As someone who works with speakers for a living, I'd like to give everyone a friendly fore-warning. This is a cool parlor trick to move air - - but it's not good for your iPhone's speaker (or really any loudspeaker for that matter). When a speaker's surround excursion gets broad to move air like this, it is put under a great deal of stress. Over time, the surround will weaken and rattles will develop. Distortions will grow and in many old iPhones ....you'll notice that the speakers can sound "crackily". Apple and the other manufacturers work hard to develop tiny speakers that produce a full frequency response inside of your phone. I really rely on it and use it a lot. And for the cost of an advanced phone these days - - I'd rather take care of it so that it lasts as long as possible! Addendum: playing the speaker at fixed low frequencies and high volume for periods of time will also heat up the surface mount audio amplifier, reducing not only it's life but also the nearby components on the board (and who knows what that part may be in a crammed iPhone)

[@psirvent8]

I agree 100% as this very app did indeed damage the speaker of my iPhone 3GS many years ago by now. It ended up sounding off or "untuned" so to speak.

You literally finally gave me the answer to how sub-woofers create so much air when you listen to music loud, while they in fact just vibrate so the sum of air moved is zero. Now I know... it's just because when it pushes out it's coherent, but when it sucks in, it's not :)

[@Splarkszter]

physics bro

[@Megaphonix]

Also, lower frequencies have longer wavelengths - he showed this with the sine wave generator, as he lowered the frequency the wavelength increased which resulted in the candle being blown out. So while low frequencies still have compressions and rarefactions, the wavelength can get so long that each of those phases can encircle an object such as a candle flame.

[@GetMoGaming]

I think that would only work if you're in front of the port (hole). I don't think it would work if you are in front of (or behind) the subwoofer cone because it's not a concerntrated flow there.

[@dragonapostle]

Just go to a bass competition. They shatter windows. You learn a lot about this stuff while building boxes. You need the air space for the speaker to match the air for the proper frequency the speaker is rated for. Having the right box for the subs is essential to get the proper sound. There are systems out there that can blow a candle out from outside the car easily. Not mine.. but I know a guy who is on his third windshield created by the force of his subs. It's amazing!

Thanks for this. Nicely explained. I'd like to suggest using smoke from an incense stick or the like, instead of the flame, for exploring the flow patterns. Less risky and I think with a longer-affected column. On a somewhat tangential note, I think an incense stick or the like could be used to measure the airflow in a room.

This is unfortunately hard to do in a restaurant, but meeting rooms, classrooms, etc., it can help.

You can demo sound just being air blown about really well with subwoofers in a car. The subwoofers will be separate in an enclosure in the boot/trunk but still easily flap the air around Inside the car.

Moving the stereo balance left to right had loud sound on either left or right but no sound when it was both. Luckily my dad realised what it was as soon as I explained it, they were going out of phase I think they call it?

Actually sound can make particles travel really long distances. If you've been to a concert standing in front of a subwoofer, it goes as deep as 30Hz. The wavelength that a particle travels at 30Hz is 10,37 metres. At a sustained bass guitar note, the subharmonics behave as an industrial fan.

Wouldn't the amplitude (volume) of the wave be relevant to how far a particle travels rather than frequency

[@skk6811]

@@shahnawazhaque7243 A particle does not really travel anywhere, it just vibrates back and forth and this distance is called wavelength. And wavelength (λ) is directly related to frequency (λ=c/f) where c (speed of sound) which we assume is constant 331m/s. Amplitude is just how far the membrane pushes the air but it won't make the particles travel further, just more mess is being moved. But I'm not sure with the amplitude part, it's probably more complicated than that :)

@@ronal8824 oh, I see. But the thing is you can’t replicate a snow globe yourself without the proper materials and knowledge. But this? All I had to do was download a free app that is used to produce different frequencies (and the app was used in the video, btw), set it to a relatively low frequency, and that’s it. I had air flowing out of my phone’s speakers completely for free! Not to mention I have more customizability with this app too. So why would you pay a single dollar for an app that just takes the free app, limits it, then brands it?

@@xXmlgamingXx355 I think "an app to play different frequencies" would count as "proper materials" and "knowing the frequency" would fall under "knowledge".

[@damienlobb85]

I noticed this some years ago with my Galaxy S6. I was listening to an audio book and I felt the air on my hand. I wonder how good this is for the speaker to be constantly at it's limit on a set frequency (They drive these things quite hard to reach the volumes they reach at this size). There are smart amps that are designed to protect the speaker while using every bit of excursion, but things can fail, just like OCing your CPU etc.

[@whong09]

It's great to see content on this channel that shows how physics in the real world works. Basic high school physics will tell you that sound doesn't move air but real physics isn't about frictionless, idealized models behaving in a vacuum.

We could preinstall big speaker systems generating the right frequency in areas where fire/smoke is detected, effectively replacing sprinklers or adding to them.

[@Grizzly_Lab]

Well, you remembered me a VHF Handheld Marine Radio I had, that had a function called "AquaQuake": given it was waterproof (ip67) but still it was possible to have some water stuck on the grid, by activation this function, the speaker would have emitted a low-frequency hi-volume tone, vibrating vigorously, to help getting rid of the water on the grid. I understand this function is also present to a lot of similar handheld marine VHF radios Very interesting, anyway

Also in smart watches my Samsung watch emits sound after I turn off swim settings and it shoots the water out.

I mean it makes sense, sound is just the variation in air pressure waves, which have a measurable frequency. Frequency determines pitch and so on and so forth. So my theory would be that it uses sound to blow out the candle. Or at least that was my thought when I read the title of the video, anyways.

[@user-jj8cp9go6m]

my phone already does this; when my volume is up, some air leaves the speaker, the reason why i'm keeping this phone is that despite it being slow and bad, is that the air-producing speaker makes people shouting at me in phone calls very realistic

[@juanes8931]

Why are they shouting at you

[@juanes8931]

Buddy you ok

[@JustAPakistaniGamer]

high frequency sound from the sound port... app configured to phone model to present UI "Blower" element where the speaker grills sit in each particular phone model (i'm assuming) Quite interesting... alhtough this would play hell with the speaker tho... might even break it or cause problems with extended use of the app.

[@courtneyhudson9368]

that's the same thing I'm thinking it might damage your phone speakers after using a long while cause the phone developers never let us use our speaker like that

[@AdamBragg]

Very interesting. My personal question now is, why do the rules of physics state that sucking and blowing act differently? Why does blown air move in a coherent tube? Why doesn't air move the same way whether it's being blown or sucked? No doubt there is a reason, but I do wonder what that reason is.

[@TheActionLab]

because of the direction of flow compared to the shape of the tube. In sucking the tube that makes the air coherent comes after, in blowing the tube that makes the air coherent is before.

Xiaomi has something that is used to clean the speaker of the phone. That is by using an high volume sound in some hight range. Very noisy, but it actually blows air. A speaker can blow air because it vibrates when it sounds. Funny. And I have only seen 0:29 seconds of the video BTW
