Abstract
An ultrasonic transreceiver is disclosed which is capable of substantially preventing the formation of a gas boundary layer between a piezoelectric transducer and a housing and the breakage of the transducer due to thermal stress and ensuring satisfied electrical connection in the transreceiver. The ultrasonic transreceiver includes a spring for downwardly forcing the piezoelectric transducer arranged in the housing against a bottom surface of the housing. The transreceiver may include a viscous or elastic member arranged between the housing and the piezoelectric transducer to prevent a gas boundary layer from being formed therebetween. Also, the transreceiver may include a coiled spring laterally arranged between the housing and the piezoelectric transducer to forcedly press them apart from each other and electrically connect them to each other.
