The transducer is pretty small but there is typically a cavity around it
in the phone, with a tuned port (= judiciously placed and sized hole in
the phone).  90db at 250hz is asking a lot from a phone though.  You
might be "hearing" undertones of the frequencies that they do reproduce.
If you have a serious requirement then better use an audio spectrum
analyzer and calibrated mic.

Th style of dinky little external, enclosed speaker generally sounds
better than phone or laptop speakers:

There's lots of sub-2" speakers on adafruit and sparkfun.  You could
also try something like this, depending on the surrounding device:
