Latest Patents

Makihata’s listed patents address protection and performance in microphone designs.

“Shield case and MEMS microphone having it” describes a shield case for protecting an MEMS chip mounted on a board. Its side plates are thicker than its top plate, allowing a larger top-plate area while preserving space for a gasket. This design aims to support airtightness without changing the conventional chucking area.

“Heat-resistant electret condenser microphone” describes a microphone case coated with a material that conducts heat less effectively than metal and withstands temperatures above 260°C. The coating is intended to reduce heat transfer to the microphone’s interior and help protect its function during brief exposure to high temperatures, such as reflow soldering.
