Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic musical instrument, and more particularly to an electronic musical instrument that plays a scratch that is indispensable to disco music.
[0002]
[Prior art]
In general, an operator called a DJ in a record or a disco dancing with live music puts his hand on a record board placed on a rotating turntable and forcibly changes the rotation speed of the record board to reproduce special sound, It is known to use a technique called scratch to produce disco music.
[0003]
[Problems to be solved by the invention]
However, in order to perform the above-mentioned scratching, a DJ mixing console equipped with a record player is required, and since the DJ mixing console cannot be moved easily because the record player is a stationary type, the use place is limited. I couldn't easily scratch and produce disco music anywhere.
[0004]
SUMMARY OF THE INVENTION It is an object of the present invention to provide an electronic musical instrument which solves the above-mentioned problems and can play a scratch which produces a disco while moving anywhere without restriction on the place where the performance is performed.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, an electronic musical instrument according to the present invention has the following requirements.
(B) A disk-type operation panel for performing a scratch operation is arranged on the upper surface of the instrument body. (B) A digital audio signal which is provided with a circuit for storing a digital audio signal in a memory circuit in the main body of the musical instrument, a circuit for scratching the stored signal, and a function for changing a reproduction speed. A signal reproducing device 4 and a monitoring amplifier 6 for an operator to monitor reproduced sound by headphones are provided.
(C) An operation section is connected to the musical instrument main body, and the operation section is provided with control means for controlling an output of the digital audio signal reproducing device.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0007]
FIG. 1 shows an electronic musical instrument. This electronic musical instrument is formed by imitating an electric guitar, and includes an instrument main body 1 and an operation section 2 connected to the musical instrument main body 1.
[0008]
The musical instrument main body 1 is made of a synthetic resin such as wood or plastic, and is formed in a hollow shape simulating the body of an electric guitar. A support device 9 for rotatably supporting the disc-type operation panel, and a circuit for temporarily storing the digital audio signal in a memory circuit and performing a scratch operation on the stored signal, wherein the playback speed is changed. A digital audio signal reproducing device 4 of a type called silicon audio and a monitoring amplifier 6 for an operator to monitor reproduced sound by headphones are arranged. A digital audio signal recording medium 20 such as a smart media, a memory stick, an SD memory card, or an MD is inserted into a socket and supplies a digital audio signal to the digital audio signal reproducing device 4. A fader volume 7 and a push button switch 8 are externally connected to the output of the digital audio signal reproducing device 4, and a jack 11 for outputting an output signal to the mixer 10 and a power supply 12 are connected. Further, a jack 13 for outputting to a headphone 19 for monitoring by an operator is connected to the monitoring amplifier 6 (see FIG. 2).
[0009]
The operation unit 2 is formed to imitate the neck of an electric guitar, and a control unit A is disposed substantially at the center. The control means A comprises a slide-type fader volume 7 with a switch and a push button switch 8. The fader volume 7 adjusts the level of an output signal output from the main amplifier 5 to the audio mixer 10 and turns on the output. / OFF can be selected, and the push button switch 8 is provided so as to output at a predetermined volume when pressed, regardless of the volume of the fader volume 7.
[0010]
A usage mode of the electronic musical instrument configured as described above will be described. The operator inserts the digital audio signal recording medium 20 into the socket 5, inserts the plug 15 at one end of the output cable 14 into the jack 11, connects the plug 16 at the other end to the mixer 10, and connects the plug 17 of the headphones 19. The power of the mixer and the electronic musical instrument is turned on by inserting it into the jack 13.
[0011]
Next, as shown in FIG. 3, the electronic musical instrument is held in a horizontal state with the strap 18 over the shoulder, and a finger is attached to the circular operation panel 3 imitating the turntable portion of the record player, at an arbitrary speed and at an arbitrary speed. The scratch can be played by rotating or rotating in the rotation direction. When the operation panel is stopped, the sound is reproduced at a speed corresponding to the rotation speed when the operation panel is stopped, and the reproduction is performed reversely at a speed corresponding to the rotation speed when the rotation is manual left. The operator adjusts the fader volume 15 while listening to the sound reproduced by the monitoring headphones 19 and outputs the reproduced sound to the audio mixer 10. In addition, the push button switch 8 can output a preset loud reproduction sound only when pressed, while the change in volume by the fader volume 7 is smooth. By using the fader volume 7 and the push button switch 8 properly, a powerful performance can be performed.
[0012]
As described above, scratching can be performed as if playing an electric guitar, and disco music can be produced with a simple device. Although a guitar type is taken as an example, the shape is not limited, such as a flat type.
[0013]
【The invention's effect】
According to the first aspect of the present invention, it is easy to carry and the use place is not limited, and the player can perform a scratch performance in which a disco is produced while moving at an arbitrary place without using a record board.
[0014]
According to the second aspect of the present invention, by using a digital audio signal reproducing apparatus called silicon audio, a scratch performance can be performed while moving the body by utilizing a feature that reproduction can be stably continued against the vibration. It can produce exciting performances or disco music. In addition, since the operation can be performed even when the electronic musical instrument cannot be held in a horizontal state, it is possible to visually produce more exciting performance or disco music.
