Description

  The present invention can individually set whether or not to listen to the accompaniment sound and the singing voice for each listening area when a plurality of customers form a group and gather in different listening areas for each group. It relates to a possible karaoke system.

  In recent years, karaoke devices have been widely used in karaoke boxes and snack stores. One karaoke box is a single listening area, and a single group can occupy a singing along with karaoke accompaniment. On the other hand, in a snack store or the like, a plurality of customers often form groups for each table and enjoy singing according to karaoke accompaniment for each group. In this case, although a different listening area is formed for each table, in each listening area, not only the singing voices of the members of the own group but also the singing voices of the members of the other groups can be heard.

In such a situation, there is a case where it is desired to selectively listen to the accompaniment sound of the currently played music or the singing voice singing along with this music.
For example, when a member of his group is singing, he wants to hear the singing voice, but when a member of another group is singing, he / she does not listen to the singing voice. There may be a chat within a group. In this case, the singing voices of the members of other groups are in the way for the group that is chatting.

  Also, even when other group members are singing, there are various cases such as when you want to hear the singing voice and accompaniment sound, or when you do not want to hear the singing voice but want to hear only the accompaniment sound. There is a demand.

  Thus, a karaoke apparatus is disclosed in which a directional speaker capable of beam control is used to distinguish and listen to sound for each of a plurality of tables (see Patent Document 1). The technique described in Patent Document 1 performs beam control on sound output from a directional speaker so that a singer's voice can be heard only at the table of the singer and its group, and at other tables. The guide vocal can be heard along with the accompaniment sound.

JP 2005-173137 A

  However, although the technique described in Patent Document 1 described above can sing a singing voice only to a table of a specific group, an accompaniment sound and a guide vocal can be heard from a table of another group.

  In addition, when an accompaniment sound is output using a general audio speaker, a high-quality and powerful accompaniment sound is obtained, but when an accompaniment sound is output from a directional speaker, a general audio speaker is generated. Compared to this, the sound quality is inferior and the accompaniment sound is not powerful.

  As mentioned above, when multiple groups are mixed and enjoying karaoke, when members of other groups are singing, they may chat within their own group. In some cases, accompaniment sounds and guide vocals could get in the way. In addition, even in other groups, there is a case where the user wants to hear the singing voice, and there is a case where the user does not want to listen to the singing voice but wants to sing himself according to the accompanying sound.

  The present invention has been proposed in view of the above-described circumstances.
