<p>The present invention provides apparatuses and methods for alleviating impact of underwater pressure upon submersible devices and emitters. An interior space of the casing (104) of a submersible device may be filled up with fluid to reduce the impact of underwater pressure. The submersible device may further comprise a pressure adjusting bladder (102) attached to the casing through a structure that permits flow of fluid expansion due to changes in surrounding pressure or temperature. The submersible device may also comprise a special type of fluid and specially designed internal components so that the presence and flow of the fluid within the device do not affect the performance of the components.</p> |
