Vibroacoustic structure system

A vibroacoustic structure system (1) comprising a body (2) in an air vehicle, which is subjected to vibration;

• a plurality of unit cells (3) located on the body (2);
• a plate (4) located on the body (2), which comprises said plurality of unit cells (3);
• at least one vibration source (V) which creates vibration on the body (2);
• said unit cells (3) configured to substantially absorb the vibration created on the body (2);
• said unit cells (3) located on the plate (4) with an almost completely fixed form, characterized by a plurality of intermediate cells (5) located on the plate (4) and between the unit cells (3), containing shape memory alloy material;
• an actuator (6) located on the body (2), which energizes the intermediate cells (5), thereby enabling the intermediate cells (5) to change shape and/or form;
• the plate (4) having a first position (I) in which at least two unit cells (3) move away from each other due to the intermediate cells (5) changing shape and/or form when triggered by the actuator (6), a second position (II) in which at least two unit cells (3) approach each other due to the intermediate cells (5) changing shape and/or form when triggered by the actuator (6), thereby allowing that vibrations at multiple types of frequencies reaching thereon simultaneously are absorbed.
