摘要
收音作为车载音响的基本功能,受到音响本身芯片选型、天线系统平台匹配和使用环境的影响。其干扰源可分为车内电气系统噪声和车外电台干扰。本文简单介绍天线系统的组成、与音响系统的匹配工作原理,以及收音系统正向开发流程,为车载收音机的收音效果设计提供保障。
Radio as a basic functions of car audio, is affected by the chip selection, antenna system platform matchingand working environment. The jamming mode can be divided into two types, which are the noise of electric system and the interference of external station. Discussion on composition of the antenna system and its matching principle with audio system is the focus of this paper. It also introduces the forward development process of the radio receiver system, and provides guarantee for the sound effect design of the car radio.
