BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be
described below with reference to the drawings.
Such an embodiment shows one form of the present invention, does not limit the present
invention, and can be arbitrarily changed within the scope of the present invention.
[0015]
A: First Embodiment FIG. 1 is a block diagram showing the configuration of a karaoke apparatus
according to a first embodiment of the present invention.
In the figure, 1 is a microphone for converting vocal sound emitted by a singer into an electric
signal (analog signal) and output, 2 is for converting an analog signal supplied from the
microphone 1 into a digital signal (hereinafter vocal sound signal) A A / D (analog / digital)
converter, 3 is a switching means for switching the destination of the vocal sound signal, and 4 is
a modulator for modulating the vocal sound signal.
[0016]
A storage device 6 stores music data.
As shown in FIG. 2, this music data is composed of a header, a musical tone track, a melody track,
a lyric track, etc., and a track including information on the vibrato effect (hereinafter referred to
as a vibrato track).
Each of these tracks is composed of sequence data consisting of a plurality of event data and
duration data Δt as shown in FIG.
10-04-2019
4
Here, each event data is a MIDI message used for tone formation control or the like.
Each duration data is data specifying a time interval from the use of the immediately preceding
event data for control to the use of the immediately following event data.
[0017]
Next, the vibrato track will be described with reference to FIG.
In this embodiment, for example, when the music is reproduced as shown in FIG. 4A and the
singing is performed as shown in FIG. 4B in accordance with this, the vocal sound obtained from
the A / D converter 2 The signal is frequency-modulated by the modulator 4 to impart a vibrato
effect to the vocal sound.
Frequency modulation of the vocal sound signal is appropriately performed as the music
progresses.
For example, as shown in FIG. 4 (a), FIG. 4 (c) illustrates the timing of the frequency modulation
performed when the music is in progress, and the frequency modulation is performed in the
places marked ON. It is a section, and the place where it describes as OFF is a section where
frequency modulation is not performed.
Thus, the frequency modulation of the vocal sound signal is performed at the timing determined
by the music. In addition, the frequency modulation frequency and modulation depth of the vocal
sound signal are controlled so that the singer-specific vibrato effect can be applied to each music.
The vibrato track includes modulation data for controlling the timing and mode of frequency
modulation of such a vocal sound signal.
[0018]
Here, as shown in FIG. 4 (d), the modulation data is timing information .DELTA.t specifying the
timing of frequency modulation of the vocal sound signal, the modulation frequency of the
10-04-2019
5
frequency modulation to be applied to the vocal sound signal, and the modulation depth. And
frequency modulation control information for specifying. When it is necessary to stop frequency
modulation of the vocal sound signal, predetermined information (for example, frequency
modulation control information in which the modulation depth is 0) is used as frequency
modulation control information.
[0019]
The data format of the vibrato track is in no way different from other tracks. The timing
information is included in the vibrato track as duration data, and the frequency modulation
control information is expressed in the form of MIDI exclusive message and is included in the
vibrato track as event data.
[0020]
Note that with an exclusive message, a flexible number of data bytes can be transferred between
the status "F0H" indicating the beginning of the exclusive and the end of exclusive "F7H", and the
format of the data byte is not specified. It is a message.
[0021]
Next, 7 in FIG. 1 is a MIDI sound source for generating musical tone signals such as
accompaniment sounds.
A mixer 8 mixes and outputs a musical tone signal generated by the MIDI sound source 7 and a
vocal sound signal, and a digital-to-analog (D / A) converter 9 converts a digital signal output
from the mixer 8 into an analog signal. Reference numeral 10 denotes an amplifier for amplifying
the analog signal, and 11 denotes a speaker for outputting the signal amplified by the amplifier
10.
[0022]
A control unit 5 controls the respective units of the karaoke apparatus, and is constituted by a
CPU and its peripheral circuits. At the time of karaoke performance, the control unit 5 controls
10-04-2019
6
the modulator 4, the switching means 3 and the MIDI sound source 7 in accordance with the
music data stored in the storage device 6. Specifically, it is as follows. a. At the time of karaoke
performance, the control unit 5 sequentially reads out event data in music data according to a
sequence program, and sequentially outputs event data such as a tone formation instruction to
the MIDI sound source 7. The MIDI sound source 7 generates a musical tone signal such as an
accompaniment sound of the music according to the event data. b. When the frequency
modulation control information contained in the vibrato track is read out, the switching means 3
is switched to the side 3 a and the frequency modulation control information is supplied to the
modulator 4.
[0023]
Next, the operation of the karaoke apparatus according to the first embodiment will be described.
First, when an instruction to start karaoke performance is given, the control unit 5 sequentially
reads the music data stored in the storage device 6 according to a predetermined sequence
program. Then, when event data such as a tone formation instruction is read out, the control unit
5 supplies the event data to the MIDI sound source 7. Under such control, a musical tone signal
such as an accompaniment sound is generated by the MIDI sound source 7 and output from the
speaker 11 through the mixer 8, the D / A converter 9 and the amplifier 10. When the intro part
of the music is finished, the singer starts singing.
[0024]
The vocal sound emitted by the singer is converted to an analog signal by the microphone 1, and
this analog signal is converted to a digital signal by the A / D converter 2.
[0025]
Here, while the timing information of the vibrato track is not read out by the control unit 5, the
switching means 3 is switched to the 3 b side, and the vocal sound signal is directly supplied to
the mixer 8.
Therefore, during this period, the vocal sound is output from the speaker 11 as it is without
being imparted with a vibrato effect.
10-04-2019
7
[0026]
Thereafter, when the frequency modulation control information instructing any frequency
modulation is read out by the control unit 5, the switching unit 3 is switched to the 3a side by
the control unit 5. Further, the read frequency modulation control information is given to the
modulator 4 by the control unit 5. As a result, the modulator 4 performs frequency modulation of
the vocal sound signal in accordance with the modulation frequency and modulation depth
specified by the frequency modulation control information, and is sent to the mixer 8. Therefore,
thereafter, the vocal sound to which the vibrato effect is applied is outputted from the speaker
11.
[0027]
The above operation is, for example, an operation in a section marked as ON in FIG. FIG. 4B
exemplifies how a vibrato effect is given while the following action is performed while the singer
utters "A ---". In FIG. 4 (b), “~ ~ ~” indicates a vibrato-applied vocal sound output from the
speaker 11.
[0028]
Next, when the frequency modulation information for instructing the modulation stop is read by
the control unit 5, the switching unit 3 is switched to the 3b side by the control unit 5. As a
result, the vocal sound signal from the A / D converter 2 is supplied to the mixer 8 as it is
without passing through the modulator 4. Therefore, thereafter, the vocal sound to which the
vibrato effect is not applied is output from the speaker 11. This operation corresponds to the
operation of the section marked as OFF in FIG. 4 (c).
[0029]
In the present embodiment, as in the example shown in FIG. 4D, a plurality of sets of modulation
data consisting of timing information (duration data) and frequency modulation control
information (event data) are continuously included in the vibrato track. It is also good. In this
case, until the modulation stop instruction is read out, a series of frequency modulation control
information is read out at a time interval designated by the immediately preceding timing
10-04-2019
8
information and supplied to the modulator 4.
[0030]
Therefore, according to the present embodiment, the modulation frequency and modulation
depth of the frequency modulation of the vocal sound signal performed by the modulator 4 can
be sequentially switched by the above series of frequency modulation control information, which
makes the vocal sound complicated. Vibrato effect can be given.
[0031]
The first embodiment may be configured as follows.
(1) In the first embodiment, although the modulator 4 that performs frequency modulation is
used as the modulation unit, a modulator that performs amplitude modulation in addition to
frequency modulation may be used (claim 5). In this case, in addition to timing information and
frequency modulation control information, information for controlling amplitude modulation is
included in the modulation data.
[0032]
(2) In the first embodiment, switching of whether or not to modulate the vocal sound signal is
performed using the independent switching means 3. However, instead of providing the
switching means 3, in the modulator 4, The following control may be performed. a. When no
modulation data is given from the control unit 5, the vocal sound signal from the A / D converter
2 is output to the mixer 8 as it is. b. When modulation data is supplied from the control unit 5,
the vocal sound signal from the A / D converter 2 is modulated according to the modulation data
and output to the mixer 8.
[0033]
(3) The vocal sound signal is modulated only while the switch provided in the operation unit (not
shown) or the switch 12 attached to the microphone 1 is switched to a predetermined state as
shown in FIG. It may be configured as follows. As a result, the singer can apply a vibrato effect to
10-04-2019
9
the vocal sound at any timing. In this case, modulation data does not include timing information,
but includes only frequency modulation control information. Also, for example, a sensor or the
like for detecting vibration may be incorporated in the microphone 1 and modulation of the vocal
sound signal may be performed only while the microphone 1 is shaken up and down and left and
right. According to this configuration, the singer can impart a vibrato effect without shifting the
line of sight from the display on which the lyrics are displayed to the switch 12.
[0034]
(4) As shown in FIG. 6, a plurality of modulators 4-1 to 4-n may be provided. In the karaoke
apparatus shown in FIG. 6, frequency modulation control information for applying modulation in
a predetermined manner to the vocal sound signal is stored in each of the predetermined
modulators 4-1 to 4-n. Modulator selecting means 21 and 22 are provided before and after the
plurality of modulators 4-1 to 4-n, which can switch the modulators that modulate the vocal
sound signal according to the selection of the singer. It is a structure.
[0035]
The music data read from the storage device 6 includes timing information for specifying a
section to which the vocal sound signal is to be modulated, but does not include information for
specifying a mode of modulation (modulation frequency, modulation depth).
[0036]
The control unit 5 reads music data and monitors timing information in the data.
Then, when it becomes a section to modulate the vocal sound signal, the control unit 5 outputs
an instruction to the effect that modulation should be performed to the modulators 4-1 to 4-n.
[0037]
As a result, the modulators selected by the modulator selection means 21 and 22 modulate the
vocal sound signal in accordance with the prestored frequency modulation control information.
[0038]
10-04-2019
10
In the method of selecting any one of the plurality of modulators 4-1 to 4-n, the vibration
provided on the switch 12 or the microphone 1 provided on the operation unit or the
microphone 1 as in the above (3) A sensor that senses can be used.
That is, each time the switch 12 is pressed once, the modulator that applies modulation to the
vocal sound signal may be switched to 4-1 → 4-2 → ... → 4-n. Alternatively, a plurality of
switches corresponding to a plurality of modulators may be provided in the microphone 1 and
switched to a modulator corresponding to the switches when the user presses the switch.
Furthermore, in the case of using a sensor or the like that senses vibration, for example, even
when the user vibrates the microphone 1, the modulator switches to 4-1 → 4-2 → ... → 4-n.
Good.
[0039]
According to this embodiment, it is not necessary to include the frequency modulation control
information in the music data, which leads to the compactness of the music data.
[0040]
The above embodiment may be configured as shown in FIG.
That is, in addition to the plurality of frequency modulators 4-1 to 4-n, a plurality of amplitude
modulators 4a-1 to 4a-n are provided, and a plurality of amplitude modulators 4a-1 to 4a- are
provided as in the above embodiment. Before and after n, modulator selection means 21 and 22
are provided. Thus, it is possible to switch any of the plurality of amplitude modulators 4a-1 to
4a-n and any of the plurality of frequency modulators 4-1 to 4-n by the selection of the singer.
Configure In order to select one amplitude modulator and one frequency modulator, a switch
provided in the microphone or a sensor that senses vibration can be used as in the above
embodiment. Further, any of the selection methods shown in the following a to c may be adopted.
[0041]
10-04-2019
11
a. The user selects one of the plurality of amplitude modulators and independently selects one
of the plurality of frequency modulators.
[0042]
b. When one of the plurality of amplitude modulators is selected, in conjunction with this, one
of the plurality of frequency modulators is selected. That is, for example, in FIG. 7, when the
amplitude modulators 4a-1 to 4a-n correspond to the frequency modulators 4-1 to 4-n,
respectively, and the user selects the amplitude modulator 4a-1. In conjunction with this, the
frequency modulator 4-1 is selected.
[0043]
c. A plurality of combinations of the amplitude modulator and the frequency modulator are
determined, and the user selects one from among these. That is, for example, Singer A amplitude
modulator 4-1 frequency modulator 4-2 Singer B amplitude modulator 4-3 frequency modulator
4-1 singer C amplitude modulator 4-1 frequency modulator 4-4 ... Information indicating
combinations of an amplitude modulator and a frequency modulator capable of giving vibrato
similar to various singers is registered in advance in a memory (not shown). When the user
operates the switch provided on the microphone, information indicating the combination of the
amplitude modulator and the frequency modulator corresponding to the predetermined singer is
read out sequentially, such as singer A → singer B → singer C → ... The amplitude modulator and
the frequency modulator are selected based on the information.
[0044]
According to this embodiment, it is possible to add a more complicated and diverse vibrato to the
vocal sound than the above embodiment.
[0045]
In the first embodiment, the A / D converter 2 converts an audio signal (analog signal) captured
by the microphone 1 into a digital signal and then modulates it, and the D / A converter 9
converts it into an analog signal. Although the configuration is such that the output is made back
and output, the audio signal captured by the microphone 1 may be modulated without providing
10-04-2019
12
the A / D converter 2 and the D / A converter 9.
Further, although the mixer 8 for mixing digital signals is used in the first embodiment, it may be
changed to an analog mixer. In this case, although it is necessary to add a D / A converter
between the MIDI sound source 7 and the mixer 8, the signal processing system that modulates
the audio signal from the microphone 1 and supplies it to the mixer 8 is an analog circuit. It can
be configured.
[0046]
B. Second Embodiment The present embodiment uses the microphone shown in FIG. 8 in the
first embodiment.
[0047]
In FIG. 8, 31 is a microphone body, 32 is a microphone unit, 33 is modulation signal generating
means, 34 is an amplifier, and 35 is an amplitude modulator. The microphone unit 32 is similar
to that used in a normal microphone, and converts vocal sound emitted by a singer into an audio
signal and outputs it. The modulation signal generating means 33 is fixed to the microphone
body 31 and outputs a modulation signal when the singer gives vibration or acceleration to the
microphone body 31. The amplifier 34 amplifies and outputs the modulation signal output from
the modulation signal generation unit 33. The amplitude modulator 35 is configured of, for
example, a variable gain amplifier, and amplitude-modulates and outputs an audio signal
supplied from the microphone unit 32 with a modulation signal output from the amplifier 34.
Each device described above is built in the microphone main body 31.
[0048]
Further, the modulation signal generating means 33 is composed of a piezoelectric element 41, a
spring 42, a damper 43 and a load 44. Here, the piezoelectric element 41 is fixed to the
microphone body 31. One end of the spring 42 is fixed to the piezoelectric element 41. A load 44
is attached to the other end of the spring 42. The damper 43 is for damping the vibration of the
load 44.
10-04-2019
13
[0049]
In such a configuration, when vibration or acceleration is applied to the microphone body 31 by
the singer, the load 44 vibrates and this vibration is transmitted to the piezoelectric element 41
via the spring 42 and the damper 43. The piezoelectric element 41 outputs a modulation signal
when vibration is applied. The modulated signal is amplified by an amplifier 34 and then
supplied to an amplitude modulator 35.
[0050]
The amplitude modulator 35 modulates the audio signal supplied from the microphone unit 32
with the modulation signal supplied from the amplifier 34 and outputs it. The modulated audio
signal is supplied to the karaoke apparatus body, mixed with a musical tone signal such as an
accompaniment sound generated by a MIDI sound source, and then output from a speaker via a
D / A converter and an amplifier.
[0051]
According to this embodiment, a vibrato effect can be added to the audio signal in response to
the operation of the singer moving the microphone body 31. In the present embodiment, the
microphone is provided with means for imparting the vibrato effect, so it is not necessary to
provide an apparatus for imparting the vibrato effect to the karaoke apparatus body. Of course, it
does not prevent providing a means for applying the vibrato effect to both the microphone and
the karaoke apparatus body.
[0052]
The second embodiment may be configured as shown in FIG. FIG. 9 is a diagram showing the
configuration of a modification of the microphone according to the second embodiment of the
present invention. In addition, in each part of the apparatus shown in FIG. 9, about the part
which is common in the apparatus shown in FIG. 8 mentioned above, the same code | symbol is
attached and the description is abbreviate | omitted.
10-04-2019
14
[0053]
The embodiment shown in FIG. 9 differs from the device in the second embodiment only in the
configuration of the modulation signal generation means. In the present embodiment, the
modulation signal generating means is constituted by a flywheel 51, a shaft 52, a support 53 and
a piezoelectric element 41. Similar to the configuration shown in FIG. 8, the piezoelectric element
41 is fixed to the microphone body 31. The flywheel 51 is connected to a support 53 via a shaft
52, and the support 53 is fixed to the piezoelectric element 41 in an upright state.
[0054]
In such a configuration, when vibration or acceleration is applied to the microphone body 31 by
the singer, the flywheel 51 rotates about an axis 52 provided on the support 53. Here, since the
center of gravity of the flywheel 51 is offset from the center of rotation, the rotation of the
flywheel 51 causes vibrations in the support 53, and the vibrations are transmitted to the
piezoelectric element 41 via the support 53. The piezoelectric element 41 outputs a modulation
signal when this vibration is applied. The subsequent operation is similar to that of the second
embodiment.
[0055]
Also in this embodiment, the same effect as that of the second embodiment can be obtained.
[0056]
The microphones shown in FIG. 8 or 9 described above are used in a karaoke apparatus and do
not prevent their application to apparatuses other than the karaoke apparatus.
[0057]
As described above, according to the present invention, since modulation data can be adjusted
for each song, it is possible to impart a vibrato effect to each melody, singer of the song, and
lyrics. Yes (claims 1, 2 and 3).
10-04-2019
15
This makes it easy to copy the original song and provides the singer with pleasure.
[0058]
Further, when modulation data is included as an exclusive message in a part of tracks
constituting music data, the data can be made compact.
[0059]
Further, in the case where the vocal sound signal is configured to be subjected to amplitude
modulation as well as frequency modulation (claim 4), it is possible to apply vibrato with
complicated temporal change to the vocal sound.
[0060]
When the switching means is controlled by switching the switch or the like attached to the
microphone (claim 5), the singer can vibrato the vocal sound at an arbitrary timing.
[0061]
Furthermore, in the case where a plurality of modulators are provided, and different modulation
data are stored, and one of the modulators is specified by three selections of the singer (claim 6),
the frequency modulation control information Since it is not necessary to include in music data,
music data can be made compact.
[0062]
According to the seventh to ninth aspects of the present invention, it is possible to apply vibrato
to the vocal sound in accordance with the operation of the singer moving the microphone.
