Step 3: Connect Circuts

Use the picture, included above, to wire your speaker.

Step 4: Attach the Wiring to the Case

Glue the components to the inside wall of the speaker, as shown below.

Hot Glue should be used to secure the components to the wall.

Make sure that the glue gun is not kept close to the component for too long, to avoid heating the circuit.

Step 5: Attach the Backing

In these pictures, you can see how the backing is oriented.

The side with the female end of the plug is on the bottom along with the switch.

The green circles show where the plug and switch are in relation to each other. The mentions of top and bottom, are simply relational, to show how the backing should be inserted.

Step 6: PLAY YOUR SPEAKER

Plug the male end into the female end, and turn it off. This will allow your battery to charge. The light on the charging board should be red when you start charging and will turn blue when the battery is fully charged.

When you connect to the speaker via Bluetooth, it will show up as DW-CT14+. In settings, you can then customize the Bluetooth name of your speaker.


Congratulations! You have finished your Bluetooth speaker.
