Abstract:
1. A device for generating acoustic energy, comprising: a substrate; at least one deformable cavity disposed in the substrate and being delimited by at least one mobile or deformable wall, the at least one deformable cavity extending in a lateral direction in the substrate defined by a first plane parallel to an upper surface of the substrate; at least one opening disposed in an upper portion of the at least one deformable cavity, configured to transmit at least one pulse produced in the at least one deformable cavity to an ambient atmosphere, the at least one pulse being a pressure pulse, a depression pulse, a partial vacuum pulse, or a combination thereof; and at least one actuator configured to generate a force in the first plane that displaces or deforms, or displaces and deforms, the at least one mobile or deformable wall.
