LM386 is a very weak amp, specially if powered fromth +5V rail an USB connector provides (some 300mW, what a pocket radio provides) .
You CAN of course but they will be as bad as any $5 cheap PC speaker you can find anywhere.
Not worth cloning *those*  ;)
To make a KILLER PC speaker, make at least a TDA2003 based amp (some 5/6 W RMS per side ) driving a couple 6" full range speaker (the ones usually mounted in car doors) or better.
Light years ahead of any regular PC speaker.
It will need its own PSU, a 12V transformer, a 3A bridge and a 4700uF x 16V capacitor.

Or go the next step, 2 x TDA2030, powered from a 12+12V transformer and 2  4700uF caps , you will have 15 + 15W RMS for a room blasting system.
Also driving full range car type speakers. in this case a couple 6"x9" ones.
