[0021] In order to make the above objectives, features and advantages of the present application more clear and comprehensible, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the purpose of description, only the parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] The terms "comprising" and "having" and any variations thereof in the present application are intended to cover non-exclusive inclusion. For example, a process, system, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally further comprises steps or units not listed, or optionally further comprises other steps or units inherent to these processes, systems, products or devices.

[0023] In the present application, the phrase "embodiments" means that the specific features, structures or characteristics described in conjunction with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it independent or alternative to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0024] As Figure 1 shown (the unmanned aerial vehicle is not shown in Figure 1 , which can be connected through quick release seat 1), the embodiments of the present application provide a shouting loudspeaker system based on unmanned aerial vehicle, which combines the flexibility of unmanned aerial vehicle and the shouting function of loudspeaker device, and communicates and controls through remote server. This system can be used in various occasions, such as emergency rescue, large event management, traffic control, etc., where information needs to be quickly and accurately transmitted.

[0025] Specifically, the unmanned aerial vehicle is the core part of the system, which is responsible for flying in the air and carrying the loudspeaker device to the designated position. The unmanned aerial vehicle can be equipped with advanced navigation system to ensure that it can fly according to the predetermined route and height. The unmanned aerial vehicle can also be provided with automatic obstacle avoidance function to avoid collision with obstacles during flight.

[0026] The loudspeaker device is another key part of the system, which is responsible for generating and transmitting sound information. The loudspeaker device has adjustable volume and tone to adapt to different environments and needs. The loudspeaker device may also have waterproof, dustproof and other characteristics to ensure normal work in bad weather conditions.

[0027] A pair of quick-release seats 1 are provided on the unmanned aerial vehicle and the horn device, which allows the horn device to be quickly and easily installed on the unmanned aerial vehicle and easily removed from the unmanned aerial vehicle. The quick-release seats 1 are each equipped with a connector, which is used to establish an electrical connection between the unmanned aerial vehicle and the horn device to ensure that the sound signal can be smoothly transmitted.

[0028] The model of the connector is J30J-15, which contains DC power supply and network interface. Specifically, the model of the connector of the unmanned aerial vehicle is J30J-15ZKP, which contains a 30cm wire, and the other end of the cable is connected with the XD121 socket. The model of the connector of the horn device is J30J-15TJL, which ensures the reliability and stability of the connection. It contains a 30cm wire, and the other end of the cable is connected with the audio chassis.

[0029] The remote server is communicatively connected with the unmanned aerial vehicle and the horn device, and is used to control the operation of the entire system. The remote server has a real-time monitoring function and can display the position, height, speed and other information of the unmanned aerial vehicle. The remote server can also be used to record and play the content of the shouting, as well as adjust the volume and tone of the horn device and other parameters.

[0030] Further, a moving coil speaker 2 is provided in the horn device, and the shouting is performed through the speaker. The moving coil speaker 2, also known as the electric speaker, works on the principle of electromagnetic induction. When an electric current passes through a coil placed in a permanent magnetic field, the coil will be subjected to the force of the magnetic field and vibrate, thereby pushing the speaker diaphragm to vibrate and emit sound. In the shouting horn system based on the unmanned aerial vehicle, the application of the moving coil speaker 2 can produce relatively pure sound, which is particularly important for the shouting system that needs to clearly convey information. The moving coil speaker 2 has a fast response speed to audio signals and can quickly respond to the instructions of the unmanned aerial vehicle to realize instant shouting. The moving coil speaker 2 can process audio signals of different power and adapt to the sound demand in different scenarios.

[0031] Specifically, the moving coil speaker 2 is an inner magnetic speaker. The inner magnetic speaker is a type of moving coil speaker 2, characterized by a permanent magnet wrapped inside the speaker, forming a closed magnetic field. This design makes the speaker more compact, making it easier to install and use in limited space.

[0032] Because the permanent magnet is wrapped inside, the inner magnetic speaker has less external magnetic interference and is not affected by external magnetic fields, ensuring the stability of the sound. The inner magnetic speaker avoids the damage that external exposed magnets may cause to surrounding electronic devices or magnetic materials. The compact design makes the inner magnetic speaker easier to integrate with other electronic devices or systems, suitable for various application scenarios.

[0033] Further, in the shouting speaker system of the unmanned aerial vehicle, the horn device serves as the sound emitting component, and the internal electronic elements thereof will generate a large amount of heat during high-intensity work. In order to ensure stable operation of the system and prolong the service life, effective heat dissipation measures must be taken. Therefore, a heat sink 3 is specially designed in the system for timely removal of the heat generated inside the horn device.

[0034] The working principle of the heat sink 3 is mainly based on heat conduction and air cooling. The heat conduction is that the heat sink 3 is in close contact with the heating elements inside the horn device, and the heat is conducted from the heating elements to the heat sink 3 through a material with good heat conduction performance such as metal. The air cooling is that the surface of the heat sink 3 is usually designed with heat dissipation fins or air ducts to increase the heat dissipation area and air flow efficiency. When the unmanned aerial vehicle is flying, the airflow generated or the additional fan can accelerate the air flow, and the heat on the heat sink 3 is taken away through the air cooling mode, so as to achieve the heat dissipation effect.

[0035] By adopting the combination of heat conduction and air cooling, the temperature inside the horn device can be quickly reduced, and the system can still operate stably under high-intensity work. Effective heat dissipation measures can prevent damage to electronic elements due to overheating, thereby prolonging the service life of the horn device. The stable temperature environment helps to improve the overall stability of the system and reduce the performance fluctuations caused by temperature changes. In the shouting speaker system of the unmanned aerial vehicle, the design of the heat sink 3 not only reflects the strict requirements for the performance of the system, but also reflects the care for the user experience. Through the efficient heat dissipation measures, the system can maintain stable performance output in various complex environments, ensuring that the intelligibility and loudness of the shouting speaker are not affected. This is particularly important for application scenarios that require long-term and high-intensity use of the shouting speaker system.

[0036] Further, the embodiment of the present application also designs a horn 4 in front of the moving coil loudspeaker 2 and sets an accelerator in the throat part of the horn 4. The horn 4 is an acoustic device, and its main function is to amplify sound and change the directivity of sound. In the shouting speaker system, the horn 4 can ensure that the sound is transmitted to a farther distance with higher volume and clearer sound quality.

[0037] The design of the horn 4 generally needs to consider multiple factors, including its shape, size, and material. The shape and size affect the focusing and diffusion of sound, while the material affects the transmission efficiency and tone color of sound. In this system, the horn 4 is designed to match the dynamic cone speaker 2 to ensure that the sound can be smoothly transmitted from the speaker to the horn 4 and undergo amplification and directivity adjustment through the horn 4. In addition, the accelerator in the throat part of the horn 4 is a key design element. The accelerator's role is to accelerate the propagation of sound and enhance the coupling effect of sound and air. By accelerating the propagation of sound, the accelerator can ensure that the sound maintains a high energy and clarity when passing through the horn 4. At the same time, the accelerator can also improve the interaction between sound and air, making the sound more stable during transmission, reducing distortion and attenuation. In practical applications, this megaphone system with horn 4 and accelerator can be widely used in various occasions that require long-distance sound propagation. For example, in emergency rescue, outdoor performances, sports events, etc., this system can ensure that the sound is clearly transmitted to the audience or listener's ear, improving the efficiency and accuracy of information transmission.

[0038] Specifically, through the TCP protocol, the unmanned aerial vehicle sets the megaphone volume by using the JSON field in the network packet with the loudspeaker device. After the unmanned aerial vehicle and the loudspeaker device are powered on, the system automatically plays the voice file in the fixed path by default. After the server sends the megaphone file to the unmanned aerial vehicle, the unmanned aerial vehicle sends the voice packet to the loudspeaker device through the standard TCP protocol, and the loudspeaker device receives the voice packet and plays it in real time. The handheld microphone transmits the real-time megaphone to the remote server, which is transmitted to the unmanned aerial vehicle in real time, and the unmanned aerial vehicle transmits it to the loudspeaker device in real time, realizing one-way intercom megaphone. Through TCP, the unmanned aerial vehicle receives the network packet from the remote server, parses the play count and the play interval of each time, and controls the play count and the time interval of each play of the loudspeaker device. Since the embodiment of the present application realizes real-time playback by transmitting the voice file from the unmanned aerial vehicle to the loudspeaker device, when the unmanned aerial vehicle stops transmitting the voice file to the loudspeaker device, the loudspeaker device stops playing.
