Vibrating device comprising embedded mechanical reflectors for defining an active plate mode propagation area and mobile apparatus comprising the device
First Claim
1. A vibrating device comprising:
- a first support configured to be deformed having a surface defined in a plane in directions X and Y, said first support comprising at least one defect with respect to the propagation of the plate modes, said defect being of geometrical nature or corresponding to a structural heterogeneity;
at least one actuator configured to generate plate modes being propagated in said first support;
a second support;
at least one embedded mechanical reflector in contact with said first support, the at least one embedded mechanical reflector is secured to said first support such that the first support is immobilized in at least one direction Z at right angles to said directions X and Y, said mechanical reflector being secured to said second support, whereinsaid embedded mechanical reflector being configured to isolate an active zone belonging to said surface defined in a plane in directions X and Y in which the plate modes are propagated, said active zone excluding said defect,said actuator being situated in said active zone,said embedded mechanical reflector is in contact on at least a first surface with the first support and on at least a second surface with the second support, the first and second surfaces of the embedded mechanical reflector are elongated, andthe first support including a bottom surface defined in a plane in directions X and Y and the second support including a top surface defined in a plane in directions X and Y that faces the bottom surface of the first support, the embedded mechanical reflector being secured to each of the bottom surface of the first support and the top surface of the second support.

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.
