Time to disable the mic  

thankfully there's no mic on this pc.

There's a Mic on the Phone next to you

Quote: both mics and speakers(/headphones) have a diaphragm, and as mentioned in the Wikipedia article:

Microphones can be thought of as speakers in reverse

both incorporate circuitry able to translate vibrations into electricity (or vice versa). In other words, both have an electrical signal on one side, and vibrations on the other. The difference is what is labelled as input.

if you think about the original phonographs, the same component was used to record and listen to sound.

So yes, a speaker can pick up vibrations (albeit sub-optimally), and a microphone can emit vibrations (albeit sub-optimally).

Many TV speakers are actually speaker arrays, too, so that you (sort of) have an array of tuned inputs (important because it might allow using post-processing to enhance the wanted audio).

This doesn't address the software question, but mechanically, a speaker can function as a microphone.

There would have to be software involved, it's probably something the NSA already has, if they want to listen to someone through speakers they'll slip it in via a Windows exploit.
