How do speakers displace air?

I just really want to know what goes on inside a speaker. because i dont understand how my subwoofer can pump so much air out of it without using a fan



anyone know?

lmao, yea i always kinda wondered this too



i wonder what google has on this

lol i had a look on google but i couldnt find anyting that really answered jmy question

weird,



anyone else?

well it is kinda like a big air pusher. it moves back and forth. so it pushes the air when it gets power and a electro magnet pushes the cone out. thus pushing air. which goes to you and your ears and you ears are the same thing. it can feel the presure change and makes noise. no noise is technaly air presure. even slight sounds still have this presure but you cant feel it. watch mythbusters on the subwoofer. they have a good what it is, i will see if it is on youtube.

lol do you mean that the movement of the speakers creates the air flow?

It doesn't create air, it simply changes pressure and forces it.

The internal workings of speakers are very basic. It's nothing more than a magnet connected to a cone of some sort. As the magnet gets power, it pushes the cone creating sound waves.

Hah, if you're really curious, look for a junkyard or something and try to get some old speakers to rip apart

i kind of understand now

thanks

i think i get it,,



but i still dont get how subs can push so much air lol

because they are big and also because they are ran by a lot of power; they can "vibrate" quickly.

another thing is that all the air they are pushing is exiting through small holes.
if you were to build a box with a hole in it, them put a plunger in the back, you'd be able to push the same amount of air as a sub does in one stroke.
