So I've had my WonderSwan open for a while, doing stuff to it such as adding a front light from a GBA SP (works/looks good, but is a bit too reflective... oh well). The stock speaker is a piece of crap, though. I wired up a PSP speaker, and it works, but it's far too quiet, and a bit muffled. I understand that the PSP speakers are around 3v, whereas the WonderSwan's power source is only 1.5v. You can get 3v from the C51 capacitor (this is how you power the light), but I'm not sure how to draw the extra power to the speaker.
I assume the speaker must stay wired to the two speaker terminals, SP1 and SP2, on the PCB, else it won't work. I tried adding an extra wire from the negative battery terminal to SP 1 (AND SP2 - I tried both, but not at the same time), but it just stops the speaker from working. I doubt that's the correct way to increase the voltage, anyway. I'm not great at electronics, but I believe voltage is cumulative, so if it's already drawing 1.5v, I need to add another 1.5v, and not just tap into the 3v output from the C51 cap. I could be wrong, though, especially since what I was attempting with the wire was most likely making it run in parallel (but then again, like I said, I'm not great with electronics).
If anyone can point me in the right direction, I'd appreciate it. This is driving me insane. I just want to get this thing back together.
Oh, also, the light makes everything a tighter fit, so the only thing I can think of that I could remove is the padding on the PCB that the screen rests on (the same as the stuff on the back of a GBA SP screen). Is it detrimental to the screen if I remove this and just layer electrical tape underneath? I'd assume so. Is there perhaps a simple way to cut it in half? There doesn't seem to be, but if someone has any tips, it'd really help.
