Now this thing has an internal speaker. I opened it up and pic related is what I found. Unfortunately, this device does not have an external audio jack.

Get an op-amp and maybe a larger speaker. done.

So should I solder a jack to the speaker's connection points and run that to an amp like this?

Or, if i solder in a jack, can i just run it to a more powerful speaker like this (from some else's build)?

Okay, but as I said, I am a moron. Could you please elaborate or point me in the direction of a tutorial?

Anyone?

Depends totally on your use case. perhaps u could elaborate on that in order to help you.

I peronally would go for a switched 3,5mm audio jack. to keep the integrity of your device as intact as possible and also to make it as versatile as possible say to use it with a guitar amp, intercom, hifi etc as said depending on your
>reasons.

Okay, I'm using this to add audio effects to Space Marine costume I would like to build. The unit currently runs of four AAA batteries and the speaker is a piddly 2 watts. While okay in my apartment this probably isn't going to be loud enough in public (read:conventions).

I have a small amp kit in >>1101293 which uses a 3.5mm jack, which will need it's own power supply (i think?) as it runs on 6 - 14 vdc. The whole set up will have to run on batteries - but I have lots of space in the costume itself to house that.

Pic isn't mine.

If that worked for them, give it a shot. If it doesn't work, that would make a great spot to connect the amp.

Well I'm worried about burning out the module. And that jack is after market. I think he connected it via the speaker contacts, but I'm not certain. Would that work? These are pretty rare these days.

Look at voltage you are you going to work with, it may have to have its own power source.
Look at mono or 1 channel amps.
Solder something up, datasheets should have an easy schematic for whatever you find. Wire this amp up per your schematic, but audio in will come from the red and white wires going to the speaker. Then wire up a new speaker to the audio out pins.
