- 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
Analog technology, physics does there figuring out.
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.
It truly seems unreal!
Very impressive. the phone speakers are so small yet quite clear.
Human engineering just amazes me.
Which other species performs engineering lol??
So what planet are you from ?

You are one of the few channel that amazed me... Well being an engineer and a curiosity to know drives us always and we tend to imagine what may be happening you guys made it real... Thank you ...👍👍👍
Thank you so much!
Beautifuly animated,
Clearly explained,
Nicely delivered.
I just subed..
Thanks a ton!
This is by far the most amazing channel on YT in it genre. How doesn't this have million + subs?
Great animation and explanation, looking forward to see more from you 😍👌
Came here from LE
i am amazed to see , this Detailed explained video
thank you for amazing quality informative video
Thanks!
Great video, I've wondered how speakers worked since I was a kid and this is one of the best explanations I've seen! Proud to have been one of the first 1000 subscribers, excited to see what's in the future for this channel
Thank you! That's a nice compliment!
Here's a question: How does a speaker generate 2 sound simultaneously
You should check out the followup video that goes into what is sound? : th-cam.com/video/24yESm63tSY/w-d-xo.html
It is one sound. Two sounds fused together in one.
Radu Burcea with multiple audio channels, like stereo. Some smartphones use the earpiece speaker with the loudspeaker to make two sounds at once, which is stereo.
@@dusscode YOU ARE WRONG. PHONE SPEAKERS ARE ALWAYS AND ONLY IN MONO. Have a nice day!
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.
Your voice is also coming from the speakers of my phone
So what is the miracle?
Same question 🤔

Amazing! Great animation and explanations, its clear and very understandable.
Found this channel and I am impressed, how good the information and the explanetion is, I hope this get's what it deserves, because this is gold here.
Congratulations to the creators.

Rip TH-cam compression
Really. Learned my lesson to not do full-screen particle simulations.
Branch Education it was a sick simulation though 👍🏻👍🏻👍🏻
It's the best i ever seen to expand something or subject. You're the best
The level of details is just incredible!
Man, I love your videos. I just stumbled upon them, and I must say - I'm impressed ! I've learned quite a bit thanks to you, cheers! keep up the good work!
One of the best channels on TH-cam! Wow I greatly appreciate every bit!
Lovely info. Thanks
Thanks for your sharing!
Great work. Very well explained
Amazing video, thank you
Subscribed! Fantastic quality!
So neatly explained !!!!
thanks man for such a amazing knowledge
Great breakdown thanks
Thank you very much, keep on track!
Amazing explanation....thank you 😊
Thank you so much..much needed explanation
You are amazing ! Thanks for this knowledge !!
I really like your Hard work on making this animation
I am very excited learning this. Thank you very much :)
Just awesome explanation
wow! dude that animation that voice, that explanation, Just where have you been all these years?
I can't get enough of this channel!
I am so amazed by the details this channel provide alongside the animations that I'm bunge watching the vids
Is this the best channel on TH-cam!? VERY happy I stumbled across this channel. Thank you!
superb explanation.
Fab information, thanks! Excellent content 👍🏻
Amazing video, excellent explanation. Well done
Always wondered how this exactly worked, always got a vague explanation now i know im detail exactly how it works. Thanks
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
Very nice explanation Sir..
your 3D presentation really amazed me, keep it up!
Thanks!! Glad you liked it.
Very excellent education.
These videos are amazing. Thankyou
this channel is a gold mine.
wow, explanations are really good to want to keep going on.
A very informative video.
I hope many content creators will follow this path and show the marvels of everyday objects and gadgets around us.
great concept
I press like even before watching the video, because of your detailed description and attribution.
*Magnetic Field Looks Satisfying.*
*Thanks a lot.*
amazingly explained
Amazing content!
Brilliant piece of work... Very very well explained.. Hats off to your effort... All the best for your future videos :)
Amazing content, thank you
Your videos are excellent !
What underrated simplicity of technology. Great video.
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.
Good niche on the micro speakers, great animations, I understood your explanations thanks.
Wow man ,u r so good in explanation of things within 5 minutes
Learning a lot from this series. Great job on the exploded views.
Mesmirizing.Excellent Designing.Please provide more about the Smartphone parts in details like this.It is really informative.
Your animation is the best👏👏👏
Awesome... simply awesome.
I've always wondered how speakers worked. You are an absolute legend!
Again.. you did a great job 👍👍👍❤❤
Thanks for sharing 🙏🙏🙏🙏
1:15 I didn't see the spider until he labeled it.. It was an awesome video...
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.
Very nice teaching sir
I am glad I found your channel. ❤
Mind blowing animation.... Impressive videos... Keep up with your work.. Make more videos.
Amazing video😍😍💜💜
Great video !!!
Thanks!!
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.
Nice ....plz put more videos
I love your work!!!!! :)
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😊😊😊
Great ... make more education videos like this ..
thanks for this
No problem!
that's crazy good video
Great content. Subbed.
Very good video sir
thank for this video,, that was really well done and helped a lot
Thanks!! Glad you liked it.
Amazingly explained
Plz sir next video on led and oled plz plz sir
The touchscreen episode gets into some of the OLED, an upcoming ep I'm working on will go into detail of how one LED works.
Beautiful
Thank you
great videos...that helps too much....thank you...
Glad you liked it!
Nice work
Plz make a video how small connectors, smd and components work and how they are made
Best channel i have ever found
Awesome! 🎧🎶😎
Vídeo incrível!!!
Great.. Keep continue
Thanks
Fantastic
Nice one
Great keep it up
Thank you .
You amazed me with your content, auto subscribe 👍
