Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment belongs to the scope of protection of the invention.
Referring to Fig. 1, the process that Fig. 1 is the first embodiment of the sound adjusting method of terminal device provided by the invention is shown It is intended to.The sound adjusting method of terminal device in the present embodiment includes:
S101: the sound that the terminal device is issued according to the first sound recipient received determines first sound Position where sound recipient.
It is understood that terminal device in the application according to the sound that the first sound recipient received issues come Determine that the execution of the event of the position where the first sound recipient can be by terminal device system automatic trigger, such as in terminal The trigger condition for executing above-mentioned event is preset in device systems.The condition can be first whithin a period of time in terminal device Secondary when receiving sound, terminal device can determine that the first sound connects according to the sound of the first sound recipient sending received Position where debit, such as user is in using terminal device plays some videos, certain song or incoming call answering, eventually End equipment only needs to receive the sound that user issues for the first time, to determine the position of user；The condition is also possible in terminal device Real-time reception determines the first sound recipient to sound, and according to the sound that the first sound recipient received issues come real-time The position at place, such as user, in using terminal device plays some videos, certain song or incoming call answering, terminal is set It is standby only to need to receive the sound that user issues for the first time, to determine the position of user.
S102: according to the position where the first sound recipient, the volume of the loudspeaker of the terminal device is adjusted Parameter makes the sound of the loudspeaker sending when reaching the position where the first sound recipient and the first default volume Between volume difference be lower than the first preset threshold.
Loudspeaker is a kind of electro-acoustic element for converting electrical energy into sound energy, and there are many type of loudspeaker, although their work Make mode difference, but be all finally the air for pushing surrounding by generating mechanical oscillation, air dielectric is made to generate fluctuation to real The conversion of existing " electricity-power-sound ".Therefore the sound that loudspeaker issues is mechanical wave, and mechanical wave propagation requires medium, general next It says, speaking in our daily lifes is by airborne, and there are also such as sonars, are used in navigation, then sound is to pass in water It broadcasts, there are also solids can also be transaudient, such as steel, bone etc..Since sound is propagated by vibration medium, medium shakes meeting There is kinetic energy, the energy attenuation of sound in the air is mainly exactly the kinetic energy for being converted into medium；For sound wave in communication process, As long as medium is constant, velocity of wave, wavelength, frequency be all it is constant, only amplitude is constantly reducing；Such as loudspeaker is at A It makes a sound, needs user that can hear at B, then the loudness for the sound that loudspeaker issues at A just has to make During sound transmission after off-energy, the amplitude of sound or loudness can also cause the sense of hearing of the user at B when at B.
Therefore, it behind position where terminal device has determined the first sound recipient, can be received according to the first sound Position where side, adjusts the volume parameters of the loudspeaker of terminal device, and the sound for issuing loudspeaker is through overdamping and arrives The volume difference between wave volume and the first default volume when up to position where the first sound recipient is default lower than first Threshold value.It is understood that the first default volume can be by user's self-setting；For example, user is accustomed to 50db's or 60db Volume, therefore the first default volume can be arranged to 50db or 60db, so that the sound warp that the loudspeaker of terminal device issues Overdamping and wave volume when reaching the position where user are 50db or 60db.In practical applications, sound declines Subtract it is sufficiently complex, for example, sound is propagated in air, viscosity, the temperature of air, humidity and the air pressure etc. of decaying and air There is relationship, therefore when the volume parameters for the loudspeaker for adjusting terminal device, the sound for issuing loudspeaker reaches the first sound When wave volume when position where sound recipient is the first default volume, it is poor often to there is certain volume, and general , when the range of volume difference is lower than the first preset threshold, the first sound recipient can satisfy it and raise to what is received The volume requirement for the sound that sound device issues.Certainly, which can be designed for different users, such as 5db or 10db, i.e. terminal device adjust the volume of the loudspeaker of terminal device according to the position where the first sound recipient Parameter, volume of the sound for issuing loudspeaker when reaching the position where the first sound recipient between the first default volume Difference is lower than 5db or 10db.
In a specific implement scene, some video of using terminal device plays, user are opposite in the room by user After terminal device says " adjusting volume ", terminal device determines the position where user according to user's one's voice in speech, such as The distance between user and terminal device and direction etc.；Then terminal device adjusts terminal and sets according to the position where user The volume parameters of standby loudspeaker make loudspeaker play the sound of sound that the video is issued when reaching the position where user Amount is 50db；Then, in the influence for fully taking into account user and terminal device local environment, the loudspeaker that end user hears is broadcast The sound size for putting the video is 49db, since using terminal equipment, the sound of 50db or so not will lead to user in the room User does not hear the sound-content of video playing, will not cause to bring bad usage experience to user too loudly.
In the present embodiment, terminal device determines the by the sound issued according to the first sound recipient for receiving Position where one sound recipient, and according to the position where the first sound recipient, adjust the loudspeaker of terminal device Volume parameters, the sound for issuing loudspeaker is when reaching the position where the first sound recipient between the first default volume Volume difference is lower than the first preset threshold, so as to adjust the sound of loudspeaker according to the distance between user and terminal device Size prevents the distance between user and terminal device too far and user is caused to can't hear sound or user and terminal device The distance between it is too close and user is caused to hear too loudly.

△ P=P2-P1=20lg (L2/L3) (1)；
As with the speed V of third distance L3 being by second distance L2 due to sound again, then second distance L2 and There are relationships by time difference △ T between third distance L3 and the first acquisition time T1 and the second acquisition time T2:
△ T=T2-T1=(L3-L2)/V (2)；
Then, according to relationship (1) and relationship (2), can in the hope of second distance L2, third distance L3 respectively with volume difference △ P, there are following relationships between time difference △ T and the spread speed V of sound:
L2=V* △ T/ (10△P/20-1)；
L3=V* △ T/ (10△P/20-1)+V*(△T)。
Therefore, terminal device according to the first of acquisition acquisition volume P1 and second acquisition volume P2 between volume difference △ P, The spread speed V of time difference △ T and sound between first acquisition time T1 and the second acquisition time T2, can determine first The third between second distance L2 and the first sound recipient and second microphone between sound recipient and the first microphone Distance L3.
