How Speakers Make Sound

Just one speaker can reproduce an entire orchestra of sounds. How is this possible? The design is deceptively simple, with incredibly complex potential.

At render time, I had an issue I didn't catch until the video had a lot of views (so I can't replace it easily): the voice coil is off center. It should sit centered with the magnet top plate and pole piece, as shown in this diagram from Wikipedia: upload.wikimedia.org/wikipedia/commons/c/cd/Speaker-cross-section.svg

When you study technology, you realize how miraculous it is, and how the average person wouldn't know where to begin to reacquire it if they ever lost the technology they take for granted every day.

[@vladimir_ckau]

It's even more so nowadays. In 2000-2009 I and some of my friends were totally obsessed with the technology and the future - as many was before us too. Heck, the sense of coming up hi-technology era was all over the place, hense the cyberpunk genre, industrial music, all the subcultures and different forms of art that happened in awe to whats coming. My friend weared small CPU from a cell phone as an earing, lol. Looking back, it feels like the Lovecraftian's novel - people praying old god to awaken. We were so out of our minds for the future... and then future happened. Intraweb's Cthulthu stepped out of the ocean, and devoured us all. Sadly, the "new" god has really bad taste. Dickpics, SJW and multi-genders, Tik-tok, Belle Delphine, iPhone, and all-seeing eye of Facebook and Google... Who'd know that the face of the future is a Tyler1, and sound of the future is a hyena-laugh. If humanity somehow loses technology - that's gonna be basically death of majority of people, due to an end of lifeless egocentric communities, with all them beauty-bloggers, cam-models and twitter-warriors, not even speaking about basement-dwellers with their Call Of Duty all over your mother. It's just traumatizing, to realise how deep in worthless and useless shit is a mind of average normal person. How far it is from divinity of life and reality itself, that only can be grasped slightly by knowledge, understanding of things, empathy and attention to details of every thing and every minute in life of self and others.

[@baitman2368]

@@vladimir_ckau Would you mind recommend me some books to learn more and acquire REAL knowledge? Thank you.

[@therealkwesi]

I was literally thinking the same exact thing while watching the video and it's crazy I scroll down and see a comment about it

[@davidb5205]

Why the pessimism here? First, plenty of people study engineering precisely to design, test, and make devices like this. It's not uncommon; these comments exaggerate. A surface-level KZbin video won't make you that much more knowledgable than the average person. Second, in our modern world, it's impossible to have years worth of highly specialized knowledge in everything (medicine, engineering, food supply, transportation, etc). Since when is it necessary to know how everything works in order to appreciate it?

[@vladimir_ckau]

@@davidb5205 Since consumerism. Yes, knowing how things work is not quite necessary to appreciate them. No, modern men aren't capable of doing that, until they are exposed to the beauty of "how it works" and "complex while simple" overview. Beauty is in the eye of the beholder. Not in the ONE book to read them all that previous bloke asked about (lmao!), and not in the surface-level YT videos.

THIS MAKES SO MUCH SENSE. That’s why a single speaker is able to create a symphony - it just combines the sound of every instrument’s frequency into one. Now it makes sense why multi-speaker setups increase the quality of the sound. Different frequencies can be divided amongst the speakers, allowing for a higher range in each speaker. Awesome explanation!

[@iggysixx]

+ it's why a vinyl record can reproduce a full range of sounds from a single point (the tip of the needle) ... And why digital audio cables can transmit sound through pulses of light alone.. :) Oh, and it's why 'phase' matters. If 2 soundwaves are identical, but exactly out of sync, the result is silence (because the sum of +1 and -1 equals zero)... And if they are IN sync... The result is twice as loud

[@alexism1635]

Multispeaker setups increase the quality of the sound more because they can introduce delay to provide a sense of depth and space. That is why mono vs stereo exists and multichannel audio sounds so much better. This is boosting the quality more than being able to divide up the frequencies.

[@ULV_OrthodoxRabbi]

I still can’t get how amazing speakers are into my head, to mimic such a vast amount of sounds so perfectly. As far as I’m concerned, it’s magic.

[@veronxoros5387]

I am always amazed by how speakers are able to produce such range of sounds, by using a single diaphragm, and many of them together such as in music or songs!!!

[@jesusvera7941]

the same thing amazes me so much too

[@Enitoni2]

It's simple actually, if you consider the fact that your ears also just receive very complex vibrations. Waves can be summed together into a single wave, and this actually happens in real life when your ears pick up several sources of sound in your environment, those waves interfere with each other before reaching your ear. All sound waves can also be deconstructed into sine waves, which is the most pure form of sound (or signal!), a perfectly clean vibration. In reality, sound waves are just a bunch of sine waves summed together at different amplitudes and frequencies, if you look at it that way. I recommend learning about fourier transform which is how you can measure frequencies from a single wave on a spectrum, it might help you understand how it all works together.

[@ninemilliondollars]

@@Enitoni2 What's also cool is how your brain can separate various sounds and enable determining what they are. Many years ago I was taught Morse Code in the military and had to listen to hours of transmissions and transcribe them. One training course was about being able to identify the Morse Code sound while "jamming" sounds, like quickly changing high pitch-to-low pitch frequencies were overlaid on it to make it very difficult to detect.

[@wadimek116]

Well they cant unless you are using headphones. There is no option that one speaker will reproduce whole frequency range. Two is hard three is optimal

[@googleaccount-mv7zk]

Then combine it with video

3:40 but the true story is when speaker cone moves back and forth it not only creates positive air pressures front of the cone but also negative pressure back of the cone both cancel it out at some degree that makes sound lower but if you enclosed the speaker from one side , one sided wave can't Scape into the air but compressed inside enclosure and bounce back as positive wave , both positive wave combination makes sound louder that's why speaker needs , speaker box 😎
