Japanese Patent JP7176701

B2

[Problem] To provide a transducer capable of ensuring a sufficient amount of displacement in xy-plane directions while maintaining a constant distance between a magnet structure and a circuit board. [Solution] This transducer is provided with: a magnet structure 10 including a magnet 11 having a north-pole magnetic pole face and a magnet 12 having a south-pole magnetic pole face; a circuit board 20 having wires 21, 22 formed thereon; a first sliding mechanism for causing the magnet structure 10 and the circuit board 20 to slide in the x-direction; and a second sliding mechanism for causing the magnet structure 10 and the circuit board 20 to slide in the y-direction. In the magnet structure 10, the magnets 11, 12 are arranged in a matrix form. The wire 21 crosses the magnets 11, 12 in the y-direction, and the wire 22 crosses the magnets 11, 12 in the x-direction. According to the present invention, two-dimensional operations of the circuit board 20 and the magnet structure 10 can be performed smoothly, and a sufficient amount of displacement can also be ensured. In addition, since an elastic hinge and the like are not used, deformation in the z-direction does not occur.
