Specific implementation mode
To make the above purposes, features and advantages of the invention more obvious and understandable, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
Fig. 1 is the dimensional structure diagram of the intelligent sound box in one embodiment of the invention.Shown in referring to Fig.1, the intelligent sound
In case 1, several microphones 11 are distributed with around barrel, for receiving the sound wave that sound source is sent out, sound source is located at several microphones 11
Outside intelligent sound box 1, the information of received sound wave is used to judge the orientation of sound source.
Shown in referring to Fig.1, multiple microphones 11 can be fixed on cover, and it is inside and outside or be embedded in can also to be fixed on barrel
In barrel.Microphone 11 is a pressure sensor that can perceive acoustic pressure, and effect is sensed to improve, and is preferably exposed to extraneous sky
In gas.
Sound source can be user, or independently of the sound-producing device of intelligent sound box 1, it is therein refer to independently sounding not
It is controlled by intelligent sound box 1.
It is example user with sound source, Fig. 2 is the schematic diagram of the reception user's sound wave of intelligent sound box 1 in Fig. 1.With reference to Fig. 2 institutes
Show, it can be seen that multiple microphones 11 judge that the principle in the orientation of sound source is according to the information of the sound wave received：Multiple wheats
Gram wind 11 is far and near different apart from sound source.Under above-mentioned principle, on barrel, multiple microphones 11 can be located at sustained height.By
In 1 certain application scenarios of intelligent sound box, user location is changeable, to prevent two microphones 11 apart from the far and near equalization of user, position
It is at least three in the number of the microphone of sustained height.It is multiple to improve compatibility of the intelligent sound box 1 to various use occasions
Microphone 11 encloses equal distribution in barrel one.Microphone 11 shown in Fig. 1 and Fig. 2 is eight Mikes that equal distribution is enclosed around barrel one
Wind 11, in the specific use process, the not limited to of microphone 11 is in above-mentioned eight, or other numbers.
On the basis of above-mentioned intelligent sound box 1, the present invention also provides sound localization methods.Fig. 3 is the intelligent sound box in Fig. 1
Sound localization method flow chart.
Each step is discussed in detail individually below.
With reference to shown in Fig. 3, step S1 is first carried out, sound source sends sound wave towards intelligent sound box 1.
It should be noted that sound source in the present invention is the sound source independently of intelligent sound box 1, that is, be located at intelligent sound box 1 it
Outside, it is not controlled by intelligent sound box 1.
The sound source for meeting above-mentioned condition can be that equipment is pronounced, or user pronunciation.Such as equipment is to intelligent sound box 1
Instruction is sent, or is sent and is instructed by user.In addition to instruction, or non-mandatory voice, such as music etc..
Then step S2, the information of acoustic wave received according to several microphones 11 being distributed around intelligent sound box barrel are executed
Judge the orientation of sound source.
In one scheme, the information of acoustic wave received includes the time of reception.Fig. 4 is intelligent sound box in Fig. 1 according to Mike
The sequencing that wind receives carries out the schematic diagram of auditory localization.Specifically, with reference to shown in Fig. 4, in eight microphones 11：Distance
The nearest microphone 11 of sound source is initially received sound wave；Microphone 11 apart from next, second receives sound wave；Distance is thirdly
Microphone 11, third receives sound wave；The remote microphone 11 of inverse distance second, the 4th receives sound wave；Distance is farthest
Microphone 11, finally receives sound wave.As can be seen that the close microphone 11 for being initially received sound wave in orientation residing for sound source,
Far from the microphone 11 for finally receiving sound wave.
In specific implementation process, exist be initially received the microphone 11 of sound wave there are two the case where.In such cases,
Orientation residing for sound source is close to the centre of two microphones 11.In practice, there is also the microphones 11 for finally receiving sound wave two
A situation.In such cases, centre of the orientation residing for sound source far from two microphones 11.
In another scheme, the information of acoustic wave received includes the volume of sound wave.Fig. 5 is the intelligent sound box in Fig. 1
The schematic diagram of auditory localization is carried out according to the sound wave volume that microphone receives.Specifically, referring to Figure 5, eight wheats
In gram wind 11：The sound wave volume that the microphone 11 nearest apart from sound source receives is maximum；Microphone 11 apart from next, receives
Sound wave volume decrease；The microphone 11 of distance thirdly, the sound wave volume received decrease again；Inverse distance
Two remote microphones 11, the sound wave volume received are second from the bottom small；Apart from farthest microphone 11, the sound wave volume that receives
It is minimum.As can be seen that orientation residing for sound source is close to receiving the maximum microphone 11 of sound wave volume, far from receiving sound wave sound
Measure minimum microphone 11.
In specific implementation process, exist receive the maximum microphone of sound wave volume 11 there are two the case where.Such feelings
Under condition, the orientation residing for sound source is close to the centre of two microphones 11.In practice, there is also the Mikes for receiving sound wave volume minimum
The case where there are two wind 11.In such cases, centre of the orientation residing for sound source far from two microphones 11.
After accurate positionin, the user speech acquisition system in intelligent sound box 1 can carry out targetedly in the orientation of sound source
Orientation acquires, to improve voice collecting precision；In intelligent sound box 1 sound generating mechanism (it is shown in Figure 1, be located at barrel
A circle loudspeaker on the lower, do not identify) can also selectively sounding, sound wave is sent to targetedly orientation, to reduce energy consumption
And improve user's auditory effect.
Although present disclosure is as above, present invention is not limited to this.Any those skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
