LOUDSPEAKER

摘要

A loudspeaker is provided with a frame, a diaphragm, a magnetic circuit, a voice coil body, and a cover. The magnetic circuit comprises a first surface that faces the diaphragm, a second surface on the opposite side from the first surface, a magnetic gap, a through hole, and a first corner section. The through hole passes through the interval between the first surface and the second surface. The first corner section has a first radius of curvature and is formed so as to extend to at least one of the first surface and the second surface and to a location that faces the through hole. The cover comprises a second corner section having a second radius of curvature that is larger than the first radius of curvature, and said cover is formed so as to cover at least a part of the first corner section.
