| 摘要 | An input device includes a first yoke; a substrate disposed on the first yoke; a coil disposed on the substrate; and a second yoke disposed above the coil and configured to be displaced downward by a force applied and thereby to change inductance of the coil. The input device is configured to output a signal corresponding to the amount of displacement of the second yoke. The substrate has an opening that communicates with a hollow of the coil, and the first yoke includes a step that is inserted into the opening of the substrate. | ||

| 主权项 | 1. An input device, comprising: a first yoke; a plate-shaped substrate disposed on the first yoke; a coil disposed on the substrate; and a second yoke disposed above the coil and configured to be displaced downward by a force applied thereto and thereby to change inductance of the coil, wherein the input device is configured to output a signal corresponding to an amount of displacement of the second yoke; the substrate has an opening formed therein that is disposed below a hollow of the coil and communicates with the hollow of the coil; the first yoke includes a step formed thereon that is inserted into the opening of the substrate; and the step passes completely through the opening of the substrate and is made of a magnetic material, and an upper surface of the step is lower than an upper end face of the coil. | ||
