    摘要： A sonar transducer assembly comprising: at least one transducer element; a flexible printed circuit board (PCB) comprising at least one set of electrical connections for the at least one transducer element, wherein the PCB comprises flex tabs configured to flex; and a support structure comprising at least one aperture for the at least one transducer element, wherein the support structure is configured to: support the PCB; allow flexion of a pair of opposing flex tabs into the aperture; and retain the at least one transducer element in the at least one aperture, wherein the transducer element is installed through the pair of opposing flex tabs on the PCB and into the aperture causing the flex tabs to flex, wherein the flexion of the flex tabs causes an elastic force to be applied against opposing ends of the at least one transducer element.

    摘要： According to one embodiment, an ultrasonic generator (10) includes ultrasonic transducers (22) and a drive unit (12). The ultrasonic transducers (22) each generate an ultrasonic wave. The drive unit (12) supplies a drive signal generating the ultrasonic wave to each of the ultrasonic transducers (22), and changes phase of the drive signal supplied to a second ultrasonic transducer (22-2) relative to the drive signal supplied to a first ultrasonic transducer (22-1). The second ultrasonic transducer (22-2) is located in a position in which a traveling direction of a combined wave front of a first combined wave is aligned with a frontal direction, the first combined wave being formed by combining the ultrasonic waves generated by the first ultrasonic transducer (22-1) and the second ultrasonic transducer (22-2), wherein the position is more frontward in the frontal direction of the first ultrasonic transducer (22-1) than the first ultrasonic transducer (22-1).
