Portable vocal system, vocal method and application

The present invention relates to accompaniment systems, and more particularly to accompaniment systems that are convenient for the user to carry around.

With the development of music and the popularity of music video (Music Video, MV), it quickly moved the general public to sing karaoke (karaoke).

Traditionally, when you want to sing karaoke, you need to go to the KTV box and use the song system provided by KTV to click and play the song accompaniment band, and then sing with a microphone. However, there is a lot of money to pay for singing in KTV, and the KTV box is shared with other consumers, and health problems are worrying. Therefore, although very entertaining, it is still rejected by many consumers.

In order to satisfy the above-mentioned ethnic groups, there has been a family-style phonograph in the market. The home karaoke machine mainly stores a large number of song files internally, connects the home TV and speakers, and provides at least one microphone for the user. In this way, the user can sing at home. However, although the home type phonograph provides the user to sing at home to solve the problem that the user is unwilling to go to the KTV, the problem that the family phonograph is too large and too heavy causes the user to move freely. Therefore, once it is placed in the user's home, it will usually not be moved to another place. It is a pity.

Therefore, the market has developed a portable phonograph, such as the new patent of the Republic of China Patent No. M383885, which proposes a portable multimedia phonograph with a retractable screen. Mainly, the components such as the screen, the sound amplifying device, the microphone and the microphone stand are shared in one case, and the wheel and the puller are attached to make the user easy to move. The biggest advantage is that it can be carried and moved freely so that the user can sing anywhere.

However, the above-mentioned portable phonograph has a large number of hardware components in one body, and the phonograph is sold externally, and a large collection of various song files commonly used for internal storage needs to be authorized, so usually the price is not Fiji. Moreover, such a phonograph is usually used by the user outdoors, and it is superfluous if it is used only in the home of a different person. Most of the hardware components on the phonograph are already present in the user's home. For example, a general user's home usually has a TV and a speaker, and the user's mobile devices (such as mobile phones and notebook computers) can play song files purchased by home or online. Furthermore, the user's mobile phone itself has a radio function and can also be used as a microphone. As described above, if the existing hardware devices cannot be effectively used, it is wasteful for the user to separately purchase the above-mentioned valuable phonograph.

In view of this, how to effectively use the existing hardware devices, after the clever cooperation, allows the user to use the karaoke singing, eliminating the expensive cost of purchasing the phonograph, that is, the research and development personnel of the technical field Direction of the research.

The main purpose of the present invention is to provide a portable accompaniment system, a vocal method and The application allows the user to combine the expansion device and the application with the hardware components of the mobile device to perform on-demand and singing of the song.

To achieve the above object, the present invention comprises a receiving end singer device and at least one transmitting end singer device. The receiving end accompaniment device generates a list of songs according to the songs stored in the internal storage and the vocal equipment of the transmitting end, and provides a list of songs to the singer device of the transmitting end, and the singer device of the transmitting end sends a selection command to the receiving accompaniment device according to the song list to constitute Play the queue. The receiving end accompaniment device plays the internally stored song file according to the order of the playing queue to generate the music signal, and finally receives the external singing voice signal by the transmitting end accompaniment device, and transmits to the receiving end accompaniment device and the music signal for mixing.

The effect of the present invention over the prior art is that the hardware components of the mobile device, together with the additional expansion devices and applications, share a complete and easy to carry accompaniment system. This not only saves the user's expenses for purchasing the accompaniment system, but also makes the vocal system more convenient and easy to popularize due to the small size, easy portability, and availability of the mobile device.
