CYLINDRICAL PIEZOELECTRIC RECEIVER

摘要

FIELD: measurement equipment. ^ SUBSTANCE: invention is related to the field of acoustic measurement equipment. Metal disk is arranged as a whole with axis passing trough its centre, and is adhered to ends of piezoelectric cylinders. ^ EFFECT: improved vibration stability achieved by the fact that device is made of two identical piezoelectric cylinders, metal disk and axis. ^ 5 dwg
