Is what doable?
Powering your existing speakers from USB? Maybe, maybe not, there's not enough info. Do any of them run on 5V (look at the soap-on-a-rope power adapter. If any are 5 VDC and <500 mA, probably (may depend on laptop). If any are 12 VDC, you should be able to cable them into a standard 12 VDC cigar lighter outlet ("DC Outlet" in modern, politically correct, terms).
If any speaker, a lot of the rechargeable Bluetooth speakers available recharge via USB, will run while USB powered, and also have 3.5 mm jacks. If the laptop has Bluetooth, you could even avoid the cable - those small speakers don't have enough fidelity for it to make a difference in sound.
Or, as the title implies, do you want to power all ("multiple") speakers from USB? A single USB port, nope.
Be clear in what you're asking.
