Abstract
A micro-electromechanical systems (MEMS) package comprising: a MEMS package comprising a substate and a lid coupled to the substrate; a piezoelectric valve coupled to the substrate and comprising a number of movable members operable to be deformed in opposite directions upon application of a voltage to modify an acoustic resistance of an acoustic port; and a first stopper defined by the substrate and a second stopper defined by the lid, the first stopper and the second stopper being aligned with the number of movable members and operable to prevent an undesirable deflection of the number of movable members.
