    • A monolithic accelerometric transducer comprises a fixed part, two mobile mass parts and a resonator having ends fastened to said mobile parts, a flexible frame around the two mobile parts, and two connecting members connecting the frame to the second mobile part and to the fixed part. The frame provides a mechanical filter between the resonator and the fixed part which is not affected by the vibrations of the resonator. The quality factor Q of the resonator is not degraded and the measurement provided by the transducer is more accurate. In a differential output accelerometer, the position of the transducer is deduced from that of another, identical transducer by rotation of 180.degree. about an axis parallel to the resonator, the fixed parts of the transducers being fastened together.
    • 单片加速度传感器包括固定部分,两个移动质量部分和具有紧固到所述可移动部件的端部的谐振器,围绕两个可移动部件的柔性框架,以及将框架连接到第二移动部件和固定部件的两个连接构件 。 该框架在谐振器和固定部件之间提供机械滤波器,其不受谐振器振动的影响。 谐振器的质量因子Q不降低,并且由换能器提供的测量更准确。 在差分输出加速度计中,通过围绕平行于谐振器的轴旋转180°,推导出换能器的位置,换能器的位置被固定在一起。
