Filed: 1981-03-17
Abstract: PURPOSE: To make the axial characteristic of a horn even and improve the tone quality by providing a folded part on the side wall and applying a frequency characteristic to the directional angle.  
     CONSTITUTION: A horn 3 constitutes a sectorial horn ad the width W 1  of a connection part between a throat part 4 and a sectional part 5 is selected so as to be shorter than the wavelength of the upper limit frequency. A sidewall 6 is bent like a polygonal line and opening angles θ are increased stepwise: the opening angle is θ1 at the part that the diameter of a cylinder is W1 and θ2 at the horn part whose bottom diameter is W2. The sectional area of the born 3 is changed by curving the surface of the upper and lower walls in the same manner as an ordinal sectional horn. When frequency exceeds the one that the legnth l of the side wall is almost equal to the wavelength, even diffusion can be obtained at the angle θ2. Moreover, necessary audible range can be secured by selecting angle θ1 as the smallest angle to be required and the angle θ2 as the sufficient value to be required.
