For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Data transmission method of the present invention, be applied to first terminal, and described first terminal has first interface, and described first interface has the first working method of transmission of audio signal and the second working method of transmission binary data signal.A concrete example can be: the 3.5mm earphone interface on mobile phone, can be used for transmitting voice signal, and also can be used for the transfer files data.
The flow chart that Fig. 1 is data transmission method of the present invention.As shown in Figure 1, described method can comprise:
Step 101: when described first interface is connected with the second interface of the second terminal, described first terminal is set to the first working method;
Concrete, described interface can be audio interface, for example the 3.5mm earphone interface.Described first interface can be connected by data wire disclosed by the invention with the second interface.Now, described first terminal is set to the first working method, can pass through first interface transfer files data, and can not carry out the action played sound.
Step 102: when the second terminal be connected with described first interface is audio frequency apparatus, described first terminal is set to the second working method.
Concrete, the second terminal can be the equipment such as earphone.Now, described first terminal is set to the second working method, can carry out the action such as play sound.
Data transmission method of the present invention, by utilizing the Interface realization transfer of data such as existing earphone interface on terminal, expanded the function of terminal interface of the prior art, can make transfer of data become more simple, and not be subject to the interference of other signal sources.
For ease of understanding, below the setting up procedure about the first working method and the second working method in method of the present invention is specifically described.
Fig. 2 is the flow chart that described first terminal of the present invention is set to the first working method.As shown in Figure 2, described first terminal is set to the first working method and can comprises:
