In order to achieve the above object, a fountain device according to the present invention comprises an acoustic device for playing music recorded in a music source such as a compact disc into sound waves, and a fountain. Database for fountain production that accumulates data of fountain operation for each production mode, and music data of the music recorded in the above music source is read in advance of the fountain production, and based on this music data and the data in the database And a drive system control unit for controlling the drive of the fountain drive system in accordance with the fountain operation determined by the arithmetic and control unit when the performance of the music is started. Is.

[0007]

According to the present invention, the music data of the music of the music source is taken into the arithmetic and control unit prior to the performance of the fountain, and the fountain operation for the played music is performed based on the data in the database. Since it is decided, it is not necessary to prepare a database for each song, you can get a fountain form that suits this for any song, and by incorporating the above music data in advance of production,
It is possible to obtain an accurate fountain form that matches the characteristics such as the musical tone of a musical piece by synchronizing it with the musical piece, and it is easy to produce a complex fountain.

Reference numeral 8 denotes an acoustic device for converting the electric signal reproduced from the music of the music source 6 into a sound wave and playing the sound.
It includes an amplifier 9 and a speaker 10.

Reference numeral 11 denotes a separately prepared database for fountain production, in which data of fountain operation for each fountain production form is accumulated. Reference numeral 12 denotes a personal computer (hereinafter, referred to as a personal computer) as an arithmetic control device for taking in music data such as volume and pitch from the reproduction output of the music of the music source 6 prior to the fountain production by the fountain nozzle 2. It has a function of determining the fountain operation for the music based on the data in the database 11 when the music data is taken in.

A control unit 13 is controlled by an output from the personal computer 12, and is a first controller 13A for controlling the rotation of the pump 1 via the motor 4.
And a second controller 13B that controls the opening and closing of each of the solenoid valves 3 described above.
