摘要： When a power switch is turned on, first and second analog switches are turned on while a third analog switch is turned off. Accordingly, at the time of starting, a forced excitation driving circuit supplies to a vibrator an oscillation output pulse which is substantially at the resonance frequency of the vibrator, thereby forcibly driving the vibrator in an excitation manner. Thereafter, when the vibrator substantially attains its stationary state and thereby the charged voltage of a capacitor reaches a threshold value of an inverter, the first and second analog switches are turned off while the third analog switch is turned on. Accordingly, the output of a self-excitation circuit is supplied to the electrode of the vibrator so as to vibrate the vibrator in a self-excitation manner.
摘要翻译：当电源开关打开时，第一个和第二个模拟开关打开，而第三个模拟开关关闭。因此，在启动时，强制励磁驱动电路向振动器供给基本上处于振动器的共振频率的振荡输出脉冲，从而以激励方式强制地驱动振动器。此后，当振动器基本上达到其静止状态，从而电容器的充电电压达到逆变器的阈值时，第一和第二模拟开关在第三模拟开关导通时关闭。因此，自激电路的输出被提供给振动器的电极，以便以自激的方式使振动器振动。
