The present invention relates to a karaoke apparatus that assumes the situation of use.

=== Channel selection / setting ===
As is well known, many channels are assigned to a general 800 MHz band wireless microphone system. Needless to say, the wireless microphone is used as a set with the receiving apparatus, and it is necessary to match the transmission channel and the reception channel. In a karaoke gathering store, the channel used by a wireless microphone provided in one guest room is different from the channel used by a wireless microphone provided in an adjacent room to prevent interference. Inventions that are intended to allow such channel selection and setting without fail are described in Japanese Patent Nos. 3806699, 3806700, 2003-244008, and 6-326621. Has been.

=== ID registration of requesting person ===
As is well known, the user ID of the requesting person can be registered together with the song ID of the requested song in the performance reservation queue in the karaoke apparatus. Various systems for realizing this have been developed and put into practical use, and have become one of the standard functions of karaoke (Japanese Patent No. 3143456, Japanese Patent No. 3422688, Japanese Patent No. 3573422, (Japanese Patent No. 3949624, Japanese Patent No. 405216).

  With this function, it is possible to record the karaoke use results for each user, and in combination with the personal information database of the user, various services for individuals can be implemented (Japanese Patent No. 4319054, Japanese Patent No. 4041049). No., Patent No. 3964335).

=== Trigger of invention ===
As is well known, balls of various characteristics are standard equipment in the bowling alley, and the user selects a ball suitable for him from among them and plays a game. However, enthusiastic bowling enthusiasts are not satisfied with the standard balls, they own their own custom-made balls (this is called my balls) and bring them to the bowling alley. And have a game.

  The inventor invented the karaoke my microphone (personal microphone) inspired by the bowling my ball. An enthusiastic karaoke enthusiast goes to a specialty store to measure their voice quality in detail and explains the preference of his voice that is amplified by the karaoke equipment, and a microphone with frequency characteristics adjusted for his purpose. Have you made. This is a personal microphone. Bring it to a karaoke shop and use it as your own microphone.

  The personal microphone is a radio wave type wireless microphone because of its portability, and is adapted to the wireless microphone receiver attached to the karaoke apparatus. In this case, it is necessary to switch the channel used for one karaoke-attached microphone to a personal microphone channel when using a personal microphone, so that the karaoke-attached microphone cannot be used while the personal microphone is used.

  Also, assuming that many karaoke enthusiasts have personal microphones, it is necessary to consider that personal microphones of users in adjacent rooms in a karaoke gathering store may interfere with each other. In order to reduce this interference probability, it is not possible to share the channels of personal microphones to be sold. In a specialty store, it is necessary to adopt a sales method in which one channel randomly selected from a plurality of assigned channels is set to one personal microphone.

=== Outline of Karaoke Equipment ===
FIG. 1 shows a schematic configuration of a karaoke apparatus according to an embodiment of the present invention. In the following, in order to eliminate the redundancy of the description, the description about the standard well-known and conventional technique of the karaoke apparatus is minimized. The main computer 1 supervises the overall control and data processing of the karaoke apparatus. The storage system 2 includes a hard disk device and stores programs, databases, various data, and the like.

  The user interface 3 is a functional element that displays various types of information to the user under the control of the main computer 1 and receives input of information from the user. The user interface 3 is a tablet computer (electronic contents table) that handles an operation panel, a remote controller, and a karaoke index database. This device). The communication interface 4 enables communication with a karaoke host device or a karaoke database server through the Internet or VPN.

  In accordance with the control of the main computer 1, the video system 5 displays karaoke video works and lyric subtitles during karaoke performance, displays various video information between songs, and displays one of the display functions of the user interface 3. The division is also shared. The acoustic system 6 generates karaoke accompaniment music according to the control of the main computer 1, mixes the singing voice signal from the wireless microphone receiver 7 with the accompaniment music, and outputs the sound from the speaker.

=== Configuration of Wireless Microphone Receiver 7 ===
FIG. 2 shows the configuration of the wireless microphone receiver 7 according to the embodiment of the present invention. The standard karaoke apparatus can use two attached wireless microphones simultaneously, and this embodiment is also the same. Since the two wireless microphones in this case use different channels so as not to interfere with each other, the receiving device 7 includes two receiving circuits respectively corresponding to the two wireless microphones.

  One receiving circuit is not compatible with a personal microphone and has a standard configuration. That is, the antenna signal is input to the selective tuning circuit 12 via 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 input to the mixing amplifier 61 of the acoustic system 6. The microcomputer 14 controls the selective tuning circuit 12 so that the channel corresponds to the setting state of the channel selection switch 15 that can be manually switched.

  Another receiving circuit is a personal microphone compatible type according to the gist of the present invention. In FIG. 2, the configuration of the high-frequency amplifier circuit 21, the selective tuning circuit 22, the demodulator circuit 23, the microcomputer 24, and the channel selection switch 25 is basically the same as that described above. The difference is that a detection circuit 26 is attached to the tuning circuit 22.

  As will be described later, the main computer 1 gives a channel designation signal to the microcomputer 24, and the microcomputer 24 controls the selective tuning circuit 22 in accordance with the channel designation signal and the setting state of the channel selection switch 25, so Is determined as a reception channel. Specifically, when the channel designation signal from the main computer 1 is an instruction to switch to the default channel, the microcomputer 24 sets the channel set by the channel selection switch 25 as the reception channel. If the channel designation signal includes a channel ID, the microcomputer 24 sets the channel corresponding to the channel ID as a reception channel.

  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 higher in the selective tuning circuit 22, and inputs this detection signal to the main computer 1.

=== About User Database ===
As described in the background section, the karaoke apparatus can access a user database in which various personal information related to the user is described 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 necessary information can be downloaded.

  In the present invention, the information relating to the person who has registered for use of the personal microphone needs to include a description in which the user ID is associated with the channel ID in the user database. This is one element that characterizes the present invention. Here, the channel ID is an ID that identifies a transmission channel of a personal microphone owned by a person who has registered for personal microphone use. For example, 20 channels are allocated for personal microphones sold by specialty stores, and one randomly selected channel is set for one personal microphone to be sold. The channel ID identifies the channel.

=== Control sequence associated with karaoke performance ===
The main computer 1 plays karaoke songs in the order of the song IDs registered in the performance reservation queue. As is well known, the user ID of the requested person can be registered in the queue in association with the song ID of the requested song.

  When the user ID is not associated with the song ID prior to the performance of the requested song, the main computer 1 does not perform control for the personal microphone and sets the default channel to the microcomputer 24 by the channel designation signal. Command to set.

  Prior to the performance of the requested song, the main computer 1 checks whether or not there is a correspondence between the user ID and the channel ID in the user database when the user ID is associated with the song ID. This process can be realized by inquiring a server that manages the user database. The database server creates a 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 searching the correspondence table prior to the performance of the requested song. Even in the latter case, it can be said that the karaoke apparatus is accessing the user database.

  When there is no correspondence description between the user ID and the channel ID, the requester of the music to be played has not registered for personal microphone use. In this case, the main computer 1 instructs the microcomputer 24 to set a default channel by a channel designation signal.

  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 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. In this case, one of the microphones attached to the karaoke apparatus cannot be used, but it is preferable to easily identify which of the two microphones cannot be used when the personal microphone is used.

  Even if the receiving channel is switched for the personal microphone that the requesting person may have, the person may not bring his own personal microphone. In this case, even if the performance of the requested music is started, a signal indicating detection of the carrier wave of the reception channel is not output from the detection circuit 26. If so, the main computer 1 instructs the microcomputer 24 to set to the default channel by the channel designation signal when it approaches the singing section.

  As is well known, the karaoke music data includes a sign code for distinguishing the temporal composition of the music such as the prelude section, the first song section, the interlude section, the second song section, and the follower section (Japanese Patent No. 3320009). The timing of returning from the personal microphone channel to the default channel is controlled by using this marker code.

  If the above-described control sequence executed by the main computer 1 is arranged, it can be expressed as a flowchart of FIG.
