Abstract
An ultrasonic transducer having a container, a base an actuator and a membrane system. The membrane system can include a membrane, a mesa and a standoff. The mesa can be shaped to achieve one or more target frequencies and other target vibrational properties, such as amplitudes. The actuator may be a flexure having one or more electroactive materials, such as piezoelectric and/or electrostrictive materials. The flexure may be fixed at one end to a wall of the container be in communication with the membrane system at or around its other end. The actuator may be in contact with the membrane system through the mesa and/or the standoff. The standoff may include an adhesive filled with beads to achieve a specific thickness.
