Title: Yuhei Yamagishi: Innovator in Vibration Technology

Introduction

Yuhei Yamagishi is a prominent inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of vibration technology, holding 2 patents that showcase his innovative approach to device design.

Latest Patents

One of Yamagishi's latest patents is a vibration device that features a diaphragm and multiple piezoelectric films arranged at specific intervals. These films face the diaphragm and extend parallel to a second direction orthogonal to the first. The diaphragm is designed with at least one slit, dividing it into distinct regions. Each piezoelectric film is fixed to a corresponding region of the diaphragm, maintaining a tensioned state. When a voltage is applied, the films expand and contract in a planar direction, creating vibrations.

Another notable patent is a vibration device and tactile presentation device. This invention includes a diaphragm with a perimeter, a film that expands and contracts in a planar direction upon voltage application, and electrodes on each main surface. The diaphragm has a first region at a node of vibration and a second region elsewhere. The wire extends from the second region toward the first or from the first region outside the diaphragm's perimeter, enhancing the device's functionality.
