Influenced by the development of music and the popularity of music videos, the karaoke craze spread rapidly among the general public.

Conventionally, to karaoke, go to KTV (Karaoke TV) was selected and played through the song selection system provided by KTV to sing a micro song. However, going to KTV and singing was not only expensive but also hygienic because it was shared with other consumers. Thus, the effect of entertainment, but still did not receive much favor from consumers.

In order to solve the above problem, a household half cycle has been proposed. This home-made half-cycle has a large number of song files stored inside, and can be sung at home by connecting a home TV and a speaker and providing a microphone to the user.

In addition, such a half-cycle is usually to be used outdoors, but since most of the hardware components of the half-cycle is in the user's house, it is very troublesome to use it in another house. For example, a user's home is generally equipped with a television and a speaker. Both user's mobile devices (eg mobile phones and laptops) can play song files purchased on their own or on the Internet. In addition, since the user's mobile phone itself has a listening function, it can also be used as a microphone. As described above, such hardware means cannot be effectively applied, and it is very wasteful for the user to purchase the half cycle.

In view of the above, the research direction of researchers in this area is to reduce the cost of purchasing karaoke songs and to reduce the cost of purchasing half cycles by effectively applying and using existing hardware means. to be.

    It is a main object of the present invention to provide a portable accompaniment system, an accompaniment method and an application, and to allow a user to sing and apply a song by combining an extension device and an application using hardware installed in the mobile device itself. .

In order to achieve the above object, the present invention includes a receiving end accompaniment device and at least one transmitting end accompaniment device. The receiving accompaniment device is stored internally, and generates a song list according to the songs uploaded to the transmitting accompaniment device and provides it to the transmitting accompaniment device, and the transmitting accompaniment device sends a selection command to the receiving accompaniment device according to the song list. Configure the play queue. The receiving accompaniment device generates a music signal by reproducing the internally stored song files according to the play queue order, and finally receives an external audio signal by the transmitting accompaniment device and transmits it to the receiving accompaniment device to mix with the music signal. .

The present invention has the effect of using a hardware component of the mobile device itself compared to the prior art, and combining the other speaker device and the application program to configure a complete and portable accompaniment system.
