Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a megaphone, including...

[0029] The loudspeaker warning mechanism 200 includes a housing 210, which includes a top cover 211 and a bottom plate 213. The top cover 211 is locked to the top of the bottom plate 213.

[0030] Please see Figure 3 and Figure 4 The housing 210 contains a loudspeaker warning component 220, which includes a horn 221 mounted on both sides of the base plate 213. The bottom of the horn 221 is connected to a sound amplification channel 224, which is arc-shaped and faces the center of the base plate 213. A strobe warning light 223 is mounted on the outside of the horn 221 and is symmetrically mounted on both sides of the base plate 213. The dual-sided layout helps to achieve a better stereo effect and improve the propagation range and clarity of the sound in different directions. The arc-shaped sound amplification channel 224 can effectively gather and guide sound energy, making the sound propagate larger and farther.

[0031] Mounting plates 214 are fixedly connected to both sides of the base plate 213. The mounting plates 214 and the base plate 213 are connected in a figure-eight shape. A circular through hole is opened inside the mounting plate 214. Side covers 212 are fixedly connected to both sides of the top cover 211. A through hole is opened in the middle of the side cover 212. The shape of the top cover 211 and the side cover 212 is the same as that of the base plate 213 and the mounting plate 214. The top cover 211 and the side cover 212 are wrapped around the outside of the base plate 213 and the mounting plate 214. Connecting posts 215 are provided on both sides of the tail of the base plate 213 and the top cover 211. The connecting posts 215 lock the top cover 211 and the base plate 213. The connecting posts 215 are threaded. The base plate 213 and the top cover 211 are snap-fit ​​connected, which is convenient for disassembly and installation, and facilitates the maintenance and repair of the equipment.

[0032] Speakers 221 are mounted on the top of the mounting plate 214. The top of the speaker 221 corresponds to the circular through hole of the side cover 212, and the sound-generating part of the speaker 221 corresponds to the through hole in the middle of the mounting plate 214. This allows the sound to directly enter the amplification channel 224, reducing sound loss during propagation and improving sound propagation efficiency and quality. The sound propagation range can be expanded by moving the drone body 100 up and down, without the need for repeated movement of the drone body 100.

[0033] The loudspeaker channel 224 is fixedly installed at the bottom of the mounting plate 214, with two loudspeaker channels 224 arranged symmetrically. Corner plates 225 are provided at the four corners of each loudspeaker channel 224. The corner plates 225 are arc-shaped, and a channel opening 226 is provided at the lower end of each corner plate 225. The channel opening 226 is angled, facing the lower sides of the base plate 213. This angled arrangement allows the sound to be more concentrated and propagated to the lower sides of the device, improving sound coverage in the target area. Especially when a drone is equipped with a megaphone, it can better transmit sound to the ground target area. The circuit board 227 also includes a Beidou module and a 4G communication module.

[0034] A side mounting plate 222 is fixedly mounted on the outer end of the mounting plate 214. A strobe warning light 223 is fixedly mounted on the outer side of the side mounting plate 222. A through hole is provided on the outer side of the side cover 212 to mate with the strobe warning light 223, which is embedded in the outer side of the side cover 212. A circuit board 227 is mounted on the upper middle part of the base plate 213. The circuit board 227 is electrically connected to the speaker 221 and the strobe warning light 223. The circuit board 227 serves as the control core of the entire megaphone, responsible for controlling the sound output of the speaker 221 and the flashing mode of the strobe warning light 223. The circuit board 227 integrates various electronic components, such as an audio amplifier, controller, and power management chip.

[0035] Please see Figure 5 and Figure 6 The circuit board 227 is equipped with an audio input interface for connecting external audio sources (such as microphones, audio players, etc.). The audio signal is first amplified and filtered by a preamplifier to remove noise and interference signals, and then converted from analog audio signal to digital signal by an analog-to-digital converter (ADC). The circuit board 227 also includes a communication interface circuit. Communication interfaces include serial ports (such as UART), SPI interfaces, or USB interfaces. Through these interfaces, the megaphone can exchange data with the drone's flight control system or other control modules. Customized program code can be written within the megaphone's circuit board 227. Remote control of the megaphone can be achieved through an SDK. The communication interface of the circuit board 227 connects to the corresponding communication interface of the drone body 100, enabling bidirectional data transmission.

[0036] Please see Figure 1 A drone includes a loudspeaker, a drone body 100, the middle of the drone body 100 being located below a shell 210, the bottom of the shell 210 being engaged with the top of the drone body 100, and loudspeaker warning components 220 being located on both sides of the drone body 100, with the loudspeaker warning components 220 being engaged with the sides of the drone body 100.

[0037] Working principle: When a message needs to be delivered, the circuit board 227 receives a signal and drives the speaker 221 to operate. The sound generated by the speaker 221 is transmitted through the through-hole in the center of the mounting plate 214, and then enters the bottom amplification channel 224. The arc-shaped structure of the amplification channel 224 converges and guides the sound, concentrating the sound energy in a specific direction. The arc-shaped corner plate 225 further optimizes the sound propagation path within the amplification channel 224, while the tilted channel opening 226 allows the sound to diffuse at a certain angle towards the lower sides of the base plate 213, thereby increasing the sound coverage and ensuring that the message can be clearly transmitted to the target area at the drone's flight altitude.

[0038] Circuit board 227 also controls the operation of strobe warning light 223. Depending on different mission requirements (such as emergency rescue, traffic control, etc.), circuit board 227 can be set with different flashing modes and frequencies, causing strobe warning light 223 to emit corresponding warning lights. When the drone flies over the target area, strobe warning light 223 starts working; its strong flashing light can attract the attention of surrounding personnel and vehicles from a distance, working in conjunction with the announcements from loudspeaker 221 to complete warning and command tasks.

[0039] The loudspeaker is mounted on the drone body 100 and is securely connected to the drone body 100 via a locking mechanism on the housing 210. The drone's control system communicates with the loudspeaker's circuit board 227. Operators on the ground send commands to the drone via a remote control or other control devices. The drone transmits these commands to the loudspeaker's circuit board 227, thereby controlling parameters such as the content and volume of the loudspeaker 221 and the flashing mode of the strobe warning light 223. This enables the drone and loudspeaker to work together, allowing the loudspeaker to accurately and efficiently perform various tasks during the drone's flight.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
