Embodiment
The utility model embodiment comprises in microphone, set-top box, the set-top box and is provided with mainboard, it is characterized in that: be provided with square wave generation circuit in the described set-top box, the single-tone decoding circuit, switch is led and is sung testing circuit, voice signal treatment circuit, voice are led and are sung testing circuit, the microphone output circuit; The signal input single-tone decoding circuit of square wave generation circuit output, the output of single-tone decoding circuit are connected to switch and lead and sing the testing circuit input end, lead through switch and sing the interface microcontroller of sending into mainboard after testing circuit is handled; The voice signal of microphone, input microphone output circuit, input to the voice signal treatment circuit simultaneously, the output of voice signal treatment circuit is connected to the voice of set-top box and leads the input end of singing testing circuit, lead the interface microcontroller of singing testing circuit processing back input mainboard through voice, described voice signal treatment circuit is made up of voice signal amplifying circuit and voltage comparator circuit, and described switch is led and sung testing circuit and be made up of frequency-discriminating circuit and its peripheral components.。
Above-mentioned square wave generation circuit and single-tone decoding circuit are made up of integrated circuit LM567 and peripheral components thereof.
Above-mentioned voice signal testing circuit is made up of chip NJM4580 and LM393 and peripheral components thereof; People's sound input chip NJM4580 through its filtering and amplification, compares voice signal to LM393, if signal is excessive, LM393 can overturn and export a signal.
Concrete principle of work of the present utility model is:
1. antiphonal singing pattern, antiphonal singing pattern adopt is to detect current microphone to open or close and realize.When microphone is opened, inner chip piece LM567 produces the square wave of 100K and gives microphone, and receive square-wave signal and phase-locked affirmation back output useful signal at output terminal a slice LM567 of microphone, switch is led and is sung testing circuit and detect this signal, and send microphone by single chip machine controlling circuit and open information to set-top box, set-top box software removes the original singer of song and only stays vocal accompaniment, has realized opening the function that microphone automatically switches to vocal accompaniment; When microphone is closed, LM567 in the single-tone decoding circuit does not receive square wave, output signal not, after switch is led and is sung testing circuit and detect, export the microphone shutdown signal immediately, single chip machine controlling circuit sends information that microphone closes to set-top box then, set-top box software switching sound channel, the former vocal accompaniment of joining in the chorus is all kept, realized closing the function that microphone switches to the original singer; This pattern is fit to be used for single people and sings lovers' song.
2. lead the pattern of singing.When the singer sings, through chip NJM4580 filtering and amplification, voice signal is compared to LM393, if signal increases, LM393 can overturn and transmit a signal, and voice are led to sing and exported " voice are opened " signal to single chip machine controlling circuit after testing circuit detects this signal, and single chip machine controlling circuit sends " voice are opened " information and gives set-top box, set-top box software removes the original singer of song and only stays vocal accompaniment, has realized that the singer sings promptly to automatically switch to the function of vocal accompaniment; When the singer does not sing, the voice signal amplitude is lower than the comparison amplitude of LM393, signal does not overturn, voice are led and are sung testing circuit and can export " voice are closed " signal and give single chip machine controlling circuit, single-chip microcomputer sends " voice are closed " information and gives set-top box, set-top box software switches sound channel, the former all reservations of vocal accompaniment of joining in the chorus, has realized that the singer stops to sing to switch to original singer's function; This pattern is fit to when you sing to go down certain first song, and set-top box is connected up the original singer automatically.
3. general mode is turned off to lead and is sung the plate all functions, and microphone signal is sung the plate processing directly to power amplifier without leading.Remove above function, lead and sing the noise that plate can also be eliminated opening of microphone and close generation, this is denouncing of certainly existing on general microphone.。The utility model modern design, effective, its market outlook are considerable.
