Number；When switch unit 103 is in the second place, the first channel interface connects voice output unit by switch unit 103
106, second sound channel interface, switch unit 103 and button 104 are sequentially connected in series, and wherein voice output unit 106 plays the first sound channel
The voice signal of interface input.Specifically, the first channel interface and second sound channel interface are that the L channel on existing earphone connects
Mouth L and right channel interface R, voice output unit 106 include left ear loudspeaker and right ear speakers, are used for hand in the head circuit
During machine, left channel interface L connects left ear loudspeaker by switch unit 103, and right channel interface R is connected by switch unit 103
Right ear speakers, loudspeaker play the voice signal of left channel interface L and right channel interface R inputs；It is used in the head circuit
Intercom in use, the first channel interface directly by switch unit 103 connect voice output unit 106, second sound channel interface,
Switch unit 103 and button 104 are sequentially connected in series, because sound input unit 105 and audio output interface 102 connect, are worked as
When persistently pushing button 104, the voice signal that sound input unit 105 inputs can be sent to other side and listened to by intercom, real
Existing intercommunication, after button 104 are unclamped, intercom stops sending voice.
Fig. 2 is according to the circuit diagram of the head circuit of the utility model embodiment, as shown in Fig. 2 being preferable to carry out at one
In mode, above-mentioned switch unit 103 is double-point double-throw switch, the first contact 201 and the second contact 202 of the double-point double-throw switch
For the first terminals of double-point double-throw switch, the 3rd contact 203 and the common port that the 4th contact 204 is double-point double-throw switch, the
Five contacts 205 and the second terminals that the 6th contact 206 is double-point double-throw switch, the one end of the 5th contact 205 connection audio output
Interface 102, other end connection sound input unit 105.In the present embodiment, sound input unit 105 is microphone 209,
Electric signal is converted to for receiving voice signal, and by the voice signal, audio output interface 102 is microphone port MIC, is used
In the electric signal for receiving the transmission of microphone 209.
As shown in Fig. 2 when switch unit 103 is in first position, the 3rd contact 203 is connected with the 5th contact 205, the
Four contacts 204 are connected with the 6th contact 206 so that left channel interface L, the second contact 202, left ear loudspeaker 207 are sequentially connected in series
Connection；Right channel interface R, the first contact 201, the 6th contact 206, the 4th contact 204, the company of being sequentially connected in series of right ear speakers 208
Connect；Microphone port MIC, the 5th contact 205, the 3rd contact 203, button 210 are sequentially connected in series；Now it is used for handset earphone
Use, left channel interface L and right channel interface R receive voice signal, and the voice signal is passed through into left ear loudspeaker 207 and the right side
Ear loudspeaker 208 plays back, and call when, sound passes to microphone port MIC by microphone 209, when press by
After key 210, although microphone 209 can receive voice signal, it is shorted, therefore microphone port MIC can not be received
The voice signal of input, headset are learnt the down state of button 210, hung up the telephone, and terminate call, wherein headset includes non-wear-type
(including bilateral, unilateral headset), ear type etc..
As shown in Fig. 2 when switch unit 103 is in the second place, the 3rd contact 203 is connected with the first contact 201, the
Four contacts 204 are connected with the second contact 202 so that left channel interface L, the second contact 202, left ear loudspeaker 207 are sequentially connected in series
Connection；Left channel interface L, the second contact 202, the 4th contact 204, right ear speakers 208 are sequentially connected in series, i.e. monophonic ear
Machine；Right channel interface R, the first contact 201, the 3rd contact 203, button 210 are sequentially connected in series.Now head circuit be used for pair
Say that machine uses, now the voice signal of reception is passed to wheat by second sound channel interface equivalent to PTT keystroke interfaces, microphone 209
Gram wind port MIC, when pushing button 210, intercom can just send speech to other side, therefore make as intercom earphone
Used time, when needing persistently to talk, it is necessary to persistently push button 210, when unclamping button 210, intercom stops input language
Sound, now user can pass through left channel interface L, left ear loudspeaker 207 and right ear speakers 208 receive other side's voice.
In a preferred embodiment, above-mentioned head circuit also includes common port, and sound input unit 105, sound are defeated
Go out unit 106 and button 104 is connected to common port, the common port is earth terminal GND, for by voice output unit 106, sound
Sound input block 105 and button 104 are connected to ground wire, and earth terminal, which can avoid voice signal from being interfered, to be influenceed to use.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
