An Invention – Computer Speakers are sensitive than a mobile !

I don’t know if its actually of any use but I need to post this in order to get your views and ideas on the same because it does help us in enhancing our concocting skills.

I had my cell kept near to my computer speakers which were obviously switched on. Whenever someone calls up, a disturbance with a peculiar sound in the speaker is produced exactly 3-4 seconds before the cell actually starts ringing.

Now we can capture this disturbance produced in the speaker with a suitable instrument that is in turn connected to an LED or an alarm. Well, whenever someone will call up, the LED will glow or the alarm will ring just 3 seconds before the cell actually starts ringing. This means we have come out with an invention of a device 3 seconds more sensitive than our cell phone.

I know 3 seconds are of no use. Anyways, the cell will do ring after 3 seconds and we can attend the call. So, whats the big deal ? Well, in the world of technology even a milli-second matters and we are on the road to competition !!

Please let me know about your views and ideas by posting in the comments section.

How come you are so sure that every time your speakers react your phone will ring? What if that's somebody else's call? Also, I would find it more probable that thing you hear in speakers is actually your phone reply to a signal you do not hear in speakers.

What does this idea have to do with astronomy or space science?

no big deal. when i'm at home i set my cell under the front of my monitor (it's the only space that's clear on my desk that isn't designated for snacks or beer ) my monitor will flicker a second before the phone actually starts ringing. it's a blackberry so it also flickers when I have my messenger service active and it pings the server. it's just interference.

As to your "invention", what is the usefullness of it? It will allow people to answer thier phones before the first ring? as mentioned this seems to be caused by your phone's "connect call/send data" process rather than the incomming signal. so until that connection is made you cannot answer anyway (or at least, that would be my guess).

lastly, this is not "against the mainstream". It's more of a random observation that (if it belongs anywhere) would be more "off topic babbeling".

I've had the same thing happening with PC speakers, audio system, and -very interesting sound effect!- an electronic organ, and some other equipment. It's very standard for a cell phone to give pre-ring interference.

Yes, you know a few seconds before the phone rings that you will get a call. BUT the call is only ready to be answered when the phone starts ringing (a phone knows it's getting a call a small time before everything is ready to actually set up the two way connection), so the only advantage it would give is to get your phone ready and wait for the first ring. But other than that, you can't start talking sooner.

It's been done. I used to see vibrating belt clips for cell phones that would be activated by an incoming call to the phone.

I don't think they're around much any more, since virtually all cell phones have a built-in vibrate function now.

PS: I have a mount on the dashboard of my car so that I can clip my phone to the dash while I'm sitting in the car. If a call comes in when I'm playing my mp3 player through the tape deck, I get static. Not if I'm just listening to the radio, though.

It happens sometimes that I hear this typical sound (which resembles a liitle bit the sound of old computer programs, which I think has to do with the baud-rate), but my phone won't ring. I always assumed that my phone is tuning in on the network then. Is that correct?

Something like that. That's another instance where I've noticed interference (along with incomming calls or outgoing/incoming chat messages). also clock updates. anything that requires an outgoing signal.

Yes that's correct. When I switch on a Belgian cell phone in the netherlands, it has no network. After a few seconds (half a minute) I get this thud thud thud interference when it finds a Dutch network.

But indeed anything requiring an outside connection will be able to cause the interference.

Well, they do sell tiny stickers with cute designs and LEDs in them that you can attach on or near the phone, and these will flash when the phone rings and when the phone is connected. I guess they are powered by the EM emitted by the phone when it is transmitting.

Now, it isn't right to say that the speakers are more sensitive, as the interference is caused by the phone answering transmitting replies to the base station it is connected to, so the phone is already aware of whats going on. Also, the phone and base stations will communicate for other reasons than recieving calls or messages, so you may experience interference without it ringing.
