A dome made of neoprene rubber or the like; 3 is the base of the dome; 4 and 5 are the transducer rows 1;
A main shaft and a sub-shaft 6 for supporting and driving the transducer element are made of the same electrostrictive or magnetostrictive material as the transducer element, and are located at positions that do not interfere with the directivity characteristics of the transducer array 1.
This is a monitoring transducer provided at approximately the same distance from each of the elements 1a to 1n, and the figure shows an example in which it is installed directly below a transducer row 1.

検監視できる。 Since the present invention is constructed as described above, if power is sent from the monitor circuit 7 to the monitor transducer 6 and a sound wave is emitted, each transducer element 1a to 1n will be approximately equal to the monitor transducer 6. Because of the distance, the sound wave path shown in 11.
Since the emitted sound waves arrive at each element almost simultaneously, electric power is induced by the sound waves, and the wave receiving characteristics of the transducer array 1 can be inspected and monitored by the sonar wave transmitting/receiving circuit.
