Abstract

The invention provides a data transfer connection system, a mobile terminal, and an adapter device. The adapter device comprises a TYPE-C male plug and an earphone holder wherein the VCONN end of the TYPE-C male plug is connected to the L end of the left sound channel of the earphone holder; the D plus end of the TYPE-C male plug is connected to the L end of the left sound channel of the earphone holder; the D minus end of the TYPE-C male plug is connected to the R end of the right sound channel of the earphone holder; the SBU end of the TYPE-C male plug is selectively connected to the microphone end of the earphone holder or a ground terminal through a first double-pole four-throw switch. The data transfer connection system, the mobile terminal, and the adapter device provided by the invention can automatically recognize and access an OMTP type earphone and a CTIA earphone and has good versatility.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transfer connection system, a mobile terminal and an adapter device. Background technique [0002] At present, more and more new-generation mobile terminals or electronic devices are only equipped with a Type C interface, and the traditional earphone interface is canceled, so that the traditional earphone cannot be directly connected to the mobile terminal or electronic device through the Type C interface. [0003] In addition, there are two traditional earphone interface standards, one is the OMTP standard and the other is the CTIA standard. [0004] see figure 1 , figure 1 It is a structural schematic diagram of an OMTP type earphone and a CTIA type earphone in the prior art. [0005] In OMTP type earphones, 1 is left channel, 2 is right channel, 3 is microphone, 4 is GND; [0006] In CTIA type earphones, 1 is the left channel, 2 is the right channel, 3 is GND,...
