i need to know the basics to create a proper coil for my speaker , can anyone help by posting what i should know b4 creating one?

 

How much do you know of electric and magnetic field effects? That would be a good start on the basics...

 

Simply put, real simply put, How do speakers work? That is a very basic overview. What you have not mentioned is how much power do you expect this speaker to handle? That will be a part of determining the coil wire gauge you wind your voice coil with. You also make no mention of core size? Material? Frequency response and the list continues. I suggest simply researching speakers in some detail to where you gain enough understanding as to why speakers work and how they work.

A speaker is conceptually very simple- a moving coil in a magnetic field that drives a paper cone.

In practice, however, it would be really hard to build a decent one without high-level maker skills.
The mechanical structures you need to build require high tolerances and specialized materials.

 

The magnetic gap in a speaker's magnet structure will be very difficult to make narrow but still allow the voice coil to move in and out of it without rubbing.
The spider that keeps the parts from rubbing will also be difficult to make.

The brushless motors in my electric radio controlled model airplanes play a little tune when they are initialized, and they scream loudly for a moment when overloaded before being cutoff.
