Hi guys!
Am not sure whether this is the right place to post this though this does seems to be the most appropriate area...well, here goes:

Rather curious actually: in speakers the cones, tweeters produce the sounds but what is it in a headphone that gives the fairly wide range of frequencies?
Recently read about the electrostatic speakers: can anyone kindly enlighten me in simple language how they work?
Is that the same principle as that in the headphone?

Thanks!

Headphones use drivers of the same sort as regular speakers. But since they are right next to your ear, you don't need a large driver to move a lot of air to create bass. A small driver will suffice just fine because it's right there next to your ear canal, aiming right down there, wheras a woofer in a regular speaker has to pressurize pretty much the whole room, and only part of the bass wave is getting in your ears. So a much smaller driver can crank out MORE than enough bass to damage your hearing, and is thus small enough to be able to handle the fast speeds necessary of high frequencies that would not be handled by a woofer in a regular speaker.

And electrostatics use um.... guh.... yeah... I'll let someone else answer that one better
