You're saying that the DSP doesn't modify the wired input?

No. And I am not saying it does either. But good luck trying to program the needed filter and harmonics generation for psychoacoustic bass enhancement into the Kalimba DSP getting even remotely acceptable audio quality.

Basically I'm saying you can forget that idea. The Kalimba DSP is simply not powerful enough.

Small update just to say progress is continuing on this, but mostly on the design rather than the technical side at this stage. Neatened it all up and generally improved the aesthetic. The material processes/tolerances/limitations all seem to make sense to me and it all seems to be possible, still need to get a professional opinion on this but as I've revised and remade this design more or less from scratch dozens of times in the past few months I'm well enough positioned to revise it in any way that's necessary!

I'm looking to outsource the final rendering job for prototyping (3D printers) - there are a few designers for hire out there that work by the hour but ideally I'd like to find someone who believed in the project enough to work in advance as I'm working in a zero budget situation at this stage!

To give the design a balanced feel I've kind of obsessively gone through each measurement with the Phi (golden) Ratio 1:1.618, and almost all dimensions relate to one another in this way (this is roughly illustrated by the squares in the following images)

An externally hosted image should be here but it was not working when we last tested it.


Potential for custom grilles illustrated here + size reference to a 12cm diameter CD

Showing how the aesthetic has changed (improved?) from earlier renderings - a lot of which was necessary to be more achievable for parts manufacturing, but also from drawing the design in line with the Phi ratio as mentioned.

This one is slightly out of date but it gives a flavour of what's going on 'under the hood' - that's not a second driver or passive radiator (though it theoretically could be) - under the grille would be where any necessary labelling would be located (presumably this is legal as my Samsung phone has all that stuff under the battery cover), but the mould would be stylised in that place for visual balance.

More Phi ratio on the button/input strips. One of the smallest dimensions used (on grille bevels etc) is 0.314159mm and as all other dimensions relate to that through Phi the whole thing is also linked to Pi - I like to think that helps but whether it actually does I don't know.
