Thereby outputting an on / off switching signal.

Hereinafter, an operation process of the echo and stereo sound support apparatus configured as described above will be described.

When an unspecified number of users want to view or listen to a moving picture or music stored in a storage medium (for example, CD, DVD, etc.), the user in the storage medium driving means 10 as shown in FIG. When the video data and the sound data stored in advance are output by the key operation, the display means 20 receives the video data output from the storage medium driving means 10 and displays the video for the user to view.

Subsequently, the sound output means 30, for example, four-channel headphones or a speaker, receives the sound data output from the storage medium driving means 10 so that the user can hear the sound corresponding to the image and outputs the sound data to the user.

In this case, the user adds an echo function or provides stereo sound through the storage medium driving means 10 (for example, computer, audio, video, etc.), and the user directly operates the storage medium driving means 10 as described above. A device for supporting echo and stereo sound is mounted between the storage medium driving means 10 and the sound output means 30 without an operation so as to correspond to the image or sound data input from the storage medium driving means 10. The user can easily select the echo and stereo sound.

That is, the echo and stereo sound support apparatus receives and transmits sound data output from the storage medium driving means 10 from the first and second jacks 100 and 200, and the first and second volume control units ( 300 and 400 are coupled to the first and second jacks 100 and 200 to adjust the volume level of the sound data by a user's manipulation.

Then, the first amplifier 500 receives the sound data transmitted through the first volume control unit 300 and amplifies to a predetermined size to output an amplified signal, the third jack 600, the third 1 receives the amplified signal output from the amplifier 500, and outputs to the sound output means 30 so that the user can hear a three-dimensional sound.

In this case, the first amplifier 500 provides a stereo sound to the user through the sound output means 30 (for example, headphones, speakers, etc.) to a commonly used amplifier (Amp). If the sound output means 30 is described as an example of headphones, the function of the headphones uses two channels, four channels and virtual 5.1 channels.

That is, in the case of two-channel headphones, only the stereo sound is provided so that a user can simply listen to the acoustic data output from the first amplifier 500.

Meanwhile, when the second and fourth amplifiers 700 and 900 receive the sound data transmitted through the second volume controller 400 and amplify the sound data to a preset size, the second and fourth amplifiers 700 and 900 output the amplified signals. The amplifiers 800 and 1000 receive the amplified signals output from the second and fourth amplifiers 700 and 900 and amplify and output the amplified signals.

Then, the first and second repetition delayers 1100 and 1300 receive the amplified signals output from the third and fifth amplifying units 800 and 1000, repeatedly repeat the delay for a predetermined time, and then output an echo signal. The first and second switching units 1200 and 1400 receive the echo signals output from the first and second repetition delay units 1100 and 1300 and transmit the received echo signals to the third and fifth amplifiers 800 and 1000.

For example, when watching entertainment or movies, the user can provide a more enhanced three-dimensional effect, and when the echo function is not supported, the user can listen to normal music.

In addition, as mentioned above, when a user watches entertainment or a movie using the echo function through four-channel headphones, the movement or wind noise of the person is provided in the entertainment or movie content in various directions. The user can sense the direction of the position where the movement or the wind sound occurs through the four-channel headphones.

Meanwhile, as mentioned above, the microcomputer 1700 transmits through the first and second jacks 100 and 200 to automatically turn on / off the first and second switching units 1200 and 1400. After receiving the sound data, the video data is analyzed and the corresponding control signal is output.

Automatic on / off switching to the microcomputer 1700 by a user operating the auto mode switching unit 1800 so that the microcomputer 1700 automatically turns on / off the first and second switching units 1200 and 1400. Output the signal.

Meanwhile, when the echo and stereo sound support method is described in more detail as shown in FIG. 2, it is determined whether the automatic mode switching unit 1800 is turned on by the user's key manipulation in the microcomputer 1700 (S100). ).

In this case, the automatic mode switching unit 1800 is terminated when the automatic mode switching unit 1800 is not turned on in step S100, and when the automatic mode switching unit 1800 is turned on, the microcomputer 1700 is provided from the first and second jacks 100 and 200. It is determined whether sound data has been input (S200).

Subsequently, if sound data is not input in the sound data input determination step (S200), the process ends. When the sound data is input, the microcomputer 1700 determines whether video data is included (S300).

In addition, if the video data is included in the determining whether the video data is included (S300), the microcomputer 1700 outputs a control signal corresponding thereto (S400), and the first and second switching units 1200 and 1400. ) Receives the control signal output from the microcomputer 1700 is automatically turned on (S500) to support the echo function.

Meanwhile, if the video data is not included in the determining whether the video data is included (S300), the microcomputer 1700 outputs a control signal corresponding thereto (S310), and the first and second switching units 1200, In 1400, the control signal output from the microcomputer 1700 is automatically turned off (S320) to support stereo sound so that a user can enjoy normal music.
