摘要:
There are provided a fixed focus transducer array and an ultrasonic wave transceiving apparatus using the same. The fixed focus transducer array includes: a plurality of transducers, transducing electrical signals into ultrasonic signals to thereby focus the ultrasonic signals on a single focal point and transducing reflected ultrasonic signals from the single focal point into electrical signals to thereby output the electrical signals, wherein the plurality of transducers are disposed to be symmetrical to each other based on one transducer and simultaneously focus the ultrasonic signals on the single focal point at speeds according to the respective natural frequencies thereof. Therefore, a circuit area is reduced, whereby miniaturization may be implemented and a processing speed may be increased.
