As shown in fig. 6, fig. 6 is a first flowchart of a play control method provided in the embodiment of the present application, where the flowchart may include:

101. and acquiring telescopic parameters of the telescopic display screen.

As described above, the electronic device to which the play control method provided by the present application is applied includes the retractable display screen, and the retractable display screen can be extended or retracted. The expansion parameter may include parameters of the expandable display screen when expanding or contracting, such as expansion distance (expansion distance or contraction distance), expansion speed (expansion speed or contraction speed), expansion direction (expansion direction or contraction direction), and the like. The telescopic distance refers to a telescopic distance of the telescopic display screen in a corresponding telescopic direction when the telescopic display screen is telescopic. For example, in the case of vertical expansion, the expansion distance of the retractable display screen, that is, the distance that the retractable display screen increases or decreases in the longitudinal direction; in the case of lateral expansion, the expansion distance of the expandable display screen, i.e., the distance the expandable display screen increases or decreases in the lateral direction. For example, when the retractable display screen extends from the position A1 to the position A2, the retractable distance of the retractable display screen is the distance between the position A1 and the position A2. For another example, when the retractable display screen is retracted from the position A3 to the position A4, the retractable distance of the retractable display screen is the distance between the position A3 and the position A4. The stretching speed refers to the stretching speed of the stretchable display screen in the corresponding stretching direction when the stretchable display screen stretches. For example, assuming that the retractable display screen is extended at a speed V1, the retractable speed is V1. For example, assuming that the retractable display screen is retracted at a speed V2, the retraction speed is V2. The telescopic direction of the telescopic display screen is the telescopic direction of the telescopic display screen. For example, if the retractable display screen extends horizontally to the right, the retractable direction of the retractable display screen is horizontally to the right; if the telescopic display screen transversely contracts leftwards, the telescopic direction of the telescopic display screen is transversely leftwards; if the retractable display screen is retracted longitudinally upwards, the retractable direction of the retractable display screen is longitudinally upwards.

For example, after the electronic device plays the multimedia file according to the user operation, if the user controls the extension or the contraction of the retractable display screen, the electronic device may obtain the expansion parameter of the retractable display screen.

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

102. And playing and controlling the multimedia file according to the expansion parameters.

The multimedia file may include a video file or an audio file, among others.

In this embodiment, after obtaining the scaling parameter of the scalable display screen, the electronic device may perform play control on the multimedia file according to the scaling parameter, for example, control a volume of playing the multimedia file, a play progress of the multimedia file, a play speed of the multimedia file, pause playing the multimedia file, and the like.

For example, the scaling parameter may include a scaling distance, and the electronic device may determine to adjust the volume according to the scaling distance. Then, the electronic device can adjust the playing volume of the multimedia file according to the adjusted volume. The telescopic distance is positively correlated with the adjusted volume, namely the longer the telescopic distance is, the larger the adjusted volume is, the shorter the telescopic distance is, and the smaller the adjusted volume is.

For example, the electronic device may preset a preset mapping relationship between the telescopic distance and the adjusted volume. The preset mapping relationship may include a one-to-one correspondence between a telescopic distance and an adjusted volume. The preset mapping relationship may include a one-to-one correspondence relationship between the telescopic distance interval and the adjusted volume. After the telescopic distance is obtained, the electronic device can determine to adjust the volume according to the telescopic distance and the preset mapping relation. Then, the electronic device can obtain the current playing volume of the multimedia file, and determine the target playing volume according to the current playing volume and the adjusted volume. After the target playing volume is obtained, the electronic equipment can adjust the playing volume of the multimedia file to the target playing volume. When the telescopic display screen is extended, the sum of the current playing volume and the adjusted volume is used as the target playing volume. And when the telescopic display screen is contracted, taking the difference between the current playing volume and the adjusted volume as the target playing volume. In some embodiments, the telescopic display screen is extended or retracted to correspond to the sum of the current playback volume and the adjusted volume as the target playback volume. In other embodiments, the extension or contraction of the retractable display screen corresponds to the difference between the current playback volume and the adjusted volume being the target playback volume.

For another example, the scaling parameter may include a scaling distance, and the electronic device may determine the target playing speed according to the scaling distance. Subsequently, the electronic device may adjust the play speed of the multimedia file to the target play speed. The stretching distance is positively correlated with the playing speed, namely the longer the stretching distance is, the faster the playing speed is, the shorter the stretching distance is, and the slower the playing speed is.

For example, the electronic device may preset a preset mapping relationship between the telescopic distance and the playing speed. The preset mapping relationship may include a one-to-one correspondence between a telescopic distance and a play speed. The preset mapping relationship may include a one-to-one correspondence relationship between the telescopic distance interval and the playing speed. After the telescopic distance is obtained, the electronic device can determine the target playing speed according to the telescopic distance and the preset mapping relation. Then, the electronic device can adjust the playing speed of the multimedia file to the target playing speed.

In the embodiment of the application, the expansion parameters of the expandable display screen are obtained; according to the telescopic parameters, the multimedia file is played and controlled, so that the multimedia file can be played and controlled by controlling the telescopic display screen to stretch out or shrink, the multimedia file does not need to be played and controlled by sliding on the display screen with fingers, and the display screen is prevented from being shielded.

In some embodiments, the scaling parameter includes a scaling distance, and the playing control of the multimedia file according to the scaling parameter may include:

(1) Determining an adjusting step length according to the telescopic distance;

(2) And adjusting the playing progress of the multimedia file according to the adjustment step length.

The adjustment step length is the length of the playing progress of the multimedia file adjusted each time. For example, assuming that the playing rate of the multimedia file is 20 minutes of playing and the adjustment step size is 5 seconds, after the playing rate of the multimedia file is adjusted once according to the adjustment step size, the playing rate of the multimedia file is 5 seconds of playing 20 minutes or 55 seconds of playing 19 minutes. The telescopic distance is positively correlated with the adjustment step length. That is, the longer the telescopic distance, the longer the adjustment step length; the shorter the telescopic distance, the shorter the adjustment step length.

For example, after the telescopic distance of the telescopic display screen is acquired, the electronic device may determine the adjustment step length according to the telescopic distance. After the adjustment step length is determined, the electronic device may adjust the playing progress of the multimedia file according to the adjustment step length, for example, perform fast forward or fast backward processing on the multimedia file according to the adjustment step length.

In some embodiments, the electronic device can fast forward the multimedia file in accordance with the adjustment step size when the retractable display screen is extended. When the telescopic display screen is contracted, the electronic equipment can perform fast-rewinding processing on the multimedia file according to the adjusting step length.

In other embodiments, the electronic device fast-forwards the multimedia file according to the adjustment step, whether the retractable display screen is extended or retracted. Or whether the telescopic display screen extends or contracts, the electronic equipment performs fast-rewinding processing on the multimedia file according to the adjusting step length.

In some embodiments, a touch button may be disposed on a side of the electronic device, and the touch button may be embedded in the electronic device. The electronic equipment can receive the touch operation of a user through the touch key, so that whether the multimedia file is subjected to fast forward processing or fast backward processing is judged 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 that the multimedia file is fast-forwarded, and when the sliding direction of the sliding operation is a second preset direction, it is determined that the multimedia file is fast-backed. Then, when the user wants to fast forward the multimedia file, the user may slide the finger on the touch key toward the first preset direction to trigger the electronic device to fast forward the multimedia file, and then the electronic device may obtain the telescopic distance of the telescopic display screen, determine an adjustment step length according to the telescopic distance, and adjust the playing progress of the multimedia file according to the adjustment step length. The first preset direction and the second preset direction are two different directions. The first preset direction and the second preset direction may be set according to practical situations, and are not particularly limited herein.

In some embodiments, determining the adjustment step size according to the telescopic distance may include:

(1) Acquiring a preset mapping relation between the telescopic distance and the adjustment step length;

(2) And determining the adjustment step length according to the telescopic distance and the preset mapping relation.

For example, the electronic device may preset a preset mapping relationship between the telescopic distance and the adjustment step length. The preset mapping relationship may include a one-to-one correspondence relationship between the telescopic distance interval and the adjustment step length. The preset mapping relationship may also include a one-to-one correspondence relationship between the telescopic distance and the adjustment step length.

After the telescopic distance of the telescopic display screen is acquired, the electronic device can acquire the preset mapping relation. Then, the electronic device may determine an adjustment step length according to the telescopic distance and the preset mapping relationship. For example, assuming that the telescopic distance is M1, and the telescopic distance M1 corresponds to the adjustment step length R1, the electronic device may determine that the adjustment step length is R1 according to the telescopic distance M1 and the preset mapping relationship.

In some embodiments, determining the adjustment step size according to the telescopic distance may include:

and when the telescopic distance is greater than the preset distance, determining the adjustment step length according to the telescopic distance.

In some cases, for example, when the retractable display screen extends to a certain extent, if the user accidentally touches the retractable display screen, the retractable display screen may also be retracted by a certain distance, and at this time, the user does not intend to play and control the multimedia file, so that, in order to avoid the occurrence of an error response, the electronic device may determine whether the retractable distance is greater than the preset distance after acquiring the retractable distance, and if the retractable distance is greater than the preset distance, the electronic device may determine the adjustment step length according to the retractable distance. If the telescopic distance is less than or equal to the preset distance, the electronic equipment does not need to process. The preset distance may be set according to actual conditions, and is not particularly limited herein. For example, the preset distance may be 3mm, 5mm, or 7mm, and so on.

In some embodiments, the scaling parameter includes a scaling speed, and the playing control of the multimedia file according to the scaling parameter may include:

(1) Determining an adjusting step length according to the stretching speed;

(2) And adjusting the playing progress of the multimedia file according to the adjustment step length.

Wherein, the stretching speed is positively correlated with the adjusting step length. That is, the faster the expansion and contraction speed, the faster the adjustment step length; the slower the telescoping speed, the slower the adjustment step length.

For example, after the expansion speed of the expandable display screen is acquired, the electronic device may determine the adjustment step length according to the expansion speed. After the adjustment step length is determined, the electronic device may adjust the playing progress of the multimedia file according to the adjustment step length, for example, control the multimedia file to fast forward or fast backward according to the adjustment step length, so that the user may control the adjustment step length for adjusting the playing progress of the multimedia file by controlling the expansion speed of the scalable display screen.

For example, after the expansion speed of the expandable display screen is obtained, the electronic device may determine the adjustment step length according to the expansion speed. After the adjustment step length is determined, the electronic device may adjust the playing progress of the multimedia file according to the adjustment step length, for example, perform fast forward or fast backward processing on the multimedia file according to the adjustment step length.

In some embodiments, the electronic device can fast forward the multimedia file in accordance with the adjustment step size when the scalable display screen is extended. When the telescopic display screen is contracted, the electronic equipment can perform fast-rewinding processing on the multimedia file according to the adjusting step length.

In other embodiments, the electronic device fast-forwards the multimedia file according to the adjustment step size whether the retractable display screen is extended or retracted. Or, whether the telescopic display screen is extended or contracted, the electronic equipment performs fast backward processing on the multimedia file according to the adjusting step length.

In some embodiments, a touch button may be disposed on a side of the electronic device, and the touch button may be embedded in the electronic device. The electronic equipment can receive the touch operation of a user through the touch key, so that whether the multimedia file is subjected to fast forward processing or fast backward processing is judged 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 that the multimedia file is fast-forwarded, and when the sliding direction of the sliding operation is a second preset direction, it is determined that the multimedia file is fast-backed. Then, when the user wants to fast forward the multimedia file, the user may slide the finger on the touch key toward the first preset direction to trigger the electronic device to fast forward the multimedia file, and then the electronic device may obtain the stretching speed of the stretchable display screen, determine an adjustment step length according to the stretching speed, and adjust the playing progress of the multimedia file according to the adjustment step length. The first preset direction and the second preset direction are two different directions. The first preset direction and the second preset direction may be set according to actual situations, and are not particularly limited herein.

In some embodiments, the telescoping parameters further include a telescoping distance, and determining the adjustment step size according to the telescoping speed may include:

and when the telescopic distance is greater than the preset distance, determining the adjustment step length according to the telescopic speed.

In some cases, for example, when the scalable display screen extends to a certain degree, if the user touches the scalable display screen carelessly, also can make the scalable display screen shrink a certain distance, user's intention is not to play control to the multimedia file this moment, therefore, in order to avoid the condition of wrong response, when the scalable display screen is flexible, electronic equipment can acquire the flexible distance of scalable display screen earlier, and judge whether flexible distance is greater than the preset distance, if flexible distance is greater than the preset distance, then electronic equipment can acquire the flexible speed of scalable display screen, and according to flexible speed, confirm to adjust the step length. If the telescopic distance is less than or equal to the preset distance, the electronic equipment does not need to process the telescopic distance. The preset distance may be set according to actual conditions, and is not particularly limited herein. For example, the preset distance may be 3mm, 5mm, or 7mm, and so on.

In some embodiments, determining the adjustment step size based on the telescoping speed may include:

(1) Acquiring a preset mapping relation between the stretching speed and the adjustment step length;

(2) And determining the adjustment step length according to the stretching speed and the preset mapping relation.

For example, the electronic device may preset a preset mapping relationship between the scaling speed and the adjustment step length. The preset mapping relationship may include a one-to-one correspondence relationship between the expansion speed interval and the adjustment step length. The preset mapping relationship may also include a one-to-one correspondence relationship between the stretching speed and the adjustment step length.

After the stretching speed of the stretchable display screen is obtained, the electronic device may obtain the preset mapping relationship. Then, the electronic device may determine an adjustment step length according to the stretching speed and the preset mapping relationship. For example, assuming that the stretching speed is V1, and the stretching speed V1 corresponds to the adjustment step length R1, the electronic device may determine that the adjustment step length is R1 according to the stretching speed V1 and the preset mapping relationship.

In some embodiments, the scaling parameter includes a scaling distance, and playing control of the multimedia file according to the scaling parameter may include:

(1) Determining the target playing progress of the multimedia file according to the telescopic distance;

(2) And adjusting the playing progress of the multimedia file to the target playing progress.

And when the multimedia file needs to be controlled to fast forward, the target playing progress = the adjustment progress + the current playing progress. For example, if the current playing schedule of the electronic device is played for 5 minutes, and the adjustment schedule is 2 minutes, the target playing schedule is played for 7 minutes. When the multimedia file needs to be controlled to fast backward, the target playing progress = the current playing progress-the adjusting progress. For example, if the current playing schedule of the electronic device is 5 minutes played, and the adjustment schedule is 2 minutes, the target playing schedule is 3 minutes played.

For example, when the multimedia file needs to be controlled to fast forward or fast backward, the user may control the retractable display screen to extend or retract, so that the electronic device may determine the adjustment progress according to the retraction distance. Then, the electronic device can determine a target playing progress of the multimedia file according to the adjustment progress and the current playing progress of the multimedia file. After the target playing progress is determined, the electronic equipment 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 telescopic distance of the telescopic display screen.

In some embodiments, the scaling parameters further include a scaling direction, and determining a target playing progress of the multimedia file according to the scaling distance may include:

and determining the target playing progress of the multimedia file according to the telescopic distance and the telescopic direction.

For example, the telescopic direction of the telescopic display screen is the extension direction to correspondingly control the fast forward of the multimedia file, and the telescopic direction of the telescopic display screen is the contraction direction to correspondingly control the fast backward of the multimedia file, so that when the user controls the extension of the display screen, the electronic equipment can determine that the telescopic direction is the extension direction, and then the electronic equipment can determine the adjustment progress according to the telescopic distance; then, the electronic device can calculate the sum of the adjustment progress and the current playing progress to obtain the target playing progress. The electronic equipment can adjust the playing progress of the multimedia file to the target playing progress; when the user controls the display screen to shrink, the electronic equipment can determine that the stretching direction is the shrinking direction, and then the electronic equipment can determine the adjusting progress according to the stretching distance; then, the electronic device can calculate the difference between the current playing progress and the adjusting progress to obtain the target playing progress. The electronic equipment can adjust the playing progress of the multimedia file to the target playing progress.

In some embodiments, the electronic device takes the sum of the current playback progress and the adjusted progress as the target playback progress regardless of whether the retractable display screen is extended or retracted. Or, whether the telescopic display screen extends or contracts, the electronic equipment takes the difference between the current playing progress and the adjusting progress as the target playing progress.

In other embodiments, a touch button may be disposed on a side of the electronic device, and the touch button may be embedded in the electronic device. The electronic equipment can receive the touch operation of a user through the touch key, so that whether the multimedia file is subjected to fast forward processing or fast backward processing is judged 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 that the multimedia file is fast-forwarded, and when the sliding direction of the sliding operation is a second preset direction, it is determined that the multimedia file is fast-backed. Then, when the user wants to fast forward the multimedia file, the user may slide a finger on the touch key in a first preset direction to trigger the electronic device to fast forward the multimedia file, and then the electronic device may obtain a telescopic distance of the telescopic display screen, and determine an adjustment progress according to the telescopic distance. The electronic equipment can take the sum of the adjusting progress and the current playing progress as a target playing progress, and adjust the playing progress of the multimedia file to the target playing progress. The first preset direction and the second preset direction are two different directions. The first preset direction and the second preset direction may be set according to practical situations, and are not particularly limited herein.

In some embodiments, the scaling parameters include a scaling speed and a scaling track, and the playing control of the multimedia file according to the scaling parameters may include:

and when the stretching speed is higher than the preset speed and the stretching track is matched with the preset track, stopping playing the multimedia file.

The preset speed and the preset trajectory may be set according to actual conditions, and are not limited herein.

For example, in the playing process of the multimedia file, the user may continuously control the retractable display screen to extend for a certain distance at a retracting speed greater than the preset speed, and then retract for a certain distance at a retracting speed greater than the preset speed, so that the electronic device detects that the retracting speed is greater than the preset speed, and the retracting track is matched with the preset track, and then the electronic device stops playing the multimedia file.

It can be understood that the play control method of the present application is applied to play control of a multimedia file by obtaining a scaling parameter of a scalable display screen when the scalable display screen is extended or retracted during a playing process of the multimedia file, and then, a display size of a content of the multimedia file played on the scalable display screen is adaptively adjusted along with the extension or retraction of the scalable display screen during the extension or retraction of the scalable display screen.

Referring to fig. 7, fig. 7 is a second process diagram of a play control method according to an embodiment of the present application, where the process may include:

201. and acquiring the telescopic distance of the telescopic display screen.

As described above, the electronic device to which the play control method provided by the present application is applied includes the retractable display screen, and the retractable display screen can be extended or retracted. The telescopic distance refers to a telescopic distance of the telescopic display screen in a corresponding telescopic direction when the telescopic display screen is telescopic. For example, in the case of vertical expansion, the expansion distance of the retractable display screen, i.e. the distance that the retractable display screen increases or decreases in the longitudinal direction; in the case of lateral expansion, the expansion distance of the expandable display screen, i.e., the distance the expandable display screen increases or decreases in the lateral direction. For example, when the retractable display screen extends from the position A1 to the position A2, the retractable distance of the retractable display screen is the distance between the position A1 and the position A2. For another example, when the retractable display screen is retracted from the position A3 to the position A4, the retractable distance of the retractable display screen is the distance between the position A3 and the position A4.

For example, during the process of playing the multimedia file by the electronic device, the user may control the retractable display screen to extend or retract, so that the electronic device may obtain the retractable distance of the retractable display screen.

202. And when the telescopic distance is greater than the preset distance, acquiring a preset mapping relation between the telescopic distance and the adjustment step length.

Wherein the telescopic distance is positively correlated with the adjustment step length. That is, the longer the telescopic distance, the faster the adjustment step length; the shorter the telescopic distance, the slower the adjustment step length.

For example, the electronic device may preset a preset mapping relationship between the telescopic distance and the adjustment step length. The preset mapping relationship may include a one-to-one correspondence relationship between the telescopic distance interval and the adjustment step length. The preset mapping relationship may also include a one-to-one correspondence relationship between the telescopic distance and the adjustment step length.

In this embodiment, after the telescopic distance is obtained, the electronic device may determine whether the telescopic distance is greater than a preset distance. When the telescopic distance is greater than the preset distance, the electronic device can acquire the preset mapping relation.

203. And determining the adjustment step length according to the telescopic distance and the preset mapping relation.

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

204. And adjusting the playing progress of the multimedia file according to the adjusting step length.
