Needless to say, the wireless microphone is used in combination with the receiving device, and it
is necessary to match the transmission channel and the reception channel. In the karaoke
collective store, interference is prevented by making the channels used for the wireless
microphones installed in one guest room different from the channels used for the wireless
microphones installed in the next room. Patents 3806699, 3806700, 2003-244008 and 6326621 disclose inventions intended to enable such channel selection and setting to be
performed simply and without fail. It is done.
[0003]
=== ID Registration of Requester Person === As well known, in the queue of performance
reservation in the karaoke apparatus, the user ID of the requester person can be registered along
with the music piece ID of the request music piece. Various systems for realizing it have been
developed and widely used for practical use, and have become one of the standard functions of
karaoke (Japanese Patent No. 3143456, Japanese Patent No. 3422688, Japanese Patent No.
3573422, Patent No. 3949624, the patent No. 4050216).
[0004]
With this function, it is possible to record karaoke usage results for each user, and combine this
with the personal information database of the user to implement a wide variety of personalized
services (Japanese Patent No. 4319054, Patent No. 4041049) Gazette, Patent No. 3964335).
[0005]
=== Cause of the Invention === As is well known, the bowling alley is equipped with balls of
various characteristics as standard, and the user plays a game by selecting a ball that is suitable
for him.
However, avid bowling enthusiasts are not satisfied with the standard-equipped balls, but they
own their own balls (specially called "My Balls"), which they custom-made at a specialty store,
and bring their own balls to the bowling alley. Play a game.

The inventor was inspired by the bowling ball and invented the karaoke microphone (personal
microphone). An avid karaoke enthusiast goes to a specialty store to get a detailed measurement
of his voice quality and explains the preference of his voice to be loudened by the karaoke
machine, and a purposefully tailored frequency-sensitive microphone Have them made. This is a
personal microphone, which you bring to a karaoke shop and use it as your own microphone.
[0007]
Due to its portability, the personal microphone is a wireless radio microphone, and is compatible
with the wireless microphone receiver attached to the karaoke apparatus. In this case, it is
necessary to switch the use channel of one karaoke accessory microphone to a channel for
personal microphone when using a personal microphone, and to disable the karaoke accessory
microphone while using a personal microphone.
[0008]
In addition, assuming that many karaoke lovers will have personal microphones, it is also
necessary to consider that the personal microphones of the users in the next room in the karaoke
set-up store may experience interference. In order to reduce this probability of interference, the
channels of personal microphones for sale can not be shared. In a specialty store, it is necessary
to adopt a sales method in which one channel randomly selected from a plurality of allocated
channels is set as one personal microphone.
[0009]

[0011]
=== Outline of Karaoke Device === FIG. 1 shows a schematic configuration of a karaoke device
according to an embodiment of the present invention. In the following, in order to eliminate the
redundancy of the description, the statements regarding the standard well-known and customary
techniques of karaoke machines are kept to a minimum. The main computer 1 controls the
overall control and data processing of the karaoke apparatus. The storage system 2 includes a
hard disk drive, and stores programs, databases, various data, and the like.
[0012]
The user interface 3 is a functional element that displays various types of information to the user
under control of the main computer 1 and receives input of information from the user. The user
interface 3 is an operation panel, remote control, tablet computer that handles karaoke index

database This device etc. The communication interface 4 enables communication with the
karaoke host device and the karaoke database server through the Internet or VPN.
[0013]
According to the control of the main computer 1, the video system 5 displays karaoke video
works and lyrics subtitles at the time of karaoke performance, displays various video information
between songs, and displays one of the display functions of the user interface 3. I also share the
department. The sound system 6 generates karaoke accompaniment music according to the
control of the main computer 1, mixes the singing voice signal from the wireless microphone
reception device 7 with the accompaniment music, and outputs the sound from the speaker.
[0014]
=== Configuration of Wireless Microphone Reception Device 7 === FIG. 2 shows the
configuration of the wireless microphone reception device 7 according to the embodiment of the
present invention. The standard karaoke apparatus can simultaneously use two attached wireless
microphones, and this embodiment is also similar. Since the two wireless microphones in this
case use different channels so as not to cause interference, the receiver 7 includes two receiving
circuits respectively corresponding to the two wireless microphones.
[0015]
One of the receiving circuits is not compatible with personal microphones and has a standard
configuration. That is, the antenna signal is input to the selective tuning circuit 12 through the
high frequency amplifier 11, the frequency signal corresponding to the specific channel selected
here is input to the demodulation circuit 13, and the singing voice signal acoustically input to the
wireless microphone is the demodulation circuit 13 and is input to the mixing amplifier 61 of the
sound system 6. The microcomputer 14 controls the selective tuning circuit 12 to be a channel
corresponding to the setting state of the channel selection switch 15 which is manually switched.
[0016]
01-05-2019

Another receiving circuit is a personal microphone compatible type according to the subject
matter of the present invention. In FIG. 2, the configurations of the high frequency amplification
circuit 21, the selective tuning circuit 22, the demodulation circuit 23, the microcomputer 24
and the channel selection switch 25 are basically the same as above, but the channel control
function performed by the microcomputer 24 is different. The difference is that the detection
circuit 26 is attached to the tuning circuit 22.
[0017]
As will be described later, the main computer 1 supplies a channel designation signal to the
microcomputer 24. The microcomputer 24 controls the selective tuning circuit 22 according to
the channel designation signal and the setting state of the channel selection switch 25 to select a
plurality of channels. Decide on one of the receiving channels. Specifically, when the channel
designation signal from the main computer 1 indicates that the channel is to be switched to the
default channel, the microcomputer 24 sets the channel set by the channel selection switch 25 as
a reception channel. When the channel designation signal includes a channel ID, the
microcomputer 24 sets the channel corresponding to the channel ID as a reception channel.
[0018]
The detection circuit 26 outputs a detection signal indicating whether or not the carrier wave of
the reception channel is detected at a predetermined level or more in the selective tuning circuit
22, and inputs the detection signal to the main computer 1.
[0019]
=== About the user database === As described in the background art section, the karaoke
apparatus can access the user database describing various personal information related to the
user by using the user ID as a key. .
The user database is stored in a host device or database server on the network, and the karaoke
device can be accessed at any time and can download necessary information.
[0020]
01-05-2019

In the present invention, it is necessary for the user database to include a description in which
the user ID and the channel ID are associated with each other as the information on the person
who has registered using the personal microphone. This is one element that characterizes the
present invention. Here, the channel ID is an ID for specifying a transmission channel of a
personal microphone owned by a person who has registered using the personal microphone. For
example, 20 channels are allocated for personal microphones sold by specialty stores, and one
randomly selected channel is set to one personal microphone sold. The channel ID identifies the
channel.
[0021]
=== Control Sequence Associated with Karaoke Performance === The main computer 1 plays the
karaoke music in the order of the music IDs registered in the performance reservation queue. As
well known, in the queue, the user ID of the person who made the request can be registered in
association with the music ID of the request music.
[0022]
When the main computer 1 does not associate a user ID with the music ID prior to the
performance of the requested music, the main computer 1 does not perform control for personal
microphone correspondence, and sets the default channel to the microcomputer 24 by the
channel designation signal. Command to set.
[0023]
Prior to the performance of the requested music, when the user ID is associated with the music
ID, the main computer 1 checks whether or not the user ID and the channel ID are associated in
the user database.
This process can be realized by a method of inquiring the server managing the user database.
Also, the database server creates the user ID / channel ID correspondence table as needed based
on the user database, distributes the correspondence table to each karaoke device as needed, and
the karaoke device stores the correspondence table in the storage system 2 This can also be
realized by a method in which the correspondence table is searched prior to the performance of
01-05-2019

the request music. Even in the latter case, it can be said that the karaoke apparatus is accessing
the user database.
[0024]
If there is no correspondence description between the user ID and the channel ID, the requester
of the music to be played is not registered for using the personal microphone. In this case, the
main computer 1 instructs the microcomputer 24 to set a default channel by a channel
designation signal.
[0025]
If there is a correspondence description between the user ID and the channel ID, the requester of
the music to be played is likely to sing with his own personal microphone. In this case, the main
computer 1 sends a channel designation signal including the channel ID to the microcomputer
24 to set the selective tuning circuit 22 to the corresponding channel. Then, although one of the
microphones attached to the karaoke apparatus can not be used, it is preferable to be able to
easily identify which one of the two microphones is unavailable when using a personal
microphone.
[0026]
Even if the receiving channel is switched for the personal microphone that the requester would
have, it is possible that the person does not bring his own personal microphone. In that case,
even if the performance of the requested music is started, the detection circuit 26 does not
output a signal indicating the detection of the carrier wave of the reception channel. If so, when
approaching the singing section, the main computer 1 instructs the microcomputer 24 to set a
default channel by the channel designation signal.
[0027]
As is well known, karaoke music data is provided with a sign code for discriminating the
temporal composition of music such as a prelude section, a first singing section, an interplay
section, a second singing section, and a backing section Gazette Gazette), control the timing of
returning from the channel for personal microphone to the default channel using this sign code.
