Specific embodiment
Below in conjunction with attached drawing, an exemplary embodiment of the present invention will be described, including the various of the embodiment of the present invention
Details should think them only exemplary to help understanding.Therefore, those of ordinary skill in the art should recognize
It arrives, it can be with various changes and modifications are made to the embodiments described herein, without departing from scope and spirit of the present invention.Together
Sample, for clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.
In embodiments of the present invention, use multiple access technology to the coding digital information of different content for different channels address
Broadcasting sound signal, different classes of user receive the broadcasting sound signal of different channels address respectively to obtain different letters
Breath.For example, first kind user's bandwidth allocation is 16-17kHz by the way of frequency division multiple access, second class user's bandwidth allocation is
17-18kHz, third class user's bandwidth allocation are 18-19kHz；It will be directed to the above-mentioned first kind, the second class, third class user respectively
Information coding be modulated to bandwidth 16-17kHz, 17-18kHz, 18-19kHz signal then and meanwhile send.Above-mentioned three classes user
After opening the application program on the intelligent terminals such as mobile phone and login, application program identifies class of subscriber, and controls mobile phone
Microphone obtain air Acoustic channel in voice signal, by user class of subscriber to the signal in respective bandwidth carry out demodulation translate
Code just obtains the information for the user.It elaborates below to the technical solution of the embodiment of the present invention.
Fig. 1 is the schematic diagram of the basic step of the method according to an embodiment of the present invention for propagating information.This method is by information
Transmitting terminal executes, and mainly includes the following steps, namely the S11 to step S13.
Step S11: according to the multiple access technology used, a pair between multiple channel address and multiple class of subscribers is recorded
It should be related to.Here channel address is used to distinguish each channel, and for example, by using frequency division multiple access technology, channel address is each band
It is wide；Using Code Division Multiple Access, channel address is each spreading code.Still by taking above example as an example, the content of record is are as follows:
First kind user: 16-17kHz
Second class user: 17-18kHz
Third class user: 18-19kHz
Step S12: multiple access technology is used, by channel corresponding to target user's classification of the multiclass information according to various information
Address carries out coded modulation respectively and forms multiple groups acoustic coding signal.In conjunction with upper example, and such as type I information, the second class are believed
Breath, third category information target user be above-mentioned first kind user, the second class user, third class user respectively, then by first
Category information, the second category information, third category information using frequency division multiple access technology for encoding be modulated to respectively 16-17kHz, 17-18kHz,
Three groups of acoustic coding signals within the scope of 18-19kHz.
Step S13: multiple groups acoustic coding signal obtained in step S12 is sent simultaneously via air Acoustic channel.
Such as in market, the music that played in market and the multiple groups acoustic coding signal can be subjected to audio mixing and then played.
For a user, the equipment such as mobile phone can be used to receive above-mentioned acoustic coding signal and then obtain number therein
Information.For this purpose, the application program in mobile phone process can execute as shown in Figure 2.Fig. 2 is acquisition information according to an embodiment of the present invention
Method basic step schematic diagram.

The content of example, record may is that
First kind user name: 16-17kHz
Second class user name: 17-18kHz
Third class user name: 18-19kHz
Step S22: it receives user name and logs in.It usually requires to authenticate when login, that is, user's input password or short message is required to test
Demonstrate,prove the authentication informations such as code.Described below is the step of the authentication is passed later, does not export prompt information if authentication does not pass through, it is desirable that
User re-enters authentication information.
Step S23: the corresponding channel address of user name logged in is determined according to the corresponding relationship recorded in step S21.This
In step first according to user name determine it belonging to user name classification, which as currently steps on
The corresponding channel address of the user name of record.
Step S24: the channel address determined from step S23 receives air Acoustic channel and uploads the information sent, by the letter
Breath carries out demodulation coding and obtains digital information.Such as the channel address determined is 17-18kHz, then by the band of demodulated signal
Width is set as 17-18kHz, and acoustical signal is converted to digital information by the audio decoder chip in calling mobile phone.The digital information can
To be text or image etc., such as the network address or photo of commodity.
