Of course, the connection between the main device 70 and the third connecting device 40 of the electronic device may also be realized through a data line, as shown in fig. 2b, the connection manner between the main device 70 and the third connecting device 40 is not limited to the above plug connection manner listed in this application, and the connection between the main device 70 and the third connecting device may also be realized through a wireless manner (such as WIFI, bluetooth, radio frequency, etc.), the connection manner may be flexibly selected according to actual requirements, and the detailed description is not given in this application.
It should be noted that in the embodiment of the present application, the third connecting device 40 can form a communication path with the first connecting device 20 and/or the second connecting device 20, so that the main device 70 can be connected to the display device 10 and/or the input device 60, and the specific communication path can be determined according to the actual application requirement.
Therefore, in practical applications, in the case that the main device 70 needs to multiplex the display device 10 of the electronic device to output the information in the main device 70, the main device 70 may be connected to the third connecting device 40 of the electronic device, and the third connecting device 40 and the first connecting device 20 are controlled to form a communication path therebetween, so that the information to be output (such as video signals, text information, and the like) output by the main device 70 can be transmitted to the display device 10 of the electronic device for displaying through the communication path.
When the main device 70 needs to multiplex the input device 60 of the electronic device, that is, under a scenario that the input device 70 controls the main device 70, after the main device 70 is connected to the third connecting apparatus 40 of the electronic device, a communication path may be formed between the third connecting apparatus 40 and the second connecting apparatus 30, so that an input instruction generated by a user operating the input device may be sent to the main device 70 through the communication path, so that the main device may execute a preset operation in response to the input instruction.
Furthermore, when the main device 70 multiplexes the display apparatus 10 and the input device 60 of the electronic device, i.e. the content output by the main device 70 needs to be projected to the display apparatus 10 of the electronic device for output, and in the scene of using the input device 60 to realize the operation of the main device 70, after the main device 70 is connected to the third connecting device 40 of the electronic device, the third connecting means 40 can be controlled to form a communication path with the first connecting means 20 and the second connecting means 30, respectively, and in conjunction with the above description, the information that the main device 70 needs to display can be sent to the display apparatus 10 through the communication path between the third connecting means 40 and the first connecting means 20, the input command generated by the input device 60 can be sent to the main device 70 through the communication path between the third connecting apparatus 40 and the second connecting apparatus 30, so that the main device can respond to the input command to meet the operation requirement of the user on the main device 70.
It should be noted that, the present application is not limited to the manner how to implement the communication control between the third connecting device 40 and the first connecting device 20 and the second connecting device 30, and reference may be made to, but not limited to, the description of the corresponding parts of the following embodiments.
The processing device 50 may be configured to, in a first operating state of the electronic device, send the multimedia signal output by the main device 70 to the display device 10 for output, and send an input instruction output by the input device 60 to the main device 70, so that the first processor of the main device 70 executes a first preset operation in response to the input instruction; when the electronic equipment is in the second working state, the multimedia signal obtained by the electronic equipment is sent to the display device 10 for output, and a second preset operation is executed in response to an input instruction output by the input equipment 60;
in connection with the analysis of the above embodiment, in the first operating state of the electronic device, the third connecting device 40 forms a communication path with the first connecting device 20 and the second connecting device 30; in the second operating state of the electronic device, no communication path is formed between the third connecting device 40 and the first connecting device 20 or the second connecting device 30.
It can be seen that, in the first operating state of the electronic device, the main device 70 needs to multiplex the display apparatus 10 and the input device 60 of the electronic device, and the present embodiment may control the first connecting apparatus 20, the second connecting apparatus 30 and the third connecting apparatus 40 to form corresponding communication paths in the manner described above, and the specific control process is not described in detail, in this case, as shown in fig. 2b and 2c, the content output by the display of the main device 70 is consistent with the content output by the display apparatus 10 of the electronic device, and especially for the main device 70 with a small screen, the display apparatus 10 with a large screen of the electronic device may be used to display the content that the main device 70 needs to display.
In the second working state of the electronic device, it may mean that the main device 70 does not need to multiplex the electronic device, and the electronic device may work in a conventional manner, that is, the display device 10 may output information that the electronic device needs to output, the user operates the input device 60, and the second processor (such as a CPU, etc.) of the processing device 50 of the electronic device responds to the input instruction, so as to implement the required application operation. In this case, the main device 70 cannot reuse the display apparatus 10 and the input device 60 of the electronic device regardless of whether the main device 70 is connected to the third connecting apparatus 40, as shown in fig. 2a, even if the main device 70 is still placed in the slot of the electronic device, the display screen content thereof cannot be projected onto the display screen of the electronic device.
In this case, of course, the main device 70 may still multiplex other devices of the electronic device, such as an audio output device, or may not need to multiplex any device of the electronic device, and the present application does not describe in detail the specific application scenarios of the first state and the second state, and the control manner of the device of the electronic device itself in different application scenarios.
It should be noted that, for the working state that the electronic device can enter, the electronic device is not limited to the first working state and the second working state, and the electronic device can be controlled to be in other working states according to other application requirements, for example, the main device multiplexes an audio output device of the electronic device, plays an audio signal in a multimedia signal, and the like, and details of the embodiment of the present application are not described herein.
Moreover, even if the electronic device enters the first operating state or the second operating state, the control operation executed by the processing device is not limited to the content described above, and the content of the control operation that can be implemented by the first processor of the main device and/or the second processor of the electronic device may be determined according to the actual requirement and the communication path formed by the electronic device in the corresponding operating state, which is not described in detail herein.

And when the main device does not need to multiplex the display device and the input device of the electronic device, the electronic device is controlled to enter the second working state, at this time, the third connecting device and the first connecting device and the second connecting device do not form a communication path, so that the multimedia signal of the electronic device can be output by the display device, and the electronic device can respond to the input instruction output by the input device, thereby meeting the operation requirement of the user on the application of the electronic device.
