Claim:
1. A micro-perforated vibrating membrane piezoelectric atomizer comprising: a rigid piezoelectric transducer body having a first end defining an opening and a second end, an inside of the piezoelectric transducer body comprising a cavity for containing a liquid to be atomized, and said body further comprising a symmetry axis, a micro-perforated vibrating membrane covering said opening, wherein the micro-perforated vibrating membrane has an internal side toward the cavity and an external side away from the cavity and has micro-holes having a shape with equivalent diameter ranging from 1 μm to 100 μm, wherein the liquid does not seep from the membrane when the atomizer is not activated, and wherein the liquid does pass through the membrane when the atomizer is activated such that there is a vibratory speed causing displacement of the membrane, and wherein the rigid piezoelectric transducer body comprises a constant cylindrical section from the opening to a singular annual flange, with an annular piezoelectric member located just downstream of the flange element, wherein the piezoelectric member is adapted and arranged so as to vibrate the piezoelectric transducer body, wherein the piezoelectric member is positioned closer to the second end than the first end in order to vibrate the piezoelectric transducer body in a direction parallel to the body's symmetry axis, wherein said vibrating membrane is directly connected to the first end, wherein said vibrating membrane is mechanically coupled to the first end by gluing, brazing, crimping, welding, or overmoulding, and wherein said vibrating membrane is acoustically coupled to the first end.
