@@johncochran8497Id imagine big tech companies get them slightly cheaper

@@johncochran8497really? Is that incuding overseas wholesale? Like china, taiwan, bagladesh, etc. i feel like it should be WAY cheaper than 44 cents

@@indianumberonecountry That's the price that digikey sells them. Obviously, digikey purchases then at a lower price since they do have to make a profit after all. My own experience is that the price roughly doubles for every set of hands it passes through, so I'd expect the price digikey pays to be about 22 cents. And I'd seriously doubt that there's three more sets of hands between digikey and the manufacturer in order to get that approximate one cent price point.

How somebody figured this out I may never understand. Even with this explanation, I don't really get it lol

You need to read up about capacitance and energy/information transduction & transformation. Aka physics dawg!

The only reason electronics are so cheap is because they are the world governments biggest tool to control us. Think about everything you buy and what it costs. Do you really think it makes sense this earbud is cheaper than a mop

Hi there, electric-electronics engineering student here. Someone didn't figure it out, it's like tons of people found different things and thousands of companies and people did develop it into a better product. It's too much for one to perfectly make a product like this. You have what have been developed before within years and the knowledge gathered from around a hundred of years to put on. Of course it's still impressive to come up with a newer thing but such products don't come to life by someone or just in a few years after all. It's hard work for tons of people. @@someguy4489

yes! absolutely amazing. i was just thinking no matter how in depth someone can explain it it’s still crazy

It's an alarmingly simple process when you know the mechanics of it, but how we got to understand that is the part that impresses me. But, technology has a way of making you forget just what exactly you're dealing with from a basic perspective. Most people probably don't think much of a smartphone, but it's effectively pure rare metals, minerals, and essence of dinosaurs powered by man-made lightning that uses light-speed pulses and audio waves far, far beyond our hearing to allow distant communication and access to all human knowledge in seconds. Imagine explaining this to the richest person on earth 200 years ago. There's no way they could conceive of what you're saying. And, of course, by the ever-increasing speed of advancement, something that will be made 50 years from now is probably impossible for us to currently conceptualize. That's the part that fascinates me.

@@CosmicWaltz7you indeed waltz with the cosmos

The core of understanding the process of converting the sound wave into the digital domain is the Fourier transform, particularly DFT analysis.

​@@CosmicWaltz7it's always nice to scroll through KZfaq comments and see comments like yours, instead of most of the rubbish that I normally see. It's actually refreshing seeing thoughtful comments.

I honestly only got to do that when we had to make a somewhat innovative technological prototype for school. Now I get to appreciate our advancements more because we went from just having chemicals, minerals, rocks, and elements, to creating videos and the internet and touchscreen gadgets. It's amazing, how something that would normally just be something to imagine and dream about is actually possible. There are many things that seem impossible to me even now, like how th is it possible to be able to interact with the contents inside a screen, and the technology behind earphones and planes and cameras and videos. Everything we have now is so amazing. We went from nothing to everything. Imagine, before there were only paintings to keep portraits, and early in the 19th/20th century we were able to capture reality and view it.. and then it evolved to videos, a moving picture that is seamless.. And there's also audio. Before we only just heard, and now we get to capture the voices, the sounds of reality and store it for however long we want to. It's amazing. We have come sooo far. Humans are really amazing.

Yep, cover of my microelectronics circuit books had one. Used as the sensor for airbags as well as determining the direction your phone is. Fun fact, the accelerators in your phone are claimed not to be able to be used as microphones lol.

Yes those are called MEMS devices. Very intricate piece of machinery. They physically move just like this microphone. That's how your phone knows its own orientation and acceleration. These accelerometers are 2mm^2. There's a video on YT detailing this in detail. Impressive feat of engineering.

@@SahilP2648 To me, MEMS gyroscopes are even more amazing that accelerometers. Instead of rotating like regular gyroscopes, they vibrate and sense the coriolis force when they are rotated.

What’s that mode? I’ve never seen it

Regular Airpods don't have this feature, they don't really need it since you can hear around them but because Airpod's Pro create a seal in your ear they use a transparency mode to allow you to hear your surroundings through them. If you have Airpod's Pro then under settings you should see noise control and you can switch between transparency and noise cancellation. @@byu2

While I somewhat share the sentiment, for whatever sound these capture to be of any use, some ancillary tech and infrastructure (such as ICs, batteries, storage and/or radios, etc.) are still needed, and while those can also be (and indeed are) miniaturized, they do add up to the cost and the logistics of planting them and making use of them.

​@@detslutarmedLiterally what I was thinking. They probably just realized the improbable and figured out that hiding the tech wont cut it. Now people will even pay for the tools to spy on them, repair or replace the broken units and buy a fricking upgrade every couple of years or so WITH THEIR OWN MONEY. Humans can be literally hacked with the concepts of property and possessions. You dont need to hide the poison and your tools to spy on somebody. Just start selling those to people and they'll do the rest.

@@detslutarmed here's the funny and creepy thing: it's more likely that those interests were determined not by recording your or your friends' voices, but by using really clever algorithms that do anticipate your wants and needs through other means… Yes, a lot of it comes down to basic triangulation, e.g. if friend x tells you “hey, I watched cool video y/bought product z”, all your social media websites have to do is know where you are, figure out *who* you are with, and start suggesting stuff from *their* history, because it's likely that you share similar interests or will be exposed to theirs. It's creepy to the point of being completely stupid, but hey, they must've figured out that people have a really high tolerance to creepy algorithmic behaviour and that it actually works and translates into engagement/sales/whatever.

English is a bizarre language.

@@NoeOfPortland Math is the foundation for everything, even other STEM fields like chemistry and even socioology. History is important for obvious reasons. Don't need to replace them, we could add more core subjects. Problem is it wouldn't help you pack packages in a warehouse, so we only get basic curriculums sadly.

And a Stereoscope to see a Stereo 😅

You're remembering incorrectly. Microphones and speakers are functionally the opposite. Speakers tranduce electricity into sound, while microphones tranduce sound into electricity.

@@ChaceBonanno remember, every action has an opposite reaction. For a speaker, pushing waveforms through a wire causes a magnet attached to a diaphragm to move accordingly. Likewise, if you impart waves upon the diaphragm manually, it will cause the magnet to put waveforms back into the electrical wires. With an amplifier, you *can* read this signal, meaning that speakers are, no matter how horribly functional, in essence, microphones.

They can hear my farts while I sleep

Approximately the size of that airpod maybe fatter especially if u want long battery and long audio recorded but yes, not too crazy big cause wouldn’t need Bluetooth modules or speakers or nothing just the small mic, storage, battery and about 4 chips

​@@v.j.1017this type of information need to be prioritize in public education rather than history or math cause no generation knows what milliamperes are even tho it's something that everybody knows a little bit about from every day usage

@@NoeOfPortland I appreciate your perspective, @NoeOfPortland. Incorporating practical tech education into the curriculum could indeed be beneficial, as it aligns with the increasingly digital nature of our world. Having a foundational understanding of electronics, such as the implications of milliamperes on battery life, can empower us to make informed decisions about the technology we use daily. As someone delving into computer systems in post secondary, I've seen firsthand the value of such knowledge and believe it complements traditional subjects by providing a more holistic educational experience. There just needs to be more effort from everyone. kids need to study more, teachers need to teach better that way we can use our abilities and our brains to their full extents, I believe we should learn history, math, science and technology and we should also focus on innovation but broad innovation.

There’s actually a smaller mic with about the same battery life, but much smaller than that. Your house could have one and you will never know, no matter how much you clean, you’ll never find it.

Id say ion boring but it could also be done with a chemical etch or any combination of either process. As we see membrane separations that should give you a hint 😘

Manufactured "bottom up" in layers. They would have used some kind of sacrificial layer to provide the spacing between top/bottom. Probably a layer of silicon dioxide glass. So you etch the first pattern, deposit a layer of glass, deposit the next layers of poly-Si, then finally etch out the sacrificial glass layer (using HF or plasma). Once all that was done, they probably flipped the entire wafer over and did backside DRIE etching.

isn't the military still running windows 3.1 or something

It’s actually about 50 years ahead.

Little known fact the government actually writes all scientific papers 30 years in advance. They send a tiny ghost into the future to look over your shoulder

Do you think the US govt already had 1810's technology during the signing of the declaration of Independence?

Do you think government had 5-7nm fabs 30 years ago?

Because you can have a microphone, but the microphone by itself cannot function without a battery, connectors, storage unit, etc. It starts to add up quickly, just like a car! You can have the engine, but it won't do anything without everything else.

@@hamzasami8362 Yes, technically you would probably be able to see it. But once you factor in some basic camouflage, *nobody* is going to find it. That's just a fact of life now. And that's ignoring the obvious point that we *knowingly* surround ourselves with microphone devices connected to the internet. Privacy is dead. I'd love for you to prove me wrong.

@SubjectiveObserver Sure, let's take hidden cameras that are often used by stalkers in hotels. They're often not uploaded directly to the cloud because of the small discrete places they are hidden. They're left there for a long time running only on battery till death, and store their videos on a memory card, probably being a MicroSD being the smallest there is currently for the people's use. Why can't they do otherwise? Wifi requires an antenna plus a bigger onboard motherboard that has to be binded to a server that is either a satelight or the hotels wifi which would be rather difficult to set up, this means the camera is going to be much larger as whole due to the nature of more components, ETC ETC. I'm not going to reply anymore to this dumb argument
