Patent ID: 8611189

Claim:
An acoustic coupler adapted to be disposed between an acoustic transducer and a physical mass to acoustically couple the acoustic transducer with the physical mass, the acoustic coupler comprising: a liquid chamber, the liquid chamber including— a liquid inlet configured to be coupled in fluid communication with a supply volume for holding a circulating liquid; a liquid outlet configured to be coupled in fluid communication with a discharge volume for the circulating liquid; a first surface configured to conform to the acoustic transducer; and a second surface configured to conform to the physical mass; and a pouch coupled with the liquid chamber, the pouch being configured to removably secure the acoustic coupler to the acoustic transducer, the pouch comprising an open-ended volume configured to receive the acoustic transducer such that when the acoustic transducer is inserted into the open ended volume, the first surface of the acoustic coupler conforms to the acoustic transducer, wherein the circulating liquid in the liquid chamber and the open-ended volume are separated by the first surface, the pouch being formed from a flexible elastomeric material configured to achieve an interference fit with the transducer.
