2 groups of communication pins of mouth 1 are corresponding with 2 groups of communication pins of external equipment, in order to which external equipment passes through its first group of communication
Pin receives and saves file, is handled by its second group of communication pin audio data.
The communication channel is in the communication pin and in running order the of the second interface 2 of working condition
Electrical connection is established between the communication pin of one interface 1, and data transmission, including signal transmission are carried out by the connection.For example, after
Continuous above example, the communication pin 21 of the USB3.0 interface of in running order second interface 2 with it is in running order
Electrical connection is established between first group of communication pin 11 of first interface 1；The audio interface of in running order second interface 2
It establishes and is electrically connected between communication pin 22 and second group of communication pin 12 of in running order first interface 1.
The connection type of the first interface 1 includes: positive connection type and Opposite direction connection mode.For example, described first
Interface 1 is USB type-c interface.
The control module 3 includes processor 31 and switch unit 32.
The processor 31, for obtaining the transmission type information of in running order second interface 2, and according to described
Transmission type information sends control information to the switch unit 32.For example, processor 31 is specifically microprocessor
(Microcontroller Unit, abbreviation MCU).
The switch unit 32, for according to the control information of the processor 31 the first interface 1 communication pipe
Communication channel is established between foot and the communication pin of in running order second interface 2.For example, switch unit 32 is first to connect
Logical device, each logic is arranged in the crosspoint of " well " font net in " well " the font net formed between mouth 1 and second interface 2
The output of device is controlled by the control information that MCU is exported.
The control information, includes at least: the transmission type information of in running order second interface 2 and be in work
Make the connection type information of the first interface 1 of state.
For example, continuing the example above, the first interface 1 is USB type-c interface, and second interface 2 is that USB3.0 connects
Mouth and audio interface.Shown in Figure 2, when USB type-c interface and in running order USB3.0 interface, MCU is obtained
The transmission type information of USB3.0 interface and the connection type information of USB type-c interface, and believed according to the transport-type
Breath and connection type information are sent to the switch unit 32 controls information, and switch unit 32 is made to establish the communication of USB3.0 interface
Communication channel between pin 21 and the first group of communication pin 11 and/or second group of communication pin 12 of USB type-c interface.
For example, continuing the example above, shown in Figure 3, the USB type-c interface of the present embodiment circuit is forward direction
Connection type, the communication pin of the USB type-c interface of external equipment are preset the type of transmission data, it is assumed that external
First group of communication pin of the USB type-c interface of equipment is predetermined the data for receiving USB3.0 interface, second group of communication pin
It is predetermined the data for receiving audio interface.The USB type-c interface of the present embodiment circuit is positive connection type, therefore, this reality
Apply first group of communication pin 11 of the USB type-c interface of circuit and the USB with external equipment of second group of communication pin 12
The communication pin of type-c interface is corresponding.When USB type-c interface, USB3.0 interface and the audio interface of embodiment circuit
When in running order, the transmission type information and USB type-c interface of MCU acquisition USB3.0 interface and audio interface
Positive connection type information, and sent according to the transmission type information and positive connection type information to the switch unit 32
Information is controlled, switch unit 32 is made to establish first group of communication pipe of the communication pin 21 and USB type-c interface of USB3.0 interface
Second group of communication pin 12 of the communication pin 22 and USB type-c interface of communication channel and audio interface between foot 11
Between communication channel.
For example, continuing the example above, shown in Figure 3, the USB type-c interface of the present embodiment circuit is reversed
Connection type, therefore, the USB of first group of communication pin 11 and external equipment of the USB type-c interface of the present embodiment circuit
Second group of communication pin of type-c interface is corresponding, the USB type-c interface of second group of communication pin 12 and external equipment
First group of communication pin is corresponding.When USB type-c interface, USB3.0 interface and the audio interface of embodiment circuit are in work
When making state, MCU obtains the transmission type information of USB3.0 interface and audio interface and reversely connecting for USB type-c interface
Mode information is connect, and control letter is sent to the switch unit 32 according to the transmission type information and Opposite direction connection mode information
Breath, make switch unit 32 establish USB3.0 interface communication pin 21 and USB type-c interface second group of communication pin 12 it
Between communication channel and audio interface communication pin 22 and first group of communication pin 11 of USB type-c interface between
Communication channel.
