How about investing your money it in the BANK? or at least Apple shares? since you are sooo in love with S.J.

And you can always buy an iPhone, then pay the ETF then go prepaid... F- the contract!

- and in this case - invest in whatever makes you feel happier or better about something, here the iPhone..

It's like buying new rims for your car, most likely it won't make it worth more money, but it might make you like it better - and thus it's been a good investment.
Sometimes I even buy pants that cost over $150, even if there are fine $20 alternatives to choose from. Why your dad might ask? Because I liked those specific pants, and they make me feel good when wearing them.

If the word 'buy' or 'have' (or anything else that could have fit in there and made sense) began with an 'i', I would have used that.

The soundwaves may be focused (what I think you mean by concentrated), but the waves are still going to radiate in all directions once they leave the mechanical amplifier chamber. The sound is still being spread out over the same volume of space.

The point is, it's the same amount of overall energy. There is no amplification of any signals anywhere. Yes, it'll spread out over the same volume of space, but it will be far more uneven. The "cupping my hands around my mouth" example is the same thing. More of the equal energy radiates in one axis than the others.

It's still not amplification.]]>Sep 17th 2008 10:47PMhttp://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/http://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/

Since the horn acts as a resonating chamber, the efficiency of the speaker is increased. A more efficient speaker produces a greater sound pressure level than a less efficient speaker. The greater sound pressure level is interpreted by the listener as being louder, and the sound can be said to have been amplified. I think our impasse results from differing ideas of whats being amplified. I agree that no electrical watts are being added, but acoustic watts (determined by the efficiency of the driver) certainly are being increased.

Just like the resonating hollow body of a guitar sounds louder than a solid-body guitar.

I did look up audio concentrators, and it seems like the government has some interesting conceptual applications, like identifying materials inside closed containers.]]>Sep 18th 2008 7:18PMhttp://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/http://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/Sep 17th 2008 11:00PMhttp://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/http://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/Sep 18th 2008 4:16PMhttp://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/http://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/
It is the exact same amount of energy. The iPhone doesn't suddenly get more power just because the speakers are concentrated into a chamber. If it actually did create more energy passively, then you'd better patent that idea quick.

"The amplitude of the soundwaves is (supposedly - I've not done any first hand testing) increased by the design of the wave guide."

On that axis, yes, it's louder (that's the point of concentrating the energy), but it's quieter on all other axes. The overall amount of energy expended is exactly the same. Actually, it's slightly less due to small absorbtion of sound energy. ;-)

"If the sound produced is louder, most people would agree that the sound has been amplified."

It's still not amplification, no matter who agrees with the example. If most people say that the moon is made of green cheese, that wouldn't make it true. ;-) The problem is most people don't understand the difference between amplification and concentration, this example being the latter. The prior example posted by someone else WRT transmission lines also made no mention of amplification. The guitar example is also well intentioned but wrong. There is no amplification occurring. Taken from Wikipedia on "Acoustic guitar":

"An acoustic guitar is a guitar that uses only acoustic methods to project the sound produced by its strings. "

Complete lack of mention of the word "amplification" or "amplify". In fact:

"No amplification actually occurs in this process, in the sense that no energy is externally added to increase the loudness of the sound " And "The function of the entire acoustic system is to maximize intensity of sound, but since total energy remains constant,".

And no, I didn't write that. ;-) I just have a very good understanding of sound, and I hope this has been educational.]]>Sep 18th 2008 12:07AMhttp://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/http://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/Sep 18th 2008 5:18AMhttp://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/http://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/Sep 18th 2008 2:05AMhttp://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/http://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/Sep 18th 2008 5:26PMhttp://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/http://www.engadget.com/2008/09/17/griffin-unveils-aircurve-acoustic-amplifier-clarifi-case-for-ip/
Brilliant so now engadget has become nothing more than a typical forum, with random know-it-alls posting about things.

It amplifies the sound, thats how waveguides work. You can use a waveguide as a filter or as a physical sound amplifier.
