i used to think a speaker cone moves like the waveform of the voltage being applied to the coil, ie high positive or negative voltage = speaker cone inwards or outwards.

i realised this is wrong... the voltage applied to the coil is proportional to the force being applied to the speaker cone, not the cone's position. the cone moves in the derivative function of the voltage waveform applied to the coil, ie high positive or negative voltage = high positive or negative movement of speaker cone

then i realised this is wrong too. the voltage applied to the coil is proportional to the force being applied to the speaker cone, which is proportional to the _acceleration_ of the speaker cone. the cone moves in the double derivative function of the voltage waveform applied to the coil, ie high positive or negative voltage = high positive or negative acceleration of speaker cone
