| titleOfInvention | Magnetic circuit for speaker, method of manufacturing the same, and speaker using the same |
| abstract | A magnetic circuit for a loudspeaker capable of obtaining a sufficient sound pressure while reducing the thickness of a magnetic circuit itself without changing the thickness of a plate and a magnet, a method of manufacturing the same, and a loudspeaker using the same. . A plurality of slits (3, 4) are formed in parallel on the surface of a rectangular bonded magnet composition (2), and the magnetic flux of each slit (3, 4) is always in the opposite direction. Are magnetized to form a bond magnet, and pole pieces 5, 6 and 6, 7 are arranged and fixed on the surface of the bond magnet from both sides along the slits 3 and 4, respectively. The gap formed between the slits 6 and 7 is positioned on the center of each of the slits 3 and 4 to produce the speaker magnetic circuit 1 as the magnetic gaps 8 and 9. Get a speaker.
