Abstract
PURPOSE:To reduce the sound pressure distortion of a speaker by making magnetic alloy rings by reducing the crystal grains of an iron-nickel alloy through suitable fabrication such as bending, etc., and relieving residual stress through heat treatment at optimum temperature to linearize minor loops, and mounting the rings thus made to the speaker.
