DETAILED DESCRIPTION

[0021] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0023] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0024] Reference Figures 1 to 3A drone loudspeaker includes a drone body 1, two sound baffles 2 and a loudspeaker box 3; the outer surface of the sound baffle 2 is sprayed with any of the following coating materials: ceramic coating or metal powder coating; both ceramic coating and metal powder coating have high wear resistance and corrosion resistance, and can maintain the integrity and stability of the sound baffle 2 in complex environments, thereby ensuring the quality of voice transmission. In addition, these two coatings also have high acoustic performance, can reflect, absorb or scatter sound waves of different frequencies, and further improve the clarity and distance of voice transmission.

[0025] The drone body 1 includes a first supporting foot 11 and a second supporting foot 12 in a "U"-shaped structure, two sound baffles 2 are sequentially mounted on the first supporting foot 11 and the second supporting foot 12, and a speaker box 3 is arranged at the bottom of the drone body 1; a first speaker 31 and a second speaker 32 are arranged on the speaker box 3, wherein the sound output end of the first speaker 31 faces the sound baffle 2 on the first supporting foot 11, and the sound output end of the second speaker 32 faces the sound baffle 2 on the second supporting foot 12, and sound transmission strip grooves 21 are arranged on the two sound baffles 2, and the sound transmission strip grooves 21 are mainly used to transmit the sound waves emitted by the first speaker 31 and the second speaker 32 downward.

[0026] By placing the first speaker 31 in the speaker box 3 toward the sound baffle 2 of the first support leg 11 and the second speaker 32 toward the sound baffle 2 of the second support leg 12, air resistance and sound wave scattering can be effectively prevented, and a sound transmission strip groove 21 is opened on the sound baffle 2. The sound transmission strip groove 21 is used to transmit the sound waves emitted by the first speaker and the second speaker downward, so that the sound waves can be propagated more concentratedly, thereby improving the effect and distance of voice propagation, thereby improving the problem of limited voice propagation distance due to the influence of air resistance and sound wave scattering during the voice propagation process of the drone loudspeaker.

[0027] Reference Figures 1 to 3 In order to further increase the rebound effect of the sound baffle 2, the sound direction of the first speaker 31 is aligned with the sound baffle 2 on the first support leg 11 at an "acute angle", and the sound direction of the second speaker 32 is aligned with the sound baffle 2 on the second support leg 12 at an "acute angle". Through the acute angle alignment, the sound waves will encounter fewer obstacles and resistances during the propagation process, reducing the scattering and energy loss of the sound waves; at the same time, the acute angle alignment can also effectively focus the sound waves in the sound transmission bar groove 21. When the first speaker 31 is aligned with the sound baffle 2 on the first support leg 11 and the second speaker 32 is aligned with the sound baffle 2 on the second support leg 12 at an acute angle, the sound waves will be refracted and reflected when propagating in the sound transmission bar groove 21, so that the sound waves can be transmitted downward more concentratedly. This focusing effect can increase the intensity and density of the sound waves, thereby improving the effect of voice propagation.

[0028] Reference Figures 1 to 3 Two connecting through holes 33 are provided at one end of the speaker box 3 away from the drone body 1, and two connecting bolts 34 are respectively provided on the two connecting through holes 33; and a threaded hole 13 aligned with the connecting through hole 33 is provided at one end of the drone body 1 facing the speaker box 3, so that the connecting bolt 34 passes through the connecting through hole 33 and is threadedly connected with the threaded hole 13, thereby achieving the effect of fixing the speaker box 3 on the drone body 1. By using two connecting through holes 33 and two connecting bolts 34, the speaker box 3 can be doubly fixed to the drone body 1, ensuring that the speaker box 3 is firmly fixed to the drone, and can maintain a stable connection even in the case of movement or vibration, which helps to reduce unnecessary vibration and swing, thereby improving the transmission effect of sound quality.

[0029] Reference Figures 1 to 3 The drone body 1 includes four propellers 14 and four drive motors 15. The propellers 14 are arranged at the output ends of the drive motors 15 to enable the drone body 1 to fly. The drive motors 15 provide power, and the rotation speed and direction of the propellers 14 are controlled, so that the drone can fly stably in the air. The propellers 14 are directly arranged at the output ends of the drive motors 15, which can simplify the structure of the drone and reduce the number of components. The compact design can reduce weight and aerodynamic resistance, thereby improving flight efficiency and control performance.

[0030] Reference Figures 1 to 3 A spherical lamp 16 is provided at one end of the drone body 1 away from the speaker box 3, and the spherical lamp 16 is mainly used for lighting. The spherical lamp 16 emits light to illuminate the surrounding environment to meet the lighting needs of the drone when performing tasks. This is very important for operating drones at night or under limited light conditions, and can enhance the operator's visual ability and the accuracy of task execution. At the same time, it can also provide warnings for other aircraft, ground personnel or equipment. Especially in low visibility environments or complex airspaces, the spherical lamp 16 can be used as a logo and warning signal to reduce the risk of accidents and improve the safety of drones.

[0031] Reference Figures 1 to 3 The drone body 1 also includes a first camera 17, which is arranged on the side of the spherical light 16. The first camera 17 is used to shoot the content in the horizontal direction of the drone. By arranging the first camera 17 on the drone body 1, it is possible to shoot and record the environment around the drone body 1. Since the first camera 17 is arranged on one side of the spherical light 16, the first camera 17 can shoot the content in the horizontal direction of the drone, so that the drone can capture more information and data when performing tasks, thereby improving the effectiveness and efficiency of its task execution.

[0032] Reference Figures 1 to 3 A mounting opening 35 is provided on the end face of the speaker box 3 away from the drone body 1, and a second camera 36 is installed in the mounting opening 35. The second camera 36 is mainly used to shoot the content in the vertical direction of the drone. By installing the second camera 36 on the end face of the speaker box 3, the drone can shoot its content in the vertical direction. The second camera 36 can capture the scene below the drone, including the ground, buildings, vehicles, etc., so that the drone can obtain a more comprehensive perspective and information when performing a task, thereby improving the accuracy and efficiency of task execution.

[0033] The implementation principle of a drone loudspeaker in an embodiment of the present application is as follows: first, a sound baffle 2 is respectively mounted on the first supporting foot 11 and the second supporting foot 12 of the drone body 1, and then the loudspeaker box 3 is installed under the drone body 1, and the first loudspeaker 31 on the loudspeaker box 3 is directed toward the sound baffle 2 of the first supporting foot 11, and the second loudspeaker 32 is directed toward the sound baffle 2 of the second supporting foot 12, so as to achieve the effect of preventing air resistance and sound wave scattering, and then the sound waves emitted by the loudspeaker are transmitted downward through the sound transmission strip groove 21 of the sound baffle 2, so that the sound waves can be propagated more concentratedly, thereby improving the effect and distance of voice propagation, thereby improving the problem of limited voice propagation distance due to the influence of air resistance and sound wave scattering during voice propagation of the drone loudspeaker.

[0034] Secondly, align the first speaker 31 with the sound baffle 2 on the first support leg 11 at an "acute angle", and then align the second speaker 32 with the sound baffle 2 on the second support leg 12 at an "acute angle". Through the acute angle alignment, the sound waves will encounter fewer obstacles and resistances during the propagation process, which can effectively reduce the scattering and energy loss of the sound waves.

[0035] Next, a connecting through hole 33 is opened at the end of the loudspeaker box 3 away from the drone body 1, and a connecting bolt 34 is arranged on the connecting through hole 33; a threaded hole 13 aligned with the connecting through hole 33 is opened at the end of the drone body 1 facing the loudspeaker box 3; wherein the connecting bolt 34 passes through the connecting through hole 33 and is threadedly connected with the threaded hole 13, so that the loudspeaker box 3 can be fixed to the drone body 1, ensuring that the loudspeaker box 3 is firmly fixed on the drone body 1.

[0036] Then, the drone body 1 includes a rotating propeller 14 and a driving motor 15. The rotating propeller 14 is arranged on the output end of the driving motor 15 to make the drone body 1 fly; and a spherical lamp 16 is arranged at one end of the drone body 1 away from the shouting box 3. The illumination of the spherical lamp 16 enhances the operator's visual ability and the accuracy of task execution.

[0037] Finally, the drone body 1 includes a first camera 17, which is arranged on the side of the spherical light 16 and is used to shoot the content in the horizontal direction of the drone. The speaker box 3 is provided with a mounting opening 35 on the end surface away from the drone body 1, and a second camera 36 is installed in the mounting opening 35, and the second camera 36 is used to shoot the content in the vertical direction of the drone, thereby realizing the shooting and recording of the environment around the drone body 1.
