DIY Bluetooth Speakers

DIY Bluetooth Speaker

Bluetooth Speakers are becoming more popular these days being portable and handy. One can easily connect it via Bluetooth to his Smart Phone or Laptop anywhere once its charged. One can also easily charge it with normal phone chargers or even with USB port from Laptop.

In this Project, we’ll be making DIY Bluetooth Speakers to have cheaper solution to it. Parts which are required for this project are as follows:

  • Two Speakers 3W
  • High Efficiency SMD Amplifier for 2*3W
  • Stereo Bluetooth Module
  • 1000mAh Li-ion Battery
  • Li-ion charging module
  • 3.5mm Stereo Jack
  • Small Switch
  • A case (Eye wear case will be best)
  • Spray Paint of your Choice
Tools or Equipment
  • Soldering Iron
  • Glue Gun
  • Super Glue
  • Drill

Step-1: Marking and Drilling

In the beginning, get your case along with all the parts and plan for the placement of every part. Mark your speaker, audio jack, switch and charging port areas and drill them out. Recheck every part for its perfect placement as if they are easily ducking in or not. Then take a sand papers and smooth en every edge you just drilled for its neater look.

Step-2: Paint

After smoothing every edge of the case there’s a time to paint it. Select your favorite color in your spray can. I’d recommend to go with matte black as it gives neater and perfect look to your DIY Bluetooth Speakers. Apply at least two coats of the paint.

Step-3: Hot Gluing

After the paint dries completely, its time to attach every component in place perfectly. At first, place in the speakers in their holes and apply hot glue around them carefully along with switch, charging port and audio jack in their respective holes. Hot Glue amplifier, Bluetooth module and battery to the base of the case. Carefully seal every tiny hole to make Airtight otherwise it will sound like crap.

Step-4: Soldering

Following the above given circuit diagram, solder out every component to the right connection and secure it perfectly. It requires a little electronics experience, you can also take help from someone in soldering process. After everything is soldered, it will look something like this.
