Hey! everyone My name is Steve .

Today i'm going to show you How to make a Carbon Bluetooth Speaker Build as written on the tittle .

Since , Bluetooth Speaker are very Popular Today

I've been searching a Best Bluetooth Speaker for long year and years .

Finally i made it

Let's Get Started

Step 1: Features

Output

  • 2 * 15 watt = Total 30 watt of power

Battery Backup

  • 5-6 hours at full volume
  • 10-12 hours at medium volume

Step 2: Stuff I Used

List with Buying Links

  • Passive Radiator click
  • 2.5" Full Range Speaker click
  • Bluetooth Module click
  • PAM8610 Amplifier click
  • Dc Jack click
  • On/Off Switch click
  • 3.5 mm Female Jack click
  • Dc to Dc step up converter click
  • 25v 1000uf Capacitor click
  • Carbon Fiber Vinyl click
  • 10A BMS Charger Protection Board click
  • 18650 Battery Holder click

  • Panasonic 18650 3400mAh 100% Original click

Step 3: Starting With Amplifier

There is a Reason i use this Amplifier Bluetooth module is not build in but no worry i can use a external module in other hand you got very powerful amplifier .

it need 12v to run at max power .

it can deliver 15 watt each at 4 ohms

You can use built in Bluetooth in a amplifier board " Click here to see the amplifier "

Step 4: Power Source " Battery "

In this Project i'm going to use a 18650 3S Battery Pack If You want to know how to make a 3S 18650 Battery Pack Click Here to See The Video

It can Deliver

  • Maximum voltage - 12.6 v
  • nominal voltage - 11.1 v
  • Low voltage - 9 v

How to charge this Battery

  • You can just use a 12.6 v Lithium Battery Charger to charge this battery

Pack Safety Features

  • Over Discharge Protection
  • Over Charge Protection
  • Short Circuit Protection

"This BMS does not do balance charging "

I've shown how to manage the battery to does not get out of balance in the Video So please Check the Above Video Link

Step 5: Cutting Wood

I used 12mm MDF to make this

Dimension

  • Length - 25.5 cm
  • Height - 8.7 cm
  • Width - 9.5 cm

And then i used a router to make a dado cut " See the image "

Step 6: Drilling Speaker Hole

I used a hole Saw to Drill the Speaker Hole " See the Image "

And then i Used my router to make a 45 degree Angle cut in the hole

Step 7: Cutting for Passive Radiator

i used my jig saw to cut a square cut

and then i used some sandpaper to smooth the surface

and then i used my router to cut 45 Degree angle cut in the square " see the image "

And then Some more Sanding

Step 8: Gluing

i used some wood glue to glue all the parts

and then i used my router to cut Round Over cut over the edge "See the image "


Step 9: Giving It's Look & Installing Passive Radiator

I used Carbon Fiber Vinyl to wrap it over " i used heat gun to do it smoothly "

"See the image "

And then i used some Glue to stick passive radiator from inside

Step 10: Connection & Installation

Fit all the parts as shown in the image

Use some dual sided tape and hot glue to stick the battery

Connect all the connection as shown in the Schematics " See the image "

And then Install the Speaker

Secure all the electronics with hot glue

Step 11: Calibration

Now set the step up module to exact 12.5v with a potentiometer

Step 12: Closing

Now put some silicone adhesive to the back panel and close it

and then drill 4 holes and screw it

Step 13: It's Done Now

Now plug your Bluetooth module to 3.5mm jack and play it
