DESCRIPTION JPH03274096
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
karaoke performance apparatus capable of producing an atmosphere as if it were playing in a
hall or the like, when singing a song with a microphone along with the reproduction of a karaoke
accompaniment music. [Prior Art] In a conventional karaoke performance apparatus, in order to
enhance the atmosphere during karaoke performance, some reverberation is added to the
singing voice signal of the microphone input and then mixing with accompaniment music is
performed, and the synthesized signal is used as a speaker The method of playing from the
beginning is taken. FIG. 4 is a block diagram showing the prior art example, and a music source
signal from an equipment group 1 for reproducing accompaniment music recorded on a compact
disc, video disc, cassette tape, etc. is transmitted via an amplifier 2. The level is adjusted
appropriately by the variable resistance attenuator 3 and is added to the mixing amplifier 4. On
the other hand, a singing voice singing along with the karaoke accompaniment sound is collected
by the microphone 5 to be an audio signal, branched through the amplifier 6 and the variable
resistance attenuator 7, and one is applied to the mixing amplifier 4. The other is converted to
reverberation by the reverberation processing circuit 8, leveled by the variable resistance
attenuator 9, and added to the mixing amplifier 4. Thus, a signal obtained by adding a singing
voice signal and a signal obtained by adding the reverberation of the singing voice signal to the
accompaniment music signal is emitted from the speaker 12 through the variable resistance
attenuator 10 and the amplifier 11. [Problems to be Solved by the Invention] In such a
conventional example, since the reverberation sound and the performance sound of the singing
voice and the accompaniment are reproduced from the same speaker, the natural presence felt in
an actual hall etc. accompanied by a drop in clarity. There was a drawback of being poor. That is,
the reverberation in the actual hall is a table of reflections where the sound waves of singing
voice and accompaniment music generated on the stage are reflected from the four sides of the

hall while passing through the ceiling, wall, floor, etc. in the hall to reach around the listener. It is
an important element at the bottom, and it plays an important role in creating a natural presence
that brings an atmosphere that envelops listeners, such as echoing and abundance. Therefore, in
live performances, the reverberation sound arrives from a direction different from the direct
sound, whereas in the conventional karaoke performance apparatus, the direct sound and the
reverberation sound are emitted only from the same speaker, ie, from the same direction. It was
difficult to create a natural reverberation effect. The present invention has been made to
compensate for the disadvantages of the prior art as described above, and the purpose of the
invention is to perform on the actual stage of the hall, both for the person who is singing and for
the listener. The present invention is to provide a karaoke performance apparatus which can
obtain a natural, realistic and warm reverberation effect in a natural atmosphere.
[Means for Solving the Problems] Therefore, in the present invention, a means for mixing the
sound signal picked up from the microphone and the sound signal outputted from the sound
source and radiating from the speaker, and the signal branched and inputted from the sound
signal It is characterized in that it comprises means for converting it into a reverberation signal
and emitting it from another speaker group, and furthermore, it mixes the audio signal picked up
by the microphone and the acoustic signal outputted from the acoustic source to make a
loudspeaker , And means for converting the mixed signal into a reverberation signal and emitting
it from another speaker group. The apparatus further comprises means for emitting, from
different speaker groups, an audio signal collected from a microphone, an audio signal output
from an audio source, and a reverberation signal obtained by mixing and converting the audio
signal and the audio signal. Is also characteristic. [Function] Let's reproduce sound field close to
live performance in general room by radiating Reverberation No. 48 created based on input voice
signal from speaker different from speaker playing the singing voice and accompaniment sound
from other speakers It is said that. FIG. 1 is a block diagram of an embodiment of the present
invention. In the figure, music source signals from a playback device group 1 for playing
accompaniment music are applied to a mixing amplifier 4 via an amplifier 2 and a variable
resistance attenuator 3. The singing voice signal picked up by the microphone 5 is branched via
the amplifier 6 and the variable resistance attenuator 7, and is added to the mixing amplifier 4
and the reverberation processing circuit 8. A signal obtained by mixing accompaniment and
singing voice, which is the output of the mixing amplifier 4, is emitted from the speaker 12
through the variable resistance attenuator 10 and the amplifier 11. On the other hand, the
remaining uiB created by passing the singing voice No. 18 to the reverberation processing circuit
8 is appropriately leveled by the variable resistance attenuator 9 and radiated into the room by
the one or more amplifiers Jff 13 and the speaker group 14 respectively. This is an example in
which reverberation is added to the signal of singing voice and reproduced using a dedicated
speaker. As another example, the configuration of FIG. 2 is intended to obtain a more natural
playing effect by adding reverberation to not only the singing voice but also the accompaniment
sound. Here, the accompaniment sound signal and the singing voice signal whose levels are

adjusted appropriately by the variable resistance attenuators 3 and 7 are mixed by the mixing
amplifier 15 and emitted from the speaker 12. The respective signals are adjusted to the level
suitable for reverberation by the variable resistance attenuators 18 and 19, and mixed by the
mixing amplifier 16. Then, the mixed signal is converted into reverberation by the reverberation
processing circuit 8 and emitted from the speaker group 14.
As still another embodiment, the configuration shown in the block diagram of FIG. 3 may be
used. Arrange the accompaniment sounds at the center of the stage and the singing voice at the
center of the stage, and reproduce the reverberation sound from surrounding speakers as it
surrounds the whole room, realizing karaoke performance closer to the actual performance such
as a hall It is possible. The stereophonic sound signal from the playback device group 20 for
playing back the accompaniment music source comprises amplifiers 21 and 22. Variable
resistance attenuators 23 and 24. The light is emitted from the speakers 28 and 29 on the stage
side of the room 47 through the output amplifiers 26 and 27. Here, the three-dimensional sound
signals are added by the adder 25 and applied to the summing amplifier 37 through the variable
resistance attenuator 35. On the other hand, the singing voice by the singer 48 is picked up by
the microphone 5, and a part thereof is emitted from the speaker 34 through the output
amplifier 33 and mixed through the variable resistance attenuator 36 through the amplifier 6
and the variable resistance attenuator 7. It is applied to the amplifier 37. The mixed signal of the
accompaniment sound and the singing voice in the mixing amplifier 37 is converted to a
reverberation signal in the reverberation processing circuit 8 and emitted from the speaker 43 °
44.45.46 through the output amplifiers 39, 40, 41.42. As described above, according to the
present invention, the singing voice, the accompaniment music and the accompanying
reverberation sound in the karaoke performance are radiated to the room from more suitable
directions by the speakers of different systems respectively. A sound field approximate to the
sound field generated in a music hall etc. is created. Therefore, it is possible for listeners and
singers to have a natural feeling of presence as if they were playing in a real hall, and to make
karaoke playing even more enjoyable.
