In the present embodiment, described microphone 30 is the rear microphone of mobile phone 100, for pick up during in talking state when described mobile phone 100 described mobile phone 100 background environment noise and be translated into the analog quantity of voltage, described analog to digital converter 40 gather from described microphone 30 described environmental noise voltage analog quantity and be translated into the digital quantity of voltage.In the present embodiment, described sound volume regulating system 10 is volumes that the voltage of the environmental noise that gathers according to described analog to digital converter 40 regulates described receiver 20.
In the present embodiment, described sound volume regulating system 10 can be divided into one or more modules, and described one or more module stores have been carried out function provided by the invention in described memory 50 and by described processor 60.For example consult shown in Fig. 2, described sound volume regulating system 10 is divided into module 11, read module 12, computing module 13, judge module 14 and adjusting module 15 is set.The alleged module of the present invention has been the program segment of a specific function, will in the flow chart of Fig. 3, specifically describe about the function of each module.
Consulting shown in Fig. 3, is the flow chart of the preferred embodiment of volume adjusting method of the present invention.
Step S1, arranges the default typical problem adjustment form of module 11, and described typical problem adjustment form defines the volume rank that different noise voltage value scopes are corresponding different.
For example consult Fig. 5 A, described arrange module 11 to the different volume ranks of described mobile phone 100 1～10 rank respectively corresponding noise voltage value scope divide, as can be seen from the figure, describedly module 11 is set the noise voltage value scope definition that double bass magnitude Ji 1 rank is set is U<=0.1V, it is U>0.9V that the noise voltage value scope definition that descant magnitude Ji 10 rank is set, and volume rank 2～9 rank respectively corresponding noise voltage value scope one-tenth etc. point arrange.
Step S2, microphone 30 is at mobile phone 100 during in talking state, pick up described mobile phone 100 background environment noise and be translated into the analog quantity of voltage.Analog to digital converter 40 gather from described microphone 30 described environmental noise voltage analog quantity and be translated into the digital quantity of voltage.Read module 12 reads the magnitude of voltage of the environmental noise that described analog to digital converter 40 gathers according to default reading frequency.
For example, described read module 12 reads once the magnitude of voltage of the environmental noise that described analog to digital converter 40 gathers according to the every 200ms of default reading frequency, for example, reading noise voltage value is respectively 0.1V, 0.2V, 0.1V, 0.16V, 0.14V, 0.2V, 0.2V, 0.2V, 0.2V, 0.2V, 0.2V, 0.3V ...
Step S3, computing module 13 is often reading the average voltage level of calculating this N environmental noise magnitude of voltage after N environmental noise magnitude of voltage, and using obtained average voltage level as a voltage reference value, described N can be 10.
For example, the average voltage level that described computing module 13 calculates read front 10 noise voltage values is 0.17V, using 0.17V as a voltage reference value.
Step S4, judge module 14 is often obtaining judging after M item voltage reference value that this M item voltage reference value is whether all within the defined a certain noise voltage value scope of described typical problem adjustment form continuously, described M can be 3, if, execution step S5, if not, process ends.
For example, in step S3 computing module 13 to calculate voltage reference value be respectively 0.17V, 0.16V, 0.18V, 0.2V, 0.26V, 0.45V ...In the time obtaining continuously 0.17V, 0.16V, this 3 voltage reference values of 0.18V, judge module 14 judges that these 3 voltage reference values that obtain are continuously whether all within the defined a certain noise voltage value scope of described typical problem adjustment form, for example interpretation show that these 3 voltage reference values all within 0.1 ~ 0.2V scope, now perform step S5.
And for example, in the time that 3 voltage reference values that next obtain continuously in judgement are 0.2V, 0.26V, 0.45V, because voltage reference value 0.2V, 0.26V are within the defined 0.2～0.3V scope of described typical problem adjustment form, and voltage reference value 0.45V is within 0.4～0.5V scope, these 3 voltage reference values that obtain are not continuously all between the defined same noise voltage value scope of described typical problem adjustment form, now process ends, does not adjust the volume of receiver 20.
Step S5, the volume of described receiver 20 is adjusted into the corresponding volume rank of described a certain noise voltage value scope by adjusting module 15.
For example, when at step S4, judge module 14 judges that 3 voltage reference value 0.17V, 0.16V obtaining continuously, 0.18V are within the defined 0.1 ~ 0.2V scope of described typical problem adjustment form, and the volume of described receiver 20 is adjusted into i.e. i.e. 2 rank of the corresponding volume rank of 0.1 ~ 0.2V of this noise voltage value scope by described adjusting module 15.The current volume of supposing described receiver 20 is i.e. 7 rank of default volume rank, and described adjusting module 15 is adjusted into 2 rank by the volume rank of described receiver 20 by 7 rank.
It should be noted that, when described adjusting module 15 is carrying out to described receiver 20 finding when volume is adjusted that the current volume rank of described receiver 20 equates with the volume rank after adjustment, described adjusting module 15 can not carried out volume adjustment action.
Consult Fig. 4 and show, after the volume of to be user manually adjusted during in talking state at mobile phone 100 receiver 20, reset the flow chart of typical problem adjustment form.
Step S11, judge module 14 judges whether user has manually adjusted volume in talking state process at mobile phone 100, if execution step S12, otherwise process ends.
For example, mobile phone 100 is in talking state process, and user is in the time that environmental noise magnitude of voltage is 0.6V, and volume is whole for 3 rank by 6 contrasts, now performs step S12.
Step S12, arranges module 11 and adjusts result according to user and reset typical problem adjustment form, and the typical problem adjustment form that this resets is repartitioned noise voltage value scope to different volume ranks.
