汽车音响专用晶振FA-238编码Q22FA2380004100
音响中的晶振其音响类型不同所用到的晶振也有所不同。比较常用的有3.2x2.5的贴片晶振，一般的插卡音响专用晶振有49S晶振,圆柱插件晶体。常用频率有：32.768KHz、3.57954MHz、12MHz、16MHz、24MHz等。汽车音响用的晶振是12MHz和24MHz，车载音响还会用到时钟晶振32.768KHz。而音箱和低音炮里面用到的晶振一般比较常用的是32.768KHz,晶振和音响主板配套晶振有源贴片5.0x7.0mm的温补晶振。
而音响的音质关键却是晶振的精度。顾名思义，晶振精度越高音响音质越好。就像所有时钟产品里面所用的32.768KHz晶振一样，其精度高低直接影响时间的准确。
