circuit diagram


*First you want 1pcs NPN transistor [BC547/BC548]


*Then you want 1 pcs 100k resistor.


*Then short collector to base by this 100k resistor.


* Then you want 10k resistor 


*Then connect this 10k resistor on transistor collector.


*Then you want 104j capacitor.


*Then connect this 104j capacitor on transistor base.


*Then you want 10k resistor.


*Then short 10k resistor to 104j capacitor by this 10k resistor. [connect after watch circuit diagram]. 


*Then you want 104j capacitor.


*Then connect this 104j capacitor on transistor collector.


*Then you want 100uf capacitor.


*Then connect 100uf capacitor [+] on 10k resistor. And capacitor [-] connect on transistor emitter. [connect after watch circuit diagram].


*Then where 10k resistor and 104j capacitor connected, there is MIC input. 

*Where 2pcs 10k resistor connected, there is VOLTAGE input. [9-12 volt DC]

*Where 1pcs 104j capacitor connected, there is AUDIO output.

*And transistor emitter is GND.
