Battery is not AC, though, audio circuits are AC. Even in a DC circuit electrons travel extreme slowly, one meter per hour. So even in DC circuit its not correct to say they're "flowing."
Thus, in audio circuits (AC) electrons just wiggle back and forth on both wires + and - at the instantaneous audio frequency, frequency range nominal 20 - 20k Hz. And the audio source produces the audio waveform and it's the *combination of two wires* + and - that produces the acoustic audio waveform via the speakers. To top it all off, as I calculated on one of these threads about a month ago, electrons move only about one millionth of an inch at a time during their rapid wiggle dance. Furthermore, free electron along each wire + and - net movement is zero.
Finally!!
Now tell me again how the electrons carry the signal in the wire...
