ACOUSTIC TRANSDUCER ASSEMBLY

摘要

An acoustic transducer assembly comprises a bipolar transducer (1 ) having an active surface with opposite ends that move towards and away from one another in response to an applied electrical fields. An acoustic decoupling material (2) is fixed to one end of the transducer surface, the acoustic decoupling material being such that it substantially prevents acoustic signals passing therethrough and substantially prevents coupling of the transducer's active surface.
