We need a simple (existing) solution to take the USB audio out from smartphones' USB port, and then DAC, amplify, and drive an external speaker.

We only need to work with the standard USB audio out. See image below.

In summary, we want the circuit from the USB audio output port of the phone all the way to the external speaker.

We only look for people who have the existing solution already.

Thanks for your interest.
