2. Description of the Related Art Karaoke devices and the like have been used to practice singing.
When practicing the song, the singer has a microphone and sings a song according to the melody
flowing from the karaoke apparatus while watching the screen on which the lyrics are displayed
or the lyrics card on which the lyrics are written.
[0003]
[Problems to be Solved by the Invention] By the way, when practicing the song, it is said that if
you sing in a low voice like a nausea, the effect of the practice is hardly effective. For this reason,
the practice of singing must be such as to sing a song (with a certain amount of voice or more) by
making a sufficient voice.

[0004]
However, the audio signal (song) input to the microphone is amplified by the amplifier and
output from the speaker. That is, the singer will practice singing while listening to the voice
amplified by the amplifier, not the voice uttered by the singer. Therefore, the singer himself could
not recognize how much voice practice he was practicing, and could not know whether he was
practicing singing effectively.
[0005]
An object of the present invention is to provide a voice level detection device that can practice a
song effectively by informing the singer in itself how much voice practice a song is practiced.
[0006]

joined to the lower side of the hood of the microphone. A transmitter comprising: a voice volume
detector for detecting voice volume of a voice signal inputted to a microphone; and an output
unit for outputting a signal based on a detection value in the voice volume detector wirelessly or
in a wired manner; A receiver comprising: a receiver configured to receive the output signal; and
vibration means configured to vibrate the main body based on the signal received by the
receiver.
[0007]
In this configuration, the transmitting device is held in a state in which the spherical bonding
surface formed on the surface by the mounting means is bonded to the lower side of the hood of
the microphone.
In this state, the voice amount detection unit detects the voice amount of the voice signal input to
the microphone, and the output unit outputs a signal based on the detected voice amount as a
wireless signal or a wired signal.
On the other hand, in the receiving device, the signal output from the transmitting device is
received by the receiving unit, and the receiving device body is vibrated based on the received

signal.
[0008]
Therefore, when practicing the song, if the receiver is put in the chest pocket etc., the singer will
feel a vibration based on his / her voice volume. That is, when practicing a song, the singer can
recognize his / her voice volume from this vibration. Therefore, you can practice singing
effectively. In addition, the transmitting device of this configuration can be attached to any
microphone because the attachment state with the microphone is maintained by the attachment
means. That is, if this voice level detection device is carried, it will be possible to practice the
song effectively anywhere. Furthermore, since the transmitting surface is held in a state where
the spherical junction surface formed on the surface is joined to the lower side of the hood of the
microphone, the influence of the breath accompanying the voice is small in the detection of the
voice volume, and the voice volume Can be accurately detected.
[0009]

The operation of the voice level detection device of this embodiment will be described in detail
below.
In the present specification, the voice volume is the power and voice quality of the voice. The
transmitter 1 is referred to as a microphone (hereinafter referred to as a microphone, as shown
in FIG. 5). ) 20 is attached below the hood portion 21. In the general microphone 20, the hood
portion 21 is formed in a mesh shape by a ferromagnetic material such as iron. The handle 22 is
formed of a nonmagnetic material such as aluminum. Further, as described above, since the
magnet is disposed on the back side of the joint surface 2 of the transmission device 1, when the
hood portion 21 and the joint surface 2 are joined, the joined state is maintained by the magnet.
On the other hand, the receiving device 10 is put in the chest pocket of the singer, etc., and the
vibration of the device body is transmitted to the singer himself.
[0020]
Usually, the singer holds the microphone 20 such that the hood 21 is located slightly below his /
her mouth. And a singer sings a song to a performance such as karaoke. As described above,
since the hood portion 21 of the microphone 20 is formed in a mesh shape, the vibration of air
generated by the singing person's song (speech) is transmitted to the transmitting device 1
attached to the lower side of the hood portion 21. It is transmitted efficiently. The vibration plate
6a provided in the transmission device 1 is vibrated by the transmitted air vibration. The voice
level detection unit 6 detects the voice level of the singer from the vibration level of the
diaphragm 6a.
[0021]
Here, when the transmission device 1 is attached to the upper side of the hood portion 21, the
diaphragm 6a is vibrated also by the breath accompanying the vocalist of the singer, and the
voice amount can not be detected accurately. However, in the present embodiment, since it is
attached to the lower side of the hood portion 21, the distance from the singer's mouth to the
diaphragm 6a is long, and the diaphragm 6a hardly vibrates by the breath accompanying the
vocalist's voice, and the air vibrates by the vocalist The diaphragm 6a is vibrated only by the
above. In other words, the voice volume can be accurately detected without being substantially
affected by the breath accompanying the utterance. The transmitting unit 7 outputs a signal
10-04-2019
6
including data indicating the voice amount detected by the voice amount detecting unit 6 as a
wireless signal (FM wave of about 100 MHz).
[0022]
When the receiving device 10 receives the wireless signal output from the transmitting device 1
by the receiving unit 16, the receiving device 10 reads the amount of voice of the singer from the
received signal. Here, as shown in FIG. 6, the relationship of the amount of vibration (the
relationship of the power supplied to the motor provided in the vibration unit 17) to the amount
of voice is set in the vibration amount control unit 18. This setting is made in advance by
adjustment of the adjustment screw 11. In the example shown in FIG. 6, when the voice volume is
less than the threshold value, the receiving device 2 is not vibrated (no power is supplied to the
motor provided in the vibration unit 17), and when it exceeds the threshold value And shake the
receiver 2. Also, the amount of vibration is changed in proportion to the size of the voice volume.
The vibration amount control unit 18 determines the power to be supplied to the motor provided
in the vibration unit 17 based on the voice amount read out from the transmitted wireless signal.
Then, this electric power is supplied to the motor of the vibration unit 17, and the main body of
the receiving device 10 is vibrated (however, when the voice amount does not exceed the
threshold value, the electric power is not supplied to the motor and the vibration does not occur).
[0023]
As described above, since the receiver 10 is placed in the chest pocket or the like of the singer
himself, the vibration of the receiver body 10 is transmitted to the singer himself. Therefore,
when the user does not feel the vibration of the receiving device 10, the singer can recognize
that the amount of voice is insufficient. In addition, if the detected voice volume exceeds the
threshold, the singer can recognize the volume of the voice volume from the vibration volume of
the receiving device 10.
[0024]
As described above, in the voice volume detection device of the present embodiment, the voice
volume of the singer is detected by the transmitting device 1 attached to the microphone 20, and
the receiving device 10 placed in the chest pocket of the singer based on the voice volume
10-04-2019

detected. It was made to shake. In addition, since the receiving device 10 is configured not to
shake if the voice volume is insufficient (if it is equal to or less than the threshold), the singer can
easily recognize whether he / she sings with a sufficient voice volume. On the other hand, even
when the voice volume exceeds the threshold value, the vibration volume of the receiving device
10 is changed in proportion to the voice volume, so how much the voice volume of the receiver
10 is from the vibration of the receiving device 10 to feel Can also be recognized. Therefore, the
singer can recognize the amount of voice at the time of singing a song, and it is sufficient to
change the utterance so as to increase the amount of voice if the amount of voice is not
sufficient. There is no need to practice, and you will be able to practice the song efficiently. In
addition, the singer is made to recognize whether or not the voice volume is sufficient by the
vibration, so that the singer can write the displayed screen or the lyrics of the lyrics to check
whether the voice volume is sufficient. There is no need to look away from lyrics cards etc. That
is, even if the song does not remember the lyrics can practice the song effectively.
[0025]
Next, another embodiment of the present invention will be described. The difference between this
embodiment and the above-described embodiment is the relationship of the amount of vibration
to the amount of voice set in the vibration amount control unit 18. In this embodiment, as shown
in FIG. 7, the receiving apparatus 10 is not vibrated as in the above-described embodiment when
the detected voice volume is equal to or less than the threshold, but when the voice volume
exceeds the threshold, the receiving apparatus 10 is shaken a certain amount. It is the point that
it is made to shake in quantity. That is, the singer recognizes that the amount of voice is
sufficient if the receiving device 10 is vibrating, and recognizes that the amount of voice is not
sufficient if the receiving device 10 is not vibrating. Although the singer can not recognize the
size of the voice volume from the vibration volume of the receiving device 10 as in the abovedescribed embodiment, the circuit for supplying power to the motor provided in the vibration
unit 17 can be easily configured ( In this embodiment, the circuit can be configured to turn on
and off the power to the motor, and the circuit to change the amount of power supplied to the
motor is unnecessary.
[0026]
In addition, another embodiment of the present invention will be described. The difference
between this embodiment and the first described embodiment is the relationship of the amount
of vibration to the amount of voice set in the amount-of-vibration control unit 18. In this
embodiment, the receiver 10 is not vibrated when the detected voice volume is below the
10-04-2019
8
threshold as shown in FIG. 8, and the vibration volume of the receiver 10 is changed in
proportion to the voice volume when the voice volume exceeds the threshold. Although they are
common, they differ in that the receiving apparatus 10 is not vibrated when the voice volume
becomes larger than the maximum value (threshold <maximum value) set separately from the
threshold. That is, this embodiment is configured to shake the receiving device 10 when the voice
volume is between the threshold value and the maximum value. In this configuration, it is
possible to recognize that the voice volume is extremely large or to the singer. For example, since
practicing a song with a screaming voice has no effect, the receiver 10 is configured not to shake
even when the voice volume is such. That is, the singer can practice the song with an appropriate
amount of voice and can practice the song more effectively.
[0027]
Further, the relationship of the amount of vibration to the amount of voice shown in FIG. 9 may
be set in the amount-of-vibration control unit 18. This is the relationship between the amount of
vibration and the amount of voice when the receiver 10 is not vibrated even when the amount of
voice mentioned above becomes the maximum value or more in the second embodiment
described above.
[0028]
In addition, another embodiment of the present invention will be described. In this embodiment,
a voice amount detection device is configured by one transmitting device 1 and a plurality of
receiving devices 10. The transmitter 1 has the same configuration as that of the above-described
embodiment. On the other hand, the receiving device 10 is different from the above embodiment
in the configuration. FIG. 10 is a view showing the appearance of the receiving apparatus
according to this embodiment, and FIG. 11 is a block diagram showing the configuration of the
receiving apparatus. The receiving device 10 of this embodiment differs in appearance from
those of the embodiments described above in that a plurality of LEDs 12 are provided on the
surface. The structurally different points are that the vibration unit 17 and the vibration amount
control unit 18 are not provided, and the lighting control unit 19 for controlling the lighting of
the LED 12 is provided. The voice amount detection device of this embodiment is used, for
example, in a throat competition. Unlike the embodiment described above, the receiving device
10 is not put in the chest pocket of the singer himself, but is passed to a judge who examines the
singer's song. The receiving devices 10 are prepared as many as the number of judges, and one
receiving device 10 is delivered to each judge.

[0029]
On the other hand, the transmitter 1 is attached to the microphone 20 and used as in the abovedescribed embodiment. The operation of the transmission apparatus 1 is the same as that of the
above-described embodiment, and thus the description thereof is omitted here. Each receiving
device 10 receives the radio signal transmitted from the transmitting device 1 without being
affected by the other receiving devices 10, and performs the following processing. When the
receiving device 10 receives the wireless signal output from the transmitting device 1 by the
receiving unit 16, the receiving device 10 reads the amount of voice of the singer from the
received signal. The lighting control unit 19 controls lighting of the LED 12 based on the read
voice amount. Here, in the lighting control unit 19, the number of LEDs 12 to be lighted for the
voice volume is set in advance. That is, the lighting control unit 19 determines the number of
LEDs 12 to be lit from the detected voice amount, and turns on the determined number of LEDs
12. That is, in this embodiment, the number of LEDs 12 to be lit is changed based on the detected
voice amount. Therefore, the judge can accurately recognize how much the singer's voice is from
the number of lighted LEDs 12 provided on the surface of the receiving device 10, and the
examination can be easily performed.
[0030]
In this way, if it is used for the examination of the throat contest etc., it is possible to make the
judge correctly recognize the volume of the singer's voice. In this embodiment, the receiving
device 10 changes the number of lighting of the LED 12 based on the detected voice amount, but
the detected voice amount may be displayed by a level meter, or the vibration may be generated
as in the above embodiment. It may be
[0031]
The transmitter 1 may be attached to the surface of a ring 30 formed of metal, leather, rubber, or
plastic as shown in FIG. 12 (A). If configured in this way, as shown in FIG. 12 (B), if the singer
wears the ring 30 on the thumb of the hand holding the microphone and practices singing,
whether or not his voice volume is appropriate Can be recognized from the vibration of the
receiving device 12, and an effective song practice can be performed as in the above-described
embodiment. Further, in this case, there is no need to form the joint surface 2 in the transmitter
1 (no spherical processing is required), and there is no need to arrange a magnet inside, so the
10-04-2019
10
cost of the transmitter 1 is increased. The cost is lower than that of the above embodiment.
[0032]
In the embodiment described above, the receiving device 10 is vibrated by the motor, but the
receiving device 10 may be vibrated using a piezoelectric element or the like without being
limited to this. In addition, although the adjustment of the threshold is performed by the
reception device 10, the adjustment of the threshold may be performed by the transmission
device 1. In addition, although it is described that the transmitting device 1 and the microphone
20 are held in a joined state by the magnet, the transmitting device 1 is formed in a shape to be
fitted to the microphone 20 and fitted to the microphone 20 by fitting. You may attach it.
Further, in the above-described embodiment, the receiving device 20 is a card type, but the
present invention is not limited to this shape. Furthermore, the transmission device 1 and the
reception device 10 may be connected by wire.
[0033]
As described above, according to the present invention, the amount of voice of a singer or the
like is detected, and the receiving apparatus main body is vibrated based on the detected amount
of voice. If the receiver is put in the chest pocket etc., it is possible to make the singer feel a
vibration based on his / her voice volume. That is, the singer can recognize his / her voice
volume while practicing the song. Therefore, practice of the song can be done effectively. In
addition, because it is made to recognize whether the voice volume is enough by vibration,
whether the voice volume is enough without looking away from the screen or the lyrics card on
which the lyrics are displayed when singing a song Can be recognized. Therefore, even if the
song does not remember the lyrics can be practiced effectively. In addition, the transmitting
device of this configuration can detect the voice volume with little influence by the breath
accompanying the utterance. Furthermore, it can be attached to any microphone, and if you carry
this voice level detection device, you can practice singing effectively anywhere.
