摘要： In a soundproof structure body including a tubular tube body having an opening portion, and a resonance type soundproof structure, in which a phase difference θ, at an upstream of the resonance type soundproof structure, between a reflected wave in the resonance type soundproof structure and a reflected wave of a transmitted wave transmitted through the resonance type soundproof structure and reflected by the opening portion satisfies Inequation |θ−π|≤π/3 with respect to a resonance frequency of the resonance type soundproof structure. This soundproof structure body can effectively offset a reflected wave from a resonance type soundproof structure body by opening end reflection by appropriately specifying positions of the resonance type soundproof structure and the opening end portion of a duct, a tube line, or the like to improve an absorbance of a single resonance type soundproof structure.

摘要： Provided are a partition member including a soundproof structure capable of efficiently insulating noise with a lightweight configuration, and an electronic device and a vehicle using the partition member.
In the partition member including the soundproof structure, the soundproof structure includes a support body having an opening, and a membrane-like member that is fixed to an opening surface of the support body in which the opening is formed and that vibrates as noise is incident, and a rear surface plate fixed to the support body on a side opposite to the membrane-like member, and the soundproof structure absorbs a sound by a resonance structure formed by a rear surface space surrounded by the rear surface plate, the membrane-like member, and the support body and the membrane-like member, and insulates a sound having a frequency higher than a relative maximum resonance frequency at which a sound absorption coefficient becomes a relative maximum among resonance frequencies of the resonance structure. The relative maximum resonance frequency is set to be lower than a sound insulation target frequency set for noise. Furthermore, in a case where the sound insulation target frequency is indicated as fn and the relative maximum resonance frequency is indicated as fr, fn/fr is 1.05 to 1.50.

摘要： A soundproof structure body includes a first tube structure and a second tube structure connected to the first tube structure and having a cross-sectional area different from the first tube structure, in which a structure body having a cross-sectional area smaller than a cross-sectional area of the first tube structure is installed in the first tube structure, and a transmission loss in a case where the structure body is installed in the first tube structure with respect to a case where the structure body is not installed in the first tube structure is positive at two frequencies adjacent to each other and difficult to generate an air column resonance mode in the first tube structure. This soundproof structure body generates a soundproof effect even at frequencies other than air column resonance of a tube structure such as a duct or a muffler, has a small size, and can obtain a high transmission loss in a wide-band.
