Abstract
A speaker and a magnetic circuit for a speaker, in which the high quality sound is obtained, are provided using a structure which is thin, light-weight and symmetrical in the vibration direction. In three sheets of layered magnets 11, 12 , and 13 , the first magnet 11 of the first layer and the third magnet 13 of the third layer are arranged in the magnetic directions which repel each other, and the polarity of second magnet 12 of the second layer is arranged perpendicularly to the polarity of the first and third magnets 11 and 13 of the first and third layers at the top and bottom thereof. A voice coil 19 wound near the center of a voice coil bobbin 18 is arranged to oppose the second magnet 12 of the second layer of the magnetic circuit composed of the three layers, and the same vibration systems composed of the diaphragms 14, 16 and edges 15, 17 are connected to both the ends of this voice coil bobbin 18 . Accordingly, the speaker 10 which has a vibration system that is symmetrical with respect to a center axis X-X perpendicular to the direction of a center axis of a voice coil is obtained.
