This circuit mainly consists of audio amplifier circuit and bistable trigger circuit.
Q1 and Q2 secondary audio amplifier circuit, by the MK1 receive audio signals via C1 coupled to the base of Q1, enlarged by the collector feed directly to the base of Q2, collector in Q2 got a FuFang wave, is used to trigger the bistable circuit.R1, C1 limit circuit frequency response for high sensitivity in about 3 KHZ range.When power on, the state of the bistable circuit for Q4 deadline, Q3 saturated, D3 is not bright.When the MK1 receives the control signal, after two stage amplifier output FuFang wave, after dealing with the differential negative spike through D1 to Q3 at base, make the circuit flip quickly, D3 lit up.When the MK1 again received a control signal, circuit and flip, D3 put out.Circuit board reserved terminal J1 to meet external control equipment, can be connected through the J1 relay voice control on other devices.(answer the relay to the relay coil at both ends and a diode)
This circuit USES 5 v dc voltage power supply, LED dies machine current 3 mA, leds light up when the current is 6 mA.
