A "water speaker" refers to an audio device that works by using water instead of air as its medium for sound transmission. This innovative technology, also known as a hydroacoustic speaker, employs the unique acoustical properties of water to produce clearer and more powerful sound waves than traditional speakers. The back of a water speaker typically houses essential components such as the water reservoir, transducer, and amplifier, which work together to generate high-quality audio output underwater.
