Abstract
A vibrating device comprises: a first support configured to be deformed having a surface defined in a plane in directions X and Y; at least one actuator configured to generate plate modes propagated in the first support; the first support comprising: at least one defect with respect to the propagation of the plate modes; the defect being of geometrical nature or corresponding to a structural heterogeneity; comprising: a second support; at least one embedded mechanical reflector secured to the first support and in contact with the first support, configured to immobilize the first support in at least one direction Z at right angles to the directions X and Y, the mechanical reflector being secured to the second support and; the embedded mechanical reflector being configured to isolate a so-called active zone belonging to the surface defined in a plane in directions X and Y in which the plate modes are propagated, the active zone excluding the defect; the actuator being situated in the active region.
