消聲器的種類

消聲器概述

消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)(qi)的(de)種類很，但(dan)究其消(xiao)聲(sheng)(sheng)(sheng)(sheng)機理，又可以把(ba)它們(men)分為六種要的(de)類型(xing)，即阻消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)(qi)、抗(kang)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)(qi)、阻抗(kang)復合式消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)(qi)、微穿孔板消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)(qi)、小孔消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)(qi)和有消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)(qi)。

消聲器介紹

阻消聲器

要是利用孔(kong)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)材料來(lai)降低(di)噪聲(sheng)(sheng)(sheng)(sheng)(sheng)的。把吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)材料固在氣流通道的內壁上或按照方式在管(guan)道排列，就(jiu)了阻(zu)(zu)消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)。當(dang)聲(sheng)(sheng)(sheng)(sheng)(sheng)波進入阻(zu)(zu)消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)時，部分(fen)聲(sheng)(sheng)(sheng)(sheng)(sheng)能在孔(kong)材料的孔(kong)隙摩(mo)擦(ca)而轉化熱能耗散掉(diao)，使通過消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)的聲(sheng)(sheng)(sheng)(sheng)(sheng)波減弱。阻(zu)(zu)消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)就(jiu)象電(dian)(dian)學上的純電(dian)(dian)阻(zu)(zu)電(dian)(dian)路(lu)，吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)材料類似(si)于(yu)電(dian)(dian)阻(zu)(zu)。因此，人們就(jiu)把這種(zhong)消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)稱(cheng)為阻(zu)(zu)消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)。阻(zu)(zu)消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)(qi)對(dui)頻消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)遙(yao)(yao)遙(yao)(yao)、對(dui)低(di)頻消(xiao)(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)遙(yao)(yao)遙(yao)(yao)較差。(要應用于(yu)發(fa)電(dian)(dian)機機消(xiao)(xiao)(xiao)(xiao)(xiao))

抗消聲器

是(shi)由變界面的(de)(de)管(guan)(guan)和(he)室(shi)合(he)而(er)的(de)(de)，象是(shi)個(ge)(ge)聲(sheng)(sheng)(sheng)學(xue)(xue)濾(lv)波(bo)(bo)器(qi)(qi)，與電(dian)學(xue)(xue)濾(lv)波(bo)(bo)器(qi)(qi)相似，每個(ge)(ge)帶管(guan)(guan)的(de)(de)小(xiao)(xiao)室(shi)是(shi)濾(lv)波(bo)(bo)器(qi)(qi)的(de)(de)個(ge)(ge)網(wang)(wang)孔(kong)，管(guan)(guan)的(de)(de)空氣(qi)(qi)相當于(yu)(yu)電(dian)學(xue)(xue)上的(de)(de)電(dian)和(he)電(dian)阻，稱為(wei)聲(sheng)(sheng)(sheng)和(he)聲(sheng)(sheng)(sheng)阻。小(xiao)(xiao)室(shi)的(de)(de)空氣(qi)(qi)體(ti)積相當于(yu)(yu)電(dian)學(xue)(xue)上的(de)(de)電(dian)容(rong)，稱為(wei)聲(sheng)(sheng)(sheng)順。與電(dian)學(xue)(xue)濾(lv)波(bo)(bo)器(qi)(qi)類似，每個(ge)(ge)帶管(guan)(guan)的(de)(de)小(xiao)(xiao)室(shi)都有自己(ji)的(de)(de)固有頻率(lv)(lv)。當包含有各(ge)種頻率(lv)(lv)分的(de)(de)聲(sheng)(sheng)(sheng)波(bo)(bo)進入個(ge)(ge)短(duan)管(guan)(guan)時(shi)，只(zhi)有在個(ge)(ge)網(wang)(wang)孔(kong)固有頻率(lv)(lv)附近(jin)的(de)(de)某些(xie)(xie)頻率(lv)(lv)的(de)(de)聲(sheng)(sheng)(sheng)波(bo)(bo)才能(neng)通過網(wang)(wang)孔(kong)到(dao)達二個(ge)(ge)短(duan)管(guan)(guan)口，而(er)另外些(xie)(xie)頻率(lv)(lv)的(de)(de)聲(sheng)(sheng)(sheng)波(bo)(bo)則遙遙能(neng)通過網(wang)(wang)孔(kong)．只(zhi)能(neng)在小(xiao)(xiao)室(shi)來回反射，因此，我(wo)們稱這種對聲(sheng)(sheng)(sheng)波(bo)(bo)有濾(lv)波(bo)(bo)功能(neng)的(de)(de)結為(wei)聲(sheng)(sheng)(sheng)學(xue)(xue)濾(lv)波(bo)(bo)器(qi)(qi)。選取(qu)適(shi)當的(de)(de)管(guan)(guan)和(he)室(shi)進行合(he)．就可以濾(lv)掉某些(xie)(xie)頻率(lv)(lv)分的(de)(de)噪聲(sheng)(sheng)(sheng)，從(cong)而(er)達到(dao)消聲(sheng)(sheng)(sheng)的(de)(de)目的(de)(de)。抗消聲(sheng)(sheng)(sheng)器(qi)(qi)適(shi)用于(yu)(yu)消除、低頻噪聲(sheng)(sheng)(sheng)。
