Hello,
I'm trying to understand how speakers work. After reading on the net and dissecting a bunch of speakers, I still don't get it ...
1) Lets say I pass a square wave of a certain frequency through my speakers. i imagine that this will cause cause the speaker to oscillate between its two states (up or down) depending on whether the signal is low or high. Is this correct?
2) What makes me think that (1) is not quite right is that most sounds are made from sine waves - pure and harmonics. How can the speaker be binary in the face of a sine wave? Is it the case that the up and down of a speaker's diaphagram happen at the peak and trough of a sine wave?
Thanks for your help!
