The air storage Chambers are communicated with two ends of the cylinder body through fabricationholes.
所述储气室与缸体两端通过工艺孔相通。

The resulting laser-machined holes have a much higher aspect ratio (diameter to depth ratio) than holes achieved with standard fabrication techniques.
激光加工产生的孔比标准制造技术有更高的直径深比。

The backside holes of prior art microphones typically require that a secondary machining operation be performed on the rear surface of the silicon wafer during fabrication.
