智能健身镜，是一款人工智能+互联网技术深度结合的智能健身产品，它打破了传统健身所固有的模式，让足不出户的我们也能拥有健康的生活，那么智能健身镜使用到哪些晶振？

晶振在智能健身镜的作用：智能健身镜是以硬件+内容为载体，支持蓝牙或Wi-Fi连接，通过虚拟教练来为用户健身，提供实时指导与反馈，同时自带的AI摄像头和识别传感器，能够对用户的动作进行实时纠正。

对于智能健身镜这样智能化的电子产品来说，人机交互、语音识别等功能的实现必然离不开晶振的支持。这些晶振的作用主要负责实时时钟、程序指令时钟、蓝牙数据传输、开机、网关、有线网络数据、无线网络数据(WIFI)等。

智能健身镜专用晶振Q22FA23V0048200小体积3225mm晶振

智能健身镜系列产品中用到的晶振一般为2520晶振及3225晶振这两款主流封装。常用晶振频点有32.768KHz、12MHz、16MHz、24MHz、25MHz、26MHz、27.12MHz、32MHz、40MHz等。
一款好的智能健身镜，其电路板上使用的晶振元件必须具备高精度、高稳定性的特点，这样才能保证智能健身镜的各项功能稳定有序地运作。智能健身镜使用的晶振类型，可根据其电路设计的需求选择无源晶振或有源晶振方案。无源晶振需要外接电容与之匹配，而有源晶振输入额定电压即可输出所需时钟信号，具有更高稳定性及抗干扰等显著优势。
