摘要 |
Pluralities of electrode groups are formed on one face of a piezoelectric element, and a common electrode is formed on another face. The common electrode is connected to a booster circuit for boosting a voltage signal obtained from an amplifier circuit. The pluralities of electrode groups are connected to selection circuits for switching a signal path of a signal output from here.
