Background technique

As leisure and entertainment are paid more and more attention, singing, a popular activity that is widely loved by everyone, is also popular. In addition to going to KTV and karaoke to sing with good friends, installing karaoke machines at home to share with family and friends Singing and having fun are also common. Generally, the existing karaoke is to connect the karaoke machine with the TV set with a transmission line, and transmit the audio-visual signal of the karaoke machine to the TV and the loudspeaker display. The karaoke machine has a large-capacity hard disk to store a large amount of song data. Order the songs you want to sing through several songbooks or song-on-demand systems. However, due to the large number of songs, there are Chinese, Taiwanese, Cantonese, Japanese, English, and children's songs. Among so many songs, those who really like to sing, the songs they can sing are actually limited. The songs I like to sing may not be in the songbook. And when a new song is released, many new song data will be stored in the hard disk one after another. There may only be a few songs that are liked, but a large-capacity hard disk is still required for storage. Therefore, a hard disk that stores a large amount of song data sometimes just increases the cost for consumers and is not practical. And when choosing a song, facing so much song information, it is not easy to click.

In view of the fact that there are many existing karaoke songs, but most of them are disliked or unsuitable songs, in addition to increasing the cost of the storage device, the actual benefits are not large, and it is not easy to order songs, which does not actually meet the needs of users. Demand, therefore, the utility model improves at the problems referred to above.
