1. Wave guide system that is used for radiative acoustic wave, described Wave guide system comprises:

  • The low-loss waveguide of emission sound wave, described waveguide comprises;

    Be suitable for being coupled to the first terminal of acoustic wave source;

    Be suitable for second terminal of described acoustic irradiation to external environment condition;

    Center line along the length of described waveguide trend;

    In perpendicular to the plane of described center line around the wall of area of section;

    It is characterized in that;

    described wall is taper, so that the area of section that is positioned at described second end is less than the area of section that is positioned at described first end.
