DIY voice amplifier microphone circuit Loudspeaker Sound detection Explain



Published
The audio signal from the microphone is magnified and output to the speaker. Make a wired phone for remote talking, call each room in the house, make a loudspeaker, increase music without plugging in the device, detect very low sounds, or give an audible intruder alarm. The power circuit increases the sound directly from the microphone, magnifies the signal from the microphone many times and emits it to the speaker, you can add an amplifier circuit to hear it louder. The electronic circuit is simple but the sound is realistic, the voice is amplified and the speaker is still recognized. The circuit uses transistor npn s8050, tip41, resistor, capacitor, optimal DC 12v power source for the circuit to work, with other power sources need to recalculate the resistance values. In the video, I draw a diagram and explain the operating principle of an electronic circuit.
