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.

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.

Thanks for that. I was a record company house engineer in the 80s and 90s, so felt I knew quite a bit about how microphones work. I just assumed earbud/phone mics were simple standard piezo-electric jobbies, but it turns out they’re a little more complicated than that, even though they use the capacitive effect. I’m gonna do a bit more searching about this, it seems the tech has moved on since I was working in audio and it still fascinates me.
MEMS technology. I got a pair of Aurvana Ace 2 earbuds which utilize this tech as a speaker to reproduce mids and highs. The sound reproduction is far superior to old school drivers. The music literally comes alive...they're awesome.
It's not. It's only up to 22khz (this one, i guess, even lower). It's pretty easy for electronic devices to vibrate and transmit 22.000 times per second. The GHZ range is impressive, tho.
To be a contrarian to the other replies, I agree. The fact that we're able to replicate ears and voices at such a small level is incredible. There's also cameras to replicate eyes and tiny ones are used in medical areas to see inside the digestive system for problems.
@@gumbitoicic9977It's all just math. Sound is a series of waves superimposed over each other to form different pitches and timbres. The ability to produce these sounds is less impressive than the ability to record them IMO. Developing the means to take the analog wave created by fluctuations in an electromagnetic field and alter a physical medium such that its own EM field can be used to reproduce that sound at a later time is absolutely crazy. But that's what cassette tapes do.

And even if you could explain it to them, and they completely understood, they still wouldn’t be able to duplicate it in their lifetimes. It would take generations to reproduce the material and manufacturing technologies behind it.
It's incredible that, with silicon, we can make MEMS (microelectronic mechanical devices) to do almost any measurement. Accelerometers, gyroscopes, thermometers, microphones, and so on. That gyroscopes, normally, rotating flywheels, can be made from silicon microchips is, to me, truly amazing. Silicon gyroscopes don't rotate but vibrate instead.
Technically I think thermometers aren't MEMS, just thermistors. (Ie basically a lump of something that changes resistance with temperature, no moving parts)

The ability of the tiny bud to create 3d audio with no latency. They even have a mode now where they will turn down your music if they detect that someone is trying to talk to you. Amazing tech.
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

@@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.

Y'know what's funny to think about...miniaturization doesn't just benefit the consumer, it benefits the company as well. Less materials used to manufacture something which means lower cost to them, and lower weight saves on transportation costs, which are a significant fraction of the end user cost for any item.
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.

Fun fact: all microphones are speakers, and all speakers are microphones, IIRC. They work horribly, but if you can push enough energy through the membrane of a speaker, its movement will apply signal to the wires, just like a microphone.
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.
Is the top layer deposited on the stationary layer after the hole are etched? Or is the whole thing manufactured the other way around and glued shut, since then you could do the ion etching for the cavity beneath?
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.
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

Why can't they do otherwise?

Sometimes you need to take a step back and appreciate how insanely complex our technology has gotten over the years.
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.

Thanks for that. I was a record company house engineer in the 80s and 90s, so felt I knew quite a bit about how microphones work. I just assumed earbud/phone mics were simple standard piezo-electric jobbies, but it turns out they’re a little more complicated than that, even though they use the capacitive effect. I’m gonna do a bit more searching about this, it seems the tech has moved on since I was working in audio and it still fascinates me.
Thanks for sharing some information from the older days.
MEMS technology. I got a pair of Aurvana Ace 2 earbuds which utilize this tech as a speaker to reproduce mids and highs. The sound reproduction is far superior to old school drivers. The music literally comes alive...they're awesome.
Capacitor microphones aren't new
😊😊😊😊
We take mics and speakers for granted. To reproduce complex sounds so well is mind blowing
Complex sounds are truly just many simple sounds so
Well, not really. Speaker is just a coil that moves a membrane and microphone is basically a membrane that moves the coil
It's not. It's only up to 22khz (this one, i guess, even lower). It's pretty easy for electronic devices to vibrate and transmit 22.000 times per second. The GHZ range is impressive, tho.
To be a contrarian to the other replies, I agree. The fact that we're able to replicate ears and voices at such a small level is incredible. There's also cameras to replicate eyes and tiny ones are used in medical areas to see inside the digestive system for problems.
@@gumbitoicic9977It's all just math. Sound is a series of waves superimposed over each other to form different pitches and timbres. The ability to produce these sounds is less impressive than the ability to record them IMO. Developing the means to take the analog wave created by fluctuations in an electromagnetic field and alter a physical medium such that its own EM field can be used to reproduce that sound at a later time is absolutely crazy. But that's what cassette tapes do.
Absolutely love the visual detail along with the well explained concept of how it works.
Thank you!! I've been wondering about this for a while now
It all started with a theoretical physicist coming up with a concept then a clever engineer understood it and applied it and bam you get these kinds of amazing technology

Or even that it is an extraterrestrial microscopic lifeform like diatoms.
Inventors from the 1900's would even freak out and call them magic.
Inventors and Engineers in 2024 freak out and call capacitors black magic.
And even if you could explain it to them, and they completely understood, they still wouldn’t be able to duplicate it in their lifetimes. It would take generations to reproduce the material and manufacturing technologies behind it.
It's incredible that, with silicon, we can make MEMS (microelectronic mechanical devices) to do almost any measurement. Accelerometers, gyroscopes, thermometers, microphones, and so on.
That gyroscopes, normally, rotating flywheels, can be made from silicon microchips is, to me, truly amazing. Silicon gyroscopes don't rotate but vibrate instead.
Silicon gyroscopes look more like they act more as sensors than flywheels to store inertia.
Technically I think thermometers aren't MEMS, just thermistors. (Ie basically a lump of something that changes resistance with temperature, no moving parts)

What a surprise, it like like every other microphone in a compact electronic device
When I got my first pair of Airpod's Pro I was astonished by the transparency mode, how they had microphones that would allow you to hear your surroundings with perfect clarity. The ability of the tiny bud to create 3d audio with no latency.
They even have a mode now where they will turn down your music if they detect that someone is trying to talk to you.
Amazing tech.
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

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.
Lovely to see this finally, I find myself equally interested in how the sound doesn't interfere with the microphone
No matter how beautiful machine you invent, the moment it's invented, the value of it starts decreasing right after
that is the point...you don't want to be your invention stuck in the shadow, it was good for a short profit but you wanted it to grow and reach everyone so one day people will look into it and your name on it.
Except nuclear weapons
Monetary value isn't value
It has no value before it's invented, so what's your point? You wanna keep inventions that could shape the future of humanity to yourself? The fact that as it becomes more broadly available it also becomes cheaper has infinitely more value for everyone as a whole than anything else.
The value doesn't decrease, it probably increases. The material cost of manufacture goes down, which makes it more accessible.

We need to appreciate how fortunate we are. The research to make this did not cost $10
Y'know what's funny to think about...miniaturization doesn't just benefit the consumer, it benefits the company as well. Less materials used to manufacture something which means lower cost to them, and lower weight saves on transportation costs, which are a significant fraction of the end user cost for any item.
The only thing I can think of is how many of those are planted everywhere and how easy it would be to do so.
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.

@@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.

Fun fact: all microphones are speakers, and all speakers are microphones, IIRC. They work horribly, but if you can push enough energy through the membrane of a speaker, its movement will apply signal to the wires, just like a microphone.
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.

Is the top layer deposited on the stationary layer after the hole are etched? Or is the whole thing manufactured the other way around and glued shut, since then you could do the ion etching for the cavity beneath?
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.
This is exactly what the internet is TRULY for.

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.
