Wherein, the radio unit is provided with switch button and mode switching key.
A kind of karaoke OK system application method of the automatic voice that disappears, includes the following steps：
（1）First, program source, the image information of program source is selected to be transferred to image by network element and play list by network element
Member, audio-frequency information are transferred to control unit by network element；
（2）Then, it opens radio unit and switches to automatic mode, under the pattern, the sound pick-up of radio unit arrives sound in pickup
After wave, handled by amplifier and limiter, then be transmitted at control unit；
（3）The signal that radio unit is sent into first is compared operation by control unit by DSP with the preset value in memory, works as receipts
When the signal amplitude of sound unit input reaches preset value, start the distinguishing voice mechanism that disappears automatically.
Wherein, step（2）In, radio unit pattern switching includes manual switching and automatic switchover two ways, wherein hand
Dynamic switching is realized by pressing mode switching key, after automatically switching through user's sounding, by radio unit automatic identification voice
It switches over.
Beneficial effects of the present invention are presented as：The present invention is intended to provide a kind of karaoke OK system of automatic voice that disappears and its making
It with method, by combining control method for frequency and phase method to eliminate voice, can be not necessarily to operate to intervene, when microphone pickup is to using
After the sound wave that person sings, realize that the voice that disappears automatically, the sound wave when being not picked up the singing of user then automatically open former sound,
And there is no limit can use standard MTV sources of sound, can also use when playing common audio and video, can realize to source of sound
Disappear the function of voice, and use scope is wide, highly practical.

Specific implementation mode
The specific implementation mode that the invention will now be described in detail with reference to the accompanying drawings：
As shown in Figs. 1-2, a kind of karaoke OK system of the automatic voice that disappears, including radio unit 1, control unit 2, network element 3,
Image broadcast unit 4 and sound playing unit 5, the radio unit 1 and the network element 3 are distinguished in which can transmit audio signal
It is connected with described control unit 2, the network element 3 provides program source and is connected with the video player, the control
Unit 2 is electrically connected by AV amplifiers 6 and the sound playing unit 5.
Wherein, the radio unit 1 is provided with the sound pick-up 7, amplifier 8 and limiter 9 being electrically connected with each other, the control
Unit 2 processed is provided with DSP denoisers 10, and the radio unit 1 is electrically connected at the DSP denoisers by the limiter 9
10, on the audio transmission that the sound pick-up 7 is included to described control unit 2.
Wherein, the radio unit 1 is provided with switch button 11 and mode switching key 12.
A kind of karaoke OK system application method of the automatic voice that disappears, includes the following steps：
（1）First, program source, the image information of program source is selected to be transferred to image by network element 3 and play by network element 3
Unit 4, audio-frequency information are transferred to control unit 2 by network element 3；
（2）Then, it opens radio unit 1 and switches to automatic mode, under the pattern, the sound pick-up 7 of radio unit 1 is arrived in pickup
After sound wave, handled by amplifier 8 and limiter 9, then be transmitted at control unit 2；
（3）The signal that radio unit 1 is sent into first is compared operation by control unit 2 by DSP with the preset value in memory, when
When the signal amplitude that radio unit 1 inputs reaches preset value, start the distinguishing voice mechanism that disappears automatically.
Wherein, step（2）In, 1 pattern switching of radio unit includes manual switching and automatic switchover two ways, wherein hand
Dynamic switching is realized by pressing mode switching key 12, after automatically switching through user's sounding, by 1 automatic identification language of radio unit
Sound switches over.
The voice automatic discrimination mechanism that disappears is specially：First the sound of currently playing Karaoke left and right acoustic channels is compared,
If the source of sound of left and right acoustic channels is identical, frequency of use control method, while eliminating the human voice for including in left and right acoustic channels；Such as
The source of sound of fruit left and right acoustic channels is different, then enables phase method and eliminate voice.
The sound that source of sound after elimination voice is picked up with radio unit 1 carries out after the DSP processing by control unit 2
The audio mixing is sent at AV amplifiers 6 by audio mixing therewith, sound playing unit 5 is driven by AV amplifiers 6, to make a sound.
When DSP is compared by operation, and the sound amplitude that radio unit 1 is picked up is less than the preset value in memory, automatically
Closing disappears voice function.
Radio unit 1 in automatic mode, can close the automatic human voice patterns that disappear by mode switching key 12 again.
