超音波送受波器。 A metal funnel-shaped resonator is coupled to the center of the bimorph oscillator to form a composite vibrating body, and while the vicinity of the node diameter of this composite vibrating body is elastically supported by the base, ultrasonic waves can be transmitted and received. In an ultrasonic transducer that houses a composite vibrator in a case with an opening for ultrasonic waves, the space formed between the funnel-shaped resonator and the bimorph vibrator is closed with an elastic body. Transducer/receiver.
