DESCRIPTION JPH08272383
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
karaoke terminal device capable of adjusting voice and playing effects.
[0002]
2. Description of the Related Art In a conventional karaoke terminal device, when using so-called
effector functions that change the playing effects by adding echoes to voices and playing, each
time the user considers the sound quality and the atmosphere of his own taste and music. I
manually operated the volume for echo adjustment.
[0003]
In addition, echo and the like are uniformly changed at the same delay rate and the like with
respect to the entire frequency band of sound.
[0004]
However, the conventional karaoke terminal device has the following problems.
That is, when changing the playing effect, it was troublesome because it was a manual operation.

In addition, since the echo etc. changes by a fixed amount over the entire frequency band as
described above, when it is centered on a specific sound such as singing voice, the performance
balance with the instrument or other sounds can not be obtained, and the user There were times
when I could not make it to my favorite sound quality or atmosphere. For example, if the delay
time of the echo of the singing voice is too long, there is a problem that it becomes difficult to
hear the high sound of the instrument.
[0005]
An object of the present invention is to provide a karaoke terminal device that allows a user to
easily perform adjustment operations without losing the balance between voice and performance.
[0006]
A karaoke terminal device according to the first aspect of the present invention is an karaoke
terminal device for adjusting voice and performance effects by processing an audio signal,
comprising: amplifying means for amplifying the voice signal and the performance signal
according to frequency bands; Storage means for storing the amplification degree of each
frequency band by the means as a pattern, selection means for selecting the pattern, and a
pattern selected by the selection means from the storage means and controlling unit for
instructing the amplification means to perform acoustic processing And
[0007]
A karaoke terminal device according to a second aspect of the present invention is a karaoke
terminal device for adjusting voice and performance effects by processing an audio signal,
comprising: delay means for delaying the audio signal and performance signal for each frequency
band; A storage unit for storing as a pattern, a selection unit for selecting the pattern, and a
control unit for reading out the pattern selected by the selection unit from the storage unit and
instructing the delay unit to perform an acoustic process.
[0008]
According to the first aspect of the invention, the storage means stores the amplification degree
of the sound signal and the performance signal amplified by the amplification means as patterns
for each frequency band.

When the user selects this pattern by the selection unit, the control unit reads the selected
pattern from the storage unit and instructs the amplification unit to perform an acoustic process.
Therefore, since the sound can be adjusted for each frequency band, a pattern can be created so
that the balance between voice and performance is not lost, and it can be stored and selected in
the device in advance instead of being created for each performance. There is provided a karaoke
terminal device that allows a user to easily perform adjustment operations.
[0009]
According to the invention 2, in place of the amplification process of the sound process in the
invention 1, the delay process is similarly performed.
Therefore, as in the first aspect of the invention, the adjustment operation by the user is easily
performed without losing the balance between the voice and the performance.
[0010]
DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 is a block diagram showing an
embodiment of the present invention. The audio signal from the microphone 1 and the
performance signal from the sound source unit 4 by the performance control unit 3 are
respectively input to the effector unit 5 described later through the preamplifiers 2a and 2b,
where the emphasis and delay processing of the sound ( After the sound processing, the signal is
amplified by the main amplifier 6 and output to the speaker 7 as a synthesized sound.
[0011]
FIG. 2 is a block diagram of the above-mentioned effector unit 5. As shown in FIG. The function of
the effector unit 5 is to adjust the sound quality and the delay for each frequency band of sound.
In this embodiment, the voice and the performance signal (sound signal) are divided into three
frequency bands of low, middle and high respectively, but the same is true even if the division of
the frequency bands is otherwise.

[0012]
Reference numerals 8a to 8c and 9a to 9c denote low pass filters (8a, 9a), band pass filters (8b,
9b), and high pass filters (8c, 9c), respectively, for dividing an audio signal and a performance
signal into frequency bands. 18a-18c and 19a-19c are low frequency band amplification / delay
units (18a, 19a), respectively, for amplifying / delaying audio signals and performance signals
divided into low, middle and high frequency bands, respectively. Frequency band amplifiers /
delays (18b, 19b) and high frequency band amplifiers / delays (18c, 19c). The respective
amplification / delay units are controlled by the main control unit 10.
[0013]
An amplification / delay degree data storage unit 12 sets and stores the degree of amplification
(amplification degree) of each amplification / delay unit and the degree of delay (degree of delay)
in advance as some effect patterns. . This pattern is selected by the user from the keyboard,
button switch, etc. by the amplification / delay selection unit 11. A mixer 13 synthesizes the
signals amplified / delayed separately for each frequency band as described above. The signal
synthesized here is amplified by the main amplifier 6 and output to the speaker 7.
[0014]
That is, the user operates the amplification / delay selection unit 11 to select a desired effect
pattern. This pattern is, for example, "a concert-hole-like sound", "a sound fit to a rock tune", "a
sound fit to an enka tune" or the like. Thus, the control unit 10 reads data corresponding to the
selected pattern from the amplification / delay data storage unit 12 and sends the data to the
respective amplification / delay units, so that a performance is performed based on the pattern
selected by the user.
[0015]
According to the present invention, according to the user's selection, the sound is processed
according to the patterns of the amplification degree (invention 1) and the delay degree
(invention 2) for the voice and the performance signal stored for each frequency band. Therefore,
with a simple operation, it is possible to provide a playing effect that matches the taste of the

user and the mood of the song.
