Improvement in Waterproof Effect of Speaker Enclosure

Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 235)


Currently, demands for the outdoor broadcasts and concerts are increasing. Due to certain circumstances of outdoor spaces, loud speakers can be easily damaged by rain, which might cause unnecessary vibration and noise. In this paper, experimental approaches to improve waterproof-effect of the movable loud speaker have been investigated. Acoustic experiments to study the water-proof effect of enclosure based on the three different types of material were performed. Analyzing and comparing acoustic characteristics such as the frequency and sound pressure, we have shown that FRP has the most outstanding performance on the water-proof effect of loudspeaker. Also, these results represent that water-proof loudspeaker can be manufactured for mass products.
