    济南汽车音响改装介绍音响易失真的原因

    1、济南汽车音响改装http://www.sdcarmusic.com/介绍音响失真是由于安装扬声器的支架共振导致音质恶化。汽车上的扬声器发声时,由于安装扬声器的底板比较脆弱,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 introduce modified car stereo speakers sound distortion due to the installation of the bracket resonance leads to quality deterioration. When the car sound speakers, speaker of the floor due to the installation is relatively weak, the floor will resonate with the speakers or tremors, resulting in a loss speaker sound pressure and cause the speaker harmonic distortion, resulting in deterioration of sound quality.

    2、“声短路”影响低频辐射。低音单元的振膜在前后运动时,除了有向前方辐射的声波,也有向后方辐射的声波,两个方向的声辐射相位相差了180度。由于低频声波的波长很长,其绕射能力相当强。因此,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,后向辐射的声波就会绕到前面来与前方的辐射异相相消。
    "Sound short" affect low-frequency radiation. Woofer diaphragm at the time before and after exercise, in addition to sound waves radiated forward, but also to the rear acoustic radiation, acoustic radiation in two directions of the phase difference of 180 degrees. Because of the low-frequency acoustic wave is very long, its diffraction ability is quite strong. Therefore, the low-frequency sound directivity is weak, due to the speaker mounting panel above the door full of holes, after the acoustic radiation will come around to the front with different destructive and radiation ahead.

    3、济南汽车音响改装http://www.sdcarmusic.com/介绍音响失真还有个原因是喇叭安装空间不规则,引起声波变形。声场不规则是导致各种音质下降的主要原因。汽车音响扬声器发声时,声波不但向前输送,而且同时也向后传输,强反射及特殊反射使声音混淆不清,声音传导效果不清晰。
    Jinan modified car stereo audio distortion introduced there is a reason for speaker installation space is irregular, causing sonic distortion. Irregular leading to a variety of sound field sound decline. When the car stereo speaker sound, sound waves not only forward delivery, but also backward transmission, reflection and special reflections strong sound confusing, sound conduction effect is not clear.
