The detection unit can detect parameter difference of the feature unit according to the distance variation of the connecting component relative to the base, so as to determine the distance between the working surface and a bottom of the base via the parameter difference.

Abstract: A top port MEMS microphone package includes a substrate having a back volume expanding aperture therein. A MEMS microphone electronic component is mounted to the substrate directly above the back volume expanding aperture such that an aperture of the MEMS microphone electronic component is in fluid communication with the back volume expanding aperture. A lid having a lid cavity is mounted to the substrate. The back volume expanding aperture couples the aperture of the MEMS microphone electronic component to the lid cavity. By coupling the lid cavity to the aperture with the back volume expanding aperture, the resulting back volume is essentially the size of the entire top port MEMS microphone package. In this manner, the noise to signal ratio is minimized thus maximizing the sensitivity of the top port MEMS microphone package as well as the range of applications.
