Environmentally sealed acoustic transducer coupling

摘要

An environmentally sealed acoustic transducer that utilizes a semi-liquid, liquid or paste-like couplant material between a bottom surface of a transducer case and a structure that is to be acoustically vibrated. The transducer case fits into a chamber or well that provides a seal relative to the outer surfaces of the transducer case, and a weep or bleed passageway is provided and opens to the chamber or well. The bleed passageway permits excess couplant material to move out of the chamber through the passageway when the transducer case is inserted into the chamber or well. The bleed passageway has a seal so that the entire unit is environmentally sealed.
