First base stage 221 of audion 180 is electrically connected with, and the first emitter stage 222 of the first audion 180 connects reference power source 250, ginseng
Examine to be connected between power supply 250 and the first base stage 221 of the first audion 180 and have the 7th resistance R700.The of first audion 180
One colelctor electrode 223 connects microcontroller 210, and specifically, the first colelctor electrode 223 is that the detection foot with microcontroller 210 is connected
's.
When portable power source in city or domestic power supply are audio frequency apparatus charging, the output voltages using 5V more.And reference
The voltage of power supply 250 is less than the voltage of extraneous power supply, and with the output voltage of extraneous power supply as 5V, reference power source is that 3.3V is
Example, the operation principle of detection module 220 is: when there being extraneous power supply to connect charging port 104, the reverse input of amplifier 140
The electromotive force of end 142 is 5V, and the electromotive force of the in-phase input end 141 of the amplifier 140 being connected with reference power source 250 is 3.3V, because of
The electromotive force of the reverse input end 142 of this amplifier 140 is more than the electromotive force of the input in the same direction 141 of amplifier 140, now amplifier
The signal output part 143 of 140 exports the low level signal the first base stage 221 to the first audion 180, the first audion
First base stage 221 electromotive force of 180 is the lowest and then makes the first audion 180 turn on.After first audion 180 conducting, reference power source
250 connect conducting, the detection foot of microcontroller 210 between the second colelctor electrode 163 and microcontroller 210 by the first emitter stage 222
Detection obtains the voltage signal of reference power source 250, and now detection module i.e. would know that extraneous plant-grid connection charging port 104,
220 complete to detect after work detection signal are passed to microcontroller 210.
Microcontroller 210 obtains after the signal of feeder ear, can control control module 230 and work, and Fig. 4 is this enforcement
The circuit diagram of control module 230 in the earphone that example provides.Seeing also Fig. 2, Fig. 3 and Fig. 4, control module 230 includes that field is imitated
Should manage and the second audion 160, the outfan of microcontroller 210 connects the second base stage the 162, the 2nd 3 of the second audion 160
Second colelctor electrode 163 of pole pipe 160 connects earth terminal 170, and the emitter stage of the second audion 160 connects the grid of field effect transistor
152, the source class 151 of field effect transistor electrically connects charging port 104, the drain electrode 153 of field effect transistor then with earphone cord 103 be positioned at ear
One end in cover 102 is electrically connected with.It is connected between charging port 104 and field effect transistor and has the 4th resistance R400, and the 4th electricity
Resistance R400 is again connected on the second emitting stage of the second audion 160 and and then connects formation path with earth terminal 170.
The operation principle of control module 230 is: after the first audion 180 in detection module 220 turns on, reference power source
250 turn on microcontroller 210, and the voltage of reference power source 250 acts on the second base stage 162 of the second audion 160, makes second
The electromotive force of base stage 162 raises, and then makes the second audion 160 disconnect, and that is to say, between reference power source 250 and earth terminal 170
Open circuit, the electromotive force of the grid 152 of field effect transistor 150 increases, and field effect transistor 150 conducting makes charging port 104 and charging wire 103
Between electric connection.That is to say the extraneous power supply of conducting and earphone cord 103, and then charge for audio frequency apparatus.
It should be noted that when extraneous music player devices inserts charging port 104, reference power source 250 connection is put
The in-phase input end 141 of big device 140, now the electromotive force of in-phase input end 141 is high compared with the electromotive force of reverse input end 142, and signal is defeated
Go out end 143 output high potential to the first base stage 221 of the first audion 180, the first base stage 221 electromotive force of the first audion 180
Higher, the first audion 180 is in cut-off state, open circuit between microcontroller 210 and reference power source 250 so that reference power source
The voltage of 250 can not act in the second base stage 162 of the second audion 160, and the second audion is in the conduction state, that is to say
Turn between charging port 104 and earth terminal 170.And insert the extraneous music player devices in charging port 104 can be direct
Audio processing modules 110 in earphone obtains music signal and externally plays out.In Fig. 2, arrow represents music signal
Flowing to, referring to Fig. 2, after playback equipment inserts charging port 104, the music play from audio frequency apparatus is through earphone cord
103 are delivered to audio processing modules 110 processes, and on the one hand the music signal after process enters speaker 109, on the other hand
Charged port 104 enters in playback equipment and plays out, it is achieved music sharing, and playback equipment described herein can be sound
The equipment of the band playing functions such as sound, mobile phone, flat board.
In the present embodiment, the purpose of detection module 220 and control module 230 is set in order to realize different utilization voltage
Switching, during because charging port 104 connects power supply, as a example by most of portable power sources on the market, the work electricity of portable power source
Pressure is for 5V, and the outer equipment of putting such as charging port 104 and sound equipment is when being connected, the port exported as music, most with on the market
As a example by number audio output port (AUX out), within running voltage is 3.3V.Detect whether it is sound equipment etc. by detection module 220
Equipment of putting outward accesses, it is achieved export different running voltages.Be equivalent in earphone, be provided with charge mode and music pattern, when
Insert charging port 104 is power supply, then controlled control module 230 startup by microcontroller 210 after detection module 220 detection and fill
Power mode, is the microphone apparatus such as sound equipment when insert charging port 104, then enables music pattern.
Structural representation when Fig. 5 is that in the present embodiment, charging port 104 exports as music, the difference of Fig. 5 Yu Fig. 1 exists
In charging wire 106 has replaced to audio output line 112, one end of audio output line 112 arranges the first headset plug 113,
One end away from the first headset plug 113 of audio output line 112 arranges the second headset plug 114.In the present embodiment, the first ear
The machine transplanting of rice 113 and the second headset plug 114 are standard 3.5mm headset plug, and both can exchange use.When the first earphone is inserted
After 113 insert charging ports 104, the first headset plug 113 is electrically connected with audio frequency processing circuit 110 by charging port 104,
Music signal in audio frequency processing circuit 110 is outwards exported, when the second headset plug 114 and ear by the first headset plug 113
After the equipment such as machine, power amplifier connects, just can share music together with the earphone that the present embodiment provides.
