[0024] like Figure 1-6 As shown, a set angle directivity sound output device based on a planar waveguide horn combination includes a planar waveguide horn assembly, a mounting panel a1, and more than two tweeters a2. In this embodiment, the number of tweeters a2 is set to six, such as Figure 3 and 6As shown, the mounting panel a1 is arranged in an arc shape on the speaker box 01, and more than two mounting holes a3 matching the tweeter a2 are symmetrically arranged in the same direction of the mounting panel a1. The tweeter a2 is mounted on the mounting hole a3 of the mounting panel a1, and the mounting hole a3, the tweeter a2 and the planar waveguide horn are coaxially arranged to ensure that the sound of the tweeter a2 can pass through the planar waveguide horn, thereby making the sound effect and the directivity of the treble better. In addition, in this embodiment, the interval angles of adjacent mounting holes a3 on the mounting panel a1 can be set to be the same or different according to actual requirements. In this way, since the mounting hole a3, the tweeter a2 and the planar waveguide horn are coaxially arranged, by setting the interval angles of adjacent mounting holes a3 to be the same or different, the interval angles of adjacent planar waveguide horns fixed on the mounting panel a1 can be made. The degrees are the same or different, thereby enhancing the directivity of the sound of the tweeter a2; a mounting surface a11 is provided on the mounting panel a1, and the mounting surface a11 is located on the four sides of the mounting hole a3. The mounting surface a11 is provided with connecting holes (not marked in the figure) for fixing and installing the planar waveguide horn assembly. In this embodiment, the planar waveguide horn assembly is fixed to the mounting surface a11 by connecting the screws with the connecting holes. The planar waveguide horn assembly includes more than two planar waveguide horns, and the planar waveguide horns are arranged on the outside of the tweeter a2. The more than two planar waveguide horns are fixed on the mounting surface a11 as a unit body and correspond to the position of the tweeter a2. In this way, the problem of poor stability of the contact between the planar waveguide horn and the tweeter a2 is solved, thereby achieving the enhancement of the sound effect of the tweeter a2, thereby avoiding affecting the sound directivity of the tweeter a2.

In the present embodiment, the cross-sectional shape of the second sound guide opening a232 is set to be rectangular, and the width of the second sound guide opening a232 matches the width of the sound guide cover a23. From the first sound guide opening a231 to In the direction of the second sound guide opening a232, the sound guide space gradually becomes larger, and the other side of the sound guide cover a23 is also provided with a first side surface a233 and a second side surface a234, and the upper and lower sides of the plane where the second sound guide opening a232 is located are respectively obliquely connected to the first side surface a233 and the second side surface a234, and the upper and lower sides of the second sound guide opening a232 are symmetrically provided with more than two sound guide holes a235, and the sound guide holes a235 are respectively arranged on the first side surface a233 and the second side surface a234, so that after the sound guide cover a23 is fixed to the tweeter a2 by screws, the first sound guide opening a231 can be abutted against the plane waveguide sound tube a21, thereby fixing the plane waveguide sound tube a21 between the sound guide cover a23 and the tweeter a2, and at the same time, the sound output of the tweeter a2 can be transmitted to the first sound guide opening a231 and the sound guide hole a235 through the plane waveguide sound tube a21.

[0026] like Figure 4 and 5 As shown, a sound outlet hole a221 corresponding to the second sound guide opening a232 is provided in the middle portion of the sound outlet cover a22, and a sound guide cavity a222 corresponding to the sound guide hole a235 is provided on the upper and lower sides of the sound outlet hole a221, and the sound guide cavity a222 is connected with the sound outlet hole a221, so that the high sound passing through the second sound guide opening a232 in the sound guide cover a23 can be directly conducted out through the sound outlet hole a221, and at the same time, the high sound passing through the sound guide hole a235 in the sound guide cover a23 can enter the sound guide cavity a222, and then be conducted out through the sound outlet hole a221.
