Equipment for conveying acoustic vibration comprises acoustic source within confining tank, output nozzle and one or more pipes applied to structure with or without contact

摘要

Acoustic source (2) is connected rigidly within metal confinement tank (1) which has output nozzle (3). Output nozzle enables one or two pipes (4) to be connected and pipes may be applied to structure (5) with or without contact. Application without contact requires pipe ends to be flush with structure and application with contact requires pointing pipe end to structure.
