<p>An assembly for utilization in a loudspeaker system is disclosed. The assembly comprises a substantially flat piezoelectric element (22) capable of being excited by applied electric potential, a diaphragm (21) that is driven by the excited piezoelectric element (22), said diaphragm (21) having a surface area that is at least 20 times the surface area of the piezoelectric element and at least one motion coupler (23, 24) which is attached to at least a portion of the outer perimeter of the piezoelectric element (22a) and on its underside to the diaphragm.</p> |
