So as some of you may know, I got a new iPhone under warranty yesterday (due to a bad camera sensor... perhaps you saw my funky pics). So I decided to lay to rest any questions whether or not poking holes in the speaker actually does anything to affect the volume.

So here's what I did: I set up a microphone right against the iPhone speaker (actually touching it to eliminate any setup inconsistencies) and recorded the first few bars of one of my favorite tunes. Then I did the hole-pokey thing and did it again, exact same setup, same gain on the mic pre, still touching the speaker, and recorded the difference.


You can see from the pic that the difference is obvious. And the actual numbers prove it. With the setup I used, the unmodded iPhone speaker peaked at -8 dBfs while the modded one peaked at -3.4 dBfs. That's a 4.6 dB increase. Now for those who don't understand decibel measurement, it's exponential so that 1 dB difference you would barely notice. But 3 dB is quite a noticeable bump and 6dB is, technically, twice as loud!

So yes, this mod is worth doing. No one's punctured their speakers yet to my knowledge, and no one has been denied service by Apple because of it (hey, at least I wasn't!)

If you need more proof, check out the MP3.

Do it!

nice! I'm still not poking holes in my speakers. I have mine on vibrate most of the time anyways!

Thank you for showing this. I have noticed a great increase in the volume on my phone after doing this.

Come on boys, I'm the coward of the forum too afraid to JB, even I did this. Try it, it really works well!

Buffy, you really need to jailbreak your iPhone. The new ways to jailbreak are very painless and quick (like a good death) and there's a wealth of good third party software out there.

hehe, thanks. No video (though I thought about it).

Someone posted a picture of the inside of the iPhone that showed how much room you have before you hit the speaker, but I can't locate it now.

I'm a little torn on the speaker poking. On my old 8 gig, I did it and was pretty pleased with the speakerphone part, but the iPod sounded distorted. Now when I hang out with my friend who has my old iPhone and he plays his iPod, it makes me feel better that I never did it on my new one.

Well, the mere physics of the thing conclude that if you crank the volume all the way on a loud track.... it's gonna distort! Personally, I feel the phone distorted much sooner before the mod than it does now. It's much clearer overall.

Unless I'm using headphones, I always keep the iPod EQ on bass reducer mode. I can crank it much louder when playing through the speakers that way, and it even sounds better in my car (Just as an aside...I think the Aux input on my car's system has a limiter or something on it, and reducing the bass at the source and making it up with the car's EQ sounds much more open.... )

I know - I'm going to take the leap soon. I want to read up a bit on what to do once I jailbreak - this is a deep rooted fear. ;)

Dude! The only thing that will make it sound distorted is the act of recording/making a ringtone at too high a level. Poking holes in the grill have NOTHING to do with distorted sound. Poke the holes, for crying out loud....

good lk on the info i'll keep that in mind...know of any pics on this
I couldn't find the original picture that I posted but look at this one. The speaker is on the right in this picture. There is a protective film just inside of the speaker grill that has been removed from this picture.

Edited: It's picture #3 on the page.
