'''调谐器'''是某些车载主机所具有的FM/AM调谐器或TV调谐器，具有这些调谐器的车载主机也就具有了FM/AM收音或[[电视接收功能]]。

一般车载主机的调谐器都是指收音机FM/AM调谐器。FM和AM都是信号调制方式，FM是指调频，AM是指调幅。调制技术的应用非常广泛，但是由于最早也是最常见的应用是收音机，因此也常常用FM或者AM表示广播收音机功能，又以FM为主，在广播中经常听到的“[[调频立体声]]”或者“调频92.7兆赫”等就是指FM。<ref>[https://wenku.so.com/d/b633377146d69260a85c3574aa6c27eb 调谐器介绍(原理)],360文库 , 2018年1月3日</ref>
