Detailed ways

A kind of mobile terminal of the present invention realizes the device of karaoke function, its specific embodiment is as shown in Figure 1, microphone MIC input circuit, MTV playback circuit, selection circuit and two-way sound output circuit; Two-way sound output circuit respectively It is a left channel output circuit and a right channel output circuit. The MTV playback circuit plays background music through one sound output circuit; the voice output of the MTV playback circuit and the output of the MIC input circuit are connected with another sound output circuit, and the selection circuit passes the voice through this sound according to the control signal of the main controller of the mobile terminal. The output circuit plays.

The method for realizing the karaoke function of the mobile terminal based on the device for realizing the karaoke function of the mobile terminal according to the present invention, its specific implementation method is:

Implementation Mode 1

as shown in picture 2:

Step 21, judging whether the main controller of the mobile terminal requires to realize the karaoke function of the mobile terminal, if yes, then perform step 22, otherwise the mobile terminal is normally on standby;

Step 22, the main controller of the mobile terminal receives the voice signal of the MTV playback circuit and the MIC input circuit;

Step 23, the main controller of the mobile terminal decodes the received sound signal of the MTV playback circuit into a background music signal and an original singing sound signal;

Step 24, the main controller of the mobile terminal discards the original voice;

Step 25, the main controller of the mobile terminal outputs the background music signal from the left channel output circuit; outputs the received voice signal from the MIC input circuit through the right channel output circuit; realizes the karaoke function.

In this step, the main controller of the mobile terminal can of course output the background music signal from the right channel output circuit; output the received voice signal of the MIC input circuit from the left channel output circuit. Realize karaoke function.
