  • Publication number: 20200161038
    Abstract: In the actuator, the first end plate part of the first cover member in the support body is layered on one side in the first direction of the holder and faces the first yoke of the movable body from one side in the first direction. The second end plate part of the second cover member in the support body is layered on the other side in the first direction of the holder and faces the movable body from the other side in the first direction. Thus, the first viscoelastic member interposed between the movable body and the first end plate part in the first direction properly contacts with the movable body and the first end plate part. The second viscoelastic member interposed between the movable body and the second end plate part in the first direction properly contacts with the movable body and the second end plate part.

  • Publication number: 20200161954
    Abstract: In a magnetic drive circuit of an actuator, a first yoke and a second yoke are disposed on both sides in a first direction across a coil, and a first magnet and a second magnet are fixed to the first yoke and the second yoke. The first yoke includes a first connecting plate part and a second connecting plate part that extend toward the second yoke. Thus, welding of the first connecting plate part and the second yoke and the second connecting plate part and the second yoke can be efficiently performed on a different side in the first direction (a side where the second yoke is located).

  • Publication number: 20200161955
    Abstract: In the actuator, the viscoelastic members are arranged at positions at which the support body and the movable body face each other in the first direction, and the magnetic drive circuit drives the movable body in the second direction which crosses the first direction. The viscoelastic members connect the movable body and the support body together while having the thickness direction thereof in the first direction and extending in the second direction. Therefore, resonance caused when the movable body is vibrated can be restricted. Reproducibility of vibration acceleration corresponding to the input signals can be improved by utilizing the spring elements of the viscoelastic members in the shearing direction, thus enabling the actuator to vibrate with delicate nuances. Further, the viscoelastic members can be prevented from being pressed in the thickness direction and greatly deformed, therefore, preventing the gap between the movable body and the support body from greatly varying.

  • Publication number: 20200142489
    Abstract: An input device (100) has an input unit (1) provided with a touch panel (13), a frame (2) that surrounds the outer periphery of the input unit (1), and an actuator (3) that causes the input unit (1) to vibrate in the X direction. The input unit (1) and the frame (2) are configured such that even if the relative positions of the frame (2) and an outer periphery (5), which face each other in the in-plane direction of the touch panel (13), were to change due to the vibration of the input unit (1), this change tends not to be perceived as a visual change by a user, making it difficult to perceive the movement.
