LOUDSPEAKER

摘要

A loudspeaker includes a frame, a diaphragm, a magnetic circuit, a voice coil body, and a cover. The magnetic circuit includes a first surface facing a diaphragm, a second surface opposite to the first surface, a magnetic gap, a through-hole, and a first corner portion. The through-hole penetrates between the first surface and the second surface. The first corner portion has a first radius of curvature, and formed in such a manner as to extend over a section facing the through-hole and at least one of the first surface and the second surface. The cover has a second corner portion having a second radius of curvature larger than the first radius of curvature, and formed so as to cover at least a part of the first corner portion.
