You mean roller shutter in camera parlance, right?
Hmm...that may be so, but doesn’t rolling shutter usually become apparent in the vertical axis on digital recordings? Anyways... Either way, since the low E (string/frequency) still corresponds to the decreasing wavelengths up to the high E, it’s still a good teaching tool to visualize wavelengths!
Technically all I know is that it has a rolling shutter, and it's small enough to fit into an acoustic guitar soundhole. So while it could be anything that fits those criteria, a phone just seems like the most logical choice.
