Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminals, and in particular to an audio playing method and an electronic device. BACKGROUND

[0002] With the development of electronic devices, more and more folding screen devices appear in the market. How to improve the user listening experience when the folding screen device plays audio is a problem that needs to be solved at present. SUMMARY

[0003] The present application provides an audio playing method and an electronic device. The method can be applied to an electronic device. The electronic device can include a folding screen, a first sound emitting device, and a first sound outlet hole. The first sound outlet hole can be located on the back of the folding screen. The first sound emitting device can emit sound through the first sound outlet hole. In the case that the folding screen is in a closed state, if the audio playing mode of the audio to be played is the earpiece mode, the electronic device can use the first sound emitting device to play the audio to be played. In this way, the user can clearly listen to the played audio through the first sound emitting device when the electronic device in the closed state is held in the earpiece playing scene.

[0004] In a first aspect, the present application provides an audio playing method. The method can be applied to an electronic device, which includes a folding screen, a first sound emitting device, and a first sound outlet hole. The first sound outlet hole is located on the back of the folding screen, and the first sound emitting device emits sound through the first sound outlet hole. The folding screen is in a closed state. The electronic device obtains a first audio to be played, which includes the audio of an instant messaging application. The electronic device uses the first sound emitting device to play the first audio to be played.

[0005] The folding screen of the electronic device can include the A screen and the B screen as shown in the present application Figure 3A The first sound emitting device can refer to the outer screen loudspeaker as shown in the present application Figure 3C The first sound outlet hole can refer to the sound outlet hole of the outer screen loudspeaker as shown in the present application Figure 3B

[0006] In the earpiece mode, the electronic device can use the first sound emitting device to play the first audio to be played.

[0007] ​It can be seen that, since the first sound outlet hole is located on the back of the folding screen, the sound emission direction of the first sound emitting device can include the direction of the back of the folding screen (for example, the opposite direction of the A-screen direction or the opposite direction of the B-screen direction in the folding screen). If the user holds the back of the folding screen (for example, the back of the A-screen or the back of the B-screen) close to the ear, the sound emission direction of the first sound emitting device can be an ear-in direction. In this way, the user can directly answer the phone by holding the electronic device with the folding screen in the closed state without unfolding the folding screen. The above method can improve the listening experience of the user when answering the phone or listening to voice messages when the folding screen is in the closed state.

[0008] In combination with the first aspect, in some embodiments, the electronic device further comprises a second sound emitting device and a second sound outlet hole, the second sound outlet hole is located on the side where the folding screen is located, and the second sound emitting device emits sound through the second sound outlet hole; after the electronic device plays the first audio using the first sound emitting device, when the folding screen changes from the closed state to the unfolded state, the electronic device plays the first audio to be played using the second sound emitting device.

[0009] The second sound emitting device can refer to the top speaker shown in the second sound emitting device Figure 2C The second sound outlet hole can refer to the sound outlet hole of the top speaker shown in the second sound emitting device Figure 2A The second sound outlet hole can be located on the top of the side where the folding screen is located.

[0010] It can be seen that, since the second sound outlet hole is located on the side where the folding screen is located, the sound emission direction of the second sound emitting device can include the direction of the folding screen (for example, the direction of the A-screen in the folding screen). If the user holds the position where the second sound outlet hole is located close to the ear, the sound emission direction of the second sound emitting device can be an ear-in direction. In this way, the user can clearly hear the call audio when holding the electronic device with the folding screen in the unfolded state to answer the phone.

[0011] In some embodiments, when the folding screen changes from the unfolded state to the closed state, the electronic device can switch the sound emitting device playing the first audio to be played to the first sound emitting device.

[0012] It can be seen that, in the earpiece mode, the electronic device can determine the sound emitting device playing the audio according to the folding screen state of the folding screen. In this way, the user can clearly hear the played audio in the earpiece playing scene when holding the electronic device in the closed state or the unfolded state. This can improve the user's experience of listening to audio using the electronic device with the folding screen in the earpiece mode.

[0013] In some embodiments, the electronic device further comprises a second sound emitting device, a third sound emitting device, a second sound outlet hole, and a third sound outlet hole. The second sound outlet hole is located on the side where the folding screen is located, and the second sound emitting device emits sound through the second sound outlet hole. The third sound outlet hole is located on the bottom frame of the electronic device, and the third sound emitting device emits sound through the third sound outlet hole. Before the electronic device obtains the first to-be-played audio, the electronic device can use the first sound emitting device, the second sound emitting device, and the third sound emitting device to play a second to-be-played audio, and the second to-be-played audio comprises a first prompt tone. The electronic device receives a first operation.

[0014] The third sound emitting device can refer to the bottom speaker shown in the present application Figure 2C The third sound outlet hole can refer to the sound outlet hole of the bottom speaker shown in the present application Figure 2A The third sound outlet hole can refer to the sound outlet hole of the bottom speaker shown in the present application

[0015] In the case where the first to-be-played audio is a call audio, the first prompt tone can be a call incoming ringtone, and the first operation can be an operation of answering the incoming call. In the case where the first to-be-played audio is a voice message audio, the first prompt tone can be a prompt tone for receiving a voice message, and the first operation can be an operation for triggering the electronic device to play the voice message (for example, an operation of clicking the voice message).

[0016] In the earphone mode, when the electronic device uses the first sound emitting device to play the first to-be-played audio, the second sound emitting device and the third sound emitting device can not need to play audio. In the earphone mode, when the electronic device uses the second sound emitting device to play the first to-be-played audio, the first sound emitting device and the third sound emitting device can not need to play audio.

[0017] It can be seen that the first prompt tone can be played in the external playing mode. Using the first sound emitting device, the second sound emitting device, and the third sound emitting device to play the first prompt tone is conducive to prompting the user that the electronic device receives a call notification or a voice message, thereby facilitating the user to answer the phone or listen to the voice message in time.

[0018] In some embodiments, the electronic device further comprises a second sound emitting device, a third sound emitting device, a second sound outlet hole, and a third sound outlet hole. The second sound outlet hole is located on the side where the folding screen is located, and the second sound emitting device emits sound through the second sound outlet hole. The third sound outlet hole is located on the bottom frame of the electronic device, and the third sound emitting device emits sound through the third sound outlet hole. After the electronic device uses the first sound emitting device to play the first to-be-played audio, the electronic device receives an operation of starting call hands-free. The electronic device obtains a third to-be-played audio, and the third to-be-played audio comprises an audio of an instant messaging application. The electronic device uses the first sound emitting device, the second sound emitting device, and the third sound emitting device to play the third to-be-played audio.

[0019] It can be seen that the user can set the audio of the instant messaging application to be played in the earphone mode or set to be played in the external mode according to needs. In the external mode, the power used by the electronic device to play the third audio to be played by using the first sound emitting device, the second sound emitting device and the third sound emitting device is greater than the power used by the electronic device to play the first audio to be played by using the first sound emitting device or the second sound emitting device in the earphone mode. In this way, in the external scene, the sound of audio playing is larger. The user can listen to the audio without needing to put the ear close to the sound emitting device.

[0020] In combination with the first aspect, in some embodiments, in a case where the folding screen is in the closed state and the audio playing mode is the external mode, the sound effect parameters of the first sound emitting device, the second sound emitting device and the third sound emitting device playing the third audio to be played are the first sound effect parameters. The first sound effect parameters can refer to the sound effect parameters 4 shown in FIG. 4. Figure 7D

[0021] When the folding screen changes from the closed state to the unfolded state, the electronic device plays the third audio to be played by using the first sound emitting device, the second sound emitting device and the third sound emitting device according to the second sound effect parameters, and the second sound effect parameters and the first sound effect parameters are different in loudness and / or equalizer (EQ) parameters. The second sound effect parameters can refer to the sound effect parameters 2 shown in FIG. 2. Figure 6D

[0022] In some embodiments, the third audio to be played includes first frequency band audio. The frequency band of the first frequency band audio is a first frequency band. For example, the first frequency band can be a low frequency band. In the first sound effect parameters, the volume of the first sound emitting device playing the first frequency band audio can be higher than the volumes of the second sound emitting device and the third sound emitting device playing the first frequency band audio. That is, in the first sound effect parameters, the volume of the first sound emitting device playing the low frequency band can be enhanced.

[0023] In some embodiments, in the second sound effect parameters, the volumes of the second sound emitting device and the third sound emitting device playing the first frequency band audio can be higher than the volume of the first sound emitting device playing the first frequency band audio. That is, in the second sound effect parameters, the volumes of the second sound emitting device and the third sound emitting device playing the low frequency band can be enhanced.

[0024] ​​It can be seen that when playing audio from instant messaging applications in speaker mode, the low-frequency audio emitted by one or more of the first, second, and third sound-emitting devices can be amplified. This achieves a better low-frequency sound effect. Furthermore, since the electronic device uses three sound-emitting devices to play the audio, the audio playback loudness is enhanced, resulting in a louder sound. Based on the aforementioned first or second sound effect parameters, the electronic device can improve the user's listening experience when playing audio from instant messaging applications in speaker mode.

[0025] In conjunction with the first aspect, in some embodiments, the electronic device further includes a second sound-emitting device, a third sound-emitting device, a second sound outlet, and a third sound outlet. The second sound outlet is located on the side where the foldable screen is located, and the second sound-emitting device emits sound through the second sound outlet. The third sound outlet is located on the bottom edge of the electronic device, and the third sound-emitting device emits sound through the third sound outlet. The electronic device acquires a fourth audio to be played, which includes audio from a media application; the electronic device uses the first, second, and third sound-emitting devices to play the fourth audio to be played.

[0026] It can be seen that the audio of media applications is usually played in speaker mode. Electronic devices can use a first sound-emitting device, a second sound-emitting device, and a third sound-emitting device to play the audio of media applications, thereby improving the playback sound effect.

[0027] When the folding screen is in the closed state, the sound effect parameters for the first, second, and third sound-emitting devices to play the fourth audio to be played are the third sound effect parameters. The third sound effect parameters can be determined based on the fourth audio to be played and the fact that the folding screen is in the closed state. The third sound effect parameters can be found in this application. Figure 8F The sound effect parameters shown are 7.

[0028] In some embodiments, when the folding screen is in the closed state, the sound sources for the first, second, and third sound-emitting devices when playing the fourth audio to be played can be the same. In the third sound effect parameters, the phases of the audio played by the first, second, and third sound-emitting devices can be the same to achieve in-phase superposition, and the volume of the low-frequency band played by the first, second, and third sound-emitting devices can all be amplified.

[0029] Based on the aforementioned third sound effect parameter, when an electronic device plays audio from a media application in the foldable screen closed state, it can achieve low-frequency enhancement and increase the loudness of the audio playback, thereby achieving a loud external speaker and good low-frequency sound effect. This can improve the user's listening experience for audio and video played externally when the foldable screen is closed.

[0030] When the folding screen changes from the closed state to the half-folded state, the electronic device plays the fourth to-be-played audio using the first sound emitting device, the second sound emitting device, and the third sound emitting device according to fourth sound effect parameters, and the fourth sound effect parameters are different from the third sound effect parameters in one or more of the phase, loudness, and EQ parameters. The fourth sound effect parameters can be determined according to the fourth to-be-played audio and the fact that the folding screen is in the half-folded state. The fourth sound effect parameters can refer to the sound effect parameters 6 shown in FIG. 6. Figure 8D The sound effect parameters 6 shown in FIG. 6.

[0031] In some embodiments, the fourth to-be-played audio can include a first audio signal, a second audio signal, and a third audio signal. The first audio signal, the second audio signal, and the third audio signal can be audio signals of different channels in the fourth to-be-played audio. In the half-folded state, the first sound emitting device can play the first audio signal. The second sound emitting device can play the second audio signal. The third sound emitting device can play the third audio signal. In the fourth sound effect parameters, the phases at which the first sound emitting device, the second sound emitting device, and the third sound emitting device play audio can be changed to change the distance at which the user hears the sound; and the volumes at which the first sound emitting device and the second sound emitting device play low-frequency bands can be enhanced, and the volume at which the third sound emitting device plays low-frequency bands can be reduced.

[0032] Based on the fourth sound effect parameters described above, the electronic device plays the audio of the media application when the folding screen is in the half-folded state, which can allow the user to identify the position of the sound heard and the position of the video image to be the same, achieve sound image centering, and achieve a sound effect of full-bodied vocals. This can improve the listening experience of the user when the folding screen is in the half-folded state.

[0033] When the folding screen changes from the closed state to the unfolded state, the electronic device plays the fourth to-be-played audio using the first sound emitting device, the second sound emitting device, and the third sound emitting device according to fifth sound effect parameters, and the fifth sound effect parameters are different from the third sound effect parameters in one or more of the phase, loudness, and EQ parameters. The fifth sound effect parameters can be determined according to the fourth to-be-played audio and the fact that the folding screen is in the unfolded state. The fifth sound effect parameters can refer to the sound effect parameters 5 shown in FIG. 5. Figure 8B The sound effect parameters 5 shown in FIG. 5.

[0034] Optionally, the electronic device can also detect the horizontal and vertical screen states of the folding screen, and play the fourth to-be-played audio using different sound effect parameters when the folding screen is in a horizontal screen state or a vertical screen state.

[0035] In some embodiments, the fourth audio to be played can include a fourth audio signal, a fifth audio signal, and a sixth audio signal. The fourth audio signal, the fifth audio signal, and the sixth audio signal can be audio signals of different channels in the fourth audio to be played. In the unfolded state, the first sound emitting device can play the fourth audio signal. The second sound emitting device can play the fifth audio signal. The third sound emitting device can play the sixth audio signal. In the fifth sound effect parameter, the phases of the audio played by the first sound emitting device, the second sound emitting device, and the third sound emitting device can be changed to change the direction from which the user hears the sound, and the EQ parameters of the audio played by the first sound emitting device, the second sound emitting device, and the third sound emitting device can also be changed.

[0036] Based on the above-mentioned fifth sound effect parameter, the electronic device plays the audio of the media application when the folding screen is in the unfolded state, which can make the user feel that the sound is coming from the actual sound emitting object in the space when listening to the audio, thereby achieving a sound effect with spatial presence and an open sound field. This can improve the listening experience of the user when playing audio-video in the unfolded state of the folding screen.

[0037] As can be seen from the above-mentioned embodiments, the electronic device can jointly determine the sound emitting device and the sound effect parameter for playing the audio according to the audio playing scene (i.e., the audio playing mode) and the folding mode. This can facilitate the user to listen to the audio in different audio playing scenes and different folding modes, and improve the user's listening experience of the audio.

[0038] In combination with the first aspect, in some embodiments, when the folding screen is in the closed state, if the audio playing mode is the earpiece mode, in addition to using the first sound emitting device to play the first audio to be played, the electronic device also uses the second sound emitting device and / or the third sound emitting device to play the first audio to be played; wherein the phase of the first audio to be played played by the second sound emitting device and / or the third sound emitting device is opposite to the phase of the first audio to be played played by the first sound emitting device.

[0039] In combination with the first aspect, in some embodiments, when the folding screen changes from the closed state to the unfolded state and the audio playing mode is the earpiece mode, in addition to using the second sound emitting device to play the first audio to be played, the electronic device also uses the first sound emitting device and / or the third sound emitting device to play the first audio to be played; wherein the phase of the first audio to be played played by the first sound emitting device and / or the third sound emitting device is opposite to the phase of the first audio to be played played by the second sound emitting device.

[0040] As can be seen, in the earpiece mode, different sound emitting devices can play audio with opposite phases, which can be cancelled by inversion to suppress the spread of sound waves to the surrounding, thereby achieving the effect of reducing sound leakage.

[0041] In a second aspect, the present application provides an audio playing method, which is applied to an electronic device. The electronic device comprises a folding screen, a first sound emitting device, a second sound emitting device, a third sound emitting device, a first sound outlet, a second sound outlet, and a third sound outlet. The first sound outlet is located on the back of the folding screen, and the first sound emitting device emits sound through the first sound outlet. The second sound outlet is located on one side of the folding screen, and the second sound emitting device emits sound through the second sound outlet. The third sound outlet is located at the bottom frame of the electronic device, and the third sound emitting device emits sound through the third sound outlet. The electronic device acquires a fourth to-be-played audio, and the fourth to-be-played audio comprises audio of a media application. The electronic device plays the fourth to-be-played audio using the first sound emitting device, the second sound emitting device, and the third sound emitting device.

[0042] It can be seen that the audio of the media application is usually played in an external playing mode. The electronic device can use the first sound emitting device, the second sound emitting device, and the third sound emitting device to play the audio of the media application, thereby improving the playing sound effect.

[0043] In combination with the second aspect, in some embodiments, when the folding screen is in a closed state, the first sound emitting device, the second sound emitting device, and the third sound emitting device play the fourth to-be-played audio with a third sound effect parameter. The third sound effect parameter can refer to the sound effect parameter 7 shown in the present application. Figure 8F

[0044] In some embodiments, when the folding screen is in a closed state, the sound source of the first sound emitting device, the second sound emitting device, and the third sound emitting device playing the fourth to-be-played audio can be the same. In the third sound effect parameter, the phases of the first sound emitting device, the second sound emitting device, and the third sound emitting device playing the audio can be the same to achieve in-phase superposition, and the volumes of the first sound emitting device, the second sound emitting device, and the third sound emitting device playing the low-frequency band can all be enhanced.

[0045] Based on the above third sound effect parameter, the electronic device plays the audio of the media application when the folding screen is in a closed state, which can achieve low-frequency enhancement and improve the loudness of audio playing, thereby achieving a large external playing loudness and a good low-frequency sound effect. This can improve the listening experience of the user playing audio and video in an external playing mode when the folding screen is in a closed state.

[0046] In combination with the second aspect, in some embodiments, when the folding screen changes from a closed state to a half-folded state, the electronic device uses the first sound emitting device, the second sound emitting device, and the third sound emitting device to play the fourth to-be-played audio according to a fourth sound effect parameter, and the fourth sound effect parameter is different from the third sound effect parameter in one or more parameters of phase, loudness, and EQ parameter. The fourth sound effect parameter can refer to the sound effect parameter 6 shown in the present application. Figure 8D

[0047] ​​In some embodiments, the fourth audio to be played can include a first audio signal, a second audio signal, and a third audio signal. The first audio signal, the second audio signal, and the third audio signal can be audio signals of different channels in the fourth audio to be played. In the half-folded state, the first sound emitting device can play the first audio signal. The second sound emitting device can play the second audio signal. The third sound emitting device can play the third audio signal. In the fourth audio effect parameter, the phases at which the first sound emitting device, the second sound emitting device, and the third sound emitting device play audio can be changed to change the distance at which the user hears the sound. In addition, the volume of the low-frequency band played by the first sound emitting device and the second sound emitting device can be enhanced, and the volume of the low-frequency band played by the third sound emitting device can be reduced.

[0048] Based on the fourth audio effect parameter described above, the electronic device plays the audio of the media application when the folding screen is in the half-folded state. This can allow the user to identify the position of the sound heard and the position of the video image, achieve sound image centering, and achieve a full-voiced sound effect. This can improve the listening experience of the user when the folding screen is in the half-folded state.

[0049] In combination with the second aspect, in some embodiments, when the folding screen changes from the closed state to the unfolded state, the electronic device uses the first sound emitting device, the second sound emitting device, and the third sound emitting device to play the fourth audio to be played according to a fifth audio effect parameter. The fifth audio effect parameter is different from the third audio effect parameter in one or more of the phase, the loudness, and the EQ parameter. The fifth audio effect parameter can refer to the audio effect parameter 5 shown in FIG. 6. Figure 8B

[0050] Optionally, the electronic device can also detect the horizontal and vertical screen state of the folding screen, and use different audio effect parameters to play the fourth audio to be played when the folding screen is in the horizontal screen state or the vertical screen state.

[0051] In some embodiments, the fourth audio to be played can include a fourth audio signal, a fifth audio signal, and a sixth audio signal. The fourth audio signal, the fifth audio signal, and the sixth audio signal can be audio signals of different channels in the fourth audio to be played. In the unfolded state, the first sound emitting device can play the fourth audio signal. The second sound emitting device can play the fifth audio signal. The third sound emitting device can play the sixth audio signal. In the fifth audio effect parameter, the phases at which the first sound emitting device, the second sound emitting device, and the third sound emitting device play audio can be changed to change the direction at which the user hears the sound. In addition, the EQ parameters at which the first sound emitting device, the second sound emitting device, and the third sound emitting device play audio can also be changed.

[0052] ​Based on the fifth sound effect parameter, the electronic device plays the audio of the media application when the folding screen is in the unfolded state, which can make the user feel that the sound is from the actual sound object in the space when listening to the audio, thereby achieving a sound effect with spatial presence and an open sound field. This can improve the listening experience of the user when playing audio-video externally when the folding screen is in the unfolded state.

[0053] From the above embodiments, it can be seen that the electronic device can jointly determine the sound emitting device and the sound effect parameter according to the audio playing scene (i.e., the audio playing mode) and the folding mode. This can facilitate the user to listen to the audio in different audio playing scenes and different folding modes, and improve the user's listening experience of the audio.

[0054] In a third aspect, the present application provides an electronic device. The electronic device can include a folding screen, a first sound emitting device, a first sound hole, a memory, and a processor. The first sound hole is located on the back of the folding screen. The first sound emitting device emits sound through the first sound hole. The memory can be used to store a computer program.

[0086] To facilitate understanding of the audio playing method of the present application, the folding screen device is introduced first.

[0087] The folding screen device can refer to an electronic device with a folding screen. The folding screen can have multiple folding modes. For example, the folding screen can be folded outward, and can also be folded inward. The folding screen folded outward can be referred to as an outer folding screen or an outer folding screen, etc. The folding screen folded inward can be referred to as an inner folding screen or an inner folding screen, etc. In some embodiments, the folding screen of the folding screen device can be folded outward, and can also be folded inward. The folding screen can include at least two screens, for example, a first screen and a second screen. The first screen can be referred to as a first display area. The second screen can be referred to as a second display area. The included angle between the first screen and the second screen changes with the folding of the folding screen. After the outer folding screen is folded, the orientation of the first screen and the orientation of the second screen are opposite. After the inner folding screen is folded, the orientation of the first screen and the orientation of the second screen are opposite. The first screen can also be referred to as A screen. The second screen can also be referred to as B screen. The folding mode of the folding screen is not limited in the embodiments of the present application.

[0088] Figure 1A An exemplary schematic diagram of the orientation of A screen and B screen in the inner folding screen is shown.

[0089] As Figure 1AAs shown in FIG. 13, the range of the angle a between the A screen and the B screen of the inner folding folding screen can be [0°, 180°]. Vector 1 is perpendicular to the A screen, and the direction of vector 1 can represent the orientation of the A screen. Vector 2 is perpendicular to the B screen, and the direction of vector 2 can represent the orientation of the B screen. Vector 1 and vector 2 can be determined by the folding screen device based on a gyroscope sensor or other modules for detecting the folding angle. The folding screen device can determine the size of the angle a according to vector 1 and vector 2.

[0090] As shown in FIG. 14, after folding, the angle a of the inner folding folding screen is 0°, and the orientation of the A screen is opposite to the orientation of the B screen.

[0091] Figure 1B As shown in FIG. 15, the orientation of the A screen and the B screen of the outer folding folding screen is exemplarily shown.

[0092] As shown in FIG. 15, the orientation of the A screen and the B screen of the outer folding folding screen is exemplarily shown. Figure 1B As shown in FIG. 15, the orientation of the A screen and the B screen of the outer folding folding screen is exemplarily shown.

[0093] As shown in FIG. 16, after folding, the angle a of the outer folding folding screen is 360°, and the orientation of the A screen is opposite to the orientation of the B screen.

[0094] The folding state of the folding screen is introduced below.

[0095] Figures 1C-1E As shown in FIG. 17, the folding screen of the electronic device 100 is in the unfolded state. The unfolded state can represent the state that the folding screen is completely unfolded. The folding screen of the electronic device 100 can include an A screen and a B screen. When the angle between the A screen and the B screen of the folding screen is 180° or approximately 180°, the folding screen of the electronic device 100 can be unfolded into a plane, and the A screen and the B screen of the folding screen are distributed on both sides of the folding edge and located on a plane. In the unfolded state, the A screen and the B screen can be displayed as a whole screen. The folding screen of the electronic device 100 can be folded along the folding edge according to the direction 11a and the direction 11b shown in FIG. 18 to form a half-folded state shown in FIG. 19.

[0096] 1, unfolded state.

[0097] As shown in FIG. 17, the folding screen of the electronic device 100 is in the unfolded state. The unfolded state can represent the state that the folding screen is completely unfolded. The folding screen of the electronic device 100 can include an A screen and a B screen. When the angle between the A screen and the B screen of the folding screen is 180° or approximately 180°, the folding screen of the electronic device 100 can be unfolded into a plane, and the A screen and the B screen of the folding screen are distributed on both sides of the folding edge and located on a plane. In the unfolded state, the A screen and the B screen can be displayed as a whole screen. The folding screen of the electronic device 100 can be folded along the folding edge according to the direction 11a and the direction 11b shown in FIG. 18 to form a half-folded state shown in FIG. 19. Figure 1C Figure 1C As shown in FIG. 18, the folding screen of the electronic device 100 is in the half-folded state. The half-folded state can represent the state that the folding screen is half-folded. The folding screen of the electronic device 100 can include an A screen and a B screen. When the angle between the A screen and the B screen of the folding screen is 90° or approximately 90°, the folding screen of the electronic device 100 can be half-folded, and the A screen and the B screen of the folding screen are distributed on both sides of the folding edge and located on a plane. In the half-folded state, the A screen and the B screen can be displayed as a whole screen. The folding screen of the electronic device 100 can be folded along the folding edge according to the direction 11a and the direction 11b shown in FIG. 18 to form a half-folded state shown in FIG. 19. Figure 1D

[0098] 2, half-folded state. ​​

[0099] As shown in Figure 1D , the folding screen of the electronic device 100 is in a half-fold state. The half-fold state can be an intermediate form between the closed state and the unfolded state. The half-fold state can also be referred to as a cradle state, a half-fold form, and the like.

[0100] In the half-fold state, the A screen and the B screen are visible to the user. The folding screen of the electronic device 100 can continue to fold along the folding edge in the direction 12a and the direction 12b as shown in Figure 1D , to form the closed state as shown in Figure 1E .

[0101] 3, the closed state.

[0102] As shown in Figure 1E , the folding screen of the electronic device 100 is in a closed state. The closed state can represent a form in which the folding screen is completely folded. The closed state can also be referred to as a folded state and the like. When the included angle between the A screen and the B screen of the folding screen is 0° or approximately 0°, the A screen and the B screen can be attached together, at which time the folding screen of the electronic device 100 is not visible to the user. In the closed state, since the folding screen of the electronic device 100 is an inner folding screen, the orientation of the A screen and the orientation of the B screen are opposite.

[0103] In some embodiments, the back of the A screen or the B screen of the folding screen in the electronic device 100 can also be provided with a display screen, which can be referred to as a third screen. For example, as shown in Figure 1E , the back of the A screen can be provided with a C screen (i.e., a third screen). The C screen can be a display screen independent of the folding screen. In the closed state, the C screen is visible to the user. Among them, the C screen is optional. In some embodiments, the electronic device 100 can also not contain the above-mentioned C screen.

[0104] In the closed state, the A screen and the B screen can rotate in directions away from each other along the folding edge. In this way, the folding screen can change from the closed state as shown in Figure 1E to the half-fold state as shown in Figure 1D , and finally to the unfolded state as shown in Figure 1C .

[0105] In some embodiments, the angle a between the A screen and the B screen can be in the range of [0°, 180°]. The angle a between the A screen and the B screen is the folding angle of the folding screen. If a is in the range of [0°, P1], the electronic device 100 can determine that the folding screen is in the closed state. If a is in the range of (P1, P2), the electronic device 100 can determine that the folding screen is in the half-folded state. If a is in the range of [P2, 180°], the electronic device 100 can determine that the folding screen is in the unfolded state. Wherein, 0° < P1 < P2 < 180°. P1 and P2 can be preset angle thresholds. P1 and P2 can be determined according to the use habits of a large number of users using the folding screen; or P1 and P2 can be set by the user in the electronic device 100.

[0106] For example, according to the use habits of most users, when the angle a between the A screen and the B screen is greater than 100°, the user is more likely to use the A screen and the B screen as a whole (i.e., as a complete display screen), and the folding screen is in the unfolded state. When the angle a between the A screen and the B screen is less than 80°, the user is more likely to use the C screen alone, and the folding screen is in the closed state.

[0107] Therefore, the value range of the preset angle threshold P1 in the embodiments of the present application can be (0, 80°], and the value range of the preset angle threshold P2 can be [100°, 180°). For example, the preset angle threshold P1 can be 75°, and the preset angle threshold P2 can be 105°. The above examples are only used to explain the present application and should not be construed as limiting.

[0108] In some embodiments, the folding screen can be a complete screen in an integrated structure. For example, the folding screen can be a flexible folding screen. The flexible folding screen includes a folding edge made of flexible material. Part or all of the flexible folding screen is made of flexible material. That is, the A screen and the B screen shown in the above Figure 1C and Figure 1D The A screen and the B screen shown in the above

[0109] In some embodiments, the folding screen can be a multi-screen folding screen, which can be composed of a plurality of independent display screens. The plurality of display screens can be connected in sequence through folding shafts. Each display screen can rotate around the folding shaft linked thereto to realize folding of the multi-screen folding screen. For example, the folding screen can include an A screen and a B screen. The electronic device 100 can independently control the A screen and the B screen.

[0110] The above Figures 1C-1EThe folding screen of the electronic device 100 folds horizontally, that is, folds along the horizontal folding edge to form two screens (screen A and screen B). In this embodiment, the folding screen can also fold vertically, that is, folds along the vertical folding edge to form two screens (left and right). This application does not limit the folding method of the folding screen of the electronic device 100. Specific details will be provided in subsequent embodiments. Figures 1C-1E The following explanation uses a horizontally folding inward screen as an example.

[0111] Figures 2A-2D An exemplary schematic diagram of a speaker of some electronic device 100 is shown.

[0112] like Figure 2A As shown, the electronic device 100 may include a top speaker and a bottom speaker. The top speaker can be located at the top of the electronic device 100. Since the electronic device 100 is an inward-folding screen, the inner screen of the electronic device 100 can be a folding screen (i.e., screen A and screen B). The inner screen side is the side where the folding screen is located. The bottom speaker can be located at the bottom of the electronic device 100. The top speaker may also be referred to as the inner screen speaker, etc. The bottom speaker may also be referred to as the lower screen speaker, etc. Both the top speaker and the bottom speaker may include a speaker array. In some embodiments, the top speaker can emit sound through a micro-slit. The bottom speaker can emit sound through an opening. This application does not limit the specific structure of the top speaker and the bottom speaker.

[0113] In some embodiments, each speaker in the electronic device 100 may be provided with a sound outlet at its corresponding position. The speakers can emit sound through these sound outlets. For example, as... Figure 2A As shown, the sound outlet of the top speaker can be formed by an opening at the top of the inner screen side, while the sound outlet of the bottom speaker can be formed by an opening on the bottom bezel of the electronic device 100. The sound outlet of the top speaker can be smaller than that of the bottom speaker. The sound emission direction of the speaker can be related to the orientation of the sound outlet. This application embodiment does not limit the structure of the sound outlet of each speaker.

[0114] The orientation of the top speaker's sound outlet can be the same as the direction of vector 2. The direction of vector 2 can be the orientation of screen A. Vector 2 is perpendicular to screen A. The orientation of the bottom speaker's sound outlet can be the same as the direction of vector 3. The direction of vector 3 can be the orientation of the bottom edge of the electronic device 100. Vector 3 can be perpendicular to vector 1. The direction of vector 1 can be the orientation of screen B. Vector 1 is perpendicular to screen B. Vector 1 and vector 2 can be referenced above. Figure 1A Introduction.

[0115] like Figure 2BAs shown, the outer screen side of the electronic device 100 is the side facing away from the inner screen side. In some embodiments, the outer screen side of the electronic device 100 may be provided with a screen 211 and a camera 212. The screen 211 may be referred to as the outer screen of the electronic device 100. The screen 211 may be as described above. Figure 1E The C-screen shown. Camera 212 may be a rear-facing camera of electronic device 100.

[0116] like Figure 2C As shown, the folding screen of the electronic device 100 includes an upper screen A and a lower screen B. The electronic device 100 can be folded along the folding edge to change the orientation of screen A (i.e., the direction of vector 1) and screen B (i.e., the direction of vector 2). The orientations of screen A and screen B can be referred to the above. Figure 1A Introduction.

[0117] The orientation of the sound outlet of the top speaker is the same as the orientation of the A-screen (it should be understood that "same orientation" can mean that the angle between the orientation of the sound outlet and the orientation of the A-screen is within a certain error range). Based on the sound outlet of the top speaker, the sound emission direction of the top speaker can include the orientation of the A-screen.

[0118] The orientation of the sound outlet of the bottom speaker (i.e., the direction of vector 3) is the same as the orientation of the bottom frame of the electronic device 100 (it should be understood that being in the same direction can include the angle between the orientation of the sound outlet and the orientation of the bottom frame being within a certain error range). Based on the sound outlet of the bottom speaker described above, the sound emission direction of the bottom speaker can include the orientation of the bottom frame of the electronic device 100.

[0119] For example, when the foldable screen is fully unfolded and placed face up on a horizontal table, the sound-emitting direction of the top speaker can include a direction upward toward the horizontal table (e.g., a direction perpendicular to the plane of the horizontal table and facing upward). The bottom speaker can emit sound in a horizontal direction (e.g., a direction parallel to the plane of the horizontal table).

[0120] In some embodiments, the top speaker can be a receiver, i.e., a handset. Audio played by the receiver needs to be brought close to the ear to be heard. The bottom speaker can be a speaker. Audio played by the speaker can be heard by the user even when the ear is not close. For example, when electronic device 100 answers a phone call or plays a voice message, electronic device 100 can play audio through the top speaker. In this case, the user needs to unfold the folded screen and bring the top speaker close to their ear to listen to the audio. When electronic device 100 makes hands-free calls or plays audio / video, electronic device 100 can play audio through the bottom speaker.

[0121] The sound direction of the top and bottom speakers is not convenient for users to answer calls or listen to voice messages when the foldable screen is closed.

[0122] As shown in Figure 2D , the electronic device 100 answers the phone or listens to the voice message when the folding screen is in the closed state, and plays the audio through the top speaker. If the user holds the side opposite to the A screen close to the ear, the sound emitting direction of the above-mentioned top speaker is towards the direction away from the user's ear, rather than the in-ear direction. And, when the folding screen is in the closed state, the A screen is attached to the B screen, and the top speaker can be blocked by the B screen. Therefore, when the folding screen is in the closed state, the sound effect of the user answering the phone or listening to the voice message through the top speaker is poor.

[0123] The present application provides an audio playing method. The method can be applied to an electronic device with a folding screen. The folding screen of the electronic device can include a first screen and a second screen. The electronic device can include at least 3 sound emitting devices: sound emitting device 1, sound emitting device 2, and sound emitting device 3.

[0124] Among them, the sound emitting device 1 can be arranged at the top of the electronic device. The sound emitting device 1 can emit sound through the sound hole arranged at the top of the inner screen side of the electronic device. The direction of the sound hole of the top of the inner screen side can be the same as the direction of the first screen (for example, the light emitting direction of the first screen). The sound emitting direction of the sound emitting device 1 includes the direction of the first screen. The sound emitting device 1 can refer to the aforementioned top speaker. The direction of the first screen can refer to the aforementioned Figure 1A The direction of the A screen as shown, that is, the direction of vector 1.

[0125] The sound emitting device 2 can be arranged at the bottom of the electronic device. The sound emitting device 2 can emit sound through the sound hole arranged at the bottom frame of the electronic device. The direction of the sound hole of the bottom frame can be the same as the direction of the bottom frame. The sound emitting direction of the sound emitting device 2 includes the direction of the bottom frame of the electronic device. The sound emitting device 2 can refer to the aforementioned bottom speaker.

[0126] The sound emitting device 3 can be arranged at the outer screen side of the electronic device. The sound emitting device 3 can emit sound through the sound hole arranged at the outer screen side of the electronic device. The direction of the sound hole of the outer screen side can be the same as the opposite direction of the first screen or the second screen. The sound emitting direction of the sound emitting device 2 includes the opposite direction of the first screen or the second screen. The opposite direction of the first screen can be the opposite direction of the aforementioned Figure 1A vector 1 as shown. The opposite direction of the second screen can be the opposite direction of the aforementioned Figure 1A vector 2 as shown.

[0127] The electronic device can determine the sound emitting device for playing audio according to an audio playing scenario and a folding state of the folding screen. The audio playing scenario can include a receiver playing scenario and a loudspeaker playing scenario. The receiver playing scenario can refer to a scenario in which a user needs to put his ear close to the sound emitting device to listen to audio. In the receiver playing scenario, the sound emitting device can play audio at power 1, and the audio playing sound is small. For example, the receiver playing scenario can include, but is not limited to, a handheld call scenario, a scenario of listening to a voice message, and the like. The loudspeaker playing scenario can refer to a scenario in which a user does not need to put his ear close to the sound emitting device to listen to audio. In the loudspeaker playing scenario, the sound emitting device can play audio at power 2, and the audio playing sound is large. Power 2 is greater than power 1. The present application does not limit the values of power 1 and power 2. For example, the loudspeaker playing scenario can include, but is not limited to, a hands-free call scenario, an audio / video (such as music, a movie, etc.) loudspeaker playing scenario, and the like. The receiver playing scenario can also be referred to as an earphone playing scenario or the like.

[0128] In some embodiments, in the receiver playing scenario, if the folding screen is in the closed state, the electronic device can play audio through the sound emitting device 3. Since the sound emitting direction of the sound emitting device 3 includes the opposite direction of the first screen orientation or the opposite direction of the second screen orientation, if the user puts the side of the first screen or the second screen away from the ear close to the ear, the sound emitting direction of the sound emitting device 3 can be an ear-in direction. This can improve the listening experience of the user when answering the phone or listening to a voice message when the folding screen is in the closed state.

[0129] In some embodiments, in the receiver playing scenario, if the folding screen is in the unfolded state, the electronic device can play audio through the sound emitting device 1. In the loudspeaker playing scenario, the electronic device can play audio through the sound emitting device 1, the sound emitting device 2 and the sound emitting device 3, to improve the audio playing sound effect.

[0130] In the receiver playing scenario, the audio playing mode of the electronic device can be referred to as a receiver mode. In the loudspeaker playing scenario, the audio playing mode of the electronic device can be referred to as a loudspeaker mode.

[0131] Figures 3A-3E Exemplary loudspeaker schematic diagrams of other electronic devices 100 are shown.

[0132] The electronic device 100 can include a sound emitting device 1, a sound emitting device 2 and a sound emitting device 3.

[0133] As shown in FIGS. 1, 2 and 3, the sound emitting device 1 can be a top loudspeaker, the sound emitting device 2 can be a bottom loudspeaker, and the sound emitting device 3 can be an outer screen loudspeaker. Figure 3A and Figure 3B As shown in FIGS. 1, 2 and 3, the sound emitting device 1 can be a top loudspeaker, the sound emitting device 2 can be a bottom loudspeaker, and the sound emitting device 3 can be an outer screen loudspeaker. The top loudspeaker and the bottom loudspeaker can refer to the aforementioned Figures 2A-2CThe external screen speaker's sound outlet can be located on the external screen side of the electronic device 100. For example, the external screen side of the electronic device 100 can be the side opposite to the folding screen. The side where the folding screens (i.e., screen A and screen B) of the electronic device 100 are located is the inner screen side. The external screen speaker's sound outlet can be located on the back of screen A or the back of screen B. Optionally, the external screen speaker's sound outlet can be located on the left or right side of the external screen side. This application embodiment does not limit the specific location of the external screen speaker's sound outlet. The external screen speaker can emit sound through its sound outlet.

[0134] The direction of the external screen speaker's sound outlet can be the same as or opposite to the direction of screen A or screen B. For example, Figure 3B As shown, the sound outlet of the external screen speaker is located on the back of screen A. The direction of the sound outlet of the external screen speaker can be the direction of vector 4. Vector 4 is perpendicular to both screen C and screen A. The direction of vector 4 is opposite to the direction of vector 1. The direction of vector 1 is the direction in which screen A is facing. It can be seen that the sound outlet of the external screen speaker faces the opposite direction to the direction in which screen A is facing, which is also the direction in which screen C is facing.

[0135] like Figure 3C As shown, the sound-emitting direction of the external screen speaker can include the direction in which screen C faces. In some embodiments, screen C can be disposed behind screen A. Therefore, the sound-emitting direction of the external screen speaker can include the opposite direction in which screen A faces, that is, opposite to the sound-emitting direction of the top speaker described above. Alternatively, screen C can be disposed behind screen B. Then the sound-emitting direction of the external screen speaker can include the opposite direction in which screen B faces. It can be seen that the top speaker can emit sound towards the inner screen side, and the external screen speaker can emit sound towards the outer screen side.

[0136] In some embodiments, the external speaker can be a receiver. The external speaker can play audio at power 1, in which case the user needs to bring the external speaker close to their ear to listen to the audio played by the external speaker.

[0137] In some embodiments, the top speaker and / or the external speaker can play audio at power 2. In this case, the user can hear the audio played by the top speaker and / or the external speaker without having to bring them close to their ear. Power 2 is greater than the power 1 mentioned above. This application embodiment does not limit the power range of the top speaker, the external speaker, and the bottom speaker during operation.

[0138] The aforementioned external speaker allows users to answer calls or listen to voice messages when the foldable screen is closed.

[0139] like Figure 3DAs shown, the electronic device 100 answers the phone or listens to the voice message when the folding screen is in the closed state, and the audio can be played through the outer screen loudspeaker. Since the sound emitting direction of the outer screen loudspeaker includes the direction in which the C screen faces, the user can place the side where the C screen is close to the ear when the folding screen is in the closed state, so that the sound emitting direction of the outer screen loudspeaker is the ear-in direction. Wherein, the user can place the position of the outer screen loudspeaker on the side where the C screen to the ear. In this way, the sound emitted by the outer screen loudspeaker can be better transmitted into the user's ear.

[0140] The above method can improve the audio listening experience of the user when the folding screen is in the closed state in the receiver playing scene by adding an outer screen loudspeaker in the electronic device 100.

[0141] In some embodiments, the sound hole of the outer screen loudspeaker can also be arranged on the edge seam of the electronic device 100. The edge seam of the electronic device 100 can refer to the side edge line of the electronic device 100, for example, the left side edge line or the right side edge line. As shown in the following figure, Figure 3E As shown, the electronic device 100 is provided with a sound hole of an outer screen loudspeaker on the side edge line of the right side close to the outer screen side. The direction of the sound hole of the outer screen loudspeaker can be the direction of vector 5. The direction of vector 5 can be between the direction of vector 4 and the direction of the right frame of the electronic device 100. For example, the direction of vector 5 and the direction of vector 4 have a preset angle (for example, 20° or 30°, etc.). Vector 4 is perpendicular to the C screen, and the direction of vector 4 is the direction of the C screen. Based on the sound hole of the outer screen loudspeaker, the sound emitting direction of the outer screen loudspeaker can include the direction of vector 5. The embodiments of the present application do not make specific limitations on the direction of vector 5.

[0142] It should be noted that the above Figures 3A-3E As shown, the positions of the top loudspeaker, the bottom loudspeaker, the outer screen loudspeaker and the corresponding sound holes are only exemplary descriptions of the present application and should not be limited to the present application.

[0143] Here, the structure of the electronic device 100 involved in the present application is introduced.

[0144] Figure 4A The hardware structure schematic diagram of the electronic device 100 is shown.

[0145] As shown, Figure 4AAs shown, the electronic device 100 can include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, a headset jack 170D, a sensor module 180, a key 190, a motor 191, an indicator 192, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc.

[0146] It can be understood that the structure shown in the embodiments of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 can include more or fewer components than shown, or combine certain components, or split certain components, or different component arrangements. The components shown can be implemented in hardware, software, or a combination of software and hardware.

[0147] The processor 110 can include one or more processing units, for example: the processor 110 can include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Among them, different processing units can be independent devices, or can be integrated in one or more processors.

[0148] Among them, the controller can be the nerve center and command center of the electronic device 100. The controller can generate operation control signals according to instruction operation codes and timing signals, and complete the control of fetching instructions and executing instructions.

[0149] The processor 110 can also be provided with a memory for storing instructions and data. In some examples, the memory in the processor 110 is a cache memory. The memory can hold instructions or data that the processor 110 has just used or is using in a loop.

In some examples, the electronic device 100 uses eSIM, i.e., embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0181] The software system of the electronic device 100 can employ a layered architecture, an event-driven architecture, a microkernel architecture, a microservices architecture, or a cloud architecture. The embodiments of the present application take a layered architecture as an example to illustrate the software structure of the electronic device 100. The system is taken as an example to illustrate the software structure of the electronic device 100.

[0182] Figure 4B The software structure diagram of the electronic device 100 of the embodiments of the present application is shown in FIG. 1.

[0183] The layered architecture divides the software into several layers, each of which has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android Runtime and system library, and the kernel layer.

[0184] The application layer can include a series of application packages.

[0185] As shown in FIG. 1, the application packages can include camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, short message, video, and the like. Figure 4B

[0186] The application framework layer provides APIs and programming frameworks for the applications of the application layer. The application framework layer includes some pre-defined functions.

[0187] As shown in FIG. 1, the application framework layer can include window manager, content provider, view system, phone manager, resource manager, notification manager, activity manager, audio management module, and the like. Figure 4B

[0188] The window manager is used to manage window programs. The window manager can obtain the size of the display screen, determine whether there is a status bar, lock the screen, and take screenshots, and the like.

[0189] The content provider is used to store and obtain data, and make the data accessible to the applications. The data can include videos, images, audios, dialed and received calls, browsing history and bookmarks, phonebook, and the like.

[0190] The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and the like. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a short message notification icon can include a view for displaying text and a view for displaying pictures.

[0191] The phone manager is used to provide the communication function of the electronic device 100. For example, the management of the call state (including call connection, call hang-up, and the like). ​​​

[0192] The resource manager provides various resources for applications, such as localized strings, icons, pictures, layout files, video files, and so on.

[0193] The notification manager enables an application to display notification information in the status bar (a pull-down notification bar), which can be used to convey a message of the notification type, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the completion of a download, a message reminder, and so on. The notification manager can also be a notification in the form of a chart or a scroll bar text appearing in the top status bar of the system, a notification of an application running in the background, or a notification in the form of a dialog window appearing on the screen. For example, a text message is prompted in the status bar, a prompt sound is emitted, the electronic device vibrates, an indicator light flashes, and so on.

[0194] The activity manager is used to manage activities (activities) and is responsible for the startup, switching, scheduling of components in the system, and the management and scheduling of applications. The activity manager can be called by the upper layer application to open the corresponding activity.

[0195] The audio management module can be used to manage the output path of the audio, and the sound effect parameters of playing the audio. In some embodiments, when an application needs to play audio, the application can send the audio to be played and the audio playing scene to the audio management module. The audio management module can obtain the folding angle of the folding screen, and determine the folding form of the folding screen according to the folding angle. Based on the audio playing scene and the folding form, the audio management module can determine which sound emitting devices (such as the top speaker, the bottom speaker, the outer screen speaker, etc.) in the electronic device 100 to play the audio. For example, if it is determined to use the top speaker to play the audio, the audio management module can transmit the audio from the application to the top speaker. If it is determined to use the top speaker, the bottom speaker, and the outer screen speaker to play the audio, the audio management module can transmit the audio from the application to the top speaker, the bottom speaker, and the outer screen speaker.

[0196] In some embodiments, under different audio playing scenes and / or different folding forms, the audio management module can determine different sound effect parameters, so that the electronic device 100 plays the audio to produce different sound effects. For example, the sound effect parameters can include but are not limited to: loudness, equalizer (EQ) parameters, etc. The EQ parameters can include frequency, gain, impact range, gain / decay mode. The above-mentioned frequency can be used to indicate the audio frequency to be adjusted. The above-mentioned gain can be used to indicate the volume increase or decrease of the audio frequency to be adjusted. The impact range can be used to indicate the frequency width of the volume change. The gain / decay mode can be used to adjust the change trend of the volume of the specified audio frequency. That is, the EQ parameters can be used to adjust the volume of the specified frequency band.

[0197] In addition to the audio to be played, the audio management module can send sound effect parameters to the sound emitting devices. Each sound emitting device can play audio according to the corresponding sound effect parameters. The sound effect parameters for different sound emitting devices to play audio can be different. The above embodiments can improve the user's audio listening experience.

[0198] The electronic device 100 can store different types of audio corresponding to sound effect parameters in different audio playing scenarios. The sound effect parameters can be preset. For example, the sound effect parameters can include sound effect parameters for playing call audio in a handheld call scenario (which can be referred to as earpiece mode parameters of call audio), sound effect parameters for playing call audio in a hands-free call scenario (which can be referred to as speakerphone mode parameters of call audio), sound effect parameters for playing audio in an audio-video speakerphone scenario (which can be referred to as sound effect parameters of audio-video), and the like. The preset sound effect parameters are not limited in the embodiments of the present application.

[0199] In some embodiments, the audio management module can perform audio signal processing on the audio to be played from the application, and then transmit the processed audio to the sound emitting device for playing the audio. For example, in an earpiece playing scenario, in order to control the leakage of the audio to the surrounding, the audio management module can adjust the phase of the audio to be played, so that the sound emitting device of the electronic device 100 plays audio with opposite phase. For another example, the audio to be played can include multiple channels. The audio management module can distinguish the multiple channels of the audio to be played, and transmit the multiple channels to different sound emitting devices respectively. The multiple sound emitting devices can play different channels of an audio, thereby generating sound effects such as stereo sound or surround sound.

[0200] In some embodiments, the audio management module can include multiple audio management modules for managing different types of audio. For example, the audio management module can include an audio management module for managing call audio playing and an audio management module for managing audio-video playing. The audio management module for managing call audio playing and the audio management module for managing audio-video playing can be independent of each other.

[0201] The Android Runtime includes a core library and a virtual machine. The Android Runtime is responsible for scheduling and management of the Android system.

[0202] The core library includes two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

[0203] The application layer and the application framework layer run in the virtual machine. The virtual machine executes the java files of the application layer and the application framework layer into binary files. The virtual machine is used to perform functions such as management of object life cycle, stack management, thread management, security and exception management, and garbage collection.

[0204] The system library can include a plurality of functional modules. For example, a surface manager, media libraries, a three-dimensional graphics processing library (e.g., OpenGL ES), a 2D graphics engine (e.g., SGL), etc.

[0205] The surface manager is used to manage a display subsystem and provides fusion of 2D and 3D layers for a plurality of applications.

[0206] The media libraries support a plurality of commonly used audio, video format playback and recording, and static image files, etc. The media libraries can support a plurality of audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0207] The three-dimensional graphics processing library is used to implement three-dimensional graphics drawing, image rendering, synthesis, and layer processing, etc.

[0208] The 2D graphics engine is a drawing engine for 2D drawing.

[0209] The kernel layer is a layer between hardware and software. The kernel layer at least includes a display driver, a camera driver, an audio driver, and a sensor driver.

[0210] Figure 5 An exemplary audio playing method provided by the present application is shown.

[0211] As shown in Figure 5 , the method can include steps S511-S514. The method can be applied to Figures 3A-3D an electronic device 100 including at least three sound emitting devices.

[0212] S511, determine an audio playing scenario, the audio playing scenario including an earpiece playing scenario and an external playing scenario.

[0213] In some embodiments, the audio playing scenario can be determined by an application in the electronic device 100 that needs to play audio. The application in the electronic device 100 that needs to play audio can include an instant messaging application and a media application. The instant messaging application can refer to an application for exchanging messages and making phone calls with other users. For example, the instant messaging application can include, but is not limited to, a call application, a social application, a short message application, etc. The audio of the instant messaging application can include call audio, voice message audio, etc. The media application can refer to an application for listening or watching multimedia content. For example, the media application can include, but is not limited to, a music application, a video application, etc. The audio of the media application can include music, movie audio, TV series audio, etc.

[0214] The audio of the instant messaging application can be set to be played in the earphone mode, or can also be set to be played in the external mode.

[0215] For example, when the call application of the electronic device 100 is making a voice call, if hands-free is not turned on, the call application can determine that the call audio is played in the earphone mode. That is, the playing scenario of the call audio is the earphone playing scenario. If hands-free is turned on, the call application can determine that the call audio is played in the external mode. That is, the playing scenario of the call audio is the external playing scenario.

[0216] The audio of the media application is usually played in the external mode.

[0217] For example, when the music application of the electronic device 100 is playing audio, if the electronic device 100 is not connected to the earphone, the music application can determine that the music is played in the external mode. That is, the playing scenario of the music is the external playing scenario. The method for determining the audio playing scenario is not limited in the embodiments of the present application.

[0218] S512, determine the folding mode of the folding screen, the folding mode including an unfolded state, a half-folded state, and a closed state.

[0219] The electronic device 100 can determine the folding mode according to the folding angle of the folding screen. The unfolded state, the half-folded state, and the closed state can refer to the foregoing descriptions.

[0220] S513, determine the sound emitting device and the sound effect parameter for playing the audio according to the audio playing scenario and the folding mode.

[0221] S514, play the audio using the determined sound emitting device and the sound effect parameter.

[0222] In some embodiments, if the audio playing scenario is the earphone playing scenario and the folding screen is in the closed state, the electronic device 100 can use the outer screen loudspeaker to play the audio. If the audio playing scenario is the earphone playing scenario and the folding screen is in the unfolded state, the electronic device 100 can use the top loudspeaker to play the audio. In the earphone playing scenario, the sound effect parameter of the outer screen loudspeaker for playing the audio can be the same as the sound effect parameter of the top loudspeaker for playing the audio. In this way, the sound effect heard by the user when the user is close to the sound emitting device (i.e., the outer screen loudspeaker) when the folding screen is in the closed state can be the same as the sound effect heard by the user when the user is close to the sound emitting device (i.e., the top loudspeaker) when the folding screen is in the unfolded state. That is, in the earphone playing scenario, the experience of the user listening to the audio in different folding modes can be consistent. This can improve the user experience of using the folding screen to play audio.

[0223] Alternatively, the sound effect parameter of the outer screen loudspeaker for playing the audio can be different from the sound effect parameter of the top loudspeaker for playing the audio.

[0224] In some embodiments, if the audio playback scenario is an external playback scenario, the electronic device 100 can use the top speaker, the bottom speaker, and the outer screen speaker to play audio. Among them, in different folding states, the sound effect parameters of the sound emitting device playing audio can be different.

[0225] For example, in the unfolded state, the top speaker, the bottom speaker, and the outer screen speaker can play audio according to the sound effect parameters provided by the audio management module to achieve a sound effect with spatial presence, open sound field. In the half-folded state, the top speaker, the bottom speaker, and the outer screen speaker can play audio according to the sound effect parameters provided by the audio management module to achieve a sound effect with centered sound image and full-bodied vocals. In the closed state, the top speaker, the bottom speaker, and the outer screen speaker can play audio according to the sound effect parameters provided by the audio management module to achieve a sound effect with loud external playback and good low frequency.

[0226] The sound effect parameters used by the sound emitting device in different audio playback scenarios and different folding states will be described in subsequent embodiments, which will not be expanded here. The sound effect parameters of the electronic device 100 in the embodiments for the multiple sound emitting devices to play audio to achieve the above sound effects are not limited.

[0227] In some embodiments, in the external playback scenario, the electronic device 100 can use one or two sound emitting devices in the top speaker, the bottom speaker, and the outer screen speaker to play audio.

[0228] From the above method, it can be seen that the electronic device 100 can jointly determine the sound emitting device and the sound effect parameters for playing audio according to the audio playback scenario and the folding state. This can facilitate the user to listen to audio in different audio playback scenarios and different folding states, and improve the user's audio listening experience.

[0229] The audio playback scenario and method of the present application will be introduced below taking the call scenario as an example. Among them, the call scenario can include a handheld call scenario and a hands-free call scenario. The handheld call scenario belongs to the above earpiece playback scenario. The hands-free call scenario belongs to the above external playback scenario.

[0230] Figure 6A An audio playback scenario of a handheld call is shown.

[0231] As Figure 6A shown, the electronic device 100 establishes a call connection with other devices, and receives call audio of the opposite end of the call connection. The electronic device 100 can display a user interface 630 on the folding screen. The user interface 630 can include a hands-free control 631. The hands-free control 631 can be used to turn on or turn off the hands-free function. When the hands-free control 631 is in the on state, the electronic device 100 can use the top speaker, the bottom speaker, and the outer screen speaker to play the call audio. When the hands-free control 631 is in the off state, the electronic device 100 can use the earpiece to play the call audio. Figure 6AAs shown in the unselected state, the hands-free function is in the closed state. That is, the current call scene is a handheld call scene.

[0232] As shown in the unselected state, the hands-free function is in the closed state. That is, the current call scene is a handheld call scene. Figure 6A As shown in the unselected state, the hands-free function is in the closed state. That is, the current call scene is a handheld call scene.

[0233] As shown in the unselected state, the hands-free function is in the closed state. That is, the current call scene is a handheld call scene. Figure 6A As shown in the unselected state, the hands-free function is in the closed state. That is, the current call scene is a handheld call scene.

[0234] In some embodiments, the electronic device 100 displays Figure 6A As shown in the unselected state, the hands-free function is in the closed state. That is, the current call scene is a handheld call scene.

[0235] When the operation of answering the incoming call is detected, the electronic device 100 can answer the call. The above-mentioned incoming call notification interface can include an answering control. The answering control can be used to answer the call. The above-mentioned operation of answering the incoming call can include an operation on the answering control, or an operation of placing the speaker (such as the top speaker or the outer screen speaker) close to the ear. Among them, the top speaker and the outer screen speaker can be provided with a distance sensor. When receiving the incoming call notification, the electronic device 100 can detect whether the user places the top speaker or the outer screen speaker close to the ear through the above-mentioned distance sensor. If the user places the top speaker or the outer screen speaker close to the ear, the electronic device 100 can answer the call.

[0236] Figure 6B An audio playing method provided by the present application is shown.

[0237] S611, in the earpiece playing scene, the folding screen is in the unfolded state.

[0238] The method for the electronic device 100 to determine the audio playing scene and the folding mode can refer to the introduction of the foregoing embodiments. For example, the earpiece playing scene can be the handheld call scene shown in the unselected state. Figure 6A

[0239] S612, using the top speaker to play the audio according to the sound effect parameter 1.

[0240] ​In some embodiments, the electronic device 100 can obtain the sound effect parameter 1 from the memory. The sound effect parameter 1 can be a sound effect parameter corresponding to the to-be-played audio in the earpiece playing scene. For example, the to-be-played audio is a call audio. The sound effect parameter 1 can be an earpiece mode parameter of the call audio. For another example, the to-be-played audio is a voice message. The sound effect parameter 1 can be an earpiece mode parameter of the voice message.

[0241] The sound effect parameter 1 can include a loudness 1, an EQ parameter 1, and the like. The application embodiments do not limit the specific values of the loudness 1 and the EQ parameter 1. The loudness 1 is usually low. In this way, the audio played by the top speaker can be less likely to be heard by a user far away from the electronic device 100.

[0242] Figure 6C An audio playing scene of a hands-free call is shown.

[0243] In the case where the hands-free function is turned off, in response to Figure 6A an operation, such as a click operation, on the hands-free control 631, the electronic device 100 can turn on the hands-free function and display Figure 6C the user interface 630.

[0244] As shown in Figure 6C , the hands-free control 631 is in a selected state. This can indicate that the hands-free function has been turned on. When the hands-free function is turned on, the call scene changes from the Figure 6A handheld call scene to the Figure 6C hands-free call scene.

[0245] As shown in Figure 6C , the folding screen of the electronic device 100 is in an unfolded state. The electronic device 100 can play the call audio using the top speaker, the bottom speaker, and the outer screen speaker.

[0246] In some embodiments, when switching from the hands-free call scene to the handheld call scene, the electronic device 100 can adjust the sound production device for playing the call audio from the top speaker, the bottom speaker, and the outer screen speaker to the top speaker, i.e., stop playing the call audio using the outer screen speaker and the bottom speaker.

[0247] As shown in Figure 6C , when the call scene switches from the handheld call scene to the hands-free call scene, the electronic device 100 can adjust the sound production device for playing the call audio from the top speaker to the top speaker, the bottom speaker, and the outer screen speaker. In the hands-free call scene, the electronic device 100 uses the above three sound production devices to enhance the playing loudness of the call audio and improve the user's call experience.

[0248] Figure 6DAn audio playing method is shown.

[0249] S621, in the hands-free call scenario, the foldable screen is in the unfolded state.

[0250] S622, using the top speaker, the bottom speaker and the outer screen speaker to play the call audio according to the sound effect parameter 2.

[0251] In some embodiments, the top speaker, the bottom speaker and the outer screen speaker can all receive the call audio. That is to say, in the hands-free call scenario, the sound sources played by the top speaker, the bottom speaker and the outer screen speaker can be the same.

[0252] The electronic device 100 can obtain the loudness 2' and the EQ parameter 2' of the call audio from the memory. The electronic device 100 can increase the weight of the sound waves emitted by the top speaker and the bottom speaker.

[0253] Specifically, the electronic device 100 can increase the volume of the low frequency band on the basis of the EQ parameter 2' to obtain the EQ parameter 2a and the EQ parameter 2b. The volume of the low frequency band in the EQ parameter 2a and the EQ parameter 2b is higher than that in the EQ parameter 2'. For example, the above-mentioned low frequency band can include audio less than 1KHz. The range of the low frequency band is not limited in the embodiments of the present application. Optionally, the EQ parameter 2a and the EQ parameter 2b can be the same.

[0254] The electronic device 100 can transmit the loudness 2' and the EQ parameter 2a to the top speaker. The top speaker can play the call audio according to the loudness 2' and the EQ parameter 2a.

[0255] The electronic device 100 can transmit the loudness 2' and the EQ parameter 2b to the bottom speaker. The bottom speaker can play the call audio according to the loudness 2' and the EQ parameter 2b.

[0256] The electronic device 100 can transmit the loudness 2' and the EQ parameter 2' to the outer screen speaker. The outer screen speaker can play the call audio according to the loudness 2' and the EQ parameter 2'.

[0257] That is to say, the sound effect parameter 2 can include the loudness 2', the EQ parameter 2', the EQ parameter 2a and the EQ parameter 2b.

[0258] Optionally, the electronic device 100 can increase the loudness based on the loudness 2' mentioned above, resulting in loudness 2a and loudness 2b. Both loudness 2a and loudness 2b are higher than loudness 2'. Loudness 2a and loudness 2b can be the same. Specifically, the top speaker can play the call audio at loudness 2a. The bottom speaker can play the call audio at loudness 2b. The external screen speaker can play the call audio at loudness 2'.

[0259] In some embodiments, Figure 6C When the foldable screen is in its unfolded state and the audio playback is in an external speaker scenario, the power of the top speaker, external screen speaker, and bottom speaker can be the same or different. If the power of the top speaker, external screen speaker, and bottom speaker is the same, then the power is greater than [a certain value]. Figure 6A The diagram shows the power of the top speaker when the foldable screen is in the unfolded state and the audio playback scenario is earpiece playback. If the audio playback power of the top speaker, external screen speaker, and bottom speaker are different, then the highest power among the top speaker, external screen speaker, and bottom speaker is greater than [the maximum power]. Figure 6A The power of the top speaker playing audio when the foldable screen is in the unfolded state and the audio playback scenario is earpiece playback scenario.

[0260] As shown by the above method, in a hands-free calling scenario, the electronic device 100 can use three sound-emitting devices to play the call audio. This enhances the loudness of the call audio playback. The three sound-emitting devices can play the call audio according to sound effect parameter 2. Since the volume of the low-frequency band played by the top and bottom speakers is enhanced in sound effect parameter 2, the low-frequency sound effect of the call audio is good. The above method can achieve a loud and good low-frequency sound effect in a hands-free calling scenario, improving the user's listening experience during hands-free calls.

[0261] It should be noted that this applies when the foldable screen is unfolded and the audio playback is via external speaker (e.g., Figure 6C In the hands-free calling scenario shown, the user typically places the electronic device 100 on a table with the folded screen facing upwards. This obstructs the external speaker from playing audio. Therefore, the electronic device 100 can amplify the volume of the low-frequency bands played by the top and bottom speakers to improve the audio playback sound quality.

[0262] In some embodiments, when the folded screen is in the unfolded state and the audio playback scenario is an external speaker scenario, the electronic device 100 can detect the placement posture of the electronic device 100. If the electronic device 100 is placed with the folded screen facing upwards, the electronic device 100 can proceed according to... Figure 6DThe sound effect parameter 2 plays audio. If the electronic device 100 is placed in the posture with the folding screen facing down, the electronic device 100 can enhance the audio played by the outer screen speaker and the bottom speaker in the low frequency band to improve the playing sound effect of the audio. It can be understood that when the electronic device 100 is placed in the posture with the folding screen facing down, the top speaker will be blocked when playing audio. The embodiments of the present application do not limit the method of detecting the placement posture of the electronic device 100 described above.

[0263] In some embodiments, in a hands-free call scenario, if the folding screen is in the unfolded state, the electronic device 100 can use one or two of the top speaker, the bottom speaker, and the outer screen speaker to play call audio. Among them, when using one of the top speaker, the bottom speaker, and the outer screen speaker to play call audio, the power of the speaker playing call audio can be higher than Figure 6A The power of the top speaker playing call audio is shown.

[0264] Figure 7A Another audio playing scene of handheld call is shown.

[0265] As Figure 7A shown, the folding screen of the electronic device 100 is in the closed state. The electronic device 100 establishes a call connection with other devices. The electronic device 100 can display a user interface 730 on the C screen. The user interface 730 can include a hands-free control 731. The hands-free control 731 can refer to the hands-free control 631 described above Figure 6A . It can be known from the scene shown above Figure 6A that the current call scenario is a handheld call scenario. Therefore, the electronic device 100 can use the outer screen speaker to play call audio. Among them, the top speaker and the bottom speaker can not need to play call audio.

[0266] In some embodiments, in a handheld call scenario, if the folding form of the folding screen changes from the unfolded state shown by Figure 6A to the closed state shown by Figure 7A , the electronic device 100 can switch the sound device for playing call audio from the top speaker to the outer screen speaker. Conversely, in a handheld call scenario, if the folding form of the folding screen changes from the closed state shown by Figure 7A to the unfolded state shown by Figure 6A , the electronic device 100 can switch the sound device for playing call audio from the outer screen speaker to the top speaker.

[0267] As Figure 7A can be known, the user can directly use the outer screen (i.e. the C screen) to answer the phone without unfolding the folding screen. The user can hold the electronic device 100 with the folding screen in the closed state, and place the position of the outer screen speaker close to the ear (refer to Figure 3DIn this way, the sound emission direction of the call audio played can be the ear-in direction, and the user can clearly listen to the call audio. The electronic device 100 can provide a good call audio listening experience for the user in the handheld call scenario regardless of whether the folding screen is in the unfolded state or the closed state.

[0268] Figure 7B An audio playing method is shown.

[0269] S711, in the earphone playing scenario, the folding screen is in the closed state.

[0270] For example, the earphone playing scenario can be Figure 7A the handheld call scenario shown.

[0271] S712, playing the audio according to the sound effect parameter 3 using the outer screen loudspeaker.

[0272] In some embodiments, the sound effect parameter 3 can be pre-stored in the memory of the electronic device 100. The sound effect parameter 3 can be the same as the sound effect parameter 1 corresponding to the to-be-played audio in the earphone playing scenario, i.e., the sound effect parameter corresponding to the to-be-played audio in the earphone playing scenario. In this way, the consistency of the user's experience of listening to the audio in different folding modes in the earphone playing scenario can be realized. Figure 6B

[0273] Alternatively, the sound effect parameter corresponding to the to-be-played audio in the earphone playing scenario when the folding screen is in the closed state can be different from the sound effect parameter corresponding to the to-be-played audio in the earphone playing scenario when the folding screen is in the unfolded state. That is, the sound effect parameter 3 can be different from the sound effect parameter 1. The sound effect parameter 3 and the sound effect parameter 1 can be stored in the memory of the electronic device 100. In the handheld call scenario, the electronic device 100 can select to use the sound effect parameter 1 or the sound effect parameter 3 according to the folding mode.

[0274] Figure 7C An audio playing scenario in the hands-free call scenario is shown.

[0275] In the case where the hands-free function is turned off, in response to Figure 7A the operation on the hands-free control 731, such as a click operation, the electronic device 100 can turn on the hands-free function, and display Figure 7C the user interface 730.

[0276] As shown in Figure 7C , the hands-free control 731 is in the selected state. This can indicate that the hands-free function has been turned on. When the hands-free function is turned on, the call scenario changes from Figure 7A the handheld call scenario to Figure 7C the hands-free call scenario.

[0277] As shown in Figure 7C ​As shown, the folding screen of the electronic device 100 is in the closed state. The electronic device 100 can play call audio using the top speaker, the bottom speaker, and the outer screen speaker.

[0278] As shown, the folding screen of the electronic device 100 is in the closed state. The electronic device 100 can play call audio using the top speaker, the bottom speaker, and the outer screen speaker. Figure 7C As shown, the folding screen of the electronic device 100 is in the closed state. The electronic device 100 can play call audio using the top speaker, the bottom speaker, and the outer screen speaker. Figure 6C As shown, the folding screen of the electronic device 100 is in the closed state. The electronic device 100 can play call audio using the top speaker, the bottom speaker, and the outer screen speaker. In this way, the loudness of the call audio can be enhanced, and the user's call experience can be improved.

[0279] Figure 7D An audio playing method provided by the present application is shown.

[0280] S721, in the hands-free call scenario, the folding screen is in the closed state.

[0281] S722, using the top speaker, the bottom speaker, and the outer screen speaker to play call audio according to the sound effect parameter 4.

[0282] The sound sources played by the top speaker, the bottom speaker, and the outer screen speaker can be the same.

[0283] In some embodiments, the electronic device 100 can obtain the loudness 4' and the EQ parameter 4' of the call audio in the closed state from the memory. The loudness 4' and the EQ parameter 4' can be different from the aforementioned Figure 6D The sound effect parameter 2' shown can be different. The sound effect parameter 2' can be the loudness and the EQ parameter of the call audio in the unfolded state. Alternatively, the sound effect parameter 4' and the sound effect parameter 2' can be the same.

[0284] The sound effect parameter 4' can include the loudness 4' and the EQ parameter 4'. The electronic device 100 can increase the weight of the sound waves emitted by the outer screen speaker.

[0285] Specifically, the electronic device 100 can increase the volume of the low-frequency band based on the EQ parameter 4' to obtain the EQ parameter 4a. That is, the volume of the low-frequency band in the EQ parameter 4a is higher than that in the EQ parameter 4'.

[0286] The electronic device 100 can transmit the loudness 4' and the EQ parameter 4' to the top speaker. The top speaker can play call audio according to the loudness 4' and the EQ parameter 4'.

[0287] The electronic device 100 can transmit the loudness 4' and the EQ parameter 4' to the bottom speaker. The bottom speaker can play call audio according to the loudness 4' and the EQ parameter 4'.

[0288] The electronic device 100 can transmit the loudness 4', the EQ parameter 4a to the outer screen loudspeaker. The outer screen loudspeaker can play the call audio according to the loudness 4', the EQ parameter 4a.

[0289] That is, the sound effect parameter 4 can include the loudness 4', the EQ parameter 4', and the EQ parameter 4a.

[0290] Optionally, the electronic device 100 can increase the loudness on the basis of the loudness 4' to obtain the loudness 4a. The loudness 4a is higher than the loudness 4'. The outer screen loudspeaker can play the call audio according to the loudness 4a.

[0291] In some embodiments, the sound effect parameter 4 can be the same as the sound effect parameter 2 shown in the foregoing Figure 6D The step S722 can refer to the step S622 shown in the foregoing Figure 6D That is, in the hands-free call scenario, the audio playing method when the folding screen is in the closed state can be the same as the audio playing method when the folding screen is in the unfolded state. The electronic device 100 can detect the audio playing scenario. If the audio playing scenario is the hands-free call scenario, the electronic device 100 can directly play the call audio according to the step S622 without detecting the folding state of the folding screen. If the audio playing scenario is the earpiece playing scenario (such as the handheld call scenario), the electronic device 100 can further detect the folding state of the folding screen. When the folding screen is in the unfolded state, the electronic device 100 can play the audio according to the step S612; when the folding screen is in the closed state, the electronic device 100 can play the audio according to the step S712.

[0292] In some embodiments, in the case where the folding screen shown in the foregoing Figure 7C is in the closed state and the audio playing scenario is the external playing scenario, the powers at which the top loudspeaker, the outer screen loudspeaker, and the bottom loudspeaker play the audio can be the same or different. If the powers at which the top loudspeaker, the outer screen loudspeaker, and the bottom loudspeaker play the audio are the same, the power is greater than the power at which the top loudspeaker plays the audio in the case where the folding screen shown in the foregoing Figure 7A is in the closed state and the audio playing scenario is the earpiece playing scenario. If the powers at which the top loudspeaker, the outer screen loudspeaker, and the bottom loudspeaker play the audio are different, the maximum power among the powers at which the top loudspeaker, the outer screen loudspeaker, and the bottom loudspeaker play the audio is greater than the power at which the top loudspeaker plays the audio in the case where the folding screen shown in the foregoing Figure 7A is in the unfolded state and the audio playing scenario is the earpiece playing scenario.

[0293] As can be known from the above method, in the hands-free call scenario, the electronic device 100 can use the three sound emitting devices to play the call audio. In this way, the playing loudness of the call audio can be enhanced. The three sound emitting devices can play the call audio according to the sound effect parameter 4. Since in the sound effect parameter 4, the volume of the low frequency band played by the outer screen loudspeaker is enhanced, the low frequency sound effect of the call audio is good. The above method can achieve a sound effect with large loudness and good low frequency in the hands-free call scenario, and improve the listening experience of the user in the hands-free call.

[0294] It needs to be noted that in the case where the folding screen is in the closed state and the audio playing scenario is the external playing scenario (for example, the hands-free call scenario) shown in FIG. 13, the user usually places the electronic device 100 on the desktop in a posture with the display screen (for example, the C screen) on the outer screen side facing upwards. When the folding screen is in the closed state, the top loudspeaker will be blocked when playing audio. Therefore, the electronic device 100 can enhance the volume of the low frequency band played by the outer screen loudspeaker to improve the playing sound effect of the audio. Figure 7C

[0295] In some embodiments, in the case where the folding screen is in the closed state and the audio playing scenario is the external playing scenario, the electronic device 100 can detect the placement posture of the electronic device 100. If the electronic device 100 is placed in a posture with the display screen on the outer screen side facing upwards, the electronic device 100 can play the audio according to the sound effect parameter 4 shown in FIG. 13. If the electronic device 100 is placed in a posture with the display screen on the outer screen side facing downwards, the electronic device 100 can enhance the audio played by the bottom loudspeaker in the low frequency band to improve the playing sound effect of the audio. It can be understood that when the electronic device 100 is placed in a posture with the display screen on the outer screen side facing downwards, the outer screen loudspeaker will be blocked when playing audio. The embodiments of the present application do not limit the method of detecting the placement posture of the electronic device 100. Figure 7D

[0296] In some embodiments, in the hands-free call scenario, if the folding screen is in the closed state, the electronic device 100 can use one or two of the top loudspeaker, the bottom loudspeaker and the outer screen loudspeaker to play the call audio. Wherein, when one of the top loudspeaker, the bottom loudspeaker and the outer screen loudspeaker is used to play the call audio, the power of the loudspeaker playing the call audio can be higher than the power of the top loudspeaker playing the call audio shown in FIG. 12. Figure 7A

[0297] In some embodiments, in the earphone playing scenario, if the folding screen is in the stand state, the electronic device 100 can use the top loudspeaker or the outer screen loudspeaker to play the audio. Wherein, the sound effect parameter used by the electronic device 100 to play the audio can be the same as the above sound effect parameter 1 or the sound effect parameter 3, or can also be different from the sound effect parameter 1 and the sound effect parameter 3.

[0298] ​​​In the hands-free call scenario, if the folding screen is in the stand state, the electronic device 100 can use the top speaker, the outer screen speaker, and the bottom speaker to play call audio. The sound effect parameters used by the electronic device 100 to play the call audio can be the same as the sound effect parameters 2 or the sound effect parameters 4 described above, or can also be different from the sound effect parameters 2 and the sound effect parameters 4.

[0299] The method of playing voice messages or other audio capable of switching audio playing modes in the earpiece mode and in the external playing mode can refer to the playing method of the call audio described above.

[0300] The audio playing scene and method of the present application will be introduced below taking the audio-video external playing scene as an example. The audio-video external playing scene can include a scene of external playing of sound when playing multimedia content such as video (such as a movie, a TV series, a short video), playing music, etc. The audio-video external playing scene belongs to the external playing scene.

[0301] Figure 8A An audio playing scene of external playing of audio-video is shown.

[0302] As shown in Figure 8A , the folding screen is in the unfolded state, and the electronic device 100 is playing a video. The electronic device 100 can display a video playing interface 810. The electronic device 100 can use the top speaker, the bottom speaker, and the outer screen speaker to play audio. The sound effect parameters of the top speaker, the bottom speaker, and the outer screen speaker when playing audio can be different. For example, the top speaker can play audio according to parameters 11. The outer screen speaker can play audio according to parameters 12. The bottom speaker can play audio according to parameters 13. The above sound effect parameters will be introduced in detail in the embodiments below, which will not be expanded here. Figure 8B

[0303] In some embodiments, the top speaker, the bottom speaker, and the outer screen speaker play audio according to the sound effect parameters shown in Figure 8A , which can achieve a sound field that is open and has a spatial sense of presence.

[0304] In some embodiments, in addition to the audio playing scene and the folding state, the electronic device 100 can also determine the sound effect parameters according to the horizontal and vertical screen state of the folding screen. For example, in the audio-video external playing scene shown in Figure 8A and the folding screen is in the unfolded state, if the folding screen is in the horizontal screen state, the electronic device 100 can play audio according to the sound effect parameters (such as parameters 11, parameters 12, and parameters 13) shown in Figure 8A . In this way, the user watches the video through the electronic device 100 in the horizontal screen state, and the top speaker and the bottom speaker can be equivalent to two sound boxes placed in front of the left and right of the user, which can achieve an open sound field effect on the left and right. ​

[0305] Figure 8B An audio playing method is shown.

[0306] S811, in the audio-video outdoor playing scene, the foldable screen is in the unfolded state.

[0307] S812, using the top speaker, the bottom speaker and the outer screen speaker to play the audio according to the sound effect parameter 5.

[0308] In some embodiments, in the audio-video outdoor playing scene, the audio to be played can be multi-channel audio. A channel can refer to an independent audio signal collected or played when sound is recorded or played in different spatial positions. Different channels can represent different sound sources. For example, multi-channel audio can include two-channel audio, 4.0 surround sound (including four channels), 5.1 surround sound (including six channels), and the like.

[0309] The electronic device 100 can match different sound sources to the top speaker, the bottom speaker and the outer screen speaker. Specifically, the electronic device 100 can perform channel separation on the audio to be played to obtain audio signals of different channels in the audio to be played. The electronic device 100 can assign the audio signals of different channels to the top speaker, the bottom speaker and the outer screen speaker. The top speaker, the bottom speaker and the outer screen speaker can play the audio signals of different channels. The embodiments of the present application do not limit the specific method of assigning different channels in the above multiple speakers.

[0310] The electronic device 100 can obtain the sound effect parameter of the audio to be played in the outdoor playing scene from the memory, for example, the sound effect parameter 5'. The sound effect parameter 5' can include loudness 5', EQ parameter 5'. In some embodiments, the sound effect parameter 5 can also include phase 5'.

[0311] During the process of playing the audio, the electronic device 100 can adjust the phase of the audio signal played by each speaker on the basis of the phase 5', so as to change the direction of the sound heard by the user. For example, the electronic device 100 can adjust the phase of the audio signal played by the top speaker to phase 5a, adjust the phase of the audio signal played by the outer screen speaker to phase 5b, and adjust the phase of the audio signal played by the bottom speaker to phase 5c. The embodiments of the present application do not limit the specific value of the phase of the audio signal played by each speaker in the electronic device 100. Among them, during the process of playing the audio, the phase of the audio signal played by each speaker in the electronic device 100 can be dynamically changed. In this way, the direction of the sound emitted by each sound object in the audio to be played can be adjusted in real time, and the spatial sense of presence of the user listening to the audio can be enhanced.

[0312] In the process of playing the audio, the electronic device 100 can also adjust the transfer function of the sound waves emitted by each speaker to the human ear. For example, the transfer function can be a head-related transfer function (HRTF). The HRTF can be used to describe how the human ear receives sound from a sound source point in space. Before the sound reaches the human ear, due to the different shapes and sizes of each person's head, pinna, and other structures that change the sound (for example, increase some frequencies, attenuate other frequencies), thus affecting the user's perception of the sound. Among them, changing the transfer function of the sound waves emitted by the speaker to the human ear can include changing the loudness and / or the EQ parameter. For example, the electronic device 100 can adjust the loudness of the audio signal played by the top speaker to loudness 5a, and adjust the EQ parameter to EQ parameter 5a. The electronic device 100 can adjust the loudness of the audio signal played by the outer screen speaker to loudness 5b, and adjust the EQ parameter to EQ parameter 5b. The electronic device 100 can adjust the loudness of the audio signal played by the bottom speaker to loudness 5c, and adjust the EQ parameter to EQ parameter 5c. The above loudness can be adjusted on the basis of loudness 5'. The above EQ parameter can be adjusted on the basis of EQ parameter 5'. The embodiments of the present application do not limit the specific values of the loudness and the EQ parameter of the audio signal played by each speaker.

[0313] That is, the above Figure 8A The parameter 11 can include loudness 5a, EQ parameter 5a, and phase 5a; the parameter 12 can include loudness 5b, EQ parameter 5b, and phase 5b; and the parameter 13 can include loudness 5c, EQ parameter 5c, and phase 5c. The sound effect parameter 5 can include the parameter 11, the parameter 12, and the parameter 13.

[0314] Based on the adjustment of one or more of the above phase, loudness, and EQ parameter, the electronic device 100 can simulate the sound of different positions through the top speaker, the outer screen speaker, and the bottom speaker, so that the user feels that the sound comes from the actual sound object in space when listening to the audio, thereby achieving a sound effect with spatial presence and an open sound field (which can be referred to as sound effect 1). The above method can allow the user to listen to the audio when the folding screen is in the unfolded state, especially in the scenario of watching a video, to feel an immersive experience. For example, the user hears the position of a sound object in the video that emits sound, which can be the same or similar to the position of the user in the video that sees the sound object. The above method can improve the listening experience of the user when the folding screen is in the unfolded state when playing an audio / video.

[0315] In some embodiments, the electronic device 100 can also detect the horizontal and vertical screen state of the folding screen. In the audio-video external playing scene, if the folding screen is in the unfolded state and in the horizontal screen state, the electronic device 100 can perform the above step S812. In the audio-video external playing scene, if the folding screen is in the unfolded state and in the vertical screen state, the electronic device 100 plays audio using the top speaker, the bottom speaker and the outer screen speaker according to the sound effect parameter 5'. Wherein, in the vertical screen state, the sound sources played by the top speaker, the bottom speaker and the outer screen speaker can be audio signals of different channels in the audio to be played. The embodiments of the present application do not limit the sound effect parameters of the audio played by the top speaker, the bottom speaker and the outer screen speaker in the above vertical screen state.

[0316] Figure 8C Another audio playing scene of external audio-video is shown.

[0317] As shown in Figure 8C , the folding screen is in the half-folded state, and the electronic device 100 is playing a video. The electronic device 100 can display a video playing interface 820. The electronic device 100 can play audio using the top speaker, the bottom speaker and the outer screen speaker. Wherein, the sound effect parameters when the top speaker, the bottom speaker and the outer screen speaker play audio can be different. For example, the top speaker can play audio according to parameter 21. The outer screen speaker can play audio according to parameter 22. The bottom speaker can play audio according to parameter 23. The above sound effect parameters will be introduced in detail in the subsequent embodiments, which will not be expanded here. Figure 8D

[0318] In some embodiments, in the audio-video external playing scene, the sound effect achieved by the electronic device 100 when playing audio in the half-folded state of the folding screen can be different from the sound effect achieved by the electronic device 100 when playing audio in the unfolded state of the folding screen. For example, the top speaker, the bottom speaker and the outer screen speaker play audio according to the sound effect parameters shown in Figure 8C , which can achieve the sound image centered and the vocal full sound effect.

[0319] Figure 8D An audio playing method provided by the present application is shown.

[0320] S821, in the audio-video external playing scene, the folding screen is in the half-folded state.

[0321] S822, play audio using the top speaker, the bottom speaker and the outer screen speaker according to the sound effect parameter 6.

[0322] ​In some embodiments, the electronic device 100 can match different sound sources to the top speaker, the bottom speaker, and the outer screen speaker. Specifically, the electronic device 100 can perform channel separation on the audio to be played to obtain audio signals of different channels in the audio to be played. The electronic device 100 can assign the audio signals of different channels to the top speaker, the bottom speaker, and the outer screen speaker. The top speaker, the bottom speaker, and the outer screen speaker can play the audio signals of different channels.

[0323] The electronic device 100 can obtain, from the memory, an audio effect parameter of the audio to be played in the outdoor playback scenario and when the folding screen is in the half-folded state, for example, the audio effect parameter 6'. The audio effect parameter 6' can be different from the audio effect parameter 5' in the step S812 shown in the foregoing embodiment. The audio effect parameter 5' can be an audio effect parameter of the audio to be played in the outdoor playback scenario and when the folding screen is unfolded. Alternatively, the audio effect parameter 6' and the audio effect parameter 5' can be the same. Figure 8B

[0324] The audio effect parameter 6' can include a loudness 6', an EQ parameter 6', and a phase 6'.

[0325] In the process of playing the audio, the electronic device 100 can adjust the phases of the audio signals played by the speakers based on the phase 6' to change the distance at which the user hears the sound. For example, the electronic device 100 can adjust the phase of the audio signal played by the top speaker to the phase 6a, adjust the phase of the audio signal played by the outer screen speaker to the phase 6b, and adjust the phase of the audio signal played by the bottom speaker to the phase 6c. The present embodiment does not limit the specific values of the phases of the audio signals played by the speakers in the electronic device 100. In the process of playing the audio, the phases of the audio signals played by the speakers in the electronic device 100 can be dynamically changed. In this way, the relative distance between each sound object in the audio to be played and the user can be adjusted in real time, and the sound image can be concentrated at the middle position of the electronic device 100.

[0326] The electronic device 100 can increase the weight of the sound waves emitted by the top speaker and the outer screen speaker, and decrease the weight of the sound waves emitted by the bottom speaker.

[0327] Specifically, the electronic device 100 can also increase the volume of the low-frequency band based on the EQ parameter 6' to obtain an EQ parameter 6a and an EQ parameter 6b. The electronic device 100 can decrease the volume of the low-frequency band based on the EQ parameter 6' to obtain an EQ parameter 6c. The top speaker can play the audio according to the EQ parameter 6a. The outer screen speaker can play the audio according to the EQ parameter 6b. The bottom speaker can play the audio according to the EQ parameter 6c. The above adjustment can achieve the audio effect of full-bodied vocals.

[0328] ​In some embodiments, the electronic device 100 can further adjust the loudness of the audio signals played by each speaker based on the loudness 6'. For example, the electronic device 100 can adjust the loudness of the audio signal played by the top speaker to loudness 6a, the loudness of the audio signal played by the external screen speaker to loudness 6b, and the loudness of the audio signal played by the bottom speaker to loudness 6c. Optionally, the loudness 6a and loudness 6b can be higher than loudness 6'. The loudness 6c can be lower than loudness 6'. The embodiments of this application do not limit the loudness of the audio signals played by each speaker.

[0329] In other words, the above Figure 8C Parameter 21 shown may include loudness 6a, EQ parameter 6a, and phase 6a; parameter 22 may include loudness 6b, EQ parameter 6b, and phase 6b; parameter 23 may include loudness 6c, EQ parameter 6c, and phase 6c. Sound effect parameter 6 may include parameters 21, 22, and 23.

[0330] Based on the aforementioned sound effect parameter 6, the electronic device 100 allows the user to identify that the location of the sound being heard is consistent with the location of the video screen, achieving a centered sound image and full vocals (which can be referred to as sound effect 2). The above method can improve the user's listening experience when the folded screen is in a semi-folded state.

[0331] Figure 8E This illustrates another audio playback scenario using external speaker audio / video.

[0332] like Figure 8E As shown, the foldable screen is in the closed state, and the electronic device 100 is playing music. The electronic device 100 can display a user interface 830. The user interface 830 may include one or more controls for user control of music playback. The electronic device 100 can play audio using a top speaker, a bottom speaker, and an external screen speaker. The sound effect parameters for the top speaker, bottom speaker, and external screen speaker when playing audio can be different. For example, the top speaker can play audio according to parameter 31. The external screen speaker can play audio according to parameter 32. The bottom speaker can play audio according to parameter 33. These sound effect parameters will be discussed later. Figure 8F The specific details of the embodiments are described in the examples, but will not be elaborated here.

[0333] In some embodiments, in audio / video external playback scenarios, the sound effect achieved by the electronic device 100 when playing audio with the folded screen in a closed state can be different from the sound effect achieved by the electronic device 100 when playing audio with the folded screen in both an unfolded and a semi-folded state. For example, the top speaker, bottom speaker, and external screen speaker described above are arranged according to... Figure 8E The sound effect parameters shown can achieve a loud external speaker volume and good low-frequency sound effect.

[0334] Figure 8F An audio playing method is shown.

[0335] S831, in the audio-video outdoor playing scene, the folding screen is in the closed state.

[0336] S832, using the top speaker, the bottom speaker and the outer screen speaker to play the audio according to the sound effect parameter 7.

[0337] In some embodiments, the electronic device 100 can match the same sound source for the top speaker, the bottom speaker and the outer screen speaker. Wherein, the electronic device 100 can send the audio to be played to the top speaker, the bottom speaker and the outer screen speaker. That is to say, in the audio-video outdoor playing scene and the folding screen is in the closed state, the audio played by the top speaker, the bottom speaker and the outer screen speaker can be the same.

[0338] The electronic device 100 can obtain the sound effect parameter of the audio to be played in the outdoor playing scene and the folding screen is in the closed state from the memory, for example, the sound effect parameter 7'. The sound effect parameter 7' can be different from the sound effect parameter 5' in the step S812 shown above. Or, the sound effect parameter 7' and the sound effect parameter 5' can also be the same. Figure 8B

[0339] The sound effect parameter 7' can include loudness 7', EQ parameter 7', phase 7'.

[0340] In some embodiments, the sound effect parameter 7 is the sound effect parameter 7'. That is to say, the parameters 31, the parameters 32 and the parameters 33 shown above can be the same, and all include the loudness 7', the EQ parameter 7' and the phase 7'. Figure 8E

[0341] It can be understood that in the closed state, the positions of the top speaker, the bottom speaker and the outer screen speaker are concentrated. The three speakers play the same audio signal according to the same audio parameter, which can realize in-phase superposition, and achieve the effect of low frequency enhancement and loudness improvement.

[0342] In some embodiments, the electronic device 100 can increase the volume of the low frequency band on the basis of the EQ parameter 7', to obtain the EQ parameter 7a, the EQ parameter 7b and the EQ parameter 7c. Wherein, the EQ parameter 7a, the EQ parameter 7b and the EQ parameter 7c can be the same or different. The top speaker can play the audio according to the EQ parameter 7a. The outer screen speaker can play the audio according to the EQ parameter 7b. The bottom speaker can play the audio according to the EQ parameter 7c. The above adjustment can enhance the volume of the low frequency band played by each speaker, and improve the sound effect of the low frequency band.

[0343] ​​Optionally, the electronic device 100 can increase the loudness of the audio signal played by each speaker on the basis of the loudness 7', to obtain the loudness 7a, the loudness 7b, and the loudness 7c. The top speaker can play the audio according to the loudness 7a. The outer screen speaker can play the audio according to the loudness 7b. The bottom wall speaker can play the audio according to the loudness 7c.

[0344] That is, the sound effect parameter 7 includes the parameter 31, the parameter 32, and the parameter 33. The parameter 31 can include the loudness 7a, the EQ parameter 7a, and the phase 7'. The parameter 32 can include the loudness 7b, the EQ parameter 7b, and the phase 7'. The parameter 33 can include the loudness 7c, the EQ parameter 7c, and the phase 7'.

[0345] The above embodiments can achieve low-frequency enhancement to a greater extent and improve the loudness of audio playback, so as to achieve a sound effect (which can be referred to as sound effect 3) of large external loudness and good low frequency. The above method can improve the listening experience of the user when the folding screen is in the closed state.

[0346] As can be seen from the above audio playback method in the audio-video external playback scenario, in different folding modes, the electronic device 100 can use different sound effect parameters to achieve corresponding sound effects (such as sound effect 1, sound effect 2, and sound effect 3). The above Figure 8B the sound effect parameter 5 shown in the above embodiment for achieving the sound effect 1, Figure 8D the sound effect parameter 6 shown in the above embodiment for achieving the sound effect 2, Figure 8F the sound effect parameter 7 shown in the above embodiment for achieving the sound effect 3 are only exemplary descriptions of the present application and should not be construed as limiting the present application.

[0347] In some embodiments, during the process of external audio-video playback, if the folding mode of the folding screen changes, the electronic device 100 can change the sound effect parameters of the audio played by the top speaker, the bottom speaker, and the outer screen speaker accordingly, to achieve the sound effect corresponding to the changed folding mode. For example, if the folding screen changes from the unfolded state to the half-folded state, the electronic device 100 can adjust the sound effect parameter from the sound effect parameter 5 to the sound effect parameter 6, so as to change the sound effect of the audio playback from the sound effect 1 to the sound effect 2. In this way, the user can adjust the folding mode according to personal needs when external audio-video is played, so as to experience the corresponding audio playback sound effect. This can improve the user's audio listening experience when using the folding screen.

[0348] In some embodiments, in the audio-video external playback scenario, the electronic device 100 can use one or two of the top speaker, the outer screen speaker, and the bottom speaker to play the audio. The present application does not limit the method for selecting the sound production device for playing the audio.

[0349] In the earphone playing scenario, the electronic device 100 may have a leakage problem when playing audio through the top speaker or the outer screen speaker at a small power. For example, in the handheld call scenario, a user holds the top speaker or the outer screen speaker close to the ear to answer the phone. The call audio played by the top speaker or the outer screen speaker may be heard by other people around the user. The above leakage problem may leak the user's privacy.

[0350] In some embodiments, in the earphone playing scenario, the electronic device 100 can play audio using the top speaker, the outer screen speaker, and the bottom wall speaker. The three speakers can play audio with opposite phases. In this way, the sound waves can be suppressed from spreading around by anti-phase cancellation, achieving the effect of reducing leakage.

[0351] Figure 9A An anti-leakage method is exemplarily shown.

[0352] S911, in the earphone playing scenario, the folding screen is in the unfolded state.

[0353] S912, playing audio using the top speaker, the outer screen speaker, and the bottom wall speaker, wherein the audio played by the outer screen speaker and the bottom wall speaker is opposite in phase to the audio played by the top speaker.

[0354] From the foregoing Figure 6A It can be known that, in the earphone playing scenario when the folding screen is in the unfolded state, the user is usually used to holding the top speaker close to the ear to listen to audio. Therefore, the electronic device 100 can take the top speaker as the main speaker and take the outer screen speaker and the bottom wall speaker as the auxiliary speakers. The main speaker can be equivalent to the earphone for the user to hold close to the ear to listen to audio. The auxiliary speakers can be used to reduce leakage.

[0355] Since the audio played by the outer screen speaker and the bottom wall speaker is opposite in phase to the audio played by the top speaker, the sound waves emitted by the outer screen speaker and the bottom wall speaker and the sound waves emitted by the top speaker will cancel each other out. The sound waves emitted by the top speaker, the bottom wall speaker, and the outer screen speaker will not be transmitted to a far place.

[0356] From the above method, it can be known that the electronic device 100 reduces leakage through the outer screen speaker and the bottom wall speaker when the folding screen is in the unfolded state. In this way, the user can hold the top speaker close to the ear to listen to audio without worrying that the audio listened to by himself will be heard by other people nearby.

[0357] In some embodiments, in the earphone playback scenario, if the folding screen is in the unfolded state, the electronic device 100 can take the outer screen loudspeaker or the bottom loudspeaker as the auxiliary loudspeaker. For example, the electronic device 100 can play audio using the top loudspeaker and the outer screen loudspeaker. The audio played by the top loudspeaker is opposite in phase to the audio played by the outer screen loudspeaker. The bottom loudspeaker can not need to play audio. Alternatively, the electronic device 100 can play audio using the top loudspeaker and the bottom loudspeaker. The audio played by the top loudspeaker is opposite in phase to the audio played by the bottom loudspeaker. The outer screen loudspeaker can not need to play audio.

[0358] Figure 9B Another method for preventing sound leakage is exemplarily shown.

[0359] S921, in the earphone playback scenario, the folding screen is in the closed state.

[0360] S922, audio is played using the top loudspeaker, the outer screen loudspeaker, and the bottom loudspeaker, wherein the audio played by the top loudspeaker and the bottom loudspeaker is opposite in phase to the audio played by the outer screen loudspeaker.

[0361] From the foregoing Figure 7A It can be known that, in the earphone playback scenario when the folding screen is in the closed state, the user is usually accustomed to placing the outer screen loudspeaker close to the ear to listen to audio. Therefore, the electronic device 100 can take the outer screen loudspeaker as the main loudspeaker, and take the top loudspeaker and the bottom loudspeaker as the auxiliary loudspeaker.

[0362] Since the audio played by the top loudspeaker and the bottom loudspeaker is opposite in phase to the audio played by the outer screen loudspeaker, the sound waves emitted by the top loudspeaker and the bottom loudspeaker and the sound waves emitted by the outer screen loudspeaker will cancel each other out. The sound waves emitted by the top loudspeaker, the bottom loudspeaker, and the outer screen loudspeaker will not propagate to a distance.

[0363] From the foregoing method, it can be known that the electronic device 100 reduces sound leakage through the top loudspeaker and the bottom loudspeaker when the folding screen is in the closed state. In this way, the user can place the outer screen loudspeaker close to the ear to listen to audio, and does not need to worry that the audio listened to by himself / herself will be heard by others nearby.

[0364] In some embodiments, in the earphone playback scenario, if the folding screen is in the closed state, the electronic device 100 can take the top loudspeaker or the bottom loudspeaker as the auxiliary loudspeaker. For example, the electronic device 100 can play audio using the top loudspeaker and the outer screen loudspeaker. The audio played by the top loudspeaker is opposite in phase to the audio played by the outer screen loudspeaker. The bottom loudspeaker can not need to play audio. Alternatively, the electronic device 100 can play audio using the outer screen loudspeaker and the bottom loudspeaker. The audio played by the outer screen loudspeaker is opposite in phase to the audio played by the bottom loudspeaker. The top loudspeaker can not need to play audio.

[0365] In some embodiments, in the earphone playback scenario, the electronic device 100 can adjust the sound effect parameters of the top speaker, the bottom speaker and the outer screen speaker to play audio, so as to achieve consistent effect of suppressing sound leakage in various directions of the sound field in which the electronic device 100 is located.

[0366] Figure 10 An exemplary diagram of the sound field in which the electronic device 100 is located is shown.

[0367] As shown in Figure 10 Region 1 can be a near-field region of the loudspeaker array composed of the top speaker, the outer screen speaker and the bottom speaker. The region outside region 1 can be a far-field region of the loudspeaker array composed of the top speaker, the outer screen speaker and the bottom speaker. Position L1 can be any one position point at a distance d1 from the electronic device 100. The above-mentioned distance d1 can be preset. The present application does not limit the value of the distance d1.

[0368] The electronic device 100 can adjust the volume of one or more frequency bands of the audio played by the top speaker, the outer screen speaker and the bottom speaker, so that the sound waves emitted by the top speaker, the outer screen speaker and the bottom speaker are completely cancelled or the residual sound wave energy is less than the energy threshold when propagating to any one position point (for example, position L1) at a distance d1 from the electronic device 100. In this way, in the earphone playback mode, the electronic device 100 plays audio according to the method shown in Figure 9A or Figure 9B When the user at a distance d1 and further from the electronic device 100 cannot hear the audio played by the top speaker, the outer screen speaker and the bottom speaker.

[0369] The present application does not limit the specific method of adjusting the volume of one or more frequency bands to achieve complete cancellation of sound waves emitted by the multiple speakers of the electronic device 100 at any position at a preset distance from the electronic device 100.

[0370] The above-mentioned embodiments can reduce sound leakage of the electronic device 100 in various directions, achieve better sound leakage prevention effect, and protect the privacy of the user when listening to audio in the earphone playback scenario.

[0371] The present application also provides a computer readable storage medium, which stores a computer program. When the computer program is executed by a processor, the steps in the above-mentioned various method embodiments can be implemented.

[0372] The present application also provides a computer program product, which includes a computer program. When the computer program runs on a processor, the steps in the above-mentioned various method embodiments can be implemented.
