  • Underwater wide-band electroacoustic transducer and packaging method
    Patent number: 6750595
    Abstract: An underwater wide-band electroacoustic transducer and a method of packaging the transducer. The underwater wide-band electroacoustic transducer comprises of several groups of piezoelectric ceramic units and acoustic window material. To produce the underwater wide-band electroacoustic transducer, groups of piezoelectric ceramic units each having a different dimension are assembled such that each ceramic unit separates from each other by different distances. The frequency response of each ceramic unit groups are added together to provide a wide-band frequency response. The acoustic window material is injected to joins the ceramic unit groups together into a package.
    Type: Grant

    Date of Patent: June 15, 2004
    Assignee: Chung-Shan Institute of Science and Technology
    Inventors: Sheng-Dong Dunn, Chi-Zen Yeh, Jeng-Yow Jih
