ELI5: Phone speakers are so incredibly tiny, but have an incredibly loud sound, and is usually pretty clear too. How?

One reason is that the phone cuts off most of the low frequencies, below a certain limit. With every lowering of an octave (1/2 the Hz), a speaker diaphragm has to move 4x the distance for equal volume. So by cutting off the bass they can get more perceived volume out of a smaller unit.
