Microphone in your Earbud is Amazing Technology

What does the microphone inside of an earbud look like? It's a surprisingly cool bit of technology!

As someone who works in the micro/nano scale industry (semiconductor) it’s always insane looking at the products and remembering how insanely small things we use on a day to day basis are

[gymkhanadog]

And what's even more impressive is that the cost on that component is like $0.01

[DonariaRegia]

Micro-technology is impressive, affordable micro-technology is an almost unbelievable achievement.

It would amazing to see engineers and inventors from the past react to modern tech. I'm sure they would love it.

[robinbm]

i can't wrap my head around how many cool engineering marvels are crammed inside of a smartphone these days

[CLCasual]

I think the fact these things cost less than a penny to manufacture, package and transport should be considered a marvel of humanity

[koolerpure]

It might be me over thinking the whole process but the idea of that working like it does blows my mind. Voice converted to digital then sent through a web of networks just to get reconverted to sound and be the same audio as the original

[Rena]

Not sure if to feel amazed by the complexity and detail of such a component or to be scared on how small and concealable it is

[BandwidthMusic]

Finally, a microphone that is actually micro

[dacobus]

What amazes me is getting precision holes that small

Please never stop making these kind of videos, its pure gold for Engineering Students like me ❤🎉🎉🎉

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

[Daniel.Belas]

Damn they really can bug your home without you knowing

[ShaneCosgrove]

We take mics and speakers for granted. To reproduce complex sounds so well is mind blowing

[makarovx]

These are the kinda shorts I wanna see. Really neat, high quality, informative content. Absolutely magnificent 👌

[Delheoblanc]

amazing short! more of these small components!!

[CiaoBello]

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

[Maninawig]

I still find the depth of sound these get to be remarkable. I mean, it's just a wobble, but you still hear voices, complex sounds, and everything so clearly destinct.

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.

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.
