In some embodiments, the first sound sensor converts the collected ambient sound into an ambient sound signal and transmits the ambient sound signal to the central processing unit, and the central processing unit analyzes the received ambient sound parameter to determine the current ambient condition.

The common environmental sound grading mode is as follows: 0-20 decibel, silence; 20-40 decibels, quiet; 40-60 decibels, normal indoor talk; 60-70 decibels, noisy and damaged nerves; 70-90 db, loud, damaged nerve cells; 90-100 db, loud, and impaired hearing. In some embodiments, the ambient sound level of the ambient sound may be obtained according to the decibel value of the ambient sound and the first correspondence table; the first corresponding relation table comprises corresponding relations between decibel values and environmental sound levels. For example, the first table of correspondences may rank the ambient sounds as D1, D2, D3, and in one embodiment, the contents of the first table of correspondences are as follows:

ambient sound level	Decibel value
		D1	0-30 decibel
D2	30-60 decibels

In some embodiments, the bending parameters of the flexible screen can be adjusted according to the environmental sound parameters and the second corresponding relation table; the second corresponding relation table comprises the corresponding relation between the environmental sound parameter and the bending parameter.

For example, the second mapping table may divide the bending parameters into 2 steps: bend C1, bend C2. Wherein:

bending C1: referring to fig. 4a, two ends of the flexible screen are bent inwards, and each sub-parameter in the bending parameter C is adjusted, so that the flexible screen forms a semi-open type sound cavity;

bending C2: referring to fig. 4b, after a semi-open sound cavity is formed by bending C1, the bending curvature of the flexible screen is further increased, so that the flexible screen forms a closed sound cavity.

In one embodiment, the contents of the second correspondence table are as follows:

ambient sound parameter	Bending parameter
		D1	C1
D2	C2
		D3	C1

Table 2: second corresponding relation table

The corresponding bending parameters can be obtained according to the environment sound parameters and the second corresponding relation table, the central processing unit can send corresponding control signals to the flexible screen control chip, and the flexible screen control chip drives the flexible screen to be bent correspondingly according to the control signals.

In example 1A, by using the echo principle, in a sound cavity formed by bending a flexible screen, not only audio emitted by a speaker but also sound reflected and refracted after encountering the flexible screen wall (flexible screen) are mixed together, so that the original sound is enhanced and a sound mixing effect is formed, and the sound quality effect is better when an audio file is played. In addition, the flexible screen shell is bent, so that the sound cavity formed by bending can be utilized to reduce the sound quality loss of audio in open space playing, and the discomfort brought to a listener by ultrahigh frequency sound is improved. For example, reflected sound can be increased by bending the flexible screen into a semi-closed sound cavity (bending C1), harsh high-frequency and ultrahigh-frequency sound can be lost, the tone color is softer, the listening effect of direct sound is increased, and the tone quality is clearer; the reverberation function can be increased by bending the flexible screen into a closed sound cavity (bending C2), and the sound is decorated.

s210, collecting environmental sound;

s220, analyzing the environmental sound to obtain corresponding environmental sound parameters;

and S230, adjusting the vibration parameter of the flexible screen according to the environmental sound parameter so as to adjust the audio playing effect.

Step S210 is the same as step S110 in example 1A, and reference may be made to the description of step S110; step S220 corresponds to step S120 in example 1A, and reference may be made to the description of step S120 above; and will not be described in detail herein.

In step S230, the vibration parameter of the flexible screen is adjusted according to the environmental sound parameter to adjust the audio playing effect.

In some embodiments, the flexible screen control chip may receive a control signal from the central processing unit, and drive the flexible screen to vibrate according to the control signal. For example, when playing an audio file, the central processor matches the environmental sound parameter with the vibration parameter: firstly, acquiring the corresponding relation between each note to be output and the screen vibration frequency from a memory; secondly, determining corresponding vibration parameters according to different environment sound parameters and a third relation corresponding table; and thirdly, sending a corresponding control signal to the flexible screen control chip by the central processing unit so as to drive the flexible screen to vibrate. A flexible screen shaking parameter V is preset in the memory, wherein V is taken from the initials of Vibrate, and the flexible screen shaking parameter V includes but is not limited to: the corresponding relation of the vibration amplitude of the flexible screen, the audio note and the vibration frequency of the screen.

In some embodiments, the vibration parameter of the flexible screen can be adjusted according to the environmental sound parameter and the third corresponding relation table; the third corresponding relation table comprises the corresponding relation between the environmental sound parameter and the vibration parameter.

For example, the third correspondence table may divide the flexible screen shaking parameter into 4 steps: no vibration V0, vibration V1, vibration V2, and vibration V3. Wherein the content of the first and second substances,

shockless V0: the flexible screen is in a static and non-vibration state;

the vibration V1 is the screen vibration amplitude of the audio note between the bass Do — treble Si, which is the lowest vibration amplitude (base vibration amplitude);

the vibration V2 is twice the vibration amplitude of the vibration V1, that is, V2 is V1 × 2;

the vibration V3 is three times the vibration amplitude of the vibration V1, that is, V3 is V1 × 3;

in one embodiment, the contents of the third correspondence table are as follows:

ambient sound parameter	Vibration parameter
		D1	V1
D2	V2
		D3	V1

Table 3: third correspondence table

The corresponding vibration parameters can be obtained according to the environmental sound parameters and the third corresponding relation table, the central processing unit can send corresponding control signals to the flexible screen control chip, and the flexible screen control chip drives the flexible screen to vibrate correspondingly according to the control signals.

In example 1B, the effect of enhancing the volume can be achieved by the vibration of the flexible screen, so that the flexible screen can regularly vibrate according to the audio notes, the volume of the audio playing can be increased, and weaker elements in the audio file can be better represented; and through having increased vibrations amplitude rank setting, use different vibrations amplitude when different environment sounds, can realize increasing the volume by different multiples to realize adjusting audio playback effect, and then promote the audio frequency and listen to the effect. In addition, the representation effect of bass can be increased through a vibration mode, and a stereo effect can be formed through two sound production modes of a loudspeaker and screen vibration.

Example 1C

In example 1C, the terminal has a central processor, a memory, a flexible screen control chip, a flexible screen, a speaker.

Wherein the speaker is used for playing audio.

Referring to fig. 6, the audio playing method of example 1C includes the steps of:

s310, collecting audio data to be played;

s320, analyzing the audio data to be played to obtain corresponding audio parameters;

s330, adjusting the bending parameters of the flexible screen according to the audio parameters to adjust the audio playing effect.

Referring to fig. 7, in some embodiments, step S310 includes the following sub-steps:

s311, acquiring an audio playing trigger signal of audio playing software;

and S312, acquiring the audio data to be played by using a memory according to the audio playing trigger signal.

In step S311, a user operation may be obtained through an input device of the terminal, and an audio playing trigger signal of the audio playing software is obtained by analyzing the user operation; or the central processing unit of the terminal can directly read the audio playing state of the audio playing software to generate an audio playing trigger signal. The audio playing trigger signal may be explained before the audio playing software plays the audio, may be generated when the audio playing software starts playing the audio, or may be generated in the audio playing software playing the audio.

In step S312, according to the audio playing trigger signal, the audio file (audio data to be played) may be stored in the temporary storage, so that the central processing unit can subsequently read the audio file from the temporary storage, and quickly analyze the audio parameters of the audio file.

Step S320, analyzing the audio data to be played to obtain corresponding audio parameters.

In some embodiments, the audio parameters include a spectral distribution parameter and a vibration amplitude parameter, and referring to fig. 8, step S320 includes the sub-steps of:

s321, analyzing the audio data to be played to obtain a frequency spectrum of the audio data to be played;

s322, the obtained frequency spectrum distribution parameter and the obtained vibration amplitude parameter are judged according to the frequency spectrum of the audio data to be played.

In step S321, referring to the spectrograms of fig. 9a to 9c, in the spectrograms, the abscissa and the ordinate respectively represent the frequency and amplitude relationship of the audio data, i.e., the relationship of the signal frequency and the energy.

In step S322, the cpu can first quickly extract the audio data with high frequency of occurrence (more concentrated note occurrence) and large amplitude, and analyze the distribution area of the audio data in the spectrogram.

The distribution of the common audio in the spectrum is: 20-40Hz ultralow frequency; 40-80Hz low frequency; 80-160Hz medium and low frequency; 160-1280Hz intermediate frequency; high frequency in 1280 and 2560 Hz; 2560 and 5120Hz high frequency; 5120 and 20000Hz ultrahigh frequency.

In some embodiments, the frequency spectrum may be divided into three types S1, S2, S3 according to the frequency distribution region in which the frequency spectrum is located:

s1: ultra-low frequency-medium low frequency 20-160 Hz;

s2: middle and low frequency-middle and high frequency 160 and 2560 Hz;

s3: high frequency-ultrahigh frequency 2560-20 KHz;

where S is taken from the first letter of spectrum. The audio parameters include spectral distribution parameters and vibration amplitude parameters. By quickly extracting audio data with high occurrence frequency (more concentrated note occurrences) and large amplitude and analyzing the distribution area of the audio data in the spectrogram, the frequency spectrum distribution parameters and the vibration amplitude parameters of the audio to be played can be obtained. The analytical procedure was as follows:

referring to fig. 9a, if audio data with high frequency and large amplitude occurs, the spectral distribution parameter S is concentrated in a certain frequency band region of S1, S2, S3, or occurs in the spectral distribution region of S1+ S2, i.e. the spectral distribution parameter S is not greater than S1+ S2, and the average amplitude (amplitude parameter a) is not greater than 40dB (a <40dB), the audio is judged to be of music styles such as classical music, songgar, country, ballad, etc., and the music styles have fewer audio elements and have a relaxed tempo.

Referring to fig. 9b, if the frequency range of the audio parameter distribution in the spectrogram is wide, for example, the region of the spectral distribution parameter S in the spectrogram is S1+ S2+ S3; and the average amplitude (amplitude parameter A) is not more than 40dB (A <40dB), the music is judged to be popular music, ballad music and other music styles, and the music style has wider audio frequency and is relatively gentle.

Referring to fig. 9c, if the frequency range of the audio data displayed in the spectrogram is wide and the amplitude parameter a is large, for example, the spectral distribution parameter S is distributed as S1+ S2+ S3, and the average amplitude (amplitude parameter a) exceeds 40dB (a >40dB), it is determined that the music is a music style such as symphony, rock, jazz, or metal music, which is large in energy and has many audio elements.

In summary, by reading the distribution of the audio parameters with higher frequency and larger amplitude in the spectrogram of the audio file to be played, the existing music style is compared with the preset spectrum distribution mode in the memory, and in some embodiments, the correspondence between the audio parameters of different music styles and audio files is as follows:

table 4: music style and audio parameter corresponding table
