It should be noted that, the horn in the embodiment of the present invention is composed of a multi-layer composite structure, where each of the inner layer 1, the middle layer 2 and the outer layer 3 may include a plurality of sub-layers. Any two layers of the inner layer 1, the middle layer 2 and the outer layer 3 in the application are different in material, for example, the middle layer 2 and the inner layer 1 are different in material, or the middle layer 2 and the outer layer 3 are different in material, or the inner layer 1 and the outer layer 3 are different in material, or the three layers are different in material. Because the natural frequencies of the layer structures formed by different materials are different, the horn in the application is not easy to generate resonance, so that the self resonance can be effectively reduced in the use process, the reduction of the self resonance can reduce the sound and the dye of the music, and the reduction quality of the music is higher. In addition, the specific shape of the horn is not particularly limited in the present application, and the cross-sectional structure of the horn shown in fig. 1 is merely a schematic diagram of the horn, and the horn may have other specific shapes in addition to the shape shown in fig. 1.

Specifically, the diameter of each of the resonant plugs 22 in the present application may be set to 8mm, 10mm, 15mm, etc., the shape may be set to cuboid, hemispherical or pyramidal, etc., and the corresponding depth may be in the range of 3-5mm. Of course, the size and shape of each of the resonant plugs 22 should be determined according to the size and shape of the corresponding resonant holes 21, and the specific size and shape are not particularly limited in this application.
Further, the inner layer 1 is a first carbon fiber layer 11 and/or the outer layer 3 is a second carbon fiber layer 31.
In particular, the carbon fiber material has the advantages of high hardness and low coefficient, so the layer structure made of the carbon fiber material is not easy to deform. In addition, because the carbon fiber density is great, the structure of same thickness, the penetration resistance of carbon fiber is stronger, can make the sound output effect of horn better.
For the sake of aesthetic appearance of the horn, carbon fiber layers are preferably used for both the inner layer 1 and the outer layer 3. Further, the intermediate layer 2 includes a plurality of sub-intermediate layers, and the materials of every two adjacent sub-intermediate layers may be different. Specifically, each sub-interlayer may be an epoxy resin layer or a glass fiber layer, and of course, an interlayer made of other materials may be used, which is not particularly limited in this application.
Specifically, the thickness of the intermediate layer 2 is 1mm to 100mm. For example, the thickness of the intermediate layer 2 may be set to 5mm, but may be any other specific value, and may be specifically determined according to practical situations, and the present application is not limited thereto, and the object of the present application may be achieved.
