Specifically, it is determined that the process that this bending stress parameter is direct stress parameter or negative stress parameter may include that
Determine the case of bending of this flexible display unit, wherein, this stress mornitoring unit is arranged on front or the back side of this flexible display unit, the case of bending of this flexible display unit includes positive curve state and hogging bending state, this positive curve state refer to this flexible display unit on this terminal unit thickness direction to away from the state during curving of this stress mornitoring unit, this hogging bending state refer to this flexible display unit on this terminal unit thickness direction to state during near the curving of this stress mornitoring unit；If this flexible display unit is in positive curve state, it is direct stress parameter determining this bending stress parameter that this stress mornitoring unit detects；If this flexible display unit is in hogging bending state, it is determined that this bending stress parameter that this stress mornitoring unit detects is negative stress parameter.
Wherein, when this flexible display unit on this terminal unit thickness direction to during away from the curving of this stress mornitoring unit, that is to say when being in positive curve state, this stress mornitoring unit will be by tension, and now this stress mornitoring unit i.e. can detect that the direct stress parameter corresponding with this tension size；Correspondingly, when this flexible display unit on this terminal unit thickness direction to during near the curving of this stress mornitoring unit, that is to say when being in hogging bending state, this stress mornitoring unit will be by compressive stress, and now this stress mornitoring unit i.e. can detect that the negative stress parameter corresponding with this compressive stress size.
Such as, with reference to Fig. 2 B, if this stress mornitoring unit is arranged on the back side of this flexible display unit, two ends when user's hand-held terminal device, when the two ends of this terminal unit are converted into the front of this terminal unit, with reference to Fig. 2 C, this Flexible Displays display unit will be in positive curve state, this stress mornitoring unit i.e. can detect that direct stress parameter, thus this terminal unit can the increase of media volume based on this direct stress this terminal unit of parameter determination, and the media volume of this terminal unit is increased；And when the two ends of user's hand-held terminal device, when the two ends of this terminal unit are converted into the back side of this terminal unit, with reference to Fig. 2 D, this Flexible Displays display unit will be in hogging bending state, this stress mornitoring unit i.e. can detect that negative stress parameter, thus this terminal unit can determine the reduction amount of media volume of this terminal unit based on this negative stress, and the media volume of this terminal unit is reduced.
Correspondingly, if this stress mornitoring unit is arranged on the front of this flexible display unit, two ends when user's hand-held terminal device, when the two ends of this terminal unit are converted into the front of this terminal unit, this Flexible Displays display unit will be in hogging bending state, this stress mornitoring unit i.e. can detect that negative stress parameter, thus this terminal unit can the reduction amount of media volume based on this negative stress this terminal unit of parameter determination, and the media volume of this terminal unit is reduced；And when the two ends of user's hand-held terminal device, when the two ends of this terminal unit are converted into the back side of this terminal unit, this Flexible Displays display unit will be in positive curve state, this stress mornitoring unit i.e. can detect that direct stress parameter, thus this terminal unit can determine the increase of media volume of this terminal unit based on this direct stress, and the media volume of this terminal unit is increased.
In the embodiment of the present invention, based on this direct stress parameter, determine the increase of the media volume of this terminal unit, and based on this negative stress parameter, determine the media volume of this terminal unit reduction amount realize process, can include any one in the following manner:

Example, corresponding relation between the direct stress parameter prestored and media volume increase, negative stress parameter and media volume down a small amount of, as shown in following table table one, certainly being merely illustrative of, the corresponding relation not represented between the bending stress parameter of the embodiment of the present invention and media volume adjustment amount is confined to this herein.
Table one
| Bending stress is positive and negative | Bending stress (P) size | Media volume adjustment amount |
| Direct stress | P>1pa | Increase 20 decibels |
| Direct stress | 0.1pa<P≤1pa | Increase 10 decibels |
| Negative stress | P>1pa | Reduce 20 decibels |
| Negative stress | 0.1pa<P≤1pa | Reduce 10 decibels |
In the second way, this terminal unit can calculate the media volume adjustment amount of this terminal unit based on this bending stress parameter according to formula, and this media volume adjustment amount includes media volume increase and media volume down in a small amount.
Such as, this terminal unit can use below equation calculate media volume adjustment amount:
δ=P/a；
Wherein, δ is media volume adjustment amounts, and P is the bending stress parameter of this flexible display unit, and a is the conversion coefficient of bending stress parameter and media volume adjustment amount.
Wherein, this conversion coefficient a can be constant, such as 0.5,1,2 etc., can also be constant b and this terminal equipment configuration media volume standard volume between quotient, such as, if the standard volume of the media volume of this terminal equipment configuration is x, then this conversion coefficient can be b/x, in actual application, standard volume x of media volume is usually 80 decibels etc., and this is not limited by the embodiment of the present invention, and constant b can be by terminal unit default setting, can also be by user setup, this is not limited by the embodiment of the present invention.
Such as, if this conversion coefficient a is 0.5, then, when the size of the stress parameters P obtained is 1Pa, the adjustment amount of this media volume is 2 decibels；If this conversion coefficient a is b/x, x is 80 decibels, b is 10, then, when the stress parameters P obtained is 1Pa, the adjustment amount δ of this media volume is 0.1x, that is to say 8 decibels.
Wherein, this bending stress parameter P can be direct stress parameter, it can also be negative stress parameter, when this bending stress parameter P is direct stress parameter, the adjustment amount δ of this media volume is media volume increases, when this bending stress parameter P is negative stress parameter, the adjustment amount δ of this media volume is media volume down a small amount of.
Such as, as a example by above-mentioned formula, if conversion coefficient a is 0.2, when this bending stress parameter P is direct stress parameter, and stress intensity is when being 1Pa, this bending stress parameter P can be expressed as 1Pa, then can calculate the adjustment amount δ of this media volume by above-mentioned formula is 2 decibels, that is to say that media volume increase is 2 decibels；When this bending stress parameter P is negative stress parameter, and stress intensity is when being 1Pa, this bending stress parameter P can be expressed as-1Pa, then can calculate the adjustment amount δ of media volume by above-mentioned formula and be-2 decibels, that is to say that media volume down is 2 decibels in a small amount.
By above two mode, this terminal unit can realize the Serial regulation of bending stress parameter correspondence media volume.
In the embodiment of the present invention, the increase of media volume based on this terminal unit or reduction amount, adjust the media volume to terminal unit, that is to say, the media volume of this terminal unit is increased this media volume increase and maybe the media volume of this terminal unit is reduced this media volume down in a small amount.
The method provided by the embodiment of the present invention, can realize when flexible display unit is curved inwardly by user, current media volume is increased, when flexible display unit is bent outwardly by user, current media volume is reduced, or when flexible display unit is curved inwardly by user, current media volume is reduced, when flexible display unit is bent outwardly by user, current media volume is increased, thus improve the motility that media volume adjusts, user operation is more convenient.
