Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the functional block diagram of the portable karaok audio amplifier of an embodiment of the present invention；
Fig. 2 is the flow chart of the method for a kind of portable loudspeaker box realization Karaoke of an embodiment of the present invention.
Detailed description of the invention
In conjunction with accompanying drawing, presently preferred embodiments of the present invention is elaborated.
Fig. 1 illustrates the functional block diagram of the portable karaok audio amplifier of an embodiment of the present invention, as it is shown in figure 1, this audio amplifier 11 includes transmission accompaniment module 103, user sings module 101, echo cancellation module 105, stereo process module 107 and music playing module 109.
Transmission accompaniment module 103 is for receiving the audio accompaniment of the selected song of mobile terminal, and sends into stereo process module 107；In the present embodiment, mobile terminal can transmit audio frequency by bluetooth or WIFI communication mode to audio amplifier 11.
User sings module 101 for receiving the acoustical signal that wireless microphone gathers, and obtains wave audio and sends into described echo cancellation module 105；In the present embodiment, wireless microphone can be wireless microphone or the mobile terminal with microphone apparatus.
Echo cancellation module 105, for described wave audio is carried out echo cancellation process, obtains people's sound audio, and people's sound audio is sent into stereo process module 107.
Stereo process module 107, for described audio accompaniment and described people's sound audio are carried out stereo process, obtains Composite tone.
Music playing module 109 is for receiving the described Composite tone of stereo process module 107 output and playing out.
Specifically, the echo in described wave audio is carried out Processing for removing according to described Composite tone by echo cancellation module 105.
Specifically, echo cancellation module 105 obtains described people's sound audio after removing described Composite tone in described wave audio.
Fig. 2 is the flow chart of the method for a kind of portable loudspeaker box realization Karaoke of an embodiment of the present invention.The portable karaok audio amplifier of the method embodiment as shown in Figure 1 runs.
In step S101, transmission accompaniment module 103 receives audio accompaniment.When user wants to use Karaoke audio amplifier 11, user takes out mobile terminal, selects the song wanting to sing on mobile terminals, and mobile terminal will pass to audio amplifier 11 the audio accompaniment of song；Transmission accompaniment module 103 on audio amplifier 11 will receive the audio accompaniment of the selected song of mobile terminal, is then fed into stereo process module 107；In the present embodiment, mobile terminal can transmit audio frequency by bluetooth or WIFI communication mode to audio amplifier 11.
