Be described in detail with regard to the connected mode of embodiment to above-mentioned communication link wiring below.
Execution mode 1:
Please refer to the drawing 4, execution mode 1 discloses one and uses on handset port, Signal transmissions between the external equipment that can either realize identical CTIA audio interface standard and the Signal transmissions between the external equipment of identical OMTP audio interface standard, can realize again the communication link wiring 400 of Signal transmissions between the external equipment of CTIA audio interface standard and the external equipment of OMTP audio interface standard.
Please refer to the drawing 5 and Fig. 6, there are two kinds of audio interface standards according to the difference of input/output signal host-host protocol in the interface of the handset earphone of prior art: CTIA standard and OMTP standard.The interface definition of each the signal connection end that these two kinds of standards adopt is mutually corresponding, and the difference between them is that the line sequence arrangement between each signal connection end is inconsistent, concrete:
For the external equipment with CTIA standard, its signal connection end is defined as:
Pin1-left channel signals link, Pin2-right-channel signals link, Pin3-grounding connection end, Pin4-microphone signal link.
And for having the external equipment of OMTP standard, its signal connection end is defined as:
Pin1-left channel signals link, Pin2-right-channel signals link, Pin3-microphone signal link, Pin4-grounding connection end.
Based on above-mentioned difference, the communication link wiring 400 of present embodiment has the first joint 410 and the second joint 420 be connected with external audio frequency device signal.First joint 410 and the second joint 420 all have 4 wiring points 411,421 connected one to one with the signal connection end on respective external audio frequency equipment.4 wiring points 411 of the first joint 410 and 4 wiring points 421 of the second joint 420 are connected one to one by selector switch 430.Selector switch 430 has 4 the first pins connected one to one with 4 wiring points 411 of the first joint 410: the first pin A1, the first pin A2, the first pin A3 and the first pin A4, and 4 the second pins connected one to one with 4 wiring points 421 of the second joint 420: the second pin B1, the second pin B2, the second pin B3 and the second pin B4.First pin A1 is corresponding with the second pin B1 to be connected, and the first pin A2 is corresponding with the second pin B2 to be connected, and the first pin A3 is selectable with the second pin B3 or the second pin B4 is corresponding connects, and the first pin A4 is connected with all the other second pin B4 or the second pin B3.
