Introduction: Wooden Portable Speaker

About: I am 25 years old Polish "teen" (was... xD) :D I play electric guitar, like programming and arduino :)

Hello!
A few months ago I have created this beautiful portable speaker :)
It has only 3W (if you want more you can use other amp) but this is enough powerful to "lake play".
At the end you can see, improved version with high-freq speaker on the top and handle.
Let's see it :)

(Sorry for the poor photos, they come from messenger :/)

Step 1: Parts:

Case:

  • Large MDF (6mm)
  • 3x A4 felt peaces
  • Some screws & brackets & nuts
  • Thread (to sew felt)

Electronics:

  • Speaker (100mm, 3W, 8Ohm)
  • PAM8403 (3W stereo amp)
  • 18650 cell
  • Jack 3,5mm socket
  • Socket for charging cell (for example microphone socket or jack...)
  • Switch
  • Logarithmic(!) potentiometer
  • Wires

On photo you can see 2xswitches and more holes - no matter :P

Step 2: Cutting MDF

You need to cut from MDF:

  • 2x 125mm x 125mm (UP/DOWN)
  • 2x 125mm x 113mm (SIDES)
  • 2x 113mm x 113mm (FRONT/BACK)

In one 113 x 113 you need to drill a hole for a speaker and in one SIDE plate you need to cut smaller hole (about 25mm).

Using sandpaper you can smooth holes and edges.

Step 3: Connections an Felt

Before connecting wood parts ( screws , brackets , nuts) you need to fix felt to the walls . I sewed them , you can use glue or stapler.

For better sound you could put inside wadding :)

Step 4: Wires...

Wiring is very simple as you can see.
I connected left and right channels to one speaker through potentiometer.

Thats ALL! :D

Step 5: Improved Version

This version has a handle and high frequency speaker on the top (connected parallel to the main speaker).

Have a nice day :)
