Abstract : The patent describes a transducer which includes an element assembly acoustically coupled to a boot by silicone grease, such as di-methyl polysiloxane oil and silicone oxide. A method of assembling the transducer may comprise coating an elongated element assembly with the silicone grease; inserting an elongated resilient boot into an evacuating tube which is open at one end and closed at an opposite end; drawing a vacuum inside the tube at a position intermediate its ends for expanding the boot tightly against the inner surface of the tube; inserting the coated element assembly into the expanded boot; wiping the silicone grease smooth on the element assembly as the assembly is inserted into the tube; releasing the vacuum inside the tube; and withdrawing the assembly and boot from the tube.
