Development and Performance Analysis of a Miniature Plasma Sound Source System

At present, the device of plasma sound source is huge, which is not favorable for the outfield experiments, so there is an urgent need for a plasma sound source with a small size, lightweight, and good portability. This paper presents a design scheme of a miniature plasma sound source. With the MSP430 series processor as the core, a new system is designed, which combines a control module, power supply module, high-voltage generating module, energy storage module, discharge module, trigger module, etc. Some functions, such as switch control, cycle control, and pulse coding, are realized in this system. The new system enhances the controllability of the plasma sound source while meeting the practical needs. The prototype is developed and tested, and the results show that this system performs well.
