Introduction: Portable Wireless Bluetooth Speaker

By

We made a blue tooth speaker that has a rechargeable battery so we could listen to music on the go.

Step 1: Circuitry

First, we put together our circuit.

  • We tried to use minimal soldering until we got the wiring right.


Step 2: 3d Printing and Laser Cutting

We 3d printed the casing for the 3d speaker using the Taz Lulzbot Mini 2.

Afterwards, we laser cut circular shapes that connect to the speakers and circular shapes with a waffle pattern to protect the speakers. We also laser cut the pieces for the wood stand.

  • Files are included below.
  • 1x speaker box
  • 2x wood circle pieces
  • 2x speaker+legs
  • 1x speaker+legs+connector
  • 2x cover

Step 3: Wood Stain

At this point before anything is glued and assembled, we wood stained all of our laser cut pieces.

We used black wood stain to do so.

We stained the wood with one coat and let the pieces dry over night.

Step 4: Hot Glue Speakers to Wood Pieces

The wood circular pieces go on the outside of the speaker and should fit snugly. Apply hot glue to the corners of the wood pieces and the speakers to keep them in place.

Step 5: Soldering + Assembly

We made sure our circuit worked then finalized it by sawdering.

  • Make sure while soldering you leave one speaker un-soldered and both the switch and charging port un-soldered until they are in the correct spots.
  • Insert components into the speaker casing. Pull the wires that go to the switch and charging port through the corresponding holes. Solder the wires to the switch and the correct wires to the charging port. Then insert the switch and charging port into the case. This might require sanding.
  • After you insert the charging port use the included nut to keep the charging port snug.
  • Proceed to pull the wiring through the casing that connects to the un-soldered speaker. Solder the speaker to the correct wires.
  • Put a small amount of hot glue (super glue will work also) and press both speakers into the casing.
  • Finally, put a small amount of wood glue around the wood pieces and press in the waffle shape on top.
  • We used clamps and let the glue dry over night. If you do not have clamps you can turn the speaker on its side and put a heavy object on top.

Step 6: Finished Product
