Waterproof speakers are often used in outdoor venues such as large-scale performances, outdoor sports stadiums, parks, and school playgrounds. These speakers have waterproof functions and can withstand the harsh test of outdoor wind and rain. As an important sound producing component in waterproof speakers, water has a significant impact on the speaker. Once water enters, the speaker is likely to lose its function. If the speaker undergoes IP67 waterproof rating testing, it can protect the speaker from rainwater damage.
