Interface can be for equipment such as the charger of terminal unit charging, such as, charger for mobile phone, notebook computers for connecting.
As it is shown in fig. 7, the first detection port in 3.5mm audio interface and the second detection port (" insert detection 1 " and
" insert detection 2 ") it is connected with port VCONN with the port CC in USB type C plug interface A respectively；3.5mm audio frequency connects
Part data-in port (MIC/AGND and AGND/MIC) in Kou and the port SBU1 in USB type C plug interface A
It is connected with port SBU2；Another part data-in port (" Right/ R channel " and port in 3.5mm audio interface
" Left/ L channel ") it is connected with port D+ with the port D-in USB type C plug interface A.In 3rd data-interface
Port VBUS in port VBUS and USB type C plug interface A is connected.In the figure 7, the port in the 3rd data-interface
ID and port GND ground connection.
Specifically, it is assumed that the first data-interface has been connected to terminal unit.When 3.5mm audio interface has audio output apparatus
During insertion, port " inserts detection 1 " and is connected with " inserting detection 2 ", and now, port " inserts detection 1 " and becomes high level, due to
Port CC with VCONN is connected with " inserting detection 1 ", and therefore, port CC Yu VCONN becomes high level.When terminal unit detects
After becoming high level to port CC Yu VCONN, determine that the second data-interface has audio output apparatus to access, now, the most permissible
By the data of port D-and D+ transfer audio files to audio output apparatus.If it should be noted that audio output apparatus
Mike is installed, i.e. by data-in port MIC/AGND and AGND/MIC in the second data-interface, user can be inputted
Audio file data transmit to terminal unit.If user is intended for terminal unit charging, it is also possible in the 3rd data
Interface connects a charger, so that charger is terminal unit charging.
