can this be done?

we have a huge room/hall that seats about 1,000 and would like to put speakers in the room, but no electricity can be used. is there such a thing?
 
cardboard cones? 😀

Electricity drives speakers so not unless you had another power source.

thank you wise one.....you will get far in life 😀
 
LOL, ok I'm curious, is the no electricity thing for some bizarre scientific reason or for some bizarre religious reason?

You can't drive speakers without electricity... what would make them move in and out?? Your only option to create sound without electricity is to find another way of moving air, but there's no way to modulate it fast enough w/out some sort of eletrical power somewhere in the path.

You can surely put the speakers physically outside the room and provide a way for sound to get IN.. but I have a feeling this isn't what you're looking for.



 
Can you generate your own electricty?? (generator) Then use the electricity generated to power the speaker?
 
eh the old phonographs had that big cone like speaker that vibrated through physical contact with the grooves in the record, but the turntable still had to be turned somehow. So unless you want to peddle-turn an ancient phonograph and want to hear barely anything out of it...err no.

it's for religious reasons. the local temple wants to put speakers, but they cannot use electricity (no electricity can be used on the Sabbath).

I thought it could be used, but not switched on/off (the tiny spark is considering creating fire)...

im sorry but i think you might be SOL
 
hey, when did this quick reply box show up? Hehe, I always liked these on other forums....

Anyways....what if you use some sort of paper cup & string technique?

I still think your best bet would be good acoustics built into the room & to talk really loud.
 
Which part of physically impossible didn't you get? ;-)

What exactly do they want to broadcast through the speakers, that may be a better question. But if you can't "use electricity" then there are no lights? No publicly provided water? No fans?

what kind of sense does that make? did satan create electricity? can you use fire?
 
Even if there were speakers, how would you get audio to them without electricity? You need some sort of receiver or something that will surely take power. Will you not have electric lights or anything either?
 
If you can drive speakers with no electricity then theoretically you can create free energy right? The vibrations in the air could be used to generate energy.

:-/...can we maybe keep this a purly scientific thread meant to help someone out? I don't agree with the ideas either, almost kinda personally find them rediculous....but that's my own opinion. If they wanted to discuss that, make a new thread for it....but let's not try & ruin this one....
