Sprayers 221 for liquid spraying are disposed on and protrude from the sprayer plate 22, and a central position of each of the sprayers 221 is provided with a liquid spraying hole running through the sprayer plate 22. In this embodiment, the sprayers 221 are preferably arranged on the sprayer plate 22 around the center of the sprayer plate 22. The sprayer shading plate 21 is provided with through holes at positions corresponding to the sprayers 221 from which the sprayers 221 protrude respectively, protruding pillars 231 are disposed on and protrude from the sprayer base 23, and the protruding pillars 231 are each provided with a liquid flow channel that is in communication with the liquid spraying power supplying device 3.

In this embodiment, the colored lights 241 are preferably LED colored lights, and the sprayer base 23 is provided with through holes at positions corresponding to the colored lights 241 through which the light of the colored lights 241 passes. Thus, the light emitted from the colored lights 241 can pass through the sprayer base 23, the sprayer plate 22 and the sprayer shading plate 21 sequentially and upwardly propagate into the liquid columns sprayed. Then, changing light beams are formed by virtue of the refraction effect of the liquid columns to further present a dynamic and colorful dancing effect, which improves the ornamental value of the speaker remarkably.

In this embodiment, preferably, the liquid inlet is disposed at the central position of the liquid-delivery case cover 31 and the liquid outlet 311 is disposed near the outer edge of the liquid-delivery case cover 31. The end of each of the protruding pillars 231 extends into the liquid outlet 311 so that the liquid flow channel of each of the protruding pillars 231 is in communication with the liquid-delivery case 33. A magnet (not shown) is disposed within the impeller 32, and the driving device 5 drives, via a magnetic force, the impeller 32 to rotate so as to drive the liquid within the liquid-delivery case 33 to flow into the sprayer base 23 through the liquid outlet 311 and the liquid flow channel of each of the protruding pillars 231. A certain level of internal pressure is formed within the sprayer base 23 so that the liquid therein is sprayed upwardly through the sprayers 221 to form liquid columns that vary rhythmically, and meanwhile, the liquid columns are driven by the liquid column steering device 4 to rotate in the horizontal direction so as to generate the wiggly fountain spraying effect. Together with the changing light rays, a dynamic and colorful dancing effect is presented, and this remarkably improves the ornamental value of the speaker. The exhibiting cavity is an enclosed structure, so the liquid for forming the fountain will not be sprayed to the outside and the liquid loss is relatively small. Moreover, the liquid within the exhibiting cavity flows back to the liquid-delivery case 33 through the liquid inlet of the liquid-delivery case cover 31 under the action of gravity.
The liquid column steering device 4 comprises a link 43, and a driving gear 41 and a driven gear 42 that engage with each other, and stationary shafts are disposed at corresponding positions on an internal bottom surface of the bottom cover 12 to install the driving gear 41 and the driven gear 42 respectively. One end of the link 43 is pivoted to the driven gear 42 while the other end thereof is pivoted to the liquid-delivery case cover 31 so that a crank-link mechanism is formed. A magnet (not shown) is disposed within the driving gear 41, and the driving device 5 drives, via a magnetic force, the driving gear 41 to rotate so as to drive the liquid spraying power supplying device 3 to rotate. Thus, the liquid columns sprayed through the sprayers 221 are sloped to generate various dancing effects.
In a preferred embodiment, an eccentric first fixing pillar 421 is disposed on and protrudes from the driven gear 42, an eccentric second fixing pillar 312 is disposed on and protrudes from the liquid-delivery case cover 31, the two ends of the link 43 are provided with through holes for fitting with the first fixing pillar 421 and the second fixing pillar 312 respectively, and the two ends of the link 43 are nested onto the first fixing pillar 421 and the second fixing pillar 312 respectively via the through holes thereon.

In operation of the water dancing speaker of the present disclosure, the motor 53 rotates at a specific rotational speed (e.g., rotate rapidly, slowly or intermittently) according to the rhythm of the played track, and the motor 53 drives the driving pulley 52 and the driven pulley 54 to rotate. Both the driving pulley 52 and the corresponding impeller 32 are installed with a magnet, so the driving pulley 52 can drive the impeller 32 to rotate via a magnetic force. The high-speed rotation of the impeller 32 can apply a mechanical driving force to the liquid in the liquid-delivery case 33 so that the liquid in the liquid-delivery case 33 flows into the sprayer base 23 through the liquid outlet 311 and the liquid flow channel of the protruding pillar 231 and then is sprayed to the outside through the sprayers 221. When the liquid columns in the vertical direction are formed, the driven pulley 54 can drive, via a magnetic force, the driving gear 41 to rotate because both the driven pulley 54 and the corresponding driving gear 41 are installed with a magnet, and then the liquid spraying power supplying device 3 and the liquid spraying device 2 are driven to rotate so that the liquid columns sprayed through the sprayers 221 are sloped. As can be known from this, the water dancing speaker of the present disclosure can achieve the liquid spraying function and the liquid columns dancing effect simply through a motor 53, so the mechanical structure thereof is simple and useful and the cost is low.
The audio device 7 comprises a loudspeaker 71, a circuit board 72 and a Bluetooth module (not shown), and the circuit board 72 is electrically connected to the loudspeaker 71, the Bluetooth module, the colored lighting plate 24 and the motor 53.
