Vibration generating device with fixed case with first outer and inner cylinders and second cylinder attached to end of first outer cylinder
12627208 · 2026-05-12 · ·

A vibration generating device including a fixed case including a tube extending in a first direction; a coil attached inside the tube; a movable body arranged inside the coil and including a magnetic field generator configured to generate a magnetic field toward the coil; and a support member interposed between the fixed case and the movable body and supporting the movable body inside the coil such that the movable body is configured to vibrate in the first direction. The fixed case includes a first fixed case member including a first outer cylinder and an inner cylinder extending from the first outer cylinder along the first direction, and a second fixed case member including a second outer cylinder attached to an end of the first outer cylinder to cover the inner cylinder. The coil is wound around the inner cylinder and covered by the second outer cylinder.
