  • Piezoelectric assembly
    Patent number: 8446076
    Abstract: A piezoelectric assembly and portable electronic device having a piezoelectric assembly are described. The piezoelectric assembly comprises a first electrode for electrical communication to a current or voltage source, a second electrode for electrical communication to a reference source, a piezoelectric material in electrical communication with each one of the first and second electrodes and between the first and second electrodes, a signal electrical connector in electrical communication with the first electrode and configured to be connected to the current or voltage source, and a reference electrical connector in electrical communication with the second electrode and configured to be connected to the reference source so as to provide electrical communication between the second electrode and the reference source.
    Type: Grant
