Abstract
A capacitive transducer system has a capacitive transducer, and a controller. The capacitive transducer includes a first fixed electrode, a second fixed electrode, and a vibration electrode disposed between the first fixed electrode and the second fixed electrode so as to face the first and second fixed electrodes through gaps. A first capacitor is formed by the first fixed electrode and the vibration electrode. A second capacitor is formed by the second fixed electrode and the vibration electrode. The capacitive transducer is configured to convert transformation of the vibration electrode into changes in capacitance in the first capacitor and the second capacitor. The controller is configured to process voltages supplied to the first capacitor and the second capacitor and/or signals based on the changes in capacitance of the first capacitor and the second capacitor.
