歪み形磁気回路。 A pole top made of a magnetic plate is mounted on the center pole so as to cover the top surface of the center pole and the top surface of the conductive ring fitted on the outside thereof, and a magnetic gap is formed between the pole top and the pole top. In a device equipped with a top plate polymerized and fixed to a magnet on the bottom plate of the center pole, a hole is formed in the center of the top surface of the center pole and in the center of the pole top to position the conductive ring and the pole top. A low magnetostrictive magnetic circuit for a speaker unit, characterized in that fixing pins are press-fitted into both drilled holes.
