The 10k potentiometer will give the amplifier a variable gain from zero up to the maximum.
This circuit can be used to strengthen signals from the mini radio, music bell, and other children toys.

Simple LM386 Audio Amplifier
This simple amplifier shows the LM386 in a high-gain configuration (A = 200). For a maximum gain of only 20, leave out the 10 uF connected from pin 1 to pin 8. Maximum gains between 20 and 200 may be realized by adding a selected resistor in series with the same 10 uF capacitor.
The 10k potentiometer will give the amplifier a variable gain from zero up to the maximum.
