The present invention relates to an acoustic device, and more particularly, to an acoustic device having a simultaneous setting function and a sound system having a simultaneous setting function which can be applied to an acoustic device requiring at least one setting.

Modern band music generally includes vocals, first guitars, second guitars, bass guitars, keyboards, and drums. In the above configuration, the playing color of the guitar player plays a leading role in the overall atmosphere of the band music.

That is, even when playing the same music, the color of the entire band music depends on factors such as the playing style of the guitar player, the acoustic device, the guitar, and the like. In addition, among these, the type of sound device used by the guitar player and the setting values of the sound devices such as gain, level, tone, etc., have a high weight on the tone of the guitar player.

Accordingly, the guitar player memorizes all the settings for the plurality of sound apparatuses that he uses according to his or her original playing color, and according to the settings corresponding to the performance music every time the music is played, the plurality of sound apparatuses Set. After the performance of one song is finished, the plurality of sound devices are set again according to a setting value corresponding to the next song to be played.

An example of an acoustic device commonly used by guitar players is the Effector. Effector is a device that provides a variety of sound effects by changing the frequency waveform of the sound signal can be divided into analog effector and digital effector.

Analog-type effectors are commonly referred to as compact pedals, and each can be used as a compressor, distortion, chorus, delay, wah-wha and reverb effector. Effectors provide separate sound effects. In addition, the above independent analog effectors are used in connection with each other for the original tone pursued by guitar players.

The digital type effector may include a multi-effector or a rack type effector, for example, and combines the functions of the independent analog effectors.

The analog effector as described above has the disadvantage that the sound quality is high, the price is high, and various setting values cannot be stored, and the player must manually set the effector when playing. In addition, the digital effector can store various setting values and control various settings at the same time, but the sound quality is lower than that of the analog sound device, and the digital effector with excellent sound quality is very expensive. .

Nevertheless, semi-professional players who are more concerned with sound quality prefer high-quality analog sound effects with higher prices.

1 is a block diagram showing an example of connection and use of a general sound device.

Referring to FIG. 1, in the configuration of a general guitar player acoustic device, an electric guitar 10 and a plurality of effectors 21 to 23 are connected in series so that each of the effectors 21 to 23 is output from the electric guitar 10. By changing the sound signal so that a variety of sound effects added sound signal is output. The last effector 23 and the amplifier 30 of the plurality of effectors 21 to 23 connected in series are connected to amplify the sound signals sequentially processed from the plurality of effectors 21 to 23, and then the speaker 40. Output through

Here, the amplifier 30 may be used by separating a preamplifier and a power amplifier, or an integrated amplifier configured by the same block in which the preamplifier and the power amplifier are formed.

The plurality of effectors 21 to 23 are analog methods that provide different sound effects such as compressor, distortion, chorus, delay, wow wow, reverb, overdrive, phaser, and flanger effect. It can be any of the effects (eg, compact pedal type effects).

Each of the effectors 21 to 23 includes at least one analog variable resistor (or analog potentiometer) (not shown) capable of adjusting the processing level of the sound effect provided by each effector. Examples of analog variable resistors included in each of the effectors 21 to 23 may include gain, level, tone, volume, feedback, and the like.

Referring to Fig. 1, an example of use of a conventional acoustic system will be described. First, the guitar player 50 starts with each of the effectors 21 to 23 and the amplifiers (3) to obtain a sound effect suitable for the first song before playing the first song. An analog variable resistor provided in 30 is manipulated to set the respective effectors 21 to 23 and the amplifier 30.

After the performance of the first song is finished, the guitar player 50 performs the settings for each of the effectors 21 to 23 and the amplifier 30 in the same manner as above to obtain a sound effect suitable for the second song. Play the song.

For example, if the effector used for the sound effect is tropical and each effector is equipped with three analog potentiometers, the guitar player will have to manually set 30 analog potentiometers for each song for the proper sound effect for each song. In addition, there is a disadvantage in that it is necessary to accurately store the setting values of the different variable resistors for each performance song in a real time performance.

In addition, when the effector is frequently used as in the above example, the setup time of the sound device becomes very long because the guitar player must manually operate the analog variable resistor provided in each effector before playing a predetermined song. There are disadvantages.

In order to overcome the above disadvantages, the sound device combines the convenience of digital devices such as storing and simultaneously setting various setting values while maintaining the quality of the analog sound device for a plurality of sound devices used by band music or players in various fields. It is desperately required.

Accordingly, it is an object of the present invention to provide an acoustic apparatus having a simultaneous setting function that can easily set the acoustic apparatus.
