As shown in fig. 3, when the area of the display area of the flexible screen of the electronic device is the largest, the speaker module 61 is no longer limited by the fixing bracket 31, and the speaker assembly 611 is driven by the lifting mechanism to continuously rise until the lower end of the movable upper housing 6112 abuts against the upper end of the fixed upper housing 6113 (the sealing vibration reduction member 616 is pressed by the first and second skirting portions), and at this time, a sealed rear sound cavity 6182 in a developed state is formed between the lower end surface of the movable upper housing 6112 and the bottom surface of the second housing 22.
Under the condition that the area of the display area of the flexible screen of the electronic device needs to be reduced, under the driving of the driving assembly, the second shell 22 and the moving support 32 move towards the direction close to the first shell 21 and the fixed support 31 under the driving of the second end of the flexible screen, after the fixed support 31 contacts with the lower shell 6111, the fixed support 31 applies pressure to the loudspeaker module 61, the loudspeaker assembly 611 moves downwards under the guiding of the arc-shaped surface and the guide post 611 of the lifting mechanism, and the back sound cavity returns to the state with the minimum volume.
In the process of switching between the unfolding state and the folding state of the electronic device, the volume of the rear sound cavity of the speaker module 61 of the electronic device is changed, the space between the movable support 32 and the second shell 22 is fully utilized, and the volume of the rear sound cavity is adjusted under the condition that the thickness of the electronic device is not increased, so that the low-frequency resonant frequency of the speaker module 61 is adjusted, and the low-frequency sensitivity and the low-frequency performance of the speaker module 61 are improved.
As shown in fig. 5, an embodiment of the present application further provides an audio parameter adjusting method, where the method is applied to the electronic device described above, and the method includes:

Specifically, the rotation angle can be determined according to the number of pulse signals of the driving motor in the driving assembly and the step angle of the driving motor, and the moving distance of the moving support can be further determined according to the rotation angle, specifically, according to a formula: θ = θ s Obtaining the rotation angle by x A, wherein theta is the rotation angle and theta is s The step angle, A is the number of pulse signals.
as mentioned above, during the operation of the driving motor, the driving motor drives the second section of the flexible screen, the moving bracket 32, the second housing 22, and other components to move, so that the moving distance of the scroll screen assembly can be determined according to the rotation angle of the driving motor, and the volume of the back sound cavity can be determined.
As can be seen from the foregoing, the surface of the lower housing 6111 of the speaker module has an arc surface, and when the scroll screen assembly is in a step state, if only the arc surface contacts the fixing support 31, the speaker assembly 611 will rise or fall under the driving of the lifting mechanism, and the volume of the back sound cavity will change.
In addition, it should be noted that, in the process of determining the volume of the back sound cavity according to the moving distance, the volume of the back sound cavity may be determined based on the moving distance determined by the state (contracted state, expanded state) of the scroll screen assembly of the electronic device before the driving motor operates and the rotation angle of the driving motor, or the volume of the back sound cavity may be determined based on the rotation direction of the output shaft of the driving motor (for example, in the case that the scroll screen assembly is switched from the expanded state to the contracted state, the scroll screen assembly rotates in a first preset direction, and in the case that the scroll screen assembly is switched from the contracted state to the expanded state, the scroll screen assembly rotates in a second preset direction, and the first preset direction and the second preset direction are opposite directions) and the movement distance determined by the rotation angle.
The step may specifically be adjusting the audio parameter according to a pre-configured corresponding relationship between the volume of the back sound cavity and the audio parameter. Specifically, the corresponding relationship may be preset by an electronic device manufacturer, or may be preset by a user according to a use habit of the user.
The audio parameters are parameters related to sound effects, such as: filter parameters, equalizer parameters, additional sound effect parameters, volume level parameters, and the like.
According to the audio parameter adjusting method, firstly, the moving distance of a moving support is obtained; secondly, determining the volume of the rear sound cavity according to the moving distance; thirdly, adjusting the audio parameters according to the volume of the rear sound cavity; therefore, real-time adjustment of the audio parameters according to the volume of the rear sound cavity is realized to optimize the playing effect, so that the sound effect of the loudspeaker module is optimized according with the requirements of users; in addition, the whole power consumption and the temperature rise level of the mobile phone can be properly reduced by adjusting the audio parameters in real time according to the volume of the rear sound cavity, and the satisfaction of a user and the service life of the electronic equipment are effectively improved.
As an optional implementation manner, in step 501, acquiring a moving distance of the moving support includes:
acquiring the moving distance of the moving support according to the rotating angle of a driving motor for driving the electronic equipment to stretch;
the step can be specifically that the expansion length variation quantity when the flexible screen drives the movable support to rotate is determined according to the rotation angle of the output shaft and the parameters of a transmission assembly of the electronic equipment, and the expansion length (movement distance) is determined according to the initial state (the expansion state and the contraction state) of the flexible screen; specifically, when the scroll screen assembly is switched from the contracted state to the expanded state, the expanded length is the length variation, and when the scroll screen assembly is switched from the expanded state to the contracted state, the expanded length is a difference between the length of the flexible screen in the expanded state and the length variation.
As an optional implementation manner, step 502, determining the volume of the back sound cavity according to the moving distance includes:
the method comprises the following steps: under the condition that the moving distance is determined to be smaller than or equal to a first preset distance, determining the volume of the rear sound cavity to be a first preset volume;
in this step, the first preset distance may be a length of the planar portion of the lower housing 6111 along the telescopic direction of the scroll screen assembly as shown in fig. 1.
Step two: determining the volume of the rear sound cavity as a second preset volume under the condition that the moving distance is greater than or equal to the second preset distance;
in this step, the second preset distance may be the length of the lower housing 6111 along the telescopic direction of the scroll screen assembly.
Step three: under the condition that the movement distance is determined to be larger than a first preset distance and smaller than a second preset distance, determining the volume of the rear sound cavity according to the movement change; the first preset distance is smaller than the second preset distance, and the first preset volume is smaller than the second preset volume.
Specifically, the volume of the rear sound cavity may be determined according to V = sxh, where V is the volume of the rear sound cavity, S is the area of the lower end face of the movable upper housing 6113, and h is the distance between the lower end face of the movable upper housing 6113 and the bottom surface of the second housing 22.
