Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Fig. 1 is the method flow synoptic diagram of automatic regulating volume of the present invention, as shown in Figure 1, may further comprise the steps:
Step 101: gather current terminal and put the voice data that equipment sends outward, obtain the loudness value of current sound;
Here, the current terminal of described collection is put outward before the voice data that equipment sends, and 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, because it is larger that voice data is subject to the impact of external sound, when external sound larger, when the collection of the voice data that equipment sends is externally put in impact, can bring impact to automatic regulating volume, therefore, can open or close according to the actual environment in the external world function of automatic regulating volume by the user.
Here, described voice data comprises that current terminal puts the sound intensity that equipment sends outward.
Step 102: the loudness value of the current sound that will obtain compares with the sound intensity value of presetting, and according to comparative result current volume value is adjusted;
Here, the loudness value of supposing current sound is Vt, and default sound intensity value is Vs; Concrete, with reference to shown in Figure 2, step 102 comprises:
Here, described default sound intensity value Vs arranges according to self needs voluntarily for the user, for the user feels optimum sound intensity.
Here, comparison module sends a signal to the sound adjusting module comparative result of Vt and Vs is informed to the sound adjusting module; The sound adjusting module is adjusted the sound gain parameter according to the signal of receiving; Wherein, described sound gain parameter can affect the actual play loudness of sound.
Here, when loudness value and the default sound intensity value of current sound are inconsistent, can regulate step by step by the least unit of current terminal volume value, until the loudness value of current sound is consistent with default sound intensity value;
Perhaps, the loudness value of current sound and default sound intensity value have big difference, and can regulate volume by N least unit of current terminal volume value, are equivalent to arrange a volume adjusting amplitude, in order to can accelerate to regulate sound intensity.
For example, 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 default sound intensity value is 60 decibels, then needs to turn down the volume value of current terminal, makes 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, continue to gather current terminal and put the voice data that equipment sends outward, with the loudness value of the current sound that obtains and default sound intensity value relatively, until the loudness value of current sound with till the sound intensity value of presetting equates;
For example, the loudness value of current sound is 75 decibels, and default sound intensity value is 45 decibels, differs 30 decibels, need to turn the volume value of current terminal down, makes 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, continue to gather current terminal and put the voice data that equipment sends outward, with the loudness value of the current sound that obtains and default sound intensity value relatively, until the loudness value of current sound is with till the sound intensity value of presetting equates.
Here, specifically regulate volume by least unit and still can be selected with the comparative result of the sound intensity value of presetting according to the loudness value of current sound by comparison module by volume adjusting amplitude adjusted volume, and send to the sound adjusting module by signal.
Fig. 3 is the installation 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 harmony sound adjusting modules 35; Wherein,
Described sound monitoring module 32 is used for gathering voice data, obtains the loudness value of current sound, and the loudness value that obtains is sent to comparison module 33;
Described comparison module 33 compares for the loudness value of the current sound that sound monitoring module 32 is sent and default sound intensity value, and comparative result is sent to sound adjusting module 35;
Described sound adjusting module 35 is used for according to the comparative result that comparison module 33 is sent current volume value being adjusted.
Further, this device also comprises memory module 34, is used for the default sound intensity value of storage.
Further, described sound adjusting module 35 concrete is used for to be the loudness value of current sound during greater than default sound intensity value, to turn current volume value down, until the sound intensity value that the loudness value of current sound equals to preset at comparative result; Be the loudness value of current sound during less than default sound intensity value at comparative result, tune up current volume value, until the sound intensity value that the loudness value of current sound equals to preset.
Further, this device also comprises the outer equipment 31 of putting, and is used for according to actual volume value output audio signal.
Further, this device also comprises switch module, is used for opening or closing the function of automatic regulating volume.
