Homework Help: Homemade High-Quality Speakers

  1. Oct 30, 2009 #1
    1. The problem statement, all variables and given/known data
    We have to make a speaker with 4 rare earth magnets, and whatever materials we can buy or find . How to make the coil? What should we use for the cone of the speaker? Our ideas are to create a 5.1 or 2.3 surround sound speaker system with excellent mid-range sound quality.

    2. Relevant equations

    3. The attempt at a solution
    Using guides off the internet and materials from radio-shack to create the speakers.

    Did the assignment say the speaker had to be moving coil?
    Would it be easier to make if the magnet was moving?

    I don't know if this would work, but the bottom of some large soda drink containers is thin plastic, it is very strong and it is concave. If you supported the sides of this (after cutting it off the bottle) on soft foam and glued a magnet to the centre of it, maybe you could attract the magnet with a coil wound on some soft iron.
