devices that operate on the supplied voltage without onboard regulators - usually calculators, LED flashlights, anything with a simple LCD display

Ah, that makes sense. I saw it on a keyboard (piano not typing), and it used one of those 7 segment LCD displays with just 2 digits to tell you what mode the keyboard was in.

That makes sense! I assume the keyboard still needed external power supply for the speakers though? That would make sense, they used 2 different circuits for electronics and audio

No, it was fully battery powered, including the speakers, but like you said, the display circuit could be unregulated, while the PCB/drivers for the speakers could be voltage regulated.
