Design and Fabrication of a Wideband Cymbal Transducer for Underwater Sensor Networks

Cymbal transducers are characterized by a high mechanical quality factor and low power efficiency. The research conducted so far on cymbal transducers has focused on improving the power efficiency and structural stability, but modern underwater sensor network systems need transducers to have a wide...
