Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
Fig. 1 is the method flow schematic diagram of automatic regulating volume of the present invention, as shown in Figure 1, comprises the following steps:
Step 101: the voice data that equipment of putting outside collection present terminal sends, obtains the loudness value of current sound;
Here, before the voice data that equipment of putting outside described collection present terminal sends, the method also comprises: the function of opening automatic regulating volume;
Concrete, technical solution of the present invention has the function of opening or closing automatic regulating volume, the impact being subject to external sound due to voice data is larger, when external sound is larger, when the collection of the voice data that equipment sends externally is put in impact, impact can be brought on automatic regulating volume, therefore, can be opened or close the function of automatic regulating volume by user according to the actual environment in the external world.
Here, described voice data comprises the sound intensity put equipment outside present terminal and send.
Step 102: the loudness value of the current sound of acquisition and the sound intensity value preset are compared, according to comparative result, current volume value is adjusted;
Here, suppose that the loudness value of current sound is Vt, default sound intensity value is Vs; Concrete, with reference to shown in Fig. 2, step 102 comprises:
Step 102a: judge the sound intensity value Vs whether the loudness value Vt of current sound equals default, if the result judged is yes, then performs step 102b, terminates current treatment progress; Otherwise, perform step 102c;
Here, described default sound intensity value Vs is arranged according to self needing voluntarily for user, for user feels optimum sound intensity.
Step 102c ~ 102e: compare the loudness value Vt of current sound and default sound intensity value Vs, if Vt is greater than Vs, then turn the volume value of present terminal down, perform step 102a, until Vt equals Vs, terminate current treatment progress; If Vt is less than Vs, then tune up the volume value of present terminal, perform step 102a, until Vt equals Vs, terminate current treatment progress;
Here, comparison module sends a signal to sound adjusting module and informs to sound adjusting module by the comparative result of Vt and Vs; Sound adjusting module adjusts acoustic gain parameter according to the signal received; Wherein, described acoustic gain parameter can affect the actual play loudness of sound.
Here, when loudness value and the sound intensity value preset of current sound are inconsistent, can regulate step by step by the least unit of present terminal volume value, until the loudness value of current sound is consistent with the sound intensity value preset;
Or loudness value and the default sound intensity value of current sound have big difference, and can carry out adjustment volume, be equivalent to arrange a volume adjusting amplitude by N number of least unit of present terminal volume value, can accelerate to regulate sound intensity.
Such as, the volume value of terminal is between 0 to 100, and least unit is 1, if the loudness value of current sound is 70 decibels, and the sound intensity value preset is 60 decibels, then need the volume value turning present terminal down, make the loudness value of current sound be reduced to 60 decibels; If the current volume value of terminal is 30, then can regulate step by step by the least unit of volume value, the volume value of terminal is adjusted to 29, the voice data that equipment sends is put outside continuation collection present terminal, the loudness value of the current sound of acquisition is compared with the sound intensity value preset, till the loudness value of current sound is equal with the sound intensity value preset;
Such as, the loudness value of current sound is 75 decibels, and the sound intensity value preset is 45 decibels, differs 30 decibels, needs the volume value turning present terminal down, make the loudness value of current sound be reduced to 45 decibels; The volume value of terminal is between 0 to 100, least unit is 1, suppose that current volume value is 35, can regulate by the least unit of 5 volume values, volume value is adjusted to 30, put the voice data that equipment sends outside continuation collection present terminal, the loudness value of the current sound of acquisition is compared with the sound intensity value preset, till the loudness value of current sound is equal with the sound intensity value preset.
Here, specifically regulate volume still can be selected by the comparative result of comparison module according to the loudness value of current sound and default sound intensity value by volume adjusting amplitude adjusted volume by least unit, and send to sound adjusting module by signal.
Fig. 3 is the device composition structural representation of automatic regulating volume of the present invention, and as shown in Figure 2, this device comprises sound monitoring module 32, comparison module 33 and sound adjusting module 35; Wherein,
Described sound monitoring module 32, for gathering voice data, obtaining the loudness value of current sound, the loudness value of acquisition is sent to comparison module 33;
Described comparison module 33, the loudness value for current sound sound monitoring module 32 sent compares with the sound intensity value preset, and comparative result is sent to sound adjusting module 35;
Described sound adjusting module 35, adjusts current volume value for the comparative result sent according to comparison module 33.
Further, this device also comprises memory module 34, for storing default sound intensity value.
Further, described sound adjusting module 35, specifically at comparative result be the loudness value of current sound be greater than default sound intensity value time, turn current volume value down, until the loudness value of current sound equals default sound intensity value; When the loudness value that comparative result is current sound is less than default sound intensity value, tune up current volume value, until the loudness value of current sound equals default sound intensity value.
Further, this device also comprises outer puts equipment 31, for according to actual volume value output audio signal.
Further, this device also comprises switch module, for opening or close the function of automatic regulating volume.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.All any amendments done within the spirit and scope of the present invention, equivalent replacement and improvement etc., be all included within protection scope of the present invention.
