Claim 0:
1. A magnetic circuit structure of a transducer, wherein the magnetic circuit structure comprises a static magnetic field generating device, the static magnetic field generating device comprises magnet sets,
wherein the magnet sets comprise a first magnet set that is magnetized in a moving direction of the transducer, a second magnet set that is located in a direction orthogonal to a static magnetic field generated by the first magnet set, and a third magnet set disposed in a direction orthogonal to static magnetic fields generated by the first magnet set and the second magnet set, and
wherein a magnetization direction of the second magnet set is orthogonal to a magnetization direction of the first magnet set, a magnetization direction of the third magnet set is orthogonal to the magnetization directions of the second magnet set and the first magnet set, and the second magnet set and third magnet set are provided to increase magnetic induction intensity of the static magnetic field.
