Further, space length detection is no less than three times the detection of enclosure space volume.In order to more The accurate volume (approximate volumes) for determining enclosure space.

For present disclosure, a more detailed description will be made below:

(1) in the locating enclosure space that sound pick-up detects after the waveform of one section of sound, by waveform conversion module by the sound Waveform is converted to as initial sample, then sound pick-up continues to the sound of locating enclosure space, due under normal circumstances, Sound in enclosure space be it is complicated, changeable, so the sound waveform that sound pick-up is included be also it is continually changing, be embodied in It is exactly the sine wave continuously constantly to rise and fall in waveform diagram.Due to the structure (wall of such as one meeting room in enclosure space Body etc.) there is reflex to sound, then will necessarily receive detecting in the regular hour after initial sample with phase With the sound wave of wave function.When detecting the waveform for occurring above sound for the second time, it is stored as the second sample, initial sample Interval time with the second sample is as first time interval value；When third time detects the waveform for above sound occur, by it It is stored as third sample, the interval time of initial sample and third sample is as the second time interval value；It detects for 4th time When stating the waveform of sound, it is stored as the 4th sample, the interval time of initial sample and the 4th sample is as between the third time Every value.Then according to the aerial spread speed of sound, sample distance measurement module is according to physical equation: distance=speed multiplies With the time, first time interval is carried out apart from meter in subaerial spread speed 340m/s (air, 25 DEG C) in conjunction with sound It calculates, the second time interval is carried out carrying out showing that three groups of sound pick-ups are received apart from calculating to third time interval apart from calculating With the distance between the consistent sound of initial sample and reverberation (wall) numerical value, by these three distance values carry out stereometer It calculates, the approximate volume (or approximate volumes) of enclosure space, above-mentioned spatial volume (approximation where can obtaining sound pick-up Product) a kind of a reference value one as spatial measurement system.Meanwhile the sonic wave amplitude screening module of software systems transmits sound pick-up All sound waveforms, counted with the wave frequency of occurrence of the wave frequency of occurrence of the high amplitude in chronomere and short arc, Take wave more than frequency of occurrence as main basis, software systems according to mainly according to a reference value two as spatial measurement system, Software systems are adjusted the volume of the loudspeaker according to a reference value one and a reference value two.

(2) in conjunction with attached drawing 4, the calculation of sound receiving time is as follows: first, it is assumed that sound pick-up to sound producing body away from From for x1, the distance for reflecting metope to sound producing body is x2, and the distance of sound pick-up to reflection metope is x0, velocity of sound v, sound pick-up The time for receiving the sound sending of generating device is t1；The time of sound to reverberation is t2.Then have: x0=x1+x2, x1=v* t1,x2=v*t2,x0=(t1+t2)*v.It follows that x0 is proportional to (t1+t2), (t1+t2) is exactly that sound is picking up in other words A time it takes is run between sound device and reflection metope.If regarding t2 as a benchmark, then sound is reflected from wall It is t1+t2 to the time used in sound pick-up position, such as sound pick-up and sounding device be in same position (i.e. t2=0), then reflected sound The time that sound reaches sound pick-up present position is t1.Similarly it follows that t1+t2 is exactly to be transported on sound pick-up to reverberation with the velocity of sound Time T required for dynamic.And this time T is exactly that sound pick-up receives first sample, again after receiving initial sample The interval time of two samples, third sample and the 4th sample.

(3) in conjunction with attached drawing 2, waveform sample sampling method is as follows: since first waveform for receiving sound, with one A certain number of single waves are recorded in chronomere for sample, for example, with three continuous wave crests for a sample unit, From 1. a wave crest start recording, first three wave crest is recorded as initial sample, wave crest 1., wave crest 2., wave crest 3..Likewise, Second record sample, and with continuous three wave crests for a sample, from the second wave crest start recording received, That is, is 2. a, it is 3. a, 4. a wave crest be recorded as second sample, and be compared with initial sample.Third time record sample This is from third wave crest start recording, and the 3. 4. 5. a wave crest is recorded as third sample for a wave crest, for a wave crest, the, and with Initial sample is compared, and so on.By comparing, the 4. 5. 6. a wave of a wave crest, the of a wave crest, the of the of the 4th sample 1. 2. 3. the spacing of a wave crest is equal for a wave crest, for a wave crest, for the spacing at peak corresponding with initial sample, also, the 4th The of secondary sample 1. a wave crest, 2. a wave crest, 3. the height ratio of a wave crest corresponding with initial sample 1. a wave crest, The height ratio of the 2. 3. a wave crest of a wave crest, is consistent, but the height of three wave crests of the 4th sample is below initial sample The height of three wave crests, therefore the 4th sample is defined as the second sample, that is, the 1st wave crest of the 4th sample is corresponding just 1st wave crest of beginning sample, the 2nd wave crest of the 4th sample correspond to the 2nd wave crest of initial sample, and the of the 4th sample 3 wave crests correspond to the 3rd wave crest of initial sample, that is, the ratio of three wave crests of the 4th sample is equal to initial sample The ratio of three wave crests is wave crest 1: wave crest 2: wave crest 3.In this approach, third sample, the 4th sample are found out.Sample above takes The sample time according in sample crest amplitude wave occur time subject to.When choosing sample, the frequency of sound wave of selected waveform with The frequency of sound wave of initial sample is identical, and since sound is in communication process, after the reflection of wall, energy is had Reduced, show be exactly in waveform diagram wave crest (amplitude) change.

(4) Fig. 1 is combined, the working method of sonic wave amplitude screening module is as follows: sonic wave amplitude screening module receives sound wave After data, the characteristics of with unit time length analysis sound wave, high amplitude waveform and short arc waveform are screened out, high amplitude waveform is again The waveform of high density high amplitude wave and the waveform of low-density high amplitude wave are screened out, short arc waveform screens out the low vibration of high density again The waveform of amplitude wave and the waveform of low-density short arc wave, then screen out the waveform and high density short arc wave of high density high amplitude wave Waveform be passed to Bomi degree Screen assemblies, screening selects the wave of high density amplitude, standby for storage element two and storage element three With.The wave crest of the wave crest of high density high amplitude wave and high density short arc wave wave is compared, takes by comparing by software systems The wave crest of high density amplitude takes the wave crest of low-density amplitude as secondary basis, by the amplitude of main basis as main basis Value is spare as the deposit storage element two of a reference value two.Meanwhile by the waveform and low-density Gao Zhen of the high density amplitude screened out The waveform of amplitude wave merges, and it is spare to be stored in storage element three as a reference value three.About a reference value two: sound pick-up is transmitted to software All sound waveforms of system, are measured, while measuring short arc by the quantity of the high amplitude sound wave occurred in the unit time The quantity of sound wave, high amplitude sound wave frequency of occurrence and short arc sound wave frequency of occurrence carry out statistics calculating, take more than frequency of occurrence Sonic wave amplitude value is as main basis, and the sonic wave amplitude value for taking frequency of occurrence few is as secondary basis, and software systems are according to main According to a reference value two as spatial measurement system.Main basis and secondary basis are a pair of data mutually to compare, when unit In take the wave more than frequency of occurrence to be main basis, the wave for taking frequency of occurrence few is secondary basis, that is, density is big in the unit time Wave be main basis, the small wave of density be secondary basis.The occurrence of main basis according to all waves in high amplitude set wave In the average value and short arc set of peak heights subject to the average value of the crest height of all waves.

A reference value one is used to measure the size in space, to determine the max volume value of loudspeaker；A reference value two measures this The sound scenery classification in a space, such as meeting, two people or more people talk, the machine sound of factory etc., these sound sound Situation determines the minimal volume value of loudspeaker, determines the minimum volume of loudspeaker with a reference value two, be for convenient for prominent prompt tone with Alert device user；After a reference value three is judged as conference model, speaker volume is defined as not sounding.

(5) Fig. 2, high amplitude sound wave and short arc sound wave partitioning standards are combined are as follows: the crest amplitude sound wave in chronomere Height value and lowest amplitude sound wave height value difference divided by 2, (the height value of crest amplitude sound wave-lowest amplitude sound wave Height value) ÷ 2+ lowest amplitude sound wave value, this numerical value obtained is exactly the boundary for dividing high amplitude sound wave and short arc sound wave Line.The wave that sound wave crest height is higher than line of demarcation is referred in high amplitude sound wave set, sound wave crest height is lower than line of demarcation Wave be referred in short arc sound wave set.The result that sonic wave amplitude Screen assemblies obtain, that is, a reference value two is for limiting loudspeaking The minimum value of device volume.Two numerical value of a reference value is smaller, and speaker volume is smaller.

(6) scene mode of default set in the present invention is divided into three kinds: conference model, indoor mode, outdoor mode.

As shown in figure 3, software systems are detecting that locating space is a smaller space, and someone says incessantly Language, it is conference model that software systems, which just define current scene, issues the loudspeaker instruction that sounding is not rung, or only issue and mention Show the instruction of flick of lamp；

Software systems are detecting that locating space is a smaller space, and voice, or detection is not detected in certain time To language if more people, it is indoor mode, prompt tone sound as defined in loudspeaker sending system that software systems, which just define current scene, Amount, this volume are gradually changed from small to big according to the beginning of a reference value two to volume as defined in a reference value one；

Software systems are detecting that locating space is a larger space, and software system defines current scene just as outdoor mould Formula, minimum prompt tone volume are subject to a reference value two and start to become larger, and maximum prompt tone volume is unrestricted, until loudspeaker is hard Part max volume.Such as under outdoor mode, the volume of loudspeaker is gradually increased to 100% by 25%, the bigger loudspeaking of a reference value two The minimum volume of sound that device issues is bigger.Indoors under mode, the volume of loudspeaker is gradually increased to 25%, but double bass by 1% Amount has the decision of a reference value two.1%, 25%, 100% in Fig. 5 be this specification be convenient for explaining numerical value proposed by the invention, it is real When border is designed, it is arranged according to actual requirement.

(7) decision condition of scene mode: (1) conference model: a reference value one measures sound pick-up place spatial volume and is 100m3~500m3, and this value has not been changed long, for example does not change in three minutes, a reference value two it is main according to variation Amount fluctuates in smaller range.(2) indoor mode: spatial volume where a reference value one measures sound pick-up is 100m3~500m 3, and this value has not been changed long, for example does not change in three minutes, a reference value two it is main according to variation in larger model Enclose interior fluctuation.(3) outdoor mode: a reference value one not can be measured spatial volume where sound pick-up, that is, only detect initial sample This, is not detected other samples.

After mobile phone enters another space or after ambient sound changes, because system is constantly in space inspection Survey state, after detecting that space changes, system issues corresponding instruction to audio system immediately, is receiving mobile phone When the information voice that new incoming call, short message or other APP are sent, the sound of appropriate volume is issued.This voice prompt can Cellie is reminded, and it is too small and fail to notify the equipment users such as mobile phone to be unlikely to volume, and it is excessive to be also unlikely to volume And influence other people.

A reference value one changes or a reference value two changes, and software systems can all issued and changes original loudspeaker Volume instructions, that is, when a reference value one changes, software systems change maximum prompt tone volume, when a reference value two changes When change, software systems change minimum prompt tone volume.
