    1、减振
    减振主要是尽量减少安装扬声器部位周围的振动,因为扬声器在工作时,音盆所产生的振动也会导致其周边的钢板部分也产生振动,从而使音盆振动产生非线性失真,影响整体音质。减振的方法一般是用固定法进行减振,就是在门板的内侧,贴覆硬度较大的减振板如胶板等。在扬声器的安装部位,单纯地利用表面来增加刚性还不够,最好是加装刚性较好的垫圈。在较高级的yabo亚博体育苹果下载中,将门板重新倒模,增加其刚性。
    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
    由于汽车的特殊性,汽车门板的处理在减振的同时,也要做相应的隔音处理,隔音是隔绝汽车的外界噪音以及在行驶途中的引擎声,路噪和风噪声等。隔音的方法是降低固体噪声的传入,一般地在减振的材料中,会采用双层的材料同时做到吸声隔音的处理,同时在引擎舱盖,防火墙等处都可以贴覆减振材料等。而要滤除由空气中传来的噪声,在汽车环境中,比较难以处理。一般只能对汽车的密封性做处理,也就是对汽车的橡胶边条做良好的处理,特别是在yabo亚博体育苹果下载过程中反复拆除,会使其密封性不好。
    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
    由于前声场的车门就如同音箱的箱体,所以要求门板的密封性非常好。汽车车门上有众多的维修孔,如果没有处理,就会使扬声器的背面所发出的相位相反的声音与前面的声音相干涉,特别使波长较长的低频衰减严重。如果门板处理不好,就会使良好的低频响应的顶级套装的声音大打折扣。在yabo亚博体育苹果下载前声场时,密封的处理方法是利用铅板或铝板等将维修孔封闭,并将所有的部分全部用胶密封处理良好。这样可使低频下潜延伸更低,产生良好的控制力,声音清晰度加强。
    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.
