The invention relates to a reflection-type paraboloid sound guiding device which is characterized in that a forming method of the wall of a paraboloid sound guiding pipe comprises the following steps of: respectively outwards moving two symmetrical parts of a parabola from an original point; and then rotating a paraboloid formed by the parabola by taking the original point of the parabola as an axle centre before the parabola is outwards moved, wherein the top end of the paraboloid sound guiding pipe is a circular plane, the wall of the paraboloid sound guiding pipe is in a paraboloid shape, and the integral paraboloid sound guiding pipe is in a basin-shaped structure. The reflection-type paraboloid sound guiding device has a total acoustic pressure level in a 0-degree direction higher than that of the conventional high horn type loudspeaker by more than 3 dB when reproducing sounds under the condition of using a same sound head, is especially suitable for long-distance broadcasting with high directional property, has small size, light weight and convenient for carrying, transportation and installation, can be combined to line sound sources or surface sound sources of various types with different sizes if designed into a square in appearance and has intense directional property, higher output sound power and further broadcasting transmission distance due to the line sound sources or the surface sound sources combined by the loudspeaker.
