Abstract: A MEMS device includes a first plate coupled to a second plate and a fixed third plate formed on a first substrate. The first and second plates are displaced in the presence of an acoustic pressure differential across the surfaces of the first plate. The MEMS device also includes a first electrode formed on the third plate and a second electrode formed on the second substrate. The first, second plate, and third plates are contained in an enclosure formed by a first and second substrates. The device includes an acoustic port to expose the first plate to the environment. The MEMS device also includes a first gap formed between the second and third plates and a second gap formed between the second plate and the second electrode. The displacement of the second plate causes the first gap to change inversely to the second gap.

Abstract: A MEMS device is disclosed. The MEMS device comprises a first plate with a first surface and a second surface; and an anchor attached to a first substrate. The MEMS device further includes a second plate with a third surface and a fourth surface attached to the first plate. A linkage connects the anchor to the first plate, wherein the first plate and second plate are displaced in the presence of an acoustic pressure differential between the first and second surfaces of the first plate. The first plate, second plate, linkage, and anchor are all contained in an enclosure formed by the first substrate and a second substrate, wherein one of the first and second substrates contains a through opening to expose the first surface of the first plate to the environment.
