Introduction: Portable Wireless Bluetooth Speaker

By

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

Switch

Machines Used

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 to fit to the sides of the casing.

Step 3: 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 inplace.

Step 4: 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.
  • Press both speakers into the casing.

Step 5: Wood Stand

Finally, it is time to create the wood stand pieces that the speaker lies on. To do this, we laser cut pieces for the speaker to lay on. Putting the pieces together might require sanding. Those files are included below.
