I'm a bit confused about the relationship between the motion of the speaker cone and the waveform's shape. It's easy to think that the speaker moves in and out in direct relation to the voltage level applied and that if the signal is clipped that the cone moves out, stops for a while and then moves back in, stops for a while etc. Question is, is that REALLY what's happening? OR since the signal voltage level represents the AIR pressure on a transducer(microphone) the speaker really has to move much differently to recreate the sound. If for instance a square wave or close to a square wave is fed into a microphone the diaphram is not pressed back for a certain length of time and then snapped back the other direction for a certain lenght of time to represent that sort of a wave form. It is instead pushed back at the speed of sound at the top and the bottom of the wave and the electrical result is that the voltage swing between the two is what produces the "square wave" at the speaker. In other words, it tries to rareafy the air in one direction at the speed of sound and then compress it in the other all to produce our square wave that was input from the microphone, is this correct? AND is it why amp clipping is much more detrimental to speaker life than other things????
