  • the gel-like damper member 70 is fixed to both the movable body 4 and the support body 5 by a method such as adhesion.
  • the configuration of the actuator 1 can be simplified.
  • the gel damper member 70 has a penetration of 90 degrees to 110 degrees. For this reason, the gel-like damper member 70 has sufficient elasticity to exhibit a damper function, and it is difficult for the gel-like damper member 70 to break and scatter.
  • the gel-like damper member 70 is disposed between the support 5 and the movable body 4 on both sides of the movable body 4 in the first direction L1. For this reason, when the movable body 4 moves in the first direction L1, the gel-like damper member 70 is always compressed and deformed on one side or the other side of the first direction L1, and on the other side, Extends in the thickness direction (axial direction). As described above, the gel-like damper member 70 has more nonlinear components than the linear components in the expansion and contraction characteristics at the time of compression. Therefore, when the movable body 4 moves in the first direction L1, the gel-like damper member 70 must be in the compression side. The damper member 70 is compressed according to a non-linear expansion / contraction characteristic. Therefore, it is possible to avoid a large change in the gap between the movable body 4 and the support body 5, and to secure a gap in the first direction L1 between the movable body 4 and the support body 5.
  • the gel-like damper member 70 is deformed in a direction (shear direction) orthogonal to the thickness direction (axial direction) when the movable body 4 moves in the second direction L2 and the third direction L3.

And a direction parallel to the direction in which the movable body 4 vibrates. Therefore, the actuator 1 uses the deformation characteristics in the shear direction of the gel-like damper member 70 when the movable body 4 is vibrated in the second direction L2 and the third direction L3. The deformation characteristic in the shear direction of the gel-like damper member 70 has more linear components than non-linear components. Therefore, vibration characteristics with good linearity can be obtained in the driving direction of the actuator 1 (second direction L2, third direction L3).

Abstract

La présente invention concerne un actionneur capable d'amener un corps mobile à vibrer dans une pluralité de directions. Par exemple, un actionneur (1) présente un corps de support (5), un corps mobile (4), et un corps de raccordement (7) relié au corps mobile (4) et au corps de support (5). En outre, un premier circuit d'entraînement magnétique (10) est configuré entre le corps de support (5) et le corps mobile (4) et est pourvu d'un premier aimant (11) et d'une première bobine (12) qui s'oppose au premier aimant (11) dans une première direction (L1). Le premier circuit d'entraînement magnétique (10) génère une force d'entraînement qui entraîne le corps mobile (4) par rapport au corps de support (5) dans une deuxième direction (L2) orthogonale à la première direction (L1). En outre, un deuxième circuit d'entraînement magnétique (20) est configuré entre le corps de support (5) et le corps mobile (4) et est pourvu d'un deuxième aimant (21) et d'une deuxième bobine (22) qui s'oppose au deuxième aimant (21) dans la première direction (L1). Le deuxième circuit d'entraînement magnétique (20) génère une force d'entraînement qui entraîne le corps mobile (4) dans une troisième direction (L3) orthogonale à la première direction (L1).
