[0018] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0020] In the utility model, the orientation such as "up, down" is generally for the direction shown in the drawing, or for the vertical, perpendicular or gravity direction, unless otherwise stated. Similarly, for the convenience of understanding and description, "left, right" is generally for the left and right shown in the drawing, and "inner, outer" refers to the inner and outer relative to the contour of each component. However, the above orientation words are not used to limit the utility model.

[0021] According to Figures 1-3 As shown in the figure, a bee calling device cover, including the hollow shell with the opening at one end 1, the other end of the shell 1 relative to the opening shaft center place is set up with the sound amplification hole 11, the one end of the shell 1 set up with the sound amplification hole 11 is provided with strong sound spare 2, strong sound spare 2 is set up as the cylinder of the right angle triangle section, and the movable connection of the end surface of the body shell is parallel to the other right angle edge and the axis of the sound amplification hole 11.

[0022] According to Figures 1-3As shown, the sound amplifying piece 2 can effectively change the direction of the sound waves emitted from the sound amplifying hole 11, making the sound waves more concentrated in the unobstructed direction, thereby playing a role of directional sound wave amplification. Because the sound amplifying piece 2 is movably connected with the shell 1, the position of the sound amplifying piece 2 can be changed to change the direction of the sound wave amplification.

[0023] According to Figures 1-3 As shown, the end surface of the shell 1 is provided with an annular clamping groove 12 coaxial with the hollow hole, and the sound amplifying piece 2 is provided with a clamping ring 21 matched with the annular clamping groove 12. The sound amplifying piece 2 made of plastic and the clamping piece made of plastic are integrally formed by secondary pouring. Figure 3 As shown, the upper part of the clamping ring 21 is rectangular, the lower part is circular, and the free end of the clamping ring 21 is spherical. Because the clamping ring 21 is made of plastic, it has a certain elasticity and can be matched with the clamping ring 21 more quickly. Because the surface of the plastic is rough, it can also prevent the sound amplifying piece 2 from moving after being adjusted to the appropriate position.

[0024] According to Figures 1-3 As shown, the sound amplifying hole 11 is arranged in a trumpet shape with gradually increasing inner diameter from inside to outside, and the inner wall of the sound amplifying piece 2 is plated with a bright surface layer. The trumpet-shaped sound amplifying hole 11 can better diffuse the sound in the shell 1 to the outside of the shell 1, and the diffusion range is larger. Then, in combination with the sound amplifying piece 2, the sound waves are concentrated to one side. The inside of the sound amplifying piece 2 is plated with zinc to form a smooth bright surface, which plays a better role in refracting sound waves. The sound amplifying hole 11 is filled with a filter screen 3 woven from metal wires. The filter screen 3 is arranged to prevent foreign matter from entering the shell 1 through the sound amplifying hole 11 and damaging the sound producing element.

[0025] According to Figure 3 As shown, the outer wall of the open end of the shell 1 is provided with a fixing lug 4, the fixing lug 4 is provided with a through hole, and the through hole is riveted with a screw sleeve 5 made of metal material. The fixing lug 4 is used to better fix the shell 1 on the electronic product. The screw sleeve 5 made of brass material is used to improve the service life of the screw hole on one hand, and to produce slip wire on the other hand, so that the screw cannot be removed from the fixing lug 4. In addition, it should be noted that the height of the screw sleeve 5 is less than the height of the fixing lug 4, and the inner diameter of the bottom of the through hole is equal to or less than the inner diameter of the screw sleeve 5. The screw is wrapped by the shrinkage of the plastic itself to prevent the screw from falling off.
