I have found layout like this. Which spots should I connect 'left', 'right' and 'ground' from my computer audio?

Your speaker thing is using a usb connector out of spec.

A fairly safe assumption is that it still uses the +5v and ground pins as normal so you could charge your box thing with any standard usb outlet.

The line in presumably runs on the data pins then. Ground is ground. Left/Right goes to data- and data+ respectively. Or reversely. There's no real way to tell without experimentation, and most sound cards will just let you flop the channels if you get it backwards on your connector.

Easy as pie. Just take the audio cable for your pc, cut one end off of it, strip the ends of the wires so the copper is showing, solder them on to an analog to digital converter, then solder the ADC to an audio over USB digital module. Finally, connect the audio over USB module to a mini USB cable and you're done.

You'll probably need a 5v supply, some breadboard, the ADC chip, the audio over USB chip, some assorted caps and resistors, and possibly some jumper wire too.

>Ops shitbox speaker has a usb host controller in it.
>'LINE IN' means it has a driver for a usb audio device.

Thank you, my good sir :)
Yes, it's charging allright and my only concern is the audio connection. I will figure out right/left somehow, anyways I need it only for some stupid lectures so I don't care about quality.

>audio connection concern
You sure that thing aint Bluetooth?

Find model no on box if poss:

(see nothing, click on 'speaker' again top menu)

6 models, 3 BT, 3 nopeBT.

Manual link(s) do nothing, but, nonBT models appear to have additional (standard) 3.5 line in - and retard level of the rest of the setup suggests, anything (standard USB, abused USB line-in/5v power combo, whofuckingknows) be possible. Dont seem to sell these in English-speaking countries, maybe marking USB power sockets on audio devices as 'Line-IN' is a thing elsewhere, I dunno. I'd doubt it actually functions as USB tho.

The thing was bought in Russia, pretty common piece of Chinese technology though.
I tried 3,5 outlet as audio in, but for no luck. Everything went pretty much as that guy said. I connected green wire to green on headphone jack, white from USB to red on jack and ground to black. Didn't work before I plugged power to USB.
