Description

1one

Известный штучный звукопоглотитель, выполненный в виде открытого конуса из двухслойного пористого материала, не обеспечивает необходимого звукопоглощени .The known piece sound absorber, made in the form of an open cone of a two-layer porous material, does not provide the necessary sound absorption.

Цель изобретени  - более эффективное поглощение звуковой энергии.The purpose of the invention is more efficient absorption of sound energy.

Дл  этого предложенный штучный звукопоглотитель выполнен в виде открытого с одной стороны корпуса, например цилиндрической формы, имеющего внутреннее заполнение из двух слоев микропористого материала, из которых внутренний слой обладает высокой проницаемостью дл  высокочастотных звуков, а наружный - дл  низкочастотны.х, причем внутреннее заполнение имеет форму концентрически расположенных вокруг центрального конуса кольцевых клиньев, примыкающих друг к другу своими основани ми.For this, the proposed sound absorber is made in the form of an open on one side of the case, for example a cylindrical shape, having an inner filling of two layers of microporous material, of which the inner layer has a high permeability for high-frequency sounds and the outer one for low frequencies. the shape is concentrically arranged around a central cone of ring wedges adjacent to each other by their bases.

На чертеже показан предложенный щтучный звукопоглотитель.The drawing shows the proposed sound absorber.

Звукопоглотитель состоит из цилиндричесКОГО корпуса 1, внутри которого размещены конус 2 и кольцевые клинь  3 и 4, выполненные из двух слоев микропористого материала.The sound absorber consists of a cylindrical body 1, inside which is placed a cone 2 and annular wedges 3 and 4, made of two layers of microporous material.

Корпус с одной стороны закрыт матом 5, выполненным из тех же звукопоглощающих материалов.The housing on one side is closed with a mat 5 made of the same sound-absorbing materials.

С закрытой стороны к корпусу креп тс  петли 6, за которые звукопоглотитель подвешивают к потолку.On the closed side, hinges 6 are fastened to the casing, for which the sound absorber is suspended from the ceiling.

Предмет изобретени Subject invention

Штучный звукопоглотитель, включающий открытый с одной стороны корпус и внутреннее заполнение из двухслойного пористого материала , отличающийс  тем, что, с целью более эффективного поглощени  звуковой энергии, внутреннее заполнение им:еет форму концентрически распололсснных вокруг центрального конуса кольцевых клиньев, примыкающих друг к другу своими основани ми.A piece of sound absorber, including a housing open on one side and internal filling of a two-layer porous material, characterized in that, in order to absorb sound energy more efficiently, internal filling with it: it forms concentrically annular wedges adjacent to the center cone adjacent to one another mi
