Embodiment
We will by reference to the accompanying drawings below, is described in detail optimum implementation of the present invention.First it is to be noted, the implication of the term used in the present invention, words and claim only can not be only limitted to its literal and common implication and go to understand, the implication also comprised and then conform to technology of the present invention and concept, this is because we are as inventor, suitably to provide the definition of term, to carry out the most appropriate description to our invention.Therefore, the configuration provided in this explanation and accompanying drawing, just first-selected embodiment of the present invention, instead of all technical characteristics of the present invention will be enumerated.We will recognize, also have various equivalent scheme or the modification that can replace our scheme.
Basic thought of the present invention is: tone frequency channel wire sequence corresponding with this model for the model of various terminal stored with the form of type information and tone frequency channel wire sequence information in advance, so, after external device is connected to the audio interface of terminal, terminal obtains built-in type information in the terminal, just can extract corresponding tone frequency channel wire sequence information according to above-mentioned corresponding relation; Then, this tone frequency channel wire sequence information is sent to external device by terminal, so, external device just can resolve obtain described terminal tone frequency channel wire sequence.
Below in conjunction with accompanying drawing, describe mobile terminal of the present invention in detail by specific embodiment and trigger the specific implementation that external device obtains the method for tone frequency channel wire sequence.
Shown in Fig. 1 is the basic flow sheet of the embodiment of the method one obtaining tone frequency channel wire sequence in the present invention.This embodiment comprises the steps:
After step 101, described terminal detect that external device is connected to described terminal by audio interface, obtain the type information being built in described terminal.
Type information can be the specific product model of this terminal, also can be the model of product line described in this terminal.Terminal production firm sometimes can not by the terminal built-in for this terminal specific product model, but by the terminal built-in for the model of product line belonging to this terminal.The tone frequency channel wire sequence adopted under normal circumstances due to a serial end product is identical, and the model therefore by obtaining this series also can realize the technical scheme of the present embodiment.
Step 102, described terminal, according to described type information, by the corresponding relation of type information and tone frequency channel wire sequence information, obtain the tone frequency channel wire sequence information corresponding with described type information.
It should be noted that, the corresponding relation of type information and tone frequency channel wire sequence information needs preset in advance.This corresponding relation can be preset in described terminal, also can be preset in network side server.Because the update of current end product is very frequent, this corresponding relation needs to constantly update with the corresponding relation comprising new terminal product.And be preset at that corresponding relation in network side server upgrades than in terminal more timely, so this step 102 preferably the direct corresponding relation from being preset at network side server obtain tone frequency channel wire sequence information.If but terminal all needs with network side server mutual during each acquisition tone frequency channel wire sequence, mutual number of times can too much, and the efficiency of server response terminal request will reduce.In order to reduce the interaction times of terminal and network side server as far as possible, ensure the tone frequency channel wire sequence getting various end product, the present embodiment can adopt execution mode completing steps 102 as shown in Figure 2, comprises the steps: simultaneously
Described type information whether is comprised in first corresponding relation of step 201, described terminal judges type information and tone frequency channel wire sequence information; Described first corresponding relation is preset in described terminal; If so, step 202 is entered; If not, step 203 is entered.
Step 202, described terminal, by described first corresponding relation, extract the tone frequency channel wire sequence information that described type information is corresponding.
Step 203, described terminal, by the second corresponding relation of type information and tone frequency channel wire sequence information, extract the tone frequency channel wire sequence that described type information is corresponding; Described second corresponding relation is preset in network side server.
Certainly, in the present embodiment, user at any time by the first corresponding relation preset in network side server more new terminal, so can reduce the number of times of terminal and server interaction further.
Execution of step 102, enters step 103.
Described tone frequency channel wire sequence information is sent to described external device by step 103, described terminal, so that described external device is according to described tone frequency channel wire sequence information, resolves the tone frequency channel wire sequence obtaining described terminal.
It should be noted that, undertaken alternately in the present embodiment between terminal and external device by audio interface, is utilize existing terminal all to have the function that can be realized audio plays and recording audio by audio interface.Carry out in the process of record/playback in terminal, audio plays is actually terminal and sends analog signal by the L channel line of audio interface and/or the external tone playing equipment of R channel alignment, and recording audio is actually terminal and receives by the microphone lines of audio interface the analog signal that external sound pick-up outfit sends.Therefore, in the present embodiment, the information interaction of terminal and external device is specially: terminal outwards installs preparation by the left and/or right sound channel of audio interface and send analog signal, and external device sends analog signal by the microphone lines of audio interface to terminal.
In order to realize the process of information and data interaction, data mutual between terminal and external device need the mode adopting analog signal modulation, as FSK mode, by the waveform modelling signal of certain frequency or certain amplitude, represent certain data.Like this, when interaction data, external device or terminal just need to resolve to the received signal, obtain the data of its representative.Based on the function of existing terminal recording playback audio frequency, the present embodiment is when resolution data, the analog signal that terminal is received from microphone lines according to the tone frequency channel wire ordered pair of self is resolved, and external device is then resolved according to the analog signal be received from left/right sound channel line when front ordered pair of self.
Prior art sound intermediate frequency line sequence only has two kinds, and only has microphone lines different with the position of ground wire in these two kinds of tone frequency channel wire sequences, and the position of left and right acoustic channels line is all identical.Based on this reason, when external device sends information or data to terminal, if the line sequence of external device is different from terminal audio frequency line sequence, then during terminal parses data, because when the signal place circuit for resolving and external device send data, circuit used is different, the data that therefore terminal parses obtains will be no longer the data that external device sends; And terminal is when outwards installing preparation carry information or data, no matter whether both line sequences are identical, and the circuit that the circuit that terminal sends signal and external device are used for analytic signal is all identical, and therefore external device can both be resolved to the data of terminal transmission.As can be seen here, when the line sequence of external device is different with the tone frequency channel wire sequence of terminal, external device correctly can resolve the information obtaining terminal and send, and terminal correctly can not resolve the information obtaining external device and send.
For these reasons, in this step 103, no matter whether the line sequence of current external device matches with the tone frequency channel wire sequence of terminal, external device normally can resolve the audio-frequency information that terminal sends, and obtaining the data about tone frequency channel wire sequence of terminal transmission, external device is according to the tone frequency channel wire sequence of this data determination terminal thus.Particularly, terminal can be arranged with external device, the tone frequency channel wire sequence of terminal is determined according to the content of data, such as: when the tone frequency channel wire sequence that terminal determines oneself is First Line sequence, then send in tone frequency channel wire sequence information and comprise data " 11111111 ", external device receives and resolves when obtaining data " 11111111 ", then the tone frequency channel wire sequence of terminal is defined as First Line sequence; And when the tone frequency channel wire sequence that terminal determines oneself is the second line sequence, then sends in tone frequency channel wire sequence information and comprise data " 00000000 ", external device receives and resolves and obtains data " 00000000 ", then the tone frequency channel wire sequence of terminal is defined as the second line sequence.
In addition, the present embodiment, after step 103, can also comprise: described external device utilizes the described tone frequency channel wire sequence obtained, and carries out data interaction with described terminal.So, external device can utilize terminal to realize the function of self by audio interface.
In addition, in the present embodiment, described terminal can be the terminal that desktop computer etc. is fixed, and also can be the mobile terminals such as mobile phone, pad, notebook computer.
By the technical scheme of the present embodiment, by obtaining the type information of terminal, the tone frequency channel wire sequence information of terminal can be obtained further according to the corresponding relation of type information and tone frequency channel wire sequence information, thus for different terminals, external device correctly can both obtain the tone frequency channel wire sequence of terminal, thus can carry out normal data interaction with terminal.
When terminal obtains audio-frequency information according to type information, if do not comprise model in corresponding relation preset in terminal and terminal now can not be connected with network side server, then terminal just temporarily can not obtain audio-frequency information.In order to obtain the tone frequency channel wire sequence of terminal as early as possible, present invention also offers a kind of embodiment of the method two obtaining tone frequency channel wire sequence, as shown in Figure 3, comprising the steps:
After step 301, described terminal detect that external device is connected to described terminal by audio interface, obtain the type information being built in described terminal.
Step 302, described terminal, according to described type information, by the corresponding relation of type information and tone frequency channel wire sequence information, obtain the tone frequency channel wire sequence information corresponding with described type information.
Whether step 303, described terminal judges obtain tone frequency channel wire sequence information successful; If so, step 304 is entered; If not, step 305 is entered.
As terminal temporarily can not obtain tone frequency channel wire sequence information for above-mentioned reasons, then terminal check obtains unsuccessful.In this case, enter step 305, to realize following scheme: can external device sends line order sequenced data according to First Line sequence to terminal, then resolve according to the tone frequency channel wire sequence of self the tone frequency channel wire sequence that the judged result obtaining this line order sequenced data obtains terminal according to terminal.
Described tone frequency channel wire sequence information is sent to described external device by step 304, described terminal, so that described external device is according to described tone frequency channel wire sequence information, resolves the tone frequency channel wire sequence obtaining described terminal.
Step 305, described terminal receive the line order sequenced data that described external device sends according to First Line sequence.
Terminal can adopt the mode starting endless track sound recording to carry out wait-receiving mode external device and send and next data.In addition, First Line sequence can be any one in two kinds of tone frequency channel wire sequences, preferably using the default line sequence of external device as First Line sequence.
Step 306, described terminal resolve described line order sequenced data according to the tone frequency channel wire sequence of described terminal, obtain resolution data.
Described terminal parses line order sequenced data is resolved according to the tone frequency channel wire sequence of terminal self.According to the explanation to step 103, terminal receives data by audio interface, receives data indeed through the microphone lines on interface, so, when terminal resolves line order sequenced data according to self tone frequency channel wire sequence, be the data be resolved to according to the simulation that microphone lines receives.
Whether resolution data described in step 307, described terminal judges is identical with described line order sequenced data; If so, step 308 is entered; If not, step 309 is entered.
Because in two kinds of tone frequency channel wire sequences, the position of microphone lines is not identical, terminal resolves according to self tone frequency channel wire sequence the resolution data obtained might not be identical with line order sequenced data.If it is identical with the tone frequency channel wire sequence of terminal that external device sends the First Line sequence adopted, the data that terminal parses obtains are just identical with line order sequenced data; If line sequence is not identical with tone frequency channel wire sequence, then the data of terminal parses are just not identical with line order sequenced data.Thus, by judging that whether resolution data and line order sequenced data be identical, terminal can confirm that whether First Line sequence is identical with tone frequency channel wire sequence.
Step 308, described terminal send line sequence confirmation to described external device, so that described external device is according to described line sequence confirmation, described First Line sequence are retrieved as the tone frequency channel wire sequence of described terminal.
Based on the explanation to step 307, resolution data is identical with line order sequenced data, then First Line sequence is identical with terminal audio frequency line sequence, and as in the case, terminal sends line sequence confirmation with the tone frequency channel wire sequence making external device First Line sequence is retrieved as terminal.
Step 309, described terminal send line sequence adjustment information to described external device, so that described external device is according to described line sequence adjustment information, the second line sequence are retrieved as the tone frequency channel wire sequence of described terminal.
Based on the explanation to step 307, resolution data is not identical with line order sequenced data, then First Line sequence is not identical with terminal audio frequency line sequence, and as in the case, terminal sends line sequence adjustment information, to make external device, the second line sequence is retrieved as the tone frequency channel wire sequence of terminal.
It should be noted that, concerning step 309, although the current First Line sequence of external device is different from the tone frequency channel wire sequence of terminal, in First Line sequence, the position of left/right sound channel is identical with terminal audio frequency line sequence.Like this, according to the explanation to step 103, when terminal sends line sequence adjustment information to external device, the data that the analog signal in external device parsing left/right sound channel obtains are identical with the data that terminal sends, therefore, external device correctly can obtain the tone frequency channel wire sequence of terminal.
In addition, the present embodiment, after step 304 or step 309, can also comprise: described external device utilizes the described tone frequency channel wire sequence obtained, and carries out data interaction with described terminal.So, external device can utilize terminal to realize the function of self by audio interface.
In addition, in the present embodiment, described terminal can be the terminal that desktop computer etc. is fixed, and also can be the mobile terminals such as mobile phone, pad, notebook computer.
By the technical scheme of the present embodiment, when terminal temporarily can not obtain tone frequency channel wire sequence information according to type information, external device sends First Line order sequenced data according to First Line sequence to terminal, the tone frequency channel wire sequence that the judged result obtaining First Line order sequenced data obtains terminal can be resolved again according to terminal, thus when terminal abnormal can not obtain tone frequency channel wire sequence information according to corresponding relation, external device still correctly can obtain the tone frequency channel wire sequence of terminal, thus can carry out normal data interaction with terminal.
