O Utility Model Registration Claim 1: A cylindrical outer magnet, a cylindrical or cylindrical inner magnet located concentrically inside the outer magnet, and closely attached to the rear surfaces of the outer magnet and inner magnet to hold them together. a circular plate-shaped force that is in close contact with the front surface of the outer magnet, a front outer yoke that is in close contact with the front surface of the inner magnet, and a circle that is in close contact with the front surface of the inner magnet and forms a magnetic gap in which the voice coil can fit between the front outer yoke and the front outer yoke; 1. A magnetic circuit device comprising a front inner yoke having an annular plate shape or a disk shape, and in which the polarity of the front and rear surfaces of the outer magnet is opposite to the polarity of the front and rear surfaces of the inner magnet. 2. The magnetic circuit device according to claim 1, wherein the strength of the magnetic poles of the inner magnet is approximately equal to the strength of the magnetic poles of the outer magnet. The brief description of the drawing has been amended as follows. "Speaker magnetic circuit device" on page 8, line 2 of the specification is corrected to "magnetic circuit device.""Magnetic circuit device for speakers" on page 8, line 6 of the specification is corrected to "magnetic circuit device for speakers, etc."
