Abstract: There is provided a soundproof structure which is light and thin, which has air permeability so that wind and heat can pass therethrough and accordingly no heat accumulates on the inside, and which is suitable for equipment, automobiles, and household applications. The soundproof structure has one or more soundproof cells. Each soundproof cell includes a frame having a through-hole through which sound passes, a film fixed to the frame, an opening portion configured to include one or more holes drilled in the film, and a weight disposed on the film. The soundproof structure has a first shielding peak frequency, which is determined by the opening portion drilled in the film and at which a transmission loss is maximized, on a lower frequency side than a first natural vibration frequency of the film of each soundproof cell and a second shielding peak frequency, which is determined by the weight and at which a transmission loss is maximized, on a higher frequency side than the first natural vibration frequency of the film, and selectively insulates sound in a predetermined frequency band centered on the first shielding peak frequency and sound in a predetermined frequency band centered on the second shielding peak frequency.

Abstract: A handwriting support device includes a half mirror; an image display surface; a writing surface, a virtual image of an image displayed on the image display surface being projected on the writing surface. In a case where a real object is inserted onto the writing surface, the image display control unit causes a non-display processed image to be displayed on the image display surface, the non-display processed image being obtained by at least a partial region, of a region of the first image corresponding to a vertically projected region of the real object on the writing surface, being subjected to non-display processing. In the handwriting support device, an image, which is a virtual image of the non-display processed image in which at least a part of an inside of the vertically projected region of the real object is non-displayed, is projected onto the writing surface.

Abstract: A soundproof structure has one or more soundproof cells. Each of the one or more soundproof cells includes a frame having a through-hole, a film fixed to the frame, and an opening portion configured to include one or more holes drilled in the film. Neither end portions of the through-hole of the frame are closed. The soundproof structure has a shielding peak frequency, which is determined by the opening portion of each of the one or more soundproof cells and at which a transmission loss is maximized, on a lower frequency side than a first natural vibration frequency of the film of each of the one or more soundproof cells, and selectively insulates sound in a predetermined frequency band including the shielding peak frequency at its center. Accordingly, there is provided a soundproof structure that is light and thin, does not depend on the position and shape of a hole, has high robustness as a sound insulation material, is stable, has air permeability, has no heat, and is excellent in manufacturability, and a soundproof structure manufacturing method.
