  • Low frequency acoustic transducer for a probe for non-destructive testing
    Patent number: 8264127
    Abstract: The present invention provides a low frequency acoustic transducer for non-destructive testing of a test structure. The transducer is arranged for conversion between electrical energy and acoustic energy associated with an acoustic wave propagating through a portion of the test structure. The transducer comprises a bending actuator for generating the acoustic wave by generating a vibration from an electrical signal or for generating an electrical signal from a vibration generated by the received acoustic wave. The bending actuator has a vibration surface and a contact area surrounded by a portion of the vibration surface. The transducer further comprises a mode setting member that has a rigid portion which is in direct mechanical contact with the bending actuator at the contact area such that, within the contact area, an amplitude of the vibration is substantially suppressed. The location and shape of the contact area determine a bending mode associated with a resonance frequency of the bending actuator.
