The submersible underwater speakers are connected to a sound source and a power source that are controlled from the watercraft. The watercraft mounted with the underwater sound system of the present invention allows it to be used in a waterbody such as pond, lake, river, sea or the like so that some underwater activities can be conducted while the system is being used to play music or voice of the user or any recorded sound that may be useful for attracting aquatic animals, or preventing any accidents, or supporting divers or any such activities.

Description

FIELD OF THE INVENTION

The present invention relates generally to an underwater sound system. More so, the present invention relates to an underwater sound system for watercraft.

BACKGROUND OF THE INVENTION

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to provide additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.

The fact that sound waves are propagated through water has been known for many years. There are many audio devices which are water resistant, some are submersible and capable of transmitting sound underwater.

Numerous attempts have been made and several prior art devices are known for devices that are submersible and capable of transmitting sound underwater to be used in swimming pool, water bodies, speaker for divers, fish attracting submersible speakers, etc. Even though these innovations may be suitable for the specific purposes to which they address, however, they would not be as suitable for the purposes of the present invention.

For example, U.S. Pat. No. 3,174,129 to Laughlin et al. discloses an underwater sound transmitter with a microphone which is suitable for use by a diver.

U.S. Pat. No. 5,142,508 to Mitchell et al. describe aquatic alarm and sound systems for producing high-fidelity sound underwater to signal unauthorized activity in a water body.

U.S. Pat. No. 6,545,948 to Jiang teaches 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 submersible loudspeaker is designed to be used in swimming pools, spas, hot tubs, bathtubs, saunas, ponds, lakes, or other bodies of water.

U.S. Pat. No. 8,792,306 to Palmer et al. discloses a submersible speaker adapted to emit a pre-recorded sound for attracting an aquatic animal to assist fishing.

U.S. patent Ser. No. 10/412,948 to Burton discloses a fishing assistive device comprising a submersible speaker with sonar transducers that is adapted to determine fish location in the underwater environment.

U.S. patent Ser. No. 11/051,100 to D'Ascanio et al. discloses a smart, under/over water speaker system comprising a unique speaker which provides sound both above and below the water surface.

It is apparent now that numerous innovations that are adapted to a variety of submersible speakers have been previously developed in the prior art that are adequate for various purposes. Furthermore, even though these innovations may be suitable for the specific purposes to which they address, accordingly, they would not be suitable for the purposes of the present invention as heretofore described to be used in a watercraft. Thus, an underwater sound system for watercrafts is needed.

In typical deployment of the watercraft 300 in the water body, the proximal plate edge 306 of the speaker plate 300 may be at or near the waterline 304. The distal plate edge 308 may be submerged beneath the water and the outer plate surface 310 may face away from the watercraft 200 in a first, lowered position of the speaker plate 300, shown in solid lines in FIG. 6, and lifted out of the water with the outer plate surface 310 facing toward the watercraft 200 in a second, raised position of the speaker plate 300, shown in dashed lines in FIG. 6.
