It's a Small Box with Big Bass
(at least that's what i want it to be...)
https://youtu.be/05p6EjRsf4E
Note : the microphone of the camera really doesn't do justice to the sound :-/
Features :
- True extra bass sound system with Xtra Long Pass (© XLP) passive radiator, doesn't sound as cool as it's name but not bad either
- class D amp between 10-15w rms
- 2x 18650 battery (should get 10 hours at reasonable level)
What you have to put inside :
The one in picture is pretty decent
- some capacitor to smooth current spike (I put 2200 + 3300 /25V at the amplifier voltage input and 2200 10V at the step-up input)
- one power button, one Led with it's resistor and 3 push button
- a USB plug, I put one diode (1n4004) on it to charge the li-ion
- 2x 18650 lion in parallel (you could go with only one if you want)
- some screws
- soldier skill and a creative mind, this is not a ready to assemble kit, for example you have to figure out where to drill
Some hints :
- print with at least 50 % infill or more to make the box sturdy
- Glue everything inside before the last closing to avoid any rattle
- add some light foam or glass wool
- Make the box as watertight as possible to improve bass (I put some tyre tube on the back but you should better glue it all or "PLA solder" it)
- glue the border of the passive radiator
- do the wiring in order to be able to charge it even when it's off. The power button should be on the li-ion to be sure that when it's off nothing discharge the li-ion
Listening test :
- It's definitively louder than my JBL go2 which was the goal !
- I find it pretty descent with correct bass response.
Note that the one in picture is a prototype with different speaker
The original solidworks files are here, feels free to mods as you want !
I only demand some pictures of your creations ^^
