Below, a photo of a hand-held speaker near a computer.  The image is an attempt to add visual interest to the article...

Hand-held speaker?

I don't think so. Looks like a JBL style (2402-ish) ring radiator supertweeter to me, the version that mounts externally on a larger speaker system to extend the HF response to dog-whistle territory. Mot exactly what you'd carry around to use with your laptop.

The linked article reminds me of a book I read in around 1968 about a kid--Henry Huggins maybe--who's father was a high tech scientist.  He (the son) had access to the computer his father had in his house and he and the girl next door decided how much of a timesaver it would be to program the computer to do his homework.  The conclusion he reached by the end of the book was that it was WAAYYY more work to program the computer than to just do the homework.

That seems like an amazingly impractical route to exploit a device.

The one solid example they gave was, if an app already uses the accelerometer to "do something". But... some other nearby device would have to know that someone was doing that on their phone, and precisely when to generate the sound. OK.

I can see how you could manipulate an accelerometer and decode that as data to then execute a function. But that would tend to presume that the device would have to be exploited already, because some sort of software would have to already be on it to decode that data, and then do the malicious activity.

It is a "hand-held speaker" in the sense that, in the picture a hand is holding it.

Notice the "PYR......" name on the base. I don't recognize it, but that sounds like the brand name for a pseudo high tech computer accessory. It's probably made mostly of plastic and costs $19.99 and probably has "high resolution audio" in its marketing literature.

Ha !! Yes, reminds me of the fake the moon landing conspiracy theory...

Harder to fake than to actually just go to the moon...

You would think if we went to the moon "that" long ago, (I believe we did) we would have a moon base by now and some on their way to Mars. Why did the momentum crawl to a stop and "other" technology flourish?
Back then, we were in a race with Russia as our competition, Perhaps we need competition as a stimulant for progress? NASA projects used to be such a turn on for me.
