How do speakers work? Incredibly small, yet impressively loud
Ғылым және технология
Speakers weigh less than a dime but can be heard throughout a massive room. How do they make such intricate sounds while being so small? This fundamental lesson gets into the components of a smartphone's speaker as well as their function.

What amazes me is how people figured out which amount of current produces which sound... The fact that that little piece of material moving back and forth can create such intricate sounds is mind blowing

woah i was literally wondering on what factor did the current changing depend on as i was watching this. truly fascinating

They didn't have to. A microphone is the exact opposite of a speaker. It has a thin metal plate that vibrates when sound hits it. That plate then moves an electromagnetic field to make pulses of electrical current. The current is sent to a speaker (which as the video showed) vibrates at the same frequency producing sound. The only difference is the speaker is electrically amplified to make the sound loud enough to hear.

Exactly. It also sounds far less marvellous when you realise that sound is literally just a longitudinal wave made by an object vibrating. Electromagnetic induction had also been known for quite a while, so it was only a matter of time before someone linked them together.

Very impressive. the phone speakers are so small yet quite clear. Human engineering just amazes me.

I press like even before watching the video, because of your detailed description and attribution.
Always wondered how this exactly worked, always got a vague explanation now i know im detail exactly how it works. Thanks
I am very excited learning this. Thank you very much :)
I can't get enough of this channel!
thanks man for such a amazing knowledge
Thank you very much, keep on track!
Amazing video, i just have one thing to say, this type of informative animations has its own audience who are really looking to dive into the details and the backbone science supporting it, so take your time to make it even longer because we love it, thanks great effort!

Thanks for the input! Most of my videos are clocking in at 10 min. This speaker one just happened to be a bit shorter.
I am so amazed by the details this channel provide alongside the animations that I'm bunge watching the vids
Mesmirizing.Excellent Designing.Please provide more about the Smartphone parts in details like this.It is really informative.
You are amazing ! Thanks for this knowledge !!
I really like your Hard work on making this animation
wow, explanations are really good to want to keep going on.
wow! dude that animation that voice, that explanation, Just where have you been all these years?
Learning a lot from this series. Great job on the exploded views.
Great work. Very well explained
What underrated simplicity of technology. Great video.
Amazing explanation....thank you 😊
It's amazing technique to understand .... And its too much help full as electronic engineering.... request to mack more video and cover more topics.. and...keep it up😊😊😊
So neatly explained !!!!
Good niche on the micro speakers, great animations, I understood your explanations thanks.
Subscribed! Fantastic quality!
Fab information, thanks! Excellent content 👍🏻
*Magnetic Field Looks Satisfying.* *Thanks a lot.*
I always wondered how speakers worked since I was young. It always blew my mind how our phones can transfer exactly what our voices sound like. Like what tiny instrument inside this small phone can possibly mimic my voice so perfectly? Thankyou for these videos.
Amazing video, excellent explanation. Well done
Wow man ,u r so good in explanation of things within 5 minutes
your channel is freakin amazing. if you end up seeing this thank you for making all the content you have. I have learned so much from this channel.
Here's a question: How does a speaker generate 2 sound simultaneously

The frequencies must be combining to come out together as a combined wave(two frequencies can merge in interesting ways) , both having low amplitude or "volume" per say, individually.
Thanks for your sharing!
These videos are amazing. Thankyou
Amazing video, thank you
Thank you so much..much needed explanation
Mind blowing animation.... Impressive videos... Keep up with your work.. Make more videos.
Great breakdown thanks

Very nice explanation Sir..
I am glad I found your channel. ❤
Dude sorry Bro..... Ive locked in riddle to understand how the sound is generated in Speakers For almost 5 years today I've got it Through your teaching . . Am heartily thanking you for your generous work of sharing and teaching
Nice work Plz make a video how small connectors, smd and components work and how they are made
Your videos are excellent !
