What is current and voltage of audio signals?

I dont get it. A (raw, without any extra components) speaker is more similar to an inductor than resistor or capacitor. If a speaker was a resistor then I get it, but I doesn't the induction of the speaker have to be "compensated". Using a current-waveform instead of a voltage-waveform makes more sense to me. I can rephrase the question a little: Say that I want to mimic the waveform seen in Audacity of a specific wav-file. Now, is it more important that the volt-curve of the output to the speaker or the current-curve matches data seen? Especially considering + and - parts of the seen signal

- Audio signals are AC (alternating current) electrical signals. They are typically measured as AC voltages or as decibels relative to voltage (dBu or dBV). ... Microphones are said to produce audio signals at mic level. Mic levels are nominally between 1 millivolt (−60 dBV) and 100 millivolts (−20 dBV).
