Better sound, better speaker
Re: Better sound, better speaker
Thanks for the replies. I went for the Visaton speaker in the end.

When you modified the original ring in the GB case, was that cutting the lip of the speaker holder and moving it apart slightly? I'm using a Common ground 4 button PCB, so will check how much space it leaves.

Re: Better sound, better speaker
Are the two connectors for the speaker those little metal legs with the holes in?
Edit:- Managed to fit the speaker in, but i didnt realise that it prevented the common ground 4 button pcb from seating properly. I ended up just shaving a bit off the pcb, though did get.quite close to the tracks on the back!

Re: Better sound, better speaker
Hi. Sorry for the delay in replying. It's still a WIP, so the speaker is only connected to the PAM8403 atm. I'm still not 100% sure how I'll wire that, the USB DAC, headphone socket and eventually the Pi up. I'm having a bit of a break atm as I'm struggling soldering the close joints on the Common Ground PCB. The holes are too close lolMegavolt wrote:Yes those are the connectors ! Do you have some images to share ? =)

Re: Better sound, better speaker
Sweet. Super excited about getting started on my second build, and I just finished my first one last night. Not super excited to look at my credit card statement though.
With this second build, I figured I'd go all out and do it right. And with Helders AIO that will eliminate a lot of the mess of wires, I figured I'd go with the bigger speaker.
Anyone have any issues with putting a larger speaker in other than trimming it down to fit? I guess I'm hoping Helders AIO leaves enough room for it. Just curious if someone's seen any negative effects after using one for a while now.

Re: Better sound, better speaker
I use this Speaker
http://www.ebay.com/itm/321501717358?_t ... EBIDX%3AIT
The sound very high and pure
After i cut speaker edges , and a little of gameboy housing . it's fit perfect with AIO

Re: Better sound, better speaker
I don't know anything about speaker technology so maybe someone could enlighten me. I've seen that my amp board can handle 4-8ohm speakers and on the speakers I have ripped out of stuff over the years they are marked anywhere from 0.1w up to 1w and are 4 or 8ohm speakers. I have always assumed that using a lower wattage means it will use less power and that a lower ohm value means it's a higher quality speaker, but maybe I'm totally wrong?
Can anyone please tell me which would be best in this range I've stated above? Would a 4ohm 1w speaker use more power, but sound better? And to save power a 0.1w 4ohm speaker would be best?

Re: Better sound, better speaker
Ohms value is the amount of impedance (resistance) the speaker puts on the amp. If you don't use the correct impedance speaker for your amp design it can overheat or burn out.Zero wrote:I don't know anything about speaker technology so maybe someone could enlighten me.

The watts value is how much power the speaker can receive before distorting and possibly burning out. The higher the value, the louder the speaker can get (but you need a sufficiently powered amp to feed power to the speaker). I don't think the the watts value on speakers directly correlates to how much energy is drained from the battery since the amp is what supplies the energy. You need a more efficient amp if you want your battery to drain less.
The quality of sound a speaker can produce depends mostly on the materials that the speaker is built out of (and even the shape of the speaker can make a difference). Cheap thin plastic speakers can't produce sound in as wide a range as a larger speaker made of higher quality materials.
Re: Better sound, better speaker
I'm wonderig if it's possible to fit this speaker in alongside Helder's AIO board. I'm thinkong probably not since i already had to trim a (broken sadly) common ground pcb.Megavolt wrote:Cannikin did a very good describtion.
I cut the edges of my speaker off and modified the plastic ring in the original GB-case. I did fit in very thight, just added some extra hot glue around the speaker just to be sure. As cannikin already said, don't cut too much from the case. Do it step by step and try to fit your speaker into it time by time.
Re: Better sound, better speaker
Please could you do me a favour and measure the diameter of your speaker? Im trying to see if its the same size as the Visatonic one i used aboveABH wrote:I use this Speaker
