Need a small PI speaker powered through 3.5mm or usb

Zigurana

I power everything via the Pi itself, but then again, I use a 5A power supply.

@zigurana also, these measure very big :) I need something in the 2 " cube max size... Yeah i will be using a 5amp power supply as well. thank you zig

Zigurana

Well, I don't know your situation, but I dismantled them, using only the usb-panel and the drivers themselves. Those are maybe 7 cm in diameter, and 5 cm deep, so I was able to just squeeze them in my bartop.

dunginhawk

ok.. thank you sir... ill hold it as an option..

dunginhawk

zig. would you happen to have a link to a 5A PS for the pi? most i can find are 5v 2-3a
thanks

dunginhawk

@dunginhawk or perhaps you meant 5v smaller amp? 5 and 5 seems off.. but id love it if it exists.

I have something very close to this:
Single Output Switching power supply 5V 5A 25W Transformer 110V 220V AC To DC 5 V SMPS For Electronics Led Strip Display

@dunginhawk I used these speakers in my cabinet. They are connected to the 3.5mm and powered via USB. I un-shelled them and put the drivers into PVC tubes. Not sure if they would fit in your projects, but the amp kicks out adequate sound and has a tiny potentiometer to adjust volume (although I have it cranked to max and adjust digitally).

Caver01.. thanks.. ive seen those around... it may be worth picking up a pair to test.
Right now I just bought a 9.99 bluetooth speaker that I can connect via 3.5mm and it will charge through the USB on the pi.
I think that should work. Sound is much less important to me (dual channel etc).
thanks

Son of a ???? so this little speaker, while it will charge through the USB on the pi, the feedback at rest is loud.

once in a game its perfect, but there are no volume controls on the speaker itself to turn it down.
man this is a chore.

dunginhawk

this shouldnt be that hard.

Requirements.

USB for power (500Mamp or less draw preferably)
Volume control on the Speaker (the pi is just too loud until its in game).
2" cube or smaller
3.5mm for audio

anyone? :)

Is this the old audio hiss problem that is present on the 3.5mm jack? You can fix that with this command in config.txt:

disable_audio_dither=1

I am also following this thread regarding the use of a newer audio driver that is supposed to fix both the his and dramatically improve the quality of the 3.5mm.

I currently use the command above and have not tried the new driver yet as I am away from my Pi for a few days. Have you tried either of these?

dunginhawk

reading through that thread now.. the first suggestion didnt do anything to address the hissing :)
thanks...

dunginhawk

wait just one minute :) i misread your statement... I ran it from the command line instead of adding to the config.txt and it appears to be working...
Sweet jesus. thank you SOOOO much.

I do notice the sound is a bit crunchy in NES games, but the mame ones sound great.

dunginhawk

So I am looking at how to edit this

Update the retroarch.cfg file with audio_out_rate = 44100 Using that config the ALSA sound coming from the headphone jack is a lot clearer and has a lot less static.

I have searched winscp, and all over trying to locate this file to edit it. but cant seem to find that.
the sound is great in mame, but is really fuzzy in NES, hoping this helps.

EDIT - screw it... im giving these away, they can deal without NES games :) stick with mame, sound is good.

@dunginhawk the retroarch configs are described here. This page is about controller configuration, but the paths are there. You probably want to edit the global config. Just remember, these settings only affect libretro core emulators, not stand-alone.
