Magnetic field coil ferrous material for loudspeaker

[QUOTE="Baluncore, post: 6866577, member: 447632"] I have experience with that type of electromagnet, but not with ones as small as that. Maybe prototype by replacing only the magnet on a standard speaker. Will you use a commercial product for the voice coil and for the cone and suspension? You should start by specifying the voice coil dimensions, the radii and the axial length of the winding, as everything will grow from that by geometry. Maintain the same section of magnetic path throughout the magnetic circuit, taking into account the circumference at different radii. Avoid sharp internal corners. [/QUOTE]
