Abstract
Description
Technical Field
[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to a highly integrated waterproof loudspeaker. Background Technology
[0002] Traditional megaphones present numerous problems when used with fire-fighting breathing apparatus. Firstly, fire scenes often involve large amounts of water, smoke, and dust, and ordinary megaphones, lacking waterproofing, are easily damaged by moisture, leading to communication failures. For instance, in high-rise building fires, firefighters may need to traverse sprinkler systems or operate in flooded environments; existing non-waterproof megaphones cannot function properly in such situations, severely impacting the coordination of rescue operations.
[0003] Secondly, in dimly lit fire scenes, firefighters need additional lighting equipment to ensure safe operation and observation of the surrounding environment. Most existing loudspeakers lack lighting capabilities, or even if they do, their brightness is insufficient to meet the lighting needs of a fire scene, and the direction and range of the lighting do not align well with the firefighters' field of vision. For example, when searching for trapped individuals, dim lighting can hinder firefighters from spotting people hidden behind obstacles, reducing rescue efficiency.
[0004] Currently, the equipment used in firefighting breathing apparatus on the market has relatively limited functionality. For example, some equipment only has a loudspeaker function, requiring firefighters to also carry electronic pressure gauges to monitor the pressure inside the breathing apparatus. This increases the complexity and weight of the equipment, hindering the firefighters' agility. Moreover, during tense rescue operations, operating different equipment separately can easily distract firefighters and affect operational efficiency.
[0005] The biggest challenge in multifunctional integrated design is how to integrate multiple PCBs that perform multiple functions into a small and compact space, while also making it easy to add waterproofing measures. Utility Model Content
[0006] The present invention provides a highly integrated waterproof loudspeaker that integrates multiple PCBs performing multiple functions into a small and compact space, and also has a certain degree of waterproof performance.
[0007] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:
[0008] The six sidewalls of the upper shell (1) form a hexagon that matches the shape of the rear shell (9) so that the rear shell (9) and the upper shell (1) can form a sealed internal cavity after installation. The top of the internal cavity is the inner surface of the bottom of the upper shell (1), the side of the internal cavity is the inner surface of the six sidewalls of the upper shell (1), and the bottom of the internal cavity is the inner surface of the rear shell (9).
[0009] The front PCB (3) is mounted close to the inner surface of the side wall of the upper shell (1), the main PCB 1 (3 (1)) in the front PCB (3) is mounted close to the inner surface of the bottom of the upper shell (1), and the rear PCB (7) is mounted close to the inner surface of the rear shell (9).
[0010] The front of the main PCB1 (3(1)). A first waterproof seal (2) is provided between it and the upper shell (1);
[0011] A second waterproof seal (14) is provided on the contact surface between the upper shell (1) and the rear shell (9).
[0012] The highly integrated waterproof megaphone provided by this utility model embodiment improves the integration of megaphones used in emergency rescue sites. It can integrate multiple PCBs in a small and compact space and implement waterproof performance, thereby facilitating the realization of multiple functions on the megaphone through the integrated high-speed PCB.

On the upper shell top cover (1(1)), in the central area surrounded by the three upper shell secondary top covers (1(5)), there are shell top cover sound outlets (1(2)) and upper shell secondary top cover function button arrangement areas (1(7)).

Multiple PCBs can be integrated into a small, compact space and waterproofed, allowing the loudspeaker to perform multiple functions through the integrated PCBs, such as waterproofing and high-brightness lighting. For example, in practical applications, real-time communication is required during firefighting operations. While some existing loudspeakers have some communication capabilities, they lack push-to-talk (PTT) functionality. PTT allows firefighters to control communication more easily, avoiding noise and unnecessary interference in the communication channel, achieving clear and efficient voice communication. However, the shortcomings of existing equipment prevent firefighters from quickly and accurately conveying information when communication is needed. Existing fire-fighting breathing apparatus equipment has significant deficiencies in waterproofing, lighting, and functional integration (including electronic pressure gauge, PTT, and loudspeaker functions), seriously affecting the efficiency and safety of fire rescue operations. Therefore, there is an urgent need for an improved loudspeaker that integrates multiple functions and features waterproofing and high-brightness lighting for fire-fighting breathing apparatus.
