Abstract
A transducer, a method of manufacturing a transducer, and a transducing device are provided. The transducer includes a receiving unit and a transmitting unit. The receiving unit includes a first receiving electrode, a first piezoelectric film, and a second receiving electrode which are sequentially stacked, and the receiving unit is configured to convert a first acoustic wave signal into an electrical signal by using a piezoelectric effect of the first piezoelectric film. The transmitting unit is configured to receive a control signal, which is based on the electrical signal, to transmit a second acoustic wave signal.
