    Hi, I have a pair of LogiTech speakers. It has only a USB to plug in my Macbook.

    No line in, no 3.5mm jack nor RCA jack. It is a decent pair of speakers and I would like to convert it to bluetooth capable.

    What I need is a Bluetooth receiver, I guess. A receiver that can output audio via USB to the speakers and gets power from the USB on the speakers, battery or external power supply.
    I don't seem to be able to find a device like that after googling. Does a device like this exist? If so, what is it called?

    It is called a computer. I doubt any other solution will work. If you REALLY like your Logitech USB speakers go buy something like the Raspberry Pi, a USB hub and a Bluetooth adapter and stream the audio over Bluetooth. That said though I highly doubt that it is cost effective given that Logitech USB speakers are typically quite cheap.

    How would a computer help? DA?
    I figured out how I can get this done.
    I don't know about the others, I did not grow up with the mentality of throwing things away, not to mention I spent a bit over $100.00 for this speakers few years ago and the speakers are in perfect condition. With a little thought and modification internally, I spent less then $10.00 converted it into a bluetooth speakers, which can be used on my Macbook Air, iPhone and iPad. :)

    I suggested a computer because you asked for a Bluetooth receiver that outputs via USB. I suspect you didn't solve that problem but instead just removed it all together. If you did find a way to convert the USB input to Bluetooth for cheap you should share what you did as its a fairly common question posted on various forums.

    There's going to be bandwidth and power issues.

    Most speaker system have either aux in or line in or both, but not the Logitech I have. I took the circutries out and traced down where the audio to the amp is, soldered a 3.5mm aux input, (something Logitech should have done in the first place) I bought a bluetooth audio receiver from Amazon, the receiver has a 3.5 mm and RCA aux output . It works perfectly! :)

    To accomplish it with a computer, I would have to do it on a software level, write a software converter which is over killed.
