[0011] Second aspect, an embodiment of the present application further provides an audio output method for an electronic device. The electronic device includes a flexible screen, a housing, a first speaker, and a second speaker. The flexible screen includes a first part, a second part, and an intermediate part. The first part and the second part are respectively rotatably connected to opposite sides of the intermediate part, so that the flexible screen presents a folded state or an unfolded state; the housing at least includes a first structure and a second structure that rotate relative to each other. The first structure carries the first part, and the second structure carries the second part; the first speaker is disposed on the first structure; the second speaker is disposed on the second structure; the method includes:

[0012] Obtain the state of the electronic device;

[0013] When the housing is in the folded state, the first speaker and the second speaker emit sounds of the same sound channel;

[0014] When the housing is in the unfolded state, the first speaker and the second speaker emit sounds of different sound channels.

[0015] In the embodiment of the present application, the first structure of the fuselage is provided with a first sound outlet hole for the first speaker to emit sound.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0028] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of the electronic device provided by the embodiment of the present application when in a folded state, Figure 2 is Figure 1 a schematic structural diagram of the electronic device shown when in an unfolded state, Figure 3 which is the first intermediate state diagram of the electronic device provided by the embodiment of the present application during the folding process. It can be understood that Figure 2The dashed lines therein only indicate the boundaries between the first part 21, the second part 22, and the middle part 23 of the flexible screen 20. An electronic device such as Figure 1 the electronic device 100 can be a computing device such as a laptop computer, a computer monitor including an embedded computer, a tablet computer, a cellular phone, a media player, or other handheld or portable electronic devices, a television, a computer display without an embedded computer, a gaming device, a navigation device, an embedded system (such as a system in which an electronic device with a display is installed in a kiosk or a vehicle), a device that implements the functions of two or more of these devices, or other electronic devices. In Figure 1 an exemplary configuration, the electronic device 100 is a portable device, such as a cellular phone, a media player, a tablet computer, or other portable computing devices. Other configurations can be used for the electronic device if needed. Figure 1 The examples are merely exemplary.

[0029] Among them, the electronic device 100 includes a housing 10, a flexible screen 20, a first speaker, and a second speaker. The flexible screen 20 includes a first part 21, a second part 22, and a middle part 23. The first part 21 and the second part 22 are respectively rotatably connected to opposite sides of the middle part 23 so that the flexible screen 20 can be in a folded state or an unfolded state.

[0030] The housing 10 at least includes a first structure 11 and a second structure 12 that rotate relative to each other. The first structure 11 carries the first part 21, and the second structure 12 carries the second part 22. It can be understood that the flexible screen 20 has a connection surface connected to the housing 10 and a display surface for displaying images. Specifically, the first part 21 has a first connection surface connected to the first structure 11, the second part 22 has a second connection surface connected to the second structure 12, and the first part 21, the second part 22, and the middle part 23 all have display surfaces. When the flexible screen 20 is in the folded state, the display surface of one of the first part 21, the second part 22, and the middle part 23 can display images. For example, the display surface of the first part 21 can display images. When the flexible screen 20 is in the unfolded state, the display surfaces of the first part 21, the second part 22, and the middle part 23 are coplanar and together form a display surface for displaying images.

[0031] It can also be understood that when the flexible screen 20 is in the folded state, correspondingly, the housing 10 is also in the folded state. When the flexible screen 20 is in the unfolded state, the housing 10 is also in the unfolded state. Among them, the folded state of the electronic device can be referred to Figure 1 which is the state finally formed when the first structure 11 and the second structure 12 move relative to each other in a direction close to each other. Among them, the unfolded state of the electronic device can be referred to Figure 2, that is, a state formed by relative movement of the first structure 11 and the second structure 12 in directions away from each other.

[0032] When the electronic device 100 is in the unfolded state, the first structure 11 and the second structure 12 are away from each other, and this state of the first structure 11 and the second structure 12 can be understood as being in the unfolded state. When the electronic device 100 is in the folded state, the first structure 11 and the second structure 12 are stacked together, and this state of the first structure 11 and the second structure 12 can be understood as being in the folded state.

[0033] The first speaker and the second speaker are components for outputting sound, wherein the first speaker is arranged on the first structure 11, and the first structure 11 is provided with a first sound outlet 111 for the first speaker to emit sound. The second speaker is arranged on the second structure 12, and the second structure 12 is provided with a second sound outlet 121 for the second speaker to emit sound. In this way, when the first speaker and the second speaker are working, sound can be emitted through the corresponding sound outlets.

[0034] Among them, the first sound outlet 111 and the second sound outlet 121 face the side where the display surface of the flexible screen 20 is located. When the flexible screen 20 is in the folded state and in the unfolded state, the first sound outlet 111 and the second sound outlet 121 are both located on the same side of the electronic device 100, and the first sound outlet 111 is staggered with the second structure 12, and the second sound outlet 121 is staggered with the first structure 11. In this way, when the user is using the electronic device 100, no matter whether the flexible screen 20 is in the folded state or in the unfolded state, the sound emitted by the first speaker and the second speaker can be emitted in the direction of the user's viewing, and because when the flexible screen 20 is in the folded state and in the unfolded state, the first sound outlet 111 is staggered with the second structure 12, and the second sound outlet 121 is staggered with the first structure 11, that is, the first sound outlet 111 will not be blocked by the second structure 12, and the second sound outlet 121 will not be blocked by the first structure 11, which effectively improves the sound effect and improves the user's experience.

[0035] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of this application are used to distinguish different objects, rather than to describe a specific order, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] To more clearly illustrate the specific structure of the electronic device 100, the following will specifically describe the relevant components of the electronic device 100 in conjunction with the accompanying drawings.

[0037] Please refer to Figure 4 and in conjunction with Figures 1 to 3 , Figure 4 which is a schematic structural diagram of the housing of the electronic device provided in the embodiment of the present application. The first structure 11 may include a first end portion 112 and a first bearing portion 113. The first end portion 112 is connected to one end of the first bearing portion 113. The first portion 21 is carried on the first bearing portion 113, and along the display surface direction of the flexible screen 20, the first end portion 112 and the first portion 21 are arranged side by side. The first sound outlet hole 111 is provided in the first end portion 112. In this way, when the first portion 21 is carried on the first structure 11, the first portion 21 does not block the first sound outlet hole 111, nor is it necessary to provide an avoidance hole position on the first portion 21 to avoid the first sound outlet hole 111.

[0038] It can be understood that the second structure 12 may include a second end portion 122 and a second bearing portion 123. The second end portion 122 is connected to one end of the second bearing portion 123. The second portion 22 is carried on the second bearing portion 123, and along the display surface direction of the flexible screen 20, the second end portion 122 and the second portion 22 are arranged side by side. The second sound outlet hole 121 is provided in the second end portion 122. In this way, when the second portion 22 is carried on the second structure 12, the second portion 22 does not block the second sound outlet hole 121, nor is it necessary to provide an avoidance hole position on the second portion 22 to avoid the second sound outlet hole 121.

[0039] Taking the example that the electronic device 100 is in a cuboid shape in the folded state, please refer to Figure 1 , when the electronic device 100 is in the folded state, the width direction is the first direction (or the X direction), the length direction is the second direction (or the Y direction), and the X direction and the Y direction are parallel to the display surface. Among them, the first end portion 112 and the first portion 21 are arranged side by side in the Y direction, the second end portion 122 and the second portion 22 are arranged side by side in the Y direction, and the first end portion 112 and the second end portion 122 are located on the same side of the flexible screen 20 in the Y direction.

[0040] In order to make the first sound outlet hole 111 and the second sound outlet hole 121 be located on the same side of the electronic device 100 when the flexible screen 20 is in the folded state and in the unfolded state, in some embodiments, please refer to Figure 5 , Figure 5This is the second intermediate state diagram of the electronic device provided by the embodiments of the present application during the folding process. The first part 21 of the flexible screen 20 can rotate relative to the middle part 23 and is stacked on one side of the middle part 23 away from the display surface of the middle part 23. The second part 22 of the flexible screen 20 can rotate relative to the middle part 23 and is stacked on one side of the middle part 23 away from the display surface of the middle part 23. In this way, when the flexible screen 20 is in a folded state, the first sound outlet 111 and the second sound outlet 121 are located on the same side of the electronic device 100, that is, the first sound outlet 111 and the second sound outlet 121 are located on the side of the middle part 23 away from the display surface of the middle part 23.

[0041] It can be understood that when the flexible screen 20 of this structure is in a folded state, the display surfaces of the first part 21, the second part 22, and the middle part 23 are all exposed. At this time, there is no need to add an extra outer screen (or a secondary screen) for the user to use when the electronic device 100 is in a folded state.

[0042] After research by the inventor, it is found that when the flexible screen 20 is in a folded state and the display surfaces of the first part 21, the second part 22, and the middle part 23 are all exposed, the risk of the electronic device 100 being broken is increased.

[0043] Based on this, please refer to Figures 1 to 3 , in some embodiments, when the flexible screen 20 is in a folded state, the middle part 23 is stacked on one side of the first structure 11 away from the first part 21, and the second part 22 and the second structure 12 are stacked on one side of the middle part 23 away from the first part 21. In this way, when the flexible screen 20 is in a folded state, the second part 22 and the middle part 23 of the flexible screen 20 are folded between the first structure 11 and the second structure 12 of the housing 10 and are protected. The display surface of the first part 21 can still be displayed to the outside for the user to operate and view. And, the first sound outlet 111 and the second sound outlet 121 are located on the side where the display surface of the first part 21 is located. In this way, when the user is watching the picture displayed on the display surface of the first part 21, the sound can be emitted from the side where the display surface is located and in the direction of the user's viewing, and the sound effect heard by the user is better.

[0044] It can be understood that when the flexible screen 20 is in an unfolded state, the first part 21, the middle part 23, and the second part 22 are coplanar.

[0045] Among them, in order to prevent the overall thickness of the electronic device 100 from being too thick when the flexible screen 20 is in a folded state, a first avoidance space 114 may be provided on the side of the first structure 11 away from the first portion 21. When the flexible screen 20 is in a folded state, the second portion 22, the middle portion 23, and the second structure 12 are received in the first avoidance space 114, and the second structure 12 is flush with the surface of the first structure 11 away from the first portion 21. In this way, the overall thickness of the electronic device 100 can be approximately equal to the thickness of the first structure 11, rather than the sum of the thickness of the first structure 11, the thickness of the middle portion 23, and the thickness of the second structure 12, greatly reducing the overall thickness of the electronic device 100.

[0046] Exemplarily, the area of the first portion 21 of the flexible screen 20 may be approximately half of the total area of the flexible screen 20 when it is unfolded. The areas of the second portion 22 and the middle portion 23 may be approximately equal, and the areas of the second portion 22 and the middle portion 23 are each approximately equal to half of the area of the first portion 21. In this way, when the flexible screen 20 is in a folded state, the middle portion 23 is stacked on a part of the first structure 11, and the unstacked part of the first structure 11 can then provide an installation space for installing other components, improving the utilization rate of the first structure 11.

[0047] As Figure 1 and Figure 2 As shown, when the flexible screen 20 is in an unfolded state, a second avoidance space 117 is provided on the side of the first end 112 facing the second end 122. When the flexible screen 20 is in a folded state, the second end 122 is located in the second avoidance space 117. In this way, when the flexible screen 20 is in a folded state, the second end 122 will not be blocked by the first end 112, so as to prevent the second sound outlet hole 121 from being blocked by the first end 112.

[0048] Among them, as Figure 3 shown, the first end 112 may include a first surface 1121, a second surface 1122, and a third surface 1123. The first surface 1121 is on the same side as the display surface of the flexible screen 20, the third surface 1123 faces away from the display surface of the flexible screen 20, the second surface 1122 is connected between the first surface 1121 and the third surface 1123, and the second surface 1122 is away from the flexible screen 20. The second end 122 may include a first surface 1221, a second surface 1222, and a third surface 1223. The first surface 1221 is on the same side as the display surface of the flexible screen 20, the third surface 1223 faces away from the display surface of the flexible screen 20, the second surface 1222 is connected between the first surface 1221 and the third surface 1223, and the second surface 1222 is away from the flexible screen 20.

[0049] When the flexible screen 20 is in a folded state, the first surface 1121 is flush with the first surface 1221, and / or the second surface 1122 is flush with the second surface 1222, and / or the third surface 1123 is flush with the third surface 1223. With such a setting, the overall structure of the electronic device 100 is more compact and aesthetically pleasing after folding.

[0050] Among them, when the flexible screen 20 is in a folded state, in order to further make the overall structure of the electronic device 100 more compact, the electronic device 100 can be set such that when the flexible screen 20 is in a folded state, the first end 112 abuts against the second end 122.

[0051] Of course, in some embodiments, when the flexible screen 20 is in a folded state, there may also be a gap between the first end 112 and the second end 122.

[0052] When the flexible screen 20 is in a folded state, the first end 112 and the second end 122 are adjacently arranged, and the value range of the minimum edge distance between the first sound outlet hole 111 corresponding to the first speaker and the second sound outlet hole 121 corresponding to the second speaker is between 1 millimeter and 2 millimeters. The adjacent arrangement of the first sound outlet hole 111 and the second sound outlet hole 121 can make the played sound similar to stereo, and the sound effect is better.

[0053] When the flexible screen 20 is in an unfolded state, the first part 21, the middle part 23, and the second part 22 are coplanar. The first part 21 is carried by the first structure 11, and the second part 22 is carried by the second structure 12. In order to make the structure of the flexible screen 20 more stable when it is in an unfolded state. In some embodiments, the housing 10 may further include a third structure 13. The first structure 11 and the second structure 12 are respectively rotatably connected to opposite sides of the third structure 13, and the third structure 13 carries the middle part 23. Thus, when the flexible screen 20 is in an unfolded state, under the load of the first structure 11, the second structure 12, and the third structure 13, the structure of the flexible screen 20 after unfolding can be more stable.

[0054] Among them, the first structure 11 and the second structure 12 can be respectively rotatably connected to opposite sides of the third structure 13 through hinges.

[0055] In some embodiments, please refer to Figure 1 and Figure 2, the electronic device 100 may further include a third speaker and a fourth speaker. The first structure 11 may further include a third end portion 115. The third end portion 115 is connected to one end of the first bearing portion 113 away from the first end portion 112. And along the display surface direction of the flexible screen 20, the third end portion 115 and the first portion 21 are arranged side by side, and the third end portion 115 and the first end portion 112 are located on opposite sides of the first portion 21. The third speaker is disposed on the third end portion 115. The third end portion 115 is provided with a third sound outlet hole 116 for the third speaker to emit sound. The third sound outlet hole 116 faces the side where the display surface of the flexible screen 20 is located. In this way, when the first portion 21 is carried by the first structure 11, the first portion 21 does not block the third sound outlet hole 116, nor is it necessary to provide an avoidance hole position on the first portion 21 to avoid the third sound outlet hole 116.

[0056] The second structure 12 may further include a fourth end portion 125. The fourth end portion 125 is connected to one end of the second bearing portion 123 away from the second end portion 122. And along the display surface direction of the flexible screen 20, the fourth end portion 125 and the second portion 22 are arranged side by side, and the fourth end portion 125 and the second end portion 122 are located on opposite sides of the second portion 22. The fourth speaker is disposed on the fourth end portion 125. The fourth end portion 125 is provided with a fourth sound outlet hole 126 for the fourth speaker to emit sound. The fourth sound outlet hole 126 faces the side where the display surface of the flexible screen 20 is located. In this way, when the second portion 22 is carried by the second structure 12, the second portion 22 does not block the fourth sound outlet hole 126, nor is it necessary to provide an avoidance hole position on the second portion 22 to avoid the fourth sound outlet hole 126.

[0057] When the flexible screen 20 is in the unfolded state, a third avoidance space 118 is provided on the side of the third end portion 115 facing the fourth end portion 125. When the flexible screen 20 is in the folded state, the fourth end portion 125 is located in the third avoidance space 118. In this way, when the flexible screen 20 is in the folded state, the fourth end portion 125 is not blocked by the third end portion 115, so as to prevent the fourth sound outlet hole 126 from being blocked by the third end portion 115.

[0058] Wherein, the third end portion 115 may include a fourth surface, a fifth surface and a sixth surface. The fourth surface is on the same side as the display surface of the flexible screen 20, the sixth surface faces away from the display surface of the flexible screen 20, the fifth surface is connected between the fourth surface and the sixth surface, and the fifth surface is away from the flexible screen 20. The fourth end portion 125 may include a fourth surface, a fifth surface and a sixth surface. The fourth surface is on the same side as the display surface of the flexible screen 20, the sixth surface faces away from the display surface of the flexible screen 20, the fifth surface is connected between the fourth surface and the sixth surface, and the fifth surface is away from the flexible screen 20.

[0059] When the flexible screen 20 is in a folded state, the fourth surface is flush with the fourth face, and / or the fifth surface is flush with the fifth face, and / or the sixth surface is flush with the sixth face. Such an arrangement makes the overall structure of the electronic device 100 more compact and aesthetically pleasing after folding.

[0060] Among them, when the flexible screen 20 is in a folded state, in order to further make the overall structure of the electronic device 100 more compact, the electronic device 100 can be arranged such that when the flexible screen 20 is in a folded state, the third end portion 115 abuts against the fourth end portion 125.

[0061] Of course, in some embodiments, when the flexible screen 20 is in a folded state, there may also be a gap between the third end portion 115 and the fourth end portion 125.

[0062] It can be understood that when the flexible screen 20 is in a folded state, the third end portion 115 and the fourth end portion 125 are adjacently arranged, and the minimum edge distance between the third sound outlet hole 116 corresponding to the third speaker and the fourth sound outlet hole 126 corresponding to the fourth speaker can be in the range of 1 millimeter to 2 millimeters. The adjacent arrangement of the third sound outlet hole 116 and the fourth sound outlet hole 126 can make the played sound similar to stereo, and the sound effect is better.

[0063] It can also be understood that the first speaker, the second speaker, the third speaker, and the fourth speaker can be used as speakers for external sound or as receivers (or say earpieces), and the present application does not limit this here.

[0064] In some embodiments, the electronic device 100 may further include a gravity sensor and a control chip. The gravity sensor and the control chip can be disposed in the housing 10. The control chip is connected to the first speaker, the second speaker, the third speaker, and the fourth speaker. The gravity sensor is configured to obtain the direction signal of the housing 10 and feedback it to the control chip, and the control chip is configured to control the working states of the first speaker, the second speaker, the third speaker, and the fourth speaker according to the direction signal of the housing 10. For example, the control chip can control the first speaker, the second speaker, the third speaker, and the fourth speaker to switch channels according to the direction signal of the housing 10, or the control chip can control the first speaker, the second speaker, the third speaker, and the fourth speaker to be turned on or off according to the direction signal of the housing 10.

[0065] Exemplarily, the control chip can control the first speaker, the second speaker, the third speaker, and the fourth speaker to switch channels according to the direction signal of the housing 10. Please refer to Figure 2, when the flexible screen 20 is in the unfolded state, the first speaker, the second speaker, the third speaker, and the fourth speaker are far from each other and are generally located at the four corners of the electronic device 100. For example, the first speaker is generally located at the upper left corner, the second speaker is generally located at the upper right corner, the third speaker is generally located at the lower left corner, and the fourth speaker is generally located at the lower right corner. It can be understood that Figure 2 the positions of the first sound outlet 111, the second sound outlet 121, the third sound outlet 116, and the fourth sound outlet 126 in Figure 2 can generally represent the positions of the first speaker, the second speaker, the third speaker, and the fourth speaker. Among them, the first speaker can play the sound of the first channel, the second speaker can play the sound of the second channel, the third speaker can play the sound of the third channel, and the fourth speaker can play the sound of the fourth channel, so as to achieve the effect of panoramic surround sound. When the electronic device 100 rotates 180 degrees, as Figure 6 shown Figure 6 is Figure 2 the schematic structural diagram of the electronic device shown in Figure 6 after being flipped 180 degrees. At this time, the physical positions of the speakers have changed. The first speaker is generally located at the lower right corner, the second speaker is generally located at the lower left corner, the third speaker is generally located at the upper right corner, and the fourth speaker is generally located at the upper left corner. At this time, the gravity sensor can sense that the direction of the housing 10 has changed. In order to adapt to the picture displayed on the flexible screen 20, it is still necessary to play the sound of the first channel at the upper left corner of the electronic device 100, play the sound of the second channel at the upper right corner of the electronic device 100, play the third channel at the lower left corner of the electronic device 100, and play the fourth channel at the lower right corner of the electronic device 100. Therefore, the control chip can control the first speaker, the second speaker, the third speaker, and the fourth speaker to switch channels according to the direction change signal of the housing 10. Specifically, the fourth speaker located at the upper left corner at this time can be switched to the first channel, the third speaker located at the upper right corner at this time can be switched to the second channel, the second speaker located at the lower left corner at this time can be switched to the third channel, and the first speaker located at the lower right corner at this time can be switched to the fourth channel. In this way, the sound output position heard by the user will not change with the rotation of the housing 10, so as to ensure that the sound of each channel can be output from the speaker in a specific direction.

[0066] It can be understood that the electronic device 100 may further include a first battery, a second battery, a first circuit board, and a second circuit board. The first circuit board is electrically connected to the second circuit board. The first battery and the first circuit board may be disposed in the first structure 11, and the first battery is electrically connected to the first circuit board. The second battery and the second circuit board are disposed in the second structure 12, and the second battery is electrically connected to the second circuit board. Among them, the control chip may be integrated on the first circuit board or the second circuit board.

[0067] On the other hand, an embodiment of the present application further provides an audio output method for an electronic device 100. Herein, the electronic device 100 may be the above-mentioned electronic device 100. When the electronic device 100 includes a first speaker and a second speaker, please refer to Figure 7 , Figure 7 which is the first flowchart of the audio output method provided by the embodiment of the present application. The audio output method includes:

[0068] 101: Obtain the state of the electronic device 100. For example, obtain the folded state or unfolded state of the electronic device 100.

[0069] 102: When the housing 10 is in the folded state, the first speaker and the second speaker emit sounds of the same channel. In this way, the played sound can be made to resemble stereo sound, and the sound effect is better.

[0070] 103: When the housing 10 is in the unfolded state, the first speaker and the second speaker emit sounds of different channels. In this way, the played sound can be made to resemble surround sound.

[0071] When the electronic device 100 includes a first speaker, a second speaker, a third speaker, and a fourth speaker, please refer to Figure 8 and Figure 9 , Figure 8 which is the second flowchart of the audio output method provided by the embodiment of the present application, Figure 9 and Figure 9 which is the third flowchart of the audio output method provided by the embodiment of the present application. The audio output method includes:

[0072] 104: Obtain the state of the electronic device 100.

[0073] 105: When the housing 10 is in the folded state, the first speaker and the second speaker emit sounds of the same channel, and the third speaker and the fourth speaker emit sounds of another channel. In this way, the played sound can be made to resemble stereo sound, and the sound effect is better than that of a dual-speaker system.

[0074] 106: When the housing 10 is in the unfolded state, the first speaker, the second speaker, the third speaker, and the fourth speaker each emit sounds of different channels. For example, the first speaker can play the sound of the first channel, the second speaker can play the sound of the second channel, the third speaker can play the sound of the third channel, and the fourth speaker can play the sound of the fourth channel, thereby achieving the effect of panoramic surround sound.

[0075] Among them, step 106 can be replaced with step 107. Specifically, step 107 can be: when the casing 10 is in the unfolded state, the first speaker and the third speaker emit sounds of the same sound channel, and the second speaker and the fourth speaker emit sounds of another sound channel. In this way, a panoramic surround sound effect can also be achieved.
