Abstract:
1. A multifunctional complex power supply device comprises: an anti-countercurrent & voltage-regulation circuit with a rechargeable battery connected in conjunction with a solar battery, a generator and a microphone; wherein there is a first switch mounted in between the solar battery and the anti-countercurrent & voltage-regulation circuit, a second switch erected in between the generator and the anti-countercurrent & voltage-regulation circuit plus a third switch installed in between the microphone and the anti-countercurrent & voltage-regulation circuit; also, the rechargeable battery is linked to a power-consuming gadget; when using the power supply device, selection is available to switchover the first switch to ON-state so that the solar battery is energized to charge electricity to rechargeable battery firstly, and then the rechargeable battery supplies power to the power-consuming gadget; or select to switchover the second switch to ON-state so that the generator is enabled to charge electricity to the rechargeable battery first, and afterward the rechargeable battery supplies power to the power-consuming gadget; or select to switchover the third switch to ON-state with sounds input into the microphone so that microphone can take the advantage of electric energy through the transformation of sound pressure of the input sounds to charge electricity to the rechargeable battery, and then the rechargeable battery supplies this correspondingly charged electricity to the gadget for power consumption.
