Abstract
An acoustic transceiver assembly including a housing, an oscillator, and a blocking element. The housing has at least one inner wall defining a cavity. The cavity has a first end and a second end defining an axis of said acoustic transceiver assembly. The oscillator is provided in said cavity. The oscillator is provided with a transducer element, and a backing mass positioned adjacent to the transducer element. A blocking element is positioned inside the cavity and adjacent to the oscillator. The blocking element is adapted to restrain a portion of said backing mass at a first pressure to thereby restrain the backing mass from lateral movement relative to the axis of the acoustic transceiver assembly. The blocking element is also adapted to release the backing mass at a second pressure.
