Moreover, the port 12 can be electrically connected to the system single chip 22 via the serial communication bus 21 or other input/output lines (not shown).

With continued reference to FIG. 1, the electronic device 20 can interact with the peripheral device 30, for example, the peripheral device 30 is used as an input/output device to directly receive input data from the peripheral device 30, The instruction; or outputting data, instructions to the peripheral device 30; or starting, executing, stopping, and closing the software corresponding to the peripheral device 30. A portion of the peripheral device 30 can be contacted and secured in the port 12 and form a signal path for the peripheral device 30 and the port 12 after attachment. For example, the peripheral device 30 is an earphone with an audio plug, and the connection port 12 is an I/O port jack, such as an audio jack, which can be connected with the audio plug of the earphone, and after docking The port 12 and peripheral device 30 establish a signal path.
