Wherein, default sampling length, can be set as needed.Such as, can be receivable etc. according to user Treat that the conditions such as time, the conversion speed for sending terminal are configured.When user is badly in need of transmitting data using acoustic communication, It can set with 100ms (millisecond), 500ms etc. shorter sampling length collection is sent in the environment that terminal is presently in Voice signal.Or, when sending the conversion speed of terminal quickly, the longer sampling with 3s, 5s etc. can be set Length collection sends voice signal in the environment that terminal is presently in, etc..

It should be noted that because the voice signal in environment not in the same time is typically different, therefore, of the invention real Apply in example, can periodically gather the voice signal sent in the environment that terminal is presently in.

In addition, in embodiments of the present invention, sending terminal can be clicked in user, be slided etc. after touch control operation, with Default sampling length, collection sends the voice signal in the environment that terminal is presently in.Or, it can also be needed in user When, for example, when user starts the application for needing to be communicated by sound wave, automatic data collection sends the ring that terminal is presently in Voice signal in border, to be parsed to the voice signal collected, it is determined that the environment that transmission terminal is presently in is corresponding First audio frequency characteristics and first object frequency group.

Accordingly, before step 101, it can also include：

Default application is started it is determined that sending in terminal；

Or,

Default process is started it is determined that sending in terminal.

When implementing, can according to application or process type, predefine need carry out acoustic communication application or The corresponding mark of process, so that after it is determined that starting application corresponding with default mark or process in transmission terminal, you can With default sampling length, collection sends the voice signal in the environment that terminal is presently in.With to the voice signal collected Parsed, it is determined that sending corresponding first audio frequency characteristics of environment and the first object frequency group that terminal is presently in.

The specific process for determining to send the corresponding first object frequency group of environment that terminal is presently in, will be in following realities Apply in example and describe in detail, be not illustrated herein.

In addition, determining to send the process for corresponding first audio frequency characteristics of environment that terminal is presently in, it is referred to existing Technology, here is omitted.

Step 102, first data transmission request is sent to server, it is special that first data transmission request includes the first audio Levy and first object frequency group.

Specifically, sending terminal determines corresponding first audio frequency characteristics of the environment being presently in and first object frequency group Afterwards, you can first data transmission request is sent to server, so that server first data transmission is asked to include the One audio frequency characteristics and first object frequency group are sent to receiving terminal.And make receiving terminal according to the first audio frequency characteristics, the first mesh Corresponding 3rd audio frequency characteristics of environment where marking frequency group, and receiving terminal and the 4th target frequency group, carry out information matches, from And when the match is successful for the first audio frequency characteristics and first object frequency group and the 3rd audio frequency characteristics and the 4th target frequency group, to clothes Business device returns to the message for confirming matching.

In a kind of possible way of realization, also include in first data transmission request：Send terminal is currently located the One positional information.So that server determines corresponding receiving terminal first according to first position information.

Step 103, the data transfer enabled instruction that the reception server is issued.

Step 104, it is modulated using first object frequency group to sent data, generates acoustic signals.

Step 105, acoustic signals are sent.

Specifically, receiving terminal determines corresponding first audio of environment that server is sent, transmission terminal is presently in Feature and first object frequency, the 3rd audio frequency characteristics corresponding with the environment that receiving terminal is presently in and the 4th target frequency group During matching, you can send confirmation message to server, so that server is that can determine that can be between transmission terminal and receiving terminal Carry out data transmission, and data transfer enabled instruction is sent to terminal is sent.

Send terminal to receive after the data transfer enabled instruction that server is issued, you can utilize first object frequency group pair Data to be sent are modulated, and generate acoustic signals, and the acoustic signals of generation are sent into receiving terminal by loudspeaker.

The specific process being modulated using first object frequency group to sent data, prior art has been related to And, here is omitted.

Or, send terminal and corresponding first audio frequency characteristics of the environment being presently in and first object frequency group is determined Afterwards, you can first data transmission request is sent into server, so that server is according to the first audio frequency characteristics and first object frequency Point group, judges the first audio frequency characteristics and first object frequency group the 3rd audio frequency characteristics whether corresponding with environment where receiving terminal And the 4th target frequency group matching.If matching, server, which can determine to send between terminal and receiving terminal, can enter line number Data transfer enabled instruction is sent according to transmission, and to terminal is sent.The data biography that server is issued is received so as to send terminal After defeated enabled instruction, you can be modulated using first object frequency group to sent data, acoustic signals are generated, and will be raw Into acoustic signals receiving terminal is sent to by loudspeaker.

It should be noted that in embodiments of the present invention, transmission terminal can also be pre-set and sending the to server After a period of time of one data transfer request, directly it is modulated, is generated to sent data using first object frequency group Acoustic signals, and the acoustic signals of generation are sent to receiving terminal by loudspeaker, without that must be sent out in the reception server The modulation and transmission of acoustic signals are carried out after the data transfer instruction sent again, you can to omit step 104, led to so as to improve sound wave The efficiency of letter.

It should be noted that in embodiments of the present invention, for the privacy of data transfer, before step 104, may be used also To be encrypted to sent data, so as to improve the safety and reliability of data transfer during acoustic communication.

Specifically, the key being encrypted to sent data, can be affiliated respectively by transmission terminal and receiving terminal User input.Wherein, the key of user's input can be determined by user by oral negotiation, or, can also be direct According to default rule, the mark of receiving terminal, id etc. are set to key, the present embodiment is not limited this.

For example, data to be sent are encrypted using the mark of receiving terminal if sending terminal, so that many Individual receiving terminal is received sends after the acoustic signals that terminal is sent, and only legal receiving terminal is using its mark to getting After data are decrypted, accurate data can be obtained；And illegal receiving terminal, it is impossible to obtain accurate using its mark decryption Data, so as to ensure that data are only transmitted that there is provided data transfer sending between terminal and legal receiving terminal Safety and reliability.

It is understood that in a kind of possible way of realization of the embodiment of the present invention, according to the transmission terminal collected Voice signal in the environment being presently in, it is determined that first object frequency group in frequency negligible amounts when, data transfer mistake Cheng Keneng needs more data block.And the increase of data number of blocks can cause the increase of valid data transmission time, reduction transmission Efficiency, therefore, in embodiments of the present invention, before sending first data transmission request to server, can also include：

Whether the frequency sum that judging first object frequency group includes is less than Second Threshold；

If so, then resurveying the voice signal sent in the environment that terminal is presently in, the voice signal is parsed, until It is determined that the frequency quantity that the corresponding first object frequency group of the environment being presently in includes, more than Second Threshold.

Wherein, Second Threshold, can be configured as needed.

Such as, Second Threshold, can be determined according to data volume to be sent.Specifically, due to data volume to be sent compared with When many, if being modulated using less frequency to sent data, the speed sent during transmission data may be caused slower, It therefore, it can to pre-set the corresponding relation of data volume to be sent and Second Threshold, such as, data volume to be sent is worked as in setting When more, Second Threshold is larger value, when data volume to be sent is less, and Second Threshold is less value.So as to basis The data volume to be sent and corresponding relation pre-set, determines Second Threshold.

Or, Second Threshold can also be according to sending in terminal, it is necessary to carry out the application of acoustic communication or process is set Put.Specifically, the mark and the corresponding relation of Second Threshold of application or process can be pre-set, so that it is determined that sending terminal In when starting certain default application or process, using corresponding relation, determine Second Threshold.For example, A applications only need to transmit user A small amount of character such as name and password, then Second Threshold, could be arranged to less numerical value, and such as 2；B application need transmission picture or The information of the big data quantities such as file, then Second Threshold, could be arranged to larger value, and such as 8.Then determine to send in terminal to start When certain applies A, you can according to the mark of application, it is 2 to determine Second Threshold.

Specifically, if the frequency sum that first object frequency group includes is more than Second Threshold, sending terminal can be by First data transmission request is sent to server, if the frequency sum that first object frequency group includes is not more than Second Threshold, Then sending terminal needs to resurvey and parse the voice signal sent in the environment that terminal is presently in, until determining current institute The frequency quantity that the corresponding first object frequency group of environment at place includes, after Second Threshold, then by first data transmission Request is sent to server, so that server carries out subsequent operation.

Sound wave communication method provided in an embodiment of the present invention, it is determined that sending the environment corresponding first that terminal is presently in After audio frequency characteristics and first object frequency group, first data transmission request is sent to server, then the reception server is issued Data transfer enabled instruction, recycles first object frequency group to be modulated to sent data, generates acoustic signals, finally Send acoustic signals.By according to the environment that terminal is presently in is sent, the less low noise frequency of acoustic jamming being determined, to treat Send data to be modulated, and the acoustic signals of generation are sent to receiving terminal, realize transmission terminal and exist with receiving terminal Shaken hands before carrying out acoustic communication, to determine currently available optimal frequency group, reduce the interference noise in acoustic communication, Improve the quality of acoustic communication.

By above-mentioned analysis, acoustic jamming can be determined according to the environment that terminal and receiving terminal are presently in is sent The acoustic signals of generation to be modulated to data to be sent, and are sent to receiving terminal, so by less low noise frequency And, in practice, it is understood that there may be two or more transmission terminals in same environment are needed to receiving terminal The situation of data is sent, with reference to Fig. 2, sound wave communication method provided in an embodiment of the present invention is further described.

Fig. 2 is a kind of schematic flow sheet of sound wave communication method according to an exemplary embodiment, this method application In transmission terminal.

As shown in Fig. 2 the sound wave communication method, comprises the following steps：

Step 201, default application is started it is determined that sending in terminal.

Wherein, default application, can refer to can carry out any application of acoustic communication.

Step 202, according to default application, Second Threshold is determined.

Specifically, because the data transmitted when different applications is using acoustic communication may be different, so that the frequency needed Quantity may be also different, therefore, in the embodiment of the present invention, can pre-set different applications and the mapping of Second Threshold is closed System, so that it is determined that after application startup, you can according to the mark of the application of startup, determine corresponding Second Threshold.

Step 203, with default sampling length, collection sends the voice signal in the environment that terminal is presently in.

Step 204, parse, determine each in voice signal to sending the voice signal in the environment that terminal is presently in The corresponding bottom of frequency is made an uproar, and determines corresponding first audio frequency characteristics of current environment.

Step 205, when the bottom of any one frequency in voice signal is made an uproar less than first threshold, bottom is made an uproar less than first threshold Frequency, add first object frequency group.

Wherein, bottom is made an uproar to refer to and sent in the environment that terminal is presently in, the overall noise in addition to useful signal.

First threshold, for characterizing the voice signal in the environment residing for transmission terminal, is produced smaller dry to acoustic communication Maximum noise value when disturbing.

Specifically, the voice signal sent in the environment that terminal is presently in first can be subjected to Fourier transformation, it is determined that The power spectral value p (i) of voice signal, wherein, i is frequency sequence number value, then determines each frequency in voice signal according to frequency spectrum Bottom make an uproar n (i).Wherein it is possible to which using various ways, the bottom for determining each frequency according to frequency spectrum is made an uproar.

Such as, according to n (i)=a* (i)+(1-a) * p (i), determine that the bottom of i-th of frequency is made an uproar value.

Wherein, a is proportionality constant, and environment that can be rule of thumb or residing for first terminal determines that the present embodiment is to this It is not construed as limiting.

Further it will be understood that it is a curve that the bottom of a frequency, which is made an uproar, even if when the virtual value of curve is less than necessarily During value, its fluctuation having still may be larger, now can still be easier to be disturbed, therefore, it is also desirable to judge that it fluctuates model Whether safe enclose.Therefore, in embodiments of the present invention, the difference value that can also be made an uproar the bottom of by, judges the corresponding noise of each frequency Size, so that it is determined that the frequency in first object frequency group.That is, before step 205, it can also include：Determine that bottom is made an uproar to be less than The frequency of first threshold, corresponding bottom is made an uproar difference value.

Specifically, being made an uproar and difference value that bottom is made an uproar, being determined in first object frequency group the bottom of according to by a variety of methods Frequency.

Method one

Bottom is made an uproar and is less than the frequency of the 3rd threshold value less than first threshold and bottom difference value of making an uproar, first object frequency group is added.

Method two

Determine that the bottom of each frequency in voice signal is made an uproar the factor, its midsole bottom that the factor is each frequency of making an uproar is made an uproar and bottom is made an uproar difference value Product；

By bottom make an uproar the factor be less than the 4th threshold value frequency, add first object frequency group.

When implementing, bottom can be made an uproar and be less than the frequency of the 3rd threshold value less than first threshold and bottom difference value of making an uproar, added First object frequency group, or, by bottom make an uproar with bottom make an uproar difference value product be less than the 4th threshold value frequency, add first object frequency Point group.Or, other methods can also be used, first object frequency group is determined, is not restricted herein.

Step 206, whether the frequency sum that judging first object frequency group includes is more than Second Threshold.If so, performing Step 207, otherwise, return and perform step 203.

Step 207, first data transmission request is sent to server, it is special that first data transmission request includes the first audio Levy and first object frequency group.

Step 208, the data transfer enabled instruction that the reception server is issued, wherein, in data transfer enabled instruction, including Second target frequency group.

Wherein, first object frequency group includes the second target frequency group.

Step 209, it is modulated using the second target frequency group to sent data, generates acoustic signals.

Step 210, acoustic signals are sent.

Wherein, step 201-203, step 206-207, step 209-210's implements process and principle, is referred to The detailed description of above-described embodiment one, here is omitted.

It is understood that in practice, it is understood that there may be two or more transmissions in same environment Terminal needs to send the situation of data to receiving terminal, i.e. two send the terminal currently residing corresponding audio of environment of difference Feature and target frequency, audio frequency characteristics and target frequency matching corresponding with the environment that receiving terminal is presently in.Then server Or each frequency in the target frequency group of matching can be divided into two parts by receiving terminal, it is respectively allocated to two and sends eventually End, and data transfer enabled instruction is sent respectively from server to two transmission terminals and receiving terminal, so that two transmissions Terminal is utilized respectively corresponding target frequency group in instruction and entered to sent data after data transfer enabled instruction is received Row modulation, generates acoustic signals, and acoustic signals are sent into receiving terminal by equipment such as loudspeakers.

For example, as shown in Figure 2 A, it is assumed that send terminal A, send the environment pair that terminal B and receiving terminal are currently located The audio frequency characteristics matching answered, corresponding target frequency group includes frequency 1, frequency 2, frequency 3, frequency 4, then receiving terminal is determined Two send after terminal target frequency matching corresponding with the environment residing for receiving terminal currently difference, can be by frequency 1, frequency 2 distribute to transmission terminal A, and frequency 3 and frequency 4 are distributed into transmission terminal B.Terminal A is then sent, terminal B is sent and receives eventually Termination is received after the data transfer enabled instruction of server transmission, sends terminal A i.e. using frequency 1 and frequency 2 to be sent Data be modulated, generate acoustic signals, and acoustic signals be sent to receiving terminal.Meanwhile, sending terminal B can utilize Frequency 3 and frequency 4 are modulated to sent data, generate acoustic signals, and acoustic signals are sent into receiving terminal.

Or, terminal currently the difference residing corresponding audio frequency characteristics of environment and target frequency are sent at two, with reception When the corresponding audio frequency characteristics of environment and target the frequency matching that terminal is presently in, server or receiving terminal can be set respectively Put two and send the time that terminal sends data, and data are sent respectively to two transmission terminals and receiving terminal from server and pass Defeated enabled instruction, so that two send terminal and receive after data transfer enabled instruction, can be treated according to target frequency group The data of transmission are modulated, and generate acoustic signals, and do not sending acoustic signals to receiving terminal in the same time.

That is, in data transfer enabled instruction, it can also include：Time delay.Accordingly, step 210 can specifically include： After time delay terminates, acoustic signals are sent.

As an example it is assumed that sending terminal A, sending the corresponding audio spy of environment that terminal B and receiving terminal are currently located Matching is levied, corresponding target frequency group includes frequency 1, frequency 2, frequency 3, frequency 4, then server or receiving terminal determine two It is individual to send after terminal target frequency matching corresponding with the environment residing for receiving terminal currently difference, transmission terminal A can be set to exist Receive after data transfer enabled instruction, data to be sent be just sent to receiving terminal, send terminal B after 1s, restart by Data to be sent are sent to receiving terminal.Then send the number that terminal A, transmission terminal B and receiving terminal receive server transmission After being instructed according to transmission start, send terminal A and adjusted using frequency 1, frequency 2, frequency 3, frequency 4 to sent data System, generates acoustic signals, and acoustic signals are sent into receiving terminal.Send terminal B and frequency 1, frequency 2, frequency can also be used 3rd, frequency 4 is modulated to sent data, generates acoustic signals, and after 1s, acoustic signals are sent to reception by startup Terminal.

Further, in embodiments of the present invention, it can also include in first data transmission request：Send the mark of terminal Know, so that server or receiving terminal can be according to the marks for sending terminal, it is determined that sending the corresponding target frequency group of terminal Or time delay, it is modulated so as to send terminal using corresponding target frequency group to sent data, and by generation Acoustic signals are sent to receiving terminal, or after time delay terminates, acoustic signals are sent to receiving terminal.

In a kind of preferably way of realization of the application, due to the voice signal of different frequent points, in acoustic communication by dry The probability disturbed is different with degree, therefore, in the embodiment of the present application, can also by analyzing history acoustic communication data, It is determined that preferably acoustic communication frequency pond, so as to when the voice signal in current environment is parsed, only judge frequency pond In each frequency it is whether available, so as to reduce the processing load for sending terminal.

Wherein, preset frequency pond can be shifted to an earlier date by sending in terminal, or, can also be to server real-time query frequency pond； Or, this can also not limited according to current environment feature real-time update, the present embodiment.

And the frequency in frequency pond, can also be adjusted according to different environment.For example, it is assumed that sending terminal generally in horse Road, bus, market, dining room, have in the environment of noisy loud background music etc. and to carry out acoustic communication with receiving terminal, then It can predefine in above-mentioned environment, data to be sent are modulated with which frequency, the acoustic signals of generation can be made It is disturbed degree minimum, communication quality is best, so as to regard these frequencies as each frequency in frequency pond.Further according to frequency pond In the bottom of each frequency make an uproar, determine each frequency, if first object frequency group can be added.

Sound wave communication method provided in an embodiment of the present invention, default application is being started it is determined that sending in terminal, and really Surely after transmission terminal is presently in corresponding first audio frequency characteristics of environment and first object frequency group, however, it is determined that first object frequency The frequency sum that point includes is more than Second Threshold, then sends first data transmission request to server, then the reception server The data transfer enabled instruction issued, recycles the second target frequency group in data transfer enabled instruction to sent data It is modulated, generates acoustic signals, finally send acoustic signals.The ring being presently in by using transmission terminal and receiving terminal Border, determines the less low noise frequency of acoustic jamming, to be modulated to data to be sent, and the acoustic signals of generation is sent to Receiving terminal, realizes and is shaken hands between transmission terminal and receiving terminal before acoustic communication, to determine currently available optimal frequency Point group, reduces the interference noise in acoustic communication, improves the quality of acoustic communication.

Below by taking server side as an example, sound wave communication method provided in an embodiment of the present invention is described in detail.
