In the embodiment of the present application, the shell 1 of the floating water jet speaker has a sound cavity 101, that is, the shell 1 has an internal cavity, so when the water jet speaker is placed on the water surface, it can float on the water surface to realize the floating function . And when the water spray speaker is placed on the water surface, the water spray pump 301 can extract water and pump it into the water spray pipe 302, and the water is finally sprayed from the outlet of the water spray pipe 302 to achieve the effect of water spray.

The water spray pipe 302 penetrates through the upper casing 103 and is sealedly connected with the upper casing 103 at the first abdication hole 1031; at the same time, the bottom of the water spray pipe 302 is sealed and connected with the inner surface of the lower casing 102, and surrounds the water inlet hole 1022, and then The water spray pipe 302 is sealedly connected with the housing 1 . The water jet pump 301 is installed in the recessed accommodating groove 1021 of the lower casing 102 , although it is on one side of the outer surface of the lower casing 102 , it will not protrude from the surface of the lower casing 102 .

The floating water jet speaker also includes a hydrophobic layer 13 disposed on the water blocking shell 12. The hydrophobic layer 13 is located on the side of the water blocking shell 12 that faces away from the speaker 2. Before part of the water hits the water blocking shell 12, most of the water flows along the hydrophobic surface. The layer 13 flows down, further reducing the amount of water that passes through the water retaining shell 12 to the horn 2 .

Please refer to FIG. 2-FIG. 3. As another specific embodiment of the floating water jet speaker provided by the present application, the floating water jet speaker further includes a top seat 14 disposed on the horizontal top surface 1033, and the top seat 14 is provided with a water jet The second escape hole 1401 through which the pipe 302 passes; Therefore, when the water falls from a height, it will not touch the position where the water blocking shell 12 and the top seat 14 are clamped, and it is not easy to enter the interior of the water jet speaker through the gap, and can only slide down along the surface of the hydrophobic layer 13, with only a small part of it.
