Description
Technical field
The utility model is related to audio automatic checkout system more particularly to it is a kind of can the earphone of free switching audio output insert
Head.
Background technology
In the prior art, the automatic checkout system of the equipment such as TV needs the institute to including loud speaker output, earphone output
There is channel to be detected, still, in traditional design, being inserted into rear speaker in headset plug can be muted.Prior art middle ear
The machine transplanting of rice enters the principle that rear speaker channel is muted：Mute control terminal is provided on the earphone socket of existing audio frequency apparatus, it should
Mute control terminal be pulled up under normal conditions resistance it is clamped on 3.3 volts of level namely loud speaker output sound, traditional three
Segmentation headset plug generally includes L channel (L) output terminal, right channel (R) output terminal and ground terminal, when the ear of audio frequency apparatus
After being inserted into earphone on machine transplanting of rice seat, the mute control terminal on socket enters ground by the ground terminal short circuit of headset plug, and voltage becomes 0 volt,
Speaker Quiet.
So being not only detected to realize to earphone output channel but also loud speaker output channel being detected, then need
To realize that the sound of earphone channel or loudspeaker channel exports, and then realization detection respectively by the plug of earphone.However, it inserts
Pull out the process of earphone need it is artificial carry out manually or automatically control plug using automation equipment, process it is relatively complicated and into
This higher, poor reliability.
Utility model content
The purpose of this utility model is that the above-mentioned problems in the prior art is solved, to traditional three-section earphone plug
Structure be improved, introduce four-section type headset and be inserted into, and be equipped with switch control unit, realize and opened with simple switch or relay
The mode of pass carries out the switching of audio frequency output channel.
To achieve these goals, the technical solution of the utility model is：
It is a kind of can free switching audio output headset plug, the plug be four-section type headset plug, the four-part form
The port of headset plug includes L channel end, right channel end, ground terminal and switch terminal, connects between the ground terminal and switch terminal
It is connected to switch unit；When the four-section type headset plug is inserted into socket, the switch terminal is used to connect the mute of earphone socket
Control terminal, L channel end, right channel end and the ground terminal of the headset plug respectively with the L channel end of earphone socket, right channel
End and ground terminal.
Preferably, the switch unit includes manual mechanical switch or self-action relay switch.
Compared with prior art, the utility model has the following advantages：
1st, the utility model only needs simple switching manipulation that audio output can be realized in earphone channel and loudspeaker channel
Between free switching, without artificially plugging headset plug, simplify the testing process to audio frequency output channel.
2nd, due to that need not plug headset plug, the utility model can extend the use longevity of receiver J-Horner to a certain extent
Life, avoids frequently plugging, and reduces contact resistance, improves sound quality.
3rd, the utility model has the advantages of simple structure and easy realization, of low cost.
Description of the drawings
Fig. 1 be the utility model can free switching audio output headset plug structure diagram；
Fig. 2 is the earphone socket port organization schematic diagram of specific embodiment of the present invention.
Specific embodiment
In order to be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, under
Face combines and is specifically illustrating, and furthers elucidate the utility model.
As shown in Figure 1, the utility model can free switching audio output headset plug for four-section type headset plug, institute
The port for stating four-section type headset plug includes L channel end L1, right channel end R1, ground terminal G1 and switch terminal C1, the ground wire
Switch unit K1 is connected between the G1 and switch terminal C1 of end；Switch unit K1 in present embodiment uses Manual mechanical
Switch, can also be used automatic control type relay switch or other all can realize the switch electricity of connecting and disconnecting of the circuit function
Road.
As shown in Fig. 2, the audio frequency apparatus of specific embodiment of the present utility model uses XS606 audio frequency apparatuses, the audio
The socket port of equipment includes L channel end L2, right channel end R2, ground terminal G2 and mute control terminal C2, shown mute control
End is connected to 3.3V positive poles, while pass through a load resistance W2 connections by the pull-up resistor W1 that a resistance value is 4.7K ohm
In external output circuit, the resistance value of load resistance W2 is 100R.Under normal conditions, when no headset plug is inserted into, mute control
It is clamped on 3.3V voltages that end C2 processed is pulled up resistance W1, is at this time loud speaker output mode.
When needing to be detected the audio frequency output channel of audio frequency apparatus XS606, by the utility model as shown in Figure 1
Four-part form plug be inserted into the socket port of audio frequency apparatus XS606 shown in Fig. 2, the switch terminal C1 connections earphone socket at this time
Mute control terminal C2, L channel end L1, right channel end R1 and the ground terminal G1 of the headset plug respectively with earphone socket
L channel end L2, right channel end R2 are connected with ground terminal G2, i.e., 1,2,3,4 feet in Fig. 1 and Fig. 2 are connected respectively.If it needs
Loudspeaker channel be detected, then disconnected switch unit K1, the mute control terminal C2 of audio frequency apparatus XS606 is pulled up electricity
Resistance W1 is clamped on 3.3V voltages, speaker voice giving, and earphone channel is mute；When needing to be detected earphone channel, then will
Switch unit K1 is closed, mute control terminal C2 and ground terminal G2 or the G1 short circuit of audio frequency apparatus XS606, and the voltage of C2 ports is
0V, at this point, loud speaker is muted, earphone channel sounding.Thus it realizes and realizes that audio signal is being raised one's voice by simple switch
Free switching between device output channel and earphone output channel without plugging earphone, simplifies audio frequency output channel detection
Flow, extend the service life of audio output port, improve sound quality.
It should be noted that the utility model can also be applied to other audio frequency apparatuses with earphone socket, and not by
It is limited to specific embodiment of the present invention.
The characteristics of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
