Abstract
The invention discloses an angle-adjustable high frequency sound wave guide groove which comprises a circular cone core, a cone core, a casing a, a casing b and two blocking plates, wherein the cone core is formed by performing symmetrical inclined cutting along the large-end end face of a circular truncated cone body, and two symmetrical semi-ellipses are obtained after inclined cutting. The circular arc ends of the symmetrical semi-ellipses extend to the small end of the circular truncated cone body. The round-head end of the cone core is equal to the bottom surface of the circular cone core in diameter and connected with the bottom surface of the circular cone core. The two blocking plates are connected to the large-diameter end of the casing b and correspond to the surface positions of the two semi-ellipses respectively. The two blocking plates are in rotary connection with the casing b. The angle-adjustable high frequency sound wave guide groove can be used in a linear array or a conventional loudspeaker box.
