AI Technical Summary

Technical Problem

Existing underwater loudspeakers rely on rigid structures to support water pressure, resulting in an exponential decrease in vibration amplitude with water depth, insufficient low-frequency response, and rigidity of the vibration system in deep water environments, which makes it impossible to effectively output sound waves and meet the sound wave output efficiency and stability requirements of unconventional underwater fields.

Method used

The system employs a multi-compartment collaborative control mechanism, including a sound-generating compartment, a gas buffer compartment, and a gas storage compartment. Combined with displacement sensors, pressure sensors, and a servo control system, it regulates gas flow through electronic valves to achieve precise control of sound wave frequency, amplitude, and pressure, ensuring stable operation of the system in different water depth environments.

Benefits of technology

It achieves efficient and stable sound wave output, improves low-frequency response and sound energy conversion efficiency, adapts to different water depth environments, ensures system safety, and breaks through the limitations of water depth adaptability and working depth.
