Description:
BACKGROUND  
         [0001]    This invention relates generally to aquariums, and specifically, to a decorative aquarium with water dance effect, in which the intensity of the bubbles and colors of light are controlled by, and varied with, the melody of a music so as to achieve both visual and audio entertaining effect.  
           [0002]    A conventional decorative aquarium includes a case and a base seat for protecting the case. Partitioning boards are disposed in the case at a certain height to divide the case into multiple chambers. A pump, a thermostat, a filter, and a fish tank are placed in the chambers. A viewing board, which can be a mirror or a board material that is designed and modified by a user, is arranged above the partitioning boards. A bottom rack is disposed under the viewing board. Such conventional decorative aquarium can achieve a decorative effect. However, the case is shallow and narrow that fish may jump out of the case.  
           [0003]    Another conventional decorative aquarium, as may be disclosed by Wen-Yung Lin in his “Decorative Lamp in Aquarium Tank,” U.S. Pat. No. 5,993,021 (“&#39;021 patent”), illustrates an attempt to improve upon the aforementioned conventional decorative aquarium. Such decorative aquarium has a transparent tubular main body containing a liquid, an air pump being disposed on the bottom thereof, and fake fish that floats in the liquid. However, the fake fish can only move along a fixed path of the bubbles generated by the air pump, and such decorative aquarium does not appear realistic.  
           [0004]    Yet another conventional decorative aquarium illustrates an attempt to improve upon the aforementioned conventional decorative aquarium. In his “Submerged Luminaire” patent, Japanese Patent No. 8077807 (“JP &#39;807 patent”), Norihiro Shinya discusses a submerged luminaire having various lighting effects for lighting from inside a water tank and having stereoscopic effect. Such luminaire consists of a light source and an optical fiber light guide coupled at an incident end to the light source and an outgoing end is arranged in the water tank. The outgoing end is arranged in a line and is adjacent to an air diffuser having bubble generating holes and the outgoing end and the air diffuser are integrally formed by an integral member. An air compressor is connected to the air diffuser through an air pipe and compressed air is fed from the compressor. However, the lighting effect, at most, is coordinated with the generated air bubbles and not with any other effect, such as a melody of music.  
           [0005]    Yet another conventional decorative aquarium, as may be disclosed by Hitoshi Ando in his Japanese Patent No.10085460 (“JP &#39;460 patent”), entitled “Air Bubble Generator by Musical Sound,” illustrates another attempt to improve upon the aforementioned conventional decorative aquarium. Ando&#39;s air bubble generator is provided with a water tank housing a liquid and provided with multiple air bubble generation ports, an air bubble generation mechanism for generating air bubbles from multiple air bubble generation ports, and a control part for controlling the air bubble generation mechanism corresponding to musical sound information and controlling the generation of the air bubbles from the air bubble generation ports. The air bubbles are generated from the air bubble generation ports corresponding the musical sound information. However, Ando&#39;s air bubble generator lacks additional decorative effect such as lighting effect that is also coordinated with the musical sound information.  
           [0006]    Therefore, it is a primary object of the present invention to provide a decorative aquarium with water dance effect. The decorative aquarium can be switched into a sonic frequency-controlled mode in which the intensity of the bubbles and colors of light are controlled by, and varied with, the frequency of music.  
           [0007]    Further object of the present invention is to provide the above decorative aquarium by which a user can at the same time enjoy the music and watch the water dance for both visual and audio pleasures.  
         SUMMARY  
         [0008]    The present invention satisfies these needs.  
           [0009]    The decorative aquarium with water dance effect of the present invention comprises a transparent main body, a base seat, a controlling circuit, a single chip, an electrical air pump, and multiple light emitting sources. The transparent main body, detacheably engages the base seat for support. The single chip, the electrical pump, and the light emitting sources are connected to the controlling circuit, and they are disposed in the base seat. The amount of air and the rate of discharge of the air pumped out by the air pump, as well as the color of light emitted by the light emitting sources can be varied according to the music melody generated by the single chip to create the water dance effect.  
           [0010]    The controlling circuit may further include a controlling switch for activating the decorative aquarium into a water dance effect mode to produce such water dance effect. Therefore, a user can simultaneously enjoy the music and watch the water dance for both visual and audio pleasures.  
           [0011]    The controlling circuit may further include a controlling switch capable of switching the decorative aquarium into a common function mode to disable the water dance effect, in which case the size, and the discharge rate of air pumped out by the air pump, and the flickering color of light emitted by the light emitting sources remain constant.  
           [0012]    In another embodiment of the present invention, the main body further comprises a plurality of floating decorative articles located therein for further visual entertainment effect.  
           [0013]    In yet another embodiment of the present invention, the light emitting sources are vertically placed in the base seat.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0021]    Referring to FIGS. 1 and 2, the decorative aquarium of the present invention, the decorative aquarium of the present invention includes a transparent main body  10 , a base case  20  and a controlling circuit  30  installed in the base case  20 . The transparent main body  10  is preferably made out of a transparent tube with a certain length, and it is filled with a liquid. The bottom of the main body  10  engages a base seat  11 . Two locating blocks  13  are respectively formed on two opposite sides of the base seat  11 . Multiple light emitting sources  15  with different colors, such as red, blue and green, and an air pump  14  are disposed in the interior of the base seat  11 . The outlet of the air pump  14  via a communicating pipe  16  is connected to a through hole  12  of the bottom of the main body  1 .  
         [0022]    The top face of the base case  20  is formed with a receptacle  22  with a shape corresponding to that of the base seat  11  of the main body  10 . Two opposite sides of the receptacle  22  are formed with locating channels  23 , to which locating blocks  13  are engaged for stabilizing the main body  10  to the base seat  11 . Two speakers  21  are mounted on two sides of front face of the base case  20 . Two switches  26 ,  27 , a socket  24  and five function keys  25   a  through  25   e  are disposed under the speakers  21 . The switches, socket and function keys are electrically connected with the controlling circuit  30  in the base case  20 . A power wire  28  extends from the controlling circuit  30  out of the base case  20 .  
         [0023]    [0023]FIG. 3 is a circuit diagram of the controlling circuit  30 . The controlling circuit  30  includes multiple transistors, resistors, capacitors, and a single chip  31  having at least one random access memory, in which a controlling program is stored. The two switches  26  and  27  are respectively connected with the tenth and twenty-second pins of the single chip  31 . The five function keys  25   a  through  25   e  are respectively connected with the eleventh, twelfth, thirteenth, twentieth and twenty-first pins. The socket  24  is connected with the twenty-fifth pin to form the controlling circuit.  
         [0024]    After powered on, the present invention has two options: (1) a common function mode and (2) a water dance function mode.  
         [0025]    Option 1—Common function mode. The switch  26  is switched off to activate the common function mode. During the common function mode, the rate of discharge of the air bubbles from the air pump  14  is continuous and constant. The light emitting sources  15  are all switched on or off. By means of the switch  27 , a set of built-in music melodies that are stored in the random access memory of the single chip  31  can be selected for play. By means of the press key  25   a , a single built-in melody can be selected to be played. Alternatively, by means of the press key  25   b , multiple built-in melodies can be played in sequence. By means of the press keys  25   c  and  25   d , the volume of the music can be adjusted. By means of the press key  25   e , the music can be stopped while the bubbles are still continuously discharged.  
         [0026]    Option 2—Water dance function mode. The switch  26  is switched on to activate the water dance function mode. The rate of discharge of air bubbles from the air pump  14  and the operation of the light emitting sources  15  are entirely determined by the melody of the music. Therefore, when different melodies are selected via the switch  27 , press key  25   a , or press key  25   b , the air pump  14  and the light emitting sources  15  will be controlled accordingly to create a unique water dance pattern.  
         [0027]    In addition, fake water fowls  40  can be placed in the transparent main body  10  as shown in FIG. 4. The air pump  14  can pump bubbles into the main body for the fake water fowls  40  to float therein. In addition, as shown in FIG. 5, when the switch  26  is switched to water dance function mode, the fake water fowls  40  can freely and lively float in the liquid with patterns varied with the frequency of the music. Moreover, in cooperation with sound and light effect, a visual and audio entertaining effect can be achieved.  
         [0028]    As shown in FIG. 6, a user may choose to connect speakers  50  externally to the socket  24  to produce music with higher power output, in case speakers  21  that are built in the base case  20  does not produce adequate music power output for the user, and the user desires amplification of the music via use of powered speakers such as speakers  50 . For instance, the user may elect to connect the present invention to a set of elaborate audio system capable of producing surround sound effect to enjoy the music produced by the present invention with three-dimensional sound effect. Or, the user may choose to connect a subwoofer for better bass sound quality of the music produced by the present invention.  
         [0029]    In sum, according to the decorative aquarium of the present invention, the amount of the bubbles and the flickering light can be controlled by the melody of the music produced by the single chip  31 . Therefore, when enjoying the music, a user can watch the floating decorative articles including artificial water animals such as fake water fowls  40  and the colorful light varied with the melody at the same time, resulting in a novel decorative effect.  
         [0030]    The above embodiments are used only to illustrate the present invention, and it is not intended to limit the scope thereof. A person skilled in the art will readily recognize similar variations and alternative embodiments of the present invention, without departing from the spirit of the present invention.
