As shown in Figure 1, the changing method of a kind of mobile terminal call pattern that the present embodiment provides, specifically comprises the steps:
Step S101, detect described pressure touch and shield the pressing force born, determine the force value of described pressing force.
In the present embodiment, described pressure touch screen can be understood as the touch screen that has pressure transducer functionality, can be used for induction mobile terminal and whether bears pressing force.Described pressure touch screen can sense the pressing dynamics suffered by screen compared with the existing touch screen of mobile terminal.Further, when detecting that touch screen has born pressing force, just can determine the force value of suffered pressing force.
In the present embodiment, user can produce pressure by any point of finger presses touch screen, user also can apply pressure by other positions of health such as cheek or ear to touch screen, makes pressure touch shield thus and can sense the pressing force of user to mobile terminal.
Step S102, judge the pressure threshold whether described force value reaches default.
In the present embodiment, when detecting that the pressure touch screen of mobile terminal has born pressing force, and after determining force value, need to judge whether the force value of bearing reaches default pressure threshold.Determine whether the condition reaching call mode switching thus.
In the present embodiment, when user converses under noisy environment, if surrounding environment influence speech quality, by applying to the touch screen of mobile terminal the automatic switchover that pressing force carries out call mode.Concrete, user can when mobile terminal leave ear, by any point of finger presses touch screen or directly press touch screen based on ear or cheek, then determines the force value of pressing force; Judge whether force value reaches preset pressure threshold value afterwards in step s 102.
Further, the preset range of described pressure threshold is 0.1N ~ 0.5N.
In the present embodiment, described pressure threshold is specially and judges whether mobile terminal reaches the pressure threshold of call mode switching condition.Usually, the value of described pressure threshold (pressure threshold) is not an occurrence, but a value range, and must set this value range can not be too low or too high, the too low meeting of range set causes the sensitivity of mode switch function too high, reduces Consumer's Experience; Span is too high pattern can be caused again to switch in too low to the sensing capability of pressure, the functional characteristic that same Effect Mode switches.Preferably, the setting of pressure threshold is limited between 0.1N ~ 0.5N by the embodiment of the present invention.
If the described force value of step S103 reaches pressure threshold, then switching present talk mode is large volume handset mode.
In the present embodiment, after in step S102 to the judgement of force value, if force value reaches default pressure threshold, then just start call mode handoff functionality, call mode is made to switch to large volume handset mode by current state, thus when dialog context is not heard by stranger, ensure the speech quality of user.Described large volume handset mode can be understood as: compared with reaching the highest situation with normal handset mode volume, still In Call can be improved certain decibel again, and compared with existing loud speaker (putting) call mode, can ensure that again dialog context is not heard by stranger outward.
The changing method of a kind of mobile terminal call pattern that the present embodiment one proposes.In communication process, the pressure touch detecting mobile terminal shields the pressing force born, and determines the force value size of pressing force; Then judge whether force value reaches default pressure threshold, if reach pressure threshold, then switching present talk mode is large volume call mode.Utilize the method, when conversing under achieving noisy environment, normal handset mode is to the conversion of large volume handset mode, solve when prior art carries out call mode conversion and take time and effort and the problem of pattern performance of handoffs instability, the object simple under reaching noisy environment, quick, high stability carries out call mode switching, ensure that call definition and the speech quality of mobile terminal under handset mode in noisy environment.

Further, also step " switching present talk mode is large volume handset mode " is specifically optimized for: adjust the Whole frequency band gain under normal handset mode, In Call is increased; And/or segmentation adjust normal handset mode under to converse the band gain of frequency response curve, high-band gain value is increased, and low-band gain value reduces.
As shown in Figure 2, the changing method of a kind of mobile terminal call pattern that the embodiment of the present invention two provides, specifically comprises following operation:
Step S201, when mobile terminal is in talking state, when detect described pressure touch screen born pressing force time, determine that described screen bears the force value of pressing force.
In the present embodiment, shielding to pressure touch the trigger timing that the pressing force that bears detects can when mobile terminal be in talking state.Described talking state comprises the incoming call of mobile terminal or the dial-out of user, and in addition, described talking state also comprises carries out situation about conversing by chat/talk application software.
In the present embodiment, described mobile terminal is a touch-control mobile phone or the touch-screen tablet computer with call function.Concrete, be also equipped with pressure touch function in the touch screen of described mobile terminal, mobile terminal screen can be experienced based on pressure touch function and whether bear pressure, and respond different operations based on the difference of born pressure.Exemplary, as in the present invention by detected pressures touch screen the force value of bearing judge whether to reach the switching condition of mobile terminal call pattern.
Step S202, judge the pressure threshold whether described force value reaches default, if so, then perform step S203; If not, then step S204 is performed.
In the present embodiment, when detecting that through step S201 mobile terminal has born pressing force and after determining force value, judged whether force value reaches default pressure threshold scope 0.1N ~ 0.5N, if reach pressure threshold, then can perform step S203; If no, then perform step S204.
Step S203, switching present talk mode are large volume handset mode.
In the present embodiment, after the force value determined in step S201 reaches the scope 0.1N ~ 0.5N of pressure threshold, current call mode can be switched, this is switched to large volume handset mode.
Further, switching present talk mode is large volume handset mode, specifically comprises:
Adjust the Whole frequency band gain under normal handset mode, In Call is increased; And/or segmentation adjust normal handset mode under to converse the band gain of frequency response curve, high-band gain value is increased, and low-band gain value reduces.
In the present embodiment, switched to by present talk mode the mode of large volume pattern to have multiple, a kind of is the Whole frequency band gain under the normal handset mode of adjustment, increases In Call; A kind of for segmentation adjust normal handset mode under the frequency response curve conversed; One is also had to be not only adjusted Whole frequency band gain but also segmentation adjusts each band gain.It should be noted that, when described normal handset mode specifically can refer to converse, its session parameter arranged meets the handset mode of national transmission standard rule.Usually, the setting of session parameter comprises the call setting of frequency response curve and the setting of band signal, and the scope that arranges of described frequency response curve can not exceed the scope of the frequency response frame limited in national transmission standard; The scope that arranges of described band signal can not make the maximum of volume exceed the volume range limited in national transmission standard.
Concrete, for the mode of the Whole frequency band gain under the normal handset mode of adjustment, described Whole frequency band gain can be understood as in communication process, the signal strength signal intensity of whole frequency band in call is increased all accordingly, improve signal gain value, increase the signal strength signal intensity in communication process, make the In Call heard be increased thus, preferably, in call, the increase scope of the yield value of whole band signal is 3dB ~ 5dB; To converse under normal handset mode is adjusted for segmentation the band gain of frequency response curve, be specially the yield value adjusting high band and low-frequency range respectively, the yield value of high band is increased, the yield value of low-frequency range decreases, to change frequency response curve setting range, improve call definition thus, wherein, when segmentation adjusts the band gain of frequency response curve of conversing under normal handset mode, the preferable range that the yield value of high band increases is 3dB ~ 5dB, and the preferable range of the corresponding reduction of the yield value of low-frequency range is also 3dB ~ 5dB; The third is adjusted to the Mixed adjustment of mode based on first two, the adjustment of Whole frequency band can be realized, increase volume with this, the adjustment of each band frequency value can be realized again, increase the definition of call with this.
It should be noted that, when user converses under noisy environment, both call sides can increase the volume of speaking consciously, when volume improves, call signal strength signal intensity may reach-9dB and more than, run into this situation, when user carries out call mode switching based on the inventive method again, also there is the method for adjustment that another kind of normal handset mode becomes large volume handset mode.This method of adjustment can be summarized as: keep signal strength signal intensity in communication process be in-9dB and on band signal constant, only to adjust in communication process signal strength signal intensity lower than the band signal of-9dB, make it increase band gain, so under keeping large volume handset mode all band signal intensity all remain on-9dB and more than.This method of adjustment improve only the yield value of small-signal, also assures that the definition of call while increasing volume.
Usually, described frequency response curve is mainly divided into high frequency, intermediate frequency and low frequency three frequency ranges.Based on the arrowband standard that country formulates, the frequency values setting range of frequency response curve is: 300HZ ~ 3.4kHZ, and wherein, the frequency range of low-frequency range is 300HZ ~ 600HZ, the frequency range of Mid Frequency is 600HZ ~ 1.2kHZ, and the frequency range of high frequency band is 1.2kHZ ~ 3.4kHZ; Further, also set wide-bandwidth standards in country's call rule, the frequency values setting range that this medium standard frequency rings curve is: 100HZ ~ 8kHZ.At present, great majority call arranges and still adopts arrowband standard, and wide-bandwidth standards is also in developing gradually.The changing method that the present invention carries, all applicable to two kinds of frequency band standards.
Step S204, maintenance present talk mode are constant.
In the present embodiment, when force value does not reach pressure threshold, can regard that maintenance present talk mode is constant as.It should be noted that, when force value reaches pressure threshold, after call mode switches to large volume call mode, the screen continued to mobile terminal is no longer needed to apply pressure, under still remaining on large volume call mode, if think again to switch to normal handset mode, again pressure can be applied to mobile terminal, when determined force value reaches the pressure threshold of pattern switching again, just can realize the automatic switchover of call mode, again become normal handset mode.
Further, after described mobile terminal enters talking state, switch before present talk mode is large volume handset mode, adopt normal handset mode to converse.
In the present embodiment, after the talkthrough of mobile terminal enters talking state, mobile terminal can be given tacit consent to and enters normal handset mode until the switching condition that mobile terminal reaches call mode just enters large volume call mode.Therefore the present talk mode in the present invention first call mode is defaulted as normal handset mode before switching, and is also likely large volume call mode in operation afterwards.
Further, switch large volume handset mode and specifically comprise to normal handset mode: reduce the Whole frequency band gain under large volume handset mode, reduce volume; And/or segmentation adjusts the frequency response curve under large volume handset mode, lower high-band frequency value, promote low-frequency range frequency values.
The changing method of a kind of mobile terminal call pattern that the embodiment of the present invention two provides, when mobile terminal is in talking state, when detecting that described pressure touch screen has born pressing force, determine that described screen bears the force value of pressing force, if force value reaches default pressure threshold, then by the Whole frequency band gain under the normal handset mode of adjustment, increase In Call and enter large volume call mode; Or segmentation adjust normal handset mode under converse the band gain of frequency response curve to enter large volume call mode.Utilize the method, based on the pressure sensitive of 3D touch screen, when conversing under achieving noisy environment, normal handset mode is to the conversion of large volume handset mode, solve when prior art carries out call mode conversion and take time and effort and the problem of pattern performance of handoffs instability, the object simple under reaching noisy environment, quick, high stability carries out call mode switching, ensure that call definition and the speech quality of mobile terminal under handset mode in noisy environment.
