[0023] Reference will now be made to the drawings, wherein like numerals refer to like components throughout. The application will be described in relation to the embodiments thereof, which are by way of illustration only, and are not to be construed in any way limiting of the application.

[0024] Embodiments of the present application provide a playback control method, a playback control device, a storage medium and an electronic device. The execution subject of the playback control method can be the electronic device provided by the embodiments of the present application, and the playback control device can be realized in the form of hardware or software.

[0025] It should be noted that the electronic device provided by the present application is configured with a telescopic display screen, that is, the telescopic display screen can be stretched and can be retracted. The telescopic display screen is made of flexible material, so that it can be bent, curled and folded, etc., so as to realize the telescopic purpose. Based on the telescopic display screen, the electronic device can increase the visual area of the telescopic display screen by stretching the telescopic display screen, improve the display effect, and also can reduce the visual area of the telescopic display screen by retracting the telescopic display screen, reduce the power consumption.

[0026] Exemplarily, referring to Figures 1 to 3 , the electronic device 100 includes a housing assembly 10, a telescopic display screen 30, a driving member 50 and a driving mechanism 70. The housing assembly 10 is a hollow structure; the driving member 50, the driving mechanism 70 and the camera 90 and other components can be arranged in the housing assembly 10. It can be understood that the electronic device 100 of the embodiments of the present application includes but is not limited to mobile terminals such as mobile phones, tablets and other portable electronic devices. In this paper, the electronic device 100 is taken as a mobile phone as an example for description.

[0027] In the present embodiment, the housing assembly 10 includes a first housing 12 and a second housing 14, and the first housing 12 and the second housing 14 can move relatively. Specifically, in the present embodiment, the first housing 12 and the second housing 14 are connected in sliding mode, that is, the second housing 14 can slide relative to the first housing 12.

[0028] Specifically, referring to Figure 4 and Figure 5 , the first housing 12 and the second housing 14 jointly form a receiving space 16. The receiving space 16 can be used to place components such as the driving member 50, the camera 90 and the driving mechanism 70. The housing assembly 10 can further include a rear cover 18, and the rear cover 18, the first housing 12 and the second housing 14 jointly form the receiving space 16.

[0029] The driving member 50 is arranged in the second housing 14, one end of the retractable display screen 30 is arranged in the first housing 12, the retractable display screen 30 passes around the driving member 50, and the other end of the retractable display screen is arranged in the accommodating space 16, so that part of the retractable display screen is hidden in the accommodating space 16, and the part of the retractable display screen 30 hidden in the accommodating space 16 can not be lighted. The first housing 12 and the second housing 14 are relatively far away, and the retractable display screen 30 can be unfolded by the driving member 50, so that more retractable display screens 30 are exposed outside the accommodating space 16. The retractable display screen 30 exposed outside the accommodating space 16 is lighted, so that the display area presented by the electronic device 100 becomes larger.

[0030] The driving member 50 can be a rotating shaft structure with teeth 52 on the outside, and the retractable display screen 30 is connected to the driving member 50 by meshing or the like. When the first housing 12 and the second housing 14 are relatively far away, the part of the retractable display screen 30 meshed with the driving member 50 is moved and unfolded by the driving member 50.

[0031] It can be understood that the driving member 50 can also be a round shaft without teeth 52. When the first housing 12 and the second housing 14 are relatively far away, the part of the retractable display screen 30 wound on the driving member 50 is stretched by the driving member 50, so that more retractable display screens 30 are exposed outside the accommodating space 16 and are in a flat state. Specifically, the driving member 50 is rotatably arranged in the second housing 14, and when the retractable display screen 30 is gradually stretched, the driving member 50 can rotate with the movement of the retractable display screen 30. In other embodiments, the driving member 50 can be fixed on the second housing 14, and the driving member 50 has a smooth surface. When the retractable display screen 30 is stretched, the driving member 50 is in slidable contact with the retractable display screen 30 through the smooth surface.

[0032] When the first housing 12 and the second housing 14 are relatively close, the retractable display screen can be retracted by the driving member 50. Alternatively, the electronic device 100 further comprises a reset member (not shown), one end of the retractable display screen accommodated in the accommodating space 16 is connected to the reset member, and when the first housing 12 and the second housing 14 are relatively close, the reset member drives the retractable display screen 30 to reset, so that part of the retractable display screen 30 is retracted into the accommodating space 16.

[0033] In the embodiment, the driving mechanism 70 can be arranged in the accommodating space 16, the driving mechanism 70 can be connected to the second housing 14, and the driving mechanism 70 is used to drive the second housing 14 to move away from the first housing 12, thereby driving the retractable display screen assembly 30 to stretch. It can be understood that the driving mechanism 70 can also be omitted, and the user can directly move the first housing and the second housing relative to each other by manual or the like.

[0034] Based on the electronic device provided above in this application, this application further provides a playback control method applied to the electronic device.

[0035] like Figure 6 As shown, Figure 6 This is a schematic diagram of the first process of the playback control method provided in an embodiment of the present application. The process may include:

[0036] 101. Obtain the retractable parameters of the retractable display screen.

[0037] As described above, the electronic device to which the playback control method provided in this application is applied includes a retractable display screen that can be extended or retracted. The retractable parameters may include parameters for the extension or retraction of the retractable display screen, such as the retractable distance (extension distance or retraction distance), the retractable speed (extension speed or retraction speed), the retractable direction (extension direction or retraction direction), and so on. The retractable distance refers to the distance the retractable display screen extends and retracts in the corresponding retractable direction when it is extended and retracted. For example, in the case of vertical retraction, the retractable distance of the retractable display screen is the distance the retractable display screen increases or decreases in the vertical direction; in the case of horizontal retraction, the retractable distance of the retractable display screen is the distance the retractable display screen increases or decreases in the horizontal direction. For example, when the retractable display screen extends from position A1 to position A2, the retractable distance of the retractable display screen is the distance between positions A1 and A2. For another example, when the retractable display screen retracts from position A3 to position A4, the retractable distance of the retractable display screen is the distance between positions A3 and A4. The retractable speed refers to the speed at which the retractable display screen extends and retracts in the corresponding retractable direction when it is extended and retracted. For example, if the retractable display screen extends at a speed of V1, then the retractable speed is V1. For example, if the retractable display screen retracts at a speed of V2, then the retractable speed is V2. The retractable direction of the retractable display screen is the direction in which the retractable display screen retracts. For example, if the retractable display screen extends horizontally to the right, then the retractable direction of the retractable display screen is horizontally to the right; if the retractable display screen retracts horizontally to the left, then the retractable direction of the retractable display screen is horizontally to the left; if the retractable display screen retracts vertically upward, then the retractable direction of the retractable display screen is vertically upward.

[0038] For example, after the electronic device plays a multimedia file according to a user operation, if the user controls the retractable display screen to expand or contract, the electronic device can obtain the retractable parameters of the retractable display screen.

[0039] For example, when the retractable display screen is extended, the electronic device may obtain the extension distance of the retractable display screen.

[0040] 102. Control the playback of the multimedia file according to the scaling parameter.

[0041] The multimedia file can include a video file or an audio file, etc.

[0042] In this embodiment, after the scalable parameter of the scalable display screen is acquired, the electronic device can control the multimedia file according to the scalable parameter, such as controlling the volume of the multimedia file, the playing progress of the multimedia file, the playing speed of the multimedia file, pausing the multimedia file, etc.

[0043] For example, the scalable parameter can include a scalable distance, and the electronic device can determine an adjustment volume according to the scalable distance. Then, the electronic device can adjust the playing volume of the multimedia file according to the adjustment volume. The scalable distance is positively correlated with the adjustment volume, that is, the longer the scalable distance, the greater the adjustment volume, and the shorter the scalable distance, the smaller the adjustment volume.

[0044] For example, the electronic device can pre-set a preset mapping relationship between the scalable distance and the adjustment volume. The preset mapping relationship can include a one-to-one corresponding relationship between the scalable distance and the adjustment volume. The preset mapping relationship can include a one-to-one corresponding relationship between a scalable distance interval and an adjustment volume. After the scalable distance is acquired, the electronic device can determine the adjustment volume according to the scalable distance and the preset mapping relationship. Then, the electronic device can acquire the current playing volume of the multimedia file, and determine a target playing volume according to the current playing volume and the adjustment volume. After the target playing volume is obtained, the electronic device can adjust the playing volume of the multimedia file to the target playing volume. When the scalable display screen is stretched, the sum of the current playing volume and the adjustment volume is taken as the target playing volume. When the scalable display screen is contracted, the difference between the current playing volume and the adjustment volume is taken as the target playing volume. In some embodiments, the stretching or the contraction of the scalable display screen corresponds to taking the sum of the current playing volume and the adjustment volume as the target playing volume. In other embodiments, the stretching or the contraction of the scalable display screen corresponds to taking the difference between the current playing volume and the adjustment volume as the target playing volume.

[0045] For another example, the scalable parameter can include a scalable distance, and the electronic device can determine a target playing speed according to the scalable distance. Then, the electronic device can adjust the playing speed of the multimedia file to the target playing speed. The scalable distance is positively correlated with the playing speed, that is, the longer the scalable distance, the faster the playing speed, and the shorter the scalable distance, the slower the playing speed.

[0046] For example, the electronic device can pre-set a preset mapping relationship between the stretching distance and the play speed. The preset mapping relationship can include a one-to-one correspondence between the stretching distance and the play speed. The preset mapping relationship can include a one-to-one correspondence between the stretching distance interval and the play speed. After obtaining the stretching distance, the electronic device can determine the target play speed according to the stretching distance and the preset mapping relationship. Then, the electronic device can adjust the play speed of the multimedia file to the target play speed.

[0047] In the embodiments of the present application, the stretching parameter of the stretchable display screen is obtained, and the multimedia file is played and controlled according to the stretching parameter, so that the multimedia file can be played and controlled by controlling the stretching or shrinking of the stretchable display screen, without the need to slide the finger on the display screen to play and control the multimedia, thereby avoiding the blocking of the display screen.

[0048] In some embodiments, the stretching parameter includes the stretching distance, and the play control of the multimedia file according to the stretching parameter can include:

[0049] (1) determining the adjustment step according to the stretching distance;

[0050] (2) adjusting the play progress of the multimedia file according to the adjustment step.

[0051] The adjustment step is how much the play progress of the multimedia file is adjusted each time. For example, assuming that the play progress of the multimedia file is 20 minutes played, and the adjustment step is 5 seconds, then after adjusting the play progress of the multimedia file according to the adjustment step once, the play progress of the multimedia file is 20 minutes 5 seconds played or 19 minutes 55 seconds played. The stretching distance is positively related to the adjustment step. That is, the longer the stretching distance, the longer the adjustment step; the shorter the stretching distance, the shorter the adjustment step.

[0052] For example, after obtaining the stretching distance of the stretchable display screen, the electronic device can determine the adjustment step according to the stretching distance. After determining the adjustment step, the electronic device can adjust the play progress of the multimedia file according to the adjustment step, such as fast-forwarding or fast-rewinding the multimedia file according to the adjustment step.

[0053] In some embodiments, when the stretchable display screen is stretched, the electronic device can fast-forward the multimedia file according to the adjustment step. When the stretchable display screen is shrunk, the electronic device can fast-rewind the multimedia file according to the adjustment step.

[0054] In other embodiments, whether the stretchable display screen is stretched or shrunk, the electronic device fast-forwards the multimedia file according to the adjustment step. Or, whether the stretchable display screen is stretched or shrunk, the electronic device fast-rewinds the multimedia file according to the adjustment step.

[0055] In some embodiments, the electronic device can be provided with a touch key on the side of the electronic device. The touch key can be built-in the electronic device. The electronic device can receive a touch operation of a user through the touch key, and determine whether to fast forward or fast rewind the multimedia file according to the touch operation. For example, assume that the touch operation includes a sliding operation. When the sliding direction of the sliding operation is a first preset direction, it is determined to fast forward the multimedia file. When the sliding direction of the sliding operation is a second preset direction, it is determined to fast rewind the multimedia file. Then, when the user wants to fast forward the multimedia file, the user can slide a finger on the touch key in the first preset direction to trigger the electronic device to fast forward the multimedia file. Subsequently, the electronic device can obtain the extension distance of the extendable display screen, determine the adjustment step according to the extension distance, and adjust the playing progress of the multimedia file according to the adjustment step. The first preset direction and the second preset direction are different directions. The first preset direction and the second preset direction can be set according to actual conditions, which are not limited here.

[0056] In some embodiments, determining the adjustment step according to the extension distance can include:

[0057] (1) obtaining a preset mapping relationship between the extension distance and the adjustment step;

[0058] (2) determining the adjustment step according to the extension distance and the preset mapping relationship.

[0059] For example, the electronic device can pre-set a preset mapping relationship between the extension distance and the adjustment step. The preset mapping relationship can include a one-to-one correspondence between the extension distance interval and the adjustment step. The preset mapping relationship can also include a one-to-one correspondence between the extension distance and the adjustment step.

[0060] After obtaining the extension distance of the extendable display screen, the electronic device can obtain the preset mapping relationship. Then, the electronic device can determine the adjustment step according to the extension distance and the preset mapping relationship. For example, assume that the extension distance is M1, the extension distance M1 corresponds to the adjustment step R1, and the electronic device can determine the adjustment step to be R1 according to the extension distance M1 and the preset mapping relationship.

[0061] In some embodiments, determining the adjustment step according to the extension distance can include:

[0062] When the extension distance is greater than a preset distance, the adjustment step is determined according to the extension distance.

[0063] In some cases, for example, when the stretchable display screen is stretched to a certain extent, if the user accidentally touches the stretchable display screen, the stretchable display screen will also be retracted by a certain distance, at this time, the user's intention is not to control the multimedia file to be played, therefore, to avoid the case of incorrect response, the electronic device can first determine whether the stretching distance is greater than a preset distance after obtaining the stretching distance, if the stretching distance is greater than the preset distance, the electronic device can determine the adjustment step according to the stretching distance. If the stretching distance is less than or equal to the preset distance, the electronic device can not be processed. Wherein, the preset distance can be set according to the actual situation, which is not limited here. For example, the preset distance can be 3mm, 5mm or 7mm, etc.

[0064] In some embodiments, the stretching parameter includes a stretching speed, and the playing control of the multimedia file according to the stretching parameter can include:

[0065] (1) determining the adjustment step according to the stretching speed;

[0066] (2) adjusting the playing progress of the multimedia file according to the adjustment step.

[0067] Wherein, the stretching speed is positively correlated with the adjustment step. That is to say, the faster the stretching speed, the faster the adjustment step; the slower the stretching speed, the slower the adjustment step.

[0068] For example, after obtaining the stretching speed of the stretchable display screen, the electronic device can determine the adjustment step according to the stretching speed. After determining the adjustment step, the electronic device can adjust the playing progress of the multimedia file according to the adjustment step, such as controlling the multimedia file to fast forward or fast backward according to the adjustment step, so that the user can control the adjustment step of adjusting the playing progress of the multimedia file by controlling the stretching speed of the stretchable display screen.

[0069] For example, after obtaining the stretching speed of the stretchable display screen, the electronic device can determine the adjustment step according to the stretching speed. After determining the adjustment step, the electronic device can adjust the playing progress of the multimedia file according to the adjustment step, such as controlling the multimedia file to fast forward or fast backward according to the adjustment step, so that the user can control the adjustment step of adjusting the playing progress of the multimedia file by controlling the stretching speed of the stretchable display screen.

[0070] In some embodiments, when the stretchable display screen is stretched, the electronic device can fast forward the multimedia file according to the adjustment step. When the stretchable display screen is retracted, the electronic device can fast backward the multimedia file according to the adjustment step.

[0071] In some other embodiments, whether the stretchable display screen is stretched or retracted, the electronic device fast forwards the multimedia file according to the adjustment step. Or, whether the stretchable display screen is stretched or retracted, the electronic device fast backwards the multimedia file according to the adjustment step.

[0072] In some embodiments, the side of the electronic device can be provided with a touch key which can be built-in the electronic device. The electronic device can receive a touch operation of a user through the touch key, and determine whether to fast forward or fast rewind the multimedia file according to the touch operation. For example, assuming that the touch operation includes a sliding operation, when the sliding direction of the sliding operation is a first preset direction, it is determined to fast forward the multimedia file, and when the sliding direction of the sliding operation is a second preset direction, it is determined to fast rewind the multimedia file. Then, when the user wants to fast forward the multimedia file, the user can slide on the touch key with a finger towards the first preset direction to trigger the electronic device to fast forward the multimedia file, and then the electronic device can obtain the expansion speed of the scalable display screen, determine the adjustment step according to the expansion speed, and adjust the playing progress of the multimedia file according to the adjustment step. The first preset direction and the second preset direction are different directions. The first preset direction and the second preset direction can be set according to actual conditions, which are not limited here.

[0073] In some embodiments, the expansion parameter further includes an expansion distance, and determining the adjustment step according to the expansion speed can include:

[0074] When the expansion distance is greater than a preset distance, the adjustment step is determined according to the expansion speed.

[0075] In some cases, for example, when the scalable display screen is expanded to a certain extent, if the user accidentally touches the scalable display screen, the scalable display screen will also be retracted by a certain distance. At this time, the user's intention is not to control the playing of the multimedia file. Therefore, to avoid the situation of false response, when the scalable display screen is expanded or retracted, the electronic device can first obtain the expansion distance of the scalable display screen, and determine whether the expansion distance is greater than a preset distance. If the expansion distance is greater than the preset distance, the electronic device can obtain the expansion speed of the scalable display screen, and determine the adjustment step according to the expansion speed. If the expansion distance is less than or equal to the preset distance, the electronic device can not be processed. The preset distance can be set according to actual conditions, which is not limited here. For example, the preset distance can be 3mm, 5mm or 7mm, etc.

[0076] In some embodiments, determining the adjustment step according to the expansion speed can include:

[0077] (1) obtaining a preset mapping relationship between the expansion speed and the adjustment step;

[0078] (2) determining the adjustment step according to the expansion speed and the preset mapping relationship.

[0079] For example, the electronic device can pre-set a preset mapping relationship between the stretching speed and the adjustment step. The preset mapping relationship can include a one-to-one correspondence between the stretching speed interval and the adjustment step. The preset mapping relationship can also include a one-to-one correspondence between the stretching speed and the adjustment step.

[0080] After obtaining the stretching speed of the stretchable display screen, the electronic device can obtain the preset mapping relationship. Then, the electronic device can determine the adjustment step according to the stretching speed and the preset mapping relationship. For example, assuming that the stretching speed is V1, the stretching speed V1 corresponds to the adjustment step R1, the electronic device can determine the adjustment step R1 according to the stretching speed V1 and the preset mapping relationship.

[0081] In some embodiments, the stretching parameter includes a stretching distance, and the playing control of the multimedia file according to the stretching parameter can include:

[0082] (1) determining a target playing progress of the multimedia file according to the stretching distance;

[0083] (2) adjusting the playing progress of the multimedia file to the target playing progress.

[0084] Wherein, when it is needed to control the multimedia file to fast forward, the target playing progress = the adjustment progress + the current playing progress. For example, assuming that the current playing progress of the electronic device is 5 minutes played, and the adjustment progress is 2 minutes, the target playing progress is 7 minutes played. When it is needed to control the multimedia file to fast backward, the target playing progress = the current playing progress - the adjustment progress. For example, assuming that the current playing progress of the electronic device is 5 minutes played, and the adjustment progress is 2 minutes, the target playing progress is 3 minutes played.

[0085] For example, when it is needed to control the multimedia file to fast forward or fast backward, the user can control the stretchable display screen to stretch or shrink, so that the electronic device can determine the adjustment progress according to the stretching distance. Then, the electronic device can determine the target playing progress of the multimedia file according to the adjustment progress and the current playing progress of the multimedia file. After determining the target playing progress, the electronic device can adjust the playing progress of the multimedia file to the target playing progress, so that the user can control the playing progress of the multimedia file by controlling the stretching distance of the stretchable display screen.

[0086] In some embodiments, the stretching parameter further includes a stretching direction, and the determining of the target playing progress of the multimedia file according to the stretching distance can include:

[0087] determining the target playing progress of the multimedia file according to the stretching distance and the stretching direction.

[0088] For example, when the user controls the display screen to stretch, the electronic device can determine that the stretching direction is the stretching direction, and then determine the adjustment progress according to the stretching distance. The electronic device can calculate the sum of the adjustment progress and the current play progress to obtain the target play progress. The electronic device can adjust the play progress of the multimedia file to the target play progress. When the user controls the display screen to contract, the electronic device can determine that the stretching direction is the contracting direction, and then determine the adjustment progress according to the stretching distance. The electronic device can calculate the difference between the current play progress and the adjustment progress to obtain the target play progress. The electronic device can adjust the play progress of the multimedia file to the target play progress.

[0089] In some embodiments, the electronic device calculates the sum of the current play progress and the adjustment progress as the target play progress regardless of whether the display screen stretches or contracts. Alternatively, the electronic device calculates the difference between the current play progress and the adjustment progress as the target play progress regardless of whether the display screen stretches or contracts.

[0090] In some embodiments, the electronic device can be provided with a touch key on the side. The touch key can be built-in. The electronic device can receive a touch operation of the user through the touch key, and determine whether to fast forward or fast rewind the multimedia file according to the touch operation. For example, the touch operation can include a sliding operation. When the sliding direction of the sliding operation is a first preset direction, the electronic device determines to fast forward the multimedia file. When the sliding direction of the sliding operation is a second preset direction, the electronic device determines to fast rewind the multimedia file. When the user wants to fast forward the multimedia file, the user can slide the finger on the touch key in the first preset direction to trigger the electronic device to fast forward the multimedia file. Then, the electronic device can obtain the stretching distance of the display screen, and determine the adjustment progress according to the stretching distance. The electronic device can calculate the sum of the adjustment progress and the current play progress as the target play progress, and adjust the play progress of the multimedia file to the target play progress. The first preset direction and the second preset direction are different directions. The first preset direction and the second preset direction can be set according to actual conditions, which are not limited herein.

[0091] In some embodiments, the stretching parameter includes a stretching speed and a stretching trajectory. The play control of the multimedia file according to the stretching parameter can include:

[0092] When the stretching speed is greater than a preset speed, and the stretching trajectory matches a preset trajectory, the play of the multimedia file is stopped.

[0093] The preset speed and the preset track can be set according to actual conditions, and are not specifically limited here.

[0094] For example, during the playing of a multimedia file, a user can control the scalable display screen to stretch a certain distance at a stretching speed greater than the preset speed and then to contract a certain distance at a contracting speed greater than the preset speed for a plurality of times, such as twice, so that the electronic device detects that the stretching speed is greater than the preset speed and the stretching track matches the preset track, and then the electronic device stops playing the multimedia file.

[0095] It can be understood that the playing control method of the present application is applied to playing control of a multimedia file by acquiring the stretching parameter of the scalable display screen when the scalable display screen is stretched or contracted, so that the display size of the content of the multimedia file played on the scalable display screen is adaptively adjusted when the scalable display screen is stretched or contracted.

[0096] Please refer to Figure 7 , Figure 7 FIG. 2 is a second flowchart of the playing control method provided by the present application, and the flowchart can include the following steps.

[0097] 201. Acquire the stretching distance of the scalable display screen.

[0098] As described above, the electronic device to which the playing control method of the present application is applied includes a scalable display screen, and the scalable display screen can be stretched or contracted. The stretching distance refers to the distance of the scalable display screen in the corresponding stretching direction when the scalable display screen is stretched or contracted. For example, in the case of vertical stretching, the stretching distance of the scalable display screen refers to the distance of the scalable display screen in the vertical direction; in the case of horizontal stretching, the stretching distance of the scalable display screen refers to the distance of the scalable display screen in the horizontal direction. For example, when the scalable display screen is stretched from position A1 to position A2, the stretching distance of the scalable display screen is the distance between position A1 and position A2. For another example, when the scalable display screen is contracted from position A3 to position A4, the stretching distance of the scalable display screen is the distance between position A3 and position A4.

[0099] For example, during the playing of a multimedia file by the electronic device, a user can control the scalable display screen to stretch or contract, so that the electronic device can acquire the stretching distance of the scalable display screen.

[0100] 202. When the stretching distance is greater than the preset distance, acquire the preset mapping relationship between the stretching distance and the adjustment step.

[0101] The stretching distance and the adjustment step are positively correlated. That is, the longer the stretching distance, the faster the adjustment step; the shorter the stretching distance, the slower the adjustment step.

[0102] For example, the electronic device can pre-set a preset mapping relationship between the telescopic distance and the adjustment step. The preset mapping relationship can include a one-to-one correspondence between the telescopic distance interval and the adjustment step. The preset mapping relationship can also include a one-to-one correspondence between the telescopic distance and the adjustment step.

[0103] In this embodiment, after the telescopic distance is obtained, the electronic device can determine whether the telescopic distance is greater than the preset distance. When the telescopic distance is greater than the preset distance, the electronic device can obtain the preset mapping relationship.

[0104] 203. Determine the adjustment step according to the telescopic distance and the preset mapping relationship.

[0105] In this embodiment, after the preset mapping relationship is obtained, the electronic device can determine the adjustment step according to the telescopic distance and the preset mapping relationship. For example, assuming that the telescopic distance is M1, the telescopic distance M1 corresponds to the adjustment step R1, and the electronic device can determine the adjustment step to be R1 according to the telescopic distance M1 and the preset mapping relationship.

[0106] 204. Adjust the playing progress of the multimedia file according to the adjustment step.

[0107] In this embodiment, after the adjustment step is determined, the electronic device can adjust the playing progress of the multimedia file according to the adjustment step. For example, assuming that the adjustment step is R1, the electronic device can adjust the playing progress of the multimedia file according to the adjustment step R1.
