formed by the second portion 311b of the first housing structure 311 and the second portion 312b of the second housing structure 312, which is substantially parallel to the folding axis A in the first housing structure 311, and the second portion 312b of the second housing structure 312, which is in the second housing structure 312, does not correspond to the sensor region 324, and is substantially parallel to the folding axis A. In this case, the second width W2 may be formed to be longer than the first width W1. In other words, the first portion 311a of the first housing structure 311 and the first portion 312a of the second housing structure 312, which have shapes asymmetrical to each other, may form the first width W1 of the recess. The second portion 311 b of the first case structure 311 and the second portion 312 b of the second case structure 312 , which have shapes symmetrical to each other, may form a second width W2 of the recess.

[0106] In an embodiment, the first portion 312a and the second portion 312b of the second housing structure 312 may have different distances from the folding axis A. The width of the recess is not limited to the example shown. In various embodiments, the recess may have multiple widths by the type of sensor area 324 or the asymmetrical shape of the first housing structure 311 and the second housing structure 312.

[0107] In an implementation, the first case structure 311 and the second case structure 312 may have at least a portion made of a metal or non-metal material having a selected amount of rigidity to support the display 320 .

[0108] In an embodiment, the sensor region 324 may be formed to have a predetermined area adjacent to a corner of the second housing structure 312. However, the arrangement, shape, and size of the sensor region 324 are not limited to the illustrated example. For example, the sensor region 324 may be disposed on another corner of the second housing structure 312 or in an area between a top corner and a bottom corner of the second housing structure 312.

[0109] In an embodiment, components for performing various functions embedded in the electronic device 300 may be exposed to the front surface of the electronic device 300 through the sensor area 324 or one or more openings provided in the sensor area 324. In various embodiments, the components may include various types of sensors. The sensor may include, for example, at least one of an illumination sensor, a front camera (e.g., a camera module), an earpiece, or a proximity sensor.

[0110] In an embodiment, the first back cover 380 may be disposed on one side of the folding axis A on the rear surface of the electronic device 300, for example, may have a substantially rectangular perimeter, and the perimeter may be surrounded by the first housing structure 311. As another example, the second back cover 390 may be disposed on the other side of the folding axis A on the rear surface of the electronic device, and may have a perimeter surrounded by the second housing structure 312.

[0111] In an embodiment, the first rear cover 380 and the second rear cover 390 may have a substantially symmetrical shape around the folding axis A. However, the first rear cover 380 and the second rear cover 390 do not necessarily have a symmetrical shape, and in another embodiment, the electronic device 300 may include various shapes of the first rear cover 380 and the second rear cover 390. In another embodiment, the first rear cover 380 may be integrally formed with the first housing structure 311, and the second rear cover 390 may be integrally formed with the second housing structure 312.

[0112] In an embodiment, the first rear cover 380, the second rear cover 390, the first housing structure 311, and the second housing structure 312 may form a space in which various components of the electronic device 300 (e.g., a printed circuit board or a battery) may be disposed. In an embodiment, one or more components of the electronic device 300 may be disposed or visibly exposed on the rear surface of the electronic device 300. For example, at least a portion of the sub-display 330 may be visibly exposed through the first rear region 382 of the first rear cover 380. In an embodiment, one or more components or sensors may be visibly exposed through the second rear region 392 of the second rear cover 390. In various embodiments, the sensor may include an illumination sensor, a proximity sensor, and / or a rear camera.

[0113] In an embodiment, the hinge cover 313 can be disposed between the first housing structure 311 and the second housing structure 312 and configured to cover internal components (e.g., hinge structure). The hinge cover 313 can cover adjacent parts of the first housing structure 311 and the second housing structure 312 by unfolding and folding the electronic device 300.

[0114] In an embodiment, the hinge cover 313 may be partially covered by or exposed to the outside of the first housing structure 311 and the second housing structure 312 according to the first state (e.g., flat state) or the second state (e.g., folded state) of the electronic device 300. In an embodiment, when the electronic device 300 is in the first state (e.g., flat state), the hinge cover 313 may be covered by the first housing structure 311 and the second housing structure 312 and thus not exposed.

[0115] In an embodiment, when the electronic device 300 is in a second state (e.g., a folded state) (e.g., a fully folded state), the hinge cover 313 may be exposed to the outside between the first housing structure 311 and the second housing structure 312. In an embodiment, in a third state (e.g., an intermediate state) in which the first housing structure 311 and the second housing structure 312 are folded at a certain angle, the hinge cover 313 may be partially exposed to the outside between the first housing structure 311 and the second housing structure 312. However, the exposed area in this case may be smaller than the exposed area in the fully folded state. In an embodiment, the hinge cover 313 may include a curved surface.

[0116] In an embodiment, the display 320 may be disposed in a space formed by the housing 310. For example, the display 320 may be placed in a recess formed by the housing 310, and may form most of the front surface of the electronic device 300.

[0117] In an embodiment, the front surface of the electronic device 300 may include a display 320 and a partial area of ​​the first housing structure 311 adjacent to the display 320 and a partial area of ​​the second housing structure 312 adjacent to the display 320. The rear surface of the electronic device 300 may include a first back cover 380, a partial area of ​​the first housing structure 311 adjacent to the first back cover 380, a second back cover 390, and a partial area of ​​the second housing structure 312 adjacent to the second back cover 390.

[0118] In an embodiment, the display 320 may refer to a display having at least a partial area configured to be deformed into a flat or curved shape. In an embodiment, the display 320 may include a folding area 323, a side ( Figure 3a The first area 321 on the left side of the folding area 323 and the other side ( Figure 3a A second area 322 on the right side of the image.

[0119] In an embodiment, the display 320 may include a top-emitting or bottom-emitting OLED display. The OLED display may include a low temperature color filter (LTCF) layer, a window glass (e.g., ultra-thin glass (UTG) or a polymer window) and / or an optical compensation film (e.g., an optical compensation film (OCF)). The LTCF layer of the OLED display may replace a polarizing film (or polarizing layer).

[0120] The area division of the display 320 is exemplary, and the display 320 may be divided into a plurality of (e.g., two or more) areas according to structure or function. In an embodiment, the area of ​​the display 320 may be divided by the folding area 323 or the folding axis A extending parallel to the y-axis, but in another embodiment, the area of ​​the display 320 may be divided with reference to another folding area (e.g., a folding area parallel to the x-axis) or another folding axis (e.g., a folding axis parallel to the x-axis).

[0121] In an implementation, the first region 321 and the second region 322 may have shapes that are overall symmetrical around the folding region 323 .

[0122] Hereinafter, operations of the first case structure 311 and the second case structure 312 and respective regions of the display 320 according to states (eg, a flat state and a folded state) of the electronic device 300 will be described.

[0123] In an embodiment, when the electronic device 300 is in a flat state (eg, Figure 3a), the first housing structure 311 and the second housing structure 312 may be arranged to face substantially the same direction while forming an angle of about 180° between them. The surface of the first area 321 of the display 320 and the surface of the second area 322 of the display 320 may form about 180° between them and may face substantially the same direction (e.g., the forward direction of the electronic device). The folding area 323 may form substantially the same plane with the first area 321 and the second area 322.

[0124] In an embodiment, when the electronic device 300 is in a folded state (eg, Figure 3b ), the first housing structure 311 and the second housing structure 312 may be arranged to face each other. The surface of the first area 321 of the display 320 and the surface of the second area 322 of the display 320 may face each other while forming a narrow angle (e.g., about 0° to 10°) therebetween. At least a portion of the folding area 323 may be configured as a curved surface having a predetermined curvature.

[0125] In an embodiment, when the electronic device 300 is in a semi-folded state, the first housing structure 311 and the second housing structure 312 may be arranged at a certain angle to each other. The surface of the first area 321 of the display 320 and the surface of the second area 322 of the display 320 may form an angle greater than that in the folded state and less than that in the flat state. At least a portion of the folding area 323 may be configured as a curved surface having a predetermined curvature that may be less than the curvature in the folded state.

[0126] The electronic device according to various embodiments of the present disclosure may include an electronic device such as a bar type, a foldable type, a rollable type, a sliding type, a wearable type, a tablet PC and / or a laptop PC. The electronic device 200 according to various embodiments of the present disclosure is not limited to the above examples and may include various other electronic devices.

[0127] Figure 4 Sound waves output from a plurality of speakers in a first state (eg, a flat state) of the foldable electronic device are shown. Figure 5 Sound waves output from a plurality of speakers in a second state (eg, a folded state) of the foldable electronic device are shown.

[0128] refer to Figure 4 and Figure 5 The foldable electronic device 400 may include a first housing 410 (eg, Figure 3a and Figure 3b The first shell structure 311 in the embodiment of the present invention), the second shell 420 (for example, Figure 3a and Figure 3ba second shell structure 312 in the first shell, a hinge unit 430 configured to connect the first shell 410 and the second shell 420, a first speaker 440 arranged in the first shell 410, and a second speaker 450 arranged in the second shell 420.

[0129] In an embodiment, when the foldable electronic device 400 is in a first state (eg, a flat state), the first speaker 440 and the second speaker 450 may be connected to the foldable electronic device 400 through the audio DSP (eg, Figure 2 The operation of the audio DSP 240 in the foldable electronic device 400 outputs the sound waves of the same sound source. For example, when the sound source is played in the first state (e.g., the flat state) of the foldable electronic device 400, the first speaker 440 may output the first sound wave 441, and the second speaker 450 may output the second sound wave 451. For example, when the sound source is played in the first state (e.g., the flat state) of the foldable electronic device 400, the first sound wave 441 output from the first speaker 440 and the second sound wave 451 output from the second speaker 450 may have the same phase.

[0130] In an embodiment, when the sound source is played in the second state (eg, folded state) of the foldable electronic device 400, the first speaker 440 and the second speaker 450 may be played through the audio DSP (eg, Figure 2 The audio DSP 240 in the foldable electronic device 400 is operated to output the sound waves of the same sound source. For example, when the sound source is played in the second state (e.g., the folded state) of the foldable electronic device 400, the first speaker 440 may output the first sound wave 441, and the second speaker 450 may output the second sound wave 451. For example, when the foldable electronic device 400 is in the second state (e.g., the folded state), the first housing 410 and the second housing 420 are folded to be adjacent to (e.g., close to) each other relative to the hinge unit 430, and the first speaker 440 and the second speaker 450 are therefore positioned adjacent to (e.g., close to) each other. Therefore, the first sound wave 441 output from the first speaker 440 and the second sound wave 451 output from the second speaker 450 have different phase (e.g., 180°) differences. For example, due to the phase (e.g., 180°) difference between the sound waves 441, 451 output from the first speaker 440 and the second speaker 450, the sound waves 441, 451 may cancel each other, thereby reducing the overall sound output. For example, if the first speaker 440 and the second speaker 450 are configured to have the same output characteristics, there is a limitation on ensuring a flat frequency response characteristic in all audible frequency bands. For example, the frequency response characteristics of at least one of the first speaker 440 and the second speaker 450 may be tuned, but the compromise limitation between the high frequency band, the middle frequency band, and the low frequency band satisfies all characteristics in the high frequency band, the middle frequency band, and the low frequency band.

[0131] Figure 6 A method for configuring tuning values ​​of a plurality of speakers of an electronic device according to an embodiment of the present disclosure is illustrated. Figure 7 A foldable electronic device according to an embodiment of the present disclosure is shown, the foldable electronic device having four speakers disposed thereon, and the foldable electronic device is divided into a first part and a second part to control frequency response characteristics of the speakers. Figure 8 A foldable electronic device according to an embodiment of the present disclosure is shown, the foldable electronic device having four speakers disposed thereon and divided into a first area and a second area to control stereo left and right outputs.

[0132] refer to Figures 6 to 8 , according to an embodiment of the present disclosure, a foldable electronic device 700 (eg, Figure 2 The electronic device 200, Figure 3a and Figure 3b The electronic device 300 in the embodiment may include a first housing 710 (eg, Figure 3a and Figure 3b The first shell structure 311 in the embodiment of the present invention), the second shell 720 (for example, Figure 3a and Figure 3b The second housing structure 312 in the embodiment of the present invention is configured to connect the first housing 710 and the second housing 720 with a hinge unit (eg, Figure 4 and Figure 5 430), the display 730 (eg, FIG. 3 and Figure 4 320) and a plurality of speakers 740, 750, 760 and 770 (e.g., Figure 2 Multiple speakers 211, 212, 213 and 214).

[0133] In an embodiment, the first housing 710 and the second housing 720 may be coupled to be foldable / unfoldable by the hinge unit 430. The display 730 (e.g., a flexible display or a foldable display) may extend from one surface of the first housing 710 to one surface of the second housing 720, and may be arranged to be supported by the first housing 710 and the second housing 720. For example, the display 730 may include a flexible display or a foldable display. For example, the surface on which the display 730 is arranged may be defined as the first surface or the front surface of the electronic device 700 (e.g., the surface on which the picture is displayed when unfolded). The surface opposite to the front surface may be defined as the second surface or the rear surface of the electronic device 700. The surface surrounding the space between the front surface and the rear surface may be defined as the third surface or the side surface of the electronic device 700. For example, the speaker hole 705 may be formed on the side surface of the electronic device 700 so that the sound waves are output to the outside from the plurality of speakers 740, 750, 760, and 770. For example, the display 730 of the electronic device 700 may be folded (eg, folding) or unfolded (eg, unfolding) in a first direction (eg, x-axis direction) relative to a folding axis (eg, A-axis).

[0134] In an embodiment, multiple speakers (e.g., Figure 2 The plurality of speakers 211, 212, 213 and 214, Figure 7 and Figure 8 Multiple speakers 740, 750, 760 and 770) can be set in the first shell 710 and the second shell 720.

[0135] For example, the first speaker 740 and the second speaker 750 may be disposed in the first housing 710. The first speaker 740 may be disposed on the upper side relative to the y-axis inside the first housing 710, and the second speaker 750 may be disposed on the lower side relative to the y-axis. However, not limited thereto, one speaker may be disposed in the first housing 710, and three or more speakers may be disposed in the first housing 710.

[0136] For example, the third speaker 760 and the fourth speaker 770 may be provided in the second housing 720. The third speaker 760 may be provided on the upper side relative to the y-axis inside the second housing 720, and the fourth speaker 770 may be provided on the lower side relative to the y-axis. However, not limited thereto, one speaker may be provided in the second housing 720, and three or more speakers may be provided therein.

[0137] In an embodiment, multiple speakers 740, 750, 760 and 770 can be set in a foldable electronic device 700 according to an embodiment of the present disclosure, and the foldable electronic device 700 can be divided into a first part 701 and a second part 702 to control the frequency response characteristics of the multiple speakers 740, 750, 760 and 770.

[0138] In an embodiment, a plurality of speakers 740 , 750 , 760 , and 770 may be provided in a foldable electronic device 700 according to an embodiment of the present disclosure, and the foldable electronic device 700 may be divided into a first area 703 and a second area 704 to control stereo left input and right output of the plurality of speakers 740 , 750 , 760 , and 770 .

[0139] In an embodiment, according to the folding state of the foldable electronic device 700 (eg, folded state, flat state), the audio DSP (eg, Figure 2 The audio DSP 240 in the processor ( Figure 1 The processor 120, Figure 2 The output characteristics of the plurality of speakers 740, 750, 760, and 770 are controlled under the control of the processor 220 in the processor 220. For example, the output characteristics of the plurality of speakers 740, 750, 760, and 770 may include a first sound output characteristic 601 and a second sound output characteristic 602.

[0140] For example, the processors 120 and 220 may determine whether the foldable electronic device 700 is in a first state (e.g., a folded state), in a second state (e.g., a flat state), or in a third state (e.g., an intermediate state). For example, the processors 120 and 220 may control the audio DSP (e.g., the audio DSP 240) based on the state of the foldable electronic device 700 to control the frequency response characteristics (e.g., the first sound output characteristics 601 and the second sound output characteristics 602) of the plurality of speakers 740, 750, 760, and 770. For example, the audio DSP 240 may selectively apply the tuning values ​​610 and 620 to each of the plurality of speakers 740, 750, 760, and 770 according to the first state (e.g., a folded state), the second state (e.g., a flat state), or the third state (e.g., an intermediate state) of the foldable electronic device 700 based on the control of the processors 120 and 220.

[0141] In an embodiment, depending on the state of the foldable electronic device 700 (e.g., a folded state, a flat state, an intermediate state), the audio DSP 240 can apply a tuning value (e.g., a first tuning value 610) under the control of the processor 220 so that the multiple speakers 740, 750, 760 and 770 all have a first sound output characteristic 601.

[0142] In an embodiment, depending on the state of the foldable electronic device 700 (e.g., a folded state, a flat state, an intermediate state), the audio DSP 240 can apply a tuning value (e.g., a changed tuning value 620) under the control of the processor 220 so that the multiple speakers 740, 750, 760 and 770 all have the second sound output characteristic 602.

[0143] In an embodiment, depending on the state of the foldable electronic device 700 (e.g., a folded state, a flat state, an intermediate state), the audio DSP 240 can apply a tuning value (e.g., a first tuning value 610) under the control of the processor 220 so that some of the multiple speakers 740, 750, 760 and 770 have a first sound output characteristic 601, and can apply a tuning value (e.g., a changed tuning value 620) so that some of the remaining speakers have a second sound output characteristic 602.

[0144] For example, the first tuning value 610 is used to give the speaker the first sound output characteristic 601, and may refer to a value tuned so that one speaker outputs the entire frequency band (e.g., 20 Hz to 20 kHz) of the output frequency. For example, based on the control of the processor 220, the audio DSP 240 may apply the first tuning value 610 to at least one or all of the plurality of speakers 740, 750, 760, and 770 according to the folded state (e.g., folded state, flat state) of the foldable electronic device 700.

[0145] For example, the changed tuning value 620 is used to give the loudspeaker the second sound output characteristic 602, and can refer to a value tuned to make a loudspeaker output a portion of the output frequency band (e.g., high frequency band, middle frequency band). The changed tuning value 620 can include a second tuning value 622 (e.g., high frequency band tuning value) and a third tuning value 624 (e.g., middle / low frequency band tuning value), the second tuning value 622 is tuned to make the loudspeaker output the high frequency band among the second sound output characteristic 602, and the third tuning value 624 is tuned to make the loudspeaker output the middle / low frequency band among the second sound output characteristic 602.

[0146] For example, based on the control of the processor 220, the audio DSP 240 may apply the changed tuning value 620 to all of the plurality of speakers 740, 750, 760, and 770 according to the folding state (e.g., folded state, flat state) of the foldable electronic device 700. However, not limited thereto, based on the control of the processor 220, the audio DSP 240 may apply the changed tuning value 620 to some of the plurality of speakers 740, 750, 760, and 770 according to the folding state (e.g., folded state, flat state) of the foldable electronic device 700.

[0147] For example, when the second tuning value 622 (e.g., high-band tuning value) has been applied to the speaker, the response characteristics in the high-frequency band within the entire frequency band (e.g., 20 Hz to 20 kHz) of the output frequency can be improved, and the mid / low-frequency band output characteristics can be reduced. The speaker having the second tuning value 622 (e.g., high-band tuning value) applied thereto outputs a sound substantially in the high-frequency band within the entire frequency band (e.g., 20 Hz to 20 kHz) of the output frequency, but the mid / low-frequency band output is not completely tuned out.

[0148] For example, when the third tuning value 624 (e.g., the mid / low frequency band tuning value) is applied to the speaker, the response characteristics in the mid / low frequency band within the entire frequency band (e.g., 20 Hz to 20 kHz) of the output frequency can be improved, and the high frequency band output characteristics can be reduced. The speaker having the third tuning value 624 (e.g., the mid / low frequency band tuning value) applied thereto outputs a sound substantially in the mid / low frequency band within the entire frequency band (e.g., 20 Hz to 20 kHz) of the output frequency, but the high frequency band output is not completely tuned out.

[0149] Fig. 9 The frequency response characteristics and stereo output of the speaker of the foldable electronic device according to the embodiment of the present disclosure are shown. Fig.10 1000 is a graph showing frequency response characteristics and stereo output of controlling a speaker in a first state (eg, a flat state) of a foldable electronic device according to an embodiment of the present disclosure.

[0150] refer to Figure 6 , Fig. 9 and Fig.10 In an embodiment, a sensor module (e.g., Figure 2 The sensor module 270 in the embodiment may sense the folding angle of the foldable electronic device 700. The sensor module 270 may generate sensing data according to the folding angle of the foldable electronic device 700 and may provide the sensing data to the processor 220. The processor (e.g., Figure 1 The processor 120, Figure 2The processor 220 in the embodiment may determine the folding state (e.g., folded state, flat state) of the foldable electronic device 700 based on the sensing data input from the sensor module 270. For example, the processor 220 may determine the folding state (e.g., folded state, flat state) of the foldable electronic device 700 based on the sensing data input from the sensor module 270. Figure 2 The foldable electronic device 700 may be configured to determine whether it is in a first state (eg, a flat state) or a second state (eg, a folded state) based on sensing data input by a sensor module 270 in the foldable electronic device.

[0151] For example, the processor 220 may be based on the data from the sensor module (e.g., Figure 2 The foldable electronic device 700 may be configured to determine whether it is in a third state (eg, an intermediate state between the flat state and the folded state) based on sensing data input by the sensor module 270 in the foldable electronic device.

[0152] For example, the processor 220 may be based on the data from the sensor module (e.g., Figure 2 The foldable electronic device 700 may determine whether it is transitioning from a first state (eg, a flat state) to a second state (eg, a folded state) based on sensing data input by a sensor module 270 in the foldable electronic device.

[0153] For example, the processor 220 may be based on the data from the sensor module (e.g., Figure 2 The foldable electronic device 700 may determine whether it is transitioning from the second state (eg, the folded state) to the first state (eg, the flat state) based on sensing data input by the sensor module 270 in the foldable electronic device.

[0154] In an embodiment, when the foldable electronic device 700 is in a first state (eg, a flat state), the processor 220 may control the audio DSP (eg, Figure 2 The audio DSP 240 in the example embodiment of the present invention makes the frequency characteristics of the first to fourth speakers 740, 750, 760 and 770 output the entire output frequency band.

[0155] In an embodiment, when the foldable electronic device 700 is in a first state (eg, a flat state), the audio DSP 240 may apply the first tuning value 610 to the first speaker 740 based on the control of the processor 220 so that the first speaker 740 disposed in the first housing (eg, Figure 7 and Figure 8 The first speaker 740 in the first housing 710 in the first part 701 (eg, the first housing 710 in the first part 701) has the first sound output characteristic 601. For example, the audio DSP 240 may apply the first tuning value 610 to the first part 701 (eg, the first housing 710 in the first part 701) based on the control of the processor 220. Figure 7 and Figure 8For example, when the foldable electronic device 700 is in the first state (e.g., a flat state), the audio DSP 240 may be applied based on the control of the processor 220 so that the first speaker 740 disposed in the first housing 710 outputs a sound wave corresponding to the left channel of the stereo. Therefore, when the foldable electronic device 700 is in the first state (e.g., a flat state), the first speaker 740 disposed in the first housing (e.g., Figure 7 and Figure 8 The first speaker 740 in the first housing 710 in the embodiment of the present invention may output a sound wave having the first sound output characteristic 601. The first speaker 740 applying the first sound output characteristic 601 following the first tuning value 610 may output the entire output frequency band and may output a sound wave corresponding to the left channel.

[0156] For example, when the foldable electronic device 700 is in a first state (e.g., a flat state), the audio DSP 240 may apply the first tuning value 610 to the second speaker 750 based on the control of the processor 220, so that the second speaker 750 disposed in the first housing has the first sound output characteristic 601. Figure 7 and Figure 8 701). For example, when the foldable electronic device 700 is in the first state (e.g., a flat state), the audio DSP 240 may be applied based on the control of the processor 220 so that the second speaker 750 disposed in the first housing 710 outputs a sound wave corresponding to the left channel of the stereo. Therefore, when the foldable electronic device 700 is in the first state (e.g., a flat state), the second speaker 750 disposed in the first housing 710 may output a sound wave having the first sound output characteristic 601. The second speaker 750 applying the first sound output characteristic 601 following the first tuning value 610 may output the entire output frequency band, and may output a sound wave corresponding to the left channel.

[0157] For example, when the foldable electronic device 700 is in a first state (e.g., a flat state), the audio DSP 240 may apply the first tuning value 610 to the third speaker 760 based on the control of the processor 220, so that the third speaker 760 disposed in the second housing 720 has the first sound output characteristic 601. For example, the audio DSP 240 may apply the first tuning value 610 to the third speaker 760 disposed in the second portion 702 (e.g., Figure 7 and Figure 82. The third speaker 760 on the second part 702 in the foldable electronic device 700 is provided. For example, when the foldable electronic device 700 is in the first state (e.g., the flat state), the audio DSP 240 may be applied based on the control of the processor 220 so that the third speaker 760 provided in the second housing 720 outputs a sound wave corresponding to the right channel of the stereo. Therefore, when the foldable electronic device 700 is in the first state (e.g., the flat state), the third speaker 760 provided in the second housing 720 may output a sound wave having the first sound output characteristic 601. The third speaker 760 applying the first sound output characteristic 601 following the first tuning value 610 may output the entire output frequency band, and may output a sound wave corresponding to the right channel.

[0158] For example, when the foldable electronic device 700 is in a first state (e.g., a flat state), the audio DSP 240 may apply the first tuning value 610 to the fourth speaker 770 based on the control of the processor 220, so that the fourth speaker 770 disposed in the second housing 720 has the first sound output characteristic 601. For example, the audio DSP 240 may apply the first tuning value 610 to the fourth speaker 770 disposed in the second portion 702 (e.g., Figure 7 and Figure 8 2. The fourth speaker 770 on the second part 702 in the foldable electronic device 700 is configured to output a sound wave corresponding to the right channel of the stereo sound. For example, when the foldable electronic device 700 is in the first state (e.g., the flat state), the audio DSP 240 may be applied based on the control of the processor 220 so that the fourth speaker 770 disposed in the second housing 720 outputs a sound wave corresponding to the right channel of the stereo sound. Therefore, when the foldable electronic device 700 is in the first state (e.g., the flat state), the fourth speaker 770 disposed in the second housing 720 may output a sound wave having the first sound output characteristic 601. The fourth speaker 770 applying the first sound output characteristic 601 following the first tuning value 610 may output the entire output frequency band, and may output a sound wave corresponding to the right channel.

[0159] When the foldable electronic device 700 according to an embodiment of the present disclosure is in a first state (e.g., a flat state), the foldable electronic device 700 according to an embodiment of the present disclosure may apply a first tuning value 610 to a plurality of speakers 740, 750, 760, and 770. A first sound output characteristic 601 following the first tuning value 610 may be applied to the plurality of speakers 740, 750, 760, and 770. When the plurality of speakers 740, 750, 760, and 770 outputs the entire output frequency band and outputs a stereo sound wave, the foldable electronic device 700 may ensure a flat frequency characteristic in the entire output frequency band.

[0160] Fig.111100 is a graph showing frequency response characteristics and stereo output of a speaker controlled in a second state (eg, a folded state) of the foldable electronic device according to an embodiment of the present disclosure.

[0161] refer to Figure 6 , Fig. 9 and Fig.11 In an embodiment, a sensor module (e.g., Figure 2 The sensor module 270 in the embodiment may sense the folding angle of the foldable electronic device 700. The sensor module 270 may generate sensing data according to the folding angle of the foldable electronic device 700, and may provide the sensing data to the processor 220. The processor (e.g., Figure 1 The processor 120, Figure 2 The processor 220 in the embodiment may determine a folding state (eg, a folded state, a flat state) of the foldable electronic device 700 based on sensing data input from the sensor module 270.

[0162] For example, the processor 220 may be based on the data from the sensor module (e.g., Figure 2 The foldable electronic device 700 may be configured to determine whether it is in a first state (eg, a flat state) or a second state (eg, a folded state) based on sensing data input by a sensor module 270 in the foldable electronic device.

[0163] For example, the processor 220 may be based on the data from the sensor module (e.g., Figure 2 The foldable electronic device 700 may be configured to determine whether it is in a third state (eg, an intermediate state between the flat state and the folded state) based on sensing data input by the sensor module 270 in the foldable electronic device.

[0164] For example, the processor 220 may be based on the data from the sensor module (e.g., Figure 2 The foldable electronic device 700 may determine whether it is transitioning from a first state (eg, a flat state) to a second state (eg, a folded state) based on sensing data input by a sensor module 270 in the foldable electronic device.

[0165] For example, the processor 220 may be based on the data from the sensor module (e.g., Figure 2 The foldable electronic device 700 may determine whether it is transitioning from the second state (eg, the folded state) to the first state (eg, the flat state) based on sensing data input by the sensor module 270 in the foldable electronic device.

[0166] In an embodiment, when the foldable electronic device 700 is in the second state (eg, the folded state), the processor 220 may control the audio DSP (eg, Figure 2The audio DSP 240 in the speaker) makes the frequency characteristics of the first to fourth speakers 740, 750, 760 and 770 output sounds in substantially the high frequency band and / or the middle / low frequency band among the entire output frequency band.

[0167] In an embodiment, when the foldable electronic device 700 is in the second state (eg, the folded state), the audio DSP 240 may apply the changed tuning value 620 to the first speaker 740 based on the control of the processor 220, so that the first speaker 740 disposed in the first housing (eg, Figure 7 and Figure 8 The first speaker 740 in the first housing 710 in the first area 703 (for example, the first housing 710 in the second area 703) has the second sound output characteristic 602. For example, based on the control of the processor 220, the audio DSP 240 can apply the second tuning value 622 (for example, the high frequency band tuning value) among the changed tuning values ​​620 to the first area 703 (for example, the first housing 710 in the second area 703). Figure 8 703 in the first area 703). For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 can be applied based on the control of the processor 220 so that the first speaker 740 set in the first housing 710 outputs a sound wave corresponding to the right channel of the stereo. For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 can be applied based on the control of the processor 220 so that the first speaker 740 set in the first area 703 outputs a sound wave corresponding to the right channel of the stereo. Therefore, when the foldable electronic device 700 is in the second state (e.g., the folded state), the first speaker 740 set in the first area 703 can output a sound wave having the second sound output characteristic 602. The first speaker 740 applying the second sound output characteristic 602 following the changed tuning value 622 (eg, high frequency band tuning value) among the tuning values ​​620 may output sound in a high frequency band among the output frequency bands and may output a sound wave corresponding to the right channel.

[0168] For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may apply the changed tuning value 620 to the second speaker 750 based on the control of the processor 220, so that the second speaker 750 disposed in the first housing 710 has the second sound output characteristic 602. For example, based on the control of the processor 220, the audio DSP 240 may apply the second tuning value 622 (e.g., the high frequency band tuning value) among the changed tuning values ​​620 to the second area 704 (e.g., the second area 704). Figure 7 and Figure 8704). For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the second speaker 750 disposed in the first housing 710 outputs a sound wave corresponding to the left channel of the stereo. For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the second speaker 750 disposed in the second area 704 outputs a sound wave corresponding to the left channel of the stereo. Therefore, when the foldable electronic device 700 is in the second state (e.g., the folded state), the second speaker 750 disposed in the second area 704 may output a sound wave having the second sound output characteristic 602. The second speaker 750 applying the second sound output characteristic 602 following the changed tuning value 622 (eg, high frequency band tuning value) among the tuning values ​​620 may output a high frequency band among the output frequency bands and may output a sound wave corresponding to the left channel.

[0169] For example, when the foldable electronic device 700 is in the second state (eg, folded state), the audio DSP 240 may apply the changed tuning value 620 to the third speaker 760 based on the control of the processor 220 so that the third speaker 760 disposed in the second housing 720 (eg, Figure 7 and Figure 8 The third speaker 760 in the second housing 720 in the first area 703 (for example, the third speaker 760 in the second housing 720 in the second area 703) has the second sound output characteristic 602. For example, based on the control of the processor 220, the audio DSP 240 can apply the third tuning value 624 (for example, the mid / low frequency band tuning value) among the changed tuning values ​​620 to the third speaker 760 in the second housing 720 in the first area 703 (for example, the third speaker 760 in the second area 703) has the second sound output characteristic 602. Figure 8For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the third speaker 760 disposed in the second housing 720 outputs a sound wave corresponding to the right channel of the stereo. For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the third speaker 760 disposed in the first area 703 outputs a sound wave corresponding to the right channel of the stereo. Therefore, when the foldable electronic device 700 is in the second state (e.g., the folded state), the third speaker 760 disposed in the first area 703 may output a sound wave having the second sound output characteristic 602. The third speaker 760 applying the second sound output characteristic 602 of the third tuning value 624 (e.g., mid / low frequency band tuning value) among the changed tuning values ​​620 can output the mid / low frequency band among the output frequency bands, and can output sound waves corresponding to the right channel.

[0170] For example, when the foldable electronic device 700 is in the second state (eg, the folded state), the audio DSP 240 may apply the changed tuning value 620 to the fourth speaker 770 based on the control of the processor 220, so that the fourth speaker 770 disposed in the second housing 720 (eg, Figure 7 and Figure 8 The fourth speaker 770 in the second housing 720 in the second area 704 (for example, the fourth speaker 770 in the second housing 720 in the second area 704) has the second sound output characteristic 602. For example, based on the control of the processor 220, the audio DSP 240 can apply the third tuning value 624 (for example, the mid / low frequency band tuning value) among the changed tuning values ​​620 to the third speaker 770 in the second housing 720 (for example, the fourth speaker 770 in the second area 704) has the second sound output characteristic 602. Figure 7 and Figure 8For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the fourth speaker 770 disposed in the second housing 720 outputs a sound wave corresponding to the left channel of the stereo. For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the fourth speaker 770 disposed in the second area 704 outputs a sound wave corresponding to the left channel of the stereo. Therefore, when the foldable electronic device 700 is in the second state (e.g., the folded state), the fourth speaker 770 disposed in the second area 704 may output a sound wave having the second sound output characteristic 602. The fourth speaker 770 applying the second sound output characteristic 602 (e.g., mid / low frequency band tuning value) of the third tuning value 624 among the changed tuning values ​​620 can output the mid / low frequency band among the output frequency bands, and can output sound waves corresponding to the left channel.

[0171] When the foldable electronic device 700 according to an embodiment of the present disclosure is in a second state (e.g., a folded state), the changed tuning value 620 may be applied to a plurality of speakers 740, 750, 760, and 770. The second sound output characteristic 602 following the changed tuning value 620 may be applied to the plurality of speakers 740, 750, 760, and 770. Among the plurality of speakers 740, 750, 760, and 770, the first speaker 740 and the second speaker 750 may output a sound in a substantially high frequency band among the entire output frequency band, thereby outputting a stereo sound wave. Among the plurality of speakers 740, 750, 760, and 770, the third speaker 760 and the fourth speaker 770 may output a sound in a substantially middle / low frequency band among the entire output frequency band, thereby outputting a stereo sound wave.

[0172] The first speaker 740 to which the second tuning value 622 (e.g., high-frequency band tuning value) is applied can output right channel sound waves; the second speaker 750 to which the second tuning value 622 (e.g., high-frequency band tuning value) is applied can output left channel sound waves; the third speaker 760 to which the third tuning value 624 (e.g., mid / low-frequency band tuning value) is applied can output right channel sound waves; and the fourth speaker 770 to which the third tuning value 624 (e.g., mid / low-frequency band tuning value) is applied can output left channel sound waves, thereby ensuring a flat frequency characteristic in the entire output frequency band.

[0173] Fig.12 A method for operating a foldable electronic device according to an embodiment of the present disclosure according to a first state (eg, a flat state) or a second state (eg, a folded state) is illustrated.

[0174] refer to Fig.12 In operation 1210, a processor (eg, Figure 1 The processor 120, Figure 2 The processor 220 in the embodiment may determine that the foldable electronic device (eg, Figures 7 to 9 The foldable electronic device 700 in FIG. 1 is in a first state (eg, a flat state) or a second state (eg, a folded state). For example, the processor 220 may determine whether the foldable electronic device 700 in FIG. 1 is in a first state (eg, a flat state) or a second state (eg, a folded state) based on the information from the sensor module (eg, Figure 2 The foldable electronic device 700 may be configured to determine whether it is in a first state (eg, a flat state) or a second state (eg, a folded state) based on sensing data input by a sensor module 270 in the foldable electronic device.

[0175] When it is determined in operation 1210 that the foldable electronic device 700 is in the first state (eg, a flat state), operation 1220 may be performed.

[0176] In operation 1220, when the foldable electronic device 700 is in the first state (eg, a flat state), the processor 220 may control the audio DSP (eg, Figure 2 The audio DSP 240 in the first speaker to the fourth speaker (eg, Figures 7 to 9 The first to fourth speakers 740, 750, 760, and 770 in the embodiment have a first sound output characteristic (eg, Figure 6 The first sound output characteristic 601).

[0177] For example, the audio DSP 240 may, based on the control of the processor 220, set the first tuning value (eg, Figure 6 The first tuning value 610 in the first housing (eg, Figure 7 and Figure 8 The first speaker 740 in the first housing 710 in the first part (eg, the first housing 710 in the first part) has the first sound output characteristic 601. For example, the audio DSP 240 may apply the first tuning value 610 to the first part (eg, the first housing 710 in the first part) based on the control of the processor 220. Figure 7 The first speaker 740 on the first part 701 in the image processing apparatus 100 is provided. The first speaker 740 to which the first tuning value 610 is applied can output a sound wave having a first sound output characteristic 601.

[0178] For example, the audio DSP 240 may apply the first tuning value 610 to the second speaker 750 based on the control of the processor 220, so that the second speaker 750 disposed in the first housing 710 has the first sound output characteristic 601. For example, the audio DSP 240 may apply the first tuning value 610 to the second speaker 750 disposed on the first portion 701 based on the control of the processor 220. The second speaker 750 to which the first tuning value 610 is applied may output a sound wave having the first sound output characteristic 601.

[0179] For example, the audio DSP 240 may apply the first tuning value 610 to the third speaker 760 based on the control of the processor 220 so that the third speaker 760 disposed in the second housing (eg, Figure 7 and Figure 8 The third speaker 760 in the second housing 720 in the second part (eg, the third speaker 760 in the second part) has the first sound output characteristic 601. For example, the audio DSP 240 may apply the first tuning value 610 to the audio signal output signal set in the second part (eg, the third speaker 760 in the second part) based on the control of the processor 220. Figure 7 The third speaker 760 on the second part 702 in the embodiment of the present invention can output a sound wave having the first sound output characteristic 601 by applying the first tuning value 610 to the third speaker 760.

[0180] For example, the audio DSP 240 may apply the first tuning value 610 to the fourth speaker 770 based on the control of the processor 220, so that the fourth speaker 770 disposed in the second housing 720 has the first sound output characteristic 601. For example, the audio DSP 240 may apply the first tuning value 610 to the fourth speaker 770 disposed on the second portion 702 based on the control of the processor 220. The fourth speaker 770 to which the first tuning value 610 is applied may output a sound wave having the first sound output characteristic 601.

[0181] In operation 1230, when the foldable electronic device 700 is in a first state (e.g., a flat state), the processor 220 may control the audio DSP 240 so that the first to fourth speakers 740, 750, 760, and 770 are assigned a stereo output direction (e.g., left or right) (e.g., a stereo channel).

[0182] For example, when the foldable electronic device 700 is in a first state (eg, a flat state), the audio DSP 240 may be applied based on the control of the processor 220 so that the audio signal set in the first area (eg, Figure 7 and Figure 8The first speaker 740 in the first area 703 in the figure outputs a sound wave corresponding to the left channel of the stereo. Therefore, the first speaker 740 applying the first sound output characteristic 601 following the first tuning value 610 can output the entire output frequency band and can output a sound wave corresponding to the left channel.

[0183] For example, when the foldable electronic device 700 is in a first state (eg, a flat state), the audio DSP 240 may be applied based on the control of the processor 220 so that the audio signal set in the second area (eg, Figure 7 and Figure 8 The second speaker 750 in the second area 704 in the stereo outputs a sound wave corresponding to the left channel. Therefore, the second speaker 750 applying the first sound output characteristic 601 following the first tuning value 610 can output the entire output frequency band and can output a sound wave corresponding to the left channel.

[0184] For example, when the foldable electronic device 700 is in the first state (e.g., a flat state), the audio DSP 240 may be applied based on the control of the processor 220 so that the third speaker 760 disposed in the first area 703 outputs a sound wave corresponding to the right channel of the stereo. Therefore, the third speaker 760 applying the first sound output characteristic 601 following the first tuning value 610 may output the entire output frequency band and may output a sound wave corresponding to the right channel.

[0185] For example, when the foldable electronic device 700 is in the first state (e.g., a flat state), the audio DSP 240 may be applied based on the control of the processor 220 so that the fourth speaker 770 disposed in the second area 704 outputs a sound wave corresponding to the right channel of the stereo. Therefore, the fourth speaker 770 applying the first sound output characteristic 601 following the first tuning value 610 may output the entire output frequency band and may output a sound wave corresponding to the right channel.

[0186] For example, operation 1220 and operation 1230 may be performed consecutively, or may be performed simultaneously.

[0187] When the foldable electronic device 700 according to an embodiment of the present disclosure is in a first state (e.g., a flat state), the foldable electronic device 700 according to an embodiment of the present disclosure may apply a first tuning value 610 to a plurality of speakers 740, 750, 760, and 770. A first sound output characteristic 601 following the first tuning value 610 may be applied to the plurality of speakers 740, 750, 760, and 770. When the plurality of speakers 740, 750, 760, and 770 outputs the entire output frequency band and outputs a stereo sound wave, the foldable electronic device 700 may ensure a flat frequency characteristic in the entire output frequency band.

[0188] When it is determined in operation 1210 that the foldable electronic device 700 is in the second state (eg, a folded state), operation 1240 may be performed.

[0189] In operation 1240, when the foldable electronic device 700 is in the second state (eg, the folded state), the processor 220 may control the audio DSP (eg, Figure 2 The audio DSP 240 in the embodiment of the present invention is used to make the first to fourth speakers 740, 750, 760 and 770 have the second sound output characteristics (for example, Figure 6 For example, when the foldable electronic device 700 is in the second state (eg, the folded state), the processor 220 may control the audio DSP (eg, Figure 2 The audio DSP 240 in the audio DSP 240) causes some of the first to fourth speakers 740, 750, 760 and 770 to output sound waves substantially in the high frequency band, and some of the remaining speakers to output sound waves substantially in the middle / low frequency band.

[0190] For example, when the foldable electronic device 700 is in the second state (eg, the folded state), the audio DSP 240 may, based on the control of the processor 220, change the tuning value (eg, Figure 6 620) is applied to the first speaker 740, so that the first speaker 740 disposed on the first part 701 has the second sound output characteristic 602. For example, the audio DSP 240 may apply the second tuning value (e.g., Figure 6 The second tuning value 622 in (eg, a high frequency band tuning value) is applied to a first speaker 740 disposed on the first portion 701.

[0191] For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may apply the changed tuning value 620 to the second speaker 750 based on the control of the processor 220, so that the second speaker 750 disposed on the first part 701 has the second sound output characteristic 602. For example, the audio DSP 240 may apply the second tuning value 622 (e.g., the high frequency band tuning value) among the changed tuning values ​​620 to the first speaker 740 disposed on the first part 701 based on the control of the processor 220.

[0192] For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may apply the changed tuning value 620 to the third speaker 760 based on the control of the processor 220, so that the third speaker 760 disposed on the second portion 702 has the second sound output characteristic 602. For example, the audio DSP 240 may apply the third tuning value 624 (e.g., the mid / low frequency band tuning value) among the changed tuning values ​​620 to the third speaker 760 disposed on the second portion 702 based on the control of the processor 220.

[0193] For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may apply the changed tuning value 620 to the fourth speaker 770 based on the control of the processor 220, so that the fourth speaker 770 disposed on the second portion 702 has the second sound output characteristic 602. For example, the audio DSP 240 may apply the third tuning value 624 (e.g., the mid / low frequency band tuning value) among the changed tuning values ​​620 to the fourth speaker 770 disposed on the second portion 702 based on the control of the processor 220.

[0194] In operation 1250, when the foldable electronic device 700 is in the second state (e.g., the folded state), the processor 220 can control the audio DSP 240 so that the first to fourth speakers 740, 750, 760 and 770 are assigned a stereo output direction (e.g., a left channel or a right channel) (e.g., a stereo channel).

[0195] For example, when the foldable electronic device 700 is in the second state (eg, folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the audio signal set in the first area (eg, Figure 8 The first speaker 740 in the first area 703 in the stereo outputs a sound wave corresponding to the right channel of the stereo. Therefore, the second tuning value (eg, Figure 6 The first speaker 740 having a second tuning value 622 in (eg, a high-band tuning value) may output sound in a high-frequency band among the entire output frequency band, and may output a sound wave corresponding to a right channel.

[0196] For example, when the foldable electronic device 700 is in the second state (eg, the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the audio signal set in the second area (eg, Figure 8The second speaker 750 in the second area 704 in the stereo outputs a sound wave corresponding to the left channel of the stereo. Therefore, the second speaker 750 to which the second tuning value 622 (e.g., the high-frequency band tuning value) among the changed tuning values ​​620 is applied can output the sound in the high-frequency band among the entire output frequency band, and can output the sound wave corresponding to the left channel.

[0197] For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the third speaker 760 disposed in the first area 703 outputs a sound wave corresponding to the right channel of the stereo. Therefore, the third speaker 760 to which the third tuning value 624 (e.g., the middle / low frequency band tuning value) among the changed tuning values ​​620 is applied may output a sound in the middle / low frequency band among the entire output frequency band, and may output a sound wave corresponding to the right channel.

[0198] For example, when the foldable electronic device 700 is in the second state (e.g., the folded state), the audio DSP 240 may be applied based on the control of the processor 220 so that the fourth speaker 770 disposed in the second area 704 outputs a sound wave corresponding to the left channel of the stereo. Therefore, the fourth speaker 770 to which the third tuning value 624 (e.g., the middle / low frequency band tuning value) among the changed tuning values ​​620 is applied may output a sound in the middle / low frequency band among the entire output frequency band, and may output a sound wave corresponding to the left channel.

[0199] For example, operation 1240 and operation 1250 may be performed consecutively, or may be performed simultaneously.

[0200] In an embodiment, the first tuning value 610 and the changed tuning value 620 applied to the first speaker 740, the second speaker 750, the third speaker 760, and the fourth speaker 770 may include MB-DRC configuration values ​​(e.g., parameter values) as listed in Table 1. In an embodiment, based on a processor (e.g., Figure 2 The processor 220 in the control, audio DSP (e.g., Figure 2 The audio DSP 240 in the DSP may adjust MB-DRC parameter values ​​(eg, band frequency, band gain, limiter) to configure the first tuning value 610, the second tuning value 622, and the third tuning value 624.

[0204] In an embodiment, the first tuning value 610 and the changed tuning value 620 applied to the first speaker 740, the second speaker 750, the third speaker 760, and the fourth speaker 770 may include the OB-DRC configuration values ​​(e.g., parameter values) listed in Table 2. In an embodiment, based on a processor (e.g., Figure 2 The processor 220 in the control, audio DSP (e.g., Figure 2 The audio DSP in the OB-DRC may adjust OB-DRC parameter values ​​(eg, gain, limiter) to configure the first tuning value 610, the second tuning value 622, and the third tuning value 624.

[0207] In an embodiment, the first tuning value 610 and the changed tuning value 620 applied to the first speaker 740, the second speaker 750, the third speaker 760, and the fourth speaker 770 may include AM filter configuration values ​​(e.g., parameter values) as listed in Table 3. In an embodiment, based on a processor (e.g., Figure 2 The processor 220 in the control, audio DSP (e.g., Figure 2 The audio DSP 240 in the example embodiment may adjust AM filter parameter values ​​(eg, filter, center frequency, frequency bandwidth, gain) to configure the first tuning value 610, the second tuning value 622, and the third tuning value 624.

[0210]

[0211] When the foldable electronic device 700 according to an embodiment of the present disclosure is in a second state (e.g., a folded state), the foldable electronic device 700 according to an embodiment of the present disclosure may apply the changed tuning value 620 to the plurality of speakers 740, 750, 760, and 770. The second sound output characteristic 602 following the changed tuning value 620 may be applied to the plurality of speakers 740, 750, 760, and 770. Among the plurality of speakers 740, 750, 760, and 770, the second tuning value 622 may be applied to the first speaker 740 and the second speaker 750, thereby outputting a sound of a substantially high frequency band among the entire output frequency band, and outputting a stereo sound wave. Among the plurality of speakers 740, 750, 760, and 770, the third tuning value 624 may be applied to the third speaker 760 and the fourth speaker 770, thereby outputting a sound in a substantially middle / low frequency band among the entire output frequency band, and outputting a stereo sound wave. The plurality of speakers 740 , 750 , 760 , and 770 have the second sound output characteristics 602 , and output sound waves in the high frequency band and the middle / low frequency band, thereby ensuring a flat frequency characteristic in the entire output frequency band.

[0212] Can be omitted Fig.12 At least some of the operations shown in Fig.12 At least some of the operations shown in FIG. 1 are added before or after and / or inserted into at least some of the operations mentioned with reference to other figures in this document. Fig.12 The operations shown in can be performed by a processor (e.g., Figure 1 The processor 120, Figure 2 For example, a memory of the electronic device (e.g., Figure 1 The memory 130, Figure 2 The memory 230 in the processor 220 may store Fig.12 Instructions for at least some of the operations shown in .

[0213] Fig.13 It is shown that tuning values ​​of a plurality of speakers are applied to control the overall sound output according to a first state (eg, a flat state) or a second state (eg, a folded state) of a foldable electronic device according to an embodiment of the present disclosure.

[0214] refer to Fig.10 , Fig.11 and Fig.13 In an embodiment, when a foldable electronic device (e.g. Figure 7 and Figure 8 When the foldable electronic device 700 in the embodiment is in a first state (eg, a flat state), following the first tuning value (eg, Figure 6 The first sound output characteristic (eg, Figure 6 The first sound output characteristic 601 in FIG. 601 may be applied to the first speaker to the fourth speaker (eg, Figures 7 to 9 The first speaker 740, the second speaker 750, the third speaker 760, and the fourth speaker 770) are configured so that they have a first output level 1310 (eg, a maximum available output) (eg, a first maximum output level).

[0215] In an embodiment, when the foldable electronic device 700 is in a second state (eg, a folded state), following the second tuning value (eg, Figure 6 622) or a third tuning value (eg, Figure 6 The second sound output characteristic (eg, Figure 6 The second sound output characteristic 602 in FIG. 604 may be applied to the first speaker to the fourth speaker (eg, Figure 7 and Figure 8 The first speaker 740, the second speaker 750, the third speaker 760, and the fourth speaker 770) are configured so that they have a second output level 1320 lower than the first output level 1310 (e.g., maximum output).

[0216] When the foldable electronic device 700 is in the second state (eg, folded state), the changed tuning value (eg, Figure 6 The changed tuning value 620 in (620) is applied to the first to fourth speakers 740, 750, 760 and 770, so that the two speakers in pairs output sound waves in the high frequency band and the middle / low frequency band. If the changed tuning value 620 is applied, the output of the speaker is divided into sound waves in the high frequency band and the middle / low frequency band, and thus the overall output of the speaker can be reduced by about half (for example, by about 3dB) compared to when the first tuning value 610 is applied. Therefore, the foldable electronic device 700 becomes unable to output the maximum volume.

[0217] In an embodiment, if the user selects the first output level 1310 (eg, maximum output) as the sound output level when the foldable electronic device 700 is in the second state (eg, folded state), the processor (eg, Figure 2 The processor 220 in the embodiment may control the audio DSP (e.g., Figure 2 The audio DSP 240 in the processor 220 may apply the first tuning value 610 to the first to fourth speakers 740, 750, 760, and 770. For example, when the user selects the first output level 1310 (e.g., 80 dB or higher) as the sound output level, the audio DSP 240 may apply the first tuning value 610 to the first to fourth speakers 740, 750, 760, and 770 based on the control of the processor 220.

[0218] In an embodiment, when the foldable electronic device 700 is in the second state (e.g., the folded state), if the user selects a second output level 1320 (e.g., 79 dB or lower) that is lower than the first output level 1310 (e.g., the maximum level), the processor (e.g., Figure 2 The processor 220 in the embodiment may control the audio DSP (e.g., Figure 2 The audio DSP 240 in the processor 220 may apply the changed tuning value 620 to the first to fourth speakers 740, 750, 760, and 770. For example, when the user selects the second output level 1320 (e.g., 79 dB or lower) as the sound output level, the audio DSP 240 may apply the changed tuning value 620 to the first to fourth speakers 740, 750, 760, and 770 based on the control of the processor 220.

[0219] The foldable electronic device 700 according to an embodiment of the present disclosure may control a plurality of speakers so as to output sound at maximum output regardless of whether the foldable electronic device 700 is in a first state (eg, a flat state) or a second state (eg, a folded state).

[0220] Fig.14 Sound waves output from a plurality of speakers in a first state (eg, a flat state) of a foldable electronic device according to an embodiment of the present disclosure are shown. Fig.15 Sound waves output from a plurality of speakers in a second state (eg, a folded state) of the foldable electronic device according to an embodiment of the present disclosure are shown. Fig.16 Frequency response characteristics as a result of applying first tuning values ​​and second tuning values ​​to a plurality of speakers of a foldable electronic device according to an embodiment of the present disclosure are shown.

[0221] refer to Figures 14 to 16 According to an embodiment of the present disclosure, a foldable electronic device 1400 may include a first housing 1410 (eg, Figure 7 and Figure 8 The first shell 710 in the embodiment of the present invention), the second shell 1420 (for example, Figure 7 and Figure 8 The second housing 720 in the embodiment of the present invention and the hinge unit 1430 connecting the first housing 1410 and the second housing 1420 (for example, Figure 4 and Figure 5 , a hinge unit 430 disposed in the first housing 1410 , a first speaker 1440 disposed in the first housing 1410 , and a second speaker 1450 disposed in the second housing 1420 .

[0222] In an embodiment, when the foldable electronic device 1400 is in a first state (eg, a flat state), the audio DSP 420 may, based on the control of the processor 220, set the first tuning value 1610 (eg, Figure 6 The first tuning value 610 in is applied to the first speaker 1440 and the second speaker 1450, so that the first speaker 1440 and the second speaker 1450 have a first sound output characteristic (e.g., 1601).

[0223] For example, when the foldable electronic device 1400 is in a first state (e.g., a flat state), the first sound wave 1441 output from the first speaker 1440 and the second sound wave 1451 output from the second speaker 1450 may have the same phase. In this case, since the first sound wave 1441 and the second sound wave 1451 do not cancel each other, the audio DSP 240 may not change the phase of the first sound wave 1441 and the phase of the second sound wave 1451.

[0224] For example, when the foldable electronic device 1400 is in the second state (e.g., the folded state), the first housing 1410 and the second housing 1420 are folded to be adjacent to each other (e.g., close) relative to the hinge unit 1430, and the first speaker 1440 and the second speaker 1450 are therefore positioned to face the same direction. Therefore, the first sound wave 1441 output from the first speaker 1440 and the second sound wave 1451 output from the second speaker 1450 have a different phase (e.g., 180°) difference. For example, due to the phase difference between the sound waves 1441 and 1451 output from the first speaker 1440 and the second speaker 1450, the sound waves 1441 and 1451 can cancel each other, thereby reducing the overall sound output of the foldable electronic device 1400.

[0225] In an embodiment, according to the folding state of the foldable electronic device 1400 (eg, folded state, flat state), the processor (eg, Figure 1 The processor 120, Figure 2 The processor 220 in the embodiment may control the audio DSP (e.g., Figure 2 The audio DSP 240 in the processor 220 controls the phase of the sound waves output from the plurality of speakers 1440 and 1450. For example, the audio DSP 240 may control the phase of the sound waves from at least one of the plurality of speakers 1440 and 1450 based on the control of the processor 220.

[0226] In an embodiment, when the foldable electronic device 1400 is in the second state (eg, the folded state), the audio DSP 420 may, based on the control of the processor 220, change the tuning value 1620 (eg, Figure 6The changed tuning value 1620 in the example above is applied to the first speaker 1440 and the second speaker 1450 so that the first speaker 1440 and the second speaker 1450 have a second sound output characteristic 1602. For example, the changed tuning value 1620 may include a second tuning value (e.g., Figure 6 622) and a third tuning value (eg, Figure 6 The third tuning value 624 in .

[0227] In an embodiment, when the foldable electronic device 1400 is in the second state (e.g., the folded state), the audio DSP 240 may change the phase of the first sound wave 1441 output from the first speaker 1440 or the phase of the second sound wave 1451 output from the second speaker 1450. For example, the audio DSP 240 may change the phase of the first sound wave 1441 output from the first speaker 1440 or the phase of the second sound wave 1451 output from the second speaker 1450 so that the first sound wave 1441 and the second sound wave 1451 have the same phase. If the first sound wave 1441 and the second sound wave 1451 have the same phase, even when the foldable electronic device 1400 is in the second state (e.g., the folded state), the sound waves 1441 and 1451 from the first speaker 1440 and the second speaker 1450 do not cancel each other, thereby preventing a reduction in the sound output of the foldable electronic device 1400.

[0228] According to an embodiment of the present disclosure, a foldable electronic device 1400 and a method for operating the foldable electronic device 1400 can selectively control the phases of sound waves output from multiple speakers according to a first state (e.g., a flat state) and a second state (e.g., a folded state) of the foldable electronic device, thereby preventing a reduction in the sound output of the foldable electronic device 1400.

[0229] According to an embodiment of the present disclosure, a foldable electronic device 1400 and a method for operating the foldable electronic device 1400 can selectively apply a first tuning value 1410 and a second tuning value 1420 to multiple speakers 1440 and 1450 according to the folding state of the foldable electronic device (e.g., folded state, flat state), thereby ensuring a flat frequency characteristic in the entire output frequency band (low frequency band, mid frequency band, and high frequency band).

[0230] Fig.17 A method for configuring tuning values ​​of a plurality of speakers and phases of sound waves according to a folding angle (eg, a folded angle or an unfolded angle) of a foldable electronic device according to an embodiment of the present disclosure is shown.

[0231] refer to Fig.17 In operation 1710, a processor (eg, Figure 1 The processor 120, Figure 2 The processor 220 in the embodiment may identify a foldable electronic device (e.g., Figure 7 and Figure 8 A foldable electronic device 700, Fig.14 and Fig.15 The unfolding operation and folding operation of the foldable electronic device 1400) are described in detail.

[0232] In operation 1720, the processor 220 may determine whether the foldable electronic device 700, 1400 is in a first state (e.g., a flat state) or in a second state (e.g., a folded state). In addition, the processor 220 may determine whether the foldable electronic device 700, 1400 is in a first state (e.g., a flat state) or in a second state (e.g., a folded state).

[0233] For example, the processor 220 may be based on the data from the sensor module (e.g., Figure 2 The foldable electronic device 700, 1400 may determine whether it is in a first state (eg, a flat state) based on sensing data input by a sensor module 270 in the foldable electronic device.

[0234] For example, the processor 220 may determine whether the foldable electronic device 700 , 1400 is in the second state (eg, a folded state) based on sensing data input from the sensor module 270 .

[0235] For example, the processor 220 may determine whether the foldable electronic device 700 , 1400 is in a third state (eg, an intermediate state between the flat state and the closed state) based on sensing data input from the sensor module 270 .

[0236] For example, the processor 220 may determine whether the foldable electronic device 700 , 1400 is transitioning from a first state (eg, a flat state) to a second state (eg, a folded state) based on sensing data input from the sensor module 270 .

[0237] For example, the processor 220 may determine whether the foldable electronic device 700 , 1400 is transitioning from the second state (eg, folded state) to the first state (eg, flat state) based on sensing data input from the sensor module 270 .

[0238] For example, the processor 220 may determine an unfolding angle when the foldable electronic device 700 , 1400 is unfolded based on the sensing data input from the sensor module 270 .

[0239] For example, the processor 220 may determine a folding (eg, closing) angle when the foldable electronic device 700 , 1400 is unfolded (eg, closed) based on sensing data input from the sensor module 270 .

[0240] When it is determined in operation 1720 that the foldable electronic device 700 , 1400 is being closed from a first state (eg, a flat state) to a second state (eg, a closed state), operation 1730 may be performed.

[0241] In operation 1730, the processor 220 may determine the input signal received through the voice input device (eg, Figure 2 Whether the input volume detected by the voice input device 250 in the example is smaller than the reference volume. Figures 7 to 9 The plurality of speakers 740, 750, 760 and 770, Fig.14 and Fig.15 The sound output by the multiple speakers 1440 and 1450 in the voice input device 250 can be input to the voice input device 250, and the size of the input volume can be detected. The size of the input volume can vary according to the folding angle (e.g., unfolding angle, folding angle) of the foldable electronic device 700, 1400. The processor 220 can determine whether the foldable electronic device 700, 1400 is in a first state (e.g., a flat state) or in a second state (e.g., a closed state) based on the size of the input volume. For example, when the size of the input volume is less than a reference volume, the foldable electronic device 700, 1400 can be regarded as being in the second state (e.g., a closed state). For example, when the size of the input volume is not less than the reference volume, the foldable electronic device 700, 1400 can be regarded as being in the first state (e.g., an open state).

[0242] When it is determined in operation 1730 that the input volume is smaller than the reference volume, operation 1740 may be performed. For example, when the input volume is smaller than the reference volume, the processor 220 may determine that the foldable electronic device 700, 1400 is in the second state (e.g., a closed state).

[0243] In operation 1740, when the foldable electronic device 700, 1400 is in the second state (eg, the folded state), the processor 220 may control the audio DSP (eg, Figure 2 DSP 240 in the audio DSP 240), thereby changing the audio from the first speaker (e.g., Fig.14 and Fig.15 The first speaker 1440 and the second speaker (eg, Fig.14 and Fig.15 The phase of the sound waves of one of the second speakers 1450).

[0244] For example, the audio DSP 240 may transmit the audio from the first speaker (e.g., Fig.14 and Fig.15 The first sound wave (eg, Fig.14 and Fig.15 The phase of the first sound wave 1441 in the image is reversed by 180°. Therefore, the phase of the first sound wave 1441 and the phase of the second sound wave 1451 can become the same.

[0245] For example, the audio DSP 240 may transmit the audio from the second speaker (e.g., Fig.14 and Fig.15 The second sound wave (eg, Fig.14 and Fig.15 The phase of the second sound wave 1451 in the first sound wave 1441 is reversed by 180°. Therefore, the phase of the first sound wave 1441 and the phase of the second sound wave 1451 can become the same.

[0246] In operation 1750, sound may be output from a speaker (eg, a plurality of speakers).

[0247] In operation 1740, when the first sound wave 1441 and the second sound wave 1451 have the same phase, sound can be output from a plurality of speakers that output sound waves having the same phase. As the first sound wave 1441 and the second sound wave 1451 have the same phase, even when the foldable electronic device 700, 1400 is in the second state (e.g., the folded state), the sound output of the first speaker 1440 and the second speaker 1450 can be prevented from being reduced.

[0248] When it is determined in operation 1730 that the magnitude of the input volume is not less than the magnitude of the reference volume (eg, when the magnitude of the input volume is greater than the magnitude of the reference volume), operation 1750 may be performed.

[0249] For example, when the input volume is not less than the reference volume, the foldable electronic device 700, 1400 may not be completely in the second state (e.g., closed state), but may be unfolded at a predetermined angle. In this case, the audio DSP 240 may not change the phase of the first sound wave 1441 output from the first speaker 1440 and the phase of the second sound wave 1451 output from the second speaker 1450, and may configure a default value for them, thereby outputting the sound wave.

[0250] Returning to operation 1720 , when it is determined in operation 1720 that the foldable electronic device 700 , 1400 is unfolding from the second state (eg, closed state) to the first state (eg, flat state), operation 1760 may be performed.

[0251] In operation 1760, the processor 220 may determine the input signal received through the voice input device (eg, Figure 2 The processor 220 may determine whether the size of the input volume detected by the voice input device 250 in the foldable electronic device 700 or 1400 is greater than the size of the reference volume. For example, sounds output from multiple speakers may be input to the voice input device 250, and the size of the input volume may be detected. The size of the input volume may vary according to the folding angle (e.g., unfolded angle, folded angle) of the foldable electronic device 700 or 1400. The processor 220 may determine whether the foldable electronic device 700 or 1400 is in a first state (e.g., a flat state) or in a second state (e.g., a closed state) based on the size of the input volume.

[0252] For example, when the input volume is greater than the reference volume, the foldable electronic device 700, 1400 may be considered to be in a first state (e.g., an open state). For example, when the input volume is not greater than the reference volume, the foldable electronic device 700, 1400 may be considered to be in a second state (e.g., a closed state).

[0253] When it is determined in operation 1760 that the magnitude of the input volume is greater than the reference volume, operation 1770 may be performed.

[0254] In operation 1770, the audio DSP 240 may not change the phase of the first sound wave 1441 output from the first speaker 1440 and the phase of the second sound wave 1451 output from the second speaker 1450 and may configure default values ​​therefor, thereby outputting the sound waves accordingly.

[0255] In operation 1750, sound may be output from a speaker.

[0256] When it is determined in operation 1760 that the magnitude of the input volume is not greater than the reference volume, the audio DSP 240 may determine that the foldable electronic device 700 , 1400 is in the second state (eg, a closed state), and may perform operation 1740 .

[0257] In operation 1740 , the audio DSP 240 may invert a phase of the first sound wave 1441 or the second sound wave 1451 by 180° so that the first sound wave 1441 and the second sound wave 1451 have the same phase.

[0258] In operation 1750, the sound may be output from the speakers that output the sound waves having the same phase. When the first sound wave 1441 and the second sound wave 1451 have the same phase, even when the foldable electronic device 700, 1400 is in the second state (e.g., the folded state), the sound output of the first speaker 1440 and the second speaker 1450 may be prevented from being reduced.

[0259] Can be omitted Fig.17 At least some of the operations shown in Fig.17 At least some of the operations shown in the drawings are added before or after and / or inserted into at least some of the operations mentioned with reference to other drawings in this document. Fig.17 The operations shown in can be performed by a processor (e.g., Figure 1 The processor 120, Figure 2 For example, a memory of the electronic device (e.g., Figure 1 The memory 130, Figure 2 The memory 230 in the processor 220 may store Fig.17 Instructions for at least some of the operations shown in .

[0260] The foldable electronic device 700, 1400 according to various embodiments of the present disclosure can be implemented by using a sensor module (eg, Figure 2 An optical sensor (e.g., Figure 2 An optical sensor 272 in the foldable electronic device 700 or 1400 is used to detect a folding angle (eg, an unfolding angle or a folding angle) of the foldable electronic device 700 or 1400.

[0261] The foldable electronic device 700, 1400 according to various embodiments of the present disclosure can be implemented by using a sensor module (eg, Figure 2 A gyro sensor / accelerometer (e.g., Figure 2 A gyro sensor / acceleration sensor in the foldable electronic device 700 or 1400 is used to detect the folding angle (for example, the unfolding angle or the folding angle) of the foldable electronic device 700 or 1400.

[0262] In an embodiment, the processor 220 may determine the folding angle (e.g., unfolding angle or folding angle) of the foldable electronic device 700, 1400 based on the sensing data from the sensor module 270. Based on the detected folding angle (e.g., unfolding angle or folding angle) of the foldable electronic device 700, 1400, the processor 220 may determine whether to apply the first tuning value (e.g., Figure 6 The first tuning value 610 in Fig.16 1610), so that the plurality of speakers have a first sound output characteristic (eg, Fig.16 1601), or applying a changed tuning value (e.g., Figure 6 The changed tuning value 620, Fig.16 1620), so that the plurality of speakers have a second sound output characteristic (eg, Fig.16 The second sound output characteristic 1602 in.

[0263] For example, when the folding angle (e.g., unfolding angle or folding angle) of the foldable electronic device 700, 1400 is equal to or greater than a preconfigured reference angle (e.g., 45°), the processor 220 may determine that the foldable electronic device 700, 1400 is in a first state (e.g., a flat state). When the folding angle (e.g., unfolding angle or folding angle) of the foldable electronic device 700, 1400 is equal to or greater than a preconfigured reference angle (e.g., 45°), the audio DSP 240 may apply the first tuning value 610, 1610 to the plurality of speakers (e.g., Figure 7 and Figure 8 The first speaker 740, the second speaker 750, the third speaker 760, and the fourth speaker 770).

[0264] For example, when the folding angle (e.g., unfolding angle or folding angle) of the foldable electronic device 700, 1400 is less than a preconfigured reference angle (e.g., 45°), the processor 220 may determine that the foldable electronic device 700, 1400 is in the second state (e.g., a closed state). When the folding angle (e.g., unfolding angle or folding angle) of the foldable electronic device 700, 1400 is less than a preconfigured reference angle (e.g., 45°), the audio DSP 240 may apply the changed tuning values ​​620, 1620 to the plurality of speakers (e.g., Figure 7 and Figure 8 For example, the changed tuning values ​​620, 1620 may include a second tuning value (e.g., Figure 6 622) and a third tuning value (eg, Figure 6 The third tuning value 624 in .

[0265] Fig.18 A multi-foldable electronic device according to an embodiment of the present disclosure is shown. Fig.19 A method for configuring tuning values ​​of a plurality of speakers when a multi-foldable electronic device according to an embodiment of the present disclosure is folded once is shown. Fig. 20 A method for configuring tuning values ​​of a plurality of speakers when a multi-foldable electronic device according to an embodiment of the present disclosure is folded twice is shown.

[0266] refer to Figures 18 to 20According to an embodiment of the present disclosure, a multi-foldable electronic device 1800 may include: a shell structure, including a first shell 1810, a second shell 1820 and a third shell 1830; a display 1840, arranged in an internal space provided in the shell structure; a first speaker 1850, arranged in the first shell 1810; a second speaker 1860, arranged in the third shell 1830; a first hinge unit (not shown), configured to connect the first shell 1810 and the second shell 1820; and a second hinge unit (not shown), configured to connect the second shell 1820 and the third shell 1830.

[0267] In an embodiment, the multi-foldable electronic device 1800 can be folded so that the first part 1841 and the second part 1842 are adjacent to each other (e.g., close to each other). In an embodiment, the multi-foldable electronic device 1800 can be folded so that the second part 1842 and the third part 1843 are adjacent to each other (e.g., close to each other).

[0268] The multiply foldable electronic device 1800 may be folded such that the second portion 1842 and the third portion 1843 abut (eg, are close to) each other, and may then be folded such that the first portion 1841 and the third portion 1843 abut (eg, are close to) each other.

[0269] In an embodiment, the first speaker 1850 may output a first sound wave 1851 , and the second speaker 1860 may output a second sound wave 1861 .

[0270] For example, in the first state where the first portion 1841, the second portion 1842, and the third portion 1843 of the multi-foldable electronic device 1800 are all unfolded, the first sound wave 1851 output from the first speaker 1850 and the second sound wave 1861 output from the second speaker 1860 may have the same phase.

[0271] For example, when the multi-foldable electronic device 1800 is folded so that the second part 1842 and the third part 1843 are adjacent to (e.g., close to) each other, the first sound wave 1851 output from the first speaker 1850 and the second sound wave 1861 output from the second speaker 1860 have a phase difference of 180°, and thus the first sound wave 1851 and the second sound wave 1861 can cancel each other.

[0272] For example, an audio DSP (e.g., Figure 2 The audio DSP 240 in the example may be based on a processor (e.g., Figure 2The first sound wave 1851 or the second sound wave 1861 is changed (e.g., changed by 180°) under the control of the processor 240 in the multi-foldable electronic device 1800, so that when the second portion 1842 and the third portion 1843 of the multi-foldable electronic device 1800 are folded to be adjacent to each other (e.g., close to each other), the first sound wave 1851 and the second sound wave 1861 have the same phase. Since the first sound wave 1851 and the second sound wave 1861 have the same phase, when the multi-foldable electronic device 1800 is partially folded, the sound output of the first speaker 1850 and the second speaker 1860 can be prevented from being reduced.

[0273] In an embodiment, for example, when the second portion 1842 and the third portion 1843 of the multiply foldable electronic device 1800 are folded to be adjacent to (eg, close to) each other, the first portion 1841 and the third portion 1843 may be folded to be adjacent to (eg, close to) each other.

[0274] For example, when the first portion 1841, the second portion 1842, and the third portion 1843 of the multi-foldable electronic device 1800 are folded to overlap, the audio DSP (eg, Figure 2 The audio DSP 240 in the example may be based on a processor (e.g. Figure 2 Under the control of the processor 240 in the embodiment, a default value is configured for the phase of the first sound wave 1851 and the second sound wave 1861. When the default value is configured for the phase of the first sound wave 1851 and the second sound wave 1861, the first sound wave 1851 and the second sound wave 1861 may have the same phase.

[0275] For example, when the first portion 1841, the second portion 1842, and the third portion 1843 of the multi-foldable electronic device 1800 are folded to overlap, the audio DSP (eg, Figure 2 The audio DSP 240 in the example may be based on a processor (e.g., Figure 2 The processor 240 in the embodiment of the present invention controls the phase of the first sound wave 1851 or the phase of the second sound wave 1861 to change (for example, change by 180°) so that the first sound wave 1851 and the second sound wave 1861 have the same phase. Since the first sound wave 1851 and the second sound wave 1861 have the same phase, when the foldable electronic device 1800 is partially folded multiple times, the sound output of the first speaker 1850 and the second speaker 1860 can be prevented from being reduced.
