Yes agree i don't know anything about electronics.
But ,no this gardening statement doesn't suits well on me @ Audioguru because i'm not an Electronic Engineer (I had mentioned in my first post itself) .So its not valid in my case.
I'm just an beginner hobbyist in electronics.
I hope you or...
No problem if its old fashioned. We don;t need an HI-FI precision,we will create an base and later others can improve it on their own skills :-)
But at least we must have an base circuit.desperately waiting for your input .Thanks
@ audiog,
The actual earpiece currently sold on market utilizes LM386 as an audio op-amplifier,i had seen it with my eyes.
yes,i agree that LM4911 got 10 pin's.Actually i said about the actual micro earpiece IC which is being sold on market.
@Sunny,ofcourse yes agree with that.
I can clearly...
Yes, normal people use. We can use for covert operation.
Yes, I had made an loop. lm 386. Instead of speaker I attached enameled wire with 60 turns.
Lol.it has gain of 1. Lol. Oh man, adding that wont increase the size of our earpiece? Just thrown in some proper circuitry man. Oh yesterday...
@ aetosa
,so many people put the effort to help you out man,atleast share your final results and some circuit,this will help others too. cmon man sharing is caring,spread the knowledge.
Because of such non-sharing mindset,people these days don't take interest to help others :< .So much...
Nice to know that you too know him somehow @ sunny. Actually Hutchison is working on free energy these days. He had sold free energy devices to few Japanese industrialist and few of the world's biggest defence contractors, I guess that. He will surely make the free energy concept available to...
Actually I was confused by Chinese advertising & mentioned UHF.
Oh, ok audioguru.Nice to know that aswell.
Piezoelectric earphones ◀ Size matters in our case broda.
Oh ok. Ok brodas, just as final approach, tell me what all parts to order (components).Getting too much hyper on making one...
@ Dan Mills,yes its same as you said:- https://www.digikey.com/product-detail/en/ES-23127-000/423-1115-ND/1646374
I have other plans on speaker,i have an small speaker,similar to this one.Also its as small as that. but its simple speaker an no power amp.Well,that's later part.Our main goal is...
@ Dan Mills,
Hello,well buying defeats the whole purpose of DIY or HOBBY.Yep agree on that class D POWER op-amp. Last time i broke one,tcoil wire pulled outr of circuit along with speaker wire.But if you want i can order one more and snap it here.Well,as for the assembly.I had talked with an...
I must admit, you are too good in electronics as well as explanation. I got the concept you said about supply voltage fall and output sound fall stuff. Amazing. Also agree on that capacitor need.
Well I also know some rumors that other companies copy the texas IC and change few stuff in...
Compared to LM4911 ,what is your thoughts on this ? https://www.ti.com/product/tpa6100a2
Is TPA6100A2 better than LM4911 ?
Also this can work on 1.6-V - 3.6V,whereas LM4911 works on 2V - 5.5V .
which is better for tiny earpiece, LM4911 or TPA6100A2 ?
Oh great, now we get an start. Thanks for the effort and to bear with me @ 'Audioguru'.
Now on mobile, mid night. Tomorrow will find an decent circuit for that IC and post here.
Hey Audioguru,before bed, want to say you thanks. Cya

Being an alien's fan and ufo loving guy...
I see.
NOW with all that said, you got an better circuit or near to one. Can you make circuit a bit better!!
Getting disappointed :<
Edit:
Just got an warning to ask via PM. Ok will ask only via thread. :(
Oh,ok. Can you or anyone mod this to be an better circuit ? Not best but must work normally.With low battery drain and good gain and low distortion.
Any gurus?
