Wherein, if the dynamic sound field following enhancement instruction is not received, it is assumed that the user does not need to experience the dynamic sound field during the expansion and contraction process, so that the user can directly control the The type of audio is stereo audio or mixed audio.

Further, judging whether to perform sound field enhancement according to the final distance between the first casing and the second casing specifically includes: when performing sound field enhancement according to the final distance, determining a final sound field enhancement parameter according to the final distance, and controlling the speaker 104 according to The final sound field enhancement parameter plays audio; when the sound field enhancement is not performed according to the final distance, it is used to control the speaker to play audio according to the default stereo parameters.

When the sound field is enhanced according to the final distance, the controller 110 will acquire the final distance, and the second housing 1024 can be kept at any position relative to the first housing 1022. When the second housing 1024 and the first housing 1022 When the distance between them does not change, the current distance can be considered as the final distance, so that the final sound field enhancement parameters will be acquired according to the final distance and the speaker 104 will be controlled to play. And when there is no sound field enhancement, it is only necessary to simply control the speaker 104 to play the audio according to the default stereo parameters.

Further, in the direction perpendicular to the moving direction of the flexible screen 106, the speakers 104 are arranged at both ends of the first casing 1022, and the speakers 104 are arranged at both ends of the second casing 1024, the audio playing method further includes: determining the flexible screen The display orientation of 106, when the display orientation is landscape display, the speaker 104 for playing audio is determined according to the landscape orientation of the flexible screen 106.

When the scroll screen is stretched, the inner sound hole leaks out, and the sound is emitted through the inner sound hole; when the scroll screen is not stretched, the inner sound hole The sound outlet coincides with the outer sound outlet, and the sound passes through the inner sound outlet, then passes through the outer sound outlet, and then is emitted. The second speaker unit is sealed with the inner sound hole by the second sealing foam. Soft silica gel is added around the sound hole inside the second speaker. The first function of the silica gel is to prevent friction and collision between the handle shell and the fixed shell when the scroll screen is retracted; the second is to prevent dust from entering the gap here; the third is to realize Sealing of the inner sound hole and the outer sound hole of the second speaker.

Due to the limitation of the shape of the scroll screen, the fixed shell and the handle shell are both curved surfaces, so the shape of the sound cavity of the first speaker and the sound cavity of the second speaker is changeable. When the space is sufficient, it can be a normal three-dimensional shape. When the space is limited , as shown in Figure 3, one side is in a curved state, and the arc surface can be the front chamber or the rear chamber, and the specific form of stacking is mainly used to distinguish whether it is used as the front and rear chambers.

The control logic of the controller to play audio on the device is as follows:

When the scrolling screen is not stretched or the stretched distance<x (x is the stretching distance threshold set in advance, that is, the stretching distance of the first speaker and the second speaker), at this time because the first speaker and the second speaker The distance between the speakers is relatively short. It is meaningless for the two speakers to be divided into left and right channels to play, and it cannot reflect the advantages of stereo. Therefore, it can be set. At this time, the audio signal is processed according to mixing, and then sent to the first speaker and the second speaker at the same time. The two speakers play, that is, the sound of the first speaker and the second speaker are exactly the same, so as to achieve the effect of increasing the loudness.

When the scroll screen is not stretched or the stretching distance is ≥ x, the audio signal stream is not mixed, and is transmitted to the first speaker and the second speaker according to the left and right channels, so that the first speaker can play the left channel sound. The second speaker plays the stereo effect of the right channel sound.

Specifically, an embodiment of an audio playback method is shown in Figure 15, including: step S101: play music; step S102: judge the state of the whole machine; If the machine is in the motion state, execute step S1042: maintain the previous playing state; if the whole machine is in the default state, execute step S1046: play the mixed audio signal. During the stretching or retracting process of the whole machine while playing music, the stretching or long distance will pass the x threshold. At this time, in order to prevent sudden changes in the signal, you can set the playback mode to maintain the output of the previous state, that is, if When the mixed audio signal or stereo signal is played, the mixed audio signal or stereo signal is played all the time until the stretching and retracting state of the whole machine is stable and the player is paused, and then the state judgment is performed again whether to switch the playback mode.

As shown in Figure 16, the audio playback method includes: step S202: judge the music playing status of the whole machine; stretched distance), as the two speakers stretch farther and farther away, the distance and direction of the human ear relative to the speaker have changed. However, the sound field heard by the human ear is constantly weakening. Therefore, a sound field adjustment function is required to meet the needs of different stretching distances, and users can obtain a better sound field surround experience.

Set the playback mode to, when the playback distance of the two speakers ≥ x, turn on the stereo mode plus the sound field enhancement mode, and set the complete stretching distance as y, divide the distance between x and y into n intervals, Different sound field enhancement parameters are called in each interval to ensure that users can be provided with good stereo sound in different stretching states.

a. First, detect the relationship between the stretching state of the whole machine and x at this time. If the stretching state of the whole machine is less than x at this time, execute step S203: play the mixed signal; if ≥ x, execute step S204: play Stereo signal.

b. If the stretching state of the whole machine is greater than or equal to x at this time, the stereo signal is played, and step S206 is performed at this time: whether to enable dynamic sound field enhancement follow-up.

c. If it is not enabled at this time, go to step S208: whether to use sound field enhancement according to the final stretched state of the whole machine, if this function is turned on, go to step S211: play fixed-point sound field enhancement parameters according to the final stretched state of the screen, That is, to detect which distance range the final stretched distance of the speaker falls in, which set of sound effect enhancement parameters will be called, and to use the sound field enhancement parameter 2 if the final stretching distance is determined to be in the x+1 state; If the sound field enhancement is used in the stretched final state, it is considered that it is not necessary to enable the parameter of sound field enhancement, and step S213 is performed: the default stereo effect is sufficient.

d. If the dynamic sound field enhancement follow is turned on at this time, start to execute step S210: judge the screen status of the whole machine, that is, the distance between the two speakers at this time, and execute step S212: determine different sound field enhancement parameters according to the distance, and play accordingly Audio, dynamically switch the speaker sound field enhancement parameters at this time, providing users with a good stereo sound field effect at all times.
