[0035] It should be noted that Figure 1 In the figure, the first body 10 and the second body 13 are folded relative to each other for illustration.

[0036] In the embodiment of the present application, the electronic device may be a foldable screen electronic device, wherein the first body 10 and the second body 13 of the electronic device may be rotatably connected via a connector (e.g., a hinge in the following embodiment).

[0037] Optionally, in an embodiment of the present application, the above-mentioned first body 10 may include a first frame, a printed circuit board (PCB), a speaker unit 12, a battery, a first battery cover and a first screen portion, wherein the first frame, the first battery cover and the first screen portion together form an inner cavity of the first body 10, and the PCB, the speaker unit 12 and the battery are all arranged in the inner cavity of the first body 10; the above-mentioned second body 13 may include a second frame, a second battery cover and a second screen portion, wherein the second frame, the second battery cover and the second screen portion together form the inner cavity of the second body 13.

The first sealing member 14 may be disposed outside the inner cavity of the second body 13 and / or outside the inner cavity of the first body 10 .

[0039] It should be noted that in order to more clearly illustrate the structure of the electronic device, Figure 2 FIG1 shows an exploded schematic diagram of an electronic device provided in an embodiment of the present application. Taking the first sealing member 14 as an example, the first sealing member 14 is arranged outside the inner cavity of the second body 13. Figure 2 As shown, the first body 10 includes a first frame 101, a PCB 102, a speaker unit 12, a battery 103, a first battery cover 104 and a first screen portion 105, wherein the first frame 101, the first battery cover 104 and the first screen portion 105 together form an inner cavity of the first body 10, and the PCB 102, the speaker unit 12 and the battery 103 are all arranged in the inner cavity of the first body 10; the second body 13 includes a second frame 131, a second battery cover 132 and a second screen portion 133, wherein the second frame 131, the second battery cover 132 and the second screen portion 133 together form the inner cavity of the second body 13, and the first sealing member 14 is arranged outside the inner cavity of the second body 13.

[0040] Optionally, in the embodiment of the present application, the PCB, the battery, and the first battery cover in the inner cavity of the first body 10 can be enclosed to form a first rear cavity 11 .

[0041] Optionally, in the embodiment of the present application, the first rear cavity 11 may be connected to the speaker unit 12 through a first cavity channel. The first cavity channel may be enclosed by the first battery cover and the PCB.

[0042] It should be noted that, in order to more clearly illustrate the first cavity channel, Figure 3 Shown Figure 1 The enlarged schematic diagram of A shown in FIG. Figure 3 As shown, the first battery cover 104 and the PCB 102 together form a first cavity channel 106 , and the first rear cavity 11 can be connected to the speaker unit 12 through the first cavity channel 106 .

[0043] It can be understood that the first rear cavity 11 can be regarded as the rear cavity of the speaker unit 12.

[0044] Optionally, in the embodiment of the present application, a first opening communicating with the first rear cavity 11 is provided at a position of the first body 10 close to the connecting member (such as a hinge in the following embodiment).

[0045] Further optionally, in the embodiment of the present application, a first opening is provided on the first surface of the first body 10 close to the connector. The first surface of the first body 10 may be the surface where the first screen portion 105 is provided.

[0046] In the embodiment of the present application, the first sealing member 14 is used to seal the space between the first body 10 and the second body 13 when the first body 10 and the second body 13 are folded relative to each other.

[0047] Optionally, in the embodiment of the present application, the first sealing component 14 may specifically be a sealing cushion.

[0048] Optionally, in the embodiment of the present application, the first sealing member 14 may be any one of the following: annular, rectangular, oblong, irregular shape, etc.

[0049] Optionally, in an embodiment of the present application, when a first seal 14 is provided on the second body 13, the first seal 14 can be provided on any surface of the second body 13; when a first seal 14 is provided on the first body 10, the first seal 14 can be provided on any surface of the first body 10.

[0050] Further optionally, in the embodiment of the present application, the first sealing member 14 can be provided on the second frame 131 of any surface of the second body 13; the first sealing member 14 can be provided on the first frame 101 of any surface of the first body 10.

[0051] For example, in combination Figure 2 The first sealing member 14 can be arranged on the second frame 131 on the top surface of the second body 13 (ie, the top surface shown in the figure).

[0052] The following description will be made by taking the second body 13 provided with the first sealing member 14 as an example.

[0053] In one example, a first sealing member 14 is provided at an edge of the second surface of the second body 13. When the first body 10 and the second body 13 are folded relative to each other, the second surface of the second body 13 is close to the first body 10.

[0054] It can be understood that the second side of the second body 13 is: a side of the second body 13 where the second screen portion 133 is provided.

[0055] Optionally, in the embodiment of the present application, on the second frame 131 on the second surface of the second body 13 .

[0056] As can be seen, since the first sealing member can be disposed at the edge of the second surface of the second body, the volume of the second rear cavity enclosed by the first body, the second body and the first sealing member can be increased.

[0057] In the embodiment of the present application, when the first body 10 and the second body 13 are folded relative to each other, the first body 10, the second body 13 and the first sealing member 14 together form a second rear cavity 15, and the first rear cavity 11 is connected to the second rear cavity 15 through the first opening.

[0058] Optionally, in the embodiment of the present application, the first screen portion 105 , the second screen portion 133 and the first sealing member 14 may be combined to form a second rear cavity 15 .

[0059] It should be noted that, in order to more clearly illustrate the second rear cavity 15, Figure 4 Shown Figure 1 The enlarged schematic diagram of B is shown in FIG. Figure 4 As shown, the first screen portion 105 , the second screen portion 133 and the first seal 14 together enclose a second rear cavity 15 .

[0060] In one example, the first rear cavity 11 may be directly connected to the second rear cavity 15 through the first opening and the first screen portion 105 (and / or the second screen portion 133 ).

[0061] It can be understood that when the first body 10 and the second body 13 are folded relative to each other, the first screen portion 105 and the second screen portion 133 are in a relaxed state. At this time, there is a first gap between the first screen portion 105 and the first frame 101, and there is a second gap between the second screen portion 133 and the second frame 131. Therefore, the first rear cavity 11 can be directly connected to the second rear cavity 15 through the first opening and the first gap (and / or the second gap); when the first body 10 and the second body 13 are unfolded relative to each other, the first screen portion 105 and the second screen portion 133 are in a taut state. At this time, the first screen portion 105 and the first frame 101 are in contact with each other, and the second screen portion 133 and the second frame 131 are in contact with each other to seal the first rear cavity 11.

[0062] In another example, the first rear cavity 11 may be in communication with the second rear cavity 15 through the first opening, other structures (eg, the movable structure in the following embodiments), and the first screen portion 105 (and / or the second screen portion 133 ).

[0063] In this example, the electronic device further includes a movable structure, which is disposed at the first opening and is movable relative to the first body 10 .

[0064] Optionally, in the embodiment of the present application, the movable structure is disposed in a target area of the first surface of the first body 10. The target area is an area within a preset range of the first opening.

[0065] Optionally, in one possible implementation, a sensor of the electronic device can detect the folding state between the first body 10 and the second body 13, and send a signal to the electronic device based on the detected folding state (e.g., relative folding or relative unfolding), so that the electronic device can control the relative movement of the movable structure and the first body 10 based on the signal. The sensor can include at least one of the following: a button sensor, a capacitive sensor, a Hall sensor, etc.

[0066] Optionally, in another possible implementation, the movable structure may be connected to a connecting member (such as a hinge in the following embodiment) and moved relative to the first body 10 by being driven by the connecting member.

[0067] In the embodiment of the present application, when the first body 10 and the second body 13 are folded relative to each other, the movable end of the movable structure is away from the first opening, so that the first rear cavity 11 is connected to the second rear cavity 15 through the first opening.

[0068] It can be understood that when the first rear cavity 11 is connected to the second rear cavity 15 through the first opening, the first rear cavity 11 and the second rear cavity 15 can be regarded as the rear cavities of the speaker unit 12.

[0069] For example, Figure 5 FIG. 1 shows a frequency response curve of playing an audio file when the first rear cavity 11 and the second rear cavity 15 are connected. Figure 5 As shown, when the first rear cavity 11 is connected to the second rear cavity 15 , due to the increase in the volume of the rear cavity of the speaker unit 12 , the low-frequency performance of the electronic device when playing audio files through the speaker unit 12 is significantly improved.

[0070] Optionally, in one possible implementation, the sensor of the electronic device can send a signal to the electronic device based on the acquired folding state (i.e., relative folding), so that the electronic device can control the moving end of the moving structure to move in one direction according to the signal, so that the moving end of the moving structure can move away from the first opening.

[0071] Optionally, in another possible implementation, during the relative folding of the first body 10 and the second body 13 , the connecting member may drive the movable end of the movable structure to move in one direction, so that the movable end of the movable structure may move away from the first opening.

[0072] It can be seen that when the first body and the second body are relatively folded, the moving end of the movable structure can be away from the first opening, so that the first rear cavity is connected to the second rear cavity through the first opening, thereby increasing the volume of the rear cavity of the speaker unit.

[0073] In the embodiment of the present application, during the relative expansion of the first body 10 and the second body 13 , the moving end of the movable structure blocks the first opening.

[0074] It can be understood that when the moving end of the moving structure blocks the first opening, the first rear cavity 11 can be regarded as the rear cavity of the speaker unit 12.

[0075] Optionally, in an embodiment of the present application, the moving end of the moving structure may be in contact with the first opening to cover the first opening.

[0076] Optionally, in one possible implementation, the sensor of the electronic device can send another signal to the electronic device based on the acquired folding state (i.e., relative unfolding), so that the electronic device can control the moving end of the moving structure to move in another direction according to the other signal, so that the moving end of the moving structure can block the first opening.

[0077] Optionally, in another possible implementation, during the relative expansion of the first body 10 and the second body 13 , the connecting member may drive the movable end of the movable structure to move in another direction, so that the movable end of the movable structure may cover the first opening.

[0078] In the embodiment of the present application, during the relative expansion of the first body 10 and the second body 13, the first body 10, the second body 13 and the first sealing member 14 cannot be combined to form the second rear cavity 15. Therefore, the moving end of the movable structure can block the first opening to prevent other substances (such as water, dust, etc.) from entering the first rear cavity 11.

[0079] It can be seen that, since the movable end of the movable structure can cover the first opening to seal the first rear cavity during the relative expansion of the first body and the second body, the waterproof and dustproof capabilities of the electronic device can be improved.

[0080] Of course, in order to further improve the waterproof and dustproof capabilities of the electronic device, other sealing members may be provided between the movable structure and the first opening, which will be described below with examples.

[0081] Optionally, in an embodiment of the present application, the electronic device further includes: a second sealing member, which is arranged between the moving structure and the first opening.

[0082] Further optionally, in an embodiment of the present application, a second sealing member may be provided at the first opening.

[0083] Further optionally, in the embodiment of the present application, the second sealing member may specifically be: sealing foam.

[0084] As can be seen, since a second sealing member can be provided between the movable structure and the first opening to seal the first rear cavity during the relative expansion of the first body and the second body, the waterproof and dustproof capabilities of the electronic device can be improved.

[0085] The electronic device provided in the embodiment of the present application includes a first body provided with a first rear cavity (the first rear cavity is connected to the speaker unit of the electronic device), a second body and a first sealing member provided on the first body (and / or the second body), the second body is rotatably connected to the first body, so that when the first body and the second body are folded relative to each other, the first body, the second body and the first sealing member can be combined to form a second rear cavity, and the first rear cavity can be connected to the second rear cavity through the first opening of the first rear cavity. Since when the first body and the second body are folded relative to each other, the first body, the second body and the first sealing member can be combined to form a second rear cavity, and the second rear cavity can be connected to the rear cavity of the speaker unit (i.e., the first rear cavity), that is, the first rear cavity and the second rear cavity can be regarded as the rear cavity of the speaker unit, therefore, the volume of the rear cavity of the speaker unit can be increased, so that the effect of the electronic device in playing audio files through the speaker unit can be improved.

[0086] It can be understood that in the embodiment of the present application, there is no need to change the structure of the electronic device. Instead, a first seal is provided to increase the volume of the rear cavity of the speaker unit when the first body and the second body are relatively folded. Therefore, the effect of the electronic device in playing audio files through the speaker unit can be improved without increasing costs.

[0087] The following will illustrate the mobile structure with different examples.

[0088] Optionally, in the embodiment of the present application, Figure 6 As shown, the moving structure includes: a driving member 17 , which is disposed at the first opening 16 ; and a moving member 18 , which is connected to the driving member 17 .

[0089] Further optionally, in the embodiment of the present application, combined with Figure 6 A second sealing member 181 is further provided between the moving member 18 and the first opening 16 .

[0090] Further optionally, in the embodiment of the present application, the driving member 17 may be any one of the following: an electric member, a movable member, etc. The electric member may be any one of the following: an electric telescopic rod, a motor, etc.; the movable member may be any one of the following: a rotating rod, a push rod, etc.

[0091] In the embodiment of the present application, the above-mentioned moving member 18 can be regarded as the moving end of the moving structure.

[0092] Further optionally, in the embodiment of the present application, the moving member 18 may specifically be a moving block.

[0093] Further optionally, in the embodiment of the present application, the end of the moving member 18 away from the driving member 17 may be an inclined surface or a flat surface.

[0094] In the embodiment of the present application, when the first body 10 and the second body 13 are folded relative to each other, the driving member 17 drives the moving member 18 to move along the first direction, so that the moving member 18 is away from the first opening 16 .

[0095] Further optionally, in the embodiment of the present application, the first direction may specifically be: a direction away from the connecting member (such as the hinge in the following embodiment).

[0096] In the embodiment of the present application, when the first body 10 and the second body 13 are relatively unfolded, the driving member 17 drives the moving member 18 to move along the second direction so that the moving member 18 covers the first opening 16 ; the first direction and the second direction are different.

[0097] Further optionally, in the embodiment of the present application, the second direction may specifically be a direction toward the connecting member. It is understood that the first direction may be opposite to the second direction.

[0098] It can be seen that since the driving member can be used to drive the movable member to move in different directions to control whether the movable member blocks the first opening, and then it can be quickly controlled whether the first rear cavity is connected to the second rear cavity, the effect of the electronic device playing audio files through the speaker unit can be quickly improved.

[0099] Example 1:

[0100] In this example, the driving component is an electric component as an example for explanation.

[0101] Optionally, in the embodiment of the present application, Figure 6 ,like Figure 7 As shown, the first body 10 and the second body 13 are connected by a hinge 19 , and the hinge 19 is provided with a first protrusion; the electronic device further includes: a key structure 20 , which is provided on one end of the first body 10 close to the hinge 19 .

[0102] It should be noted that in order to more clearly illustrate the mobile structure in this example, Figure 8 The exploded schematic diagram of the mobile structure of the embodiment of the present application is shown. Figure 8 As shown, the moving structure includes: a driving member 17 provided at the first opening 16 , and a moving member 18 connected to the driving member 17 ; a second sealing member 181 is further provided between the moving member 18 and the first opening 16 .

[0103] Further optionally, in the embodiment of the present application, the driving member 17 may be a motor, and the moving member 18 may be a moving block, wherein the motor may drive the moving block to move in different directions via a screw rod or a gear.

[0104] Further optionally, in an embodiment of the present application, the above-mentioned button structure 20 may include a button and a spring, wherein one end of the spring may be connected to a side of the first body 10 close to the second body 13, and the other end of the spring may be connected to the button.

[0105] The button may specifically be a pressure button, which may be electrically connected to a mainboard of the electronic device.

[0106] In the embodiment of the present application, when the first body 10 and the second body 13 are folded relative to each other, the first protrusion presses the button structure 20 to move the driving member 17 along the first direction.

[0107] Further optionally, combined with Figure 7During the relative folding of the first body 10 and the second body 13, the hinge 19 can rotate clockwise so that the first protrusion can rotate clockwise. When the first body 10 and the second body 13 are folded relative to each other, the first protrusion rotates to a position opposite to the key structure 20 and presses the key structure 20, so that the spring of the key structure 20 can undergo elastic deformation, so that the key of the key structure 20 is triggered, and then the key can send a first signal to the electronic device, and the first signal is used to control the driving member 17 to move along the first direction, so that the driving member 17 moves along the first direction.

[0108] In the embodiment of the present application, during the relative expansion of the first body 10 and the second body 13 , the first protrusion moves away from the button structure 20 , so that the driving member 17 moves along the second direction.

[0109] Further optionally, combined with Figure 7 During the relative expansion of the first body 10 and the second body 13, the hinge 19 can rotate counterclockwise so that the first protrusion can rotate counterclockwise, and then the first protrusion can move away from the key structure 20, so that the spring of the key structure 20 can restore the elastic deformation, so that the key of the key structure 20 is triggered, and then the key can send a second signal to the electronic device, and the second signal is used to control the driving member 17 to move in the second direction, so that the driving member 17 moves in the first direction.

[0110] It can be seen that since a first protrusion can be set on the hinge, the first protrusion and the button structure can be used to determine whether the first body and the second body are relatively folded, so that the driving member can move in different directions. In this way, the accuracy of the electronic device in controlling the movement of the moving member can be improved.

[0111] Example 2:

[0112] In this example, the driving member is taken as an example for description.

[0113] Optionally, in the embodiment of the present application, Figure 9 As shown, the first body 10 and the second body 13 are connected by a hinge 19; the driving member includes: an elastic member 21, one end of the elastic member 21 is arranged at the first opening 16, and the other end of the elastic member 21 is connected to the moving member 18; a second protrusion, the second protrusion is arranged on the hinge 19; a push rod 22, a first end of the push rod 22 is arranged opposite to the moving member 18, and the second end of the push rod 22 is arranged through one end of the first body 10 close to the hinge 19.

[0114] Further optionally, in the embodiment of the present application, a second sealing member is further provided between the moving member 18 and the first opening 16 .

[0115] It should be noted that, in order to more clearly illustrate the driving member in this example, Figure 10 The exploded schematic diagram of the mobile structure of the embodiment of the present application is shown. Figure 10 As shown, the driving member includes: an elastic member 21, one end of which is arranged at the first opening 16, and the other end of the elastic member 21 is connected to the moving member 18; a second protrusion, which is arranged on the hinge 19; a push rod 22, a first end of which is arranged opposite to the moving member 18, and a second end of the push rod 22 is arranged through one end of the first body 10 close to the hinge 19; and a second sealing member 181 is also arranged between the moving member 18 and the first opening 16.

[0116] Figure 11 Schematic diagram of the structure of the mobile structure provided by the embodiment of the present application is shown. Figure 11 As shown, the driving member includes: an elastic member 21, one end of which is arranged at the first opening 16; a second protrusion, which is arranged on the hinge 19; a push rod 22, a first end of which is located at the first opening 16, the first end of which is opposite to the moving member 18, and the second end of which is arranged through one end of the first body 10 close to the hinge 19.

[0117] Further optionally, in the embodiment of the present application, the elastic member 21 may specifically be any one of the following: a spring, elastic rubber, etc.

[0118] In the embodiment of the present application, the above-mentioned moving member 18 can be regarded as the moving end of the moving structure.

[0119] In the embodiment of the present application, when the first body 10 and the second body 13 are folded relative to each other, the second protrusion presses the second end of the push rod 22 to drive the push rod 22 to move along the first direction, so that the first end of the push rod 22 drives the moving member 18 to move along the first direction.

[0120] Further optionally, combined with Figure 11 During the relative folding of the first body 10 and the second body 13, the hinge 19 can rotate clockwise so that the second protrusion can rotate clockwise. When the first body 10 and the second body 13 are folded relative to each other, the second protrusion rotates to a position opposite to the push rod 22 and presses the second end of the push rod 22, so that the push rod 22 can move in the first direction, so that the first end of the push rod 22 can drive the movable member 18 to move in the first direction and cause the elastic member 21 to undergo elastic deformation.

[0121] In the embodiment of the present application, during the relative expansion of the first body 10 and the second body 13 , the second protrusion moves away from the push rod 22 , so that the elastic member 21 drives the moving member 18 to move along the second direction.

[0122] Further optionally, combined with Figure 11 During the relative expansion of the first body 10 and the second body 13, the hinge 19 can rotate counterclockwise so that the second protrusion can rotate counterclockwise to move away from the second end of the push rod 22, so that the elastic member 21 can restore the elastic deformation and drive the moving member 18 to move in the second direction, so that the moving member 18 can contact the first end of the push rod 22 and drive the push rod 22 to move in the second direction.

[0123] It can be seen that since the movable member can be driven to move in different directions by the push rod and the elastic member to control whether the movable member blocks the first opening, and then whether the first rear cavity is connected to the second rear cavity can be quickly controlled, the effect of the electronic device playing audio files through the speaker unit can be quickly improved.

[0124] Example 3:

[0125] Optionally, in the embodiment of the present application, Figure 12 As shown, the first body 10 and the second body 13 are connected by a hinge 19; the moving structure includes: a first gear 23, which is sleeved on the hinge 19; a gear assembly 24, which is arranged at the first opening 16, and the gear assembly 24 is engaged with the first gear 23, and a rotating member 25 is sleeved on the gear assembly 24.

[0126] It should be noted that in order to more clearly illustrate the mobile structure in this example, Figure 13 The exploded schematic diagram of the mobile structure of the embodiment of the present application is shown. Figure 13 As shown, the moving structure includes: a first gear 23, which is sleeved on the hinge 19; a gear assembly 24, which is arranged at the first opening 16 and meshes with the first gear 23, and a rotating member 25 is sleeved on the gear assembly 24.

[0127] Further optionally, in the embodiment of the present application, the gear assembly 24 may include at least one gear, and each gear in the at least one gear is meshed with each other.

[0128] In the embodiment of the present application, the rotating member 25 can be regarded as the moving end of the moving structure.

[0129] Optionally, in an embodiment of the present application, the gear assembly includes: a second gear, which is engaged with the first gear; a third gear, which is engaged with the second gear, and a rotating member is sleeved on the third gear.

[0130] It should be noted that in order to more clearly illustrate the mobile structure, Figure 14 FIG. 1 shows a schematic diagram of the structure of the mobile structure provided by the embodiment of the present application. Figure 14As shown, the gear assembly 24 includes: a second gear 26 , which is engaged with the first gear 23 ; a third gear 27 , which is engaged with the second gear 26 , and a rotating member 25 is sleeved on the third gear 27 .

[0131] In the embodiment of the present application, during the relative folding of the first body 10 and the second body 13 , the hinge 19 drives the gear assembly 24 to rotate along the third direction via the first gear 23 , thereby driving the rotating member 25 to rotate and move away from the first opening 16 .

[0132] Further optionally, in an embodiment of the present application, the third direction may be the same as or opposite to the direction of rotation of the hinge 19 .

[0133] For example, in combination Figure 14 During the relative folding of the first body 10 and the second body 13, the hinge 19 can rotate counterclockwise to drive the first gear 23 to rotate counterclockwise, so that the first gear 23 can drive the second gear 26 to rotate clockwise, so that the second gear 26 can drive the third gear 27 to rotate counterclockwise, so that the third gear 27 can drive the rotating member 25 to rotate counterclockwise to move away from the first opening 16.

[0134] In the embodiment of the present application, during the relative expansion of the first body 10 and the second body 13, the hinge 19 drives the gear assembly 24 to rotate along the fourth direction through the first gear 23, thereby driving the rotating member 25 to rotate and cover the first opening 16; the third direction is different from the fourth direction.

[0135] Further optionally, in an embodiment of the present application, the fourth direction may be opposite to or the same as the rotation direction of the hinge 19 .

[0136] Further optionally, in an embodiment of the present application, the third direction may be opposite to the fourth direction.

[0137] For example, in combination Figure 14 During the relative expansion of the first body 10 and the second body 13, the hinge 19 can rotate clockwise to drive the first gear 23 to rotate clockwise, so that the first gear 23 can drive the second gear 26 to rotate counterclockwise, so that the second gear 26 can drive the third gear 27 to rotate clockwise, so that the third gear 27 can drive the rotating member 25 to rotate clockwise to cover the first opening 16.

[0138] It can be seen that since the rotating member can be driven to move in different directions through the first gear and the gear assembly to control whether the rotating member blocks the first opening, and then whether the first rear cavity is connected to the second rear cavity can be quickly controlled, the effect of the electronic device playing audio files through the speaker unit can be quickly improved.

[0139] The present application embodiment provides an audio signal adjustment method, which is applied to the electronic device in the above embodiment. In order to clearly illustrate the audio signal adjustment method, Figure 15 FIG. 1 shows a flow chart of an audio signal adjustment method provided by an embodiment of the present application. Figure 15 As shown, the audio signal adjustment method provided in the embodiment of the present application may include the following steps 101 to 103.

[0140] Step 101: The electronic device obtains target state information.

[0141] Optionally, in an embodiment of the present application, when the electronic device is in a powered-on state, if the electronic device wants to play an audio file through a speaker unit, the electronic device may obtain target state information.

[0142] Among them, the above-mentioned power-on state is: screen-on state, or screen-off standby state.

[0143] In the embodiment of the present application, the target state information indicates the folding state between the first body and the second body of the current electronic device.

[0144] Optionally, in an embodiment of the present application, the above-mentioned folding state includes: a relatively folded state and a relatively unfolded state.

[0145] Optionally, in an embodiment of the present application, the electronic device may obtain the folding state between the first body and the second body of the current electronic device through a sensor to obtain target state information.

[0146] Further optionally, in an embodiment of the present application, the sensor may detect an angle value between the first body and the second body to obtain a folding state between the first body and the second body of the current electronic device.

[0147] Specifically, if the angle value between the first body and the second body is less than or equal to the preset angle value, the folding state between the first body and the second body of the current electronic device is a relative folding state; if the angle value between the first body and the second body is greater than the preset angle value, the folding state between the first body and the second body of the current electronic device is a relative folding state.

[0148] It can be understood that if the angle value between the first body and the second body is less than or equal to the preset angle value, the target state information indicates that the folding state between the first body and the second body of the current electronic device is a relatively folding state; if the angle value between the first body and the second body is greater than the preset angle value, the target state information indicates that the folding state between the first body and the second body of the current electronic device is a relatively unfolded state.

[0149] Step 102: The electronic device determines target audio parameters corresponding to the target state information.

[0150] Optionally, in an embodiment of the present application, the above-mentioned target audio parameters are parameters related to sound effects.

[0151] Further optionally, in an embodiment of the present application, the target audio parameter may specifically include at least one of the following: a filter parameter, an equalizer parameter, an additional sound effect parameter, a volume parameter, etc.

[0152] Optionally, in an embodiment of the present application, a plurality of preset audio parameters are stored in the electronic device, so that the electronic device can determine a target audio parameter corresponding to the target state information from the plurality of preset audio parameters according to the target state information.

[0153] Further optionally, in an embodiment of the present application, multiple correspondences are stored in the electronic device, each correspondence being a correspondence between a piece of state information and a preset audio parameter, and each piece of state information indicates a folded state between the first and second bodies of the electronic device. Thus, the electronic device can determine, from the multiple pieces of state information, a piece of state information that matches (e.g., is identical to) the target state information, and determine the preset audio parameter corresponding to the piece of state information as the target audio parameter.

[0154] Exemplarily, assuming that multiple preset audio parameters include audio parameter A and audio parameter B, and the target state information indicates that the folding state between the first body and the second body is a relative folding state, then multiple corresponding relationships can be stored in the electronic device, such as corresponding relationship 1 and corresponding relationship 2, wherein the corresponding relationship 1 is the corresponding relationship between state information 1 (the state information 1 indicates that the folding state between the first body and the second body is a relative folding state) and audio parameter A, and the corresponding relationship 2 is the corresponding relationship between state information 2 (the state information 2 indicates that the folding state between the first body and the second body is a relative unfolding state) and audio parameter B, so that the electronic device can determine a state information that matches the target state information from state information 1 and state information 2, that is, state information 1, and determine the audio parameter A corresponding to the state information 1 as the target audio parameter.

[0155] Step 103: The electronic device uses the target audio parameters to adjust the audio signal to be played by the speaker unit of the electronic device.

[0156] Optionally, in an embodiment of the present application, the electronic device may use target audio parameters to adjust audio parameters of the audio signal to be played.

[0157] Further optionally, in an embodiment of the present application, the electronic device can adjust the audio parameters of the audio signal to be played to the target audio parameters; or, the electronic device can increase (or decrease) the parameter value of the audio parameter of the audio signal to be played according to the parameter value of the target audio parameter.

[0158] Optionally, in the embodiment of the present application, after the electronic device adjusts the audio signal to be played by the speaker unit of the electronic device, the electronic device may play the audio signal to be played through the speaker unit.

[0159] In an embodiment of the present application, since the volume of the back cavity of the speaker unit of the electronic device is different when the first body and the second body of the electronic device are in different folding states, the electronic device can determine the target audio parameters based on the target state information indicating the current folding state between the first body and the second body, and use the target audio parameters to adjust the audio signal to be played by the speaker unit to optimize the audio effect of the audio signal to be played.

[0160] In the audio signal adjustment method provided in the embodiment of the present application, an electronic device can obtain target state information indicating the current folding state between the first body and the second body of the electronic device, and determine corresponding target audio parameters based on the target state information, so that the electronic device can use the target audio parameters to adjust the audio signal to be played by the speaker unit of the electronic device. Since the electronic device can determine different audio parameters when the first body and the second body are in different folding states, and use the different audio parameters to adjust the audio signal to be played by the speaker unit, the audio effect of the audio signal played by the speaker unit when the first body and the second body are in different folding states can be improved.

[0161] The audio signal adjustment method provided in the embodiment of the present application can be executed by an audio signal adjustment device. In the embodiment of the present application, the audio signal adjustment device provided in the embodiment of the present application is described by taking the audio signal adjustment device executing the audio signal adjustment method as an example.

The processing module 73 is configured to adjust the audio signal to be played by the speaker unit of the audio signal adjustment device 70 using the target audio parameters determined by the determination module 72.

[0164] The audio signal adjustment device provided in the embodiment of the present application can determine different audio parameters when the first body and the second body are in different folding states, and use the different audio parameters to adjust the audio signal to be played by the speaker unit. Therefore, the audio effect of the audio signal played by the speaker unit when the first body and the second body are in different folding states can be improved.
