Fig. 2 is a kind of flow chart of sound playing method according to another exemplary embodiment, the sound broadcasting side Method can be applied to equipped with the terminal of detection components, the terminal both can be mobile phone, tablet personal computer, laptop computer, The mobile terminal handy to carry about such as MP3/MP4, point reader, electric paper book or Intelligent bracelet, intelligent glasses, intelligence The wearable smart machines such as wrist-watch, intelligent accessories, it can also be equipped with TV, PC or Baffle Box of Bluetooth apart from detection components etc. Terminal, the sound playing method can include the following steps：

In step 201, the front of detection terminal is with blocking the distance between object.

The front of detection terminal can be embedded in terminal apart from detection components completion with blocking the distance between object , this can be one group of component that can receive and dispatch ultrasonic signal or infrared distance measurement component apart from detection components.

For the time is upper, the front of detection terminal can periodically detect with blocking the distance between object, example As detected the front of a terminal per 50ms with blocking the distance between object.The detection cycle can be according to detection sensitivity Height determines, if such as want to make detection sensitivity higher, shorten detection cycle；If thinking, another detection sensitivity is lower, The then growth detection cycle.

Or terminal using can be plugged in terminal apart from detection components measuring terminals front with block object it Between distance.

Wherein, following scheme can with blocking the distance between object using the front of ultrasonic signal detection terminal Realize.In this case, the component for receiving and dispatching ultrasonic signal is a sound releasing unit and a microphone unit.First, Front side emitter first acoustic signals of the sound releasing unit of terminal to terminal；Afterwards, the microphone unit of terminal receives first Acoustic signals reach the second acoustic signals of testee back reflection；Finally, terminal is according to the emission parameters of the first acoustic signals The distance between the front of the reception parameter computing terminal of second acoustic signals and testee.

In implementation process, the emission parameter of the first acoustic signals of terminal and the reception parameter of the second acoustic signals can be with It is different parameters, different parameters corresponds to different measurement situations, introduces two kinds of modes in the cards herein, division is such as Under.

(1) the acoustic signals amplitude for receiving parameter and emission parameter when including transmitting-receiving respectively.

In this implementation, first, terminal is launched when detecting that terminal starts distance measurement function by the sound of terminal Front side emitter first acoustic signals of the unit to terminal.

So that terminal is mobile phone as an example, start after specifying function to refer to the function that handset starting needs to measure distance, terminal The acoustic signals of front side emitter first from sound releasing unit to the terminal, the front of the terminal refer to terminal with touch screen and Receive the one side of user's touch operation.For example, face where the screen of smart mobile phone is the front of terminal.Now, sound transmitting is single Member faces out the first acoustic signals of transmitting from one where mobile phone screen.

Alternatively, the first acoustic signals can be ultrasonic signal.Wherein, due to the direction signal collection of ultrasonic signal In, thus positive this determination direction transmitting acoustic signals to terminal for being adapted to the embodiment of the present disclosure to provide.Ultrasonic signal Frequency do not limit here, frequency more than 20KHz sound wave can be achieved the embodiment of the present disclosure shown by scheme, frequency can To be 96KHz, 128KHz or 256KHz etc..

Alternatively, the sound releasing unit is the receiver at the top of terminal.

Fig. 3 is refer to, Fig. 3 is a kind of schematic diagram for terminal that the embodiment of the present disclosure is related to.The terminal includes sound hair Penetrate unit 31 and microphone unit 32.

Secondly, the second sound wave of the first acoustic signals arrival testee back reflection is received by the microphone unit of terminal Signal.

It is tested that the terminal receives first acoustic signals arrival after the first acoustic signals are launched, by microphone unit The second acoustic signals after object reflection.Second acoustic signals are that the first acoustic signals run into the formation of testee back reflection, There is identical frequency with the first acoustic signals, because residing propagation medium is identical after reflection, therefore the second acoustic signals and first The spread speed of acoustic signals is also identical.

Alternatively, the microphone unit is the noise reduction microphone at the top of terminal.Herein the position of the microphone unit with it is upper State that the position of sound releasing unit is corresponding, the order of magnitude of the scheme measuring accuracy provided due to the embodiment of the present disclosure is centimetre Level and ultrasonic wave can be considered as along straightline propagation when measuring short distance, therefore designs the sound releasing unit and the microphone unit Position when, should by the installation site between it as close to.Therefore when sound releasing unit is located at terminal top, it is used for Receiving the microphone unit for the reflection wave signal that sound releasing unit launches ultrasonic signal should be arranged on away from its close position Put.Alternatively, the scope of the distance between the noise reduction microphone unit and sound releasing unit within one centimetre.

Alternatively, the position of sound releasing unit and microphone unit can also be arranged in the other positions of terminal, and two The position of person also should be as close as.

Again, between amplitude when amplitude and the second acoustic signals when the first acoustic signals of calculating are launched are received Amplitude difference.

When acoustic signals are propagated in medium (air), the decay of energy is decided by the diffusion, scattering and suction of acoustic signals Receive.In perfect medium, the decay of sound wave comes solely from the diffusion of sound wave, i.e., the distance propagated with acoustic signals increases and caused The decrease of sonic energy signal.When scatter attenuation refers to that ultrasonic wave is propagated in media as well, granular boundary or stream in solid dielectric Suspended particles in body medium make sound wave produce diffraction, and a portion acoustic energy no longer moves along the original direction of propagation, and is formed Scattering.The shape of scatter attenuation and scattering particles, size, quantity, the property of the property of medium and scattering particles are relevant.Absorption declines It is due to medium viscosity to subtract, and ultrasonic wave is caused the interior friction between particle when propagating in media as well, so that a part of acoustic energy Heat energy is converted to, heat exchange is carried out by heat transfer, causes the loss of sonic energy signal.Fig. 4 is refer to, Fig. 4 is the disclosure A kind of decay schematic diagram for acoustic signals amplitude that embodiment is related to, in Fig. 4 the amplitude of acoustic signals with propagation distance increasing Add and reduce.In Fig. 4, A represents the amplitude of acoustic signals, and D represents propagation distance.It should be strongly noted that sound wave shown in Fig. 4 A kind of the graphical of damped manner of the amplitude for being reduced to acoustic signals of signal amplitude schematically illustrates, not to the decay of sound wave Mode forms restriction.

When first acoustic signals are launched, its emission parameter will be recorded in the terminal.Wherein, emission parameter includes first Amplitude when acoustic signals are launched, the average amplitude value when amplitude can be the transmitting of the first acoustic signals, or or First acoustic signals are starting the instantaneous amplitude value of emission time.

Similarly, when the second acoustic signals are received, it receives parameter and will be recorded in the terminal, and the reception parameter includes the Amplitude when two acoustic signals receive, the amplitude can be average amplitude values when the second acoustic signals receive, or can also It is that the second acoustic signals are terminating the instantaneous amplitude value of the time of reception.

Exemplified by the first acoustic signals by sound releasing unit transmitting are 96KHz ultrasonic signals, due to the ultrasonic wave After signal is launched, the amplitude of sound wave is gradually reduced with the increase of propagation distance in atmosphere, the ultrasonic signal it is flat Equal acoustic density is also gradually reduced.Therefore, the amplitude and the first acoustic signals for the second acoustic signals that microphone unit receives The distance that is propagated through of amplitude variations difference and above-mentioned two acoustic signals into positive correlation.The amplitude of second acoustic signals and The amplitude variations difference of one acoustic signals is bigger, and terminal and the distance between testee are longer.

Then, the ambient parameter of terminal surrounding is obtained by the environmental sensor in terminal, ambient parameter includes temperature, sky At least one of air humidity degree or air pressure.

The speed that the amplitude of sound wave is decayed in media as well depends on attenuation coefficient when sound wave is propagated in the medium, and this declines It is relevant to subtract the factors such as coefficient and the material, temperature and density of medium.In this implementation, the first acoustic signals and the rising tone Ripple signal is propagated in atmosphere, and for air, it, which influences the factor of the attenuation coefficient of sonic wave amplitude, mainly includes temperature Degree, air humidity and air pressure etc., therefore, in this implementation, terminal can obtain terminal by environmental sensor first Surrounding includes the ambient parameters such as temperature, air humidity and air pressure.

Then, the attenuation coefficient of amplitude in propagation process of sound wave is obtained according to ambient parameter.

At least one of the temperature, air humidity or the air pressure that are obtained according to above-mentioned measurement ambient parameter, terminal can foundations The corresponding relation pre-set obtains attenuation coefficient.Attenuation coefficient can be according to three said temperature, air humidity and air pressure surveys Value and obtain, can also be obtained according to wherein at least one measured value.

Attenuation coefficient, in addition can without the ambient parameter of measurement in the case of being obtained according to wherein at least one measured value Use preset value.For example, only measure temperature, then air humidity and the corresponding preset value used at this temperature of air pressure.

Then, according to the distance between amplitude difference and the front of attenuation coefficient computing terminal and testee.

In a kind of computational methods in the cards, terminal prestores a list, in the list comprising attenuation coefficient, Corresponding relation between the data of three kinds of the distance between the front of amplitude difference and testee away from terminal, in the list processing side Attenuation coefficient and amplitude difference are continuous value in method, to ensure that the data of a pair of attenuation coefficients and amplitude difference can correspond to Find the distance between the front of testee away from terminal.

A user is prestored in the computational methods of alternatively possible realization, in terminal according to amplitude difference and decay Coefficient calculates the formula in the distance between front of the testee away from terminal, and the formula can be with burning some chip in the terminal In or an integrated application program in the terminal in, using the formula, terminal only needs to input independent variable attenuation coefficient And amplitude difference, you can to obtain the distance between the front of testee away from terminal.

In another computational methods in the cards, terminal can be according to the amplitude of first acoustic signals, according to phase Conversion relation is closed, obtains the acoustic pressure and the sound intensity of the first acoustic signals, and according to the amplitude of the second acoustic signals, converted according to correlation Relation obtains the acoustic pressure and the sound intensity of the second acoustic signals, then together brings the attenuation coefficient obtained in step 205 into formula respectively In (1-1) and formula (1-2).

P₂=P₁e^-kx (1-1)

I₂=I₁e^-2kx (1-2)

Wherein, P₁It is the acoustic pressure of the first acoustic signals, P₂It is the acoustic pressure of the second acoustic signals；I₁It is the first acoustic signals The sound intensity, I₂It is the acoustic pressure of the second acoustic signals；K is attenuation coefficient, and x is the distance between the front of testee away from terminal.

Then, according to above-mentioned formula (1-1) and formula (1-2) can calculate between front of the testee away from terminal away from From x.

Alternatively, the terminal can be measured by continuously sending continual acoustic signals by multiple acoustic signals Aggregation of data draws the distance between the front of testee away from terminal, such as to multiple distance values within nearest a period of time Average as the distance between the front of testee away from terminal.Each acoustic signals quilt that sound releasing unit is sent Add a bit of code and form mark, when microphone unit receives the second acoustic signals, terminal can be believed according to the second sound wave The mark in number is come corresponding with each acoustic signals that sound releasing unit is sent.For example, sound releasing unit is continuously sent The mark of acoustic signals institute band be respectively：A₁、A₂、A₃……A_n, then can be according to A during microphone unit reception acoustic signals₁、 A₂、A₃……A_n, wait mark corresponding with the signal launched, for example terminal is A in sound releasing unit emission mark₁'s One group of parameter is have recorded during signal, and is received in microphone unit and is labeled as A₁Signal when have recorded another group of data, now This two groups of data are corresponding data, using this two groups corresponding parameters can draw between a front of the testee away from terminal away from From.At the same time, parameter when parameter when terminal launches the acoustic signals of other marks and reception corresponds, will be default The distance between the front of multiple testees away from terminal that the data of group number are calculated is averaged, or uses other numbers The distance between the front of testee away from terminal is drawn according to processing method, is surveyed with reaching using continuous continual acoustic signals The distance between the front of testee away from terminal, avoid because being brought when indivedual sound waves are interfered to whole measurement result The effect of error.

(2) at the time of reception when parameter and emission parameter include receiving and dispatching respectively.

So that terminal is mobile phone as an example, start after distance measurement function refers to the function that handset starting needs to measure distance, terminal The acoustic signals of front side emitter first from sound releasing unit to the terminal, the front of the terminal refer to terminal with touch screen and Receive the one side of user's touch operation.For example, face where the screen of mobile phone is the front of terminal.

Alternatively, the sound releasing unit is the sound transmitting at the top of terminal.

It is tested that the terminal receives first acoustic signals arrival after the first acoustic signals are launched, by microphone unit The second acoustic signals after object emission.Second acoustic signals are that the first acoustic signals run into the formation of testee back reflection, There is identical frequency with the first acoustic signals, because residing propagation medium is identical after reflection, therefore the second acoustic signals and first The spread speed of acoustic signals is also identical.

Alternatively, the microphone unit is the noise reduction microphone at the top of terminal.The position of the microphone unit is above-mentioned herein The position of sound releasing unit is corresponding, because the order of magnitude of the scheme measuring accuracy of embodiment of the present disclosure offer is Centimeter Level And ultrasonic wave can be considered as along straightline propagation when measuring short distance, therefore design the sound releasing unit and the microphone unit During position, should by its installation site as close to.It is located between tut transmitter unit at the top of terminal, therefore for receiving sound The microphone unit that sound transmitter unit launches the reflection wave signal of ultrasonic signal should be arranged on away from its proximity.

Alternatively, the position of sound releasing unit and microphone unit can also be arranged in the other positions of terminal, and two The position of person should be as close as.

Include emission time when the first acoustic signals are launched, the rising tone in the emission parameter of first acoustic signals When the reception parameter of ripple signal includes time of reception when the second acoustic signals are received, subsequent operation is performed.

Again, when calculating reception when emission time when the first acoustic signals are launched is received with the second acoustic signals Time difference between quarter.

When first acoustic signals are launched, its emission parameter will be recorded in the terminal.The emission parameter includes the first sound The emission time during transmitting of ripple signal.

Similarly, when the second acoustic signals are received, it receives parameter and will be recorded in the terminal.The reception parameter includes the Time of reception when two acoustic signals are received.

Time of reception when being received according to the emission time during transmitting of the first acoustic signals and the second acoustic signals Difference, obtain time difference T.

The ambient parameter for the terminal surrounding that terminal is obtained by environmental sensor, ambient parameter include temperature, air humidity Or at least one of air pressure.Temperature, air humidity or effects of air pressure atmospheric density, and atmospheric density influences sound wave in atmosphere Spread speed, the spread speed of the more high then ultrasonic wave of density of air is faster, thus want obtain sound wave spread speed Environmental sensor need to be first passed through and obtain ambient parameter.

Then, the spread speed of sound wave is obtained according to ambient parameter.

After the measurement of the above-mentioned ambient parameter including to temperature, air humidity or air pressure, determine the first acoustic signals and The aerial spread speed V of second acoustic signals.

Then, the distance between front and testee of terminal are calculated according to time difference and spread speed.

Can be according to formula D=T*V/2, wherein D represents testee away from the distance between terminal, and T represents the first sound wave letter Number transmitting when time of reception when being received of emission time and the second acoustic signals difference, V represents the first acoustic signals With the aerial spread speed of the second acoustic signals.

Perform complete step 201 after, can according to the terminal front with this block the distance between object determination sound Symbol, the step can be realized by performing step 202 and step 203 successively.

Wherein, the distance between object is blocked with this according to the front of the terminal and determines note, can be according to the terminal Front and block the vertical range between object to determine note, or according to the front of the terminal and block between object The distance of a certain fixed-direction determine note.Fig. 5 is refer to, Fig. 5 is that one kind according to an exemplary embodiment is whole Schematic diagram of the front at end with blocking the distance between object.Fig. 5 is the left view in terminal and the three-view diagram for blocking object.51 It is terminal, 52 to block object, 511 be the front of terminal, 521 is to block positive nearest one side of the object away from terminal, 53 are Vertical range between 511 to 521,54 be the predetermined direction (shown in dotted line) the distance between 511 to 521 along Fig. 5.

In addition, the shape for blocking object can be bluff body, cylinder, polyhedron or irregular polyhedronses.Block object institute Blocking position be in measurement range of the terminal apart from detection components, if terminal measurement distance component is ultrasonic transmission/reception group Part, then block object and be in directly over ultrasonic transmitting-receiving subassembly in a reverse taper space, the vertex of a cone of the reverse taper is received for the ultrasonic wave Send out component；If terminal measurement distance component is infrared distance measurement component, this block object be in the infrared distance measurement component before, can Block the position of the ray of infrared distance measurement component transmitting.

In step 202, determine the terminal front with this block the distance between object place apart from section.

Refer to Fig. 6, Fig. 6 be a kind of front of terminal according to an exemplary embodiment and block between object away from The interval division schematic diagram from a distance from.61 represent the front of terminals where plane, 621~628 represent respectively distance 61 it is different away from From plane.Wherein, the distance of two interplanars adjacent in 621~628 can be between equal such as adjacent 621 and 622 Distance be that the distance between m, 622 and 623 is that the distance between m ... 627 and 628 is m, now the distance between 61 to 621 For n.Then the distance between 61 to 621~628 ask respectively：N, (n+m), (n+2m), (n+3m) ... (n+6m) and (n+7m).

Plane 61 to plane 628 is divided into eight apart from section by above-mentioned 621~628, and this eight are respectively apart from section (0, n], (n, n+m], (n+m, n+2m] ... (n+5m, n+6m] and (n+6m, n+7m].Object and terminal are blocked whenever getting After the distance between plane 61 L where positive, the numerical intervals where the L are detected.Such as L ＞ (n+2m) and L ＜ (n+3m), then Determine L be located at section (n+2m, n+3m] in, the section blocked where the distance between front of object and terminal is (n+2m, n+ 3m]。

Alternatively, two plane distances adjacent in 621~628 can be with unequal, between each two adjacent plane Distance can be configured according to size set in advance.

In step 203, according to this apart from section, and the corresponding relation between section and note prestored Inquire about note.

The corresponding relation between section and note prestored can be one-to-one relationship, i.e. a distance regions Between a corresponding note.According to the section divided in Fig. 6, can be (n, n+m], (n+m, n+2m] ... (n+5m, n+6m] and (n+ 6m, n+7m] seven sections correspond to seven 1 (do), 2 (re), 3 (mi), 4 (fa), 5 (sol), 6 (la) and 7 (si) sounds respectively Symbol.

If the front of terminal to block the distance of object section (n+5m, n+6m] in, then note corresponding to the distance is 6 (la)。

In step 204, sound to be played is generated according to the note of determination and preset tones.

Wherein, the note of the determination is the note that above-mentioned steps 203 inquire.Terminal can according to the note of determination, The type of default tone and musical instrument to be simulated generates the sound of corresponding musical instrument, such as, when musical instrument to be simulated is steel Qin, then generation correspond to the piano sound of above-mentioned note and tone；Or when when the musical instrument simulated is guitar, then generation it is corresponding on State the guitar sound of note and tone.

In step 205, the sound to be played is played.

Terminal can use the horn assembly of itself to play sound or terminal control ratio that abovementioned steps are determined Such as other electronic equipments for being capable of sounding of Baffle Box of Bluetooth play sound.Play sound mode can be measure block object with Play or sequentially played after the note of predetermined number is determined immediately after distance between the front of terminal.It is for example, pre- If the note of quantity is 30, after terminal determines 30 notes, sound corresponding to 30 notes is sequentially played.

Optionally, in the disclosed embodiments, the distance between object is blocked with this when the front of the terminal to change And beyond this apart from section when, note is determined according to the front of the terminal and the distance blocked after changing between object.

Wherein, the front of above-mentioned terminal and the distance blocked after changing between object have two kinds of possible situations.Situation One：User needs to generate sound corresponding to two adjacent notes.Situation two：User needs to generate two non-conterminous notes pair The sound answered, or, user needs to generate sound corresponding to two identical notes.

In situation one, if the front of terminal changes and beyond this apart from section with the distance between object is blocked When, now object is blocked still in the measurement range apart from detection components of terminal apart from section beyond this.For example, terminal Front and block before the distance between object changes section (n+5m, n+6m] in, corresponding note is 6 (la)；Afterwards Block the distance between front of object and terminal shortening so that the distance change after section (n+4m, n+5m] in, then Now according to section (n+4m, n+5m] find corresponding to note 5 (sol).

In situation two, if terminal front and block the distance between object change and more than apart from section when, Now object is blocked not in the measurement range apart from detection components of terminal, afterwards not in the terminal apart from section beyond this The measurement range apart from detection components in the object that blocks again return in the measurement range apart from detection components.For example, Terminal front and block before the distance between object changes section (n+5m, n+6m] in, corresponding note is 6 (la)；The measurement range apart from detection components that object leaves terminal is blocked afterwards, again returns to the range measurement section of terminal (n+5m, n+6m] (such as the horizontal detection range for removing terminal front side of object, the detection of terminal front side is then moved horizontally into again Scope), now corresponding note is still 6 (la)；Or block object return terminal range measurement section (n+2m, n+3m], Now corresponding note is 3 (mi).
