Marine speakers are commonly used on marine vehicles such as yachts, jet skis, ships, etc., so long-term exposure to wet steam or salt spray is required, and even harsh environments such as rain or flooding may occur.
Most marine speakers will design the speaker’s interior into a closed structure to prevent the speaker from entering the water.
When the speaker is working for a long time in a closed environment, it can’t be quickly dissipated, so that it will generate high temperature inside. When the internal temperature reaches the melting point of the glue or the part, the speaker will be damaged, which will affect the performance and service life of the product.
To improve the heat dissipation of the voice coil, the industry has adopted some structures to enhance the heat dissipation. However, considering waterproofing, it is still impossible to achieve both waterproof and heat dissipation.
