S23：According to the broadcast sound volume of current environment volume adjusting media player.Finally calculated according in step S22
The size of obtained current environment volume adjusts the broadcast sound volume of media player, in this way, realizing in good time according to current environment
Volume automatically adjusts broadcast sound volume so that the broadcast sound volume of media player adapts to the environment residing for user automatically, such as noisy
Under environment, broadcast sound volume can become big, and relatively under quiet environment, broadcast sound volume can diminish, and be operated without user, avoid existing
Have in technology because of the bad experience that regulation volume is brought to user manually, improve the hommization of broadcast sound volume regulation.
Alternatively, step S22 can include：Obtain volume corresponding to current environment audio and characterize intensity；According to volume indicator
Levy volume calculation formula corresponding to intensity selection；The current environment volume according to corresponding to volume formula calculates current environment audio.
Specifically, when calculating current environment volume, obtain current volume first and characterize intensity, herein volume characterize intensity can be by
User selectes in advance, and different volumes, which characterizes intensity, can correspond to different volume calculation formula, and volume indicator journey degree is being determined
Afterwards, you can the volume calculation formula chosen under the volume indicator journey degree calculates current environment volume corresponding to current environment audio,
In this way, volume calculation formula is different, fundamentally determine that same current environment audio has different volumes, actually should
With in environment, the audio in environment is usually uncertain, and volume distribution is uniform sometimes, and volume height has a long way to go sometimes, because

Selectivity, result of calculation is more showed the demand of user, improve Consumer's Experience.
As a kind of specific embodiment, when it is the first estate that the volume, which characterizes intensity, work as front ring according to described
The maximum and reference sound pressure of all audio sample points of border audio determine the volume calculation formula；Or when the volume characterizes
It is true according to the virtual value of all audio sample points of the current environment audio and the reference sound pressure when intensity is the second grade
The fixed volume calculation formula；Or when it is the tertiary gradient that the volume, which characterizes intensity, according to the institute of the current environment audio
There are the average value of audio sample point and reference amplitude to determine the volume calculation formula.Specifically, when volume characterizes intensity as the
During one grade, volume calculation formula can be：
Wherein, LPFor current environment volume, Prms1 is the maximum of all audio sample points of current environment audio,
Pref is reference sound pressure；Or when it is the second grade that volume, which characterizes intensity, volume calculation formula can be：
Wherein, LPFor current environment volume, Prms2 is the virtual value of all audio sample points of current environment audio,
Pref is reference sound pressure；Or when it is the tertiary gradient that volume, which characterizes intensity, volume calculation formula can be：
Wherein, LPFor current environment volume, A1For the average value of all audio sample points of current environment audio, A0It is ginseng
Examine amplitude.Specifically, if characterizing volume by audio amplitude, intensity is characterized for the volume of different stage, no
The scheme of same volume calculation formula is described as follows：
First level：In T second current environment audios, current environment sound is characterized by calculating the maximum of all sampled points
Amount；There are the following two kinds acquisition modes for the maximum of all sampled points：
Mode one：The current environment audio of T seconds is first first recorded using MediaRecorder or AudioSource, then
Using MediaRecorder or AudioSource method getMaxAmplitude (), all samplings in this T seconds are obtained
The maximum of point.
Mode two：The audio of T seconds is first recorded, preserves the pcm voice datas of this T seconds, each sampled point is taken out in then circulation
Compare, until calculating maximum.Then current environment volume is calculated using equation below：
Wherein, LPFor current environment volume, Prms1 is the maximum of all sampled points, and Pref is that reference sound pressure (is generally
20 micro- pas, the minimum acoustic pressure that the mankind can hear).The current environment volume come out by audio sample point maximum value calculation is to ring
The sign of border sound more block, strong, but can be influenceed by Outliers, such as, at a certain moment, there is leviathan to drop and generate
One sound loud noise, if the loud noise is collected, result of calculation will be made very big, and current environment is possible to overall relatively peace in fact
It is quiet.
Second level：In T second current environment audios, characterized by calculating the virtual value of all audio sample points current
Environmental volume, that is, the pcm voice datas of the T second current environment audios of recording are preserved, then therefrom each sampled point is taken out in circulation,
Their root-mean-square value is calculated using equation below：
Wherein, XiThe value of ith sample point is represented, N represents the sampling number in the T seconds, XrmsRepresent the equal of all sampled points
Root；Then current environment volume is calculated using equation below：
Wherein, LPFor current environment volume, Prms2 is the virtual value of all audio sample points, and Pref is reference sound pressure (one
As be 20 micro- pas, the minimum acoustic pressure that the mankind can hear).Work as front ring by what the virtual value of all audio sample points was calculated
Border volume is less than first level to the sign degree of current environment audio, i.e., finally causes the volume adjusting of media player to ring
The influence sensitivity of border volume is less than the situation of first level.
Third level：In T second current environment audios, current environment is characterized by the average value of all audio sample points
Volume, that is, the pcm voice datas of the T second current environment audios of recording are preserved, then therefrom each sampled point is taken out in circulation, first asks
Their quadratic sum, then with quadratic sum divided by the sampling number in the T seconds；Current environment sound is finally calculated using equation below
Amount：
Wherein, LPFor current environment volume, A1For the average value of all audio sample points, A0It is that reference amplitude (typically takes 20
Amplitude corresponding to micro- pa sound pressure level, can directly it be taken 1) when calculating here.Obtained by the mean value calculation of all audio sample points
It is more stable to current environment volume, it is not easily susceptible to the influence of extreme case, but compared to passing through audio sample point maximum
The mode of calculating, it is slower to the sign of environmental volume.
It should be noted that for different demands (degree of the DB to the sign of ambient sound), it can consider and carry above
To three kinds of algorithms of computing environment volume determine the grade classification of volume indicator journey degree, such as, the T seconds be divided into n deciles, taken
The maximum of each decile sound intermediate frequency sampled point, then again by all these maximums, according to being carried in default volume sensitivity 2
The algorithm arrived, their quadratic sum is first sought, then with quadratic sum divided by n, the volume DB values so calculated can be between above-mentioned first
Between current environment volume corresponding to rank and second level.Naturally, the mode of calculating current environment volume of the invention is simultaneously
Above-mentioned calculating combination is not limited to, as long as the calculation for being that by the technical scheme of the present embodiment is applied to
The present invention.
Alternatively, step S23 can include：Obtained and worked as according to the corresponding relation between environmental volume and media play volume
Broadcast sound volume grade corresponding to preceding environmental volume；The broadcast sound volume of media player is adjusted to matchmaker corresponding to broadcast sound volume grade
Body broadcast sound volume.Specifically, pair established between environmental volume and media play volume can be accustomed to previously according to human auditory
The form that should be related to, broadcast sound volume grade can be marked in relation table, after current environment volume is calculated, from relation table
Broadcast sound volume grade corresponding to current environment volume is obtained, then with media play volume adjusting corresponding to the broadcast sound volume grade
The form of corresponding relation between the broadcast sound volume of media player, such as environmental volume and media play volume may be referred to as
Under type is established：
The tier definition of broadcast sound volume is 0-15 ranks (0 by android system：Volume is minimum, equivalent to Jing Yin, 15：Sound
Sound is maximum) according to " decibel " entry on wikipedia, it is 15 grades that DB, which is divided, respectively the 1-15 of corresponding A ndroid systems
Prompt tone grade, the form of the corresponding relation between environmental volume and media play volume can be obtained, it is as shown in the table：
| DB | Prompt tone grade |
| 0-10 is extremely quiet, almost imperceptible | 1 |
| 10-20 | 2 |
| 20-30 is quiet, softly talks | 3 |
| 30-35 | 4 |
| 35-40 | 5 |
| 40-45 is general, and general room is talked | 6 |
| 45-50 | 7 |
| 50-55 | 8 |
| 55-60 | 9 |
| 60-65 is noisy | 10 |
| 65-70 | 11 |
| 70-80 is very noisy, and nerve cell can have an impact | 12 |
| 80-90 | 13 |
| 90-100 impaired hearings | 14 |
| More than 100 | 15 |
Certainly, the level of sound volume distribution shown in upper table, can be adjusted as the case may be and reasonably, for example mobile phone plays sound
Sound size, intensity of variation level and level between etc. of the amount grade per one-level can be all adjusted.Calculating current environment sound
During amount, you can corresponding volume-level (i.e. broadcast sound volume grade) is matched from upper table, then by the broadcasting of media player
Volume adjusting is to the volume-level, in this way, the volume that media play volume is not only selected with user characterizes intensity and current environment
Audio is relevant, also suffers from the influence of the volume use habit of user so that media play volume, which more meets the personal of user, to be needed
Ask, more hommization.
