Latest Patents

Minaga holds a patent for an electromagnetic electro-acoustic transducer. This invention is designed to generate an incoming indicator tone for mobile phones and similar devices. The transducer features a resin magnet composed of both hard and soft magnetic materials. By adjusting the compound ratio of the soft magnetic material, the lowest resonant frequency can be easily set. This innovation allows for a high magnetic flux density, which is achieved by increasing the magnetic permeability of the resin magnet. Consequently, this results in a smaller size and higher sound pressure due to an increase in the driving force exerted on the diaphragm. His patent is a testament to his ingenuity in enhancing mobile phone technology.
