Original Abstract Submitted
An ultrasonic transceiver device and a control method thereof are disclosed. The ultrasonic transceiver device includes a plurality of coupled ultrasonic transceiver units. Each of the ultrasonic transceiver units includes a plurality of ultrasonic oscillators, a driving bias circuit coupled to the ultrasonic oscillators and used to receive an alternating current (AC) voltage, and a switching circuit coupled to the driving bias circuit. The switching circuit has a plurality of switching paths corresponding to a plurality of impedance values or a plurality of inductance values. The switching circuit is used to switch a system driving signal to pass through one of the switching paths according to a mode selection signal and transmitted to the driving bias circuit as the AC voltage.
