1、濟南汽車音響改裝http://www.szanyuda.com/介紹音響失真是由于安裝揚聲器的支架共振導致音質(zhì)惡化。汽車上的揚聲器發(fā)聲時，由于安裝揚聲器的底板比較脆弱，底板就會隨揚聲器產(chǎn)生共振或抖顫，導致?lián)P聲器的聲壓受到損失，并引起揚聲器的諧波失真，從而導致音質(zhì)惡化。
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、“聲短路”影響低頻輻射。低音單元的振膜在前后運動時，除了有向前方輻射的聲波，也有向后方輻射的聲波，兩個方向的聲輻射相位相差了180度。由于低頻聲波的波長很長，其繞射能力相當強。因此，低頻聲波的方向性很弱，由于車門喇叭安裝面板上面充滿了孔洞，后向輻射的聲波就會繞到前面來與前方的輻射異相相消。
"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、濟南汽車音響改裝http://www.szanyuda.com/介紹音響失真還有個原因是喇叭安裝空間不規(guī)則，引起聲波變形。聲場不規(guī)則是導致各種音質(zhì)下降的主要原因。汽車音響揚聲器發(fā)聲時，聲波不但向前輸送，而且同時也向后傳輸，強反射及特殊反射使聲音混淆不清，聲音傳導效果不清晰。
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.
