There is also 'proof' that the functionality can be abused: badBIOS used the built-in PC speakers as a form of high-frequency modem-this despite the fact that one would expect PC speakers to be wired only for output.

This doesn't address the software question, but mechanically, a speaker can function as a microphone. 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). So yes, a speaker can pick up vibrations (albeit sub-optimally), and a microphone can emit vibrations (albeit sub-optimally). If you think about the original phonographs, the same component was used to record and listen to sound.

The difference is what is labelled as input. In other words, both have an electrical signal on one side, and vibrations on the other. Microphones can be thought of as speakers in reverseД«oth incorporate circuitry able to translate vibrations into electricity (or vice versa).

The processes are opposite (one takes electrical signals as input, and outputs air vibrations, one takes vibrations in the air and transforms them into electrical impulses).Д«oth mics and speakers (or headphones) have a diaphragm, and as mentioned in the Wikipedia article: One simple experiment you can run is to plug your headphones into a microphone input and speak into them.ДЇundamentally, both emitting sound and capturing sound is about dealing with vibrations in the air. Are speakers that sensitive?Д¬an software be used to operate an average consumer speaker as a microphone? While an audio chip being a generic converter makes sense, I don't see how an average speaker can convert incoming audio into useful signal. I can't tell if Garret is being serious here. Telling them to disconnect the internal speakers as well.
