can this actually work like a speaker?

Question

i hosted an image of the diagram on the link below just follow it and you'll be able to answers my question
and if theres something qrong with my design then tell me what

i heard you need resistance for this to work how many ohms do you need
(or at least recommended)

okay then what's the simplest way i can amplify the sound

alright so now i know it will produce sound
(very little sound) will any of these sound amplifyers help

Answer 1

8 ohms is standard house audio speaker. 4 ohms for car stero. Check the resistance of your speaker and make sure it has at least that.

Technically your design would work. But whether it would work to a level that your ears would be able to detect is another question.

Answer 2

Could work. Make sure you have enough resistance so you don't burn up the amplifier.
It is not a very efficient design (won't be loud) If you haven't torn open a real speaker, do it for fun. They wrap the coil around the magnets in a very tight but free to move cylinder.

Answer 3

That is a crude approximation of the core of a speaker. Basically, the cone is attached to the magnet and the cone interacts with the air, making the sound. Since there is no cone this would be very quiet, like trying to listen to a recordplayer by the sound of the actual needle. It can be done; that's how they were invented.

Answer 4

Something similar to your diagram should work as a loudspeaker, but make sure the coil is close to the magnet. If you look at a commercially-manufactured loudspeaker, you'll see how simple it is; just a permanent magnet and a moving coil fixed to a cardboard cone, which is basically what your diagram shows.

Answer 5

its worth a try dont put too much resistance on it and burn your house down =]
