In addition, in order to reasons such as conserve space, the signal output of present many equipment and microphone inlet are integrated into a socket.In some cases, two equipment need reciprocally transmission of audio signal, even if the audio output signal of equipment R can be transferred to the microphone input termi-nal of equipment S by prior art, also cannot when not again fork the audio output signal of equipment S is transferred in equipment R.
Therefore, obtain a kind of the audio output signal that an equipment sends can be realized to be transferred to another equipment microphone input termi-nal and the audio signal transmission wire that can realize transmitted in both directions becomes the target that those skilled in the art pursue all the time.
Utility model content
For solving defect in prior art, the utility model provides a kind of audio frequency cross spider, achieve the object of the microphone input termi-nal audio output signal of an equipment being transferred to another equipment, and when not again fork realize the transmitted in both directions of audio signal.
For achieving the above object, the utility model discloses a kind of audio frequency cross spider, comprise the identical A joint of structure and B joint, be connected by wire between A joint with B joint, A joint comprises input microphone interface, input sound channel interface, input interface of the ground wire, input pickup resistance, input polarity free capacitor, have circuit node P between input microphone interface and input pickup resistance, circuit node P connects one end of input polarity free capacitor; B joint comprises output sound channel interface, output interface of the ground wire, output polarity free capacitor; The other end of input polarity free capacitor connects output sound channel interface by wire, and one end of output polarity free capacitor connects input sound channel interface by wire, and input interface of the ground wire is connected with output interface of the ground wire by wire.
By audio frequency cross spider of the present utility model, can realize the connection between sound signal output device and voice signal recording device, significantly reduce the loss of voice signal, the intensity of signal is high, recording effective.In addition, when two interfaces needing to connect not only had possessed audio signal output function but also possessed microphone input function, audio frequency cross spider of the present utility model can realize transmitted in both directions.
Further, B joint also comprises output microphone interface, output resistance, to connect between output microphone interface with output interface of the ground wire output resistance, have circuit node Q between output microphone interface and output resistance, circuit node Q connects the other end of output polarity free capacitor.
Further, wire is single-core line or split conductor.
Further, wrapped in wire surrounding layer, is conducive to the protection to wire.
Further, A joint and B joint are all 3.5mm plug.
Owing to adopting general 3.5mm plug, its range of application is wider, and application scenario is more, and portability is stronger.
The beneficial effects of the utility model are: the audio frequency of an equipment is directly exported the microphone input termi-nal being connected to another equipment by audio frequency cross spider of the present utility model by wire, the interference in this direct signal transmission form maskable external world, greatly strengthen the purity of signal; And when two interfaces needing to connect not only had possessed audio signal output function but also possessed microphone input function, audio frequency cross spider of the present utility model can realize transmitted in both directions.
In addition, the wire between the joint at audio frequency cross spider two ends of the present utility model also can play the effect extending audio signal transmission distance.
