    • A resonant knock sensor includes a housing, a pedestal and a vibration diaphragm. The housing is provided with a support surface therein. The pedestal is fixed in the housing and has a base with a bottom surface attached to the support surface, a support portion protruding from a top surface of the base, and a vibration piece connected to an end of the support portion. The vibration diaphragm is mounted on the vibration piece. As a result, pedestals with different geometric sizes in their support portions or vibration pieces can be selectively assembled with single sized housings and vibration diaphragms to fabricate sensors with different frequency sensibilities at a low manufacturing cost.
    • 谐振爆震传感器包括壳体,基座和振动膜片。 壳体在其中设置有支撑表面。 基座固定在壳体中,并且具有底部,底部表面附接到支撑表面,从基座的顶表面突出的支撑部分和连接到支撑部分的端部的振动片。 振动膜片安装在振动片上。 结果,在其支撑部分或振动片上具有不同几何尺寸的基座可以选择性地组装有单个尺寸的壳体和振动隔膜,以低制造成本制造具有不同频率灵敏度的传感器。
