    1、減振
    減振主要是盡量減少安裝揚聲器部位周圍的振動,因為揚聲器在工作時,音盆所產生的振動也會導致其周邊的鋼板部分也產生振動,從而使音盆振動產生非線性失真,影響整體音質。減振的方法一般是用固定法進行減振,就是在門板的內側,貼覆硬度較大的減振板如膠板等。在揚聲器的安裝部位,單純地利用表面來增加剛性還不夠,最好是加裝剛性較好的墊圈。在較高級的改裝中,將門板重新倒模,增加其剛性。
    To minimize vibration damping mainly around the mounting portion of the speaker, because the speaker is in operation, the vibration generated by the cone plate can also cause it to vibrate also part of the periphery, so that the vibration of the cone of nonlinear distortion, to affect the overall quality . Vibration damping method is generally carried out using a fixed method, that is,on the inside of the door, and paste the cover hardness greater vibration plate such as sheet and so on. In the installation position of the speaker, simply by the surface is not enough to increase the rigidity, it is preferable to install more rigid washers. In more advanced modification, the door re-inverted mode, increasing its rigidity.
    2、隔音
    由于汽車的特殊性,汽車門板的處理在減振的同時,也要做相應的隔音處理,隔音是隔絕汽車的外界噪音以及在行駛途中的引擎聲,路噪和風噪聲等。隔音的方法是降低固體噪聲的傳入,一般地在減振的材料中,會采用雙層的材料同時做到吸聲隔音的處理,同時在引擎艙蓋,防火墻等處都可以貼覆減振材料等。而要濾除由空氣中傳來的噪聲,在汽車環境中,比較難以處理。一般只能對汽車的密封性做處理,也就是對汽車的橡膠邊條做良好的處理,特別是在改裝過程中反復拆除,會使其密封性不好。
    Due to the particularity of the car, the car door handle in damping, but also to do the appropriate handling noise, noise is isolated from outside noise as well as a car engine sound in a moving way, the road noise and wind noise. The method is to reduce the noise of the incoming solid noise, vibration damping materials in general, the use of double material will be acoustic noise while handling, while the engine hatch, firewalls, etc. can be affixed to cover damping materials. And to filter out the noise coming from the air, in the automotive environment, the more difficult to deal with. Generally only do the deal on the tightness of the car, which is on the edge of automotive rubber doing a good deal, especially in the conversion process is repeated demolition, sealing will make it bad.
    3、密封
    由于前聲場的車門就如同音箱的箱體,所以要求門板的密封性非常好。汽車車門上有眾多的維修孔,如果沒有處理,就會使揚聲器的背面所發出的相位相反的聲音與前面的聲音相干涉,特別使波長較長的低頻衰減嚴重。如果門板處理不好,就會使良好的低頻響應的頂級套裝的聲音大打折扣。在改裝前聲場時,密封的處理方法是利用鉛板或鋁板等將維修孔封閉,并將所有的部分全部用膠密封處理良好。這樣可使低頻下潛延伸更低,產生良好的控制力,聲音清晰度加強。
    Since the doors before the sound field as if the speaker cabinet, so they requested that the door seal is very good. There are numerous car repair holes on the door, if not dealt with, it will make the phase on the back of the speaker's voice issued contrary to interfere with the sound of the front, especially the low-frequency attenuation wavelength longer serious. If the door is not properly handled, it will make a good low-frequency response of the top suite of voice greatly reduced. When the sound field before conversion, sealing approach is the use of stereotype or aluminum, etc. will repair the hole closed, and all of the part of all well sealed with glue. This allows low dive extend lower, resulting in good control, sound clarity enhanced.
