Abstract:
A transducer device includes a coupling cavity, a first resonant element and a second resonant element. The first resonant element is coupled to the coupling cavity and configured to send or receive acoustic signals. The second resonant element is coupled to the coupling cavity and configured to modify a frequency response of the first resonant element via the coupling cavity.
