四川消声器厂家与(yu)您介绍各类型消(xiao)声器设(she)备的运行原理：

消(xiao)音器的(de)原理是它的(de)排气管(guan)是由两根不同长(zhang)度的(de)管(guan)子(zi)组成，先分开(kai)后会合(he)。由于(yu)(yu)两根管(guan)子(zi)的(de)长(zhang)度差等于(yu)(yu)汽车(che)发出声波波长(zhang)的(de)一半，所(suo)以两条(tiao)线声波在叠加干涉时相互抵(di)消(xiao)，减弱了声强(qiang)，降低了声音，从(cong)而达到(dao)消(xiao)音的(de)效果(guo)。

1.阻(zu)性(xing)消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)主要采用(yong)多孔吸声(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)来降低噪声(sheng)(sheng)(sheng)(sheng)。阻(zu)性(xing)消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)是通过将吸声(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)固定在气流通道(dao)的内壁上(shang)或(huo)以(yi)一(yi)定的方式设置在管道(dao)中(zhong)而(er)形(xing)成的。声(sheng)(sheng)(sheng)(sheng)波进入阻(zu)性(xing)消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)时，一(yi)部(bu)分声(sheng)(sheng)(sheng)(sheng)能在多孔材(cai)料(liao)的孔隙中(zhong)摩擦，转(zhuan)化为热(re)能消(xiao)(xiao)(xiao)散，削弱(ruo)了通过消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)的声(sheng)(sheng)(sheng)(sheng)波。电(dian)(dian)(dian)阻(zu)消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)就像一(yi)个纯电(dian)(dian)(dian)阻(zu)电(dian)(dian)(dian)路，吸声(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)类似电(dian)(dian)(dian)阻(zu)。因(yin)此，人们称这(zhei)种消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)为阻(zu)性(xing)消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)。阻(zu)性(xing)消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)对中(zhong)高频(pin)消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)效(xiao)果好，对低频(pin)消(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)效(xiao)果差。

2.反(fan)应消声器(qi)是(shi)由(you)带有突变界面的(de)(de)管道和室组(zu)成的(de)(de)，看起来像(xiang)是(shi)一(yi)个声学过(guo)(guo)滤器(qi)。类似于电(dian)(dian)过(guo)(guo)滤器(qi)，每一(yi)个带管的(de)(de)腔室都是(shi)过(guo)(guo)滤器(qi)的(de)(de)一(yi)个网孔，管内的(de)(de)空(kong)气质量相当于电(dian)(dian)感和电(dian)(dian)阻(zu)，称(cheng)为音质和声阻(zu)。气室中(zhong)的(de)(de)空(kong)气体积相当于电(dian)(dian)容(rong)，这就(jiu)是(shi)所谓的(de)(de)声顺。

类似(si)于电滤波(bo)器，每个带管(guan)的(de)(de)(de)腔(qiang)体都有(you)(you)(you)自己的(de)(de)(de)固有(you)(you)(you)频(pin)(pin)(pin)率(lv)(lv)。当(dang)各种频(pin)(pin)(pin)率(lv)(lv)成(cheng)(cheng)分的(de)(de)(de)声(sheng)(sheng)波(bo)进入..短管(guan)时(shi)，只有(you)(you)(you)部分频(pin)(pin)(pin)率(lv)(lv)接近..网(wang)格固有(you)(you)(you)频(pin)(pin)(pin)率(lv)(lv)的(de)(de)(de)声(sheng)(sheng)波(bo)才能通(tong)过(guo)(guo)网(wang)格到(dao)达第二(er)短管(guan)孔口，而其他(ta)频(pin)(pin)(pin)率(lv)(lv)的(de)(de)(de)声(sheng)(sheng)波(bo)无法通(tong)过(guo)(guo)网(wang)格，只能在小房间内来回反(fan)射。因(yin)此，我们将这种对声(sheng)(sheng)波(bo)具有(you)(you)(you)滤波(bo)功能的(de)(de)(de)结构(gou)称为(wei)声(sheng)(sheng)滤波(bo)器。通(tong)过(guo)(guo)选择合适的(de)(de)(de)管(guan)腔(qiang)组合，可以滤除(chu)部分频(pin)(pin)(pin)率(lv)(lv)成(cheng)(cheng)分的(de)(de)(de)噪声(sheng)(sheng)，从(cong)而达到(dao)消声(sheng)(sheng)的(de)(de)(de)目的(de)(de)(de)。该抗性消声(sheng)(sheng)器适用于消除(chu)中低频(pin)(pin)(pin)噪声(sheng)(sheng)。
