    1、济南汽车音响改装http://www.sdcarmusic.com/介绍安装扬声器的支架、底板(车门)刚性不够,当汽车上的扬声器发声时,由于喇叭的声波不但会向前输送,而且同时也向后传输,当向后传输的声波冲击底板时底板就会随扬声器产生共振或抖颤,导致扬声器的声压受到损失,并引起扬声器的谐波失真,从而导致音质恶化。
    Jinan car audio conversion describes how to install the speaker bracket plate (doors) rigid enough, when the car sound speaker, not only due to the sonic horn fed forward, but also backward transmission, when the transmission of sound

    waves back impact plate when the floor will resonate with the speakers or tremors, leading to a loss of sound pressure of the speaker, and the speaker of the harmonic distortion caused by, resulting in deterioration of sound quality.
        
    2、济南汽车音响改装http://www.sdcarmusic.com/谈到安装扬声器的箱体(车门)密封性不够,中低音喇叭向前与向后两个方向的声波相位相差了180度。由于低频声波的波长较长,其绕射能力强,使得低频声波的方向性很弱,由于车门喇叭安装面板上面充满了孔洞,向后辐射的声波就会绕到前面与前面的声波相互抵消,则会使向前传输的声波辐射能量被大大削弱(即声短路)。
    Jinan modified car stereo speakers talked about the installation of the box (door) tightness is not enough, the subwoofer forward and backward wave phase difference between the two directions of 180 degrees. Since the low-frequency sound of longer wavelength, its diffraction ability, so that low-frequency sound directivity is weak, due to the speaker mounting panel above the door full of holes, acoustic radiation will be back around to the front and the front sound waves cancel each other out, sonic will make the onward transmission of radiant energy is greatly reduced (ie sound short).
