It is bright, for the ease of description, part relevant with the utility model rather than entire infrastructure are illustrate only in attached drawing.
For clear, clear description various embodiments of the utility model, the realization principle of the utility model is carried out first
It is simple to introduce.For four-section type headset plug the mode of connection there are different standards, be respectively international connection and state's inscribed methods.
Fig. 1 a are the international connection schematic diagram of four-section type headset plug.As shown in Figure 1a, the functional section sequence of the four-section type headset plug
Correspond to microphone, ground connection, R channel and L channel respectively from left to right.When four-section type headset plug insertion and international connection phase
During matched earphone jack, aforementioned four functional section respectively with the microphone pin (being pin 1 in Fig. 1 a) inside earphone jack,
Grounding pin (being pin 2 in Fig. 1 a), left channel pin (being pin 3 in Fig. 1 a) and right channel pin (being pin 4 in Fig. 1 a)
It is connected.According to the above-mentioned mode of connection, there are earth-return circuit, left channel signals and R channel for left channel pin and right channel pin
Signal can be with normal transmission.
Fig. 1 b are state's inscribed methods schematic diagram of four-section type headset plug.As shown in Figure 1 b, the work(of the four-section type headset plug
Energy section sequence corresponds to ground connection, microphone, R channel and L channel respectively from left to right.When four-section type headset plug insertion and state
During the earphone jack that inscribed methods match, aforementioned four functional section (is respectively in Fig. 1 b with the grounding pin inside earphone jack
Pin 1), microphone pin (being pin 2 in Fig. 1 b), left channel pin (being pin 3 in Fig. 1 b) and right channel pin be (in Fig. 1 b
For pin 4) it is connected.According to the above-mentioned mode of connection, there are earth-return circuit, left channel signals for left channel pin and right channel pin
Can be with normal transmission with right-channel signals.But if when the mode of connection of headset plug is mismatched with earphone jack, for example,
The headset plug defined according to international connection, is inserted into the earphone jack defined according to state's inscribed methods, or according to state's inscribed methods
The headset plug of definition, when being inserted into the earphone jack defined according to international connection, left channel pin and right channel pin are not
There are earth-return circuit, so that left channel signals and right-channel signals will be unable to normal transmission.
In the utility model embodiment when headset plug is inserted into earphone jack, microphone is drawn by using connection terminal
Foot is connected with grounding pin, no matter headset plug is using international connection or state's inscribed methods, left channel pin and R channel
