Circuit Description
|
This circuit is mainly composed of an audio amplifier circuit and a bistable trigger circuit. Q1 and Q2 form a two-stage audio amplifier circuit. The audio signal received by the MIC is coupled to the base of Q1 via C1. After amplification, the collector directly feeds the base of Q2, and a negative square wave is obtained at the collector of Q2. To trigger the bistable circuit. R1
and C1 limit the circuit frequency response to about 3 kHz for a high sensitivity range. When the power is turned on, the state of the bistable circuit is Q4 cutoff, Q3 is saturated, and LED1 is not lit. When the MIC receives the control signal, it outputs a negative square wave after two stages of amplification. After the differential processing, the negative spike is applied to the base of Q3 through D1, so that the circuit is quickly flipped and the LED is illuminated. When the MIC receives the control signal again, the circuit flips again and the LED goes out. If the LED lamp circuit is connected to other circuits, the sound control of other circuits can be realized through J2. |
