摘要
汽车音响是处在一个非常复杂的环境之中,它随时受到汽车发动机点火装置及各种用电电器的电磁干扰,尤其是车上所有电器都用一个蓄电池,更会通过电源线及其它线路对音响产生干扰。汽车音响的防干扰技术就分别对电源线的干扰采用扼流圈串在电源与音响之间进行滤波,对空间辐射干扰采用金属外壳密封屏蔽,在音响中专门安装抗干扰的集成电路,用以降低外界的噪声干扰。
本文论述了汽车音响的发展历史、组成、常见的故障及维护、主要的影响因素,同时论述了汽车音响的防干扰措施以及对音响的日常保养。
关键词:电力系统;杂音;防干扰;故障。
ABSTRACT
Car audio is in a plex environment, it stands by the ignition device and a variety of electric appliances of ic interference, especially in the car all the electrical appliances are using a battery, it will through the power lines and other lines of sound interference. Car audio interference on the anti-power line interference were used on the choke in the power and audio series between the filter, interference on the space radiation shielding metal case sealed, installed specifically interference in audio integrated circuits for reduce outside noise.
This article discusses the history of car audio, composition, common faults and maintenance, the main factors, also discussed the anti-interference measures for car audio and the sound of the daily maintenance.
Key words:electric power system Noise anti-interference failure;
