The speaker is the normal PSP speaker. The triangle thingys are pointing to the negative side.

if your asking how to wire the speaker and leds to sound chip its simply wiring in parallel

(https://www.acidmods.com/forum/gallery/2191_18_07_07_7_48_52.jpg) Thats the 5v and GND. If you want to put a bigger speaker, i would just wire them parallel with the regular speaker.

wat if i want to put both the speaker and the leds with a lm386 chip how would this work

I never tried but I think you just wire the speaker if it was another LED. I tried to just wire a speaker with the LM386 and it didnt turn out well. It gave the speaker more bass but it sounded not very clear and a little fuzzy.

you would have to adjust the frequency going to the speaker so as to clear it up...

the THD for that amplified chip when using it for sound is quite high i would imagine


off to work i go, laters

If you wire in a capacitor it should keep distortion down.
