圧電振動子の駆動装置
Document Type and Number:
Japanese Patent JP7369540
Kind Code:
B2
Abstract:
To provide a new technology suitable for drive of a piezoelectric vibrator.SOLUTION: A driving device 100 includes a network 150 for generating a resonant condition containing a piezoelectric vibrator PZT as an element at an application time of a driving signal to the piezoelectric vibrator PZT which is a driving object, and an oscillator 120 for generating a driving signal near a resonance frequency of the piezoelectric vibrator PZT by utilizing an electrical characteristic appearing in the network 150 in the resonant condition.SELECTED DRAWING: Figure 1
