There are several things I really appreciate in your video. You first show is what type of output that comes in the Oscilloscope. Then we know what we are dealing with. They you develop the most simplified amplifier. No gimmicks, just a simple amplifier. It does a good job. Things work. If it works, cant complain. Enjoyed your video and recommended to my younger brother too! I learnt a lot having a decade experience in electronics and my brother will learn a lot too. Thanks.

What a phenomenal tutorial. You explain things in a way, that makes it easy to absorb, and understand, unlike mainstream academia which teaches in a very sterile, and emotionless manner. Because of you, and the way you connected that Electret Mic to an, "O-Scope", I finally understand the minuscule amount of voltage produced by the Electret, and why one generally needs to add some type of amplification immediately following the Mic. All I can say is Thank You for making learning, intriguing.

I really like this video. You explain why some parts of the circuit need to be modified/upgraded to a better schematic with more components. As far as a video which teaches you the WHY aspect of things, this is second to none. Great job explaining yourself and why you built it the way you did. If only all my teachers I encountered through school explained the WHY part as well as you do in this video! Thumbs Up!

I know this is an old video, but I built your circuit, and I made a correction, to get way more gain and to not cut off the low tones -> replace the 100nF caps with 47uF ones. Much better! Great video by the way :)
@dardosordi4 жыл бұрын
That's a great video. One missing details is that inside the electret capsule there's a usually a JFET transistor doing the initial amplification.
@jovoarezina85848 жыл бұрын
This is awesome! A note: *PLUGIN POWER*! Google it! I didn't know myself about this until a few days ago, but apparently there is around 3V coming from the sound card at the mic plug, specifically to power electrets. I'm not sure of the current capabilities or if you can drive a transistor amp with it, but if you can and it's clean enough this design can be used without external power. I'm thinking of trying to make a passive noise canceling arrangement with two out of phase electrets that can be an add-on mic for headphones.

Really appreciate you building it up as gradually as you can though and showing what comes out at different stages. No one else does that that I can remember. Really helps with the learning.

This reminds me of an amplifier experiment I made a long time ago. It was a 2 transistor, 2 transformer push pull amplifier that I connected a 24inch speaker(with it's own transformer) to the INPUT as a mic. and headphones to the OUTPUT. I was outdoors and could hear someone whisper from 50 feet away.. The amplifier was powered by a 9 volt battery.

At 3:20 you *don't* need to charge a capacitor. The point is that electret material carries a permanent charge. The power source is needed because there's a FET inside the capsule which buffers the signal and reduces the impedance. The first resistor is the drain load of that FET.

Electret mike needs at least 300 microAmperes of bias current. Voltage drop on 10K resistor is 3 volts in this case - which is all supply voltage of 2AA batteries. For such low voltage - 4K7 bias rezistor is better option - that ensures more "voltage room" for mike capsule.
