I think this is highly possible, though i don't know how powerful of a speaker the DS could handle, anyone have any info/ideas?
#103455 - Lynx - Fri Sep 22, 2006 3:26 am
I don't think it is really possible at all if you plan to retain the original case and look of the case. First, you have to take into account the space. Any "decent" speaker will most likely have a heavier (bigger) magnet. Basically, the speakers are a little bigger than headphones.
Then, you have to match the impedence (ohms) to the current speakers or get higher impedence ones.. which will reduce the volume. If you get lower impedence ones, it will increase the volume but add stress to the internal amp, and if you go to low you will most likely blow the amp or the speakers, as most speakers are blown due to distortion, not over power, and running lower impendance speakers will cause the amp to distort at a lower volume setting.
Idealy, you would get better quality speakers and also add another amp to power them.. but, good luck getting them to fit into what is already a pretty small space as well as power the extra amp if you add one.
You'd be better of trying to make a "speaker docking station" that the DS would plug into that used 'C' or 'D' size batteries to power the speakers with an internal amp and just plug it into the headphone jack on the DS. The quality of the output of the DS is quite good. Plug it into your home stereo system (if you haven't already) and see how nice it actually is. Even with a nice set of headphones the quality is pretty darn good.

Yeah, I often plug it into my home stereo, not a great system but it does sport a very very nice pair of speakers and the DS's audio is great :-)

OMG! I never thought of plugging my DS into my Stereo System...GLORIOUS :D
#103536 - Jabba - Fri Sep 22, 2006 6:38 pm
LoL, Yeah, i have plugged them into my stereo speakers before and the sound is just, wow, you can hear things so much better, one reason i want to improve the ones in my ds, im thinking of other portable devices that might have better speakers or... crap. i forgot what i was gonna say, well i know theres that speaker dock you can buy, but im trying to avaoid making the phat fatter, lol. Why cant i remember what i was gonna say >_<

#103598 - zzo38computer - Fri Sep 22, 2006 11:07 pm
Also, if you put the speakers in the same NDS case then you will need to match the magnet strength and position of the speaker as well (at least on the right speaker). If the magnet isn't strong enough it might not work

I think it'd be much easier to make an add-on that plugs into the headphone jack than to try to fit better speakers into such a small case. Or you could just get some nice headphones.

I remember what i was gonna say now, i was thinking of taking them from other portable devices with high qualiter speakers... that idea sucked, but after hours of searching i came across these
http://cgi.ebay.co.uk/PORTABLE-CLIP-ON-SPEAKERS-FOR-IPOD-MINI-NANO-VIDEO-MP3_W0QQitemZ250032384616QQihZ015QQcategoryZ111694QQrdZ1QQcmdZViewItem
small, no external power reguired, only thing is, will the quality and volume be good? Their cheap so i dont really mind buying them to see, but chances are they cant be that bad if they were made mp3 players in mind.
The specs for this are in the auction, but ill post them anyway
Specifications:
No extra batteries or AC connection required
Maximal power: 400mW + 400mW
Impedance: 8 Ohms
Driver unit: 28mm diameter gamut x 2
3.5 mm diameter stereo plug
Compatible with iPods, MP3, CD, MD, walkman, PC, laptop
Cord length: 1.2 metres
Size: 65 x 34 x 24 mm
Now i need to find the ones for the DS speakers. *goes looking*
#103729 - Lynx - Sun Sep 24, 2006 6:36 am
Go for it, but I think you will find that they are worse. They are designed to be driven from the headphone jack.
But, does anyone know the impedance of the internal speakers of the DS?

Hmmmm, not sure...
I'm using a pair of Koss KSC-75 headphones are they're a definite improvement over the DS's speakers. Very definite :-)

If you don't know..there is a DS speaker that uses AAA batteries like the ipod speaker you have found.It is exactly like the ipod speaker but bigger and you cannot use big flashcarts cause it is somewhat big,atleast in the picture.
#103782 - Jabba - Sun Sep 24, 2006 4:04 pm
Well, if i wanted external speakers, id get these
Please use the [url=] syntax for long URLs. -- MOD
I might get them anyway
But i want do a mod, that will improve the speakers, like experimenting, ive got a spare DS, if this one dies, i still got another one to play on. The point really is to improve the DS rather than just a newbie question asking for louder sound, if you catch my drift? :D
#103783 - OOPMan - Sun Sep 24, 2006 4:28 pm
Well, like Lynx said in the 2nd post on this thread, modding the actual speakers could be a problem, if you're aiming to improve them anyway...

Yes, like I said, it depends on what you are really looking for. If you don't mind cutting a hole in the lid of the DS to make room for bigger magnets, then it might be possible..
Jabba, have you even opened the DS up to see what the current speaker imedence is? And what impedence the speakers you linked to are?
The feeling I get:
Speakers fit, and sound better: .01%
Speakers fit, and sound worse: 40%
Speakers don't fit and sound worse: 45%
Speakers fit, and blow the internal amp: 9.09%
Internal shorts from mod blowing something: 5%
Chance of a broken DS: 98%
Chance of a DS in parts, but still working: 2%
Project success (that being, replacing the speakers, them sounding better, and the DS going back together and no shorts): 0%

Yeah i have opened it, (but that doesnt help any does it), but me has no multimeter to measure it. The ones i linked to is 8 Ohms
i agree with your "feeling" I pretty much feel the same way.
One other thing i was thinking, was building the speakers in where the current ones are and maybe wiring them from the headphone jack, sound better?
Is there anyone out there with a multimeter to measure the impendence of the DS speakers?
#103846 - HyperHacker - Sun Sep 24, 2006 11:21 pm
Couldn't you put in a bigger amp, if you could fit it in?

Where is the amp located?
Wouldn't that increase battery drain?

Yeah, i reckon ill get a battery upgrade, i saw one for the phat that was 1200mah but i cant find the site, only the ds ones coming up >_<
#104099 - Lynx - Tue Sep 26, 2006 4:23 pm
I don't believe just putting in a better amp will help anything either. I think you will find that you get the best sound + safety with an externally powered speaker that plugs into the headphone jack. Headphone jacks aren't designed to power external speakers, except for the ones sitting on you ears, which don't need near as much power to sound good.. because they are sitting on your ears.
So, even if you upgrade the amp, the speakers are matched to the internal amp and would probably either sound bad, or just blow. The main issue is space and nothing else. Speakers and amps are pretty easy, you just need room to fit them.
So, unless you are willing to mod the case, I don't see it possible to actually get any benefit out of it, as "sound quality and volume" is hard to measure by ear. If you don't have a multimeter, I doubt you have a decimeter either.

Im listening, hes my guide :D a case mod wouldnt be a bad idea, the speakers i linked to dont need a power source so theyre like headphones, thats why i thought to connect via the headphone jack, though i guess the issue is the sound quality, i guess ill have to buy them to find out.

The idea is to replace both the amp and speakers. Also, many multimeters (at least, a cheap one I bought at a local hardware store) also function as decimeters.
(Is decimeter even the right word? I always thought a decimeter was 10 centimeters.)

Thats what i thought, lol, weird thing, i swear when im running homebrew my DS speakers arent as loud 0_o even in moonshell hen i put the volume up. Maybe im just going deaf.

Huh? Where do you live? There is NO Multimeter that I have ever purchased that have measured sound level. I have like 4 or 5 of them, all in the cheap range, I know FLUKE makes meters that can measure just about anything, but then again, they aren't cheap!
I just checked and I was spelling it wrong.. It's dosimeter.
Anyway, it's used to measure noice/sound and uses a very sensative microphone to measure decibels (db).
You still have the problem of space.

Out in the middle of nowhere, but I imagine they can be purchased at any Home Hardware. That's what brand it is if I'm not mistaken. You have to actually connect the leads to the sound output somehow, but it works.

Then it's just another voltmeter.. You have to have a microphone to measure sound pressure level, as you are actually measuring the amount of air that is being moved. You can't measure that any other way.
Docimeters are commenly used to configure a home theater system so that you can tune each speakers output level to the proper amount to create a "sweet spot" at the center of your couch or chair. Newer system have one built in, where you just place the included mic in the "sweet spot" and it will auto adjust all the speakers outputs to the proper level.. it's actually pretty awesome, as it does sonar type ticks to measure distances and stuff..
And of course, they are the device used for automotive Sound Off competitions (reason I purchased mine). Mine only goes up to 120db which isn't enough to run a system wide open, but is very helpful in figuring out what frequency to play to get the best cabin gain out of a vehicle.
