In this project, we will have a look at a simple way to convert your cheap USB speakers to something that sounds better, looks unique and is Bluetooth.

Treasure chest Bluetooth Speaker

I made one of these a year ago. I was impressed with the sound, look and the Bluetooth function, so I decided to make another improved version.

What do you need?

  • Mini treasure chest
  • USB Speakers
  • Bluetooth 3.5mm Audio transmitter

    You can get them super cheap on eBay

  • Illuminated rocker switch
  • Cable with the plug
  • 2 x USB wall chargers
  • Female spade connectors
  • Heat-shrink tubing or electrical tape

    I drilled holes for the speakers, cable and the switch.

    I used some acrylic paint, so newly drilled holes don't stand out.

    At this point, I thought I'll go for the same look that my old speaker had. That's why, I painted more parts that it was necessary.

    Step 2:

    I took apart the cheap USB speaker.

    It sounded very bad.

    What can you expect from a thin plastic, that you can cut with the knife?

    To avoid unnecessary soldering, I cut out all the cables from the plastic case.

    I decided to use the front part from the speakers.

    Using nail polish remover, I got rid of the logo.

    Then, I glued speakers to the plastic.

    Step 3:

    I took off the plug from USB chargers and glued them together.

    Then, the wire was fed into the treasure chest and knot tied, so it can't be pulled out.

    I decided to use fake leather to decorate around the switch.

    I am not sure if it was a good idea. It might have looked better without it.

    Then, I attached the connectors to the cables and connected them to the switch.

    Connection will depend of the switch you are using.

    Not all illuminated switches are wired the same.

    I used the plastic fixing from the original speakers, to secure the board.

    Then, I plugged in speakers and Bluetooth dongle and the audio cable.

    There is not need to access the volume control as all Bluetooth devices can regulate the volume.

    I turned the volume to maximum and then turned it down just a little bit.

    After making sure that it works, I attached the speakers to the treasure chest using screws.

    The sound is very good. Much better and louder than original speakers.

    The reason I used 2 x USB chargers instead of a chargers with 2 USB ports is because of the noise.

    When I was making my first speaker, there was a noise introduced if Bluetooth dongle and the speaker were powered from the same charger.

    Using 2 chargers solved the problem.

    In the picture you can also see my first speaker.
