Spiral acoustic waveguide electroacoustical transducing system |
摘要 |
The invention features an acoustic waveguide and system for transmitting pressure wave energy produced by an electroacoustical transducer in a medium that propagates pressure wave energy. The acoustic waveguide and system includes a tube defining a spiral-shaped channel with a length of L. The tube has a first end and a second end with the first end closed and the second end open to the medium. The tube has a transducer opening for accommodating an electroacoustical transducer located between the first and second end of the tube. The system includes an electroacoustical transducer mounted to the acoustic waveguide.
