Title:
ULTRASONIC TRANSDUCER ARRAY
Document Type and Number:
WIPO Patent Application WO/2016/038926
Kind Code:
A1
Abstract:
This ultrasonic transducer array (15) is formed by laminating an acoustic lens (30) to a laminate (LA) comprising a transducer part (24) including a transducer (20) and a first acoustic matching layer (21) and a second acoustic matching layer (22). In the laminate (LA), first grooves (23) of the transducer part (24) and second grooves (25) of the second acoustic matching layer (22) have the same groove width and are arranged such that the center of the groove width of each first groove (23) and the center of the groove width of the corresponding second groove (25) are located on the same line, thereby producing a lamination structure that is highly resistant to mechanical stress caused by bending. This configuration allows an ultrasonic transducer array with good ultrasonic wave propagation efficiency to be produced while avoiding problems such as separation of the transducer part (24) and the second acoustic matching layer (22) during bending so that manufacturing yield is not worsened.
