An acoustic transducer for a borehole logging tool.

摘要

A bender acoustic transducer has a flat, piezoelectric element (26) affixed to a flat, elongated inert element (27). The ends of the inert element (27) are hinged on a supporting rectangular frame (28) which has a rectangular opening. Opposite surfaces of the transducer are exposed so that when a voltage is applied, a dipole acoustic wave is generated by the transducer.
