The present invention relates to a karaoke system and a karaoke service method that can implement a karaoke function using a portable terminal.

In recent years, the spread of personal mobile communication as well as wired communication network has been made exponentially, and the portable terminal for mobile communication is becoming a necessity of social life. In general, a mobile communication system is composed of PCS (Personal Communication System), CDMA, or GSM (Global System Of Mobile Communication), so that other mobile communication terminals can be used while the user is moving through a portable mobile terminal. It is also possible to conduct voice calls and text communications with landline telephones.

As the wide spread of mobile communication and the rapid development of wireless network based and portable terminal technology, mobile communication companies have developed various additional services linked with wireless communication network to differentiate from other companies. In addition to providing convenience and rich cultural content.

In particular, in recent years, memory technology has also undergone a rapid development, and even though the overall size of the mobile communication terminal is small, not only can a large amount of data be stored, but also a karaoke service using the mobile communication terminal can be used. This is expected.

The karaoke service using the mobile communication terminal is one of the services that have gained much response from the general public due to the fact that there is no time limit and no place limit.

However, the karaoke function serviced by the conventional mobile communication terminal has a structure of outputting only the music file stored in the terminal, and the user has a disadvantage in that the song is separately listened to while listening to the music output from the terminal.

As the music of the selected song and the voice of the user who sings the song are not output together, it is difficult to see that the karaoke through the conventional terminal implements a proper karaoke function.

In addition, the selected music is limited to output only through the speaker installed in the terminal, there is a limit to the output amount, in order to increase the output, it was inconvenient to connect a separate speaker to the terminal.

The present invention has been made to solve the above problems, an object of the present invention is to synthesize the voice of the user in the karaoke function implemented as a portable terminal and to output the karaoke system and a karaoke service method through a portable terminal In providing.

In addition, another object of the present invention is to provide a karaoke system and a karaoke service method through a portable terminal capable of transmitting and outputting a music signal output from the portable terminal to an external audio device.

In order to achieve the above object, the karaoke system of the present invention mixes a MIDI signal unit for realizing music, a microphone to which an external voice is input, a music signal output from the MIDI signal unit, and a voice signal output from the microphone. And a portable terminal including a mixing unit and a wireless transmitting unit for modulating the mixed signal output from the mixing unit into an FM signal and transmitting the mixed signal to the outside.

In addition, the karaoke system of the present invention may include an external sound device for receiving and outputting the FM signal transmitted from the terminal.

The wireless transmitter includes an FM signal modulator for modulating the mixed signal output from the mixer into an FM signal, a band selector for selecting the modulated signal as an external frequency band, and amplifying the selected specific band frequency. It may include an amplifier for, and an FM transmitter for transmitting the amplified signal to the outside.

In addition, the external audio device is not particularly limited as long as the device is equipped with an FM receiver, and may be an audio of a vehicle, a portable audio player, or another portable terminal.

Accordingly, the user's voice and the selected music can be output through the external audio device, and the output can be increased according to the speaker provided in the external audio device, so that the karaoke function can be properly implemented.

The karaoke system may further include a karaoke server for transmitting karaoke information and music selected to the portable terminal.

On the other hand, the service method of the present invention for servicing a karaoke through a portable terminal is a step of selecting a karaoke function and selecting a desired song using a portable terminal, mixing the selected music and the external voice input to the terminal from the outside Step of selecting whether or not the external output of the mixed song, if the external output is selected, modulating the mixed signal into an FM signal, selecting a frequency band of the modulated signal, amplifying the selected specific band frequency And transmitting the amplified signal to an external sound device.

The service method may further include receiving a signal transmitted from the terminal at an external sound device, and outputting the received signal from the external sound device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.
