Homemade Wooden Bluetooth Speaker

Introduction: Homemade Wooden Bluetooth Speaker

About: I'm only a guy who likes to make things.

This is another amplified Bluetooth speaker made by me. This time the idea is to laser-cut the MDF previously covered by a sheet of wood to show the beautiful lattice pattern for curved edges of the sound box. I’ve used a light imbuia sheet to cover the entire equipment (only the back cover isn’t covered). The amplifier circuit board has the output power of 25x25 Watts and one can control it via Bluetooth. Following I show how the device was done. I hope you enjoy!


* Laser-cut MDF parts (see plans beneath);

* light imbuia sheet;

* 50x50 Watts Bluetooth amplifier board;

* a pair of 4” JBL speakers;

* 4” passive bass;

* tactil buttons board, to control the volume and the sound playing, made by me;

* glue;

* bolts and nuts;

Step 1: The Project

I sketched the design and developed it in the CAD program, defining the dimensions and final appearance of the speaker box.
The Idea was to do the assembly using 3mm MDF ribs, to ensure the lightness of the equipment and to improve its sound quality. One can check the project in the file I attached in this step.

Step 2: The Electronics

I have used a 4” JBL automotive speakers that came with a built-in woofer and tweeter, which facilitates the overall mounting.
To improve the bass frequencies, one passive bass was installed between the speakers. The 25x25W Bluetooth amplifier could be controlled remotely and also by the wooden buttons installed on the top of the equipment. The amplifier is powered by a 12V x 5A switched Power supply, mounted on the back cover. The pictures illustrate the electronics assembly.

Step 3: The Control Buttons Board

It’s worth to say that the equipment can be controlled by the buttons
installed on its top. By the way, the button caps are made of wood, glued with hot glue on the 12mmx12mm tactil buttons, whose PCB can be easily made by everyone, through the attached file.

Step 4: The Box Assembly

As I said, the box is mounted using
3mm MDF ribs, enclosured by 3mm thick MDF piece covered by a wooden sheet, to ensure the lightness and to improve the sound quality. The front cover is also covered by wooden sheet while the back cover isn’t. It’s worth to say that this type of mounting (using ribbing instead of hard wood) makes the sound better and can provide interesting shapes for the box. But showing pictures tells the assembly story rather than talking, doesn't it?

Step 5: The Final Assembly

After enclosing the equipment box, I proceeded to the final assembly.
Sanded and varnished, it’s time to get together all the parts.

Step 6: The Result

As seen in the pictures, this is the final appearance of my Bluetooth
speaker project. I hope you enjoyed the construction process as I did. Thanks for your interest!
