- 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.
