A submersible loudspeaker including an electro-acoustic transducer which accepts the electrical signal from the audio system and delivers sound waves generated by piezoelectric elements in proportion to the signal applied to it. The speaker primarily comprises at least one transformer operatively connected to a piezoelectric ceramic element to form a sound element array, contained within a waterproof sealing body comprising a diaphragm for transducing sound waves to the receiving medium, and encased within a shell or housing. The piezoelectric element is in contact with the diaphragm that directly contacts the transfer medium. The submersible loudspeaker is designed to be used in swimming pools, spas, hot tubs, bathtubs, saunas, ponds, lakes or other bodies of water. A system would include a submersible loudspeaker used in conjunction with an air speaker on a single audio output system, so that a listener can simultaneously listen to music underwater and in the surrounding air.
