Abstract

The present invention relates to a three-dimensional sound output sound control device that can output a more improved three-dimensional sound by adjusting the output sound of the three-dimensional sound.

Stereo sound, also known as stereo sound, allows you to listen to the left and right sounds simultaneously by mixing the separate recordings during recording and separating them during playback. Therefore, the conventional stereoscopic sound output device has a problem that can not see the proper reproduction effect because there is a sound that does not hear well when many kinds of sounds such as orchestra is mixed.

The present invention is a three-dimensional sound reproducing apparatus, the sound input unit for receiving the left and right sound signals, respectively, the left and right pretone controller for adjusting the pretone of the left and right sound signal, and the sound signal output from the pretone controller on the right or left A sound output control device capable of delaying and adjusting the volume, and a stereo sound output sound control device including left and right main pretone controllers, left and right main amplifiers and left and right output units are provided.

Description

Sound controller for streo sound {Sound controller for streo sound}

The present invention relates to a three-dimensional sound reproducing apparatus, and more particularly to a three-dimensional sound output sound control device that can output a more improved stereo sound by adjusting the output sound of the stereo sound equipment.

In the conventional stereo sound recording, the left and right sounds are separately inputted at the time of recording, and the left and right sounds mixed in the playback apparatus are separated to be output through each output unit so that the listener can listen to the three-dimensional sound.

Dolby systems are also known as a more advanced method of stereoacoustics. Dolby Surround sound system is a system that can listen to the sound more three-dimensional by varying the output speed of the same sound by delaying the output speed of the output sound of the left and right surround speakers than the output sound of the main left and right speakers.

In recent years, however, portable sound reproducing apparatuses such as cassette players have become commonplace, and digital sound reproducing apparatuses capable of reproducing fine sounds such as MP3 players and the like have been widely used to listen to them using a headset or earphone.

Therefore, there is a need for the development of a device capable of producing the same sound as the Dolby system even through the earphone or headphone. This invention is devised in view of such a point.

However, the prior art is effective in that the left and right surround output devices having different installation positions in addition to the main left and right sound output devices may have an effect, so the effects can be seen in the left and right main output devices, for example, an output device using earphones. There is no problem.

The present invention is to solve the problems of the prior art, an object of the present invention is to improve the stereoscopic output of the output by adjusting the speed and volume of the left or right output sound in the stereo sound output device, which is not reproduced It is to provide a stereo sound output sound control device for outputting sound.

As a technical idea for achieving the object of the present invention, a sound input unit for receiving the left and right sound signals respectively, a left and right pretone controller for adjusting the pretones of the left and right sound signals, and the right or left output from the pretone controller A sound output adjusting device capable of delaying and adjusting a sound signal, and a stereo sound output sound adjusting device including left and right main pretone controllers, left and right main amplifiers, and left and right output units are provided.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the embodiment of the present invention.

1 is a schematic block diagram of an embodiment of the present invention.

As shown in FIG. 1, the left sound input unit 10 and the right sound input unit 20 are input by separating stereo stereo sound into left and right sound signals;

Left and right pretone controllers 11 and 21 connected to the left and right sound input units 10 and 20, respectively,

A sound output adjusting device 12 connected to either output terminal of the left or right pretone controller 11 or 21,

Main preton controllers 13 and 22 connected to the output sound adjusting device 12 and the left or right pretone controllers 11 or 21, respectively;

Left and right amplifiers 14 and 23 connected to the left and right main preton controllers 13 and 22, respectively;

It consists of a left and right sound output section connected to the left and right amplifiers 14 and 23, respectively.

The left and right pretone controllers 11 and 21 are devices included in the preamplifier, and include a mode and a frequency characteristic for changing the signal flow in the speaker or the listening room.

The main pretone controllers 13 and 22 are devices included in the main amplifier.

The output sound adjusting device 12 is a core configuration of the present invention, which is shown in detail in FIG.

Referring to FIG. 2, the output sound adjusting device 12 connected to an output terminal on either side of the left or right pretone controller 11 or 21 includes a switching unit 100 receiving an acoustic signal from the output terminal. And a signal delay unit 110 connected to the switching unit 100, a delay time adjusting unit 120 for adjusting a signal delay time of the signal delay unit 110, and the signal delay unit 110. It is configured to include a treble adjustment unit 130, a mid-tone control unit 140, a bass control unit 150 to be connected with.
