The thing is when volume is on full and I'm watching a movie or something else(for example the startup sound) There's a weird buzz/rattle thing during especially loud, high pitched parts (explosions or whatever). It could be the case or something inside rattling,buzzing. supposingly something in the keyboard or speakers but not maybe speakers because when i press the keyboard with my hand hard enough but not too hard :) ,the buzzing/rattling sound does not occur.
The sound comes as if from the top right corner of the keyboard. Anyone knows what's wrong and has some knowledge how to fix it? thx
 
The ibooks used to do that when metal shavings got attached to the cone of the speaker. Blowing the speaker with compressed air usually cleared it up.
 
yeah but i can hear that something in the keyboard, under the keyboard is very loose
 
or have you guys a feeling that it's caused by the lack of bass in internal speakers? that they produce harsh poor sound when playing loud?
 
I'm so clumsyy dude. I'm just afraid to do that. What's particular under the keyboard in the top right corner beacuse this is the place the rattling sound comes from I guess
 
The speakers are just okay on these computers; spend some money and get good headphones ;)
 
I have just carried out a test. I played a youtube clip ( volume max) and the speakers make a buzz/rattling sound. then a pluged in my headphones and the volume was very loud at the middle of volume scale. when i played my headphones on max volume i could then hear rattlin/buzz sound. IS it ok that those internal speakers are just some kind of insufficient? that they play the music not so loud at their full power?as if they suffocate? by taking so much power at the same time playing silent? hhe
 
By listening to a youtube clip, with all your volume levels turned up to full, you're over-driving the amp and clipping (waveform distortion) is the end result. The resulting distortion, combined with over-volting, could easily burn out the coils of your tiny little speakers in the Macbook.

The Macbook isn't a boombox, it's a laptop. It's not designed to fill up a room with sound, e.g., don't expect 85-95 dB SPL, which is about what an average home stereo might be able to produce.

General rule of thumb: If it sounds like pure crap, turn down the volume until it sounds "clean".
 
what about the speaker under the keyboard ? does he make the keys vibrate and rattle when there is a loud sound?
 
if you care soo much about it, take it to an apple store and have them take a look. and just for the record, my macbook, almost 1 year old, doesnt make a rattling sound or any kind of distortion while playing youtube or heavy bass mp3 clips or anything. I think you have a defected speaker, since I just tested mine and it works flawlessly. and do try not to blast those tiny speakers, its not a home stereo as someone already said.
 
Is it under warranty? If so why dont you try taking it to your local apple store/service provider?
