3225四脚Q22FA2380017000爱普生石英晶振材料水晶的压电效应
石英压电效应如果在石英晶体两个表面施加电场,则晶片在电轴和机械轴方向将延伸或压缩,这种现象称为逆压电效应.爱普生晶振基于这种特性,当石英晶振置于交变电场中,晶体的体积会发生周期性的压缩或拉伸,形成了晶体的机械振动.当交变电场的频率等于晶片的固有机械谐振频率时,晶片的机械振动幅度最大,产生共振现象.

石英晶振的主要功能材料为水晶,即一种化学成分为二氧化硅（SiO2）的六角锥形结晶体.石英之所以成为谐振器的原材料,是由于它具有正（机械能→电能）、逆（电能→机械能）压电效应.日本进口晶体如果沿石英晶片的电轴或机械轴施加压力使晶片产生形变,那么垂直于这些轴的两个表面则会产生电荷,这种现象称为正压电效应.
