References? They'd be useful in assessing how much of a risk this really is. Also we don't have a hardware switch for the microphone yet, so an attacker could just use that directly.
I suspect there are some specific hardware requirements to use a speaker as a microphone, so you'd need to check whether it's an actual risk in this case.
Accels have been used as a side channel for touchscreen inference, so using gyros and magnetometers as a side channel is plausible:
