Abstract
An apparatus is provided including at least one electronic component. The apparatus also includes an enclosure enclosing the at least one electronic component. The enclosure includes at least one wall defined by a membrane. The apparatus further includes a piezoelectric actuator that is fixed at a first end and rigidly attached to the membrane at a second end. Application of alternating current to the piezoelectric actuator generates a pulsating mechanical deformation of the membrane.
Claims19
An apparatus, comprising:
- at least one electronic component;
- an enclosure enclosing the at least one electronic component, the enclosure including at least one wall defined by a membrane;
- an electromechanical transducer, wherein the electromechanical transducer comprises:
- a first piezoelectric actuator, a first end of which is fixed and a second end of which is rigidly attached to a first end of the membrane;
- and
- a second piezoelectric actuator, a first end of which is fixed and a second end of which is rigidly attached to a second end of the membrane, wherein application of alternating current to the first and second piezoelectric actuators generates a pulsating mechanical deformation of the membrane;
- and
- one or more openings in the enclosure for facilitating volume displacement of air from within the enclosure, wherein the volume displacement of air is provided by the pulsating mechanical deformation of the membrane.
A piezoelectric actuated assembly, comprising:
- a first piezoelectric actuator a first end of which is fixed;
- a second piezoelectric actuator a first end of which is fixed;
- and
- a compliant sheet having a first end that is rigidly attached to a second end of the first piezoelectric actuator, and a second end that is rigidly attached to a second end of the second piezoelectric actuator;
- wherein application of alternating current to the first and second piezoelectric actuators generates a pulsating mechanical deformation of the compliant sheet.
An apparatus, comprising:
- at least one electronic component;
- an enclosure enclosing the at least one electronic component, the enclosure including at least one wall defined by a membrane;
- and
- an electromechanical transducer, wherein the electromechanical transducer comprises:
- a first piezoelectric actuator, a first end of which is fixed and a second end of which is rigidly attached to a first end of the membrane;
- and
- a second piezoelectric actuator, a first end of which is fixed and a second end of which is rigidly attached to a second end of the membrane, wherein application of alternating current to the first and second piezoelectric actuators generates a pulsating mechanical deformation of the membrane.
