Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is specifically illustrated, accompanying drawing is only for reference and explanation is used, not structure
The limitation of paired the utility model scope of patent protection.
It refer to Fig. 1 to Fig. 3, a kind of bluetooth earphone with wired function of the utility model, including：Headphone unit 1, company
Wiring 2, master control set 3, charging wire 4 and audio connecting cord 5, wherein, described one end of connecting line 2 is connected with the headphone unit 1,
The master control set 3 is connected with the other end of connecting line 2, and USB interface seat 31, institute are provided with described one end of master control set 3
Audio connecting cord 5 and the charging wire 4 is stated to be connected with the master control set 3 as desired by USB interface seat 31.Specifically
Ground, charged thing, and the USB interface seat 31 is connected with the charging wire 4, when wireline mode plays music, the USB interface seat 31
It is connected with the audio connecting cord 5.
Further, noise reduction unit 21 is provided with the connecting line 2, the noise reduction unit 21 is ANC noise reduction units, institute
State be additionally provided with connecting line 2 slip guard member 22, it is described slip guard member 22 connecting line 2 is drawn close in one,
User can also can adjust the length that two tramlines are opened on the connecting line 2 by sliding the slip guard member 22, be easy to use.
The noise reduction unit 21 improves tonequality of the present utility model.
Circuit board is provided with the master control set 3, the outside of master control set 3 is provided with what is be connected with the circuit board
It is provided with solar panel 32, the circuit board on charging circuit 3a, the charging circuit 3a and is provided with oscillating circuit mould
Block 3a1, the voltage changing module 3a2 being connected with the oscillating circuit module 3a1, and the battery being connected with the voltage changing module 3a2
Switching Power Supply pipe VT1 is provided with 3a3, the oscillating circuit module 3a1.The area of the solar panel 32 be 6cm ×
6cm, the idle voltage output of each solar panel 32 is 4V, and the number of the solar panel is 4.It is described
Function button is provided with master control set.Further, the charging circuit 3a is after plus input power, and electric current is through resistance R1
Switching Power Supply pipe VT1 base stage is flowed to, Switching Power Supply pipe VT1 is turned on.After Switching Power Supply pipe VT1 conductings, primary line
Enclose Np and just add input direct voltage, collector current Ic linear increases in Np, feedback coil Nb produces 3 positive 4 negative sensings
Voltage, makes Switching Power Supply pipe VT1 obtain base stage just, to launch extremely negative positive and negative feedthrough voltage, the voltage is through electric capacity C2, resistance
R3 makes Switching Power Supply pipe VT1 collector current further increase to Switching Power Supply pipe VT1 injection base currents, and positive feedback is produced
Avalanche process, makes Switching Power Supply pipe VT1 saturation conductions.During Switching Power Supply pipe VT1 saturation conductions, transformer T1 passes through primary
Coil Np stores magnetic energy.At the same time, induced voltage charges to electric capacity C2, with increasing for electric capacity C2 charging voltages, switch electricity
Source capsule VT1 base potentials gradually step-down, when Switching Power Supply pipe VT1 base current change, which can not meet it, continues saturation, is opened
Powered-down source capsule VT1 exits saturation region and enters amplification region.Switching Power Supply pipe VT1 enters after magnifying state, and collector current is by amplifying
Maximum before state declines, and produces 3 minus 4 positive induced voltages in feedback coil Nb, subtracts Switching Power Supply pipe VT1 base currents
Small, collector current reduces therewith, and avalanche process occurs again in positive feedback, and Switching Power Supply pipe VT1 ends rapidly.Switching Power Supply
After pipe VT1 cut-offs, the energy of transformer T1 storages is supplied to load, and the 5 minus 6 positive voltages that secondary coil Ns is produced are through diode
After VD1 rectifying and wave-filterings, DC voltage is obtained on electric capacity C3 to the battery charging in the master control set 3.In Switching Power Supply pipe
When VT1 ends, 3 minus 4 positive voltages of the defeated people's voltage of direct current supply and Nb sensings are again reverse to electric capacity C2 through resistance R1, resistance R3
Charging, gradually steps up Switching Power Supply pipe VT1 base potentials, it is turned on again, and upset again reaches saturation state, and circuit is with regard to this
Sample repeats vibration and gone down.By setting the solar panel 32 and the charging circuit 3a so that the utility model has
Easy to use the characteristics of.
The two ends of charging wire 4 are provided with USB interface, and described one end of audio connecting cord 5 is provided with the first USB interface
51, the other end of audio connecting cord 5 is provided with audio connector 52.
From the above, it can be seen that a kind of bluetooth earphone with wired function of the present utility model, by setting
Master control set 3 is stated, original audio input line is merged into the charging wire 4 and the audio connecting cord 5 two by 4 lines
Line, is connected on the master control set 3 with selecting a mode, then the function of realizing charging and listen song can be corresponded to, in addition, in the master
