  • Piezoelectric audio chime
    Patent number: 5793282
    Abstract: An electronic chime is created by a piezoelectric transducer with an exponentially decaying audio signal. The electronic chime has a power supply, an oscillator, a drive circuit, and a piezoelectric transducer. The drive circuit contains reactive components that function with the piezoelectric transducer to modulate the amplitude of the decaying audio signal. The amplitude modulated audio signal better simulates a mechanical chime.
