Management module, the charge management module realize the direct current of power supply adaptor output to the standby battery charging and
The direct current of standby battery output charges to mobile phone；It further include converter, the converter includes one group of electronics conversion
Switch inputs the mutual conversion with output to its electronic commutator by the control of single-chip microcontroller, realizes the first plug and second
Audio and charging and data interchange between socket.
In the present invention, due to converter, realizing that audio and charging and data are mutual between the first plug and the second socket
It changes, in this way, the second socket of back splint battery can also transmit data or audio signal in back splint battery to when the mobile phone is charging,
Meet user demand.
Further, in above-mentioned mobile phone back splint mobile power source: the charge management module includes charging and boosting pipe
Chip is managed, the 5VDC of adapter is depressured the reserve battery charging for 3.6V with boosting managing chip by the charging, by 3.6V
Reserve battery output voltage boosting at 5VDC be mobile phone power supply and be charging mobile phone battery.

Specific embodiment
Embodiment 1, as shown in Figure 1, the present embodiment is a kind of mobile phone back splint shifting transmitted with audio transmission and charge data
Dynamic power supply, has the first plug to connect with mobile phone jack and the second socket to connect with the plug of power supply adaptor, including standby
With battery, charge management module, the charge management module realizes the direct current of power supply adaptor output to described standby
It is charged with battery and the direct current of standby battery output charges to mobile phone；Enter this in the direct current of power supply adaptor output
Such as detect that preferential handset device charges when having mobile phone to be accessed at this time after product, if this equipment detects insertion
When port is data line or audio class product (such as earphone), at this moment single-chip microcontroller will start converter, and converter is as shown in Figure 3
Including one group of electronic commutator, the mutual conversion with output is inputted to its electronic commutator by the control of single-chip microcontroller, it is real
Audio and charging and data interchange between existing first plug and the second socket.
Charge management module is as shown in Fig. 2, include charging and boosting managing chip U1, charging will be fitted with boosting managing chip
The reserve battery that the 5VDC decompression of orchestration is 3.6V charges, and it is mobile phone confession that the reserve battery output voltage of 3.6V, which is boosted into 5VDC,
Electricity and be charging mobile phone battery.Charging provides the power supply of battery and the power supply of mobile phone with boosting managing chip U1 respectively.Such as Fig. 2
B+ shown, that the 15th foot BATS of this charging and boosting management IC connect, B+ is cell voltage here.What the 16th foot and 17 feet connect
Vin is the input voltage of external charger, that is, 5VDC, it is the charging voltage of power supply adaptor output.It is logical that there are also 20 feet
Crossing the Vin that the high-pass filtering circuit that capacitor C9 and resistance 17 form connects is also that the second socket J2 is obtained from external power supply adaptor
The VOUT of the operating voltage obtained, the 14th foot and the output of 8 feet is exactly to pass through the first plug J1 to input to mobile phone power supply use.Because the
The output of two socket J2 external power supply adaptor is 5V, and the voltage of used standby battery is 3.6V, so to standby
When being charged with battery need be depressured charging, standby battery be mobile phone power supply be because, standby battery voltage be 3.6V, and
The power supply of mobile phone needs 5V, so needing to carry out boosting processing.
As shown in figure 3, chip U9 and chip U10 is converter.Transducing audio and charging and data interchange respectively, pass through list
The control of piece machine inputs the mutual conversion with output to electronic commutator.
As shown in figure 4, being MCU and peripheral circuit, chip U3 is MCU, controls electricity respectively in conjunction with peripheral circuit and exchanges
Audio use, input and the control of output links also detect electric current etc. multifunctional use simultaneously.
It further include hardware protection in the mobile phone back splint mobile power source with audio transmission and charge data transmission in the present embodiment
Circuit, output charging decoding circuit and charging audio decoding circuit etc..
As shown in figure 5, chip U7, chip U8 and chip U2 are hardware protection system, and in the present embodiment, hardware protection system
Respectively include super-charge super-discharge over-voltage and over-current etc. protection.
As shown in fig. 6, chip U5 is the special chip that output charging decoding uses, realizes and led in charging with mobile phone
Believe work.
As shown in fig. 7, chip U6 is charging audio decoder chip, in charging by the audio signal of mobile phone output from back splint
It is exported in second socket of mobile battery, carries out communication exchange with charger and earphone respectively.
