Model IN4001 of diode D1.Triode V1 and triode V3 are PNP triode.Diode D2 position voltage stabilizings
Diode.Triode V2 is NPN triode.
The present invention operation principle be：Electric energy is entered by the USB interface of computer in this circuit, from USB interface J1 just
1 pin output voltage of voltage output end, resistance R3 and resistance R4 composition division modules, when voltage is normal, the voltage after partial pressure is by two
Pole pipe D2 punctures, and the base stage of triode V2 obtains electric by resistance R3 and diode D2, triode V2 conductings, and voltage is through diode
It is charged to battery E after D1 and triode V2, while the base stage of triode V1 obtains electric by resistance R1, therefore V1 does not lead
Logical, loudspeaker B does not work, and electric capacity C1 is also carried out charging, run into USB break down cause for it is electrically disconnected when, the base stage of triode V1
Loss of voltage, electric capacity C1 are discharged to V1 by resistance R2, therefore V1 conductings, and loudspeaker B sends power failure chimes of doom, and triode V3 is short
Road protection element, under normal circumstances, the base stage of triode V3 has trigger voltage, therefore V3 cut-offs, when running into E appearance short circuits, three
The base voltage of pole pipe V3 is shorted, therefore V3 conductings, and triode V2 ends because losing conducting voltage, stops the charging to E,
Reach the purpose of short-circuit protection.
