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:
- Large MDF (6mm)
- 3x A4 felt peaces
- Some screws & brackets & nuts
- Thread (to sew felt)
- Speaker (100mm, 3W, 8Ohm)
- PAM8403 (3W stereo amp)
- 18650 cell
- Jack 3,5mm socket
- Socket for charging cell (for example microphone socket or jack...)
- Logarithmic(!) potentiometer
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 :)
