Patent 8072843 was granted and assigned to Image Acoustics Inc on December, 2011 by the United States Patent and Trademark Office.
An electro-mechanical transducer is disclosed, which provides a wideband response by activating successive multiple resonant frequencies in a way which provides additive output between the resonant frequencies with reduced cancellation below the first resonance and means for controlling the response by reducing the voltage drive. A multiply resonant wideband high output transducer is disclosed.
