I've discovered that the speakers I want to use on my computer wont put out enough sound without an amp so I'm gonna build a small amp inside each speaker that run off the 5v from a mirco usb. For the amp I've been looking at the LM386 family of op amps but am confused what Vs is, not really a big problem (I hope) just can't figure out what its for.

BTW the "Vs" in some of the other drawings is the Audio Signal in. + and -. If you look at them the "Vs" had the same symbol as the main postive power in.
