I got some helmet speakers for free from my work. I was hoping to just install them and them plug in a 3.5mm connection to my phone and play away. But the speakers have a mini usb since you "need" some kind of main hub to connect it to. So i was wondering if there is a way to convert it?

My soldering skills are pretty good but I'm not an expert. Maybe cut the wire and solder a 3.5mm wire would that work?

Or if anyone know of any adapter that will work? Best Regards!

  • \$\begingroup\$ Chances are it is digital if on USB and not analog for 3.5mm. So there may be a DSP chip inside you’d have to bypass. Try to Ohm it out \$\endgroup\$ – Tony Stewart EE75 Mar 21 at 15:20
  • \$\begingroup\$ Ohm it out, What do i look for and between which wires? I doubt that there is a chip inside these small speakers. + It's not the end of the world if i break it haha. \$\endgroup\$ – yep Mar 21 at 15:23
  • \$\begingroup\$ If they have a USB connector, there must be some electronics in them - perhaps in the USB connector. To use a 3.5 mm headphone jack, you will have to bypass any electronics and connect directly to the speakers. \$\endgroup\$ – Peter Bennett Mar 21 at 15:35

Solved it. I just cut the wire, soldered a 3.5mm jack, plugged into my phone and it did work. Very low volume tho. But that's another issue. cheers!
