汽车音响噪音解决方案！！！！！！！！

楼主^#

更多发布于：2006-07-28 22:50

在使用汽车音响或更换音响之后，音响会产生多种噪音，噪音能影响音质，降低音响的指标，甚至使整个音响系统无法收听，针对噪音问题，介绍噪音的来源和基本排除方法。 一、
噪音的来源 噪音可以从以下途径侵入汽车音响系统。 1、侵入电源线（通过主机和功放电源线进入系统）。 2、通过地线的电流（通过天线的地线和功放的地线）。 3、受其他电线线束的感应（通过天线接收和原车线束感应）。 4、用电器的干扰（电喇叭、电动机等）。 1、2、3项是有相关性的。 <p class="MsoNormal" align="left" style="BACKGROUND: white; MARGIN: 0cm 0cm 0pt; WORD-BREAK: break-all; TEXT-INDENT: 18pt; TEXT-ALIGN: left; mso-pagination: widow-orphan; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;"> 二、应付噪音的对策<span style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-bidi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">一般对付噪音使用的零件，有汽车电容器或同轴汽车电容器（应付高频噪音特别有效），厄流圈（电感），<span lang="EN-US" style="FONT-SIZE: 12pt; FONT-FAMILY: "Times New Roman"; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">LC<span style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-bidi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">滤波器，接地线，二极管等。

噪音问题是汽车音响故障中，原因最多和较难排除的，因为汽车的结构和线路较复杂，易产生噪音的地方较多，所以应掌握一些汽车电路和汽车音响方面的知识，排除故障才能得心应手。排除方法：首先根据噪音情况，通过原理分析和判断找出故障所在部位，再采取不同排除方法。简单排除办法，先听音响的收音、磁带和CD部分是否都有噪音，如果都有应检查电源线、地线、信号线，走线的部位是否合理，信号线有无松动外皮是否破裂搭铁，功率放大器应与车身绝缘。针对不同的噪音来源，采取不同的措施进行处理，如果噪音不能排除，是把产生噪音信号源处理掉，然后再采取防噪音措施，这样一来才能将噪音彻底解决。
