Control circuit assembly for fountain display apparatus

A control circuit assembly used in a fountain display apparatus, comprising:

• a built-in sound source circuit and an external sound source circuit adapted for providing a sound source, said built-in sound source circuit and said external sound source circuit being so arranged that said built-in sound source circuit is off when said external sound source circuit is on, said built-in sound source circuit comprising an IC having stored therein pieces of music, said external sound source being connectable to an external audio apparatus for input of music;
• a low-frequency amplification and output circuit, said low-frequency amplification and output circuit comprising an IC adapted for picking up and amplifying low frequency signal from the sound source provided by said built-in sound source circuit and an external sound source circuit, a variable resistor for volume control, and a transistor for controlling output of amplified low frequency signal;
• an audio amplification and output circuit, said audio amplification and output circuit comprising an IC adapted for amplifying sound signal provided by said built-in sound source circuit and an external sound source circuit, and speaker means for output of amplified sound signal;
• a LED driver, said LED driver comprising a plurality of LEDs (light emitting diodes), and a plurality of transistors and adapted for controlling said LEDs respectively;
• a motor driver, said motor driver comprising a triggering diode, and a plurality of motor pumps connected in parallel to said triggering diode and controlled by said triggering diode to pump waters in producing artificial springs;
• a timer circuit, said timer circuit comprising an IC adapted for receiving output signal from the low-frequency amplification and output circuit and controlling the transistors of said LED driver and the triggering diode of said motor driver to turn on/off said LEDs and said motor pumps subject to output signal from said low-frequency amplification and output circuit, a time control program set therein for controlling said LED driver and said motor driver to turn on/off said LEDs and said motor pumps subject to a predetermined setting.
