Further, the method further comprises the following steps: and a controller 110 electrically connected to the speaker 104, the controller 110 being configured to control the speaker 104 to play audio.

By providing the controller 110 electrically connected to the speaker 104, the speaker 104 can be controlled to play audio, and in particular, the controller 110 can control different speakers 104 to play audio according to different play modes according to different positions of the speaker 104.

Further, the present application also provides an audio playing method, including: judging whether a loudspeaker of the flexible screen plays audio or not, and generating a judging result; and when the judgment result is yes, controlling a loudspeaker in the first shell and/or a loudspeaker in the second shell to play audio according to the telescopic state of the flexible screen.

Specifically, when controlling the speaker 104 to play audio, it is first determined whether the speaker 104 is playing audio, if audio is being played, the telescopic state of the flexible screen 106 is obtained, and different speakers 104 are controlled to operate according to different telescopic states, where the telescopic state is not limited to two states, i.e. the contracted state and the expanded state, and the relative distance between the first housing 1022 and the second housing 1024 may be any distance.

Further, the method further comprises the following steps: determining a distance between the first housing and the second housing; and when the distance is greater than the distance threshold, controlling the loudspeaker to play the stereo audio, otherwise, controlling the loudspeaker to play the mixed audio.

Specifically, the distance between the first housing 1022 and the second housing 1024 can be detected by setting a distance sensor electrically connected to the controller 110, when the distance is larger, that is, the distance is determined, and when the distance is larger than the distance threshold, the distance between the speaker 104 in the first housing 1022 and the speaker 104 in the second housing 1024 can be considered larger, at this time, if a single audio mixing is played, the playing effect is poor, and the stereo audio can be directly played.

The distance threshold value can be determined according to a conventional distance setting generated by the stereo audio, and can also be determined according to a setting of a user or a manufacturer.

Further, the method further comprises the following steps: determining whether a dynamic sound field following enhancement instruction is received; if so, determining sound field enhancement parameters according to the distance to control the loudspeaker to play the audio, otherwise, judging whether sound field enhancement is carried out according to the final distance between the first shell and the second shell.

Because the space between the first housing 1022 and the second housing 1024 can be manually stretched and contracted by the user, when playing audio, the controller 110 can also determine whether to receive the dynamic sound field following enhancement command, if so, the sound field enhancement parameters need to be determined according to the real-time distance between the first housing 1022 and the second housing 1024, it can be understood that the position between the first housing 1022 and the second housing 1024 changes, the speaker 104 located on the two will also change accordingly, and for different users, each user has a size adapted to the palm shape or the use habit of the user, so that different sound field enhancement parameters can be determined according to different distances, so as to improve the audio-visual experience of the user.

If the dynamic sound field following enhancement instruction is not received, the default user does not need to experience the dynamic sound field in the telescopic process at this time, so that the type of the audio can be controlled to be stereo or mixed according to the distance between the first housing 1022 and the second housing 1024.

Further, judging whether sound field enhancement is performed according to a final distance between the first casing and the second casing specifically includes: when sound field enhancement is performed according to the final distance, determining final sound field enhancement parameters according to the final distance, and controlling the loudspeaker 104 to play audio according to the final sound field enhancement parameters; and when the sound field enhancement is not performed according to the final distance, the method is used for controlling the loudspeaker to play the audio according to the default stereo parameters.

When the sound field enhancement is performed according to the final distance, the controller 110 obtains the final distance, the second housing 1024 may be maintained at any position with respect to the first housing 1022, and when the distance between the second housing 1024 and the first housing 1022 does not change, the current distance may be considered as the final distance, so that the final sound field enhancement parameter may be obtained according to the final distance and the speaker 104 may be controlled to play. When the sound field enhancement is not needed, the speaker 104 is simply controlled to play the audio according to the default stereo parameters.

Further, in a direction perpendicular to the moving direction of the flexible screen 106, the speakers 104 are disposed at two ends of the first housing 1022, and the speakers 104 are disposed at two ends of the second housing 1024, and the audio playing method further includes: the display direction of the flexible screen 106 is determined, and when the display direction is the horizontal screen display, the speaker 104 for playing the audio is determined according to the horizontal screen direction of the flexible screen 106.

Speakers 104 are respectively disposed at two ends of the first housing 1022 and two ends of the second housing 1024, and different speakers 104 for playing audio can be determined according to different display directions of the flexible screen 106, and it can be understood that the flexible screen 106 can be divided into a horizontal screen and a vertical screen according to different usage habits, and when the flexible screen 106 is displayed by the horizontal screen, the corresponding speakers 104 can be determined to play audio.

In another embodiment, when the display direction is a portrait display, the controller 110 is configured to determine the speaker 104 that plays audio according to the telescopic state of the flexible screen 106.

As shown in fig. 14, the present application further provides an embodiment of an electronic device 200, including a housing 210 and a screen assembly, where the screen assembly is disposed on the housing 210 so as to implement basic functions of communication, display, etc. of the electronic device 200, and on this basis, the housing 210 may provide a certain protection effect for the screen assembly, and since the electronic device 200 includes the screen assembly, the embodiment has the beneficial effects of any one of the foregoing embodiments, which will not be described herein again.

The lower cover plate (namely the end cover plate) of the whole device is provided with a first loudspeaker sound outlet and a second loudspeaker sound outlet respectively, wherein the sound outlet channel of the first loudspeaker is unique, and the opening from the single body to the whole shell is sealed by a first sealing foam (namely a sealing piece).

The sound outlet of the second loudspeaker is divided into an inner sound outlet and an outer sound outlet, when the scroll screen is stretched, the inner sound outlet leaks outwards, and sound is emitted through the inner sound outlet; when the scroll screen is not stretched, the inner sound outlet hole coincides with the outer sound outlet hole, and sound passes through the inner sound outlet hole, passes through the outer sound outlet hole and then is emitted. The second loudspeaker unit is sealed with the sound outlet hole at the inner side through a second sealing foam. Soft silica gel is added at the periphery of the sound outlet hole at the inner side of the second loudspeaker, and the silica gel has the function of preventing the handle shell from friction collision with the fixed shell when the scroll screen is retracted; secondly, preventing gap dust entering from occurring; and thirdly, sealing the inner sound outlet and the outer sound outlet of the second loudspeaker.

Because the shape of the scroll screen is limited, the fixed shell and the handle shell are both curved surfaces, so that the shape of the sound cavity of the first loudspeaker and the shape of the sound cavity of the second loudspeaker are changeable, when the space is enough, the sound cavity can be in a normal three-dimensional shape, when the space is limited, one surface can be in a curved arc state as shown in fig. 3, the circular arc surface can be a front cavity or a rear cavity, and whether the sound cavity is used as the front cavity and the rear cavity is mainly distinguished in a stacked specific form.

The control logic of the controller for playing the audio to the device is as follows:

when the scroll screen is not stretched or the stretched distance is less than x (x is a stretched distance threshold set in advance, namely the stretched distance between the first loudspeaker and the second loudspeaker), at this time, because the distance between the first loudspeaker and the second loudspeaker is relatively short, the meaning of the two loudspeakers in the left and right sound channel playing is not great, and the advantage of stereo cannot be represented, so that the audio signal can be set, and then the audio signal is processed according to the mixing sound and is sent to the first loudspeaker and the second loudspeaker for playing at the same time, namely the sound of the first loudspeaker and the sound of the second loudspeaker are completely consistent, and the effect of increasing the loudness is achieved.

When the scroll screen is not stretched or the stretched distance is not less than x, audio signal flow is not subjected to mixing processing and is respectively transmitted to the first loudspeaker and the second loudspeaker according to the left channel and the right channel, so that the first loudspeaker plays left channel sound, and the second loudspeaker plays stereophonic effect of right channel sound.

Specifically, as shown in fig. 15, an embodiment of an audio playing method includes: step S101: playing music; step S102: judging the state of the whole machine; if the whole machine is in a stretched state, step S1048 is executed: playing the binaural signal, and executing step S1042 if the whole machine is in a motion state: maintaining the last play state, and executing step S1046 if the complete machine is in the default state: playing the mixed sound signal. In the process of stretching or retracting while playing music, the stretching or multi-session distance can pass through the x threshold, and at this time, in order to prevent abrupt change of signals, the playing mode can be set to maintain the output of the previous state, that is, if the mixed signal or the stereo signal is played, the mixed signal or the stereo signal is always played until the stretching and retracting state of the whole machine is stable and after the player pauses, the state judgment is performed again to judge whether to switch the playing mode.

As shown in fig. 16, the audio playing method includes: step S202: judging the music playing state of the whole machine; when the stretching distance of the scroll screen is more than or equal to x (x is a stretching distance threshold value set in advance, namely the stretching distance of the first loudspeaker and the second loudspeaker), along with the increasing distance of the two loudspeakers, the distance and the direction of the human ear relative to the loudspeakers are changed, and at the moment, if a set of stereo parameters are adopted, the distinguishing degree of the left and right channels is improved, but the sound field heard by the human ear is continuously weakened, so that a sound field adjusting function is needed, and a user can obtain better sound field surrounding experience under different stretching distance states.

When the play distance between two loudspeakers is more than or equal to x, starting a stereo mode and a sound field enhancement mode, setting the complete stretching distance as y, dividing the distance between x and y into n sections, and calling different sound field enhancement parameters for each section to ensure that good stereo can be provided for users in different stretching states.

a. Firstly, detecting the relation between the stretching state of the whole machine and x, and if the stretching state of the whole machine is smaller than x, executing step S203: playing the mixed sound signal; if not less than x, executing step S204: and playing the stereo signal.

b. If the stretching state of the whole machine is not less than x at this time, playing a stereo signal, and executing step S206 at this time: whether dynamic sound field enhancement following is turned on.

c. If not, step S208 is executed: if the sound field enhancement is needed according to the stretching final state of the whole machine, if the function is started, step S211 is executed: playing fixed-point sound field enhancement parameters according to a final screen stretching state, namely detecting a distance of a loudspeaker which is finally stretched and falls in which distance interval, calling which group of sound effect enhancement parameters, and detecting that the final stretching distance is fixed in an x+1 state, and using sound field enhancement parameters 2; if the sound field enhancement is not needed according to the final stretching state of the whole machine, the parameters of the sound field enhancement are not required to be started, and the step S213 is executed: default stereo effect is sufficient.

d. If dynamic sound field enhancement following is turned on at this time, step S210 is started: judging the screen state of the whole machine, namely the distance between the two speakers, and executing step S212: and determining different sound field enhancement parameters according to the distance, playing the audio according to the different sound field enhancement parameters, and dynamically switching the sound field enhancement parameters of the loudspeaker at the moment to provide a good stereophonic sound field effect for the user at any time.
