Title (EN) ACOUSTIC DEVICE AND METHOD OF FORMING THE SAME
(FR) DISPOSITIF ACOUSTIQUE ET PROCÉDÉ DE FORMATION DE CELUI-CI
Abstract:
(EN) Various embodiments may provide an acoustic device. The acoustic device may include a substrate, an electrically conductive first membrane, a first spacer holding the first membrane to form a first acoustic chamber between the substrate and the first membrane. The acoustic device may additionally include an electrically conductive second membrane, a second spacer holding the second membrane to form a second acoustic chamber between the first membrane and the second membrane, and a plurality of electrical pads in electrical connection with the first membrane and the second membrane.
(FR) Divers modes de réalisation de l'invention peuvent concerner un dispositif acoustique. Le dispositif acoustique peut contenir un substrat, une première membrane électroconductrice, un premier intercalaire maintenant la première membrane pour former une première chambre acoustique entre le substrat et la première membrane. Le dispositif acoustique peut aussi comprendre une deuxième membrane électroconductrice, un deuxième intercalaire maintenant la deuxième membrane pour former une deuxième chambre acoustique entre la première membrane et la deuxième membrane, et une pluralité de plots électriques en connexion électrique avec la première membrane et la deuxième membrane.
