Japanese Patent Laid-Open No. 10-78780

  However, in the conventional portable karaoke performance device, the karaoke person confirms the singer and the position of the next tune every time the performance of one tune is finished, and the karaoke performance device is operated by the singer. The operation for starting the performance of the next piece of music had to be performed.

  In addition, since the karaoke performance device is moved by human power, even if the weight of the device itself is reduced, it takes a lot of labor to move it frequently by human power. Furthermore, the karaoke person in charge has to confirm the singer and position of the next music piece when the performance of the first music piece is finished, and this also requires labor.

  The present invention has been proposed in view of the above-described circumstances, and an object of the present invention is to provide a mobile karaoke performance device capable of accurately moving a karaoke performance device to a singer who is singing. To do.

  The mobile karaoke performance apparatus of the present invention has the following features in order to achieve the above-described object. That is, the mobile karaoke performance device of the present invention is a mobile karaoke performance device that is accompanied by a performance mechanism in which the lyrics display function and the audio function are integrated, and is self-propelled to the position of the wireless microphone. A data acquisition unit, a current position data acquisition unit, and a self-running control unit are provided.

  The microphone position data acquisition means is means for acquiring microphone position data based on radio waves transmitted from the wireless microphone. The current position data acquisition means is means for acquiring current position data of the karaoke performance device. Based on the current position data acquired by the current position data acquisition means, the microphone position data acquired by the microphone position data acquisition means, and the movement path connecting both positions, the self-propelled control means performs karaoke performance to the position of the wireless microphone. It is a means for making a device self-propelled.

  In addition to the above-described configuration, a performance control unit may be further provided. The performance control means compares the microphone position data of the wireless microphone acquired by the microphone position data acquisition means with the current position data acquired by the current position data acquisition means, and if the two match, the performance of the reserved music is automatically performed. Means for controlling the performance mechanism to be initiated.

  In addition to the above-described configuration, a microphone information management unit may be further provided. In this case, the reserved music is the music registered at the top in the reservation queue, and the wireless microphone is assigned identification information in advance, and is associated with the reserved music by the microphone information management means.

  The mobile karaoke performance device of the present invention can make the karaoke performance device self-run to the position of the wireless microphone based on the microphone position data of the wireless microphone, the current position data, and the movement path connecting both positions. Therefore, since the karaoke performance device is self-propelled to the position of the wireless microphone, there is no need for the karaoke person in charge of the singing of the next song and the confirmation of the position, and the karaoke person's labor can be reduced.

  In addition, when the microphone position data of the wireless microphone is compared with the current position data, and if the two match, it is assumed that the performance of the music is automatically started as if it reached the target location Can further reduce the labor of karaoke staff.

  In addition, when the wireless microphone is provided with identification information in advance and is configured to be associated with the reserved music by the microphone information management means, the karaoke performance device is sequentially placed at the position of the wireless microphone used by the song singer of the reserved music. Can be moved, so the labor of the karaoke staff can be further reduced. Note that the reserved music in this case is the music registered at the top in the reservation queue.
