okay…i think i’ve been on my computer too long…my speaker’s are talking to me!
I swear I’m telling the truth. Sometimes I’ll be sitting here working on the computer when I hear something. The TV and radio are both off. I get up and look outside…nothing. I come back and can still hear it. I pick up my speaker’s and hold them to my ear and I can hear people talking. Sometimes it sounds like people talking on a CB radio…sometimes it sounds like a tv show of some kind…tonite it sounds like a preacher giving his sermon with a mexican guy translating it along with him.
Either my speaker’s are picking up some kind of signal or I have a wire loose somewhere!

**Teet, you need to back away from the computer and go get some rest.
Actually it’s happened with my phone, I pick up on other conversations all the time. **
OH CRAP! I was talking to my friend on my cell phone one time (she was on a cell phone too) when I heard someone pick up a phone, thru the phone! Then I heard them dial, I heard the ring, and I heard them talking in another language (they sounded Indian from their accents). It was insane! I never had anything like that happen on a cell phone before… weeeeeird…
oh and about the speakers… yeah that happens too. My g/fs speakers will pick up any signals in the area if they are at a high enough elevation. She was getting the spanish channel on her speakers…
Are you using Windows XP? I don’t know why, but sometimes, I’d be offline working on some stuff and magically, the speaker plays some advertisement for like, body part enlargement stuff, really scary. But once I turned off some services in XP, it fixed it all. As for phone, I remember when our phone line was cut, when it was being restored, I could hear in on other phone calls in the neighborhood but I can’t talk to them. They where gossiping. :+)
Any metalic object can pick up radio signals. As soon as you have a wire or anything else in the presence of a fluctuating magnetic field it’ll induce a current in the wire according to the rate of cutting flux (flux is a measure of magnetic strength) similarly you can induce a current in a wire with a static magnetic or electromagnetic field by moving the wire back and forth.
Its been heard of people picking up radio signals in the fillings in their teeth, opening their mouths would act to amplify the oscillation to an audible level, I’ve built a radio (using a kit) that didn’t have a power supply using this princlple. During my uncle’s funeral the pa system picked up the radio signal of a passing cab much to the annoiance of the priest giving the sermen at the time.
Transformers working with ac current also use this principle to step down the output current. When you plug in a transformer the outputted current isn’t actually physically connected to the input supply with any wireing. Instead there’s a primary coil and a secondary coil, the input current travels through the primary coil and induces current in the secondary coil. The ratio of size of primary to secondary coil determins the magnitude of the output current.
If your speakers are self amplified its probably a tiny current being induced by local radio signals being amplified by your er… amp.
Theres a load of useless info you didn’t want to know! Sorry I’m trying my best to forget my brief encounter with degree level physics
