method and transducer for the coverage of broadband and low frequency sound waves in unlimited depth

摘要

the transducer includes at least one electro-acoustic motor (1) setting all the walls of the device vibrating for transmission of waves. A hollow box (5) encloses the motor, defining the vibrating wall (3) surrounding a cavity (7). The transducer also includes at least one opening (6) allowing communication between the cavity and the ambient medium (4). One of more flexible containers (8) are provided, holding a compressible fluid (9) which occupies the space between the electro-acoustic motor (1) and the vibrating walls (3).
