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.

[ What is claimed is:] [1.] An environmentally sealed acoustic transducer having a transducer case with an outer peripheral surface, comprising;an end surface of the transducer case bounded by the outer peripheral surface, the end surface comprising a region of transmission of acoustic energy from a vibration producing transducer element in the transducer case to a structure;an outer housing having a chamber defined by a surface for receiving the transducer case outer peripheral surface, and having a first end and a second end positionable adjacent a structure, a seal around the periphery of the outer surface of the transducer case spaced from the end surface to seal the transducer case relative to the surface defining the chamber and enclose a space between the end surface and the second end of the chamber; anda passageway opening into the chamber between the seal and the second end of the chamber, and extending to a location that is to the exterior of the outer housing when the transducer case is positioned in the chamber to permit flowable material engaged by the end surface of the transducer case to escape through such passageway as the transducer casing is moved into the chamber from the first end toward the second end.
