How do speakers work? Incredibly small, yet impressively loud

[@gibbethoskins8621]

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

[@vandermonke4178]

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

[@rylanthompson5844]

Analog technology, physics does there figuring out.

[@DoomFinger511]

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.

[@Leanzazzy]

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.

[@bluelotus.society]

It truly seems unreal!

Here's a question: How does a speaker generate 2 sound simultaneously

[@BranchEducation]

You should check out the followup video that goes into what is sound? : kzbin.info/www/bejne/aGXcdoaja5inibs

[@marios9992]

It is one sound. Two sounds fused together in one.

[@dusscode]

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.

[@osiandelzongle6738]

@@dusscode YOU ARE WRONG. PHONE SPEAKERS ARE ALWAYS AND ONLY IN MONO. Have a nice day!

[@anonnona6940]

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.

[@saikatazad5631]

this channel is a gold mine.

[@sriguru455]

As the diaphragm moves, it moves the air particles around it thus creating sound waves which is perceived as sound. My question is, the same can be done with hands, right? how doesn't moving my hand alike the diaphragm creates a similar affect?

[@Cyberbully34]

I've always wondered how speakers worked. You are an absolute legend!

[@Daniel-ru3dq]

After this amazing explanation, I still wonder what are the main differences between an expensive speaker from brands like (JBL, Bose, Denning, Altec Lansing, Burmester) and other brands. Is it just the construction and quality of parts used considering all other parameters equal? Also what exactly is meant by sound stage and sound equalisation. Are they two different concepts?

[@BranchEducation]

Hey Daniel, to be honest, I don't know the differences, just a basic understanding of the components and their function. As for a sound stage vs equalization, they are indeed different. One is a space for film making, and the other is where you adjust the frequency levels to get something that sounds nicer.

[@clarencegreen3071]

The major difference is that of scale: where the speaker in a phone probably produces less than one watt of sound energy, a large speaker that's part of a stereo system may dissipate hundreds of watts and produce sound that will rattle your guts. To handle the greater power, everything about the speaker must be scaled up. The magnet may weigh several pounds, and the voice coil must be wound out of large wire, which may be surrounded by a ferro-fluid to help keep it cool. And, the speaker cone and even the frame of the speaker must be carefully designed. All of this adds to the price - a good speaker is not cheap!

[@omsingharjit]

Lots of Q How Battery work's there's lots of video about that on the web but but no one has explained at atomic level , like * what properties of material needed for making battery ? * which types of material can be use for anode and which for cathode ? * What is responsible for cell nominal voltage ? ( Ex , why li ion generate 3.6 to 3.8 volte and why lead acid only generate 2 volts so on )? *How and why some type of separator only allow to pass ions ( which is big in size compare to electrons ) but can block electrons which is much smaller ? And question for Proton exchange membrane ? *Is there any maximum limite for cell Nominal max voltage ? Or it can go higher in future from 4 volt to higher like 5v or 6v .. ? Ply you flash light these questions in batteries video ??

I have some questions. 1.How the electric current wave is produced corresponding to sound? 2.How one dimensional motion of diaphragm produce such complex sound? I mean by this motion, only frequency and amplitude can be controlled but what about sound quality/timbre and smoothness of sound?

[@BranchEducation]

Yeah! These are great questions. The current in the coil is produced by a digital to analog converter [DAC], which will definitely be an episode eventually. For your second question, ya should take a look at the other video ' what is sound'. The smoothness relates to the sampling of the audio and the DAC- sampling will definitely also be a video.
