Abstract: A water dancing speaker is disclosed. The water dancing speaker comprises a housing assembly, a liquid spraying device, a liquid spraying power supplying device, a liquid column steering device, a driving device and an audio device. The housing assembly is formed with an exhibiting cavity, a partition cavity and an audio cavity, and the liquid spraying device can produce a liquid column. The water dancing speaker of the present disclosure can produce liquid columns that vary rhythmically with the audio characteristics of the played tracks, which improves the ornamental effect of the speaker.

Abstract: The present invention provides a floating and waterproof sound box including a bottom house, the bottom house has a two-layer structure and includes an inner rear house located in an inner layer and an outer rear house located in an outer layer, the inner rear house is entirely enclosed, the outer rear house has a two-layer structure, at least one water inlet is defined in an outer layer of the outer rear house, and a water storage space is defined between the outer layer and in an inner layer of the outer rear house. The floating and waterproof sound box of the present invention can float over flowing water without being overturned or sinking and the inner rear house is entirely enclosed so that water penetration is avoided.

Abstract: A water jet device and a water dance speaker comprising the water jet device are disclosed. The water jet device comprises a base container, a drive unit and fans driven by the drive unit, the drive unit being mounted externally to a bottom of the base container, while the fans internally to the bottom of the base container. A cover plate, disposed on the base container to engage therewith, comprises via holes thereon and coordinates with the base container to form a chamber to contain liquids. On the side of the cover plate away from the base container are formed protrusions vertical to the cover plate, a first via hole penetrating each of the protrusions. The present invention provides a water jet device capable of recycling water resources and preventing water leak. Therefore, the water jet device as disclosed is safe in use and possesses practical applicability.

Abstract: The present disclosure discloses a sound box and an audio playing device comprising the sound box. The sound box comprises a housing and a transparent cover fixedly connected with the housing. The sound box further comprises a transparent base fixedly connected with the transparent cover, a water spraying plate provided with a spray nozzle, and a fan blade for draining off water.
