Sound output effect device and control method of nurturing chorus supported karaoke system

The present invention relates to a sound output effect device and a control method of the foster chorus support karaoke system, in particular, having a plurality of speakers in the side space of the karaoke, switching the music input to each channel according to the user's selection and electronic volume The present invention relates to a sound output effect apparatus and a control method of a vocal chorus system for supporting chorus, which can diversify the sound output effect by controlling it individually.

Generally, a karaoke system in which a fostering chorus is provided is largely divided into a music player that outputs existing performance music and a chorus player that supports a fostered chorus that is stored in correspondence with the performance sound output from the music player. Here, the chorus player uses a system to digitally record and play back using a storage device such as a CD or a separate hard disk, and in particular, to process a large amount of growing chorus data, MPEG Audio Layer 2 Is recorded.

That is, the general fostering chorus support karaoke system as shown in FIG. 1 includes a key input unit 50 including a plurality of keys for selecting a number corresponding to a music performance or setting a pitch, a speed, and the like. Main system controller 52 for controlling the overall function of the karaoke system in accordance with the signal input through the input unit 50, and music player for outputting the stored music data in accordance with the control signal output from the main system controller 52 And a chorus playing section 56 for demodulating and outputting the fostered chorus signal compressed and stored in accordance with the control signal output from the main system controller 52 into an original signal, and the chorus playing section 56 and the music playing. Mixer unit 58 for mixing the fostering chorus signal and the music performance signal output from the unit 54 and the music playing and fostering choruses mixed through the mixer unit 58 in stereo. It consists of the 1st and 2nd speakers 60 and 61 which output negatively.

On the other hand, look at the operation of the karaoke system supporting the Ukseong chorus composed of such a configuration as follows.

First, when a user inputs a number or sets a pitch and speed mode key by combining a plurality of keys of the key input unit 50, a signal corresponding thereto is input to the main system controller 52. The main system controller 52 then outputs the corresponding music performance stored in the music player 54 as the control signal. Therefore, the music performance stored in this music player 54 is output through the speaker 58 via the mixer 58. In this case, when the music performance set by the user is a song supporting the fostering chorus, the main system controller 52 controls the signal corresponding to the fostering chorus stored and compressed in the chorus player 56 as the control signal at a predetermined time. 58).

Accordingly, the mixer unit 58 outputs the music performance and the growth chorus through the first speaker 60 and the second speaker 61 after the mixing process according to the set signal, so that the user is supported not only the music performance but also the growth chorus. Allow them to sing.

On the other hand, in such a karaoke system, a plurality of function buttons are installed in the key input unit 50 so as to make the sound input through the speaker or the sound output by the listener more vivid. For example, the first speaker 61 and There is a function for giving a specific echo and reverberation to the audio signal output to the second speaker 62.

Depending on the type of music, however, the classical chorus-supported karaoke would have the effect of being in a concert hall for classical music, the effect of being in a live venue for rock music, and the effect of being in a discotheque for dance music. In the system, the playing sound or chorus sound is output by arranging the pattern or echo of each playing instrument sound by arranging it. . In other words, the speaker installed in a karaoke of a certain space is usually installed in the front of about two, the sound output through this speaker was difficult to expect the dramatic effect of the karaoke space only by stereo sound or reverberation effect, etc. .

Accordingly, the present invention has been made to solve the above-mentioned problems, the music data is arranged in a predetermined space in which a karaoke system is installed with a plurality of speakers at a predetermined interval and arranged by each channel in the sound source built-in each It is an object of the present invention to provide a sound output effect device and a control method of the fostering chorus-supporting karaoke system that can express various music output effects by sequentially switching operation by a multiplexer and individually controlling by electronic volume.

In order to achieve the above object, the present invention provides a main system controller for controlling an overall karaoke system corresponding to a song selection number, speed, and pitch inputted through a key input unit, and music stored according to a control signal of the main system controller. A music player for signal processing and outputting a performance, a chorus player for signal processing and outputting a growing chorus in a compressed and stored CD according to a control signal of the main system controller, and a chorus output from the chorus player and music player It consists of a multiplexer that sequentially outputs music data corresponding to sound and music to each channel by separating and switching, and an electronic volume that individually controls music signals of each channel output from the multiplexer and outputs them to each speaker.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The karaoke system supporting the fostering chorus to which the present invention is applied includes a key input unit 1 for setting a song selection number and a sound output effect mode through a plurality of specific keys as shown in FIG. 2, and the key input unit 1. The main system control unit 2 which controls the overall karaoke system according to the signal input through the control unit, and the music playing unit 3 which processes and outputs the stored music performance data according to the control signal of the main system control unit 2. And a chorus playing portion 4 for processing and outputting the growing chorus data in the compressed and stored CD according to the control signal of the main system controller 2, the chorus playing portion 4 and the music playing portion 3; Multiplexed to sequentially output the music data corresponding to the music performance and chorus sound output from the channel by separating and switching to each channel according to the control signal of the main system control unit (2) It comprises a unit 5, a multiplexer 5, the electronic volume (6) by controlling the music signals of the respective channels individually for outputting the music played by the sound effect output from the state.

Four speaker stages (SP) are connected to the rear end of the electronic volume (6), where the first speaker (8) and the second speaker (9) are installed on both sides of the front of the karaoke space, and also the third speaker (10). ) And the fourth speaker 11 are installed at both rear sides of the karaoke space to face the front speakers (8, 9).

On the other hand, look at the operation of the present invention made of such a configuration as follows.

First, when the user sets the music selection of the song number and its pitch through the key input unit 1, this signal is input to the main system control unit 2. Then, the predetermined control signal outputted from the main system control unit 2 is input to the music player 3 and the chorus player 4 so that music playing starts according to the set pitch, and the chorus that is raised at the corresponding time during the music play. Is also played. That is, the music player 3 and the chorus player 4 output the stored performance music data and chorus data according to the control signal of the main system controller 2 and the signals are multiplexed through the multiplexer 5. It is separated into the channel of and is input to the electron volume 6. Therefore, the electronic volume 6 adjusts the audio signal input to each channel to a constant level, and accordingly the audio is input to each speaker stage SP, so that the first speaker 8 and the second speaker 9 ), The third speaker 10 and the fourth speaker 11 outputs the music performance and chorus sound of an audible frequency band of a predetermined level.

On the other hand, if the user located in the karaoke space to set the output sound effect mode through the key input unit (1) to increase the sound listening effect of the music is output to each speaker stage (SP) in accordance with the setting of the corresponding mode is continuous By setting the rotation effect mode to give the effect of rotating around the listener to the resulting signal is input to the main system control unit (2). Then, the music performance data and the chorus performance data input to the multiplexer 5 according to the control signal of the main system controller 2 are separated into multiple channels, and the audio signal according to the switching operation of each channel is transferred to the electronic volume 6. Is entered. Therefore, in the electronic volume 6, the audio signals sequentially input from the respective channels are output to the outside through the respective speakers 8, 9, 10, and 11.

At this time, the music playing sound and the chorus playing sound output through each of the speakers 8, 9, 10, and 11 rotate the space attached to each side of the karaoke space as shown in FIG. For example, when a user listens to a performance sound output at an appropriate position of a karaoke room and sings a song, the sound output from the first speaker 8 gradually loses a sense of listening spatially, and the far away sound has a spatial sense of listening. Move to the second speaker (9). Then, the predetermined sound moved to the second speaker 9 is spatially separated again and moves to the fourth speaker 11, and the audio sound moved to the fourth speaker 11 also receives the third speaker ( 10, the user's listening space gradually moves to the first speaker 8. That is, the sound output from each of the speakers 8, 9, 10, and 11 installed at a predetermined distance in the karaoke interior space continuously from the first speaker 8 to the second speaker 9 centered on the listener. Hearing as it spatially rotates from the second speaker 9 to the fourth speaker 11, the fourth speaker 11 to the third speaker 10 and back from the third speaker 10 to the first speaker 8 The speaker can perceive the spatial three-dimensionality of the sound by recognizing that the speaker rotates around the listener and outputs the playing sound and the chorus sound.

On the other hand, when the user sets the cross effect mode through the key input unit 1, as shown in FIG. 4, negative spatial movement occurs in various forms. 4A illustrates a negative spatial shift when the left and right sound crossover mode is set by the user's key selection. That is, when the listener is located in the appropriate space (P) of the karaoke, the sound output from the first speaker 8 is moved to the second speaker (9) around the listener with a time difference and the third speaker (10). Play music output from the) is moved to the fourth speaker 11 around the listener with a time difference. Therefore, the listener perceives the spatial stereoscopic feeling by feeling that the speaker outputting the performance sound moves from left to right. The sound may be selected to be moved from left to right or right to left according to a user's key input.

4B shows a negative spatial movement when the front and rear crossover mode is set by the user's key selection. That is, when the listener is located in the appropriate space (P) of the karaoke, the sound output from the first speaker 8 is moved to the third speaker 10 around the listener with a time difference and the second speaker 9 Playing music output from the) is moved to the fourth speaker 11 around the listener with a time difference. Therefore, the listener perceives the spatial stereoscopic feeling by feeling that the speaker outputting the performance sound moves from the front side to the rear side. Here, according to the user's key input, the sound may be selected to be moved from the front side to the rear side or from the rear side to the front side.

In addition, shown in FIG. 4C shows a negative spatial movement when the diagonal tone crossing mode is set by the user's key selection. That is, when the listener is located in the appropriate space P of karaoke, the sound output from the first speaker 8 is moved to the fourth speaker 11 around the listener with a time difference, and the second speaker 9 Playing music output from the) is moved to the third speaker 10 around the listener with a time difference. Therefore, the listener perceives the spatial stereoscopic feeling by feeling that the speaker which outputs the performance sound moves diagonally from the front side.

On the other hand, as shown in Figure 3b by dividing a certain karaoke space equipped with a karaoke system supporting chorus sound into nine patterns and by inputting a number corresponding to the position of the listener can adjust the volume of the sound felt by the listener. For example, when the listener is at a position corresponding to the pattern number 1 on the karaoke space, the pattern number 1 is selected through the key input unit 1. Then, the sound level of the music performance output from the first speaker 8 is lower than the sound level output from the fourth speaker 11. In addition, the level of the sound output from the third speaker 10 and the second speaker 9 is greater than the volume of the sound output from the first speaker 8 and lower than the audio volume output from the fourth speaker 11. Is set. That is, by selecting the position of the listener according to the nine patterns in this way, the sound volume of the speaker installed at each position in the karaoke is adjusted appropriately. On the other hand, if the listener does not set the mode, the listener is automatically set to the position in pattern number 5.

In addition, although the performance music output through each speaker is output independently of each other, the performance sound can be output only from the first speaker 8 and the second speaker 9 installed at the front according to the selection mode of the listener. Performance sound can be output only from the speaker 10 and the fourth speaker 11.

On the other hand, look at the control method according to the present invention for outputting the performance sound having a variety of effects in accordance with the selection of the listener as follows.

That is, as shown in FIG. 5, the initial state S1 in which power is supplied to the karaoke system to perform a normal operation proceeds to the song selection step S2. Then, in this song selection input step (S2) to set the corresponding number, speed and pitch to output the performance sound, and proceeds to the performance sound output step (S3). Accordingly, in the performance sound output step S3, the corresponding performance music is output at the set pitch and speed according to the input information, and the output sound effect mode setting determination step S4 is performed. Therefore, when it is determined in the output sound effect mode setting determining step S4 that the mode for adding an effect to the output sound is set, the process proceeds to the sound revolving mode determining step S5. At this time, if it is determined that the playing sound rotation effect mode is set as the result determined in the playing sound rotation mode determination step (S5), the flow proceeds to the forward rotation mode determination step (S6). Therefore, when it is determined in the forward rotation mode determination step (S6) that the forward rotation direction mode of the performance sound is set, the flow proceeds to the forward rotation effect sound output step (S7) and the speaker installed in the karaoke space is spatially moved in the clockwise direction to play. This loop ends with a sound output. If it is determined in the forward rotation mode determination step (S6) that the forward rotation direction mode of the performance sound is not set, the process proceeds to the reverse rotation effect sound output step (S8) and the speaker installed in the karaoke space is spatially counterclockwise. Move to output your performance and end this loop.

On the other hand, if it is determined that the playing sound rotation effect mode is not set as determined in the playing sound rotation mode determination step (S5) proceeds to the playing sound cross-mode determination step (S9). Then, when it is determined that the mode for the cross effect of the performance sound is set as determined in the performance sound cross-mode determination step (S9), the process proceeds to the front and rear cross-mode determination step (S10). Therefore, as a result of judging in the front and rear cross mode determination step (S10), if it is determined that the playing sound output from the speaker in front of the space of the karaoke is in a cross mode with the playing sound output from the rear speaker, then the step back and forth crossing sound output step (S11) Proceed, output the performance sound with the crossed effect before and after, and end this loop.

When it is determined in the cross-back mode determination step (S10) that it is determined that the cross-back mode is not set, the flow proceeds to the cross-right mode determination step (S12). Therefore, when it is judged in this left and right cross mode determination step (S12) that the mode in which the playing sound output from the speaker installed on the left and right is set centered on the front listener, the process proceeds to the left and right cross play sound output step (S13). End the loop by outputting the sound with the left and right crossings around the ruler. In addition, when it is determined in the left and right cross mode determination step (S12) that the left and right cross sound mode is not set, the process proceeds to the diagonal cross sound output step (S14), and outputs the sound to cross in the diagonal direction centering on the listener. End the loop.

On the other hand, if it is determined that the playing sound cross mode is not set as determined in the playing sound cross mode determining step (S9), the process proceeds to the listening position setting determining step (S15). Therefore, when it is determined in the listening position setting determining step (S15) that the mode according to the listening position is set, the procedure goes to the listening position selecting step (S16). Therefore, in this listening position selection step S16, the proper position is set by the listener, and the process proceeds to the optimum level adjustment performance sound output step S17. Therefore, in this optimum level adjustment performance sound output step S17, the level of the performance sound output from each speaker is adjusted and output appropriately at the position of the listener, and this loop ends.

If it is determined in the listening position setting determination step (S15) that the mode according to the listening position is not set, the process proceeds to the output selection mode determination step (S18). Then, if it is determined in the output selection mode determination step (S18) that it is determined that the output speaker selection mode, the process proceeds to the output speaker setting step (S19). Therefore, in this output speaker setting step (S19) to set the speaker to be output and proceeds to the performance sound output step (S20) to output the performance sound only in the set speaker and the end of this loop. If it is determined in the output selection mode determination step (S18) that the selection mode of the output speaker is not set, the process proceeds to the output sound effect mode setting determination step (S4) and satisfactorily performs this loop.

As described above, the present invention installs the speakers in front, rear, left and right centers of the listener in a karaoke having a predetermined space, and the playing sound output through the speaker, the sound playing mode rotation mode, playing sound cross mode, playing position setting mode and It is possible to improve the function of the karaoke system by setting the output selection mode according to the choice of the listener so that the listener can feel a more spatial three-dimensional feeling in the karaoke, which is the output space of the performance sound.
