Simply connect the speaker in series with a variable resistor of
maybe 10 or 20 ohms.  Speaker volume is a function of current, and
the speaker output is constant voltage.  At you increase the
resistance of the added potentiometer, the current flowing through
the speaker will decrease, leading to lower volume.  At minimum
setting (0 ohms), the speaker will be loudest.
