I want to be able to play sound effects outside from a Shuffle. I don%26#39;t want to do it through a radio. Is there a way, or a cable, that has the 3.5mm jack on one end and regular speaker wire on the other?
Answers:
No. The headphone (3.5mm) jack will not drive a large enough signal for you to hear through regular speakers. The signal used to drive headphones is very small, on the order of mV, because the speakers are so close to your ear, and thus don%26#39;t require much power. The loudness of sound goes down by the square of the distance, so if you double the distance between yourself and the sound source, the sound intensity will decrease by 4x.
When you take the output of an iPod and plug it into a radio, that signal is amplified by the radio in order for you to hear it. There are many boom-box type products available that your iPod can plug directly into, if you don%26#39;t want to go through a receiver or amp.
I hate to say it, but this is actually a good thing. If the iPod *could* drive regular speakers, the battery life would be horrible. No. But you can use *powered* speakers.
Powered speakers are the sort of speaker youd normally use with a computer. They plug into the computer (or in your case, an iPod) for the audio signal, and into the wall for power.
