Latest Patents
One of Sekine's latest patents is a sound reproducing apparatus. This innovative device features an ear-hole open type design that utilizes a bone conduction system to deliver high-quality sound across a wide frequency range. The first equalizer in the apparatus effectively removes high-range components that are challenging for vibration speakers to reproduce. This design minimizes sound leakage while allowing the vibration speaker to output sound effectively in the low to middle range. Additionally, a second equalizer is employed to filter out low to middle range components, enabling an air conduction speaker to produce high-quality sound in the high range.
Another significant patent is a track jump apparatus designed to stabilize the movement of an objective lens in disk drive systems. This apparatus includes a detection section that monitors the direction of the lens during tracking operations. A discrimination section then determines the direction of the track jumping operation. By coordinating these movements, the track jump is stabilized, ensuring that it is not adversely affected by the lens's tracking movements.
