i want to put a speaker on the umd door of my psp the speaker is the size of the inside circle of the silver thingy i want to put a lm386 amplifier chip in ther also and some LED's but don't know how to wire anything

is the speaker in that diagram the internal psp speaker or the new one
also what are the triangle thingys
-
The speaker is the normal PSP speaker. The triangle thingys are pointing to the negative side.
-
dude your awesome almost every question i ask you answer thaanx and if you could tell me were my new speaker and leds would go in this circuit could you show in a pic or something that i easily can understand
-
if your asking how to wire the speaker and leds to sound chip its simply wiring in parallel

-
so the triangle thingys are leds and could you explain why i need the resistors in on the psp stock speakers
were in the psp is the 5v negative and positive points and also wat is the ground were is it in the psp and wat is its need

(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.

@psp339
so what exactly did you use........ (capacitors, lm386,etc :beg: include pics plz)
-
psp339 would you think this is right

This is how i wired it but the sound came out blurry but more bass.

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

-
ya how would you adjust the frequency going to the speaker
also are the mmaybe its because you didn't put resistors psp339(https://www.acidmods.com/JR/WiKi/PSPSoundMod/MonoSoundMod.jpg)

-
i used the resistors...
-
well then i don't have a clue
(https://www.acidmods.com/JR/WiKi/PSPSoundMod/LM386Pins.jpg)
also does anyone know wat pins 1,8,and 7 are for
-
If you wire in a capacitor it should keep distortion down.
-
wat type cap. would i need to use i have many different types
-
looooooooook at this it makes sense in some ways
